Abstract: A system for driving a nematic liquid crystal is used to display high definition color images at a high speed in a liquid crystal display device in which the nematic liquid crystal is confined between a common electrode and a segment electrode that are placed between two polarizing plates. The common electrode is supplied with a sequence of selection pulses, and the segment electrode is supplied with a voltage corresponding to image data to be displayed in response to the selection pulses. the segment electrode is further supplied with a voltage different from the voltage corresponding to the image data in intervals where the selection pulses are not applied to the common electrode.

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, comprises means for applying a sequence of selection pulses to the common electrodes; means responsive to the selection pulses to apply to the segment electrodes a voltage corresponding to image data to be displayed; and means for applying to the segment electrodes a voltage different from the voltage corresponding to the image data in intervals where the selection pulses are not applied. The voltage applied to the segment electrodes is controlled such that the mean value of the voltage be a predetermined constant value.
