Driving method of liquid crystal display device

摘要

To provide a driving method of a liquid crystal display device which method is superior in image quality and reliability and can reduce the power consumption even if the gate line load is increased as a result of increased size of a display screen, improved resolution, and an increased aperture ratio in an active matrix liquid crystal display device in which switching elements such as thin-film transistors (TFTs) and pixel electrodes are arranged in matrix form. In a first frame, occurrence of a DC component due to gate delaying is prevented by outputting a compensation voltage at the same timing as a gate-off timing so as to attain a condition of DELTA V = 0. In a second frame, a second compensation voltage is output so that DELTA V becomes a target value. Since the second output is not influenced by the gate delaying, DELTA V can be made large. <IMAGE>
