Abstract

On-the-wall stereoscopic liquid crystal displays are described that permits the observation of a stereo pair by several persons simultaneously without the use of special glasses. One of the on- the-wall systems is composed of a high refresh rate transparent type color liquid crystal plate with a special back light unit and an infrared illuminating and the image taking system. The back light unit consists of a monochrome 2D display and a convex lens array. The unit distributes the light to the viewers' correct eyes. The system is a time-interface stereoscopic system. Another system consists of a transparent type color liquid crystal plate which polarizer must be micropolarizer with a special back light unit and an infrared illuminating and the image tracking system. The back light unit consists of a monochrome 2D liquid crystal display eliminated its polarizing analyzer and a convex lens array. The unit distributes the light to the viewers' correct eyes. The system is a spatial-multiplexing stereoscopic system. These systems were able to enlarge the image size and to shorten the thickness of the display.
