ABSTRACT:
A switchable color filter comprising a pair of twisted nematic liquid crystal devices (126 and 128) and a light polarizing system (108) which includes three color selective polarizing filters (102, 104, and 106) is incorporated as an optical subassembly in a field sequential color display system (100) to provide output states of white light and light of three different colors to form an image in full color and high brightness with strong color contrast.
