Abstract:
The disclosure provides a pixel circuit for driving a light emitting diode. A second terminal of a driving transistor is coupled to a first terminal of the light emitting diode, and a control terminal of the driving transistor receives a bias voltage. A coupling switch is coupled between a first terminal and the control terminal of the driving transistor and controlled by a first selection signal to be turned on or off. A first terminal of a first switch receives a display data voltage or a reference voltage, and the first switch is controlled by a second selection signal to be turned on or off. A first terminal of a second switch is coupled to a second terminal of the first switch. A second terminal of the second switch is coupled between the second terminal of the driving transistor and the light emitting diode, and the second switch is controlled by the first selection signal to be turned on or off. A first terminal of a capacitor is coupled between the second terminal of the first switch and the first terminal of the second switch, and a second terminal of the capacitor supplies the bias voltage to the control terminal of the driving transistor. An emitting switch is coupled between an operating power supply and the first terminal of the driving transistor and controlled by an emitting control signal to be turned on or off.

Claim (Index 5):
The pixel circuit according to  claim 4 , wherein the capacitor is charged so that the bias voltage is substantially equal to the voltage of the operating power supply during the initial time period, and the capacitor is discharged so that the bias voltage is substantially equal to Vth+Vref during the compensation time period, wherein Vth is the threshold voltage of the driving transistor and Vref is the reference voltage.
