|1. (WO2018076708) PIXEL DRIVING CIRCUIT AND DRIVING METHOD THEREFOR, DISPLAY SUBSTRATE, AND DISPLAY DEVICE|
|Applicants:||BOE TECHNOLOGY GROUP CO., LTD.
|Title:||PIXEL DRIVING CIRCUIT AND DRIVING METHOD THEREFOR, DISPLAY SUBSTRATE, AND DISPLAY DEVICE|
A pixel driving circuit and a driving method therefor, a display substrate, and a display device. The pixel driving circuit comprises N pixel driving units (PD1, PD2, PD3) connected with a same data line, and an nth pixel driving unit (PD1, PD2, PD3) is used for driving an nth light emitting element (ELn) to emit light, where N is an integer greater than 1, n is a positive integer less than or equal to N. The nth pixel driving unit (PD1, PD2, PD3) comprises an nth reset module (11), an nth drive transistor (D-n, D-1, D-2, D-3), an nth charging/discharging module (12), an nth compensation control module (13), and an nth light-emitting control module (14).
