Explanation of the invention ~ '--[I. Technical field to which the invention belongs]' The present invention relates to an image display device, especially an image display suitable for glasses or helmet type Device. [I. Prior Technology] In recent years, various audiovisual equipment and display devices have made rapid progress. In addition to enhanced functions, thinness, lightness, shortness, and portability have also become the mainstream of display development. One of the emerging display devices is Virtual Reality. (Reality) technology, through the integration of various technologies, such as display technology, computer technology, sensory technology and sound technology, will make the original large-sized audio-visual equipment smaller than the square inch, and become a portable glasses-type projection display device. Although the flat panel display of Xuzhou has reduced weight, its size is limited by the weight of the material and the cost. It cannot simultaneously enlarge the image size and easily carry the effect of f. Therefore, the current display cannot meet the market demand for large-size image display. Recently, many industry players are optimistic about the projection display, especially the glasses-type display, because of its small size, but can use the combination of optical components, so that users can achieve the viewing effect of large screens. It is generally expected that the glasses-type display can save the space occupied by the general display and greatly reduce the weight of the display with the same effect to meet the needs of advanced audiovisual. However, although the current glasses-type projection display devices are light in weight, they are still too heavy to be worn on the head. In the past, the glasses-type display was mounted in front of the user's eyes with two small-sized Cr τ image tubes, and the effect of enlarging the size was achieved by shortening the distance between the CRT and the eyes. However, this design has a large load on the user's head. , ________ 5 This paper size applies to China National Standard (CNS) A4 specification (210X297 mm) '----- Loading --------- Order ----- (Please read the precautions on the back first (Fill in the columns on this page again) 580582 V. Description of the invention (2) The wheel ray is strong and not practical. The conventional display device known as the general glasses-type projection display device is used. Its principle is as follows: Two-way beam splitter 120, a polarized beam split; uo, a projection lens 140, and two flat mirrors or concave mirrors 150. 160. The image provided by the professional crystal display 11 () is reflected twice by the two mirrors and 160, and the image is projected in the observer's eyes. However, the final image formed by this projection method is a real image. When used at close range, it will force the lens of the eye to bend and compress the eyeball; please refer to Figures 2a to 2e. The schematic. Just like many video recorders or cameras used by many people at the same time, when users try to focus while holding the camera while moving, they will find that the camera lens has been adjusted after it has been adjusted. This is because the camera must try to go to Dong Qingyu. Which parts are the subject you want to shoot, the distance of the subject from the camera, etc., can you focus correctly and shoot a clear image. Human eyes are just like the lens of a camera. You must quickly adjust the curvature of the lens and the length of the eye axis to adapt to scenes at different distances. As shown in Figure 2a, when the image of the object seen by the eye is a static real image 6, the eyeball 5 and the crystalline lens ^ are maintained in a normal state; then please refer to Fig. 2b, #Real image 61 and the eyeball 5 () 1 are in a relative movement. In order to grasp 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 the figure "the curvature of the crystalline lens 5 12 becomes smaller and becomes flatter, and the eye axis of the eyeball 502 is longer Shortened to accommodate the curvature of the crystalline lens 5 12; or as shown in Figure 24, the curvature of the crystalline lens 513 becomes larger and becomes thicker, and the axial length of the eyeball 503 is longer to accommodate the curvature of the crystalline lens 5 1 3; finally As shown in the figure "All paper sizes are in accordance with Chinese National Standards (CNS) A4 specifications (210X297) (please read the precautions on the back before filling in the columns on this page).

