  • Single light valve color projection system
    Patent number: 5822025
    Abstract: A high performance single light valve color projection system that enables sequential display of color, and an addressing process for this system. Several rotating glass plates are sequentially inserted between the light valve and the objective. These glass plates create a spatial offset of the image of light valve pixels three times per frame on the projection screen. The sets of plates are rotated by a motor with an axis parallel to the optical axis of the motor, and intersect the image beam at each image frame.
