A device for controlling the gate drive voltage in the liquid crystal display is provided in the invention. The device for controlling the gate drive voltage in the liquid crystal display according to the invention includes a turn-on voltage output terminal and a turn-off voltage output terminal for outputting a turn-on voltage and a turn-off voltage to a gate drive circuit, respectively, and a control circuit. The control circuit is coupled with the turn-on voltage output terminal and exerts an influence on the turn-on voltage so that the turn-on voltage has a ripple similar to that of the turn-off voltage. |
