Classification: CPC G | IPC G

Claim 6:
7. The pixel driving circuit according to claim 1, wherein
the current leakage suppression sub-circuit is coupled to the first node, so that the current leakage suppression sub-circuit is coupled to the energy storage sub-circuit through the first node;
the reset sub-circuit and the compensation sub-circuit are both directly coupled to the second node;
the current leakage suppression sub-circuit, the compensation sub-circuit and the reset sub-circuit are further coupled to a fifth node;
the current leakage suppression sub-circuit is configured to: be charged due to actions of voltages of the first node and the fifth node; couple, according to the voltage of the first node, the voltage of the fifth node to keep the voltage of the fifth node equal to the voltage of the second node; and maintain a coupled voltage of the fifth node to suppress an current leakage of the second node.
