Abstract:
Disclosed is a driving circuit, comprising first to fourth electrical switches, a driving electrical switch and capacitor. The control end and second end of the first switch are coupled to a driving scan line and second end of the driving switch. The control end, first end and second end of the driving switch are coupled to the capacitor, a second end of the second switch and a first end of the fourth switch. A control end of the second switch is coupled to the driving scan line. The control end of the third switch respectively is coupled to a first compensation scan line and receives a direct current voltage. The control end and second end of the fourth switch are coupled to a compensation scan line and an anode of an organic light emitting diode. The capacitor is coupled to a cathode of the organic light emitting diode and grounded.
