Abstract
A pixel driving circuit, a display device, and a driving method. The pixel driving circuit includes: a driving transistor (DT), configured to generate a drive current based on a threshold voltage of the driving transistor (DT) and a data voltage; a data writing sub-circuit (), coupled to a gate of the driving transistor (DT), and configured to, in response to a signal at a scanning signal terminal (Gate), input a data voltage from a data signal terminal (Vdata) into the gate of the driving transistor (DT); a threshold compensation sub-circuit (), coupled to the driving transistor (DT), and configured to provide a threshold voltage of the driving transistor (DT) to the gate of the driving transistor (DT) in response to a signal at the compensation signal terminal (CM); and a first light-emitting control sub-circuit (), coupled to the driving transistor (DT).
