Abstract
A pixel driving circuit and a driving method thereof, and a display device. The pixel driving circuit includes a light-emitting driving circuit, a light-emitting component and a gate-source voltage adjustment circuit. A control end, a first end and a second end of the light-emitting driving circuit are electrically connected with a first node, a second node and the light-emitting component respectively; 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.
