Abstract

The embodiment of the invention provides a pixel driving circuit and a driving method thereof, a display panel and a display device, and relates to the technical field of display. The pixel driving circuit comprises an anode reset module which is electrically connected with a first scanning signal line, a reset signal line and an anode of an organic light emitting diode and is used for resetting the anode of the organic light emitting diode by using a reset signal under the control of a first scanning signal; and a pull-down module which is electrically connected with a pull-down signal line and the anode of the organic light emitting diode respectively and is used for pulling down the potential of the anode of the organic light emitting diode by utilizing the pull-down signal. According to the embodiments of the present invention, the pixel driving circuit and the driving method thereof are used for solving the sub-pixel light stealing problem and the dark state voltage rising problem.

Description
