Abstract: A method of driving a liquid crystal display that is adaptive for improving a picture quality is provided. In the method, a clock signal is applied to a gate driver. First to third gate output enable signals are applied to the gate driver. A scanning pulse is applied to two gate lines during one period of the clock signal. Accordingly, a desired picture is displayed over a black picture, so that it becomes possible to prevent a motion blur phenomenon. Also, a capacitance value of the liquid crystal cell is fixed, so that a voltage drop amount of the data pulse can be predicted and determined, and the voltage drop amount of the data pulse can be compensated.
