Abstract
A shift register, a gate driving circuit, a display panel and a driving method. The shift register includes: an input circuit, connected with a pull-up node and an input signal terminal respectively; a reset circuit, connected with the pull-up node, a reset signal terminal and a first power terminal respectively to receive a first power voltage; an output circuit, connected with the pull-up node, a clock signal terminal and an output terminal respectively; and an output pull-down circuit, connected with the output terminal and configured to write a second power voltage to the output terminal, where the first power voltage is different from the second power voltage.
