When I want to pick on the dashboard When you take U Besun, you must not pay attention to the danger at the same time. The reading condition of the locomotive is therefore easy = when the data projection designed by the inventor is applied to the locomotive, it is set on the locomotive cap—the appropriate position, but because the locomotive driver is in —Open space, except for driving students who are "higher in shaking", if the outside light is strong, such as the sun, the driving information displayed by the projection system will easily become blurred, making it impossible for the driver to clear it. take. In addition, when the car is driving at a high speed (such as a racing vehicle), the driver often wears a hood or ㈣ to protect the driver ’s safety. At this time, data projection is also required to provide real-time driving information and protect the driver ’s safety. . However, most of the data projections currently designed for motorists or locomotives are direct projection systems, which take up a lot of space, are not easy to assemble, and require a lot of power. What's more, its projection light path has a high light scattering loss, a low calendering efficiency, and a large light amount loss. The traditional use of projected real images for eyeball imaging, if its magnification is to be increased, it is necessary to lengthen the distance between the projection lens group and the eyeball, so if you want to increase the image magnification, you need to increase the occupation of the projection system. (2) 2 :: $$ :: In addition, the operation of the simulation game that forms a projected real image in the eyes) :,% shifted image is blurry or strict; the ghosts ... Dubler effect quotes 1-:: II & quot To this point, the Buhler effect is the same as the human capital. As many video recorders or cameras used by many people at the same time: when a person holding the camera and trying to focus while moving, they will find that they can adjust their focal lengths straight forward and backward. This is because the camera must know exactly what parts are Only the subject to be captured, the distance of the subject from the camera, etc., can be properly focused to produce a clear image. People ’s eyes are as clear as the lens of a camera. You must adjust the curvature of the water tank and the length of the eye axis quickly to adapt to different distances. As shown in FIG. H, when the image of the object seen by the eyes is a still real image 6, the eyeball 5 and the crystalline lens 51 are maintained in a normal state; then referring to FIG. 1b, when the real image 61 and the eyeball 501 are in a relative movement, In order to capture the correct image, the eyeball 501 must quickly adjust the length of the eye axis and the curvature of the crystalline lens 511. As shown in Figure lc, the curvature of the crystalline lens 5 becomes smaller and becomes flatter, and the eye axis of the eyeball 502 is longer to accommodate the crystalline lens 5 The curvature of 12 becomes shorter; or as shown in Figure 1d, the curvature of the crystalline lens 5 丨 3 becomes larger and becomes thicker, and the axis length of the eyeball 5 0 3 becomes longer to accommodate the curvature of the crystalline lens 5 丨 3. As shown in Figure 1e, the crystalline lens 5 丨 4 is adjusted to a correct curvature, and the eye axis is adjusted to the state of 504. In the process of adjustment, since the speed of object movement is inferior to the speed of eyeball adjustment, there will be an afterimage 6 2 ', which is the conventional Doppler effect. In addition, the paper size of this paper that is quickly adjusted for focal length is subject to the Chinese National Standard (CNS) A4 specification (210X297 mm) # ------- V. Description of the invention (3) Force, long-term I ^ garden micro blood ^ a lot Circulating blood will cause pressure on the eyeballs to open to the eyes frequently. The high intraocular pressure caused by the whole focal length is not only equal to the feeling of discomfort for people. In severe cases, there is a fear of magnification of retinal detachment. -A new display device is still needed in Meguro city-a new display device that can effectively enlarge the image provided by _4 and press the eyeballs' can be used at close range and for a long time will not = clear discomfort. ’Thinking of a kind of" refractive image display device "that can be researched and experimented by the inventor for a long time, and based on the spirit of active invention to solve the above-mentioned problems, this invention that finally benefits the world is redundant. [III] Summary of the invention The main purpose of the present invention is to provide a refracting image display device, which can reduce the loss of light source by the focusing characteristics of the diffraction residual, and has relatively low image clarity. . Another object of the present invention is to provide a refracted image display device, which can reduce the occupied space, simplify the complexity of assembly, save the consumed power and power, and reduce the fluctuation of the image as the user moves. Another object of the present invention is to provide an image display device that can effectively enlarge the image provided by the microdisplay, occupy a small space, can maintain the image resolution, extend the use time, low the cost of materials, and adjust the magnification 4 200409951 V. Description of the invention (4) The contrast ratio of each image is high, and the Doppler and ghost effects are reduced. It is suitable as a helmet-type display device. In order to achieve the above purpose, the refracting image display device for traffic vehicles of the present invention is matched with A hood mainly includes: at least one display unit; at least one light source for providing light from the display unit; a refractive lens group for deflecting light emitted from or reflected from the display unit; a virtual