In addition to strengthening the power, light, thin, short and convenient to expand the band is also the development of the king of the winter display. One of the emerging display devices is virtual Reality (^ 1 "" reality) technology, through the integration of various technologies, such as display technology, computer technology, sensory technology and sound technology, etc., reduce the original large-scale audiovisual equipment to a square inch, and become portable Glasses-type projection display device. Although the general < flat panel display has reduced weight, its size is limited by the weight of the material and cost, and it cannot simultaneously enlarge the image size and easily carry the V < efficiency. Therefore, the current display cannot meet the market demand for large-size movies and displays. Recently, many industry players have been optimistic about projection displays, especially glasses-type displays. Because of their small size, they can use a combination of optical components to allow users to 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 erected in front of the user with two small-sized CRT image tubes, and the size of the paper was reduced by shortening the distance between the CRT and the eyes. ) (Please read the precautions on the back before filling out the columns on this page) Binding ----- Order ----- 0m. 200409943 A7 -________ B7 V. Description of Invention (2) " ^-inch effect . However, this design is not practical for the heavy load on the user's head and strong radiation. The general glasses-type projection display device commonly used here is a flat display device. Its principle is shown in Figure 1. It includes a display 110, a two-way beam splitter 120, a polarized beam splitter 130, and a projection lens 1440. Two plane mirrors or concave mirrors 15 and 160. The image provided by the M liquid crystal display 110 is reflected twice by the two mirror surfaces and 160, and the image is projected into the observer's eyes. However, the final image formed by this type of projection is a real image. When used in close observation, it will force the lens of the eye to bend and press the eyeball; please refer to Figures 2a to 2e. Schematic of the effect. 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's lens has been gradually refocusing after the magic. This is because the camera must try to recover Which part is the subject you want to shoot, the distance of the subject from the camera, and so on, you can only focus properly to get 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 FIG. 2a, when the image of the object seen by the eye is a still real image 6, the eyeball 5 and the crystalline lens 5 丨 are maintained in a normal state; then please refer to FIG. 2b, when the real image 6 丨 is in a position opposite to the eyeball 5 〇 丨In movement, the eyeball 501 must quickly adjust the length of the eye axis and the curvature of the crystalline lens 5 in order to capture the correct image. For example, in Figure 2c, the curvature of the crystalline lens 512 becomes smaller and becomes flatter, and the eyeball 502 The eye length is shortened in order to adapt to the curvature of the crystalline lens 51 2; or as shown in Fig. 2 (1, the curvature of the crystalline lens 513 becomes larger and becomes thicker, and the axis of the eyeball 503 is ______6 — This paper scale applies to China Standard (CNS) A4 specification (21 × 297 mm) ------- V-Shang (Please read the precautions on the back before writing each page 橺) —I II —ϋ ϋ— -r · mmMi — ϋ --Bi, a Hu 200409943 A7

Description of the invention (3) The length becomes longer in order to adapt to the curvature of the crystalline lens 5 1 3; Finally, as shown in FIG. 2e, the crystalline lens 5 1 4 is rounded to a correct curvature, and the eye axis is adjusted to the state of 504 accordingly. . During the adjustment process, since the object moves faster than the eyeball adjustment speed, there will be an afterimage 62, which is the conventional Doppler effect. In addition, in the process of rapid focus adjustment, a large amount of blood flowing through the microvessels around the eyeball will cause pressure on the eyeball. Too high intraocular pressure caused by long and frequent focus adjustment will not only cause uncomfortable feeling to the human eye. In severe cases, there is a fear of retinal detachment. Therefore, if this real image projection device is used in a glasses-type display device, the observation time (within a few hours) will be prolonged, which will cause the observer's intraocular pressure to increase, and τ ^ will cause halo The symptoms of dizziness and discomfort can even lead to retinal detachment, so it is not suitable for young children or those with heart disease or hypertension. When projecting a real image for eyeball imaging, if its magnification is to be increased, f should 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. Not practical. In addition, the display device that forms a projection real image in the eye is used; when the head is moved, shadows caused by ghosts and Doppler effects are blurred or severely shaken, so the display product f is not good and the application field is not wide . ^ Therefore, a new display device is still needed on the market. It can effectively enlarge the image provided by Mingxinxin and maintain high resolution. Its imaging method is not ^ pressing the eyeballs. Causes symptoms of increased intraocular pressure ^.

