Abstract
There are provided a shift register unit and a driving method thereof. The shift register unit includes: an input circuit, whose first terminal receives an input signal of the shift register unit, and second terminal is connected to a pull-up node, the input circuit being configured to output the input signal to the pull-up node; an output circuit, whose first terminal is connected to a clock signal terminal, second terminal is connected to the pull-up node, third terminal is connected to an output terminal of the shift register unit, the output circuit being configured to output a signal of the clock signal terminal to the output terminal under the control of the pull-up node; a pull-up node control circuit, and the pull-up node control circuit being configured to discharge the pull-up node through third power supply voltage terminal under the control of a first power supply voltage terminal.
