Description

2D/3D image switching display device

technical field

An "image switching display device" particularly refers to a 2D/3D image switching display device capable of switching between 2D image and 3D image display states.

Background technique

The current well-known stereoscopic image display technology is based on the principle of using binocular disparity to receive different images through the left and right eyes, and finally fuse them into a stereoscopic image in the brain. In naked-eye stereoscopic display technology, according to its structure, it can be roughly divided into two types: lenticular lens and barrier type. The above two structures have their own advantages and disadvantages. Convex lenses are arranged continuously along one axis, and use the principle of optical refraction to produce different views of the left and right eyes. Compared with the light barrier type, because it uses the refraction of light to achieve the purpose of splitting light, there is no loss of light and good brightness. However, there are refraction restrictions at the edge of the lens structure, so that the refraction effect is not good, or due to factors such as errors in the production of lenticular lenses, and the lens surface is not easy to be flat, there will be stray light, resulting in partially blurred three-dimensional images, and It affects the display effect of the overall 3D image; in addition, the light barrier type uses a whole row of barriers to limit the light emission at certain angles, and only allows the view images at certain angles to be transmitted to the left and right eyes respectively to generate a stereoscopic image. The monocular image of the lens is relatively clear, but its inherent structural characteristics will lead to defects such as reduced brightness of the overall image and reduced image resolution.

In addition, general stereoscopic display devices can only display stereoscopic images, and cannot switch between planar and stereoscopic images. After passing through a lenticular lens (Lenticular) or a light barrier (Barrier), it will be divided into a left-eye image and a right-eye image, unless it is a plug-in stereoscopic image display module, when it is not necessary to display a stereoscopic image, the plug-in The stereoscopic image display module is disassembled from the display, but when this method is used in practice, it must be precisely aligned to avoid problems such as image resolution degradation or skew. Therefore, some operators have developed a switchable A stereoscopic image display device for displaying stereoscopic images or planar images.

For example, China Taiwan Patent Gazette, No. M371902 "display device for switching 2D plane image/3D stereoscopic image display screen", which includes a flat display and a parallax barrier panel arranged on a display surface of the flat display, wherein the The parallax barrier panel includes a barrier pattern, which includes a first electrochromic material layer and a second electrochromic material layer, and in a 2D plane image display state, the barrier pattern, the first electrochromic material layer and the second electrochromic material layer The two electrochromic material layers are both transparent, and in a 3D three-dimensional image display state, the fence pattern is an opaque pattern, and the first electrochromic material layer has a first color, and the second electrochromic material layer has a first color. The material layer has a second color.

For example, China Taiwan Patent Gazette, No. M368088 "display device for switching 2D plane image/3D stereoscopic image display screen", which includes: a first substrate; a parallax barrier unit arranged below the first substrate; a color The filter unit is arranged under the parallax barrier unit; a common electrode is arranged under the color filter unit; a liquid crystal unit is arranged under the common electrode; a plurality of thin film transistors are arranged under the liquid crystal unit; a second substrate is arranged under the liquid crystal unit A plurality of thin film transistors are under the bottom; and a light source is arranged under the second substrate; through the parallax barrier unit, the plane image and the three-dimensional image are modulated and the thickness and assembly cost of the conventional display device are reduced.

Both of the above two patents use electrochromic materials as parallax barrier devices for displaying stereoscopic images, but the common defect in their structures is that they lack the necessary electrolyte layer for electrochromic devices, because they lack the ability to provide ions to the electrochromic layer. electrolyte layer, the electrochromic device will not be able to produce a reversible reaction of oxidation or reduction to complete the coloring or decolorization change, so the two patents should not be implemented in practice; in addition, the transparent electrode layer of the parallax barrier device and the electrochromic material Layers are all set as a fence pattern, layered coating, sputtering or etching in the manufacturing process, so that each stack must be accurately aligned, the manufacturing process is quite complicated, and all stacks are set as a fence pattern, resulting in each A hollow area formed between a fence and the fence will affect the overall light penetration, refraction or reflection. Even for general 2D display, it may affect the image quality of the display, causing problems such as color difference or uneven brightness, and the hollow area between the fences will also be affected. Reduce the strength and service life of the fence; and another structure embedded in the liquid crystal display substrate in the M368088 patent is to embed a fence pattern into an insulating transparent material. Although the thickness of the liquid crystal display with three-dimensional images can be reduced, the actual manufacturing process is also is quite complex.