image imaging Mirrors and groups, use alpha to reflect or transmit the light that has passed through the folded mirror group, and make .Hy reflected light to form a virtual image, and a diffractive mirror group, located between the refraction mirror group and the virtual image imaging mirror Between groups to increase the half-brightness angle of the light emitted from the display unit or reflected from the display unit; wherein the refractive lens group is between the display unit and the display unit; Between the virtual image imaging lens group; the refraction lens group and the display unit form an included angle γ; and the included angle Υ is greater than 0 degrees, less than 0 degrees, and the image of tf displayed by Θ showing single TG passes through the refractive lens group Deflection refraction formation-a real image inverted with the original image, and then converted into a virtual image inverted with the original image by the virtual image imaging lens group. The present invention is provided with at least one diffractive lens group in the above projection system, and the projection system starts to operate When it is controlled by the circuit board, it displays: Displaying driving image information such as speed and fuel quantity, etc. The image information is refracted by the i-deflecting mirror group and the light condensing by the above-mentioned diffractive mirror group, and then displayed on the On the hood < virtual imaging imaging lens group. Because the diffractive lens group has an increased half-glow angle, which is similar to the micro-focusing feature, it can diffuse and collimate light '. Therefore, the image information can be used to reduce the light source. The "lost" relatively improves the brightness and sharpness of the image, so that users can know the relevant image information clearly. ^ Paper standards are applicable ^ National Standards (cns) ^! ^ 0 × 2897 publicly disclosed 200409951

Detailed description of the present invention Please refer to FIG. 2 and FIGS. 3a, 3b, and 3c. These 4 figures are schematic diagrams of real image and virtual image differences of eye imaging. Figure 2 shows the real image 4 projected by the conventional projection system. In the case where the eye considers the real image, the eye must be properly focused so that the image is imaged on the retina to "see" the image 41, as described in the previous paragraph. As mentioned above, the focusing process will bring pressure to the eyes. Figures 3a to 3c show what the eye of the invention sees as a virtual image. In this case, when the imaging lens group (concave mirror) 260 is transparent, the real image 4 2 projected by the display unit (not shown) will form a virtual image 4 3 after the imaging lens group 2 60, and because When the human eye observes the virtual image of the reflective surface, the eyeball adjusts its focus on the reflective surface. When the human eye views the virtual image of the reflective surface, the eye does not need to adjust the focal length, but only needs to focus on the reflective surface. And if there is movement of the reflecting object or the image projected on the reflecting surface in the display, because the person focusing on the eye only applies the Chinese standard (CNS) A4 specification (210X297 mm) to this paper size (please read the precautions on the back first) (Fill in the columns on this page) Install i, P, \ 呑. 200409951 A7 ______B7 V. Description of the invention (6) It is a reflective surface, that is, the eyeball does not need to adjust the focus distance significantly due to the reflected object or the image motion in the display, as long as the reflected The image of an object or a moving image on the display is projected on the retina after passing through the lens in the eyeball. It can be recognized by several layers of the retina, which can make the eye clearly see the image or distinguish the movement of the image, but it does not have to follow the image. Quickly adjust the length of the eyeball to suit the movement of the image, so that the intraocular pressure will not rise. The distance between the virtual image of the non-transparent reflecting surface in the eyeball can be roughly explained in Figures 3b and 3c. Because the retina of the eyeball has a multi-layered structure, the eyeball can feel the distance of the image in a multi-layered structure. When the virtual image 44 enters the eyeball via a reflective surface 260, the eyeball will automatically adjust the relative image of the non-penetrating reflective surface through the lens to the retina, and the virtual 44 image formed by reflection on the reflective surface after passing through the eye lens. It will be imaged on the multi-layered structure of the retina with the focus adjustment of the eyeball lens fixed on the reflecting surface. The eye "feels" through the retina to the image 4 1 2 before the eyeball retina, that is, the image exists in front of the retina. , Between the crystalline lens and the retina, as shown in Figure 3b, and after it is transmitted to the brain, the virtual image is seen before the reflective surface, but the focal length of the eyeball has not changed. When the real image is located on the surface of the reflecting surface 260, the image 4? 3 refracted by the crystalline lens will also fall on the surface of the retina. In combination with Figure 3b & 3c, you can explain the relative motion of the object or image. From the above description, it can be known that when the virtual image moves, the eyeball does not need to adjust the focal length, so there is no Doppler effect of increased intraocular pressure, image overlap, or afterimage. This problem is also an advantage of virtual image projection imaging. Please refer to FIG. 4, FIG. 5, and FIG. 6. These three figures are schematic diagrams of the refractive lens group used in the present invention compared with the conventional art.

