摘要:
A light-emitting driving circuit includes a driving sub-circuit, a control sub-circuit, a data writing sub-circuit and a compensation sub-circuit. The control sub-circuit is configured to initialize voltages of a first node and a control terminal of the driving sub-circuit in response to a second scan signal. The data writing sub-circuit is configured to write a data signal into a first terminal of the driving sub-circuit in response to a first scan signal. The driving sub-circuit is configured to output, from a second terminal of the driving sub-circuit, the data signal and a compensation signal. The compensation sub-circuit is configured to transmit the data signal and the compensation signal to the first node in response to the first scan signal, and adjust the voltage of the control terminal according to the data signal, the compensation signal, the initialized voltages of the first node and the control terminal.
