Description of the invention (~ " "I. Technical Field to which the Invention belongs" The present invention relates to a refractive image display device, especially a device suitable for making information display clearer. Refraction image display device. [II. Prior technology] The driving safety of motor vehicles is the first priority. However, whether it is a car or a locomotive (the car information is often set on an instrument panel, when the driver wants to capture the above cargo information, It is impossible to pay attention to the driving conditions at the same time, so it is easy to cause danger. At present, there is a data projection system designed for car drivers. If it is applied to a locomotive, it is appropriate to set one on the locomotive cap. Location, but because the locomotive driver is in an open space, in addition to the sloshing caused by the driving room, if the external light is strong, such as the sun, the driving information displayed by the projection system is easy. Blurred to make the driver ’s broadcast clear. In addition, when the car is driving at high speed (such as racing vehicles), the driver often wears a hood or helmet to protect the driver. Safety, at this time, a data projection system is also required to provide real-time driving information and protect the safety of the driver. However, most data projection systems designed for car or locomotive drivers are mostly direct projection projection systems: they occupy a large space It is inconvenient to assemble and consumes a lot of electric power. What's more, the light scattering loss is high in its projection light path, so the light use efficiency is low and the amount of light phase loss is large. Traditionally, the projection real image is used for eyeball imaging, which enlarges If you want to increase the magnification, you need 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 space occupied by the projection system. ^ The paper size applies the Chinese National Standard (CNS) A4 specification (210X297).

In addition, the simulated tour that forms a real image in the eyes: Γ The user's head moves (such as driving a motor vehicle or a motor vehicle for transportation) Top :: Sang Zuo), it will cause serious shaking due to ghosts and Doppler effect, so the display quality is not good. See figure iule. This is the capital of the common practice. As many video cameras or cameras used by many people at the same time, when the user holds the camera in motion while trying to focus, they will find that the camera lens-adjust its focus straight forward and backward, because the camera must be faint Try to clarify which parts are the subject you want to shoot, the distance from the subject to the camera, etc., so that you can focus correctly and take a clear image. Human eyes are just like the lens of a camera. 4. The length of the eye axis is adapted to different scenes. As shown by _, when the image of the object seen by Yan Qing is a static real image 6, the eyeball 5 and the crystalline lens 51 are maintained in a normal state; then see Figure ib. When the real image is in a relative movement with the eyeball 501, the eyeball 50 1 needs to quickly adjust the length of the eye axis and the curvature of the crystalline lens 5 丨 丨 in order to grasp the correct image, as shown in Figure 1c. The curvature of 5 丨 2 becomes smaller and flattened, and the eye axis length of eyeball 5 02 becomes shorter to accommodate the curvature of crystalline lens 5 丨 2, or as shown in Figure 1d, the curvature of crystalline lens 5 1 3 becomes larger and becomes It is thicker, and the axial length of the eyeball 503 becomes longer to accommodate the curvature of the crystalline lens 51 3. Finally, as shown in Figure 1e, the crystalline lens 5 1 4 is adjusted to a correct curvature, and the eye axis is adjusted to 5 04 status. During the adjustment process, since the speed of object movement is higher than the speed of eyeball adjustment, there will be an afterimage 62, which is the conventional Doppler effect. In addition, the paper size of this paper that can be adjusted quickly is subject to the Chinese National Standard (CNS) A4 specification (210X297). A7 __Β7 V. Description of the invention (3) — ~ & Zhongmugenqiu Zhouyuan's micro blood vessels circulate a large amount of blood Causes pressure on the eyeballs for a long time and frequent adjustment of the focal pressure caused by frequent adjustment of the focal length. Not only does it cause discomfort to the human eye, but in serious cases, there is a fear of retinal detachment! Therefore, a new display device is still needed on the market, which can effectively enlarge the image provided by the micro display and maintain high resolution. Its imaging method does not press the eyeball, and it can be used at short distances and for a long time without causing eye damage. Sunny symptoms. Because of this, Mao Yueren, in the spirit of active invention, was thinking about a "refractive image display device" that could solve the above problems. After several research experiments, he finally completed this invention that benefits the world. [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 using the focusing characteristics of the diffractive lens group, and relatively improve the image clarity. . Another object of the present invention is to provide a refracted image display device, which reduces the occupied space, simplifies the complexity of assembly, and saves the consumed power. The power reduces the fluctuation of the image as the user moves. Yet another object of the present invention is to provide an image display device that can effectively enlarge the image provided by the microdisplay with a small footprint, can maintain the image resolution, extend the use time, reduce the cost of materials, and adjust the paper size by magnification.

