Abstract
A color LCoS microdisplay device, consisting of a CMOS silicon backplane, a metal reflector array, a lower LC alignment layer, an LC layer, an upper LC alignment layer, a transparent conductive layer, and a cover glass plate, with a micro-dichroic-filter array between the said upper LC alignment layer and the said cover glass plate. Each pixel of the said micro-dichroic-filter array corresponds with a pixel of the said metal reflector array. And the said pixels of the said metal reflector array also serve as electrodes, which can be activated individually with a charge of DC voltage or pulse. Thus a single panel projection color display system is achieved.
