摘要： A liquid crystal display includes a gate driver, a control circuit and a charge-sharing circuit. The control circuit provides a charge-sharing signal according to the parasitic capacitances at a first output end and a second output end in the gate driver. The charge-sharing circuit generates a third clock signal and a fourth clock signal by performing charge-sharing on a first clock signal and a second clock signal according to the charge-sharing signal. The third clock signal includes a signal falling edge which descends from a high level to a first level, and the fourth clock signal includes a signal falling edge which descends from the high level to a second level. The gate driver outputs a first gate driving signal and a second gate driving signal respectively at the first and the second output end according the third or the fourth clock signal.

摘要： A gate output control method is adapted into a flat display having a plurality of gate drive integrated circuits. The method comprises: providing a gate control signal; providing a oblique control signal to oblique modulate the gate control signal for generating a gate control signal with oblique; modulating the gate control signal with oblique to obtain a modulated gate control signal; and outputting the modulated gate control signal to the gate drive integrated circuits. A falling edge of the modulated gate control signal comprises a oblique-varying period and a vertical-varying period. In the oblique-varying period, the modulated gate control signal firstly changes to a predetermined voltage in a first slope, and then changes in a second slope until the vertical-varying period. In the vertical-varying period, the modulated gate control signal changes vertically or nearly vertically.
