Abstract

The embodiment of the invention provides a pixel driving circuit and a driving method thereof, a display panel and a display device. The pixel driving circuit comprises a charging control module whichis configured to transmit a data signal from a data signal end to a first node under the control of a scanning signal from a scanning signal end; a signal storage module which is configured to be capable of storing signals from the first node or transmitting the stored signals to the first node; a first driving module which is configured to be capable of transmitting a first voltage signal from the first voltage signal end to the organic light emitting diode (OLED) element under the control of the level of the first node; and a second driving module which is configured to be capable of transmitting a second voltage signal from the second voltage signal end to the OLED element under the control of the level of the first node.

Description

technical field [0001] The present disclosure relates to the field of display technology, and more particularly relates to a pixel driving circuit and a driving method thereof, a display panel and a display device. Background technique [0002] In recent years, with the rapid development of display technology, thin-film transistor (TFT) technology has developed from the original amorphous silicon (a-Si) thin-film transistor to the current low-temperature polysilicon (LTPS) thin-film transistor, metal-induced lateral crystallization (MILC) Thin-film transistors, oxide (Oxide) thin-film transistors, etc., and the light-emitting technology has also developed from the original liquid crystal display (LCD) and plasma display panel (PDP) to the current organic light-emitting diode (OLED) display. [0003] OLED is a new generation of display device, which has many advantages compared with liquid crystal display, such as: self-illumination, fast response speed, wide viewing angle an...
