Classification: CPC G  H | IPC G

Claim 4:
5. The display apparatus according to claim 1, wherein:
the node control sub-circuit comprises a write sub-circuit; a drive sub-circuit; a compensation sub-circuit; and an energy storage sub-circuit;
the write sub-circuit is connected with the scan signal line, the second reset line, the data signal line and the second node, respectively, and configured to provide a signal of the data signal line for the second node or discharge to the second node under control of the scan signal line and the second reset line;
the drive sub-circuit is connected with the first node, the second node, and the third node, respectively, and configured to provide a signal of the second node for the third node under control of the first node;
the compensation sub-circuit is connected with the first node, the second reset line and the third node, respectively, and configured to provide a potential of the third node for the first node under control of the second reset line to compensate for the first node until the voltage of the first node satisfies a threshold condition; and
the energy storage sub-circuit is connected with the first power supply line and the first node, respectively, and configured to store a voltage difference between the first power supply line and the first node.
