ABSTRACT:
Power consumption in a liquid crystal display driver is reduced without degrading display quality of a liquid crystal display. Supply of unnecessary oscillation voltage to the liquid crystal display is stopped by turning off all analog switches AS.sub.0 -AS.sub.7 under the control of a signal TI at the moment when voltage applied to the liquid crystal display reaches a desired DC voltage corresponding to display data D.sub.0 -D.sub.2.
