Gate output control method and corresponding gate pulse modulator

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.
