Description of the Invention The invention relates to a stereoscopic display device, and more particularly to an autostereoscopic display device suitable for multiple people and multiple positions. A stereoscopic display device images two different perspectives of a scene on the left and right eye areas respectively, and thus the viewer generates parallax from the images of two different perspectives, and sees the stereoscopic display of the image. The current stereo display device technology uses two screens (such as RT screens). The generated images are polarized to generate left and right eye images with two different polarizations. The images are separated and projected at the positions of the two eyes, as in the technique mentioned in US Patent No. 4,649,425. Please refer to FIG. 1, which illustrates an autostereoscopic display system proposed in US Patent No. 4,649,425. The device contains two CRT screens 10 and 12, which are used to generate images, and the screen surfaces of the two screens 10 and 12 are respectively equipped with polarizers 14 and 16 for passing light of two different polarization directions, such as polarization. The polarizer 16 allows S-polarized light to pass through, and the polarizer 14 allows only P-polarized light to pass through. After that, the S-polarized light is reflected by the mirror 18 and passes through the beam splitter 20, and the P-polarized light is reflected by the beam splitter 20. Then, the S- and P-polarized light passes through the lens 22, the polarization devices 24a, 24b, and the lens 26. At this time, the polarizing devices 24a and 24b are polarizers that allow P-polarized light and S-polarized light to pass through, and the polarizing devices 24a and 24b can adjust the polarizing devices 24a and 24b by a tracking system. s position. Finally, the S- and P-polarized light are reflected by the reflector 28 and projected through 3 paper standards applicable_National Standard (CNS) A4 Regulation Orange (210X2974 ^ 7 (Please read the precautions on the back before filling this page) Ding Printed by the Central Laboratories of the Ministry of Economic Affairs, Shellfish Consumer Cooperatives 3656twf / 005 A7 3656twf / 005 A7 Printed by the Consumers' Cooperatives of the Staff of the Central Standards Bureau of the Ministry of Economics B7. 1 5. Description of the invention (>) The lens projection is located at 32 On the left and right eyes of the viewer. The left and right eyes of the viewer respectively receive the S- and P-polarized image information, and the parallax makes the viewer close the three-dimensional display of the image. In addition, the tracking device can track the viewer's Position, the position of the polarizing devices 24a, 24b can be adjusted at any time, so that the left and right eyes of the viewer can respectively receive the S- and P-polarized image information. In summary, the optical system of the conventional stereo imaging device is very Complex, including reflectors, beamsplitters, and many lenses. This design makes the overall structure of the stereoscopic imaging device too large, and it is difficult to achieve miniaturization. In addition, it is more difficult to fit the table In addition, the conventional technique uses two CRT screens to produce two images with different polarized light, which also causes a problem of complicated structure. Furthermore, the conventional stereo display device is very useful for only one viewer. A suitable system. However, if there are multiple people watching or each viewer is at a different position and distance, it is difficult for each viewer to view the stereoscopic display image. Therefore, the main object of the present invention is to provide An auto-stereoscopic display device achieves the effect of three-dimensional display with the most streamlined structural design. Another object of the present invention is to provide an auto-stereoscopic display device, which can be suitable for situations where multiple people watch and can automatically track the position and In order to achieve the above and other objectives of the present invention, a device is proposed. The device is briefly described as follows: Here is disclosed an autostereoscopic display device that includes at least one light.

Description of the Invention (Γ) 230 ”ordinary liquid crystal display panel 260 aperture switching device. For examples of liquid crystal switching panel, please refer to the first FIG. 2 is a schematic structural diagram of an autostereoscopic display device 2000 of the present invention, which includes at least a light source 210, a polarizing device 22, a liquid crystal panel 230, and an imaging device 240. After the light source 210 passes through the polarizing device 220, it is divided into two kinds of polarized light, such as P- and S-polarized light. The liquid crystal panel 230 may be a micro-polarized LCD panel, and the left and right eye images to be viewed are staggered and displayed on different micro-polarized horizontal or straight bars of the micro-polarized liquid crystal panel, for example, the left eye is displayed on P The polarizing part, the right eye is displayed in the S-polarizing part, the image-presenting device 240 presents a virtual image of the micro-polarized liquid crystal panel 230 behind the image-presenting device 240, and the polarizing device 220 presents a real image to the viewer 300 The left and right eye positions allow viewers to see the stereoscopically displayed image through parallax. The above-mentioned light source 210 may be a projection type point light source array or a long-type lamp tube. In addition, a light diffusion plate can be added before the light source 210 to increase the uniformity of the light source. The liquid crystal panel 230 may be a transmissive, reflective, or other type of liquid crystal panel in addition to the aforementioned micro-polarization type. The imaging device 240 is a screen portion, which may be a large lens, a fresnel lens, or a concave mirror. The above-mentioned polarizing device 220 has a tracking function, which can move left and right and back and forth (such as the X and Y directions in Figure 2), so it can track viewers at different distances so that they can all see 7 ( Please read the notes on the back before filling in this page) >.

