ABSTRACT:
A liquid crystal display projection system for pictures that can be viewed stereoscopically, comprising: a source of a repetitive three color sequence of light; first and second imagers responsive to respective drive signals representative of the same picture from different angles of view; at least a first polarizing beam splitter for separating said repetitive three-color sequence of light into a P polarized three color sequence of light and an S polarized three color sequence of light, said S polarized three color sequence of light illuminating said first imager and said P polarized three color sequence of light illuminating said second imager; a first filter for removing P polarized light directed to said first imager; and, a second filter for removing P polarized light reflected from said second imager, wherein said light reflected from said first imager and said light filtered by said second filter form a stereoscopic image when viewed through respective P and S polarizing lenses.
