摘要
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 160x120 pixel liquid-crystal-on-silicon (LCOS) microdisplay. Laboratory measurements show an energy savings of 50% to 65% relative to CVddVout, which is the lower limit for the energy consumed by a conventional driver. The column drivers of this display dissipate only 10 mu W when displaying a checkered, black and white image at a 25MHz pixel frequency, 60Hz refresh rate, and 5V operating voltage.
