Pixel driving circuit, display panel and driving method

A pixel driving circuit, comprising:

• a driver transistor, a light-emitting device, a compensation capacitor, a threshold compensation sub-circuit, a data writing sub-circuit, a conduction control sub-circuit, and a light-emitting control sub-circuit;
• wherein the threshold compensation sub-circuit is mutually coupled to a gate of the driver transistor and a first end of the compensation capacitor, and is configured to provide a threshold voltage of the driver transistor to the first end of the compensation capacitor in response to a signal at a compensation signal terminal;
• the data writing sub-circuit is coupled to a second end of the compensation capacitor, and is configured to provide a data voltage at a data signal terminal to the second end of the compensation capacitor in response to a signal at a scan signal terminal;
• the compensation capacitor is configured to stabilize voltages at the first end and the second end;
• the conduction control sub-circuit is coupled to the second end of the compensation capacitor and a power signal terminal, and is configured to establish a conducting path between the power signal terminal and the second end of the compensation capacitor in response to a signal at a conduction control terminal;
• and
• the light-emitting control sub-circuit is coupled to the driver transistor and the light-emitting device, and is configured to provide a drive current generated by the driver transistor to the light-emitting device in response to a signal at a light-emitting control signal terminal.
