The present disclosure relates to a pixel driving circuit, a display apparatus and a pixel driving method. The pixel driving circuit comprises a reset unit. The reset unit is arranged to enable the storage capacitor to store not only a data voltage but also a threshold voltage of the driving unit in the charging phase, to compensate for the driving unit in the driving phase, so that the operating current of the driving unit is not influenced by the threshold voltage. This eliminates the influence of the threshold voltage of the driving unit to the operating current of the driving unit, thereby solving the technical problem of non-uniformity of display brightness of the light-emitting elements due to inconsistency of threshold voltages and improving the display quality of the display apparatus. Further, the reset unit is moved outside an active display area, and is shared by a row of pixel driving circuits, which can significantly increase the aperture rate of the pixels. In this way, the current density of the organic light-emitting layer is reduced, thereby extending the usage life of the display panel. |