Description of the invention (7) The convex lens 170 is directly projected by the light path of the external light source 180 and the display unit 190.

Description of the invention (11) " * The focus of the above-mentioned diffraction lens group 11 is displayed on the imaging unit 21 of the locomotive cap 2. The distance between the refractive lens group 丨 3 and the imaging unit 2 丨 (virtual imaging imaging lens group) is greater than the focal length of the refractive lens group 丨 3 (a convex lens in this embodiment) (in this embodiment, it is between the focal distance and two Between focal lengths). And the refractive lens group 13 (a convex lens in this embodiment) and the hollow fluorescent display (Vfd) form an included angle of about 20 degrees. The distance between the windshield lens of the motorcycle cap and the inverted image formed by the refracted refraction of the refractive lens group is between the focal length of the refractive lens group 13 (a convex lens in this embodiment) and the focal length of the windshield lens. After the image light is refracted and enlarged by the refraction lens group 13, after the refraction lens group 3, an inverted magnified real image is formed on the windshield mirror surface of the motorcycle cap. Later, the reflection from the windshield mirror-like surface of this concave lens is magnified and converted into a magnified virtual image in the eyes of the driver. Because the focal length of the general goggles is very large, the reflected divergent light then forms an enlarged virtual image in the driver's eyes. Since the diffractive lens group 11 used in the present invention has focusing characteristics, the imaging information of the light source 12 of the projection system 1 can be focused by the diffractive lens group 11 to form nearly parallel light, and therefore can reduce The light source of the luminous source 12 is lost, the imaging clarity is relatively improved, and the imaging brightness is increased under the same power consumption power, and the eye parts 33 of the driver 31 can clearly observe and obtain relevant driving information. It can be known from the foregoing embodiments that the imaging principle of the present invention is virtual image imaging, which mainly uses a refractive lens group (convex lens) to form an enlarged real image inverted from the original image; and then uses a virtual image imaging unit (concave mirror, concave lens or plane mirror) to form A magnified virtual image inverted from the original image. This kind of glasses-type image display device using the virtual image imaging principle will not cause eye pressure, even if it is used for a long time, there will be no dizziness within a few hours.

Description of the Invention (12) One of the major breakthroughs in today's glasses or head-mounted image display technology. The invention uses the formation of a virtual image on the eyeball, so when the user's head moves, the image blur caused by the Doppler effect and the ghost effect is reduced. In addition, since the present invention uses refracted light to form a virtual image in the user's eyeball, only the distance, angle and even curvature of the virtual image imaging lens group or the refractive lens group (such as a convex lens) need to be adjusted when magnifying the image. Simple 'takes up little space. Compared to the traditional projection display device that forms a real image in the user's eyeball and requires a large space, it has the relative advantages of simplified operation and large space flexibility. Furthermore, since the present invention forms a virtual image in the user's eyes by refraction, which is different from a general projection system that uses projection to form a real image in the user's eyes, there is no need to occupy a large amount of volume as the traditional projection system that forms a real image. The projection of the present invention Compared with the system, the volume occupied by the system is greatly reduced, and the weight is also greatly reduced, which meets the requirements of light, thin and short. In addition, the present invention uses refracted light to form a virtual image in the user's eyeball, so the contrast of the imaging is relatively high, the darkroom effect is large, and it is less affected by the ambient light. Compared with the traditional projection display device that forms a real image in the user's eyeball, The image quality is better. And when the user uses it, for the surrounding non-users, because the image is refraction imaging, the light refraction angle of the transmitted virtual image imaging environment group is large, and it will not affect other people around the same height as the user's line of sight, and the interference is relatively low. . More specifically, the refracted image display device of the present invention has the advantages of small size, low material cost, low power consumption, easy portability, high flexibility in use, and can reduce production costs, which is quite in line with market demand. 192 paper sizes, Lai Xie Jia Xian (CNS) A4 specifications (please read the precautions on the back before filling in the columns on this page) ----- Order --------- MW! 1-^ 200409951 A7--B7 V.
