Abstract

A shift register circuit includes a pull-up control sub-circuit, a pull-up sub-circuit and a shutdown auxiliary sub-circuit. The pull-up control sub-circuit is configured to transmit a voltage from the signal input terminal to the pull-up node under the control of the voltage from the signal input terminal. The shut-down auxiliary sub-circuit is configured to pull down a voltage of the pull-up node to a voltage of the discharge voltage terminal under the control of a voltage from the pull-up node. The pull-up sub-circuit is configured to transmit a voltage from the clock signal terminal to the first signal output terminal under the control of a voltage from the pull-up node. The first signal output terminal is configured to be connected to a gate line.
