Description

200844693 IX. Description of the invention: [Technical field of invention] The present invention is a holographic display device, and particularly includes a first electronically-positioned spatial light eliminator and a first electronically-positioned spatial light modulator, and is permeable to one Or multiple virtual observer windows to see the holographic reconstructed hologram display device. [Prior Art] _ C〇mpUter-generated vide〇holograms (CGHs) are compiled from one or more spatial light modulators (SLMs); space The light modulator can include electronic or optically controllable elements. These components encode the hologram values based on the image hologram to achieve the purpose of modulating the amplitude and phase of the light. Computer-generated image holograms can be calculated, such as by coherent ray tracing, by simulating the reflection of light reflected by the scene, and by reference waves, or by Fourier or Fresnel. Conversion. An ideal spatial light modulator is " can represent any complex number of values, that is, control the phase and amplitude of the incoming light wave. However, a typical spatial light modulator can only control one of the amplitudes or phases, with adverse effects that affect other characteristics. The amplitude and phase of the modulated light can be varied in several ways, such as using an electronically addressed liquid crystal spatial light modulator, an optically addressed liquid crystal spatial light modulator, a magneto-optical spatial light modulator, a micromirror device, or an acousto-optic light. Modulator. The modulation of light may be spatially contiguous or consist of individual addressable elements, which may be one or two dimensional, binary, multi-level or continuous. 6 200844693 The value to encode the 'proper noun' code means to provide spatial light modulator control reconstruction. The user map and the flat code enable the two-dimensional scene to be encoded by the spatial light modulator to encode the hologram of the μ-space optical modulator. The green hologram is encoded on the air. ^ :Auto, 、, 屯Stereoscopic display panel, the observer can observe through the image hologram. ^ Lightwave _ Optical 4 is built. The 3D scene is extended between the observer's ^ ^ and : inter-optical modulator or even after the spatial light modulator Space & Space Light Modulators can also be coded using image holograms, allowing observers to observe reconstructed 3D scene objects before spatial light modulators, while spatially or otherwise Other objects are observed. 1 Light-emitting components are better in light transmission, and the interference caused by the rays is at a defined position, and the spatial coherence length exceeding a few millimeters can provide holographic reconstruction. There is sufficient resolution in one dimension. This type of Lu-shaped light will be called ''full dimming'). * For the county foot _ _ _ sex, the spectrum emitted by the light source must be limited to - - the narrow wavelength of the turn, that is, must be close to monochrome. High-brightness illumination - The spectral bandwidth of the polar bodies (LEDs) is narrow enough to ensure time homology of holographic reconstruction. The diffraction divergence on the nucleus of the nuclear county is related to the wavelength, meaning that only one monochromatic source will result in a strong reconstruction of the target point. Long's rewards lead to wide target points and reconstruction of the model. The spectrum of #狮 can be considered monochrome. Light-polar (XED) light # Width is narrow and can help better reconstruction. 7 200844693 The spatial separation is related to the lateral width of the light source. Conventional light sources, such as light-emitting diodes (LEDs) or cold cathode light-emitting lamps (CCFLs), can also meet these needs if they emit light through a 7-inch gap. The light from the laser source can be viewed as a point from the diffraction limit _ light_emission, according to the model_purity, which will produce a sharp reconstruction of the target, ie each target point is reconstructed as a diffraction limit. The light generated from the non-conforming light source in the work room is laterally extended and causes reconstruction of the I. (4) The situation is determined by the wide size of the target point of reconstruction at a given location. In order to use a spatially non-coherent light source for hologram reconstruction, a compromise must be found between the brightness and the lateral width of the source of the aperture. Smaller sources will give better spatial coherence. For example, if U is a longitudinally extending viewing wire, the straight line can be regarded as a point, a ', and the light wave can transmit in the same direction in the same direction, and it is not in the same direction. The eight 5' hologram reconstructs the % scene by super-overlapping the waves in the horizontal and vertical directions. The above image hologram is referred to as a full parallax hologram. Reconstruction = Objects can be viewed as moving parallax in the horizontal and vertical directions, just like real objects. However, the phase of the visible light needs to have a high resolution in the horizontal direction of the spatial light modulation n (four). 8 200844693 There is a holographic reconstruction. The office led to the 4th Division of the oblique parallax. The perspective does not change vertically. A holographic image with only a series of parallax _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The hologram 4 depends on the oblique direction, and (4) the straight direction does not decrease in the vertical direction less than the full side of the full parallax. Only vertical parallax (10)

The hologram is available as a domain but more than a ride. A full-image button occurs only in the vertical direction and produces a reconstructed object with a vertical moving parallax. There is no moving parallax in the horizontal direction. Since the perspectives of the left and right eye views are different, the perspective views must be generated separately. DISCUSSION OF RELATED TECHNOLOGY Typically, devices for generating three-dimensional images are less tight, requiring complex and bulky optical systems that make them incapable of being used in portable devices, or in handheld devices such as mobile phones. . For example, the job coffee is used to generate a large three-dimensional map _ , and the length of the device is in meters. Referring to Difficult 4/〇 44659(10)嶋, the device for reconstructing a three-dimensional image of the image has a thickness of more than 1 (cm). Therefore, the above-mentioned conventional device has an excessive thickness for a mobile phone or other portable, handheld or car display device. In W0 20_44659 (_06/_994), it is mentioned that the two-dimensional scene is reconstructed by the diffraction of the coherent 9 200844693; the device_light source or the linear light is focused on the gamma technology. She is in the transmission mode of the full-space optical modulator in the transmission mode at least in the "virtual observer window": two-dimensional scene (for the description of the virtual observer window and related technology, please refer to the attachment ^ π). Each virtual observer window is placed close to the observer's eyes, and the upper limit is limited, so the virtual observer window is in the single-drilling class, so each eye can be given three _ _ in the _ (four) Du _ complete reconstruction The tapered cross-dissection is extended between the surface of the Langguang machine and the virtual inmates. In order to make the full construction no name, the size of the virtual_inspector must be re-established - a periodic interval of the diffraction class. However, this must be at least large enough to allow the observer to see a complete reconstruction of the 3D scene via the window. Another eye can be viewed through the same virtual weaver window or a second virtual observer window generated by the second source. At this point, a typically large visible area is limited to the locally set virtual observer window. The f_ solution is to reconstruct the large areas of miniaturization produced by the surface of the conventional high resolution spatial light modulator to reduce the size of the virtual observer window. This will result in a smaller, geometrical, and/or angle of incidence, as well as a computational device that utilizes a 'Shabber' level, i.e., a modulator resolution sufficient to achieve high quality instant holographic reconstruction. However, it is known that a method of producing a three-dimensional image exhibits the disadvantage of a large volume, large capacity, heavy weight, and expensive warp focusing of 200844693 due to the large spatial light modulator surface area. Therefore, the device will have a large thickness and weight. Another disadvantage is that when the silk is too sharp, the color of the secret edge is severely reduced and the quality of the reconstruction is reduced. A modification of the light source improvement method comprising a lenticular array is mentioned in US 20 〇 6/25 _ _ which is made in the domain _ image, as a reference. ... The on-the-job) mentioned the mobile phone that produces 3D images. However, the three-turn image mentioned is produced by an automatic read display. The problem with auto-stereoscopic display producing a three-image is that the viewer typically perceives that the image is inside the display, while the viewer's eye is directed onto the surface of the display. Watching in many instances: #The difference between the focus of the eye 3 and the perceived position of the two-dimensional image will likely result in a county where the user is convinced. In instances where _Full Image technology produces 3D images, these problems will not occur or be greatly reduced. SUMMARY OF THE INVENTION In a first aspect, a holographic display device is provided, including a first electronic formula, a spatial illuminator H, and a second electronic locating miscellaneous ray, which can directly touch her and Amplitude, and holographic reconstruction is seen in the towel through one or more virtual viewing bay windows. A holographic reconstruction can be observed through one or two virtual observer windows. The display can be illuminated with backlights and microlenses. The holographic display device allows the light source to be a light emitting diode. 11 200844693 A holographic display device allows an electronically-positioned light to adjust the phase, and another electronically-spaced spatial modulator to modulate the amplitude. The holographic display device allows one electronically-positioned spatial light modulator to modulate the combination of phase and amplitude, and the other electronically-spaced spatial tonal modulation modulates the different combinations of phase and amplitude. The holographic display device allows electronically-addressed spatial light modulators to be positioned between φ 〇 /, _ electronically located to the adjacent layer of light or small spacing. The electronic address space is fine-tuned to directly or indirectly connect to the entity. The holographic display device allows the light source to be fixed and physically connected directly or indirectly to the electronic address spatial light modulator. The holographic display device can cause the electronic address spatial light modulator to have an array of pixels associated with one or more virtual observer windows.

I The diffraction of light from the first electronically addressed spatial light modulator to the second electronically addressed spatial light modulator utilizes the Fresnel diffraction law, but does not include Fraunhofer. The law of diffraction. 12 200844693 Full-image transposition can be transmitted by each pixel of the m-th address space f-modulation _ _ _ _ is a person shot on the pixel corresponding to the second electronic address space optical modulator, considering The case of a two-dimensional profile. The holographic display device can reduce the pixel aperture of the first electronically-positioned spatial light modulator to minimize crosstalk, and is transmitted through Ficoll, but does not include the Fraunhofer diffraction rules. The isolation layer can be used to minimize the electromagnetic field by purely electronically arranging the optical contactor, preventing an electronically addressed spatial light modulation II from adversely affecting the performance of the adjacent electronic address space. Lens _ can be placed between electronically addressed spatial light modulators to minimize crosstalk. The $ pitch can be minimized by reducing the pixel hole (four) squares in the first electronically addressed spatial light modulator. The Chevron and Fiji diffraction laws reduce the pixel aperture of the first-electronic address m-modulation II towel to minimize crosstalk. The fiber optic panel can be placed between the f-spots to minimize crosstalk. The holographic display unit allows the virtual observer window to be spaced or time multiplexed for placement. 13 200844693 The holographic display device can make the display operable to re-sequence (10) hologram with the left eye and the right eye of the inspector's left eye and the right eye. The display does not require any projection lens to produce a second image that is focused on the screen and has no distance from the optical far field. ^

The king image can be used to transmit a holographic image to each eye of the viewer using a beam splitter. The source fiber is placed in the first holographic display device. The county pointing component is imaginary. The interface between the region and the matrix is the prismatic shape, or the part of the column of the ball _, light_mei_ Zhuangqi = or 疋 round beam pointing to the meta-strain η _ _. ^ • per 10,000 control, to change into the first bundle # 曰 to the workpiece is composed of the liquid crystal region inside the isotropic body material, 70 parts of the The refracting or diffractive property variator, the light source, and the illuminator, such as the illuminator, allow the electronically addressed spatial light tone 200844693 to be placed in a Lai box, and the array is enlarged by 10 to 60 times. And at t, the light source is illuminated by the lens holographic display device _f light and the microlens array. The microlens 歹J provides locality in a small area of the display that is the only part of the display that encodes the given information for the reconstructed object. Show crying ^ contains reflective polarized #.

[Embodiment] The tight combination of the A. Infrared organic light-emitting diode display and the optically-addressed spatial light modulator UU is provided by the optical-addressed space county _ and the optically-addressable space light modulator A close-knit combination of an infrared-emitting display that writes a human pattern, such a combination of age-appropriate _ conditions to produce a three-dimensional image. 15 200844693 Optically addressed spatial light warm n-package light n-layer with a liquid helium (LC) layer at the conductive electrode 1. When a voltage is applied to the electrodes, the light pattern incident on the photoreceptor layer is converted to a liquid crystal layer for modulating the read beam. In conventional techniques, the incident light = sample is supplied by an electronically addressed spatial light modulator (EASL) y_variant written beam. The electronically addressed spatial light machine II is illuminated by a light source and imaged to an optical疋 空间 空间 通常 | 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常 通常The advantage of the t-sampling spatial light modulator is that the optically-addressed spatial light-modulating material has a continuous, non-pixel or non-slave = structure' and the electronically-addressed spatial light modulation is turned into a pixel structure. Sharp edges are produced on the space distribution. · This sharp edge is equivalent to a high spatial frequency. High spatial frequencies will result in a wide-fired naval in the optical far field. Therefore, the electronic neon space light tone becomes rich in the optical far field. The occurrence of optical diffraction processing (10) must be eliminated by known techniques such as spatial filtering. One additional filtering in the wire processing requires additional steps, which can make the device thicker = a waste of light. Optically-addressed spatial light modulation Type of device: 疋月b is enough to achieve continuous grading in the optically-spaced space. The continuous pattern allows the light intensity to have less (four) chord changes in any given direction to the direction of beam propagation. Therefore, less steep meal has a higher spatial frequency concentration than the edge of the pixel produced by the electronically-addressed inter-mode optical modulation H device. In the device of the photo-contact device, the lower turn-up space The frequency can be boosted and compared to an electronically addressed spatial light modulator compared to an electronic addressed spatial light modulator, the optical === device can be a bistable device. Therefore, optical addressing _ 调 μ Comparable electronic amps have the ability to increase the battery life of portable devices or handheld devices. In less detail, a compact device that does not require imaging optics is introduced. Optically-spaced spatial light modulators are utilized. Infrared green ancient "Deyi-polar_~= body display writer. Organic light-emitting connection optically-spaced space light modulator to form a tight rear garment. The organic light-emitting diode can be laid. Type to Electro-optical organic light two shop _. Silk-style New Lang light tone (four) can be composed of a number of smaller, deployable optical positioning Lang fine series. Organic light-emitting diode _ bribery optical New Zealand Lang light Wei as tight as The combination may be transparent. A transparent organic light emitting diode display is what is currently known, for example, in the following, Organic Light Emitting Diode Materials section. In an example, an organic light emitting diode The close combination of the body display and the optically-addressed spatial light modulator is an edge-injection from the opposite side to the three-image, and the visible light is transmitted to the observer via the organic light-emitting diode and the wire-addressed spatial light modulator. A better way is to use organic light-emitting __!! to emit infrared light to write the infrared-sensing photoreceptor layer of the optical modulator. The human eye is not sensitive to infrared rays, so the observer cannot see. Any of the light generated by writing a beam from an infrared ray. As another example, the organic light-emitting diode display _ optically-addressed spatial light modulators can be used to make the write beam and the read beam incident on the opposite side of the freshly-spaced light. In another example, the close combination of the organic light emitting diode display and the optically addressed spatial light modulator allows the reflective layer to be on the side of the optical: address spatial light modulator, which is an organic light emitting diode. The opposite side of the display allows the two-dimensional image to be viewed from the same side of the optically-addressed spatial light modulator, that is, on the side where the organic light-emitting diode display is located, and the illumination source is also like the organic light-emitting diode In the case of the silk-addressed space, the light is on the Weiguan side: this is an example of a reflective display. In the embodiment of φ comprising an array of infrared organic light-emitting diodes, the infrared light-emitting, organic light-emitting diode allows a combination of amplitude, phase or amplitude and phase of visible light transmitted by the optically-spaced fine-tuning space. Control, causing the hologram to be generated in the optically addressed spatial light modulation. The optically addressed space _ variator may comprise a pair of transparent spacers coated with two electrically conductive films as described in the reference US 4,941,735. A continuous or discontinuous photosensitive film can be applied to one of the conductive films. Bistable and sturdy ferroelectric liquid crystal or some other type of liquid crystal can be confined between another 200844693 conductive film. The starter can be used to adjust the n-mode, silk type, and the optical fiber is spot-contacted by the beam.

