Abstract:
The embodiments of the present disclosure provide a pixel driving circuit of driving a light emitting element to emit light. The pixel driving circuit comprises: a driving sub-circuit, configured to generate a current for making the light emitting element emit light; a light emitting control sub-circuit, electrically coupled to the driving sub-circuit and a first terminal of the light emitting element; a driving control sub-circuit, electrically coupled to the driving sub-circuit, wherein the driving control sub-circuit is configured to provide the data signal to the driving sub-circuit; a resetting sub-circuit, configured to reset the first node and the first terminal of the light emitting element; and a compensation sub-circuit, electrically coupled to the first node, wherein the compensation sub-circuit is configured to receive a compensation control signal, and compensate a voltage of the first node under a control of the compensation control signal.