Description of the invention (3 π, the crystalline lens 51 4 is adjusted to a correct curvature, and the eye axis is also adjusted to the state of 504. During the adjustment process, because the object moves faster than the eyeball adjustment speed, Therefore, there will be an afterimage 62, which is known as the Doppler effect. In the process of quickly adjusting the focus, the blood vessels around the eyeballs circulate a large amount of blood, which can cause pressure on the eyeballs, and adjust the focal length for a long time and frequently. The excessively high intraocular pressure caused not only will cause the human eye to have two or two feelings. In severe cases, there is a risk of retinal detachment. Therefore, if this real image projection device is used in a glasses-type display device, the observation time (several hours The result of elongation will cause the observer's intraocular pressure to rise, causing dizziness and discomfort, and even severe retinal detachment, so it is not suitable for young children or those with heart disease or hypertension. Projected real images If the magnification of the eyeball imaging is to be increased, the distance between the projection lens group and the eyeball needs to be lengthened, so if you want to increase the image magnification, you need to increase the investment. The space occupied by the system is not practical in practice. In addition, the display device that forms a projected real image in the eyes, when the user moves the head, the image will be blurred or serious due to ghost images and the Doppler effect. Shake, so the display quality is not good, and the application field is not wide. Therefore, a new display device is still needed in the market, which can effectively enlarge the image provided by the micro display and maintain high resolution. Its imaging method will not be C: L eyeballs, even if used at close range and for a long time, will not cause the symptoms of increased intraocular pressure. The inventor therefore, based on the spirit of active invention, urgently thinks about a "monolithic birefringent imaging display" that can solve the above problems.

Description of the invention (ό) The image of the image projected on the retina after passing through the lens in the eyeball can be the depth of field recognized by several layers of the retina, that is, the eye can clearly see the image or distinguish the motion of the image , But it is not necessary to quickly adjust the length of the eyeball with the image to adapt to the movement of the image, so that the intraocular pressure will not increase. The distance between the virtual image of the non-transparent reflection surface in the eyeball can be roughly explained in Figs. 4b and 4c. 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 passing through the lens to the retina, and the virtual 44 image formed by reflection on the reflective surface passes through the eye lens Later, with the focus adjustment of the ocular lens fixed on the reflective 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 eye retina, that is, the image exists in the In front of the retina reflection, it is between the crystalline lens and the retina, as shown in Figure 4b, and after it is transmitted to the brain, the virtual image is seen before the salty reflection 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 413 after being refracted by the crystalline lens will also fall on the surface of the retina. In combination with Figures 4b and 4c, you can explain the relative motion of the object or image. From the above description, it can be known that when the virtual image is moved, the eyeball does not need to adjust the focus, 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. Next, referring to FIG. 5, FIG. 6, and FIG. 7, these three figures are schematic diagrams of the refractive lens group used in the present invention compared with the conventional art. FIG. 5 is a conventional direct projection lens using a convex lens 170. Since the light path of the external light source 丨 800 is the same as the light path direction of the projection image of the display unit 190, the external light source applies the paper size to the Chinese national standard.

Description of the invention (7) It will form a mirror m reflection image for the projected image ... 'Figure 6 uses a concave surface and a cat _ m ~ system ~ In this figure, the light of the external light source i 80 == the light of the Xinqing projected image The diameter is also the same, so it will cause interference; FIG. 7 shows the use of refraction imaging in the present invention, in which there is a clear space between the (= image lens group) 172 and the display unit 19, and two external light sources 18. The light path refracted by the convex lens 172 is not the same as the light path of the projected image of 190. It does not interfere with each other and can form a good darkroom effect, improve the contrast of the image, and the refractive lens system of the image display device. The virtual image Γ silly-refracted is reflected by the reflection unit to form an inverted real image. After that, the real image will pass the car group: Jia A and t70 to form a virtual image. The refraction mirror of the image display device of the present invention has the function of “M and magnified image” to deflect the light that is transmitted or reflected from each other to form—the magnified second image inverted from the original image = the virtual image imaging lens group will The image formed by the refraction single S refraction lens group is converted into an inverted virtual image, preferably an inverted magnified virtual image; upon request, the distance between the image reflected by the reflection unit and the refraction lens group is equal to the focal distance of the refraction lens group and two Between focal lengths. According to the invention, the refractive lens group of the image display π device is unlimited. It can be any conventional refractive lens, and is preferably a condenser lens group, and more preferably—convex lens, non-equal curvature convex, mirror or two-piece Convex lens. The curvature of the two single-convex lenses may be the same or ^, and it is preferable that the curvatures of the two single-convex lenses are different. The image display device of the present invention < the range of the angle formed by the incident light of the self-reflecting unit and the refractive lens group and the normal of the incident surface of the reflecting unit to form an angle Υ is preferably greater than.

