Claim Text:
1. A pixel circuit comprising a driving thin film transistor and a light-emitting diode, wherein the light-emitting diode and the driving thin film transistor are connected between a low level input terminal and a high level input terminal of a driving power supply in series, wherein the pixel circuit further comprises a first capacitor and a driving control unit, and wherein the driving control unit is connected with a gate line and a data line and comprises a second driving control transistor and a third driving control transistor, wherein a gate of the second driving control transistor is connected with the gate line, a first electrode of the second driving control transistor is connected with the second electrode of the driving thin film transistor, a second electrode of the second driving control transistor is connected with the gate of the driving thin film transistor, a gate of the third driving control transistor is connected with the gate line, a first electrode of the third driving control transistor is connected with a first terminal of the first capacitor, and a second electrode of the third driving control transistor is connected with the first electrode of the driving thin film transistor, during a data writing stage, the third driving control transistor is turned on so as to connect the first terminal of the first capacitor to the first electrode of the driving thin film transistor and connect the gate of the driving thin film transistor to the second electrode of the driving thin film transistor, such that the driving thin film transistor is turned on.
