Classification: CPC G | IPC G

Claim 0:
1. A pixel compensation circuit, comprising a resetting unit, a write-in unit, a light-emitting unit, a storage capacitor and a driving transistor, wherein
the resetting unit is configured to receive a resetting signal and release electric energy on the storage capacitor and an electroluminescence element;
the write-in unit is configured to receive a gate driving signal and write display data into a holding node coupled to the storage capacitor;
the light-emitting unit is configured to receive a light-emitting signal and turn on the driving transistor to enable the electroluminescence element to emit light; and
a compensation unit is added between the holding node and a high potential end and configured to generate a reverse current for compensating a leakage current of the resetting unit;
the compensation unit comprises a first compensation transistor and a second compensation transistor, a gate electrode of the first compensation transistor is configured to receive the light-emitting signal, a first electrode of the first compensation transistor is directly coupled to the holding node, and a second electrode of the first compensation transistor is directly coupled to a first electrode of the second compensation transistor; and
a gate electrode and a second electrode of the second compensation transistor are configured to receive the gate driving signal.
