Gate driver circuit of display panel, driving method therefor and display device

A driving method for a gate driver circuit of a display panel, comprising steps of:

• receiving a clock signal through a charging circuit, and outputting an initial gate scanning signal in a scanning time;
• controlling a pull-down circuit to pull down a potential of an output terminal of the charging circuit to a low level in a non-scanning time;
• and
• connecting to an enable signal and controlling the output of the gate scanning signal according to the enable signal by an output control circuit;
• wherein when a current-stage initial gate scanning signal is switched from a high level to a low level, the enable signal is a rising edge signal and controls the output control circuit to output a preset low level.

A display device, comprising a display panel and a gate driver circuit of the display panel;

• the gate driver circuit comprises a multi-stage cascaded shift register, wherein an any-stage shift register comprises:
• a charging circuit, receiving a clock signal and outputting an initial gate scanning signal in a scanning time;
• a pull-down circuit, controlling to pull down a potential of an output terminal of the charging circuit to a low level in a non-scanning time;
• and
• an output control circuit, electrically coupled to the output terminal of the charging circuit to receive an initial gate scanning signal, connected to an enable signal and controlling the output of the gate scanning signal according to the enable signal;
• wherein when a current-stage initial gate scanning signal is switched from a high level to a low level, the enable signal is a rising edge signal and controls the output control circuit to output a preset low level.
