ABSTRACT:
A method and circuit for driving LCD are provided. Because the conventional Vcom inversion drive method cannot be applied in a self-aligned process, the power consumption cannot be reduced when the size of the transistor decreases. The method and circuit provided uses two different AC signals to provide different reference voltages for the storage capacitor and the liquid crystal capacitor in a pixel respectively. Therefore, it can be applied to the self-aligned process to reduce the power consumption.
