Abstract: A method for operating a liquid crystal display having a panel with a back light includes applying a first gate signal starting a real data period followed by a second gate signal starting a black data period sequentially to gate lines of the panel, applying actual picture data signals to data lines of the panel during the real data period and reset data signals to the data lines of the panel during the black data period to drive cells of the panel during a frame along a gate line and controlling a ratio of the real data period to the black data period for a subsequent frame.

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 and a method for fabricating a liquid crystal display device wherein two domains are provided within each pixel cell so as to prevent flicker and to widen a viewing angle. In the liquid crystal display device, a common electrode is formed on a first substrate in such a manner to be divided into at least two electrodes. An alignment film is coated on the first substrate provided with the common electrode and a second substrate. A ferroelectric liquid crystal layer is injected between the first substrate and the second substrate to form at least two domains having a liquid crystal alignment state opposed to each other on a basis of a dividing line of the common electrode.
