Abstract

Stereoscopic liquid crystal displays are described that permit the observation of a stereo pair by several persons simultaneously without the use of special glasses. One of the systems is composed of a right eye system, a left eye system, and a special infrared illuminating system. In the right eye system, a transparent type color liquid crystal plate is used with a special back light unit. The back light unit consists of a monochrome 2D display and a large format convex lens. The unit distributes the light to the viewers' right eye only. The right eye system is combined with a left eye system by a half mirror in order to function as a time-parallel stereoscopic system. Another system consists of a large format convex lens, a polarizer and liquid crystal plate, and a color 2D display. The color 2D display superposes left eye and right eye perspectives on the display as polarized images that are polarized 90 degrees to each other. The polarized images are distributed to the viewers' correct eyes because the polarizer and liquid crystal plate occludes the incorrect eye. These systems are applicable not only to stereoscopic receivers for domestic use but also medical devices for stereoscopic purposes.
