Abstract
A pixel circuit, including: an input sub-circuit, a driving control sub-circuit, a light emission control sub-circuit, a driving sub-circuit, a first light-emitting element and a second light-emitting element, wherein the driving control sub-circuit comprises a capacitor; the input sub-circuit is used for providing a signal of a data signal end to a first node; the driving control sub-circuit adjusts the voltages of the first node, a second node and a third node by means of controlling the voltages at two ends of the capacitor; the light emission control sub-circuit is used for providing a signal of a first power supply signal end to the second node under the signal control of a light emission control signal end; and the driving sub-circuit is used for connecting or disconnecting the connection between the second node and the third node under the signal control of the first node.