In addition, although the above-mentioned conventional technology can switch between two-dimensional and three-dimensional display, for handheld devices that can freely change viewing angles, the angle of three-dimensional display cannot be changed accordingly, and 3D images must be viewed in a fixed direction.

Please refer to Figures 1, 2, 3, and 4, which are three-dimensional exploded schematic diagrams and action schematic diagrams 1-3 of the first preferred embodiment of the present invention, respectively. As shown in the figure, the 2D/3D image switching display device of the present invention includes There is an image display unit 1 and an image switching unit 2, wherein:

The image display unit 1 is used to display a planar image and a stereoscopic image. The displayed stereoscopic image can be generated by software, firmware or hardware technology, for example, the planar image is converted into a left-eye image and a right-eye image by software or firmware. The double image of the image, or the two hardware devices of the lenticular lens (Lenticular) or the light barrier (Barrier) to distinguish the image into the left eye image and the right eye image, but this kind of stereoscopic image display technology is not the technical feature of this case, and has long been Disclosed technology, so no longer describe it here; Moreover, the display unit 1 can be a liquid crystal display (Liquid Crystal Display, LCD), a plasma display (Plasma Display Panel, PDP), a surface conduction electron emission display (Surface conductionElectron- emitter Display, SED), field emission display (Field Emission Display, FED), vacuum fluorescent display (Vacuum Fluorescent Display, VFD), organic light-emitting diode display (Organic Light-Emitting Diode, OLED) or electronic paper (E-Paper) among them one.

The image switching unit 2 is combined on the surface of the image display unit 1, and includes a first transparent substrate 21, a second transparent substrate 22, an electrochromic layer 23 and an electrolyte layer 24, wherein:

The lower surface of the first transparent substrate 21 is provided with a first transparent conductive element 211, which can be in the shape of a plate, sheet or film, and the materials of the first transparent substrate 21 and the second transparent substrate 22 are plastic, polymer Plastic, glass or selected from resin, polyethylene terephthalate (PolyethyleneTerephthalate, PET), polycarbonate (Poly Carbonate, PC), polyethylene (polyethylene, PE), polyvinyl chloride (Polyvinyl Chloride, PVC ), polypropylene (Poly Propylene, PP), polystyrene (Poly Styrene, PS), polymethylmethacrylate (Polymethylmethacrylate, PMMA) or one of the plastic polymers blended therewith; and the first transparent conductive element 211 and the second transparent conductive elements 221 are made of indium tin oxide (Indium Tin Oxide, ITO), indium zinc oxide (Indium Zinc Oxide, IZO), zinc aluminum oxide (Al-doped ZnO, AZO) or oxide One of the group of Impurity-DopedOxides composed of Antimony Tin Oxide (ATO).

The electrochromic layer 23 is arranged at intervals above the second transparent substrate 22, and covers the surface of the second transparent conductive elements 221, and its setting method can be prepared in the following manner: such as sol-gel method (sol-gel method). gel), vacuum sputtering (sputtering) method, electroplating (plating) method, screen printing, spray coating, anodizing method (Anodizing), photopolymerization method (photopolymerization), laser etching method, etc.; and the material of the electrochromic layer 23 It is mainly one of the transition metal element oxides or other organic compounds selected from the group consisting of anodic coloration, cathodic coloration or cathodic/anodic coloration. Generally speaking, the anode The anodic coloration material is mainly selected from chromium oxide (Cr ₂ O ₃ ), nickel oxide (NiO _x ), iridium oxide (IrO ₂ ), manganese oxide (MnO ₂ ), ferrocyanide Fe ₄ [Fe( CN) ₆ ] ₃ or nickel hydroxide Ni(OH) ₂ composed of anodic coloration (anodic coloration) transition metal element oxides or other organic compounds; cathodic coloration (cathodic coloration) materials are mainly selected from tungsten oxide (WO ₃ ) , molybdenum oxide (MoO ₃ ), niobium oxide (Nb ₂ O ₃ ), titanium oxide (TiO ₂ ), strontium titanate (SrTiO ₃ ), cathodiccoloration transition metal element oxides or other organic compounds; The cathodic/anodic coloration material is mainly composed of vanadium pentoxide (V ₂ O ₅ ), rhodium oxide (Rh ₂ O ₃ ) or cobalt oxide (CoO _x ) cathodic/anodic coloration) oxides of transition metal elements or other organic compounds, and oxides of transition metal elements such as tantalum pentoxide (Ta ₂ O ₅ ) that can also be used as solid electrolytes and ion-conducting layers.

