Abstract
A pixel compensation circuit and a driving method thereof are provided. The pixel compensation circuit includes a resetting unit, a write-in unit, a light-emitting unit, a storage capacitor and a driving transistor. 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. 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.