In addition, one or more polarizers in this auto-stereoscopic display device can be configured, so it can be suitable for viewing by multiple viewers. Please refer to Figure 2A, which shows Figure 2 The structure of the medium liquid crystal panel 230. The micro-polarization type liquid crystal panel is a structure in which a plurality of P-type polarizers 230a and S-type polarizers 230b are staggered. Generally, a liquid crystal panel can only receive light of a certain polarization. Therefore, when the light emitted from the light source 210 is divided into P-polarized light and S-polarized light by the P-type polarizer 220a and S-type polarizer 220b in the polarization device 22, respectively, it will only penetrate 230a and 230b while reaching the view If the viewer's left eye and right eye 230a and 230b display the image of the left eye and the image of the right eye, respectively, the viewer will see the stereoscopic image through the parallax. The LCD panel 230 and the imaging device 240 The distance is smaller than the focal length of the imaging device 240, so the viewer's eyes can see the virtual image of the image formed on the liquid crystal panel; and the distance between the polarizing device 220 and the imaging device 240 is greater than the focal distance of the imaging device 240, so the polarization The light source (such as p_ polarized light and S-polarized light) is imaged at the position of the eyes of the closer with the real image and used as the aperture of the left and right eyes. In addition, the polarizer 220 is connected to a tracking device. The tracking device can track The position and distance of the viewer 300 can be adjusted by adjusting the position of the polarizing device 220 (X and Y directions as shown in the figure), so regardless of the position and distance of the viewer 300, the stereo image can be clearly seen. The example is to place the liquid crystal panel 230 on the light source 210 and the image 8 The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X.297 mm) --------- C—-(Please Read the notes on the back first Item #Fill in this page),?

Description of the invention (9) between devices 240. However, The liquid crystal panel can also be installed before the imaging device 240, that is, between the imaging device 240 and the viewer 300, as shown in Figure 3. In this case, the size of the image seen by the viewer 300 is liquid crystal. The size of the panel 23 ′. At this time, the liquid crystal panel 230 ′ is usually in close contact with the imaging device 240. Because the imaging device 240 does not affect the size of the image under this structure, the size of the imaging device (lens) 240 can be further reduced. Then refer to Figure 4. Because the light source 210 passes through the polarization device 22, it is divided into two kinds of light with different polarization directions, so the resolution of the image is reduced by about half. Therefore, if a polarization switching panel 250 is added between the liquid crystal panel 230 and the polarization device 220, it can compensate the originally lost resolution and improve the quality of the stereoscopic image. Please refer to FIG. 5, which illustrates a variation of the present invention. In this figure, three sets of polarization conversion devices 220, 222, and 2M are shown. Each of the polarization conversion devices 220, 222, and 224 includes a P-type polarizer 220a, 222a, 224a, and an S-type polarizer 220b. , 222b, 224b are used to divide the light emitted by the light source 210 into P-polarized light and S-polarized light. Each of the polarization conversion devices 220, 222, and 224 is individually coupled to a tracking device 'to track the positions and distances of the viewers 300a, 300b, and 300c, respectively, to adjust the positions of the polarization conversion devices 220, 222, and U4. Therefore, the present invention does allow multiple viewers to view stereo images simultaneously or at different locations.

As shown in Figure 6A, when 260a is "on" (light can pass), 260b is "off" (light cannot pass), and At this time, 230 "displays the left-eye image, followed by 260a" off "and 260b" on ", and 230" displays the right-eye image, so that the viewer can see the stereo image due to the parallax between the two eyes. In this method, the structure using a micro-polarization type liquid crystal panel, such as the above-mentioned Figures 2, 3, and 5, can be changed to a structure using an ordinary liquid crystal panel. The tracking device can use a dual-sensing tracking system, dual CCD system, or any other system that can track interactively, so that the polarization conversion device can move back and forth and left and right, as shown in the X and Y directions in the figure. Therefore, the present invention is characterized in that it only needs a liquid crystal panel, at least one polarizing device and an imaging device (such as a lens and a Fresnel lens, etc.) to achieve the purpose of stereoscopic imaging, so it has a structure Simple advantages. Another feature of the present invention is that the optical system is simple and the parts used are greatly reduced, so it is easy to achieve the purpose of reducing the volume, and it can also meet the requirements of the desktop stereo display. Still another feature of the present invention is that with multiple sets of polarizing devices and independent tracking systems, it can achieve the advantages of multi-viewers and stereoscopic viewing at different positions and distances. To sum up, although the present invention has been disclosed as above with a preferred embodiment, 10 (Please read the precautions on the back before filling out this page) Order Φ: This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) 3656twf / 005 A7 B7_, V.