However, it is better to have a non-laser light source (for example, a light-emitting diode, a firefly: a lamp) that is well-known for its two properties. Laser light source - viewer / shirt point, relatively expensive and all about the damage hologram display view or 疋 omnidirectional display device _ read personnel turn, etc. possible security question t element 1 〇 _13 thickness all Can be about a few centimeters or less. The component η can be fine-grained, so that the image of the pure (red, riding) light is directed to the element 12, although a color transition is not required if a colored light source is used. The τ member 12 is an infrared organic light emitting diode array on a transparent substrate. The infrared line organic light emitting diode array will cause each of the infrared organic light emitting diodes to emit light in the direction of the element 13 in parallel and conforming to the light emitted from the unique corresponding color pixel. Element 13 is an optical silk stray surface. The scalar-addressed spatial light, the variator, the infrared organic light-emitting diode array provides a write beam, and the component emits a Lu-shaped color beam as a read beam. The viewer located at point I4 from the close omni-image generator is at a distance - viewing the resident image from the direction of 15. The elements 10, 1 and U3 are configured to be physically connected (realally connected), each forming a layer of structure such that the whole is a single, uniform object. Physical connections can be direct. Or indirect 'if there is a thin intermediate layer, cover the film between adjacent layers. The physical connection can be in a small area that ensures correct _ mutual integration, or can extend to a larger area' or even the entire surface of the layer. The physical connection can be achieved by layer-to-layer bonding, for example by using an optical transfer glue to form a compact, recorded image generator I5' or by any other means (refer to the Summary Manufacturing Program, The Ο / 丄 element 10 may comprise one or two 稜鏡 optical films to increase the brightness of the display: a read film is known, for example as described in us 5, Tao 9_s 5,919,551, [the inner valley 70 pieces 10 Contains polarized elements' or a collection of polarizing elements. Linear polarizing sheets are one of them. Another example is reflective polarizers, which can transmit 20 200844693 up to a linearly polarized state, and reflect orthogonal linear polarization State _ such a sheet 疋 is known, for example, as described in US 5,828, 488. Another example is a reflective polarized 'transportable' circularly polarized state, and a reflection of orthogonal circular biased grievances - such Sheets are known, such as the inner valleys described in US 6,181,395. The element 10 may comprise a focusing system, which may be a compact 'eg lenticular array or microlens array. Element 1G may comprise its It is an optical element known in the field of backlight technology. Figure 4 is a side view of a conventional technique, pointing out the three focusing elements 1101, 1102, 1103 of the vertical focusing system 1104, in the form of a cylindrical lens arranged horizontally in the array. In the reference WO 2006/119920, the beam which is nearly collimated with the horizontal line source LS2 passes through the focusing unit 11〇2 of the illumination unit to the observer plane 〇p. According to Fig. 4, many line sources LS1, LS2, LS3 are Arranged one by one. The light emitted by each light source is spatially homogenous in the vertical direction and spatially non-coherent in the horizontal direction. This light passes through the transmission element of the optical modulator SLM. The elements of the image-modulated optical modulator SLM are only diffracted in the vertical direction. The focusing element 1102 is in the observer plane 〇p with several diffraction stages (only one is useful) imaging light source LS2. The beam is taken as an example of a focusing element 1102 that passes only through the focusing system 1104. In Figure 4, the three beams show the first diffractive class 1105, the zeroth diffractive class 11〇6, and the negative Diffraction class 1107. The line source allows for very high light intensity generation compared to a single point source. 21 200844693 uses multiple efficiencies and a full-image area of 7 lines of line source for each part of the reconstructed 3D scene. Improves effective light intensity. Another advantage is that no laser is used, and multiple sources (for example, after a slot that can be part of the shutter) can produce sufficient dimming. B. Two pairs of organic A close 'combination of the combination of the light-emitting diode and the optically-addressed spatial light tone (4). The mountain, in the implementation of the further step-by-step, can use two pairs of light-emitting diodes and optically-addressed space. The combination of f, in a tightly coupled way to adjust the vibration of k and her. In this way, the complex number of the city can be compiled in the transmitted light one by one. Embodiments include a close-in combination of an infrared organic light-emitting diode _ and an optical call-address spatial light modulator and a second infrared-emitting organic light-emitting diode array and an optically-spaced spatial light modulator A close combination of the series. The first pair modulates the amplitude of the transmitted light, and the second pair modulates the phase of the transmitted light. It is also possible to adjust the phase of the transmitted light by the first-pair modulation and the fine amplitude by the second pair of modulation. A close group of each of the organic light-emitting diode arrays and the optically-addressed spatial light modulators can be as described in Section A. The close combination of the two pairs of infrared organic light-emitting diode arrays and the optical button space change II is separated by infrared filtering. 22 200844693 Infrared rays pass through the infrared and receive infrared light without processing visible light. In the first step, the first infrared organic light emitting diode array is written in a pattern to improve the amplitude modulation in the first optical optical spatial modulator. In the second step, the outer-line organic light-emitting diode array writes a human pattern to provide phase modulation in the second optically-positioned Langguang modulator.

Therefore, this embodiment can be applied to generate a hologram to a two-dimensional image. The plane 'not visible' is an example of implementation. 2G is an illumination device for providing illumination of the p-region and (4) is capable of producing a three-dimensional map, and an example of a large-area image hologram is provided in the gallbladder. This type of device can be used as a white ___ cathode glory or a white light emitted by the focusing system on the focusing system = where the focusing system can be tight, such as a lenticular array or a microlens array for 2G The light source can be composed of red, green and blue lasers, or it can be composed of red, green and blue light-emitting tiles. However, non-laser sources (e.g., light-emitting diodes, organic light-emitting diodes, cold-yellow fluorescent lamps) having sufficient spatial coherence are better. The shortcomings of laser light sources, such as shooting spots on holographic reconstruction, relatively expensive and all the viewers about the damage hologram display, or the entanglement of the full axis shouting silk I can be a safety issue for people. . The thickness of the pieces 2G.23 and 26·28 can all be about several centimeters, which is lower. The component may contain a color juxtaposition such that the colored light _ such as red, green, and blue = pixels are directed toward the element 22', although if a color light source is used, the color filter does not have to be οτο 22 The infrared organic light-emitting diode array of the organic light-emitting diode array will cause the light emitted by each of the infrared organic light-emitting diodes 24, 200844693 to be parallel, and conform to the light from the only-corresponding color image "X." 23 is an optically-addressed stray lighter, an optical-addressed spatial light modulator, and an infrared organic light-emitting diode array provides a write beam: the color green emitted by the component is a read beam. Tree % Private Line Filter = The transmission of visible light interrupts the infrared light such that the infrared light emitted by element 22 does not affect element 27. Element 27 is an optically addressed spatial light modulator. Element ^ is an array of infrared organic light emitting diodes on the substrate. The infrared organic light emitting diode array will cause each of the infrared organic light emitting diodes to emit light in the direction of the element 27, parallel and conforming to the only corresponding color mixture. Regarding the optically-addressed spatial light modulator 27', the infrared organic light-emitting diode array 28 provides a write beam; the color beam emitted by the element 26 is a read beam. With respect to the transmitted light, the element 23 adjusts the amplitude 'element 27 to the modulation phase. The component 27 can also modulate the amplitude, the component is fading, and the phase is negative. Since the light ray from the infrared organic light emitting diode array on the transparent substrate 28 is incident on the direction of the τ, the element 26 can absorb infrared light. The light of the component 28 is prevented from being optically tuned to the optically addressed spatial light. 23. With such a setting, the light emitted by the two organic light emitting diode arrays 22 and 28 is substantially opposite in direction, ensuring two, spatially-spaced spatial light. The modulators 23 and 27 can be placed in close proximity to modulate the optical localization of the optical space and reduce the optical loss and the pixel crosstalk caused by the beam divergence: when the optically addressed spatial tone The transducers 23 and 27 are in close proximity to a preferred approximation of the non-overlapping propagation of the colored light beams through the optically addressed spatial light modulator. Figure 2 The order of elements 27 and 28 25 200844693 This can be reversed, but this is not considered to be ideal for achieving low crosstalk and high transmission targets between the colored light beams passing through the optically addressed spatial light modulators 23 and 27.

The physical connection G戍' can extend to the larger 26 200844693 area even the entire surface of the layer. The physical connection can be achieved by layer-to-layer bonding, for example by using an optical transfer adhesive to form a compact hologram generation state 15' or by any other means (refer to the outline manufacturing procedure section). ). In Fig. 2, the light emitted by the organic light-emitting diode arrays 22 and 28 is ideally collimated. The light emitted by the fine 'actual organic light-emitting diodes may be light that is not collimated, such as Lambertianx's complete diffusion. When the light emission of the organic light-polar body is not very collimated, the organic light-emitting diode can be as close as possible to the corresponding optically-spaced light. In such a case, the intensity of the incident on the surface of the optical implant will change to the square of the cosine of the human angle. At 45. Or 60. The incident light will result in a intensity that is only two- or - four-quarters of the normal incident light. Therefore, if the organic light-emitting diodes are separated by a sufficient interval, the visible light pixel 総 (4), and the age-near optical tuned light-modulated variability 'geometry effect will lead to traversing the optically-spaced spatial light modulator space. The potential difference generated on the surface is re-localized, even in the case of the organic Wei-two-spreading radiation distribution as the Lange (Μ, the limit case.

