Title:
DRIVING CIRCUIT AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2023/151135
Kind Code:
A1
Abstract:
A driving circuit and a display panel. The driving circuit comprises a light-emitting device (D), a light-emitting control module (101), and a gray-scale control module (102), wherein the gray-scale control module (102) comprises a first transistor (T1) and a second transistor (T2), and the conduction time of the first transistor (T1) partially overlaps the conduction time of the second transistor (T2), such that the light-emitting duration of the light-emitting device (D) is less than the minimum conduction time of the first transistor (T1) or the second transistor (T2). The problem that the existing driving circuit cannot realize low-gray-scale display can be solved.
