ABSTRACT:
A method for driving a liquid crystal display device including a plurality of row electrodes intersecting a plurality of column electrodes, a scanning voltage applied to each of the row electrodes, and a signal voltage applied to each of the column electrodes, the method comprising the steps of: a) determining, for each of the column electrodes, correction data for correcting the signal voltage based on an increment or a decrement of an effective voltage value between each of row electrodes and each of the column electrodes; and b) applying a correction voltage for correcting the signal voltage to each of the column electrodes in accordance with the correction data. An increment or decrement of the effective voltage value may be due to i) at least either a blunt waveform or induced distortion of the signal voltage or ii) at least either a blunt waveform or induced distortion of the scanning voltage, or iii) both.
