Abstract
A shift register includes an output sub-circuit and a compensation sub-circuit. The output sub-circuit is coupled to a pull-up node, a clock signal terminal and a signal output terminal. The compensation sub-circuit is coupled to the pull-up node, the clock signal terminal and the signal output terminal. The output sub-circuit is configured to transmit a voltage of the clock signal terminal to the signal output terminal under control of a voltage of the pull-up node, The compensation sub-circuit is configured to transmit a voltage of the signal output terminal to the pull-up node under control of the voltage of the pull-up node and the voltage of the clock signal terminal.
