Abstract:
A system for driving a nematic liquid crystal in a liquid crystal display device which includes a nematic liquid crystal, a plurality of common electrodes and a plurality of segment electrodes confining the nematic liquid crystal therebetween, and a pair of polarizing plates sandwiching the common electrodes and the segment electrodes confining the nematic liquid crystal, comprising:means for applying a sequence of selection pulses to said common electrodes; means for applying a voltage corresponding to image data to be displayed to said segment electrodes in intervals where said selection pulses are applied; and means for applying a second voltage related to said voltage corresponding to image data in intervals where said selection pulses are not applied, said second voltage being determined such that the mean value of effective values of applied voltages is a predetermined constant value for each frame and the same mean value for each subsequent frame, thereby removing cross talk.