[Fourth, the implementation mode] In order to allow the #review committee to better understand the technical content of the present invention, the preferred specific embodiments are described below. (Embodiment 1) Referring to Fig. 8, Fig. 8 is a cross-sectional view of the inside of a glasses-type image display device of the present invention. This embodiment includes a housing containing two l_cos microdisplays 210 and 2U, two light sources 215, two Mitsubishi mirrors 22o and 221 (reflection units), and two non-equal curvature convex lenses 23o and 23 1 (refraction Lens group), and two concave mirrored areas 240 and 241 (virtual imaging unit). Among them, the two micro-displays 2 1 0 and 2 1 1 and the light source 2 1 5 are placed at the center of the housing, and the other two sides of the two micro-displays 2 丨 0 and 2 丨 丨 are respectively provided with three稜鏡 2 2 0 and the triangular prism 2 2 1, so that the two micro-displays 2 1 0 and 2 1 1 are not between the two triangular prisms 2 2 0 and 2 2 1. Convex lenses 230 and 231 are respectively disposed below the three lenses 2 2 0 and 221, and virtual image imaging areas 240 and 241 are respectively provided below the convex lenses 230 and 231. The convex lenses 230 and 231 are arranged so that the incident light from the prisms 220 and 221 forms an angle Y of 30 degrees with the convex lenses 2 30 and 2 31 and the normal of the incident surface of the reflection unit. 13 This paper size applies to China National Standard (CNS) A4 (210X297 mm) (Please read the precautions on the back before filling in the columns on this page). F ----- Order --------- 580582 A7 B7 5. Description of the invention (10) The light emitted by the displays 210 and 211 enters the prisms 220 and 221 to the left and right respectively. After that, it is reflected to the convex lenses 230 and 231 to convert the original image into an inverted magnified real image, and then passes through the concave mirrors 240 and 241 to magnify again to form an inverted magnified virtual image. Please refer to FIG. 9, which is a side view of the interior of the glasses-type image display device of the present invention. This figure shows that the Sanya 220 will refract and refract the image displayed on the L-COS micro-display to the convex lens 2 30, which is the image 2 7 1, and the image 2 7 1 will fall on the convex lens 2 3 0 Somewhere between the focal length and twice the focal length, and according to the principle of convex lens imaging, an upside-down magnified real image will be formed outside the double focal length on the other side of the convex lens 2 3 0, and the left and right directions will not change. 2 7 2 ( If there is a screen placed here, you can see an inverted magnified real image). The magnification of the real image 2 7 2 depends on the distance between the image 2 7 1 and the convex lens 2 30. The closer the distance, the higher the magnification. The real image 2 7 2 must fall within the focal length of the concave mirror 2 40. Similarly, according to the imaging principle, an enlarged virtual image 2 7 3 will be formed on the other side of the concave mirror 2 4 0, and the virtual image 2 7 3 The magnification also depends on the distance between the real image 272 and the concave mirror 240. It ’s worth noting, 'In this embodiment, there is no screen between the Λ lens 2 3 0 and the concave lens 2 4 0'. The magnified real image formed by the convex lens 2 3 0 cannot be seen; therefore, the phenomenon we see is that the light passes through The convex lens 230 converges to the concave mirror 240, and then is projected into the observer's eye by the concave mirror 240, but the light cannot be focused on the eyeball into a real image, so the eye will extend the light to the concave mirror 240 and form a direction with the real image 272.

Description of the invention ( 11), thermal technology, those skilled in the art can recognize that in order to achieve the above-mentioned imaging spectrometer 'child triangle prism 220, convex lens 23 and concave lens 24 must be formed, the relative position of the special I' so that the image 271 can fall on the convex lens The focal length of 23 ° is between twice the focal length and the image 272 can fall within the focal length of the concave mirror 24 °. The above-mentioned image display device can be selectively combined with a hearing device as shown in FIG. 10. The above-mentioned image display device 3 2 0 can be combined with a glasses-type outer cover 310 and an inner cover 3 40 and assembled with a headphone 3 30 to form a unitary glasses-type audiovisual equipment. The audiovisual equipment can be connected to a microprocessor such as a computer or virtual reality as the display device of the computer, or connected to a training machine (such as a simulator) to simulate training, or connected to a video system for remote communication, learning, conferences, For monitoring, it can be used as the information display and environment display of the 4 driving vehicle, or as the display device of the virtual game. Embodiment 2 The structure of this embodiment is roughly the same as that described in the embodiment 丨 except that it is in the virtual image. The imaging unit 240 is replaced with a concave mirror by a flat mirror. In this way, the formed image is only refracted and enlarged once by the convex lens 23, and then converted into a virtual image by a plane mirror. The plane mirror has no magnification effect. However, the magnification and effect of Bayer's erroneous structural image can still be accomplished by the lens 230 that refracts light.

