Claim 0:
1. A pixel driving circuit, applied to a display panel comprising a plurality of pixels, the pixel driving circuit comprising:
a driving sub-circuit which comprises a driving transistor, wherein an input of the driving transistor is coupled to a driving voltage terminal, and an output of the driving transistor is coupled to a sub-pixel;
a data-writing sub-circuit, wherein an output of the data-writing sub-circuit is coupled between the input of the driving transistor and the driving voltage terminal, and the data-writing sub-circuit is configured to write a data voltage to the driving transistor in a compensation and writing stage; and
a voltage stabilization sub-circuit coupled to a control terminal of the driving transistor and configured to keep a voltage at the first control terminal of the driving transistor to be stable in a reset stage, wherein the driving transistor further comprises a second control terminal, the first control terminal of the driving transistor and an active layer of the driving transistor are constituted as a first stray capacitance, and the second control terminal is coupled to a direct current (DC) signal terminal, so that the second control terminal of the driving transistor and the active layer are constituted as a second stray capacitance.
