BRIGHTER LIGHT ENGINE ARCHITECTURE FOR A LIQUID CRYSTAL DISPLAY PROJECTION SYSTEM

摘要

A liquid crystal display projection system, comprising: a source of a repetitive three color sequence of light (13); first and second imagers (20, 22) responsive to the same drive signal; at least a first polarizing beam splitter (14) 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 (26) for removing P polarized light directed to said first imager; a second filter (24) for removing P polarized light reflected from said second imager, and, said at least first polarizing beam splitter combining said light reflected from said first imager and said light filtered by said second filter as an output.
