Description

A7 B7 V. Description of the invention (! [-, The technical field to which the invention belongs) The present Maoming is about an image display device, especially a contention-type or helmet-type battle & < heart image display device. [一[Previous technology] In recent years, 'a variety of audiovisual equipment and display devices have made rapid progress. In addition to this, lightness, thinness, shortness, and portability are also the development of displays. Wang Cheng' Among them, a new type of display device is a virtual reality. (Virtual H ty) technology 'Through the integration of various technologies, such as display technology, electricity technology, blindness technology and sound technology, etc., the original large-sized audiovisual equipment is smaller than the square inch and becomes a portable glasses type Projection display device. Although the weight of the flat-panel display is reduced, its size is limited by the weight of the material and the cost. It cannot achieve the effect of simultaneously enlarging the image size and being easy to carry. Therefore, the current display cannot meet the market pursuit of large size. Consumer demand for image display. Recently, many players are racing to see projection displays, especially glasses-type displays. Because of its small size, it can use the combination of optical elements to allow users to achieve the viewing effect of large-sized screens. It is generally expected that glasses-type displays can save the space of ordinary displays and greatly reduce the weight of displays with the same effect. Meet the needs of advanced audio-visual. However, although the current glasses-type projection display device is relatively light, it is still too heavy to be worn on the head. In the past, the eye-type display was mounted in front of the user's eyes with two small-sized CRT video tubes. The effect of enlarging the size is achieved by shortening the distance between the CRT and the eyes. However, this design has a large load on the user's head.

V. Description of the invention (And Kao Tian, Quan Qiang, is not practical. The general glasses-type projection display device used recently is a flat display device. Its principle is shown in Figure 1, which includes a liquid crystal ', >, and叩 110, two-way beam splitter 120, a polarizing beam splitter 130, a projection lens 140, and two flat mirrors or concave mirrors 150 and 160. The image provided by the liquid crystal display 11 is passed through the two mirror surfaces 150 people 16 60 / People reflect and project the image into the observer's eyes. However, the final image formed by this projection method is a real image. When used in close proximity, the lens will be pressed because the lens will bend. “Please see Figure 2a. Tu 2e, this is a schematic diagram of the effect of the known capital's Buller effect on the human eye. Just like the video recorder or camera used by the people at the same time, when the user tries to focus while holding the camera while moving, he will find the camera lens The focus has been adjusted after the month, because the camera must try to go to Dong Qingyan = which Shao Fen is the subject you want to shoot, the distance of the subject from the camera, etc. In order to focus sharply and take 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 at any time to adapt to different distances. As shown in Figure 2a, When the object seen by the eye is red and the image is stationary, the eyeball 5 and the crystalline lens 5 are maintained in a normal state, and then see FIG. 2b. When the real image 61 and the eyeball 501 are in a relative movement, the eyeball 5 〇1 In order to grasp the correct image, the length of the eye axis and the curvature of the crystalline lens 511 must be adjusted quickly. For example, the curvature of the crystalline lens 5 12 in the figure becomes smaller and becomes flatter, and the eye axis of the eyeball 50 is as long as Adapt to the curvature of the crystalline lens 512 and become shorter; or as shown in the diagram "The curvature of the crystalline lens 5 13 becomes larger and becomes thicker, and the axial length of the eyeball 503 becomes longer to accommodate the curvature of the crystalline lens 5 13; finally, as Tu Yisuo

V. Description of the invention (3 No, the crystalline lens 5 1 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 the conventional Doppler effect. And in the process of quickly adjusting the focal length, the blood vessels around the eyeballs circulate a large amount of blood, which will cause pressure on the eyeballs, and the focal length will be gradually and frequently adjusted. (The excessively high intraocular pressure caused by the lower eye will not only cause a distressed feeling to the human eye. In severe cases, there is a risk of retinal detachment. Therefore, this real image is also a device that is used in glasses-type display equipment. When the measurement time is extended (within several hours), the result will cause the observer's intraocular pressure to rise, which will cause dizziness and discomfort, and even severe retinal detachment, so it is not suitable for young children or patients with heart disease or hypertension. When projecting a real image for eyeball imaging, if the magnification 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 projection. 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's head is moved, the image caused by the Huiying and Doppler effects is very fuzzy or serious Shaking, so the display quality is not good, and the application field is not wide. Because a new display device is still needed in the heart field, it can effectively enlarge the image provided by the microcomputer and maintain high resolution, and its imaging method will not Squeezing the eyeball, even if it is close-up and prolonged for a long time. 1The heart does not cause an increase in intraocular pressure. The inventor is based on this, and in the spirit of active invention, urgent thinking = "monolithic refraction imaging display to solve the above problem" The "device" has been researched and tested until it is completed. This is the invention that benefited the world. (Please read the precautions on the back before filling in the blocks on this page.)

594049 V. Description of the invention (6) If the image on the reflective surface is in motion, because the eye is focused on the reflective surface only, that is, the eyeball does not need to adjust the focal distance significantly due to the reflected object or the image movement in the display, as long as the reflective 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 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 reflecting surface 2 60, the eyeball will automatically adjust so that the non-penetrating reflecting surface passes through the water and the body is imaged on the retina, and the virtual image 44 formed by reflection on the reflecting surface passes through the eyeball. After the lens, the lens will be imaged on the multilayer structure of the retina with the lens's lens focal length adjusted and fixed on the reflecting surface. The eye "feels" through the retina until the image 412 falls before the eye retina, that is, "feels" that the image exists on the retina In front of the 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 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 4 丨 3 refracted by the crystalline lens will also fall on the surface of the retina. In combination with Figures 4b and 4c, it can be explained that even if the object or image has relative movement, it can be known from the above description that the eyeball does not need to adjust the focal length during virtual image movement, 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. China (flUcNS) A4 size (210 X 297 mm) 12

Therefore, it can be determined whether the observer only needs to observe. Image, or want to see the external environment at the same time. In addition, since the concave lens is used as the virtual image imaging unit 250 in this embodiment, strong ambient light (such as sunlight) outside the user ’s line of sight is transmitted through the lens. In the case of a concave lens, the angle of deflection and refraction is large after entering the concave lens. Most of the sunlight entering the concave lens will not enter the user's eyes because the angle of refraction is large, so this embodiment uses refraction to form a virtual image, which can reduce ambient light. The interference of the image is relatively enhanced. When viewing the received image or information, it is possible to observe the dynamics of the external environment without affecting the contrast of the image or information. The scope of application of this image display device is general, for example, for driving aircraft, Drivers of ships, automobiles, locomotives, and other vehicles can perform multiple tasks simultaneously and perform driving simultaneously.
