摘要：
A method and apparatus of driving a liquid crystal panel to prevent an image distortion and a non-uniform phenomenon in the light transmissivity caused by propagation delay in a scanning wiring of the liquid crystal panel. Data signal voltages are supplied to a signal wiring with a predetermined time interval in accordance with a delay characteristic of a scanning signal in the scanning wiring. Accordingly, even when the scanning signal is delayed in the scanning wiring, the data signal voltages are accurately applied to all liquid crystal cells and hence a picture displayed on the liquid crystal panel is not distorted.
