US 7,411,722 B2 · Display system incorporating bilinear electromechanical grating device

Abstract

A line scanned display system includes at least three different colors of illumination provided by one or more light sources, and at least one directional illumination optical system for directing the three different colors of illumination. Also in the system is a bilinear array, having two linear arrays of light modulating devices, situated on a common substrate for receiving and modulating two different colors of illumination at any one time that are obtained from the three different colors of illumination. Finally, a lens for creating line images of the two linear arrays on a screen and a scanning mirror for scanning the line images across the screen to form an area image complete the system.