In Figure 2 'ideally, the organic light-emitting diode array 22 and 28 The emitted light of 2008 2008693 is quite collimated. However, the light emitted by the actual organic light-emitting diode may be uncollimated, such as the light distributed by Lambertian Xs. When the light emission of the organic light-emitting diode is When not collimated, the geometrical light split of the organic light-emitting diode is modified using a Bragg filter holographic optical element, such as the inner valley described in us '3,670. Bragg filter holographic optical element Causing light collimation' is better than not relying on this component. Figure 8 shows an example of a fabric-like omni-directional optical component. In Figure 8, the (9) is an organic light-emitting diode array, 81 Is a holographic optical element Bragg filter comprising a Bragg plane 'for example a Bragg plane 84, and 82 is an optically addressed spatial light modulator. A single organic light emitting diode in the organic light emitting diode array 80, emitting The distribution of the infrared rays is a distribution as illustrated by 85. The light ray 86' emitted by the organic light-emitting diode array 在 is in the full-image element S1 (4), and then approximately orthogonally incident in the optically-addressed space. In the method 82, the infrared ray which is incident on the optical neutron is 82 can be realized. Another embodiment is shown in Fig. 5. 57 is a illuminating device for providing a planar area. Illumination, and illumination is sufficient to produce three-dimensional images. An example of a large-area image hologram is provided in US 20〇6/25〇671. This device can be used as an example. Lake white In the form of a light-transfer, such as a cold-cathode fluorescent lamp or a light-emitting diode that emits light on a poly(four), system, the 28 200844693 focusing system can be compact, such as a lenticular array or a microlens array. Alternatively, the light source for 57 may be composed of red, green, and blue lasers, or the red, green, and illuminating diodes that emit sufficient coherent light have a non-laser that is sufficiently vacant. Light sources (eg, light-emitting diodes, organic light-emitting diodes, cold-cathode fluorescent lamps) are better. The disadvantages of laser light sources, such as laser spots on holographic reconstruction, are relatively expensive and all Possible safety issues such as the damage hologram showing the viewer or the eyes of the holographic display assembly staff ► Element 57 can contain one or two 稜鏡 optical films to increase the brightness of the display. The contents described in, for example, US 5,056,892 and US 5,919,551. Element 57 can comprise a polarizing element or a collection of polarizing elements. Linear polarizing sheets are one of them. Another example is a reflective polarizer that can transmit a linearly biased state and reflect an orthogonal linearly biased state _ such a sheet > is known, for example, as described in US 5,828,488. Another example is a reflective polarizer that transmits a circularly polarized state, and a sheet that reflects an orthogonal circularly polarized state is known, for example, as described in still (10), 5. Tree 57 may comprise other optical components known in the art of backlighting. The thickness of the jaws 57, 50-54 may all be on the order of a few centimeters or less. Element 51 may comprise a color filter array such that pixels of colored light (eg, red, green, and blue light) are directed toward element S2, although if a color light source is used, the color filter is 29 200844693. An infrared organic light emitting diode array on the substrate. The infrared organic light emitting diode array will enable, for each color pixel, a pair of two infrared organic light emitting diodes that emit only in the direction of element 53 will be flattened and conform to the color pixels from which they correspond. The light emitted. The first type of infrared Z illuminates the side, and the infrared ray of the (four) line first emits a second wavelength of infrared light, and the second wavelength is different from the first wavelength. The element 53 is an optically addressed spatial light modulator. Element % is another optically addressed vacancy view 11. _ wire-type addressing Lang Guangjian H, infrared has a mineral light diode array to provide a human silk; the color yarn emitted by the component 51 is read first. The pre-study address spatial light modulator 53 is two outer and long towels (four)-wavelength (four) emitted by the organic light-emitting diode. The wire-addressed spatial light modulator 53 is insensitive to the two infrared wavelengths of the two-infrared wavelength emitted by the organic light-emitting diode array and will emit the second of the two infrared wavelengths emitted by the organic light-emitting diode array 52. Wavelength transmission. The optically addressed spatial light modulator % is controlled by a second of the two infrared wavelengths emitted by the organic hair lens array 52. The optically-addressed spatial light modulator 54 is invisible to the first wavelength of the _IR long emitted by the organic light-emitting diode array π, or may utilize the absorption and/or wire prevention of the optically-addressed space H 53 - the infrared wavelength of light reaches the optically addressed spatial light modulation Wei 54, by which absorption, in the compact hologram 30 200844693 map generator 55, does not necessarily require an optical addressing space that is insensitive to the first infrared wavelength Fine-tuned H Μ. Alternatively, a single organic light-emitting diode emitting a hetero-phase wavelength may be used. The relative intensities of the two different wavelengths are determined by a parameter such as the voltage across the organic light-emitting diode. Two different wavelengths of radiation can be controlled by time multiplexing. For the transmitted light 'element 53', the element 54 is viewed. It is also possible to modulate her by element 54 such as a vibrating towel*' With such a setting, the organic light emitting diode array 52 emits light having two different wavelengths, ensuring that the two optically addressed* optical modulations 11 53 and 54 can be placed in close proximity to the assay. Positioning the wire: Inter-optical modulation 11 53 and 54 are close to the pixel crosstalk problem that can be caused by less optical loss and divergence of the eye: when the optical address space optical modulator % and Μ are very close, A better approximation of the non-overlapping propagation of the optical spectroscopy optical illuminator. The device located at a point % from the % of the compact hologram generator is some distance 峨 viewer can view the three-dimensional image from the direction of 55. The elements 57, 50, 51, 52, 53 are arranged in a 3-body connection (real connection), each forming a structural-layer, such that the overall material-like object. Physical connections can be direct. Or indirect, fruity thin intermediate layer 'covers the film between adjacent layers. The physical connection can be limited to ensure correct _ mutual _ small _, or can be extended to a larger area 31 200844693 -, even the positive surface of the layer. The physical connection can be achieved by layer-to-layer bonding, for example, by making the line read the axis so that the compact (four) hologram is generated as 55 ' or by any other means (refer to the outline silking order) Part). At the amplitude of the optical positioning of the fine Wei, in a typical setting, the reading of the towel is read by the beam passing through the hybrid polarizer to achieve _= sex bias. The amplitude modulation is controlled by the rotation of the liquid crystal in the applied electric field, wherein the electric field is generated by the photosensitive layer, affecting the polarization state of the light. In such a device, leaving the optically addressed spatial light modulator will pass through another linear polarizer, which can be less intense due to the erratic change of the light, as it is when optically spatially modulating the spatial modulator. In the optical addressing, the brightness correction is recorded, except that they have been in the defined hetero-biased state. In a typical setting, the human-reading optical beam will (four) pass the beam through the hybrid polarizer. Linearly biased. The phase modulation is caused by the 'applying electric field auxiliary riding (four)' field. The electric field is the directional layer, affecting the phase state of the light. In one example of phase modulation, a nematic phase liquid crystal is used, the direction of the optical axis being a constant - but the mineralization is a function of the applied voltage. In the case of phase modulation, ferroelectric liquid crystal is used, and birefringence is fixed 'but the direction of the optical axis is controlled by the applied voltage. In phase modulation implementation, using either of these methods, the output beam has a phase difference for the input beam that is controlled by the applied voltage. 32 200844693 One example of a liquid crystal element that can perform phase modulation is, for example, a redistribution element arrangement in which an anti-parallel arrangement of nematic liquid crystals having positive dielectric directionality is used, as in US 5,973,817. Described content. C. The compact light source is closely combined with the electronic positioning space. This implementation is a close-knit combination of electronically-positioned Lang Guangwei and a full-fledged styling source that produces a three-dimensional image with appropriate illumination. In this embodiment, an electronic address space optical modulator that does not require imaging optics is described as being tightly coupled. This embodiment provides a close combination of a light source or a plurality of light sources, a (four) method, an electronic formula (four) fa_t|| (EAsLM), and an optional 77 light mirror 70. This combination produces a three-dimensional map in the appropriate case. image. In Figure 11 is an embodiment. 110 is a lighting skirt used to provide a flat area of knowledge 'its cap is sufficiently closed to produce a three-dimensional image. 2006/250671 refers to an example of a lighting device that is a large image of a large area image, in which the -_ sub is in Figure 4. The device like nG can be in the form of a white light source array, for example, a cold cathode fluorescent light emitting a white light emitting diode (in the white light emitting diode), wherein the poly (four) system can be compact, such as a lenticular array or micro 33 200844693 Lens array. Alternatively, the light source for 110 may be composed of red, green, and blue lasers, or may be composed of red, green, and blue light-emitting diodes that are sufficiently light. Red, green and blue light-emitting diodes can be organic light-emitting diodes (〇leDs). However, non-laser gauges with sufficient space (eg, light-emitting diodes, organic light-emitting diodes, cold cathode lamps) are more lateral. Laser light_disadvantages, such as the glare-reconstruction of the laser, the expensiveness of the laser, and all the safety issues associated with the damage of the hologram display viewer's eyes to the hologram display device assembly worker's eyes. Element 110 may have a thickness of about a few centimeters or less. In the preferred embodiment, several pieces of 1HM13 will have a total thickness of less than three centimeters to provide a closely spaced, compact source. The το member 111 can be a color filter array such that the pixels of the colored light, such as red, green, and blue light, are directed toward the element 112, which is not required if the color source is too bright. Tree 112 is an electronic neo-space light modulator. Element 113 is a non-essential beam splitter element. The viewer at the point η# from the device including the close-up hologram 115 is able to view the three-dimensional image from the direction of 115. Element 110 may comprise one or two xenon optical films to increase the brightness of the display. Such films are known, for example, as described in still 5,056,892 and us 5,919,551. Element 110 can comprise a polarizing element or a collection of polarizing elements. 34 200844693 Linear polarizing sheets are one of them. Another example is a reflective polarizer, which transmits a linearly biased state and reflects the orthogonal linearly biased state. Such a constraint = is known, for example, as described in US 5,828, the right. Another example is a reflective polarizer that transmits a -plane-biased state, and reflects an orthogonal circle of $biased_ such that Lai is known, for example, as described in use, (8), a%. . Element 11G may comprise other optical elements known in the field of f-light technology. The electronic neon space light modulation H is a kind of spatial light modulation Wei, in which each component in the element array can be electronically addressed. Each element performs some action on the incident light 'for example, to modulate the amplitude of the light it transmits, or to modulate the light it transmits, or to modulate the combination of the amplitude and phase of the light it transmits. . An example of an electronically addressed spatial light modulator is provided in US 5,973,817+, which is a phase modulated electronic addressed spatial light modulator. The liquid crystal electronic type, the fine-grained space 11 is the - side of the electronically-spaced spatial light (4). Magneto-optical electronic addressing (4) __ is an electronic example of positioning light and light ^ another example 0 το pieces no, m, m and 113 are configured as physical connections (real connection), each forming a layer of the structure, making the whole It is a single-, unified-object. Entity connections can be direct. Or _, if there is a thin fiscal layer, cover the film between the adjacent layer 35 200844693. The entity can be closed in a small area of the correct _ recording (4), or can be extended to a large _, or even a layer of silk. The physical connection can be achieved by layer-to-layer bonding, for example (4) using an optical transfer glue to form a compact hologram generator m, depending on how it is used (refer to the Summary Manufacturing Procedures section). Figure 4 is a side view of a conventional technique showing the three focusing elements 1101, 1102, 1103 of the vertical focusing system legs in the form of cylindrical lenses arranged horizontally in the array. The near-collimated beam of the horizontal line source LS2 is exemplified by the unit of focusing element 1102 of the flip unit to the plane 〇p of the spectator. According to Figure 4, many of the line sources are off, and the LS3 is arranged one above the other. The light emitted by each light source is a sufficient space __ in the vertical direction and ^___ in the water direction. This light passes through the transmission element of the light modulator SLM. This is because the elements of the hologram-encoded optical modulator SLM are only diffracted in the vertical direction. The focusing element gland is in the observer plane 〇p with several diffraction stages (only one is useful) imaging source LS2. The light beam emitted by the light source LS2 is an example of a focusing element that passes only through the focusing system. In Fig. 4, the two light beams display a first diffraction order 11〇5, a zeroth order Η%, and a negative-class 1107. Compared to the fresh-point system, the line system allows very high light intensity to be generated. Efficient light intensity can be enhanced by using a plurality of holographic regions that have increased efficiency and arranged for each of the portions of the reconstructed three-dimensional scene. Another advantage is that no lasers, multiple partitions (for example, after a slot that can be part of the shutter) 36 200844693 Common light sources produce sufficient dimming. Usually the 'Full Image display' is used to reconstruct the wavefront in the virtual observer window. The wavefront is what the solid object will produce if it exists. When the observer's eyes linger on a virtual observer in the virtual observer window (v〇Ws), he will see 4 objects. As shown in Figure 6A _, the hologram display consists of the following components: light source, lens, spatial light modulator and unnecessary beam splitter 0 6 to help spatial light modulator and compact display of holographic image The compact combination of the light source produces a 'single-light source and the single-lens of the figure 可由 can be replaced by the _ and the lens array or the lenticular array, as shown in the figure. In Figure 6 ^, the light source illuminates the spatial light modulator And the lens images the light source to the observer plane. The spatial light modulation • til encodes the holographic image and is modulated into the wavefront so that the wavefront can be reconstructed in the virtual observer window. The optional beam splitter element can be used To create several virtual observer windows, such as a virtual observer window for the left eye and a virtual observer window for the right eye. Assuming that the source array and the lens array or lenticular array are used, the light sources in the array must be separated 'Let the light passing through the lens array or the lenticular array of all the lenses simultaneously to the virtual observer window. 37 200844693 The device of Figure 6B is suitable for use in compact holographic displays. This omni-directional display is suitable for mobile applications, such as in mobile phones or personal digital assistants. Typically, such holographic displays will have a screen size of one inch or a few inches. The scale of the screen can be as small as ^1 cm. Suitable components will be described in detail below. 1) A single source of light source/light source array can be used for simple cases. If the observer moves, the observer can be tracked. Adjustments are made so that the resulting image is visible to the observer at the new location. At this point, * is the tracking of the virtual observer window, that is, the tracking is performed in the spatial light modulator followed by the beam pointing component. Sexual image reconstruction. The array of point sources can be used with two arrays.

The configurable array of light sources can be implemented by a liquid crystal display (lcd) illuminated in a backlight. In order to generate an array of point or line sources, only the pixels of the appropriate # are switched to the transfer state. The apertures of these sources must be small enough to ensure that ample space is provided for use with the lenticular array of mirrors. It is preferable to use an organic light emitting diode display as a system. As a spontaneous 38 200844693 light-clothing, most of the light produced by the silker's display will be absorbed by components such as color filters or pixels that are not fully delivered. Closeness and better power saving effect. However, liquid crystal displays may have an overall price advantage over organic light-emitting diode displays, even though organic light-emitting diode displays provide light in a more efficient manner than liquid crystal displays. When the organic light emitting diode is used as the light ray, only the pixels switched to it need to create a virtual observer window at the eye position. The organic light emitting diode display can have a two-dimensional array of pixels or a -dimensional wire. The illuminating area of each point source or the width of each line source needs to be sufficiently small to provide a holographic reconstruction that provides sufficient spatial coherence to the target. Similarly, an array of point sources is preferred for use with lens arrays comprising two-dimensional array lenses. An array of line sources is more suitable for use with a lenticular array comprising cylindrical lenses arranged in parallel. 2) Focusing method: single lens, lens array, money mirror array, poly red image, one light source or multiple wires to observe the pupil plane. If you are very close to the focus tool, edit the two in the space first modulator. ^ is the money thank you W tender - tilt a number of focus elements dry work _ change | | scale jade position can be exchanged. For the close combination of t, the thin focusing tool of the sub-addressing and illuminating, and the _ _ _ _ _ source is a must: the system has a convex _ refraction lens is 39 200844693 too thick. Instead, a diffractive or holographic lens is used. A diffractive or holographic lens can have the function of a single lens, a lens array or a lenticular array. Such materials are present as a surface relief holographic product as provided by Physical Optics Corporation, Torrance, CA, USA. Or use a lens array. The lens array comprises two-dimensionally arranged lenses, each lens being assigned to a light source of the array of light sources. Another option is to use a lenticular array. The lenticular array comprises a one-dimensional array of cylindrical lenses, each lens having a corresponding source in the array of light sources. As described above, if a light source array and a lens array or a lenticular lens array are used, the light sources in the array must be separated such that the light of the lens or the lenticular lens is simultaneously to the virtual observer window. Light passing through the lens array or the lens of the lenticular array is non-transparent to any other lens. Therefore, the hologram coded in the empty ugly red is composed of the sub-full image map. Each of the holograms corresponds to one lens. The hole diameter of each lens must be large enough to ensure that the resolution of the reconstructed object is sufficient. It is possible to use a lens with a full aperture and a full I-picture stone area, as in the example described in 雠_94. That is to say, the aperture of each lens is one or several square meters. 3) Spatial light modulator coding. In general, the coded hologram for the hologram is on the spatial light modulator. 200844693 is composed of a complex two-dimensional _. Therefore, ideally, a spatial light modulator should modulate the amplitude and phase of the local light beam passing through each pixel of the spatial light modulator. However, the 'scenary spatial light modulator can only modulate the amplitude or phase, and cannot be modulated independently. Amplitude modulated spatial light modulators can be used in combination with the tracked phase encoding, such as Burckhardt encoding. Its disadvantage is that it requires a pixel to encode a complex number, and the reconstructed object is less bright. The phase modulation spatial light modulator produces a higher brightness reconstruction. For example, so-called 2-phase encoding can be used, and two pixels are used to encode a complex number. The electronically-addressed spatial view II has the characteristics of side edges which will result in an undesired higher diffraction order in their diffraction pattern, which can be reduced or eliminated by the use of soft apertures. The soft aperture is a hole that does not have a transfer cutoff. a. An example of a soft aperture transmission method is to have a Gaussian pattern. Gaussian graphics are known to be useful for diffraction systems. The reason is that the Fourier transform of the Gaussian function is a fresh result of the Gaussian function itself. Therefore, she transmits with an aperture that is sharply cut off in the transmission pattern itself, and the diffraction of the beam intensity waveform function does not change except for the lateral scale parameter. A Gaussian Transfer _ slice array can be used. When these are provided in alignment with the electronically addressed spatial light modulator aperture, a higher winding with no higher diffraction level or a large reduction is obtained compared to a system with a sharp cutoff in the beam delivery pattern of 41 200844693 Shooting class system. A Gaussian filter or a soft aperture is broken to prevent the diffraction product from being a high spatial frequency. A Gaussian filter or a soft aperture dispenser minimizes crosstalk between the virtual observer windows for the left and right eyes. 4) Beam splitter component group Pixel coded virtual observation S window 2 information

