摘要

提出了一种超低功耗驱动系统，用于驱动有源矩阵液晶显示器的柱线。演示系统是一个160/spl倍/120像素的硅基液晶(LCOS)微显示器。实验室测量表明，相对于CV/sub / dd/V/sub - out/，节能50%至65%，这是传统驱动器消耗能量的下限。当在25 MHz像素频率、60 Hz刷新率和5 V工作电压下显示黑白格子图像时，该显示器的列驱动器耗散仅为10 /spl mu/W。

A low-power adiabatic driver system for AMLCDs

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.
