Abstract

We have newly developed a few kinds of new auto-stereoscopic 3D displays adopting a ray-regenerating method. The method is invented basically at Osaka University in 1997. We adopted this method with LCD. The display has a very simple construction. It consists of LC panel with a very large number of pixels and many small light sources positioned behind the LC panel. We have examined the following new technologies: 1) Optimum design of the optical system. 2) Suitable construction in order to realize very large number of pixels. 3) Highly bright back-light system with optical fiber array to compensate the low lighting efficiency. The 3D displays having wide viewing area and being visible for plural viewers were realized. But the cross-talk images appeared more than we expected. By changing the construction of this system to reduce the diffusing factors of generated rays, the cross-talk images are reduced dramatically. Within the limitation of the pixel numbers of LCD, it is desirable to increase the pinhole numbers to realize the realistic 3D image. This research formed a link in the chain of the national project by NEDO (New Energy and Industrial Technology Development Organization) in Japan.