The one or more virtual observer windows in the left eye are limited to the periodic intervals of the Fourier transform of the spatial light modulator encoded information. Using the existing maximum resolution spatial light modulator, the size of the virtual observation (four) window is 1G wire rider. In some cases, this may be too small for applications that are not tracked in the hologram display. The spatial multiplexed virtual = inspector window is the solution to this problem: generating multiple virtual observers. In the case of spatial multiplexing, the virtual observer window is generated at the same time as the spatial light modulator = not _=. This can be achieved by a beam splitter. For example, 1 firstly modulates the information of the _ group of pixels on the H-coded virtual threshold window 1 and the information of the other 2 south. The beam splitter will distinguish between the two groups _ 1 and the virtual observer window 2 will be juxtaposed in the observation 1 and the virtual observer window 2 bay window. Multiplexing can also be used to create the illusion of the left and right eyes without the need for seamless juxtaposition, and there can be a gap between the prospective observer window and the one or more virtual fields for the right eye. It is necessary to be careful that the virtual observer window will not overlap with other virtual observer windows. A simple example of a beam splitter element is a parallax barrier containing black stripes with a transparent area between the black stripes, as described in US 2_23() 49. Another example is a lenticular sheet, as described in Qing Suiqing. Another example of a beam splitter element is a lens array and a ruthenium shield. In the tight full gamut, the treasury is divided into three parts, but a typical 10 mm sized virtual weaver window is only enough to provide a glance, which does not match the average viewer with two eyes and is about 10 apart. Centimeters. However, time multiplex can be used as an alternative to handsome work. In the absence of space multiplex, there is no need to use a beam splitter element. Spatial multiplexing can also be used in the generation of color hologram reconstruction. For space color, work, pixels will be grouped, each group contains red, green and blue color elements. 34 groups are spatially separated in the spatial light modulator, and fine-cut red, green and monitor light. Each-group will be coded for the hologram of the target pair _color_prime. Each-group recreates the color elements of its holographic target reconstruction. 5) Time is more than ji. Under the circumstance, the virtual observation i window will be generated in the same position on the spatial light modulator. This can be achieved by replacing the position of the light source with the simultaneous re-encoding space 43 200844693 light modulator. The money position of the light source must be such that the virtual observer window in the observer plane is seamless and (4). If the time is more than sufficient, that is, the full period is greater than 25 Hz, the eye will see a continuously expanding virtual observer window. Xigong can also be used to create virtual observer windows for left and right eyes. In such a case: there is no need for seamless juxtaposition, and there may be a gap between one or several virtual viewing bay windows for the left eye and one or several virtual observer windows for the right eye. Such multiplexing can be space or time multiplex. ...= multiplex between time and time can also be combined. As an example, three virtual observations are self-contained as spatial multiplexes to create an expanded virtual observer window for an eye. The four expanded virtual viewing windows are time multiplexed to produce an expanded virtual observer view for the left eye and a large virtual observer window for the right eye. Care must be taken that the higher diffraction level of the virtual observer window does not overlap with other virtual observer windows. h Enlarging the multiplexer of the virtual observer window is more recommended than the re-flattening of the spatial light modulator, as it provides an expanded virtual observer g with a continuous change in parallax for observer movement. Simple * words, without re-encoding multiplex, will provide repeated content in the same part of the expanded virtual observer window. 44 200844693 . Xigong is also the best of the Klang County and the Z-, '·, and the slashes of the space. (4)._=:= The score is 6) Undesirable higher winding The processing of the shooting class is as if the larger virtual observer window is a small observer window that is assembled by a smaller virtual observer window, which may cause disturbing crosstalk in other virtual observation windows, unless There are steps to avoid this problem.举— 门 彡 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个 每个The windows overlap. Such overlap may cause the scene to be disturbed. If the unwanted image intensity exceeds the required image intensity by about -5/°~', this will be obvious for the 4 money system. In such cases, it tends to compensate or suppress a higher firing level. If the angle of the illuminated spatial light modulator is constant, a fixed angle filter can be used. This is not the case where the hologram display does not have a tracking function or the beam splitter element (e.g., beam pointing element) is located behind the spatial light modulator. The fixed angle filter can be a Bragg fleler or a Fabry-Perrault gauge (Fabry 45 200844693)

Perot Etalon) In the case of spatial light modulators producing geometrical light intensity distributions with unwanted diffraction levels, Bragg filter imaging optics can be used to correct geometric light intensity distributions [eg, in US 5,153,670 Described content. A Bragg filter holographic optical component can result in a different light intensity distribution than when the component is not used. Figure 7 shows the function of the Bragg filter holographic optics. In Figure 7, % is the spatial light modulation φ 1,71 is a holographic optical element Bragg filter, including a cloth flattening®, such as a Bragg plane 74. A single element 73 on the spatial light modulator 70 provides a diffracted light intensity distribution as shown. Light 76, which is diffracted by spatial light modulator 70, undergoes scattering in holographic optical element 71 and is then transmitted in a different direction than the original propagation between 7 and 71. If the direction in which the light rays 76 are transmitted is between the 70 and 71 is an unwanted first-stage diffracted light, it can be easily seen that the Bragg filter 71 successfully changes the light to a different direction so that it does not cause unwanted and may hinder The viewer's optically processed product, a typical viewer will be located approximately perpendicular to the direction of 70. An adjustable method for suppressing the diffractive class is mentioned in the patent application No. DE 10 2006 030 503. Mentioned is a liquid crystal layer between two coplanar glass sheets coated with a partially reflective coating. For each reflection of the coated beam, the beam is partially reflected and partially transmitted. The interference of the transmitted beam and the phase difference between them will determine whether the interference is constructive or destructive, as changed by the angle of incidence of the beam as described in the Fabry-Perdit 46 200844693 gauge standard. ° Give a wavelength, interference and transmission will follow the light given - the direction of light propagation, the interference can be changed by changing the refraction of the liquid > direction. The refractive index is 3 ΘΒ, and the light is transmitted by the garden to the liquid crystal layer.

control. Therefore, in all the limitations of the Fabry Petrigree gauge, the angular transmission characteristic 曰 can be adjusted, and the diffractive class can be selectively transmitted or reflected as desired. For example, 疋 == 立立_培纹规具 is the most transferred of the slaves and the first class is the most U can still have some unwanted second class and higher class communication. In all the limitations of the Fabry-Perrault gauge, this device can help to set or sequence for a particular diffraction class, or to send or reflect according to demand. Spatial filtering, II can be used in the selection of the diffraction class. The spatial filter can be placed between the spatial light modulator and the virtual virtual observer window and contains transparent and transparent fields. These time-transfers need to be made around the plum level, and I hinder the '+ desired diffracting class. These space_devices can be fixed or configurable. For example, an electronic addressing between the spatial light modulation H and the virtual observer window can be used as a settable spatial filter. 7) Eye tracking In the close combination of the electronic address space light modulator with eye tracking and the close-constrained compact light source, the eye position detector can detect the observer's eye 47 200844693 position. Therefore, one or several imaginary, so that the observation f can, #& can be automatically set in the eye part, the reconstructed object can be seen through the virtual observer window. And: The second demand, the power that affects the performance _, the 縱 其 其 其 其 其 其 其 其 其 其 其 其 其 。 。 No pounds or shells must adjust the position of the monitor automatically. Because of the better real face towel,? d ° to achieve home is not possible is included in the personal digital display of your hand-held display. The number of users, usually used by the library (4), is not used to adjust the virtual observer window to the position of the user's eyes. As we all know, the temple-style device will change the financial position of the device on its own to obtain the most obscure state of the j' as described in wo (4) 6941. Therefore, in the case of the clothes, the user does not need to trace the eyes of the user and is complicated and not as tight as the tracking optics including the scanning mirror. However, eye tracking can be applied to other devices, and for the device, the extra demand for the device and the power supply does not cause an excessive burden. In the case of / after the tracking, the electronic address space light modulator and the full coherence of the tightly coupled light source require a virtual observation window of the domain A to simplify the adjustment of the display. The better virtual observer window size should be the number of eyes of the eye pupil size. This can be done by a single virtual observer window that makes the spacing m light modulation II or a large spacing spatial light modulation (four) number. Recording a small virtual view 48 200844693 Chaba window patchwork. The position of the virtual view window is determined by the position of the light source in the array of light sources. The position of the eye part··_ eye, and the light_position is set to fit the virtual observer window to the position of the eye. S US2006 expands 994 and US2006 should describe the Wei Weiqi trace. Another way (5) When the light source is in a fixed position, the virtual observer window can be privately moved & the light source peach is relatively insensitive to the fine light ray change. If the light source is for moving the virtual observer The position of the window is moved/by; in the case of a tightly touched towel, there may be abnormal light transmission. This setting will make it difficult to close the tight combination of the light source and the spatial light modulator. In such an example, in the 4 display It would be helpful to have a fixed light path and a beam pointing element for the last optical element in the lying device. = + towel gives the beam pointing element. This beam is directed at the element's tow (four) degree in the display. It can have the X and y tracking stellar mirrors and the optical properties of the z_ tracking controllable lens. For example, either or both of the beam directing elements of Figures 20 and 21 can be applied to a single device. The beam pointing tree is a controllable slewing piece of Qianke Lake refracting elements. The controllable refractive reading can include the turning off of the liquid crystal, and the liquid crystal is described as having an isotropic line 49 200844693 Electric dipole electric tensor matrix towel. _ Shape with lens or lens. The electric field controls the effective refractive index of the liquid crystal and helps the beam to be directed. The electric field can vary between elements to produce a beam directing characteristic that varies between elements. As shown in Figure 20, the electric field is applied between the transparent electrodes. The liquid crystal has a uniaxial refractive property and can be surfaced so that the light that strikes it is converted to the refractive index of the main break or "matrix," and the remaining settings can be obtained from conventional techniques. The host material has Isotropic refractive index. If the filament of the liquid crystal is along the z-direction side, as shown in Fig. 20, the appropriate ► electric field application, the plane wave propagating along the Z direction, when it passes through the beam pointing element ^ does not have refraction occurs' Because it does not encounter any refractive index change perpendicular to its wave-forming vector 0 > 〇yntingv_r). Then, if an electric field is applied to the electrode, the optical axis of the liquid crystal is perpendicular to the z-direction, along the z-direction. The meandering plane wave parallel to the optical axis, when it is directed through the beam, will encounter the most refraction, because it experiences the most likely refractive index change along its (system-providable) direction of polarization. The degree of refraction will be adjusted between these two extreme examples by selecting the appropriate electric field applied to the host material. If the cavity is _, the ke is Wei, then (4) can be pointed by the tow. Slightly light The beam points to a suitable prism. If the optical axis of the liquid crystal is aligned along the Z direction, as shown in Figure XX, the appropriate wave field is applied. The plane wave propagating along the Z direction does not have to be directed toward the component through the wire. Refraction occurs because it does not encounter any change in refractive index in its direction of polarization. However, if the electron collar 50 200844693 domain = the liquid crystal axis of the traverse electrode is perpendicular to the z direction, plane wave propagation & The z-direction & is biased parallel to the light secret experience as the most popular because it p-beam & to the TL piece 'because it experiences the most possible refractive index secret to provide a vertical variation of its wave-forming vector ( P-ting vector) If the electric field is applied to the electrode, the optical axis of Wei Jing is perpendicular to the Z direction, and the z-direction is eclipsed (10) flattened when it passes the beam to the element. 'The most refraction will be encountered, _ it experiences the most possible vertical refractive index change of the vertical (10) (system-provided) wave-forming vector (poynting her r). The degree of refraction will be between these two extreme examples, Choose the appropriate electricity to apply in the domain (four)

Field adjustments D 8) The example will then describe an example of an intimate combination of an electronically addressed spatial light modulator with a fully coherent compact Φ-type source that can be produced with appropriate illumination • Two-dimensional images And can be set in a personal digital assistant or mobile phone. The close combination of the electronic space-determining optical modulator and the fully coherent compact light source includes an organic light-emitting diode display as an array of light sources, an electronic address space light modulator and a lens array as shown in FIG. Show. Depending on the location requirements of the virtual observer window (represented by 〇W in Figure 12), a particular pixel in the organic light-emitting diode display is activated. These pixels illuminate the 51 200844693 quasi-continuous electronic address space tones (4) and are imaged by the lens on the observer plane. At least one pixel of each lens of the lens array is activated in the display of the organic light emitting diode crying. The size of the peach age, if the eye is 2 〇 Qing, can be traced to a virtual bribe with a 4 〇 lie increment. The miscellaneous trace is that the organic light-emitting diode pixel is a light source with a partial air. Partial homology produces a fuzzy reconstruction of the target point. In drawing a given size, if the pixel visibility is 20 microns, a target point of 100 micrometers will be generated at a target point of 100 mm from the display. This is the resolution of the human visual system: enough. Through the different lens touches of the lens _, there is no clear symmetry. The need for coherence is limited to each single lens of the lens array. Therefore, the resolution of the reconstruction target point is determined by the pitch of the lens array. For the human visual system, the typical lens spacing would be 1 mm class to ensure full resolution. If the organic light-emitting diode pitch is 20 μm, this means that the ratio of the lens pitch to the organic light-emitting diode pitch is 50:1. If only one organic light-emitting diode is illuminated for each lens, this means that of every 5 〇 λ2 = 2, 5 〇〇 organic light-emitting diodes, only one organic light-emitting diode will be illuminated. Therefore, this display will be a low power display. The difference between the holographic display referred to herein and the conventional organic light-emitting diode display is 52 200844693. The latter concentrates on the viewer's eyes, whereas the latter emits light to 2π steradian. The conventional organic light-emitting one-polarization state realizes a luminosity of about 1, 〇〇〇, (inventor's calculation in practice #)' in practice, the illuminating diode should be able to achieve 1,000 Several times the cd/mA2 luminosity. The virtual observer window is a diffractive class that limits the Fourier spectrum of the encoded information in the spatial light modulator. If the pixel pitch of the spatial light modulator is 〇 ^ ^, and two pixels are needed to encode a complex number, ie if the phase modulation is in the electronically addressed spatial light modulation, she encodes the wavelength at the lake. The virtual observer window will have a width of 10mm wide. Virtual observer windows can be used to piece together virtual observer windows into an expanded virtual observer window, using space or time multiplexing. In the case of space multiplex, additional optical components, such as beam splitters, are required. The color hologram scale can be realized by time multifilament. The red, green, and blue pixels of the color organic light-emitting diode display are successively activated by the holographic change of the red, green, and blue optical wavelengths. The display may include an eye position detector for detecting the position of the observer's eyes. The eye position detector is connected to control the pixel activity of the organic light-emitting diode display. 53 The calculation of 200844693 is preferably performed by an external coded image in the spatial light tone of the hologram ______ The three units produced are executed, and (4) the skills are higher. (4) will be sent to the U.S. image. For practical bribery, (4)-(rtm) e

