Claim 16:
17. A driving method for the pixel circuit according to claim 1, comprising:
in a reset stage, inputting a first power supply signal to the first power supply signal terminal, inputting a second power supply signal to the second power supply signal terminal, inputting a first scanning signal to the first scanning signal terminal, inputting a second scanning signal to the second scanning signal terminal, inputting a light-emitting control signal to the light-emitting control signal terminal, inputting a data signal to the data signal terminal, writing, by the driving control sub-circuit, a voltage of the first power supply signal to a first end of the capacitor and a voltage of the second power supply signal to a second end of the capacitor, and writing, by the input sub-circuit, a voltage of the data signal to the first node;
in a compensation stage, controlling, by the driving control sub-circuit, a voltage at the first end of the capacitor to be constant and a voltage at the second end of the capacitor to be a voltage difference between the voltage of the data signal and a threshold voltage of a driving transistor; and
in a light-emitting stage, by allowing the first power supply signal at a first level and the second power supply signal at a second level in a first light-emitting stage, writing the voltage at the second end of the capacitor to the second node, and controlling the first light-emitting element to emit light and the second light-emitting element not to emit light; and by allowing the first power supply signal at the second level and the second power supply signal at the first level in a second light-emitting stage, writing the voltage at the second end of the capacitor to the third node, and controlling the second light-emitting element to emit light and the first light-emitting element not to emit light.
