To observe a stereoscopic image that can be connected to t, the object must project at least 37 degrees of parallax in the eyes of the soil. In the conventional art, in order to observe the stereoscopic image, there are many methods proposed and many are used. The projector shoots images with different viewing angles with different polarized directions, and then uses special lenses to project images with parallax into the eyes to produce a three-dimensional effect, but this type of universal shooting is difficult and the audience must wear special Glasses can only be used to view stereoscopic images. There are also different color lights that cause parallax of the image, so as to integrate the body image in the eyes, but this method except the image color π is not easy to change, and the audience must wear glasses. Disadvantages of viewing stereoscopic images. In order to be able to observe stereoscopic images and the viewer does not need to wear glasses, they can observe from multiple viewpoints at the same time. Stephen P. Hines U.S. Patent No. 5 43〇474 proposes a display system that can simultaneously observe stereoscopic images from multiple viewpoints, as shown in Figure 1. The images that should be observed at various viewing angles are simultaneously output in different divided areas of the LCD panel Each segmented area uses a lens to project the image on the screen composed of F Γ esnd lenses. The observation position and the lens g-port Fresnel lens form a conjugate relationship, so each view can be viewed at each viewing position. This system uses presne 丨 lens, so it is not easy to enlarge the area. And each angle of view uses one lens, not only the number of lenses, corresponding to the lens positions above and below, the division of the LCD panel must be staggered, such as The labels marked with 5 and 6 in Figure 1 also cause the LCD panel to not be fully used.

Description of the invention (2) What is wrong, the purpose of the present invention is to provide a multi-viewpoint automatic The body display system makes the two screens share a lens, so it can reduce the number of lenses required, and therefore the lens is not equipped with conflicts, so the LCD panel can be divided into multiple areas evenly, which can be fully utilized Each portrait unit on the liquid crystal panel. Another object of the present invention is to provide a multi-viewpoint autostereoscopic display system using split screens, which can use a reflective cylindrical lens plate to display images. It is easy, so the display panel can be enlarged.

For a description of the embodiments, please refer to FIG. 2. The multi-view autostereoscopic display system using split screens of the present invention includes the following architectures: a light source 10, a collimating lens 12, a liquid crystal panel 14, a convergence lens 16, and a Kosters prism 18 The projection lens 20 and the biconvex cylindrical mirror plate 25 include a diffusion plate 25 'sandwiched between the biconvex cylindrical mirror plate 25, and a viewing window 27. The aforementioned light source 10 includes six projection light sources, which are arranged in two columns and three rows in a matrix. And the aforementioned projection light source may be composed of a bulb and a parabolic mirror or a rounded mirror. The collimating lens 12 and the converging lens 16 form a focusing system for forming the light beam through the collimating lens to form parallel light, which then passes through the liquid crystal panel 14 and converges the image on the liquid crystal panel 14 The lens 16 converges, passes through the Kosters prism 18, and is projected onto the projection lens 20. The aforementioned Kosters prism 18 is a positive dihedral cylindrical prism composed of two right-angle prisms. Among them, a polarized beam splitter is located between the interfaces of two right-angle prisms. _ Please refer to FIG. 3, which illustrates the spatial arrangement relationship between the liquid crystal panel 14 and Kosters 稜鏡 18 < As can be seen from the figure, the collimator lens 12, the liquid crystal panel 14, and the convergent lens 16 are also areas including a matrix arrangement of two columns and three rows. At the same time, there is a one-to-one correspondence between the areas of the collimator lens 12, the liquid crystal panel 14, and the convergence lens 16 and the six projection light sources of the light source 10.

Invention description (above and below the four interfaces. Please refer to Figure 4, the projection light sources in the upper and lower columns are not located on the optical axis of the lens group, so the light beam After passing through the collimating lens 12 and the liquid crystal panel M, the upper and lower columns of light beams will travel in different directions away from the optical axis, and one column of light beams will pass through the half-wavelength plate 15 to change its linear polarization direction. Then, after passing through the convergent lens 16, it is incident on the ruler 04 ^ 5 prism 丨 8. Due to the different polarization directions of the upper and lower beams, it is affected by the polarization splitting interface in the Kosters prism 18. The light in the light path is almost completely reflected on the interface, and the light beam in the following light path is almost completely transmitted on the interface. The light east through the same row on the liquid crystal panel and the following divided area passes through the Kosters prism After 18, they will be joined together. That is to say, after the beams of the divided areas pass through the Kost; ers prism 1 §, they will become two frames, and each frame includes two different image areas. Here, the three screens are projected from the upper and lower six light sources, and the projection directions of the upper and lower J light sources are different. Therefore, the screens on the two divided areas in the same row will share a projection lens, such as As shown in Figure 3, that is, the three screens are projected onto the biconvex cylindrical lens plate 25 through the three projection lenses 20 '.-The light beam on the divided area of each liquid module is projected by the projection lens To the image formed by the entire lenticular cylindrical lens plate 25, and the opening center of the projection lens is located on the optical axis of the focusing system.

In addition, a conjugate relationship is formed between the observation position of the human eye and the diffusion plate 25 'by the biconvex cylindrical lens on the biconvex cylindrical lens plate 25. The six angles of view correspond to the six half openings η of the projection lens, respectively. Each biconvex cylindrical lens τ has six lines for imaging. Combining the Nth line under all double-product cylindrical lenses will form the Nth picture, so you can see the picture of the νth divided area at the Nth angle of view. Printed by the Employee Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs in the multi-view autostereoscopic display system using split screens of the present invention, the urban connection projects the screen on a biconvex cylindrical lens plate, such a biconvex cylindrical lens In the production of the board, since it is necessary to attach the two cylindrical lens plates to Qiqi, the production accuracy is expected to be extremely high, and it is not easy to manufacture. Please refer to FIG. 6, so in the present invention, another embodiment replaces the aforementioned biconvex cylindrical transflective plate with a beam splitter 22 and two reflective cylindrical lens plates 24 and 26. Similarly, the diffuser plate 24 and 26 are provided on the back of the cylindrical lens-plates M and 26, respectively. Since the reflective cylindrical lens plate has low accuracy requirements, it is easy to manufacture, and is more suitable for mass production. The working principle is the same as the previous one. After the projection lens 20, the picture is first projected to the spectroscopic lens 22, and then is reflected by the reflective material to the reflective cylindrical lens plate Μ%, and then after the spectroscopic Device 22 and projected onto the viewing window 27. 8 paper rulers Lai Caiguan 297 ^ *)