If: ^ is used for the construction of the red holographic display, the amplitude of the _ hologram = variable coding 'where the county electronic clock damper a4m, the observation window is calculated as L3mm width. • In the case of monochrome, the observation window is calculated to be 4 mm wide. If the same setting is used, but the phase modulation of the 2 phase encoding is used, the observation window is calculated to be 6 mm wide. If the same setting is used, but the phase modulation of the Kinoform encoding is used, the viewing window is calculated to be 12 mm wide. In addition, there are still other high-resolution electronic address space optical modulators. Seiko (RTM) Epson (RTM) Corporation of Japan has published a monochrome electronic address space optical modulator, such as the D4:L3D13U 1.3-inch screen size with a pixel pitch of 15μηι. The company also published the same type of seesaw D5: L3D09U_61G00, with a 0.9 inch screen size and 像素μιη pixel pitch. 54 200844693 On December 12, 2GG6, the company announced the same type of panel L3D07U-81G00, with 〇, 7 inches to screen size and 8 5μιη pixel pitch. If the D4:L3D13U 1.3 correction panel is constructed to display a monochrome holographic display and uses the holographic Burckhardt amplitude modulation coding, the distance is 0.4m from the electronically addressed spatial light modulator, virtual observer The window can be calculated to be 5 6 leg width. D. Close Combination of Paired Electronic Address Space Light Modulators In another embodiment, the combination of two electronically addressed spatial light modulations can be used to modulate the amplitude of the light in a sequential and compact manner. And her. Therefore, a complex number including amplitude and phase can be encoded in the transmitted light pixel by pixel. This embodiment contains a close combination of two electronic neon spatial tones (4). The first electronically addressed spatial light modulator modulates the transmission handle amplitude, and the second electronically addressed spatial filament transformer modulates the transmitted light _ bit. It is also possible to modulate the phase of the transmitted light by the first electronically-spaced optical machine, and the second electronically-defined (four) optical modulator to modulate the Wei Guanglong. Each _ sub-location can be described as in Section C. In addition to the use of two electronic address space optical modulators, the overall configuration can be as described in section C. Any combination of the other two types of electronically located Lange's modulation characteristics that help the amplitude of the independent position is possible. 55 200844693 In the first, the financial, the first - electronic address, such as the paste, use the pattern to change the crying use in the younger brother - step 'the second electronic type of neo-space light; week: code 'to ride the phase _ change. From the second electronically-located spatial light, the amplitude and phase of the light have been modulated. Therefore, when observing the two electronic addresses of the device (four), the light-emitting device is installed. A three-dimensional image was observed. The modulation technique based on the conventional phase and amplitude promotes the representation of complex numbers, and the electronic address space can have a high solution. Therefore, this can be used to generate a hologram to make the _image visible to her. Figure 13 is an embodiment. 13〇 is a lighting device used to provide a flat area of the 'lighting' is a full complement to enable the production of three-dimensional images. A reference to US 2006/250671 is mentioned. An example of a lighting device for a large-area image full-image image, the side of which is shown in Figure 4. The device like (10) can be a white light source array. • Shouting, for example, a miscellaneous county lamp or a hair (four) light person A white light emitting diode on a poly(4) system in which the focusing system can be compact, such as a lenticular array or a microlens array. Alternatively, the light source of the 13() can be composed of red, green, and blue lasers, or The red, green and blue light-emitting diodes are composed of red, green and blue light-emitting diodes. The red, green and k-light emitting diodes can be organic light-emitting diodes (〇LEDs). _, a non-laser light source with sufficient space (eg · LED, organic light-emitting diode, cold 56 200844693 cathode fluorescent lamp) is better. Laser light depends on the shortcomings, such as in the holographic reconstruction caused by = spot, the upper (four) And the _ _ damage hologram shows the viewer or the hologram display device assembler Possible safety issues such as the eyes of a person. The device 130 may comprise one or two optical films to increase the brightness of the display: such films are known, for example, as described in US 5,056,892 and US 5,919,551. The component 130 may comprise a polarizing element or a collection of polarizing elements. A linear polarizing sheet is one of the examples. Another example is a polarizing polarizer that can transmit a - biased state, a neon reflection orthogonal misregistration State _ such thin = is known 'for example as described in us 5, 828, 488. Another example 疋 reflective polarizer 'transmits a circularly polarized state, and reflects the orthogonal circular polarization state... Such a sheet is known, for example, as described in still (10). The element m may comprise a poly(tetra) system, which may be compact, such as a lenticular array or a microlens array. Including other optical components known in the art of backlight technology. - The thickness of component 130 can be on the order of a few centimeters or less. In a preferred implementation, the thickness i of the component 34 is less than 3 cm. Provide adequate A compact light source. Element 131 can be a color filter array such that colored light (e.g., red, green, and blue money (four) trees 132, if the color source is a color source, a color filter is not required. Element 132 is an electron. 57. Address element 133 is an electronically addressed spatial modulo _ element i34 is an unnecessary beam splitter element. For transmitting light, element 132 modulates the amplitude and element 133 modulates the phase. The amplitude is modulated by element B3 and the phase of element 132 is modulated. The proximity of electronically-addressed spatial light modulators 132 and 133 can reduce optical loss and pixel crosstalk caused by beam divergence: when electronically addressed spatial light modulation The devices 132 and 133 are very close to each other, and can be used to record the better recent recording of the non-rereading of the color light of the first light. A viewer located at point 135 some distance from the device including the compact hologram generation 136 can view a three-dimensional image from 136. Reading m, m, mm, and m is a layer that is configured to be physically connected (realally connected)' each forming structure so that the whole is a single, unified object. The physical connection can be direct. Or indirect, if there is a ride (four) layer, the cover is in the phase. The physical continuum _ in the front of her: or, can extend to a larger area, even the entire surface of the layer. The physical connection can be realized by the layer-to-layer complication, for example, the metropolitan area accepts the lion__ to form a compact hologram to generate the crying test summary manufacturing program). 4 疋 Hunting by any other method (in the bun 疋 二 二 二 执行 执行 执行 执行 — — — — — 入射 入射 入射 入射 入射 入射 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 2008 The amplitude modulation is controlled by the rotation of the liquid crystal in the applied electric field, and the applied electric field affects the polarization state of the light. In such a device, the light leaving the electronically-spaced light modulator passes through another linearity. A polarizer that reduces the intensity due to a change in the polarization state of the light, as it does when it is electronically addressed to a spatial light modulator. In an electronically addressed spatial light modulator, phase modulation is performed unless they are already defined. Linearly biased state, in a typical setting, the incident reading optical beam will be linearly polarized by passing the beam through a linear polarizer. Phase modulation is controlled by the application of electricity, which affects light. Phase state. In one example of phase modulation, nematic phase liquid crystal is used, the optical axis direction is fixed at intervals, but birefringence is a function of applied voltage. In the example, ferroelectric liquid crystal is used, the double ride is fixed, but the direction of the wire is controlled by the application. In the phase modulation, the towel is used as the age-of-age method, and the output wire and the input function are applied as a function of voltage. The beam will have a subtraction. One example of a liquid crystal element that can perform her modulation is a Freedericksz element arrangement in which an anti-parallel arrangement of nematic liquid crystals having a positive dielectric anisotropy is used, as in 118. 5,973,817. For close-to-close (four) dense combination, including two, separated or minimal separation methods, the electronic addressing is correct. Her real money is that the two spatial light modulators have the same The number of pixels. Because the two electronically addressed spatial light 59 200844693. Zhou is not equidistant for the spectator, the pixel spacing of the two electronically addressed spatial light modulators may need to be slightly different (but will still be Probably the same), to make up for your doorstep _ for the effect of the observation of the shellfish. The light that has passed through the pixels of the first spatial light modulator will pass through the second spatial light modulator. Therefore, the light is modulated by two spatial light modulators, and complex amplitude and phase modulation can be independently implemented. For example, the first spatial light modulator performs amplitude modulation, and The second spatial light modulator performs phase modulation. Similarly, any combination of the other two spatial light modulator modulation characteristics that are equivalent to independent modulation of amplitude and phase is possible. The light passing through the pixels of the first spatial light modulator can only pass through the pixel corresponding to the first spatial light modulator. If the light emitted from the first spatial light modulator pixel passes through the second spatial light modulator, Crosstalk will occur when corresponding, adjacent pixels. These crosstalks may cause problems with reduced image quality. Here are four possible ways to minimize crosstalk between pixels. It is obvious by conventional techniques. 'These methods can be applied equally to Part B embodiments. (1) The first and easiest way is to directly adjust the two spatial lights after adjusting the pixels to be connected or bonded together. In the pixels of the first spatial light modulator, there may be a diffraction phenomenon that causes the light to deviate from propagation. The separation between the spatial light modulators must be sufficiently thin, as thin as the crosstalk between adjacent pixels of the second spatial light modulator reaches an acceptable level of 200844693. For example, the spacing of two electronically addressed spatial light modulators with a 1Q _ image distance must be less than or equal to the level of 10_100μηι. This is almost impossible to achieve in the transmission of the spatial light modulator, because the thickness of the glass cover is a level of lmm. Of course, the "sandwich" method that enables the thinness of the space between the thinners to be separated is a reduction in the -health #巾. The manufacturing method of the part of the program can be used to make a device containing two or less small or small electronic address space light modulators. Figure 14 shows the Fresnel diffraction data graph calculated by the diffraction of the slit 1 〇 μπι wide, changing the distance from the slit in the two-dimensional model, the vertical axis is slit(z), and the horizontal axis is slit (x). The uniformly illuminated slit is located between -5 μm and +5_ on the x-axis and Ζ is zero microns. Optical transmission media are used to obtain a refractive index of 15, which is a typical medium for compact devices. The selected light is red light with a vacuum wavelength of 633 nm. The green and blue color wavelengths are smaller than the red light, so for the calculation of red light, the strongest diffraction effects are exhibited in the three colors red, green, and blue. You can use parametric TecMology (RTM) €〇φ” Needham, Hidden, USA's product M (5) (RTM) software to perform calculations. Figure 15 shows that the slight intensity is left in the center of the slit ΙΟμιη wide, for the narrow The function of the seam distance. Where the distance from the slit 2〇_, Figure 15 shows that the intensity greater than 9〇% is still in the range of 1〇μιη wide of the slit. Therefore, in this two-dimensional model, less than 5% The pixel intensity is incident on each adjacent pixel. This is the result of the limitation of the zero boundary width between pixels. Actually, the boundary width between pixels is greater than zero, so the crosstalk problem is real. The system will be lower than the result of ##. In Figure 14 towel, Fico's diffraction pattern is close to the slit, for example 50μπι from the slit, and is somewhat similar to the high-hat strength function of the slit. The diffraction characteristic of 觅 is close to the slit. The wide diffraction characteristic is the L # of the high-hat function, and the 4-inch property of the % injection function. This is the sinc square (j function) which is commonly used. The sign can be from the distance slit 3〇〇μιη in Figure 14. The example is observed. This indicates that the diffraction effect can be closely controlled by setting the two electronically addressed spatial light modulators close enough and that the two electronically addressed optical modulators are placed very close together. One advantage is that the functional pattern of the diffracted data graph changes from a far-field characteristic to a more efficient function that contains light that is close to the axis perpendicular to the slit. This advantage is contrary to the idea of the conventional imagery technique. The technique tends to think that when the light passes through the small aperture of the spatial light modulator, it will cause strong, large and unavoidable diffraction effects. Therefore, the conventional technology does not have to bring two spatial light modulators closer. Together, the motivation is expected to result in a pixel crosstalk problem that must occur and is severely caused by the diffraction effect. Figure 16 shows a contour plot of the intensity distribution, the intensity distribution as a function of the distance from the slit. The plot of the line is on the logarithmic scale, not the linear scale. Ten equal-twist lines are used, all including a range of 100 intensity factors. For a slit width of 10 μm, strong A large degree of boundary is clearly defined in the range of approximately 50 μm from the slit. 62 200844693 In an advanced embodiment, the pixel aperture of the first electronically addressed spatial light modulator can be reduced to mitigate The second electronically-spaced space is used to adjust the crosstalk problem of Wei. (2) The second method is to use a lens array between two spatial light modulators, as shown in Figure 17. The better method is to let the lens The number of pixels is equal to the number of pixels in each spatial light modulation. The distance between the two spatial light modulation H and the distance between the lens arrays can be slightly different to compensate for the distance difference of the observer. The pixel of the light modulator is on the pixel corresponding to the second spatial light modulator, as shown in Figure 17 of the big money bundle Π1. It is also possible that light will cause crosstalk problems through adjacent lenses, such as a large number of beam Π2 solutions. If its intensity is _low, or if its direction is sufficiently different to make it impossible to reach the virtual observer window, it will be ignored. The numerical aperture (NA) of each lens must be large enough to image a pixel with sufficient resolution. As an example, for a fine resolution, an aperture of approximately 0.2 峨 is required. This also means that if it is assumed that the optical distance between the lens array and the lens array is 1 〇 μηι, the maximum distance between the lens array and each spatial light modulator is about 25 μm. 63 200844693 It is also possible to assign a number of pixels of each spatial light modulator to one lens of the lens array, taking a group of four pixels of the first spatial light modulator, which can be used by the lens array. A lens is imaged into a second spatial ramper by a group of four pixels. The number of interrogation lenses will be four quarters of the number of pixels in each space. This allows the use of lenses with higher numerical apertures, thus resulting in higher resolution imaging pixels. (3) The third method is to reduce the pixel aperture of the first-electronic address stray modulator as much as possible. From the viewpoint of diffraction, the area of the second spatial light modulator illuminated by the deleted pixels of the first spatial light is the pixel width D and the age of the first electronically-positioned spatial light modulator. The decision is as shown in pin eight. In Figure 18, the distance between the two electronically-spaced spatial light modulators, and w is the distance between the two first-P-level diffraction minimums, which occurs in the zeroth class maximum. One side. This is assumed to be a fine and fierce (F_hGfe_ shot, or a reasonable approximation of the Fraun and Fiji diffraction. Reducing the aperture width D - square © can reduce the range of direct projection of the new area of the frame" In the other way, according to the diffraction angle, the diffraction angle is proportional to the ι/d ' in the shot, and the ι/d ' in the shot is increased. This increases the fineness n in the second electronic address space. The width of the width of the read area is w. In the Fraun and Fis diffraction methods, the division d, D can be determined, and the program W = w in the diffraction of 64 64 44 44 44 is used to minimize w. The equation is derived from the distance between the two first-order minimums of Fraun and Fiji. For example, if 縦0.5, d is m and w is the minimum value of m, but f. However, in this example, The Frang and Fiji methods may not fit together a good approximation. This example has the principle of making the distance between the sub-addresses of the clock-modulated I to control the diffraction process in the Fraunhofer diffraction mode. The _ four methods use a fiber optic panel to image the illuminator to the pixels of the second space. The panel is composed of two parallel columns of parallel precursors. The length of the light_length and therefore the thickness of the panel is typically a few shame, and the diagonal length of the panel surface is as long as several inches. For example, the spacing of the fibers can be 6 division. Edmund 0ptics Inc.〇f B, as for n, ^ knows the kiss with the fiber-optic panel of the first _ distance. Each fiber is guided from its - ray bow to the other end. Therefore, in the panel - The image of the end will be transmitted to the other end, and there is high resolution and no focusing component. Such a panel can be used as a separation layer between two spatial light modulators, as shown in the pin 9. The recording is better than Single mode fiber, because the multimode light_fresh axis is good in single mode domain. When the (four) rate of the first _ heart is consistent with the refractive index of the liquid crystal, the best efficiency is obtained. (4) This can minimize the non-/ The back of the ear is reflected by the reflection. 65 200844693 There is no money outside the two kinds of miscellaneous light. The polarizer, the electrode: the alignment layer is directly connected to the fiber optic panel. Each of these layers is very thin, that is Level 1-1_. Therefore, liquid crystal (LQ layer La and LC2 are in the vicinity of the panel. By the first - The light of the inter-optical modulator pixel is directed to the pixel corresponding to the second spatial light modulator. This minimizes the adjacent pixel (four) sound. The panel transmits the light distribution of the _ spatial light-modulated Wei output to the second spatial light tone The input of the transformer. On average, 'each pixel should be at least one fiber. If each pixel is less than - one fiber, 'on average' the spatial light modulation will lose the resolution, resulting in display in the hologram display. The image quality of the applied application is reduced. In Figure 19, the spatial spatial modulator modulates the amplitude, and the second spatial optical modulator modulates the phase. Other electronically addressed spatial tones that lack complete complex modulation The combination of the modulation characteristics of the transformer is possible. Figure 10's shows an example of the tight alignment of the amplitude and phase information of the image of the image. 104 疋 (4) U is used to provide illumination of a planar area where the illumination is sufficiently homogenous to enable the creation of a three-dimensional image. An example of a device for large area image hologram is mentioned in us 2006/250671. A device such as a 1G4 may be in the form of a white light source array, such as a white light emitting diode on a focusing system, such as a luminescent lens, wherein the poly (tetra) system may be compact, such as a lenticular 66 200844693 array or micro. The lens array is moving. Alternatively, the light source used for the operation may consist of red, green and blue lasers, or a full-color red, green and blue light-emitting diode. However, a non-laser light source (10) having a sufficient m and the same type, such as a light-emitting diode, a light-emitting diode, and a cold cathode lamp, is more (four). The shortcomings of the laser ray, such as the glare of the holographic reconstruction, the more blame on the slap and all the safety issues such as the hologram of the injury showing the viewer's eyes and the eyes of the holographic display device group. Element 104 may comprise one or two xenon optical films to increase the brightness of the display: such films are known' as described, for example, in us 5, (d), 892 and us 5, 9i9, 55i. Element 104 can comprise a polarizing element or a collection of polarizing elements. Linear polarizing sheets are one of them. In addition, an example is a reflective polarizer, which is capable of transmitting a hetero-biased state, and is known to reflect orthogonal hetero-biasing, such as that described in U.S. Patent 5,828,488. Another example, the sub-reflective polarizing >; 'Wei-side-biased state, and reflecting orthogonal circles, secret state - such a sheet is known, for example, in us 6, (8), 395 Described content. Element 104 can include other optical components known in the art of backlighting. The elements 104, 100-103 #all may be on the order of a few centimeters or less. The component may include a color filter, such that the pixels of the peach light (e.g., red, green, and blue 67 200844693 shades) are directed toward the component 1〇2, although if a color light source is used, the color overshoot is not required. Το件1〇2 is an electronic address space optical modulator that encodes phase information, such as Freedericksz components. Element 103 first encodes the electronic address space of the amplitude information, for example, in a commercially available liquid day and day display I. Each element of the element 102, here, will be labeled, and will be represented by the corresponding element arrangement in the element 〇3. However, in spite of the elements in elements 1〇2 and 1〇3 and having the same lateral spacing or spacing, the element size in element 102 will be less than or equal to that of component 103 in the component 103. The elements 108 of the component (10) typically undergo some diffraction. The order of encoding the amplitude and phase can be reversed as shown in Figure 10. The locator 106 is located at point 106 from the apparatus including the compact hologram generator 105 - the distance viewers can view the three-dimensional image from the direction of 1G5.

