Title:
PIXEL DRIVING CIRCUIT AND DRIVING METHOD THEREFOR, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2023/197361
Kind Code:
A1
Abstract:
A pixel driving circuit and a driving method therefor, and a display panel. A second transistor (T2) stores a threshold voltage of a first transistor (T1) in a first capacitor (C1) according to a second scanning signal (Scan2), such that the effect of the threshold voltage on a driving current is compensated for; and a fifth transistor (T5) makes a voltage difference between a first node (A) and a second node (B) irrelevant to a second voltage signal according to a fourth scanning signal (Scan4), such that the problem of current attenuation caused by a voltage drop appearing in a signal transmission process is alleviated.
