Paper Abstract

A display system requiring no special glasses is a useful technology for 3D images. The rear projection lenticular 3D display system using a projector has superior characteristics, such as having a large screen with wide field of view. However, a conventional system has disadvantages such that the observer perceives reverse images when he views a left image by his right eye and vice versa. To solve this problem, this paper describes the technique of making invisible area using a polarized slit barrier. Using this technique, we propose the 3D display using polarized slit for elimination of pseudoscopic viewing area to solve the pseudoscopic image problem. Moreover, we describe a development of new system for displaying 4-views images. This is the stereoscopic display with the 4-views using the combination of a parallax polarized slit and cylindrical lenses. It is possible that the image resolution of each view is reduced both horizontally and vertically using this combination. This 4-views stereoscopic 3D displays can avoid the horizontal resolution problem of conventional system.
