1. A pixel circuit comprising:

  • a light emitting device;

    a driving transistor for providing a pixel current to the light emitting device, the driving transistor having a gate terminal, a first terminal coupled to the light emitting device, and a second terminal;

    a storage capacitor provided between a data line for providing programming voltage data and the gate terminal of the driving transistor;

    a first switch transistor provided between the gate terminal of the driving transistor and the first terminal of the driving transistor; and

    a second switch transistor provided between the first terminal of the driving transistor and a bias line for providing a bias current to the first terminal of the driving transistor during a programming cycle.
