Title:
LOW-LEAKAGE ELECTROSTATIC DISCHARGE CIRCUIT, DISPLAY PANEL, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/232524
Kind Code:
A1
Abstract:
The present application provides a low-leakage electrostatic discharge circuit, a display panel, and a display device. T1, T2, and T3 connected in series are used as a first group, and T4, T5, and T6 connected in series are used as a second group. The first group and the second group are used as discharge paths for negative-voltage static electricity and positive-voltage static electricity respectively. When one group discharges static electricity, the leakage current of the other group is very small, thus reducing the impact of the leakage current of the electrostatic discharge circuit on a signa line voltage. The electrostatic discharge circuit is suitable for the electrostatic discharge of a folding area of a flexible folding screen.
