Abstract:
The present disclosure provides a pixel circuit, a driving method and a display device. The pixel circuit includes a light-emitting element, a driving circuit, a first light-emitting control circuit, a first control circuit, a first initialization circuit and a second light-emitting control circuit. The first control circuit is configured to control to connect the first node and the control node under the control of a first scan signal; the first initialization circuit is configured to write a first initial voltage into the control node under the control of a second light-emitting control signal; the first light-emitting control circuit is configured to control to connect the power supply voltage terminal and the second node under the control of the second light-emitting control signal.
