Claim Text:
1. A pixel circuit comprising a charging sub-circuit, a capacitor, a first driving sub-circuit and a second driving sub-circuit different from the first driving sub-circuit, wherein a first terminal of the 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 capacitor is connected to the charging sub-circuit, wherein the first terminal of the capacitor is different from the second terminal of the capacitor; a second terminal of the first driving sub-circuit is connected to a first light emitting device, a second terminal of the second driving sub-circuit is connected to a second light emitting device, and a driving current flowing from the first driving sub-circuit to the first light emitting device is in an opposite direction to a driving current flowing from the second driving sub-circuit to the second light emitting device, wherein the first terminal of the first driving sub-circuit is different from the second terminal of the first driving sub-circuit, and the first terminal of the second driving sub-circuit is different from the second terminal of the second driving sub-circuit; and the charging sub-circuit is configured to charge the capacitor, and when the capacitor is discharged, 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.
