Abstract
The present disclosure provides a shift register, a gate driving circuit, a display panel, and a driving method thereof. The shift register includes: an input circuit; an output circuit; a first control circuit configured to provide a potential of a first control signal terminal to a pull-down node, and provide a potential of a reference signal terminal to the pull-down node according to the potential of the pull-up node; and a second control circuit connected to the pull-down node, a second control signal terminal, the output signal terminal, and the reference signal terminal, wherein the second control circuit is configured to pull down a potential of the output signal terminal during a display phase under the control of a potential of the pull-down node and a potential of the second control signal terminal, and pull up the potential of the output signal terminal in a power-off phase.
