Title:
PIXEL DRIVING CIRCUIT AND DRIVING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/151115
Kind Code:
A1
Abstract:
A pixel driving circuit, which comprises sub-pixels (40), a thin-film transistor (30), multiple rows of scan lines (Gi, Gi+1, Gm) and multiple columns of data lines (Di, Di+1, Di+2, Dn) which are electrically connected with the thin-film transistor (30); the pixel driving circuit further comprises a scan driver (10) electrically connected with the scan lines (Gi, Gi+1, Gm) and a data driver (20) electrically connected with the data lines (Di, Di+1, Di+2, Dn), wherein, the scan driver (10) provides a first pull-down potential (VGL1) and a second pull-down potential (VGL2) for the scan lines (Gi, Gi + 1, Gm), the first pull-down potential (VGL1) is lower than the off potential of the thin-film transistor (30), and the second pull-down potential (VGL2) is lower than the first pull-down potential (VGL1).