Explanation of the invention (4 ^ --- As a result of this, the spirit of active invention, based on the spirit of active invention, urgently thinking about a kind of "can do" 4th question "" Configuration improved dual-body projection image display equipment " Scholars and researchers will continue to complete this invention that will benefit the world. [III. Summary of the Invention] The main purpose of the invention in January is to provide an improved dual-body projection shadow = display device, which is effective. Enlarge the image provided by the micro display, occupy two rooms 2, maintain the image resolution, avoid stress on the eyeball, extend the use of low material costs, low power consumption, easy magnification adjustment, high image field contrast, reduce Doppler and The ghost effect is suitable as a spectacle helmet display device. ^ In order to achieve the above-mentioned purpose, the improved dual-body projection image head device of the present invention includes: two display units, each for providing an image; a refractive lens group Is located on one side of the display unit, and is used to respectively deflect light transmitted or reflected from the display unit; and two virtual image imaging lens groups are respectively located in the phase of the birefringent lens group. On the other side of the display unit, the light transmitted by the refraction lens group is deflected, and the virtual image imaging lens group converts the image formed by the refraction lens group into a virtual image; wherein the refraction lens group is located in the Between the display unit and the virtual imaging lens group; and the 2 images displayed by the display unit are deflected through the refractive lens group to form a real image inverted from the original image, and then converted into an original image by the virtual imaging lens group The virtual image of an inverted image. 1 200409943 V. Description of the invention (5) The above-mentioned display 7F device can be applied to any image, picture, symbol and text display application or equipment, preferably for information presentation of televisions, computers, and printers.

FIG. 3 is a conventional projection system In the case of the real image 4 being projected, under the condition that the eye is regarded as a real image, the eye must correctly adjust the sound 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 It will bring pressure to the eyes. Fig. 4a ^ c shows the case of the virtual eye of the present invention. In this case, when the imaging lens group (concave mirror) 260 is transparent, it is projected by the display unit (not shown). The real image 42 will be formed after the imaging lens group 26 () — virtual confusion, and when the human eye observes the virtual image of the reflective surface, the eyeball adjusts its focus on the reflective surface, so that when the human eye views the virtual image of the reflective surface , The eye does not need to adjust the distance, 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 facing the eye is only the reflecting surface, that is, the eyeball does not need to be based on the movement of the reflecting object or the image in the display.

[4. Implementation Modes] In order to allow the reviewing committee members to better understand the technical content of the present invention, specific examples are described below. Embodiment 1 Please refer to FIG. 8. FIG. 8 is a cross-sectional view of the inside of a glasses-type image display device according to the present invention. This embodiment includes a housing, which contains two WQs microdisplays 21o and 211, two light sources 215, two non-equal curvature convex lenses 22o and 22 1 (refractive lens group), and two concave imaging areas 230 that are partially mirror-finished. And 231 (virtual image imaging unit). Among them, the two micro-displays 210 and 21 and the light source 2 15 are placed at both ends of the housing. The two micro-displays are 210 and 211, and convex lenses 220 and 221 are respectively disposed below the convex lenses 220 and 221. Below 221 are virtual image imaging areas 23 and 231, respectively. A diffractive sheet may be added between the displays 210 and 211 and the convex lenses 220 and 221 to increase the half-brightness angle of the incident light. In addition, the convex lenses 2 2 0 and 221 are arranged so that the incident light from the displays 210 and 211 and the convex lenses 2 2 0 and 2 2 1 form an angle of 30 degrees with the normal of the incident surface of the reflection unit. Γ 13 This paper size is applicable to China National Standard (CNS) A4 specification (210X297 mm) (Please read the precautions on the back before filling in the columns on this page) Packing ------------------- 200409943 A7 B7 5 、 Explanation of the invention (10) • Equipment · 1 (Please read the precautions on the back before filling in this page.) The light emitted by the display 2 1 0 and 2 1 1 goes down to the convex lenses 220 and 221, respectively. The convex lenses 220 and 221 convert the original image into an inverted magnified real image, and then pass through the concave mirrors 2 30 and 2 31 to magnify again to form an inverted magnified virtual image. Please refer to FIG. 9. FIG. 9 is a side view and a virtual image imaging principle inside the glasses-type image display device of the present invention. This figure shows that the #image 2 7 1 series provided by the display 2 丨 is located somewhere between the focal length of the convex lens 2 2 0 and twice the focal length 'and according to the principle of convex imaging, the convex lens 2 2 〇 On the other side, a doubled focal length will form an upside-down magnified real image 2 7 2 (if an screen is placed on this, you can see an upside-down magnified real image). The magnification of the real image 272 depends on the image. 27 丨 the distance from the convex lens 22o, the closer the distance, the higher the magnification. The real image 2 72 must fall within the focal length of the concave mirror 230. Similarly, according to the imaging principle, an enlarged virtual image 2 7 3 will be formed on the other side of the concave mirror 23 °, and the magnification of the virtual image 2 7 3 will also be Depends on the distance between the real image 272 and the concave mirror 23 °. It should be noted that in this embodiment, there is no screen between the convex lens 22o and the concave mirror 23o, and the magnified real image formed by the convex lens 220 cannot be seen; therefore, the phenomenon we see is that the light converges through the convex lens 2 2 o Fold to the concave mirror 2 3 0, and then deflect the concave mirror 2 3 0 and project it into the observer's eyes. However, the light is focused on the eyeball into a real image, so the eye will extend the light to the concave mirror 230 and form a real image 272. A magnified virtual image with the same direction 273 〇 Those familiar with this technical field will recognize that in order to achieve the above-mentioned imaging strategy, the child display 210, the convex lens 22 and the concave mirror 23 must be formed.

