A pixel circuit has a light emitting diode, a driving transistor, a capacitor, a first switch, a second switch, a third switch, and a forth switch. The driving transistor has a drain, coupled to a second end of the light emitting diode. The capacitor is coupled between a gate of the driving transistor and the ground terminal. The third switch is coupled between the source and the gate of the driving transistor. The fourth switch is coupled between the second end of the light emitting diode and a data line. The first switch is off, the second is on, and the third is on during the reset period; the first switch is off, the second is off, and the third is on during the programming period; and the first switch is on, the second is on, and the third is off during the display period.