Description of the invention (4 ) Easy, high image brightness contrast, reducing Doppler and ghost effects, suitable as a helmet-type display device. In order to achieve the above purpose, the refractive image display device for traffic vehicles of the present invention is equipped with a hood, mainly including: at least A display unit; at least a light source 'for providing the display light; a refraction mirror group for deflection of light emitted from or reflected from the display unit; a virtual image imaging mirror group for reflection or transmission The light that penetrates the refractive lens group and makes the light reflected by the child form a virtual image; and a diffractive mirror group is located between the refractive lens group and the virtual imaging lens group for improving the display unit. The half-brightness angle of the light emitted or reflected from the display unit; wherein the refractive lens group is between the display unit and the virtual image imaging lens group; the refractive lens group and the display unit form an included angle Y; and the cool angle Ya is greater than 0 degrees and less than 90 degrees; and the image displayed by the display unit is formed by deflection and refraction of the refractive lens group-a real image inverted with the original image, and then converted into an inverted image with the original image through the virtual image imaging lens group Virtual image. The present invention is provided with at least one diffractive lens group in the above-mentioned projection system. When the projection system starts to operate and is controlled by a circuit board, the light source can display driving image information such as speed and fuel quantity. This development information is refracted by the above-mentioned refraction lens group and condensed by the above-mentioned diffractive lens group, and then displayed on the hood (virtual image imaging lens group. Because the diffractive lens group has an increased angle, which is similar to micro-focusing characteristics The imaging information of the “scattered parallel light” projection can be used to: Integrate: Therefore, the loss of light source is reduced, and the brightness and clarity of the image are relatively improved, so that the user can clearly understand Relevant image information.

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 that the eye regards the real image, the eye must be properly focused so that the image is imaged on the retina in order to see the image 41, as described in the previous paragraph. The focusing process will bring pressure to the eyes. Figures 3 & 30 are the cases where the eye of the present invention considers 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 6 0. 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 motion on the reflective object or the image projected on the reflective surface in the display, the eye will focus on the only person (please read the precautions on the back before filling in the columns on this page) ----- Order ---- ----- 9 580588 A7 ____B7___ 5. Description of the invention (6) It is a reflecting surface, that is, the eyeball does not need to adjust the focal length significantly because of the reflected object or the image in the display, as long as the image of the reflected object or the image in motion on the display, The imaging projected on the retina after passing through the lens in the eyeball can recognize the depth of field recognized by several layers of the retina, that is, the eye can clearly see the image or distinguish the movement of the image, but it is not necessary to quickly adjust the length of the eyeball to adapt to the image The movement is that the intraocular pressure will not rise. The distance between the virtual image of the non-transparent reflection 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 through a reflective surface 2 60, 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 passes through the eye lens Later, when the focal length adjustment of the eyeball lens is fixed on the reflecting surface, the imaging is performed on the multilayer structure of the retina. The eye "feels" through the retina to the image 4 1 2 before the eyeball retina, that is, the image exists in the retina. In front of the upper reflection, it is 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 2 60, the image 413 refracted by the crystalline lens will also fall on the surface of the retina. In combination with Figures 3b and 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 increase in intraocular pressure, image overlap or afterimage. The problem of the Keller effect is also an advantage of virtual image projection imaging. Please refer to FIG. 4, FIG. 5, and FIG. 6.
