Abstract
The present disclosure discloses an organic light-emitting pixel driving circuit, driving method and an organic light-emitting display panel. A driving transistor is to generate a driving current, a light-emitting element is to emit light; a first transistor is to transmit a first initialization voltage to the light-emitting element; a second transistor is to transmit a second initialization voltage to the driving transistor; a third transistor is to transmit a data signal voltage to the pixel driving circuit; a fourth transistor is to transmit a reference voltage to the driving circuit; a first capacitor is coupled in series between the output terminal of the third transistor and the driving transistor; a fifth transistor is to control the first capacitor; a sixth transistor is to control light emission of the light-emitting element; a second capacitor is to maintain the charge amount between the gate and source of the driving transistor.
