Abstract
The present application discloses a gate driver circuit of a display panel, a driving method therefor and a display circuit. The gate driver circuit of a display panel includes a multi-stage cascaded shift register, where an any-stage shift register includes: a charging circuit, a pull-down circuit for 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 for receiving an initial gate scanning signal; the output control circuit is connected to an enable signal and controls the output of the gate scanning signal according to the enable signal.
