Abstract
The present disclosure relates to a pixel driving circuit, a pixel driving method and a display device. A voltage related to a threshold voltage of a driving unit is stored in a storage unit during a compensation stage of the pixel driving circuit utilizing a charging control unit so that an operating current of the driving unit is not affected by the threshold voltage during a light emitting holding stage of the pixel driving circuit. Thus, the influence of the threshold voltage of the driving unit on an operating current thereof is eliminated and an issue in which the display luminance of the light emitting element is not uniform due to inconsistency in the threshold voltage is solved, which improves display quality of the display device.
