Abstract

A 64×32 liquid-crystal-on-silicon (LCOS) microdisplay with a frame buffer pixel architecture is described. The advantage of frame buffer pixel circuits is an increase in brightness and image contrast ratio. The increase in brightness is attributed to maximizing the overall image viewing time, allowing an image to be displayed at full contrast while the next image is loaded onto the pixels. The LCOS microdisplay employs a fast-switching optically compensated birefringence mode that operates at a 720-Hz frame frequency with a potentially high contrast ratio.
