Claim Text:
1. A pixel circuit comprising a charging sub-circuit, a first driving sub-circuit, a second driving sub-circuit, a first capacitor and a second capacitor, wherein a first terminal of the first capacitor is connected to a first terminal of the first driving sub-circuit and a first terminal of the second driving sub-circuit, and a second terminal of the first capacitor is connected to the charging sub-circuit and a first terminal of the second capacitor; a second terminal of the first driving sub-circuit is connected to a first light emitting device, and a second terminal of the second driving sub-circuit is connected to a second light emitting device, wherein the flow direction of the driving current flowing into the first light emitting device from the first driving sub-circuit is opposite to that of the driving current flowing into the second light emitting device from the second driving sub-circuit; and the charging sub-circuit is used to charge the first capacitor, the second capacitor is used to maintain the voltage at the second terminal of the first capacitor, and when the first capacitor discharges, the first driving sub-circuit drives the first light emitting device to emit light or the second driving sub-circuit drives the second light emitting device to emit light.
