Pixel driving circuit and driving method thereof, and display apparatus
A pixel driving circuit and a driving method therefor are provided. The pixel driving circuit includes a turn-on voltage acquiring device, a compensation device, a light-emitting controller, a data writing device, a driving transistor and a light emitting device. The turn-on voltage acquiring device acquires a turn-on voltage of the light emitting device and generates a compensation signal according to the turn-on voltage; the data writing device provides a data voltage to the gate of the driving transistor; the light-emitting controller provides a first operating voltage to a first electrode of the driving transistor; and the compensation device generates a control signal according to the compensation signal, the data voltage and the threshold voltage of the driving transistor and provides the control signal to the gate of the driving transistor; the driving transistor outputs a driving current to the light emitting device.
