Document Type and Number:
WIPO Patent Application WO/2019/000928
Kind Code:
A1
Abstract:
Provided is an array substrate and a preparation method therefor, a detection method, and a display device. The array substrate comprises an insulation layer (3), and a first via hole (31) is provided in the insulation layer (3). The array substrate further comprises a detection structure (5), and the detection structure (5) comprises a first conductive structure (21), a second conductive structure (41), and an insulation structure (30) located between the first conductive structure (21) and the second conductive structure (41). The insulation structure (30) is a part of the insulation layer (3). The second conductive structure (41) comprises a first portion (411) and a second portion (412) separated from each other, and the first portion (411) and the second portion (412) separately overlap the first conductive structure (21) in the thickness direction of the array substrate. Moreover, a second via hole (32) is provided in the insulation structure (30) in the part where the first portion (411) overlaps the first conductive structure (21), and a third via hole (33) is provided in the insulation structure (30) in the part where the second portion (412) overlaps the first conductive structure (21).
