Title:
PIXEL DRIVING CIRCUIT AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2023/108796
Kind Code:
A1
Abstract:
A pixel driving circuit and a display panel. A detection module (400) is connected to a control end of a driving module (100), such that when a threshold voltage of the driving module (100) is measured, the detection module (400) can keep the electric potential at the control end of the driving module (100) stable, making the acquired threshold voltage of the driving module (100) accurate, thereby accurately compensating for the threshold voltage of the driving module (100), and thus improving the display uniformity and stability of the display panel.
