New auto-stereoscopic video image display screens

Describes the construction and performance of video screens for presenting 3-D displays: a "tracked" flat 15" or 20" liquid crystal screen, and a 42" plasma screen using lens raster technology. Also referred to is a projection system with a double strip structure (125 cm diameter) for highest resolution. Details are given of a 3-D back projection system, a 14" flat screen, and a 3-D LCD monitor 15" diameter, using 1536 lenses of 200 microns size. Lens raster and strip raster methods are explained, and diagrams of tracking systems are presented. Display characteristic are tabulated, and images achieved are shown.
