摘要： A pixel circuit includes a data writing and compensation sub-circuit, a driving sub-circuit, and a light-emitting control sub-circuit. The data writing and compensation sub-circuit is configured to transmit a data signal from a data voltage terminal to the driving sub-circuit under control of a first control signal terminal, and to compensate a threshold voltage of the driving sub-circuit under the control of the first control signal terminal. The light-emitting control sub-circuit is configured to transmit a first voltage signal from a first voltage terminal to the driving sub-circuit and the data writing and compensation sub-circuit under control of a second control signal terminal, and to transmit a second voltage signal from the second voltage terminal to the driving sub-circuit under the control of the second control signal terminal. The driving sub-circuit is configured to transmit a signal output from the light-emitting control sub-circuit to a light-emitting sub-circuit.

摘要： A shift register includes a pull-up node, an output control sub-circuit, a first energy storage sub-circuit and an output sub-circuit. 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 is configured to transmit a first clock signal 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 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. The output sub-circuit is coupled to the pull-up node and a signal output terminal, and 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.
