摘要:
A pixel driving circuit includes a reset sub-circuit, an input sub-circuit, a driving sub-circuit, a compensation sub-circuit and an voltage control sub-circuit. The reset sub-circuit is configured to be turned on in response to a control signal, and transmit a reference voltage to a first node to reset a voltage of the first node. The input sub-circuit is configured to transmit a data signal to a second node in response to a gate scan signal. The driving sub-circuit is configured to be turned on or off in response to a voltage of the first node; and to write the data signal and a compensation signal into a third node. The compensation sub-circuit is configured to transmit the data signal and the compensation signal to a fourth node in response to the gate scan signal. The voltage control sub-circuit is configured to control the voltage of the first node according to a voltage of the fourth node. The driving sub-circuit is further configured to output a driving signal according to the voltage of the first node.
