Abstract

Embodiments of the present invention provide a pixel driving circuit, a driving method thereof, a display panel, and a display device, and relate to the field of display technology. The pixel drive circuit includes: an anode reset module, the anode reset module is electrically connected to the first scanning signal line, the reset signal line and the anode of the organic light emitting diode, and is used to reset the organic light emitting diode by using the reset signal under the control of the first scanning signal. The anode of the organic light-emitting diode is reset; the pull-down module is electrically connected to the pull-down signal line and the anode of the organic light-emitting diode, and is used to pull down the potential of the anode of the organic light-emitting diode by using the pull-down signal. The embodiments of the present invention are used to improve the problem of sub-pixel stealing light and the problem of voltage increase in dark state.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a pixel driving circuit and a driving method thereof, a display panel, and a display device. 【Background technique】 [0002] As an important part of the information industry, display technology has played an important role in the development of information technology. With the development of display technology, liquid crystal display panels, organic light emitting diode display panels and other types of display panels have been widely used.
