Abstract
The present application discloses an organic light-emitting pixel driving circuit, a driving method and an organic light-emitting display panel. The organic light-emitting pixel driving circuit comprises: a first transistor provides an initialization signal to an anode of the organic light-emitting diode and a gate of the driving transistor; a second transistor compensates a threshold voltage of the driving transistor; a third transistor provides a data signal to the driving transistor; a fourth transistor transmits a first power supply voltage to the driving transistor; a fifth transistor controls electrical connection between the driving transistor and the organic light-emitting diode based on a signal of the second light-emission controlling signal terminal; a capacitor is used to store the data signal transmitted to the driving transistor; an organic light-emitting diode is used to emit light in response to the driving current generated by the driving transistor.
