Abstract:
The present disclosure provides a pixel driving circuit, a display device, and a driving method. The pixel driving circuit comprises a driving transistor, a light emitting element, a first capacitor, a second capacitor, a write circuit, and a first switch transistor. The write circuit is configured to write a reference level to a second terminal of the first capacitor during a vertical blanking stage, and write a data level to a second terminal of the second capacitor during a effective display stage. The first switch transistor is configured to write a voltage of a first voltage terminal and a threshold voltage of the driving transistor to a first terminal of the first capacitor during the vertical blanking stage and is turned off during the effective display stage.
