Abstract

The invention discloses a pixel driving circuit and a driving method thereof, the pixel driving circuit comprises a driving module, wherein the driving module is used for providing driving current foran organic light-emitting structure, the organic light-emitting structure responds to the driving current to emit light, and the driving module comprises a driving transistor; a data writing module used for writing the data signal into the control end of the driving module; a first storage module used for maintaining the potential of the control end of the driving module in the light emitting stage; a first initialization module used for initializing the potential of the source electrode of the driving transistor in the initialization stage; and a second storage module used for maintaining the potential of the source electrode of the driving transistor before the data writing stage. According to the technical scheme, the driving function of the pixel driving circuit is achieved, and meanwhile the problem of display ghost shadow is solved.

Description

Technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a pixel driving circuit and a driving method thereof. Background technique [0002] The organic light-emitting display device includes a plurality of pixels, each pixel includes a pixel driving circuit and an organic light-emitting structure. The driving transistor in the pixel driving circuit provides a driving current to the organic light-emitting structure. The organic light-emitting structure is Glow under the action. [0003] When the organic light-emitting display device is switched between display screens of different gray levels, the displayed screen after the switch will have an afterimage problem, that is, the display screen after the switch will be affected by the display screen before the switch, which affects the display effect of the display device . Summary of the invention [0004] The present invention provides a pixel driving circuit and...
