Abstract
A shift register includes a pull-up control circuit, a pull-up circuit, a pull-down control circuit, a pull-down circuit, and a reset circuit. The pull-down circuit is connected to the pull-down node, the pull-up node, a second control terminal, a first voltage terminal, and a signal output terminal, and is configured to pull down potentials of the pull-up node and the signal output terminal to a potential of the first voltage terminal under the control of the pull-down node; moreover, the pull-down circuit is further configured to pull down potentials of the pull-up node and the signal output terminal to a potential of the first voltage terminal under the control of a signal from the second control terminal.
