Abstract:
A gate driving unit, a gate driving method, a gate driving circuit, a display panel and a display device are provided. The gate driving unit includes a start terminal, a first gate driving signal output terminal, a second gate driving signal output terminal, a pull-up control node control circuit, a pull-up node control circuit, configured to control a potential of a first pull-up node and a potential of a second pull-up node based on the potential of the pull-up control node, a first gate driving signal output circuit, a second gate driving signal output circuit, and a pull-down node control circuit, configured to control and maintain the potential of the pull-down node under the control of a third clock signal and a fourth clock signal, and control to reset the potential of the pull-down node under the control of the potential of the pull-up control node.
