Abstract
A liquid crystal display having reduced power consumption. The liquid crystal display includes a liquid crystal display panel having a plurality of pixels and a plurality of pixel memories. A pixel voltage is stored in a pixel memory in an on screen display (OSD) region of the liquid crystal display panel for displaying a still image for a long period of time and driving a liquid crystal cell by the stored pixel voltage. Also, the power consumption of the liquid crystal display can be reduced by using a NAND gate or a NOR gate as a circuit element for alternating a voltage between low level and high level so as to store a pixel voltage in a pixel memory of the liquid crystal display.
