Abstract :
We present an ultra low-power driver system for driving the column lines of an active matrix liquid-crystal display. The demonstration system is a 160/spl times/120 pixel liquid-crystal-on-silicon (LCOS) microdisplay. Laboratory measurements show an energy saving of 50% to 65% relative to CV/sub dd/V/sub out/, which is the lower limit for the energy consumed by a conventional driver. The column drivers of this display dissipate only 10 /spl mu/W when displaying a checkered, black and white image at a 25 MHz pixel frequency, 60 Hz refresh rate, and 5 V operating voltage.
