Claim 4:
5. A method for driving the pixel compensation circuit according to claim 1, comprising:
in the case that the first compensation transistor is turned off and the compensation unit does not work, enabling a first resetting transistor in the resetting unit to be turned on under the control of the resetting signal so as to enable a second end of the storage capacitor to be electrically coupled to a second power source and release electric energy on the storage capacitor, and enabling a second resetting transistor in the resetting unit to be turned on so as to enable an anode of the electroluminescence element to be electrically coupled to the second power source and release electric energy on the electroluminescence element;
in the case that the first compensation transistor is turned off and the compensation unit does not work, enabling a first write-in transistor and a second write-in transistor in the write-in unit to be turned on under the control of the gate driving signal, so as to enable display data to charge the storage capacitor through the first write-in transistor, the driving transistor and the second write-in transistor and write the display data into the holding node; and
in the case that the first compensation transistor is turned on, the second compensation transistor is turned off, a potential at a second electrode of the second compensation transistor is higher than a potential at the holding node, and a compensation leakage current flowing to the holding node is generated on the second compensation transistor, enabling a first light-emitting transistor and a second light-emitting transistor in the light-emitting unit to be turned on under the control of the light-emitting signal, and enabling the driving transistor to be turned on, so as to drive the electroluminescence element to emit light.
