Abstract

A shift register includes a first input sub-circuit, a pull-up control sub-circuit, and a pull-down control sub-circuit. The first input sub-circuit is configured to transmit a voltage from the first signal terminal to the first node under control of the first voltage terminal. The pull-up control sub-circuit is configured to be in a turn-on or turn-off state under control of the first node. The pull-down control sub-circuit is configured to transmit a voltage from the third voltage terminal to the pull-down node under control of the first node, transmit the voltage from the third voltage terminal to the pull-down node under control of the signal output terminal, and transmit a voltage from the first clock signal terminal to the pull-down node under control of the first clock signal terminal.
