Pixel circuit of a display panel

A pixel circuit of a display panel, comprising:

• a first switch, being electrically connected with a positive supplied power voltage (PVDD);
• a second switch, being electrically connected with the first switch and a data line;
• a third switch, being electrically connected with a common terminal of the first switch and the second switch, wherein the third switch generates an emission current as a driving transistor of the pixel circuit;
• a first capacitor, having a first end and a second end, wherein the first end of the first capacitor is electrically connected with a common terminal of the first switch, the second switch and the third switch;
• a fourth switch, being electrically connected with the second end of the first capacitor and the third switch;
• a fifth switch, being electrically connected with a first initial voltage (Vinitn), wherein the second end of the first capacitor is further electrically connected with a common terminal of the third switch, the fourth switch and the fifth switch;
• and
• a diode, having an anode connected with a common terminal of the third switch and the fourth switch, and a cathode connected with a negative emission source voltage (ELVSS).
