ABSTRACT:
A three dimensional large screen liquid crystal projection display utilizes wo liquid crystal light valves in tandem to produce polarization-type stereoscopic images in a large screen display format. Each light valve, driven separately by video input derived either from live scenes or computer generated data, presents one view of a stereoscopic image pair. Using one projection lamp, one projection lens, and a polarizing beamsplitter cube, the two images are optically combined and projected simultaneously onto a non-depolarizing screen. The particular optical geometry used results in orthogonal linear polarizations for the two images, so they can be viewed stereoscopically using polaroid glasses with appropriately oriented polarizing axes.