As for the classification of different transition metal oxides as electrochromic materials, some common ones are listed in the following table:

The electrolyte layer 24 is located between the electrochromic layer 23 and the first transparent substrate 21, and its main purpose is to provide and conduct ions to the electrochromic layer 23. It can be a liquid or solid electrolyte, but the liquid electrolyte There is a problem of leakage in the component package, so generally solid electrolytes are used. One embodiment of the electrolyte layer 24 of the present invention is a solid electrolyte, preferably a proton exchange membrane (ProtonExchange Membrane), which can be ionic One of polymer membrane (Ionomer membrane), organic/inorganic hybrid membrane (Organic-Inorganic hybrid membrane) or acid/alkali polymer membrane (Membrane based on polymer and oxo-acids), wherein the ionic polymer membrane can be a Polymerized perfluorosulfonic acid (PFSA) membrane; if it is a liquid electrolyte, lithium perchlorate (LiClO ₄ ), potassium hydroxide (KOH), sodium hydroxide (NaOH) or sodium silicate can be used.

This type of electrochromic material refers to a material that undergoes a reversible reaction of oxidation or reduction after an electric potential is applied, resulting in a color change. The working principle of the electrochromic layer 23 is that the valence state of transition metal element ions in the electrochromic material changes, resulting in dyeing and fading reactions. When a bias voltage is applied to the electrochromic layer 23, the ions originally stored in the electrolyte layer 24 will diffuse and move to the electrochromic layer 23, and electrons will also be injected into the electrochromic layer 23 through the first transparent conductive element 221. The color-changing layer 23 is to maintain the electrical neutrality of the color-changing layer. After electrons and ions are injected into the electrochromic layer 23 at the same time, the redox state of the material of the electrochromic layer 23 is gradually changed, and then the refractive index of the electrochromic layer 23 is increased. And the transmittance changes thereupon, this is a dyeing process, and this process can be completed within a few seconds to one minute, therefore, in " Fig. 3 ", it can be clearly seen that the electrochromic layer 23 changes from transparent to a dyed state, An opaque light-shielding region 231 is formed, and when the bias voltage applied to the electrochromic layer 23 disappears, the electrochromic layer 23 changes from a dyed state to a transparent state, which is an anodic color change method.

Conversely, when a reverse voltage or zero bias is applied to the electrochromic layer 23, ions will return to the electrolyte layer 24 from the electrochromic layer 23 along the opposite path, and the electrochromic layer 23 returns to its original state. Therefore, it can be clearly seen in "Fig. 4" that the electrochromic layer 23 turns from the opaque light-shielding region 231 in the dyed state to a transparent state, and when applied to the electrochromic layer 23 After the bias voltage of the electrochromic layer 23 disappears, the electrochromic layer 23 changes from a transparent state to a dyed state, and restores the opaque light-shielding region 231 , which is a way of cathodic discoloration.

Since the electrochromic layers 23 are arranged on the upper surface of the second transparent substrate 22 in a plurality of intervals, and the electrochromic layers 23 are arranged on the second transparent conductive elements 221, therefore, the first After the transparent conductive element 211 is electrically connected to the second transparent conductive elements 221, the electrochromic layers 23 produce color changes, thus producing a plurality of opaque light-shielding regions 231 arranged at intervals, and the image display unit 1 When displaying the processed multiple images (divided into left-eye image L and right-eye image R), through the shading areas 231 to remove some overlapping image areas, no moire will be generated after being received by the naked eye; moreover Generally, when displaying a stereoscopic image, two additional devices, a lenticular lens (Lenticular) or a light barrier (Barrier), are added to the display unit, but through the 2D/3D image switching display device of the present invention, when displaying a stereoscopic image, it is convenient The stereoscopic image which has been divided into left-eye image and right-eye image can be directly displayed by the display unit.

