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.

Abstract: A liquid crystal display device structure is provided for testing display signal lines. The display structure improves sensitivity in detecting shorts or opens in data signal lines. In the display, a first detecting line commonly connects odd-numbered data signal lines of a liquid crystal display panel, and a second detecting line commonly connects even-numbered data signal lines of the liquid crystal display panel. First and second electrostatic discharge (ESD) preventing circuits are respectively connected to the odd and even-numbered data signal lines. A first electrode line commonly connects the first ESD preventing circuits and a second electrode line commonly connects the second ESD preventing circuits. Resistances are connected in series between the common electrode lines to increase a detectable critical resistance between the two detecting lines, to thereby improve sensitivity in signal line fault detection.
