Abstract:
Provided are a pixel circuit, a drive method, and a display device. The pixel circuit includes a light-emitting element, a drive circuit, an energy storage circuit, a switch control circuit, a first initialization circuit, and a compensation control circuit. The switching control circuit controls a first voltage terminal to be connected to a second end of the energy storage circuit in a refresh frame and a first light-emitting phase and to control the first voltage terminal to be disconnected from the second end of the energy storage circuit in a first reset phase and a second reset phase under control of a switch control signal provided by the switch control terminal; a first initialization circuit writes a first initial voltage into the control terminal of the drive circuit under control of an initialization control signal in the first reset phase and the second reset phase.