As shown in Figure 24, the close combination of the inductive and the compact source of the charging side includes an external optical modulator and lens array. The spatial light modulator in Fig. 2, the package contains = or two pairs of organic light-emitting diodes and the combination of space-type light modulators = one or two electronically-addressed spatial light modulators Tightening, or -: There are: a combination of illuminating-polar body and optically-addressed spatial light modulators and a seven-space spatial light modulator. In a simple example, the array of light sources can be formed in the following manner. A single light source, such as a single-color light-emitting diode, is placed in close proximity to the aperture array so that the aperture can be illuminated. If the aperture is a slit of a one-dimensional array, the light that is transmitted from the slit is a one-dimensional array of light sources. If the aperture is a circle of a two-dimensional array, the illumination set I of the circle forms a light source of a two-dimensional array. A typical aperture width will be approximately 20 μm. Such an array of light sources is suitable for use in the production of an observer window at a glance. 69 200844693 In Figure 14, the 'light source array is dislocated at a distance from the lens _ U. The light source _ can be a picture-cultivation 1 (four) light source, and optionally includes a touch-of-graph 11 of the figure. Specifically, each of the light sources in the array of light sources is located at a distance from the lens U corresponding to 匕 in the train. In a preferred embodiment, the array of light sources is parallel to the plane of the lens array. The spatial light modulator can be located at the end of the 'j'. The distance between the virtual observer window and the lens array is u. The lens in the lens array is a concentrating mirror, and the focal length f is given by f = 1 / [1/u + 1 / v]. In a more preferred embodiment, the value of V is in the range of 300 mm to 600 mm. More preferably, the 'v is about 4 mm. In the preferred embodiment +, the value of ^ is in the domain of _ to 3 Gmm. In a more preferred embodiment, u is approximately faceted. The amplification factor is determined by v/u.乂 is the source of the light source modulated by the spatial light modulator, which is amplified by the virtual observer. In a preferred embodiment, the value of Μ is in the range of 1 〇 to 6 。. In a more preferred embodiment, Μ is approximately 20. In order to achieve such an amplification factor and have a good holographic image quality, an accurate arrangement of -wire_and lens_ is required. In order to achieve accurate _, and maintain a distance of _ between the array of light sources and the lens _ until the component's useful life is exceeded, the device components need to have strong mechanical stability. The virtual observer window can be traceable or untrackable. If the virtual observer window is traceable, the particular light source in the light source array will be activated depending on the desired position of the virtual observer window. The activated light source illuminates the spatial light modulator, 200844693 and is imaged by the lens array to the observer plane. In the array of light sources, at least one light source is activated for each lens that is transmitted through the array. Tracking is quasi-continuous. If u is 20mm and V is 40〇mm, if the pixel pitch is 2〇μιη, the virtual observer window with 4〇Ομηη lateral increment can be traced. Lai’s pursuit is quasi-continuous. If u is 20mm and ν is 400mm, f is probably i9rmn. The light source in the array of light sources may only have partial spatial homology. Partial homology leads to fuzzy reconstruction of the target point. If the mouth is as the face and ν is the axis, if the source is wide, the reconstruction of the target point of the shirt and the coffee will have a 〇 _ _ _. In the human visual system, _ resolution is sufficient f does not need to have any obvious mutual brood between the light passing through different lenses in the lens array. The same needs of the chicks are for each single lens of the lens towel. Therefore, the resolution of the reconstruction target point is determined by the pitch of the lens array. The eight-to-one lens will be rated at 1mm, and the bribe will be fully resolved for the human visual system. / View 7 stomach view _ limited to the space light to adjust the information of the dragon towel code of the Fourier frequency "a diffraction class. If the pixel spacing of the spatial light modulator is a melon, parallel, flat code, at a wavelength of 5 〇〇 nm, the virtual observer 71 200844693 window will have a K) face width. The fun window can be slashed or time multiplexed' to piece together several virtual observer windows into an expanded virtual observer window. In the case of additional optical components, such as beam splitters. In the second case of the implementation of the case, "there are some multiplexed methods. These multiplexed methods may also be applied to the zero-color hologram in this article." _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ m color and blue = ^ pico # full image _ space _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The control unit of the light source movement in the fine period is the control unit of the light source moving in the fine period. The calculation of the hologram image encoded on the space light modulator is preferably performed by the external code as early as it is required to record the Takasaki calculation ability. The #料 will then be sent to the personal digital assistant or line to display the three-dimensional image produced by the full image.

If the same setting is used, but use the 2-phase ___ variable 'observation window' according to the calculation for 6 Cong Kuan. If the same setting is used, but the Kinofbrm encoding __ is used instead, the viewing data is calculated to be 12 mm wide. There are still other high resolution electronic address space light modulators. Seik0 (RTM) Epson (RTM) Corporation of Japan Space Light Modulators such as the D4: L3D13U U-Time Panel with a 15μm pixel pitch.

On 12 S 12, 2006, the company announced the same type of panel L3D07U-嶋〇, with a 7-inch screen size and a pixel pitch of 8 5 cm. If the D4:L3D13U U-pair panel is used to construct a monochrome holographic display and uses the holographic Burckhardt amplitude modulation code, the distance from the electronically addressed spatial light modulator is 0.4m. The virtual observer window can be calculated to be 5 6mm wide.

This is wide enough for an eye. For the other-eye second virtual observer, it can be established by spatial or temporal multiplexing by the content of the wild space light modulator. In the absence of tracking, in order to see the best 3D image, the observer must rotate or * _ device and / or his own position, so that his eyes can be in the virtual observer window "and located in the best device the distance. Several virtual observations can be made in a way that makes it easier to adjust the position and orientation of the display device. Two or three virtual observer windows can be juxtaposed in the x_ and direction so that the virtual inspector window can cover a larger area. The way to piece together can be done by space or time multiplexing, or a combination of space and time multiplexing. In the time-to-work, Lu Lu is projected into the virtual observer window in time. If the virtual observation window has a different _ content, the spatial light adjustment Wei must be re-edited. In the space, for the content of different virtual observation S windows, Du is the same time in the spatial light modulator, but in the different areas of the spatial light modulator. The beam splitter splits the light in different areas of the spatial light modulator into different virtual observer windows. A combination of space and time multiplexing can be used. 76 for hand-held three-display devices typically used for mobile phones _ number of assistants 2008 2008 693 full-image display of colorimetric images, for example by displaying the same two-dimensional image age device can switch the display of two images to the viewer An embodiment of a three-dimensional image display device comprising a pair of - or - an organic light-to-bright light modulator combination or a face-to-face two-dimensional address space combination.

In the two-way three-turn image, the machines 33 and 34 record the user's right and left eye images, respectively. The data obtained from these images will be used to create a 3D image on a handheld device corresponding to the same.

Auto-stereoscopic or holographic display using a combination of one or two infrared organic light-emitting diode displays and an optically-addressed spatial light modulator. 200844693 Infrared organic hair #One-pole display and optical The closeness of the address space optical modulator (such as the one described in Part A) can also be used in auto-stereoscopic displays (ASD):, especially in mobile phones or personal digital assistants. ,,,,,,, (4) In the case of a flipped viewer, viewing an autostereoscopic display is not as comfortable as viewing a full-image display. In an off-state, an autostereoscopic display may be cheaper than a full-image display. Or it is easier to generate or provide image data. The autostereoscopic display provides several viewing areas, and each viewing area ► field displays different views of the three-dimensional scene. If the viewer's eyes are in different viewing areas, he You will see a stereoscopic image. The difference between autostereoscopic display and holographic technology: Autostereoscopic display provides two flat images, while omnidirectional technology provides each target point in a 3D scene. Z-information. The auto-stereoscopic TFll is based on the spatial multiplexing of the viewing area on the display || and uses photo-distributing elements such as lenticulars, obstacles, masks such as masks or It is the masking surface (four). Obstacle cover also: It can be called "parallax barrier". A disadvantage of autostereoscopic displays is that the resolution of each viewing area is typically inversely proportional to the number of viewing areas. However, this disadvantage can be compensated for by the advantages of the autostereoscopic display as described above. The close combination of an infrared organic light-emitting diode display and an amplitude-modulated optically-addressed spatial light modulator (as described in Section A) can be used to make an amplitude-modulated display with a breadth of 82 200844693 2 .

