Development of an 8-bit VGA LCOS microdisplay with FSC modes using a low-cost process

— A VGA-resolution LCOS microdisplay operated in the field-sequential color (FSC) mode was fabricated using a low-cost process. An 8-bit digital data driver with digital-to-analog converters, which can realize a 256-level gray scale and gamma compensation, has been integrated into a color microdisplay. A top-to-bottom approach to the design of an FSC LCOS microdisplay is described. The design of the silicon-backplane circuits is outlined in detail. Finally, a prototype of this display and its imaging performance are discussed.
