Abstract: The present application discloses a pixel driving circuit for a sub-pixel in light-emitting display. The pixel driving circuit includes a driving sub-circuit comprising N driving transistors connected in series. N is an integer greater than 1. The N driving transistors include a first driving transistor having a source electrode coupled to a first input voltage port and an N-th driving transistor having a drain electrode coupled to a light-emitting diode. Additionally, the pixel driving circuit includes a power-storage sub-circuit coupled to a gate electrode of the first driving transistor and the drain electrode of the N-th driving transistor. Furthermore, the pixel driving circuit includes a charge-input sub-circuit configured to use a first control signal from a first scan line to control a connection between the gate electrode of the first driving transistor and a data line supplying a data voltage.