Description of the invention (12) The imaging principle and magnification of the lens are the same as those described in the first embodiment. However, after changing to a concave lens, the observer can see the external environment at the same time when observing the image. And because the device of the present invention forms a virtual image by refractive projection, when a concave lens is used as the virtual image imaging unit, the light transmitted through the concave lens has a large refractive deflection angle, so it is about waiting for the user to stand in front of the user and the line of sight. People with glasses-type displays will not see the images and data that the user is using or receiving, and they have good confidentiality and privacy, and will not interfere with others around them. Embodiment 4 The structure of this embodiment is roughly the same as that described in Embodiment 1, except that the virtual image imaging unit is converted from a concave mirror 23 to a combination of a concave mirror and a concave lens; the imaging principle and magnification are the same as those in the embodiment.丨 described. The mirror can be swapped up and down, so it is up to the observer to decide whether to observe only the image or to see the external environment at the same time. Embodiment 5 The structure of this embodiment is substantially the same as that described in Embodiment 1, except that the virtual image imaging unit is formed by converting a concave mirror 23 into a mask and a concave lens; the imaging principle and magnification are the same as those in the embodiment. The first and second masks can be swapped up and down, so it can be decided by the observer whether to only observe the image or to see the external environment at the same time.

Description of the invention (13) Please refer to FIG. 11. The structure of this embodiment is substantially the same as that described in embodiment 3, except that the solid-state liquid crystal layer is installed on the outside of the outer cover 310 to shield the 350 and-polarized light. Lens 360; its imaging principle and magnification are as described in embodiment i. However, the semi-solid liquid crystal layer becomes transparent when the power is turned on, so that external light can pass through, and the user can receive the image while receiving the image from the display and Monitor the surrounding environment. When the user turns off the power of the liquid crystal layer mask, the mask covers the light outside the boundary, and the information or image is received without external interference. Therefore, it can be determined whether it is transparent or not. As a '^ lighthouse *', the use of ψψ7 is possible. Therefore, depending on the needs of the observer, it is possible to decide whether to only observe the image or to see the external environment at the same time. In addition, this embodiment uses a concave lens as a virtual image. Dan Fan is a strong light that is directed towards the outer boundary of the user's line of sight (for example, when the solar magic is transmitted into a child concave lens, the angle of deflection and refraction after entering the concave lens is large, and the large angle of sunlight entering the concave lens is because the angle of refraction is large, and Does not shoot into the user's eyes, so this embodiment uses refraction to form a virtual image, which can reduce the interference of ambient light, and relatively strengthen the shadow silly ^^ ^ ^ for lack of image contrast. It can also be used for viewing images or shells. Observe the dynamics of the external environment without affecting the image or information comparison.

This kind of glasses-type image display device using the virtual image imaging principle will not cause eye pressure, even for a long time Use, there will be no dizziness in a few hours, it is a major breakthrough in today's glasses or head-disk image display technology. The present invention uses the formation of a virtual image on the eyeball, so when the user's head moves, The image blur is reduced due to the Doppler effect and ghost effect. In addition, since the invention uses refracted light to form a virtual image in the user's eyeball, only the virtual image imaging lens group or the refractive lens group needs to be adjusted when the image is enlarged. Such as convex, mirror) distance, angle and even curvature can be completed, the adjustment method is simple and early, and takes up little space. Compared with the traditional projection display device that forms a real image on the user's eyeball and requires a large space, it has the relative advantages of simplified operation and large flexibility in space f. Furthermore, since the present invention uses a refracted light to form a virtual image on the user's eyeball, the contrast of the imaging is high, the darkroom effect is large, and it is less affected by the ambient light. Device, better image quality. When the user uses it, the surroundings of non-users, because the image is refraction imaging, so the light refraction angle of the virtual image imaging environment group of the agency is large, it will not affect other people around the height of the user's line of sight, the interference is relatively low. In addition, since the image display device of the present invention uses a micro-display, the unit (concave mirror, concave lens, or plane mirror) and the refractive lens group (convex lens) = the curvature can achieve the effect equivalent to magnifying the screen in front of the user's eyes. However, the various optical elements used by it have the advantages of light weight and small size, low material cost, low power consumption, easy to carry, great flexibility in use, and can reduce production costs, which is quite in line with market demand. 1 This paper rule applies to Chinese national standards (210x = mm) (please read the precautions on the back before filling in this page).
