Abstract: The invention discloses a pixel driving circuit, a driving method, an organic light emitting display panel and a display device. The pixel driving circuit comprises a data writing module (1), a memory module (2), at least one first light emitting device (D1), a first driving module (3) which corresponds to the various first light emitting devices (D1) one by one, at least one second light emitting device (D2) and a second driving module (4) which corresponds to the various second light emitting devices (D2) one by one. Through mutual cooperation of each module, the voltage of a node can be switched between a positive value and a negative value by virtue of a simple structure, so that performances of the first driving module (3) and the second driving module (4) are recovered, and then the influence on the stability and the service life of the display panel due to performance offset of the first driving module (3) and the second driving module (4) is relieved.

Abstract: A substrate in an array substrate includes a light aperture region and a winding region arranged around the light aperture region. On the substrate, an orthographic projection of a first winding in each first signal line is overlapped with an orthographic projection of a second winding in a corresponding second signal line. In this way, the distance between two adjacent signal lines in the winding region is larger, and the parasitic capacitance generated between them is smaller.
