Patent ID: 10304380

Abstract:
An organic light-emitting pixel driving circuit, a driving method, and an organic light-emitting display panel are provided. The pixel driving circuit includes a driving transistor, a light-emitting element, an initialization unit, a threshold detecting unit, a compensating unit, a first light-emitting control unit and a second light-emitting control unit. The initialization unit transmits a data voltage signal to a gate electrode of the driving transistor, and transmits a reference voltage signal to a source electrode of the driving transistor and an anode of the light-emitting element. The threshold detecting unit detects a threshold voltage of the driving transistor and holds at least one voltage signal inputted to the driving transistor. The compensating unit transmits a first power supply voltage signal to the gate electrode of the driving transistor. The first and second light-emitting control units are connected to first and second light-emitting control signal lines, respectively.
