Shift register and driving method therefor, gate driver circuit, and display device

A shift register, comprising a pull-up node, an output control sub-circuit, a first energy storage sub-circuit and an output sub-circuit, wherein

• the output control sub-circuit is coupled to the pull-up node, a first clock signal terminal and the first energy storage sub-circuit;
• and the output control sub-circuit is configured to transmit a first clock signal received at the first clock signal terminal to the first energy storage sub-circuit under control of a voltage of the pull-up node;
• the first energy storage sub-circuit is coupled to the pull-up node and the output control sub-circuit;
• and the first energy storage sub-circuit is configured to store the voltage of the pull-up node, and boost the voltage of the pull-up node under action of the first clock signal;
• and
• the output sub-circuit is coupled to the pull-up node and a signal output terminal;
• and the output sub-circuit is configured to transmit the boosted voltage of the pull-up node to the signal output terminal under the control of the voltage of the pull-up node.
