Abstract
An AMOLED pixel driving circuit includes: first to third thin film transistors, a capacitor and an organic light emitting diode; a gate of the first thin film transistor receives a first scan signal, a source receives a data signal, and a drain is coupled to a first end of the capacitor; a gate of the second thin film transistor receives a second scan control signal, and a source is coupled to a second end of the capacitor, and a drain is coupled to an anode of the organic light emitting diode; a gate of the third thin film transistor is coupled to the second end of the capacitor, a source receives a first power source signal, and a drain is coupled to the anode of the organic light emitting diode; a cathode of the organic light emitting diode receives a second power source signal.
