| Zusammenfassung: | A pixel circuit of a display panel comprises a first switch, a second switch, a third switch, a fourth switch, a fifth switch, a first capacitor and a diode. The first switch is electrically coupled to a positive power supply voltage, and the second switch is electrically coupled to the first switch and a data line. The third switch is electrically coupled to the first switch and the second switch and serves as a driving transistor to generate an emission current. The first end of the first capacitor is electrically coupled with the first switch, the second switch and the third switch, and the second end of the first capacitor is electrically coupled with the third switch, the fourth switch and the fifth switch. The fifth switch is connected to a first initial voltage. The anode of the diode is electrically coupled to the third switch and the fourth switch, and the cathode of the diode is electrically coupled to a negative emission source voltage. By adopting the pixel circuit, independent power supply rail l |
