摘要： A method for driving a liquid crystal display adjusts the falling edges of the gate driving signals for reducing image flicker. A first gate driving signal falls from a high level to a first level at the signal falling edge. A second gate driving signal falls from the high level to a second level at the signal falling edge. When the parasitic capacitance of a first pixel is larger than that of a second pixel, the first level is lower than the second level; when the parasitic capacitance of the first pixel is substantially the same as that of the second pixel, the first level is the same as the second level; when the parasitic capacitance of the first pixel is smaller than that of the second pixel, the first level is higher than the second level.