Please refer to "Figures 5, 6, 7", which are diagrams of different stacked combinations of the first preferred embodiment of the present invention. The lower surface of the transparent substrate 21, or the second transparent conductive elements 221 are arranged at multiple intervals on the upper surface of the second transparent substrate 22, or the first and second transparent conductive elements 211, 221 are arranged at plural intervals. On the surfaces of the first and second transparent substrates 21, 22, the arrangement direction is the same as the arrangement direction of the electrochromic layer 23. These structures are only other combinations of the first embodiment, but in order to simplify the manufacturing process, the best In a good practice, only a plurality of electrochromic layers 23 arranged at intervals in a layered structure can achieve a good color-changing mechanism and masking effect.

In addition, in order to prevent the first transparent conductive element 211 from being corroded by the electrolyte, a protective layer (not shown) can be further provided on its surface, or to prevent the electrochromic layer 23 from being hydrolyzed by the electrolyte and increase the service life, A protective layer (not shown) is further provided between the electrochromic layer 23 and the electrolyte layer 24, wherein the material of the protective layer is selected from silicon dioxide (SiO ₂ ), aluminum oxide (Al ₂ O ₃ ), tetramethyldisiloxane (tetramethyldisiloxane, TMDSO, C ₄ H ₁₄ OSi ₂ ) or other carbon-silicon-oxide film (carbon-silicon-oxide layer), etc., and electroplating or sputtering, etc. The method is set in the above stack.

That is, the electrolyte layer 24 is arranged at intervals between the first transparent substrate 21 and the electrochromic layer 23, but the electrolyte layer 24 is arranged in such a way that the preferred application is to use the electrolyte layer 24 as an electrochromic layer. The auxiliary discoloration function of the chromogenic layer 23 is to effectively deepen the contrast of the transmittance, which means that the electrolyte layer can be selected from electrochromic materials, and its material can be selected from anode coloration (anodic coloration), cathode coloration (cathodic coloration) or cathode color change. One of the transition metal element oxides or other organic compounds composed of cathodic/anodic coloration. Generally speaking, the anodic coloration (anodic coloration) material is mainly selected from chromium oxide (Cr ₂ O ₃ ) , nickel oxide (NiO _x ), iridium oxide (IrO ₂ ), manganese oxide (MnO ₂ ), ferric ferrocyanide Fe ₄ [Fe(CN) ₆ ] ₃ or nickel hydroxide Ni(OH) ₂ Anodic coloration transition metal oxides; cathodic coloration materials are mainly selected from tungsten oxide (WO ₃ ), molybdenum oxide (MoO ₃ ), niobium oxide (Nb ₂ O ₃ ), titanium oxide (TiO ₂ ), strontium titanate (SrTiO ₃ ) composed of cathodic coloration (cathodic coloration) transition metal element oxides; and cathodic/anodic coloration (cathodic/anodic coloration) materials are mainly selected from vanadium pentoxide (V ₂ O ₅ ) , rhodium oxide (Rh ₂ O ₃ ) or cobalt oxide (CoO _x ) is composed of cathodic/anodic coloration transition metal element oxides, and there are also pentoxides that can also be used as solid electrolytes and ion-conducting layers. Ditantalum (Ta ₂ O ₅ ) and other transition metal element oxides; in addition, if the electrolyte layer 24 is used as an auxiliary color-changing layer, when the electrochromic layer 23 is selected from cathodic color-changing materials, the auxiliary color-changing layer needs to use anodic color-changing materials. Vice versa, therefore, when the electrochromic layer 23 is dyed, the auxiliary color-changing layer is also dyed, and when the electrochromic layer 23 fades, the auxiliary color-changing layer also undergoes a fading reaction.

The above-mentioned first and second electrochromic layers 232, 233 are set up in the same way as in the previous embodiment, and are selected from the sol-gel method (sol-gel), vacuum sputtering (sputtering) method, electroplating (plating) method, screen printing, spray coating, anodic oxidation method, photopolymerization method, laser etching method, etc., are arranged on each substrate, and the materials of the first and second electrochromic layers 232, 233 can be selected from anodic coloration (anodic coloration) ), cathodic coloration (cathodic coloration) or cathodic/anodic coloration (cathodic/anodic coloration) transition metal element oxides or other organic compound groups, in addition, the first and second electrolyte layers 241, 242 The material of the electrolyte layer can be liquid electrolyte or solid electrolyte, but if the first and second electrolyte layers 241, 242 can not only provide the function of ions, but also have the function of assisting discoloration, the material of the electrolyte layer is as the above-mentioned first As described in the second preferred embodiment, electrochromic materials can be selected. When the electrochromic layer 23 is selected from cathodic color-changing materials, the auxiliary color-changing layer needs to use anodic color-changing materials, and vice versa. Therefore, when the electrochromic layer 23 is dyed , the auxiliary color-changing layer is also dyed, and when the electrochromic layer 23 fades, the auxiliary color-changing layer also undergoes a fading reaction, and the first and second electrolyte layers 241, 242 correspond to the first and second electrochromic layers. The positions and directions of the layers 232 and 233 are arranged in multiple intervals in each stacked layer, so that the electrochromic layer of each layer can achieve a better light-shielding effect after generating a light-shielding area.

