The present disclosure provides a pixel circuit. The pixel circuit comprises a light-emitting element, a driving transistor, a capacitor, a first transistor, a second transistor and a third transistor. The light-emitting element is electrically coupled to the system high-voltage terminal. The driving transistor is electrically coupled to the light-emitting element. The capacitor is electrically coupled between the first end and the gate end of the driving transistor. The first transistor is electrically coupled between the gate terminal of the driving transistor and the data line. The second transistor is electrically coupled between the first end of the driving transistor and the starting voltage end. The third transistor is electrically coupled between the second end of the driving transistor and a system low voltage end. 本公开文件提供一种像素电路。像素电路包含发光元件、驱动晶体管、电容、第一晶体管、第二晶体管以及第三晶体管。发光元件电性耦接系统高电压端。驱动晶体管电性耦接发光元件。电容电性耦接在驱动晶体管的第一端以及栅极端之间。第一晶体管电性耦接在驱动晶体管的栅极端以及数据线之间。第二晶体管电性耦接在驱动晶体管的第一端以及起使电压端之间。第三晶体管电性耦接在该驱动晶体管的第二端以及系统低电
