Abstract: An active matrix organic light emitting diode (AMOLED) circuit and an operating method thereof are disclosed herein. The AMOLED circuit includes an organic light emitting diode, a switching circuit, a compensating circuit, a driving circuit, and a reset circuit. The compensating circuit is connected to the switching circuit and includes a first capacitor. The driving circuit is configured to be driven by the compensating circuit to provide the organic light emitting diode with a driving current. The reset circuit is connected to both ends of the first capacitor and to a control line. The reset circuit is configured to change the voltage levels on both ends of the first capacitor according to the voltage level on the control line, such that one end of the first capacitor and a reference power supply are conducted and charges stored inside the first capacitor are released.
