Title:
TOUCH SUBSTRATE AND TOUCH DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/189274
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a touch substrate and a touch display device. The touch substrate comprises a base substrate, a first touch electrode layer, a first insulating layer, a second touch electrode layer, a second insulating layer, and a signal line layer. The signal line layer comprises multiple second signal transmission lines, and one of multiple second touch electrodes is electrically connected to at least one of the multiple second signal transmission lines by means of at least one of multiple connection through holes; an orthographic projection of each first touch electrode on the base substrate and an orthographic projection of each second touch electrode on the base substrate have multiple first intersections, wherein one connection through hole is correspondingly provided at one first intersection, and an orthographic projection of the connection through hole on the base substrate and an orthographic projection of the first intersection on the base substrate have an overlapping region; the first touch electrode located at the first intersection has a shadow eliminating structure; an orthographic projection of the shadow eliminating structure on the base substrate covers the orthographic projection of the connection through hole on the base substrate.
