Pixel driving circuit, display apparatus, and driving method

A pixel driving circuit, comprising:

• a driving transistor, a light-emitting device, a data writing sub-circuit, a threshold compensation sub-circuit, and a first light-emitting control sub-circuit;
• wherein
• the driving transistor is configured to, based on a threshold voltage of the driving transistor and a data voltage, generate a drive current;
• the data writing sub-circuit is coupled to a gate of the driving transistor, and is configured to, in response to a signal at a scanning signal terminal, input the data voltage at a data signal terminal into the gate of the driving transistor;
• the threshold compensation sub-circuit is coupled to the driving transistor, and is configured to, in response to a signal at a compensation signal terminal, provide the threshold voltage of the driving transistor to the gate of the driving transistor;
• and
• the first light-emitting control sub-circuit is coupled to the driving transistor, and is configured to, in response to a signal at a control signal terminal, provide the drive current generated by the driving transistor to the light-emitting device.
