Pixel driving circuit and method for driving the same, display panel and compensation

A pixel driving circuit, comprising a driving sub-circuit, a compensation sub-circuit, a first switching sub-circuit, and a second switching sub-circuit, wherein

• the driving sub-circuit has a control terminal electrically connected to a first terminal of the second switching sub-circuit, a first terminal electrically connected to a light-emitting element, and a second terminal electrically connected to a power source;
• the compensation sub-circuit has a first terminal electrically connected to the first terminal of the driving sub-circuit, and a second terminal electrically connected to the control terminal of the driving sub-circuit;
• the first switching sub-circuit has a control terminal electrically connected to a first signal input terminal, a first terminal electrically connected to the first terminal of the driving sub-circuit, and a second terminal electrically connected to an initial voltage input terminal;
• and
• the second switching sub-circuit has a control terminal electrically connected to a second signal input terminal, a first terminal electrically connected to the control terminal of the driving sub-circuit, and a second terminal electrically connected to a data signal input terminal,
• wherein the second switching, sub-circuit is configured to receive a compensated data voltage from the data signal input terminal, wherein the compensated data voltage is determined based on a threshold voltage and a mobility of the driving sub-circuit.