The Auto 2 display consists of a beam splitter and an organic light-emitting diode array, which may have a garnish due to the organic-emitting diode of the pattern, for example: fish organic light-emitting diode during the beam splitter _# Effect (M coffee effeets). In contrast, in a tightly combined optical address such as a light-emitting device (four), it is _: only during the beam splitter, periodic processed products do not appear. The light source of the autostereoscopic display H can be one or more light sources, such as a light emitting diode, a laser, an organic light emitting diode or a cold cathode fluorescent lamp. Silk does not need to be homogenous. If an organic light-emitting diode is used and the autostereoscopic display displays a color image, a color filter layer, such as red, is required between the light source and the light-emitting display and the tightly-adjusted optically-addressed spatial light modulator. Green and blue transitions. 83 200844693 The close combination of an infrared organic light-emitting diode display and an optically-addressed spatial light modulator (such as described in Part A) can also be used in holographic displays, especially when it is used to activate a telephone or personal digital assistant. Handheld display in the middle. A holographic display is based on spatial multiplexing of the viewing area on the display, and uses photon spectroscopy, brilliance elements such as lenticulars, obstacle masks for red such as brittleness, or prism masks. ). Obstacle masks can also be called "parallax barriers". Infrared organic light-emitting diode displays and optically-addressed spatial light modulators can be used to become (for example, what is described in Part A) A high-resolution image of the king,,, and page shows that if the close combination of the infrared organic light-emitting diode display and the amplitude-modulated optically-addressed spatial light modulator is combined with the beam splitter element, then it can be constructed. Produces a high-resolution holographic display. The high resolution of tightly combined compensation compensates for the loss of resolution due to spatial multiplexing. In another embodiment, two pairs of organic light-emitting diodes _ and optically addressed spatial light The tightly combined group u of the transformer can make the amplitude of the twilight change light in a sequential and intimate manner, as described in section b. Therefore, the complex number consisting of amplitude oil levels can be imaged one by one. The way of the element is to transmit the light towel code. If the close combination of the two pairs of infrared organic light emitting diode displays and the amplitude of the female optical address space is changed with the beam splitter element, I Ke Wei has a high resolution.

Next, the data on the two-dimensional image and the depth map is transmitted to the device of the user 221 via the connected milk. The user 221 device encodes the hologram based on the received two-dimensional image and depth map in its compact three-dimensional display device. In order to efficiently use the information transmitted in the system towel, the conventional compression program can be performed and the touchdown is performed on the receiving device. The most efficient amount of data compression is the cost of compressing and decompressing the battery of the mobile device compared to the bandwidth requirement for using less data compression. The intermediary 224 can access a library containing a collection of known three-dimensional shapes and attempt to stabilize the three-dimensional (four) pairing it computes, or it can access a library containing a collection of known two-dimensional graphics, and Pairing the two-dimensional image data that is steadily entering in its towel. This can speed up the calculation of the program if the pairing is made in a known shape' because the two or three image can be represented as corresponding to the known shape. The library of three-dimensional shapes can provide, for example, the face or body shape of a group of stars, such as a major tennis player or a Wei athlete, and all or part of a major sports venue, such as the famous _Campus_ is a famous football field. For example, a three-dimensional image of a human face can be represented as data that has been accessed by an intermediate device 224, plus facial expression changes, such as smiling females, plus changes in hair length, because ° is possible after the age of the data (4) Or cut short.

Finally, the software that performs the calculation will only need the computer on the strip network to be installed in the viewer's three-dimensional display device. This will reduce the need for the viewers to view the axis and the scope of software piracy, and will add any corporate secret code to the private code. Most of the three-dimensional image display of the axis can be performed by the intermediate system. However, it is also possible that some of the images are executed in the viewing surface three-dimensional display device. The three-dimensional image display device may perform a plurality of image leaflets, such as decompressing the compressed image material, or generating a holographic image of the spatial light modulator from the two-dimensional image and its corresponding depth 11. • In an example, the intermediate system can use the 4-wire sequence between the 2D and 3D images to calculate the corresponding depth map of the received image.

In addition, the holographic display can be as described in A' B 'C or Part D, or any full-image display for f. ~ Several observer windows, such as a left-view virtual observer window and a virtual observer window for the right eye, can be generated by space or time multiplexing. With regard to spatial multiplexing, two virtual observer windows are generated at the same point in time and are distinguished by a beam splitter, similar to an autostereoscopic display, as described in WO _27228. Depending on time, the virtual observer window is generated in time. The hot direction, the conventional holographic display system has "Na Tian." Cong space is multiplexed and Lu's riding photo (four) is empty in the horizontal direction, and is based on the horizontal line light source and lenticular array, as shown in Figure 4 by the conventional technology touch 2006/0. This has the advantage that the known technology of the autostereoscopic display can be achieved. However, its shortcoming is that the holographic reconstruction in the horizontal direction is incapable of replacing the uni-dimensional code, producing only the eigenweight b and the moving parallax in the vertical direction. Thus the 'vertical focus' is on the plane of the reconstructed object and the point is on the plane of the (four) light modulator. These astigmatism reduces the spatial visual: f, meaning that it reduces the quality of the holographic reconstruction of the viewer's (4). _ 地, 时 92 200844693 The multiplex system also has the lack of fast-space optical modulation points, which need to be available in all display sizes, and it is too expensive to get instantly. Again - the secret code provides full-image reconstruction in the horizontal and vertical directions (4), so == will not produce _, astigmatism will reduce the empty _ product #, which means that the actor's hologram is reduced. The purpose of this real side is to combine the one-dimensional coding to achieve spatial multiplex of virtual observer windows. In this real scarf, the illumination with horizontal non-straight locality is combined with the beam splitter, which splits the light into light for the left-eye virtual observer and for the right eye. Therefore, the diffraction at the beam cutter must be considered. The beam splitter can be a prism array, a second lens array (e.g., a static array or a variable array, as shown in Figure 20) or a barrier mask. An example of this embodiment is shown in Figure twenty-fifth. Figure 25 is a schematic diagram of a holographic display comprising a light source of a two-dimensional array of light sources, a lens of a two-dimensional lens array, a spatial light modulator, and a beam splitter. The beam splitter splits the light exiting the spatial light modulator into two beams that illuminate the virtual observer window (VOWL) for the left eye and the virtual observer window (VOWR) for the right eye. In this example, the number of light sources is one or more; the number of lenses is the same as the number of light sources. 93 200844693 In this example, the beam splitter is behind the spatial light modulator. The positions of the beam splitter and the m-light modulation n can also be exchanged. Figure 26 shows this example _ sub, in the flat _ + is to make the ray mirror _ as a beam splitter. The illumination device comprises a two-dimensional array of light sources (LS1, LS2, ... LSn) of n elements and a two-dimensional lens array (L1, L2, ... Ln) of n elements, only two light sources are shown in Figure 26 With two lenses. Each system is the lens it closes to image to the observer plane. The light source _ 距 鳞 _ _ 关 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In Figure 26, the left-eye virtual observer window (VOWL) and the right-eye virtual observer window (VOWR) are not displayed because they are outside the figure and are on the right side of the figure. Additional field of view lenses can be added. In order to provide a blank, the spacing of the lens array is similar to that of the sub-holomorphic image, that is, to a few millimeters. Illumination is horizontal and perpendicular to each lens , because it is small or a point source' and because a two-dimensional lens array is used. The lens array can be refractive, diffractive or holographic. In this example, the beam splitter is a one-dimensional array of vertical prisms. The light incident on the prism-bevel will be deflected to the left-eye virtual observer window (t〇v〇wL), incident on the prism and another oblique _ light, which will be skewed to the right eye virtual _ inspector window (9) VOWR) . Light rays generated from the same Ls and the same lens are also phase-adjusted after passing through the beam splitter. Therefore, it is possible to have a two-dimensional coding of the vertical moving parallax with vertical and horizontal focus sisters vertical with water 94 200844693. The hologram is performed on a spatial light modulator with two-dimensional code. The hologram for the left and right eyes is a block-interlace of the blocks, meaning that the sheds are erroneously coded for left-eye and right-full-image information. It is better to have a block for the left-eye hologram information and a shed for the mine-wide image information. Another method 'can also have two or more hologram traps under the slope of each prism', for example three seats for the left eye virtual observer window, and then three for the right eye The establishment of a virtual observer window. The distance between the beam splitters may be the same as the spacing of the spatial light modulators, or an integer (eg, two or three) multiples, or, in order to allow for perspective sh〇rtening, the beam splitter spacing may be spatially lighter The change ||_ is slightly smaller than the point, and the integer is slightly smaller than the integer (for example, two or three). Light emitted from the block with the full image of the left eye reconstructs the target for the left eye and illuminates the virtual observer window of the left eye (V〇WL); the light emitted from the block with the full image of the right eye is reconstructed for the right eye The target and illuminate the virtual observer window of the right eye. Therefore, each eye will see an appropriate reconstruction. If the pitch of the prism array is sufficiently small, the eye cannot resolve the prism structure and the prism structure does not interfere with the reconstruction of the hologram. Each eye will see a reconstruction with full focus and full motion parallax, and no astigmatism. 95 200844693 There will be diffraction on the beam splitter' because the same dimming will illuminate the beam splitter. The beam splitter can be regarded as an age grating that produces a township rewinding profile. Oblique prism The bevel has the effect of a _-type grating. For a clear grating, the maximum intensity is directed to a particular winding stage. For _ mirror _, - one of the singularity self-dip prism

The bevel guides the diffractive class at the virtual observer's window position of the left eye, and the other maximum intensity is directed from the other bevel of the prism to another diffractive class located at the virtual observer's position of the right eye. More precisely, the maximum intensity of the envd〇ping sinc_sq_d function is moved to these positions, and the Wei-ray class is in a fixed position. The prismatic array is generated at the position of the left-eye virtual observer window—a strength package smc_SqUared function maximum value' produces another intensity-insensitive Sine_sq_d letter field at the position of the right-eye virtual observer window. Its recording _ degree will be small (meaning that the maximum sine squared intensity function is narrow) and will not cause interference crosstalk because the fill factor of the prism array is large, such as close to 黯. . As can be seen in the prior art, in order to provide a virtual scout window to two or more observers, a more complex prism array can be used (eg, two types of prisms have the same apex angle, but different non- The degree of symmetry, continuously adjacently configured/generating multiple virtual viewing windows. However, using static prisms _ is to track observers individually. " 96 200844693 In another example, more than one light source can be used per lens. Additional light sources for each lens can be utilized to create additional virtual observer windows for additional spectators. This is described in WO 2004/044659 (US2006/0055994), providing a lens for m spectators An example of m light sources. In this further example, m light sources per multiplex and double spatial multiplexing are used to generate (5) left virtual observer windows and m right virtual observer windows for m observations; M. Each lens m light source is in m-to-correspondence, where (10) is an integer. Next is an example of this embodiment. Using a 2 inch inch ruler Inch, and has the following parameter values: · Observer distance 2m, pixel spacing is 69 in the vertical, 207μπι in the horizontal, using Burckhardt encoding, and optical wavelength 633nm. Bookhart ( Burckhardt) code is in the vertical direction, with a sub-pixel spacing of 69 qing and a virtual weaver window of η high (vertical period). Ignore the perspective shortening, the vertical prism array spacing is 414μηη, that is, in each full prism There are two space light modulators. Therefore, the horizontal period in the observer plane is 3mm. This is also the width of the virtual observer window. This width is smaller than the ideal pupil of the eye about 4mm in diameter. In another similar example, if the spatial light modulator has a smaller pitch of 50 μm, the virtual observation f will have a width of 25 coffee. 97 200844693 If the adult eye is separated by 65 mm (this is typical), the prism The light must be deflected by 32.5mm, at which point the light will be the same as the plane containing the virtual observer window. More precisely, the intensity package has the maximum value of the sine-squared function. To be skewed by 32.5mm. This is equivalent to the angle of the gentry 93 for the observer distance of 2m. For the prism refractive index η = 1.5, the appropriate prism angle is soil 186. The prism angle is defined as the base and prism oblique The angle between the sides. For the horizontal period in the observer plane of 3 mm, the position of the other eye is at a distance of about 21 diffraction stages (ie 65 mm divided by 3 mm). Higher diffraction by another virtual observer The crosstalk between the virtual observer window in the left eye and the virtual observer window in the right eye is thus negligible. To implement tracking, the light source is tracked as a simple tracking method, meaning to adapt to the position of the light source. If the spatial light modulator is not on the same plane as the prism array, 'between the spatial light modulator pixels and the prism, there will be a disturbing related lateral offset caused by the parallax. This will probably cause disturbing crosstalk. In the above example, the pixel size of the screen may have a fill factor of 70% in the direction perpendicular to the axis formed by the tip of each prism, that is, on each side, the pixel size is 145 μm. 31 Qing has no effect on the area. If the construction area of the prism array is tuned to the spatial light, the separation between the prism array and the spatial light modulator may be approximately 1 mm. The horizontal tracking range without crosstalk will be 3 丨μιη /丨* 98 200844693 2 m = soil 62 mm. If small crosstalk is tolerable, the range of tracking will be larger. This tracking range is not very large, but it is enough to allow some tracking to occur, so that the viewer will have fewer restrictions, such as limiting the placement of his/her eyes. The parallax between the spatial light modulator and the prism array can be avoided. The better way is to integrate the prism array or directly integrate it into the spatial light modulator (such as refraction, diffraction or hologram). Prism array). This will be a specialized component for the product. Another option is the lateral mechanical movement of the prism array, although this is less recommended because moving the mechanical part can make the device more complicated. Another key issue is the fixed virtual observer window separation determined by the prism angle. This can be confusing for non-standard eye-separated observers or stalkers. One of the solutions is to use a combination comprising encapsulated liquid-crystal domains, as shown in Figure 1-5. Then, the electric field can be folded, and the limbs are skewed. This purchase method can be combined with a prism array to continuously provide variable skew and fixed skew continuously. In another solution, the liquid crystal layer can be used to cover the structural edges of the prism array. The electric field then controls the refractive index, as well as the skew angle. If the virtual observer window has the secret of different eyes and the width of the track, the variable skew combination is not needed. , mouth 99 200844693 The car is noisy solution is to use a controllable prism array, such as e complement (four) prism array (as shown in Figure 27) or fill the liquid crystal prism (Figure 20) . In Fig. 17, the layer having the prism element 159 includes electrodes 1517, 1518 and a cavity filled with two separation liquids 519, 1520. Each liquid fills the prismatic portion of the cavity. As an example, the liquid can be oil or water. The slope of the surface between the liquids 1519 and mo is determined by the voltage applied to the electrodes bi?. If the liquid is drunk, the beam will be biased, and the bias is determined by the voltage applied to the electrodes 1517, 1518. For this reason, the prism element 159 acts as a controllable filament element. For the implementation of the need to track the virtual weaver window to the observer's eye month, the electronic holographic technology is provided, which is an important feature for the method of asking people. The patent application number de 102007G24mG, DE 1G2_24236.2, filed by the applicant, describes the tracking of the virtual observer window with prism elements to the observer's eyes.

