Abstract

The architecture and circuit design of a single panel liquid crystal on silicon (LCoS) backplane IC that includes 1408 /spl times/ 844 pixels and drives 8 color sub-frames/one video frame is described. There are 1408 DACs to improve picture uniformity and one analog frame buffer to reduce video bandwidth. Each pixel has 256 gray levels and 12 /spl mu/m pitch. The IC, fabricated in UMC 0.35 /spl mu/m 5M LCoS technology, is used successfully in projection applications.
