Abstract
An organic light-emitting pixel driving circuit, a driving method thereof, and an organic light-emitting display panel are provided. The organic light-emitting pixel driving circuit includes a light-emitting element, a driving transistor, a first and a second initialization modules, a threshold detection module, a data write-in module, and a storage module. The driving transistor is configured to drive the light-emitting element. The first initialization module is configured to transmit a signal carried by a reference voltage line to the driving transistor. The second initialization module is configured to transmit a signal carried by an initialization signal line to the light-emitting element. The threshold detection module is configured to detect a threshold voltage of the driving transistor. The data write-in module is configured to transmit a signal carried by a data line to the pixel driving circuit. The storage module is configured to store a signal written in by the data line.
