ABSTRACT:
A method for driving a thin film transistor-liquid crystal display using line inversion includes the steps of applying a gate driving pulse to a gate of the thin film transistor; applying a data signal, varied between low and high data signal levels, to one of a drain and a source of the thin film transistor, the other of the drain and the source connected to a first terminal of a pixel of the liquid crystal display; and applying a common voltage, varied between low and high common voltage levels, to a second terminal of the pixel, the level of the common voltage being inverted with respect to the level of the data signal to drive the pixel in varying directions corresponding to a positive field and a negative field, and the gate driving pulse for a gate low level being varied between the positive field and the negative field.
