Classification: CPC G | IPC G

Claim 1:
2. The pixel driving circuit according to claim 1, wherein
the current leakage suppression sub-circuit is coupled to the second node, so that the current leakage suppression sub-circuit is coupled to the energy storage sub-circuit through the second node;
the current leakage suppression sub-circuit is further coupled to a fourth node and the light-emitting timing signal terminal;
the compensation sub-circuit is coupled to the fourth node, so that the compensation sub-circuit is coupled to the second node through the fourth node and the current leakage suppression sub-circuit;
the reset sub-circuit is coupled to the fourth node, so that the reset sub-circuit is coupled to the second node through the fourth node and the current leakage suppression sub-circuit;
the current leakage suppression sub-circuit is configured to be turned off under control of the light-emitting timing signal to suppress the current leakage of the energy storage sub-circuit; and is further configured to: transmit the initial signal from the reset sub-circuit to the second node in response to the light-emitting timing signal; be turned on under control of the light-emitting timing signal; and cause the driving sub-circuit to be in the self-saturation state due to a combined action of the current leakage suppression sub-circuit and the compensation sub-circuit that is in an on state.
