Abstract
A pixel circuit of a display panel is provided, including a first, second, third, fourth, fifth switch, a first capacitor and a diode. The first switch is connected with a positive supplied power voltage. The second switch is connected with the first switch and a data line. The third switch is connected with the first and second switch, generating an emission current as a driving transistor. First end of the first capacitor is connected with the first, second and third switch. Second end of the first capacitor is connected with the third, fourth and fifth switch. The fifth switch is connected with a first initial voltage. Anode of the diode is connected with the third and fourth switch while its cathode is connected with a negative emission source voltage. By configuration of the disclosed pixel circuit, a power rail emission current is independent, without being involved with initial voltages.
