Abstract:
The present disclosure provides a pixel circuit, a pixel driving method, a display panel and a display device. The pixel circuit includes a light-emitting element, a driving circuitry, a first energy storage circuitry, a second energy storage circuitry, a data writing circuitry and a compensation circuitry. The data writing circuitry is configured to write a data voltage into a first end of the first energy storage circuitry under the control of a gate driving signal provided by a gate line. The compensation circuitry is configured to control a control end of the driving circuitry to be electrically coupled to a second end of the driving circuitry under the control of a compensation control signal. The driving circuitry is configured to generate a driving current for driving the light-emitting element under the control of a potential at its control end.
