Abstract:
1. A method for driving a liquid crystal display device including a gate driver for supplying gate signals to gate lines on a liquid crystal panel and a data driver for supplying data voltage to data lines on the liquid crystal panel, the data driver being composed of a plurality of data driver integrated circuit chips respectively mounted on a plurality of tape carrier packages, the method comprising: generating, by a partial controller, a vertical window control signal which controls an output time period of the gate driver to the gate driver, and providing the vertical window control signal to a frame delayer; receiving, by the frame delayer, the vertical window control signal from the partial controller, and delaying the vertical window control signal by one frame corresponding to one vertical synchronous signal prior to providing the vertical window control signal to the gate driver; providing the vertical window control signal to the gate driver through one among the plurality of tape carrier packages; controlling the gate driver to intercept a part of the gate signals to be supplied to the gate lines; and controlling the data driver to initialize pixels on the liquid crystal panel corresponding to the part of the gate signals with a black color, wherein the vertical window control signal has a vertical window pulse of a low logic for designating an output limit period of the gate signal during a time period of a vertical synchronous signal.
