Summary: | A pixel driving circuit, comprising a driving thin-film transistor; a voltage-stabilizing capacitor, wherein a first end of the voltage-stabilizing capacitor is connected to a control end of the driving thin-film transistor, and a second end of the voltage-stabilizing capacitor is connected to a first end of the driving thin-film transistor; a first capacitor, wherein a first end of the first capacitor is connected to the control end of the driving thin-film transistor, and a second end of the first capacitor is connected to a second end of the driving thin-film transistor; and a light-emitting device, wherein a first end of the light-emitting device is connected to the second end of the driving thin-film transistor, and a second end of the light-emitting device is grounded. According to the pixel driving circuit, the voltage-stabilizing capacitor is added to a gate of the driving thin-film transistor, such that the voltage loss caused by a feedthrough effect can be reduced, thereby improving the display unif |
