ABSTRACT:
A liquid-crystal display includes common electrodes and segment electrodes and responds to signals applied to the common electrodes and the segment electrodes, to display an image. A display controller responds to a received signal to generate a gradation indicating signal indicating a gradation of each of the pixels of the display. A common driver simultaneously selects k adjacent common electrodes for scan, compensates the gradation indicating signal, and supplies the compensated signal to the segment electrodes in order to decrease the difference between the gradation of each pixel indicated by the gradation indicating signal and an actually displayed gradation which results from the simultaneous selection of the common electrodes.
