Development of the baseline technology for liquid-crystal-on-silicon microdisplay and advanced display materials and devices

Abstract

Building display on silicon has been explored for its advantages of low power, high resolution and low cost of manufacturing. Using silicon allows complex and high-density circuits to be build on the same substrate as the display itself, eliminating off-chip interconnects to realize a Display-on-Chip (DOC). In addition, dense layout rules of CMOS processes allow pixels to be placed very close together. Regardless of reflective (liquid-crystal-on-silicon) or emissive (organic light-emitting device), the aperture ratio typically of greater than 90% is attainable for most CMOS processes.