Description of the Invention (12) The structure of this embodiment is roughly the same as that described in Example 1, except that the virtual image imaging unit 24 is replaced by a concave mirror with a concave reflection with 40% reflectance. The imaging principle and The magnifications are as described in the embodiment. However, after being replaced with a concave through button, the observer can simultaneously see the outside ring while observing the image. The device of the present invention is a virtual image formed by refraction projection. When a concave 1¾ is used as the virtual image imaging unit, the light transmitted through the concave lens is transmitted. ， Because the angle of deflection of 2 shots is large, people who are standing in front of the user and have a few lines of sight, etc., will not see that the user is using or receiving "Images and data, which Confidentiality and privacy without disturbing others around you. Example 4 "Example: The fabrication is roughly the same as that described in Example 1, but the difference is that the image is straight. ^ Imaging Shanfan 24o is a combination of a mirror and a concave lens; the reasoning and magnification are the same The embodiment is as described in Embodiment 1. The mirror can be mounted on the platform: can be determined according to the needs of the surveyor whether to observe only the image, or want to see the external environment at the same time. Embodiment 5 is basically the same as that described in embodiment 1, but different The second is: " Zhaofan 240 is a combination of a mask and a concave lens; its large magnification is as described in Example 1. The mask can be up and down, and can be determined according to the needs of the observer, whether to observe only the image, or It is the same when seeing the external environment.

Description of the Invention (13) Example 6 Please refer to Figure IX. The structure of this embodiment is roughly the same as that described in Example 3, except that the virtual image imaging unit 240 is externally equipped with a half solid-state liquid crystal layer mask. 350 and a polarizing lens 360; the imaging principle and magnification are the same as in the embodiment 丨However, the semi-solid liquid crystal layer is covered by the mask; when the power is turned on, it becomes transparent, allowing the external light to pass through, and the user can receive the image and monitor the surrounding environment while receiving the video image. When the user closes the liquid: layer The power of the mask, the mask covers the light outside the boundary, and receives information or images in order to be free from external interference. Therefore, it can be powered on or not to determine whether it is transparent or opaque. It can be used as a grating. According to the needs of the observer, it is decided whether to observe only the image or to see the external environment at the same time. In addition, since the concave lens is used as the virtual image imaging unit 240 in this embodiment, the environment is brighter than the user's line of sight (such as sunlight). When transmitting into the concave lens, the angle of deflection and refraction is large after entering the concave lens. Most of the sunlight entering the concave lens has a large refraction angle and will enter the eyes of the user. Therefore, this embodiment uses refraction to form a virtual image, ' It can reduce the interference of ambient light and relatively enhance the contrast of the image. It can not affect the contrast of the image or information when viewing and receiving the image or information. Next: Observe the dynamics of the external environment at the same time. This image display device is widely used. For example, for the driver of a plane, boat, car, locomotive, etc., he can perform multiple tasks and perform multiple tasks. Drive on. '580582

This kind of shore H can be used for a long time, counting the balls ... Nowadays, glasses-type or head-type 4 images are like: eyeballs, so when the user's head moves, the image: force effect and ghost effect caused by image blur reduction . In addition, since the Ming system uses the refracted light to form a virtual image on the user's eyeball, the magnified image only needs to be adjusted for the virtual image imaging lens group or the refractive lens group (such as convex distance, angle, and even curvature), and the adjustment method is simple. Small. Compared to the traditional formation of a real image in the user's eyeball, a two-space large projection display device has the relative advantages of simplified operation and space. Furthermore, since the invention uses refracted light, the spring field forms a virtual image to the user. Eyeballs, so the contrast of imaging is high, the effect of 2 is large and it is less affected by the ring material, compared with the traditional projection display device that will be like the eyes of 2 users, the image quality is better. For non-users, because the image is shot, the angle of refraction of the light through the imaging environment group is large, and it will not affect other people around the user, and the interference is relatively low.
