Abstract

The present disclosure relates to the field of display technology, and in particular, to a pixel driving circuit, a pixel driving method, and a display apparatus. The pixel driving circuit includes: a first input device, a second input device, a driving transistor, a compensation sub-circuit, an isolation device, a reset device, and an energy storage device. The disclosure can eliminate the influence of the threshold voltage of the driving transistor and the voltage drop of the wire due to impedance on the driving current, ensuring that the driving currents output by the pixel driving circuits are uniform, thereby ensuring the uniformity of the display brightnesses of the pixel units, and furthermore, the first pole of the light-emitting device is reset to eliminate the influence of the signal of previous frame.
