Abstract :
The ability to display high-resolution images is a requisite of widespread use of high-bandwidth portable information devices. Liquid-crystal-on-silicon (LCOS) technology enables same-die integration of control circuitry and display for substantial overall system power reduction. This 160/spl times/120 LCOS microdisplay uses 25 /spl mu/m pixels based on a 0.8 /spl mu/m 3-metal silicon backplane. The display integrates 6b sampled-ramp digital-to-analog converter (DAC) column drivers that consume 7.25 mW (worst case) at 4 MHz and 5 V.
