Electro-optical device system and method of driving an electro-optical device

摘要

An electro-optical device system and a method of driving a liquid crystal display panel thereof capable of constructing clear visual images with low power consumption are described. In the display panel, a plurality of conductive pads are opposed to a back electrode with a liquid crystal layer inbetween. Control signals are supplied to the conductive pads through complementary transistors comprising a p-channel field effect transistor and an n-channel field effect transistor connected between VDD and VSS lines of a control circuit. The information being displayed is simultaneously stored in a first memory. Information desired to be displayed is stored in a second memory and compared with the content of the first memory to produce exclusive ORs thereof. The display panel is driven only when and where the information desired to be displayed is dissimilar to the information being displayed.
