PIXEL DRIVING CIRCUIT, DRIVING METHOD, ORGANIC LIGHT EMITTING DISPLAY PANEL AND DISPLAY DEVICE

WIPO Patent Application WO/2018/161820

A1

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.
