Abstract

The embodiments of the present disclosure relate to a shift registers unit and a driving method thereof, and a gate driving device. The shift register unit includes a first and second input circuit, a pull-down control circuit, an output circuit, a pull-down circuit, and a control circuit. The first input circuit provides a first control signal to a pull-up node. The second input circuit provides a second control signal to the pull-up node. The pull-down control circuit provides the voltage of a first voltage terminal to a pull-down node, or controls the voltage of the pull-down node. The output circuit provides a second clock signal to a signal output terminal. The pull-down circuit provides the voltage of the first voltage terminal to the pull-up node and the signal output terminal. The control circuit provides the first input signal to the pull-up node.
