Pixel driving circuit and driving method thereof, display device

A pixel driving circuit, comprising:

• a light-emitting driving circuit, a light-emitting component, a gate-source voltage adjustment circuit, a data writing circuit, and a storage circuit, wherein:
• a control end of the light-emitting driving circuit is electrically connected with a first node, a first end of the light-emitting driving circuit is electrically connected with a second node, and a second end of the light-emitting driving circuit is electrically connected with the light-emitting component;
• the gate-source voltage adjustment circuit is electrically connected with at least one of the first node and the second node, the gate-source voltage adjustment circuit is also electrically connected with an adjustment voltage terminal, and the gate-source voltage adjustment circuit is configured to adjust at least one of a voltage of the first node and a voltage of the second node, so as to increase a modulus value of a voltage difference between the control end and the first end of the light-emitting driving circuit;
• the data writing circuit is configured to write a data signal to the first end of the light-emitting driving circuit under control of a scan signal output from a current scan line;
• and
• the storage circuit is configured to store the data signal.
