摘要:
A method of driving a matrix type liquid crystal display device which compensates for the distortion of scanning signal and data waveforms caused by resistance and capacitance of the display device electrodes. In one embodiment of this method the timing of the scanning signal is advanced with respect to the timing of the data switching signal by a time determined by the resistor-capacitor time constant of the electrodes and display elements. In another embodiment of this method the switching timing of the scanning signal is delayed with respect to the leading edge of the data signal and the switching timing of the scanning signal is advanced with respect to the trailing edge of the data signal. The delay of the leading edge and the advance of the trailing edge are determined by the resistor-capacitor time constant of the electrode and display elements and the capacitance of the display element, respectively.
