[0035] The present invention provides an AMOLED pixel unit driving circuit for driving an OLED, and the AMOLED pixel unit driving circuit includes:
[0036] For the switch unit, the first input terminal is connected to a current source that provides charging current, and the second input terminal is connected to the OLED;
[0037] A storage capacitor, the first terminal is connected to the output terminal of the switch unit, and the second terminal is connected to the low level;
[0038] Driving a thin film transistor, the gate is connected to the first end of the storage capacitor, and the source is connected to a low level;
[0039] And shunt unit, one end is connected to low level;
[0040] The switch unit is used for turning on the path from the first input terminal to the drain of the driving thin film transistor and the second terminal of the shunt unit during the first time period, so as to charge the storage capacitor by the current source and disconnect the second terminal.