The setting method of the sixth embodiment is to combine two sets of electrochromic devices. The color-changing layer 232 is arranged in plural intervals toward the first arrangement direction, and the second electrochromic layer 233 is arranged in plural intervals in the second arrangement direction, and the first arrangement direction and the second arrangement direction are at right angles to each other. Optimum setting angle, the first electrochromic layers 232 and the second electrochromic layers 233 respectively produce a plurality of light-shielding regions arranged at intervals according to voltage control. It should be noted that the third transparent conductive layer 25 means that a third transparent conductive element is provided on the upper or lower surface of a third transparent substrate, or a third transparent conductive element is provided on the upper surface of the third transparent substrate, and a third transparent conductive element is provided on the lower surface of the third transparent substrate. The fourth transparent conductive element, so that the color of the first electrochromic layer changes according to the electrical conduction between the first transparent conductive element and the third transparent conductive element, and the second electrochromic layer changes according to the electrical conduction between the first transparent conductive element and the third transparent conductive element. The second transparent conductive element is electrically connected to the fourth transparent conductive element to produce a color change. .

Its operating principle is that the display device has a sensing element (not shown) and a control element (not shown), the sensing element and the control element are electrically connected to each other, wherein the sensing element can be a gyroscope instrument (Gyroscope), and the control element is electrically connected to the first transparent conductive element 211, the second transparent conductive element 221 and the third transparent conductive layer 25, wherein the sensing element is used to sense the display The rotation direction of the device (such as horizontal or vertical), and send the sensing signal to the control element, and then switch the voltage of the first, second transparent conductive elements 211, 221, and the third transparent conductive layer 25 through the control element, To make the first electrochromic layer 232 and the second electrochromic layer 233 change their state and change color. The first electrochromic layers 232 are colored so that the image of the image display unit 1 passes through the parallax barrier formed by the first electrochromic layers 232 to form the stereoscopic image in the first arrangement direction; But when the image display unit 1 is changed to face the viewer E in the second arrangement direction, the control element controls the voltage switching of the first and second transparent conductive elements 211, 221 and the third transparent conductive layer 25, so that the first voltage The states of the first electrochromic layer 232 and the first electrolyte layer 241 are changed to decolorize the originally colored first electrochromic layer 232 and to color the second electrochromic layer 233. Therefore, when the image passes through the first electrochromic layer 232 After the parallax barrier formed by the two electrochromic layers 233, the stereoscopic image is formed in the second arrangement direction. The voltage switching of the transparent conductive layer 25 causes the first and second electrochromic layers 232 and 233 to fade, and the image display unit 1 switches from stereoscopic image display to planar image display.

Please refer to "Fig. 16", which is a three-dimensional exploded schematic view of the seventh preferred embodiment of the present invention. As shown in the figure, this embodiment differs from the sixth preferred embodiment in that the first The positions of the electrochromic layer 232 and the first electrolyte layer 241 are exchanged, and the positions of the second electrochromic layer 233 and the second electrolyte layer 242 are exchanged. The characteristics and the operation principle of adjusting the shading angle used when the stereoscopic image is displayed according to the viewing angle are the same as the sixth preferred embodiment above, except that the two groups of electrochromic devices of the sixth and seventh preferred embodiments are the same , the stacking order does not have to be the same, because each electrochromic layer is controlled by voltage separately, as long as after the combination, the first arrangement direction of the first electrochromic layer 232 and the second electrochromic layer 233 is the same as that of the second electrochromic layer. The arrangement directions can be different. Therefore, the order of arrangement of the electrolyte layer and the electrochromic layer in the two sets of stacks can be the same or different, and all of them should belong to the scope of the present invention.
