Abstract
The present invention providing a gate driver used in display panel, wherein comprises: a chamfering module is configured to receive gate turn-on voltage signals and square wave controlling signals, and chamfers the gate turn-on voltage signals in accordance with the square wave controlling signals to generate and output chamfered gate turn-on voltage signals; and a level shifting module is configured to receive the chamfered gate turn-on voltage signals, inputs voltage signals and gate cut-off voltage signals, and outputs the chamfered gate turn-on voltage signals or the gate cut-off voltage signals in accordance with a voltage value of the input voltage signal. By integrating a chamfering module and a digital adjustable resistance module into a gate driver, it is not necessary to provide a chamfering circuit on a CB of display panel, so as the CB can be miniaturized.
