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.

摘要： An exemplary gate output control method includes the following steps: providing a gate control signal; using an angling control signal to angling modulate the gate control signal so as to generate a modulated gate control signal; and supplying the modulated gate control signal to a first integrated gate driver circuit and a second integrated gate driver circuit, to sequentially control the gate outputs of the first integrated gate driver circuit and the second integrated gate driver circuit. A duty ratio used by the angling control signal at the time of modulating the gate control signal to generate the modulated gate control signal for the first integrated gate driver circuit is different from another duty ratio used by the angling control signal at the time of modulating the gate control signal to generate the modulated gate control signal for the second integrated gate driver circuit.