Here is an embodiment for a compact handheld display. RTM Epson (RTM) Corporation of japan has published a monochrome electronic address space optical modulator, such as the D4:L3D13U 1.3 inch screen size. An illustrative example is the use of a D4:L3D13U liquid crystal display panel as a spatial light modulator. It has HDTV-resolution (1920 x 1080 pixels), 15 μm pixel pitch and 28.8 mm X 16-2 mm panel area. This panel is typically used in 2D image projection displays. 100 200844693 k 赃 is the observer distance calculated for the wavelength of the applied s(). For this escaping _ _ face is to make the thief phase handle (Bukhart code). It takes two pixels to encode a complex number. The three associated pixels are vertically aligned. If the prism array beam splitter is integrated into the spatial light modulator, the prism array spacing will be 30 μΓη. If the astigmatism, the spacing between the prism arrays and the edge array is slightly different, the perspective shortening is handled. 71 The height of the virtual weaver window is determined by the spacing of 3 * 15 μηι = 45 μηη - determined by a complex number and is 7.Gnim. The width of the virtual observer window is determined by the spacing of the prism array 30, and is 1〇.6. Both values are greater than the pupil of the eye. Therefore, if the virtual observer window is in the position of the eye, the hologram reconstruction can be seen in each eye. The holographic reconstruction is from the holographic image of the two-dimensional code, so there is no flash problem in the one-dimensional coding described above. This ensures high spatial visual quality and high depth impressi〇n quality. When the separation of the eyes is 65mm, the prism must be deflected by 32 5mm. More precisely, the maximum intensity of the Sin〇Squared intensity function of the package requires a skew of 32.5 mm. For an observer distance of 0.5 m, this corresponds to ± 3 72. Angle. For the refractive index n = L5, the appropriate prism angle is soil 744. . The prism angle is defined as the angle between the base and the bevel of the prism. 101 200844693 For the level in the observer plane of the 1〇.6 face, the position of the other eye is the distance of about 6 diffraction classes (meaning 65 ugly i〇 6mm). The crosstalk caused by the higher diffraction order is therefore negligible because the prism array has a high fill factor, meaning close to 100%. This is an embodiment used in large awards. The holographic display can be designed to use the phase adjustment _ _ _ Wei, and shoot 5 () μ η like the shed distance and 2G English pair of screen size. For a TV like a lang, the screen can be close to 4G. The observer distance for this design is 2m and the wavelength is 633 legs. Two spatially modulated pixels of the spatial light modulation n are used to encode a complex number. The two associated pixels are vertical touches and correspond to a difficult vertical spacing of 2 *5〇卿 - 100 μιη. By integrating the prism array into the spatial light modulator, the horizontal spacing of the prism array is also 2*50 μπι: 1〇〇_, because each prism contains two slopes, and each slope is used for spatial light modulation. A field of the device. The virtual observer that produces 12 7 faces is considered to have a larger width and height than the pupil of the eye. Therefore, if the virtual observation scorns S at the position of the eye, each eye _ can see the hologram reconstruction. The hologram reconstruction is a holographic image from a two-dimensional code, and there is no flash problem in the one-dimensional code itself. This high-level air quality and high depth impression quality. 102 200844693 When the separation of the eyes is 65mm, the prism must deflect light ± 32 5 bribes. More sophisticated, the maximum value of the sinc-sqwed function of the intensity package needs to be skewed by ±^cut. For an observer distance of 2 m, this corresponds to an increase of 3. Angle. For refractive index n = U, the appropriate prism limb is ± 谨. . Wei New is the angle between the base and the bevel of the prism. The above example is for the observer to distance the space modulator from 5 〇 and 2 m. In summary, this embodiment can be applied to an observer distance of 5 〇 cm to 2 m from the spatial light modulator. The screen size can range from 1cm (such as a mobile phone secondary screen) to 50 inches (such as a large TV). Laser source RGB solid-state laser sources, based on, for example, GaInAs or GalnAsN materials, are suitable light sources for compact holographic displays because they are compact 'And has a high degree of light directivity. Such light sources include RGB Vertical Cavity Surface Emitting Lasers (VCSELs) manufactured by Novalux (RTM) Inc., CA, USA. Such a source can be provided as a single laser or laser array, although each source can utilize a diffractive optical element to produce multiple beams. The beam can be transmitted in a multimode fiber because if the coherence is too high for use in a compact hologram display, this may reduce the homology step 103 200844693 and will not cause unwanted processing, such as Laser class pattern. The array of laser sources can be one or two dimensional. - Organic Light Emitting Diode Materials Infrared organic light emitting diode materials have been proposed. For example, Del Cafto et al. published electroluminescence in organic light-emitting polar materials based on perylenediimide_doped tris (8-quinolinolato) aluminium, as in Applied Physics Letters vol. 88, 071117 (2006). What is described in . The children showed the electroluminescence at a wavelength of 805 nm. Domercq et al. published a material for an approximately infrared organic light emitting diode in J Phys Chem B vol 108, 8647-8651 (2004). The preparation of an organic light-emitting diode material on a transparent substrate has been described. For example, in US 7,098,591, organic light-emitting diode materials are prepared on transparent indium tin oxide electrodes. The electrode is prepared on a transparent substrate, and the transparent substrate can be a stone-cut glass (|) Pazhou (: 拙§1). These components may be included in a money-emitting diode device towel having a squeaking plate. The indium tin oxide layer can be applied to the substrate by a radio frequency magnetron sputtering tool. Indium tin oxide can be sputtered using a target containing indium oxide and tin oxide. The indium tin oxide layer can have an optical pass of about 85% in the visible range. Tin oxide steel can be smoothed to avoid localized electric field generation, which may reduce the effectiveness of the organic light-emitting diode material. A root mean square roughness of less than about 2 nm ^ 104 200844693 is preferred. One or several practical organic layers may be disposed on the patterned electrode surface. The thickness of the organic layer is typically between 2 nm and 200 nm. The conductive layer can be constructed on the organic layer in accordance with the pattern to form an anode and a cathode on both sides of the organic layer. The device can be sealed by a layer of glass to protect the active layer from damage. Summary Manufacturing Procedures The following outlines the procedures for making the Figure 2 device, but many variations of this program will be found in the prior art. In the process of manufacturing the device of Fig. 2, a transparent substrate is selected for use. Such a substrate may be a rigid substrate, such as a boron bismuth glass sheet of about 200 μm thick, or it may be a weight substrate [e.g., a polymer substrate (4) 黯 (6), such as polycarbonate.

As described in the previous section, the flip electrode is the content described in the previous section. The infrared organic light emitting diode allows the pixel substrate of the pixelated organic light emitting diode to have an organic light emitting diode. The body image is 疋^. The glass-emitting diode material can be (4), spray /, ., ^ ° infrared organic 'clothes (soIuii0ni3rocessed) on the transparent base 105 200844693 board. The sub-sealing layer, which is also an electrically insulating layer, is then disposed on the organic light-emitting diode pixel layer. Such a sealing layer may be an inorganic insulating layer 〇nOTganie insulatOT layer), i^^^(silie〇n dioxide). |, ^(silic〇nnitride) 矽 (4) iconcarbide) or it may be a polymeric layer (4) _ such as epoxy _Xy). The configuration can be performed either for the inorganic insulating layer or chemical vapor deposition or for the polymeric layer by printing or coating. The encapsulation layer' is also an electrically insulating layer and may have a neon or a thickness of less than 1 micron. Next, the optically addressed space _ rides the photosensitive layer to cover the encapsulation layer. The photosensitive layer is transparent to visible light and has a thickness of several micrometers. Such optical properties can be provided by dyes that absorb infrared light. The optically addressed spatial light tone is then completed by a configuration covering the crystal layer between the two conductive layers. The liquid crystal layer can be made into a few micrometers for amplitude modulation or phase modulation. Next, an infrared line filter and a layer are placed on the device. This can be in the form of an infrared absorbing pigment ridge, or it can be an inorganic layer, for example, with an infrared absorbing element (4). The layer between the two optically-addressed (four) light-splitting devices must be sufficiently thick to ensure that the electric field of the Weibo in the optically-addressed empty county does not affect another optical address. Performance. The infrared base layer can be sufficiently thick to target a & However, if the infrared filter layer is not thick enough, 106 200844693, for example, a glass sheet with sufficient thickness by optical adhesive can be used: two! The light modulator device and the optical transparent layer as described above, It: The layer of matter to add thickness to the layer. In any case, two; 疋1 touch can not be too far apart, so that the optical junction t-tone. For example, if the pixel width is 1 mm, the optical formula is set; the empty address (10) tree is gradually grading; in another optical layer, the liquid crystal layer is slave to perform phase modulation. The other parts of the device can be used to make 70 pieces of each of the clothes, and then combined with the first part, _ for example, a fine in the optically-addressed space, such as the glass layer, so that each optical Between the layers of the j-buttons, there is a fully separated glass-optic address space. The light is adjusted by X: light: the other parts of the device are arranged; the other parts of the device are prepared by the pixels of the light-emitting diode layer. In the first part, this has the advantage of promoting the second organic hair. For the precise alignment of the pixels of the organic W diode layer, it is also possible to use a thin transparent electrode (conducting transparent layer) coated with conductive dectrode (for example, indium tin oxide) instead of using a sufficient thickness of 107 200844693 / knife 1 layer tight Optically-spaced spatial light modulator. This electrode acts as the same hair electrode of the two liquid crystal layers. Furthermore, as a conductive electrode it is an equipotential surface t potemiai) °11 which protects the electric field' and prevents from Optically addressing 1 light cycle ^ to another optically addressed space fine-change H electric field leakage. Θ ', an example of a device structure is shown, which can be manufactured by the above program or a similar program. During use, the table φ 909 illuminates the garment structure _ in Figure 2, which is sufficiently coherent to be visible, such that the distance from the device-segment distance (closed to the scale of the device) 3 at the point 911 allows the viewer to see the three-dimensional image. . The layers in the device, from 90 up to 3, do not need to be related to each other's dimensions. Layer 90 is a base layer, such as a glass layer. : Organic light-emitting diode bottom layer, providing organic light-emitting diode power supply, and 1 is king or #刀 transparent. Layer 92 is an array of infrared organic light emitting diodes. Layer %: Bragged hologram element for at least part of the infrared fineness. In some • with the middle layer %疋 can be omitted. Layer 94 is an electrically insulating layer. Layer 95 is a light, a site, and a photosensitive layer. Layer 96 is aligned with the visible beam amplitude, 2 of the liquid crystal layer. Layer 97 is a separator layer, particularly a thin separator layer. Layer 98 is a transmissive/polar layer. Layer 99 is a linear polarizing layer. Layer _ is an infrared transition layer that transmits visible light but blocks the liquid crystal layer from the organic light-emitting diode array % and _ infrared = layer 901 疋 for visible beam phase modulation. The layer is difficult to separate layers, = is a thin separation layer. Layer 9G3 is optically addressed (4). Layer 904 is an electrically insulating layer. Layer 9〇5 is a Bragg filter hologram element for at least part of the infrared light sighting 108 200844693. In some embodiments, layer _ is w, omitted. Layer 906 is an array of infrared organic light emitting diodes. Layer 9〇7 is an organic hair 2 diode backplane layer that provides an organic light emitting diode power supply and can be all eight transparent. Layer 908 is a plane that covers the material, such as glass. During the manufacturing process: the fabrication of the device 910 can be initiated by the base layer 9', in which each layer is placed in sequence until the final layer is added. The above described procedure has the advantage of facilitating a highly accurate structure of the layer arrangement. Alternatively, the fabrication of the layer can be divided into two or more sections and bonded together with a sufficient degree of adjustment. ^ For the manufacture of the device, it is important to turn the unwanted doubles to a minimum, such as unwanted stress causing birefringence (_s_induced bireMng·). The miscellaneous or objective state of the stress-shaped double-folded guide wire changes to the elliptical polarization state of the light. The presence of the 'elliptic polarization of the light' in the device with ideal linear or _-biased state of light reduces the contrast and color-to-noise, and therefore reduces the performance of the device. The implementation is based on the Xi (4) technique, for the above-mentioned implementation of the optically-addressed spatial light-tuning double-family--a photosensitive layer that is transparent in visible silk J5, but absorbs infrared light is required in another implementation, the photosensitive layer It can be patterned to have a transparent spacing that transmits visible light, such as red, green, and blue filaments, as well as a non-transparent area that would be 109 200844693 仗 organic luminescence-aged. In this case, the salty material does not need to be transparent. In addition, it is not necessary to use infrared light for green. In the - (4) towel, the writing beam can be generated by the age to display color, for example, by a yellow light organic light emitting diode. In the filtration between the two optical New Zealand light modulators, H will need to be in a yellow towel, which has a large optical absorption, so that it can resist yellow light, but in order to reach the turtle, there is a side optical display. The purpose, 'he needs to have sufficient transmission at other optical wavelengths. In another implementation, the write beam can be subtracted from the feed line. In two optically-addressed spatial light modulators, the filter will therefore need to be optically absorbing 'in the ultraviolet light' to enable Wt ultraviolet light, but for the purpose of achieving a useful optical display' in other optics There is still a need for a sinusoidal transmission at the wavelength. Ultraviolet organic light-emitting diode materials have been published by Qiu et al Applied physies Letters 79, 2276 (2001) and Wong et al Lrg. Lett. 7 (23), 5131 (2〇〇5).
