WIPO Patent Application WO/2020/228581

A1

A pixel circuit (10, 30, 40, 50, 60, 70, 80, 144) and a driving method therefor, and a display apparatus (140). The pixel circuit (10, 30, 40, 50, 60, 70, 80, 144) comprises: a light-emitting component (13, 53, 83) comprising a plurality of light-emitting elements (20, LEDi); a driving sub-circuit (11, 31, 81) electrically connected to the light-emitting component (13, 53, 83) and configured to generate a driving current for driving the light-emitting component (13) to emit light; and a repair sub-circuit (12, 52, 82) electrically connected to the light-emitting component (13, 53, 83) and configured to receive a repair scanning signal (Gate_R, Gate_Ri) and a repair data signal (Data_R, Data_Ri) and to provide, under the control of the repair scanning signal (Gate_R, Gate_Ri) and the repair data signal (Data_R, Data_Ri), the driving current for at least one light-emitting element (20, LEDi), capable of normally emitting light, from among the plurality of light-emitting elements (20, LEDi), so as to cause the light-emitting component (13, 53, 83) to emit light when there is a light-emitting element (20, LEDi), which has a fault, in the plurality of light-emitting elements (20, LEDi).
