  • Patent number: 6771326
    Abstract: A multi-screen laser projection system comprises a laser source that generates a plurality of laser beams, an image display control system, a plurality of modulator arms each including a light modulator; and an optical switch coupled to the image display control system and modulators. A plurality of projection optical systems are respectively arranged to project the modulated light from each modulator onto its associated screen. The optical switch is arranged to receive the plurality of beams from the laser source and switch each of the beams to one of the modulator arms in order to illuminate each modulator with a sequence of colors during each frame. During the course of a frame, each of the colors becomes incident upon the modulator. The projection system disclosed herein can provide a cost-effective, efficient true digital projection display system with high resolution and high brightness.
