Touch Substrate, Manufacturing Method Thereof, and Display Device

摘要

The present invention provides a touch substrate, a manufacturing method thereof, and a display device. In the touch substrate of the present invention, first leads of a first-layer structure are connected with first patterns in a second-layer structure via first via holes, second leads of the first-layer structure are connected with second patterns in the second-layer structure via second via holes, and the first patterns and the second patterns produce mutual capacitance. Each first pattern comprises a plurality of branches radiating from the center to the circumference, each second pattern surrounds one first pattern in a mutually separated manner, and when the touch substrate is used for flexible display, the second patterns can cover the whole bent surface, so that when a user touches any place of the touch substrate, the touch substrate can quickly respond and blind spots cannot be formed.

主权项

1. A touch substrate, comprising:
a base; a first-layer structure arranged on the base, wherein the first-layer structure comprises first leads and second leads made of graphene, the first leads being connected with first signal ends, and the second leads being connected with second signal ends; an insulating layer arranged on the first-layer structure; and a second-layer structure arranged on the insulating layer, wherein the second-layer structure comprises a plurality of touch units made of graphene, each touch unit comprises one first pattern and one second pattern, wherein each first pattern comprises a plurality of branches radiating from the center to the circumference, and each second pattern surrounds one first pattern in a mutually separated manner; wherein the insulating layer comprises a plurality of via holes, wherein a first via hole is formed at a position corresponding to each first pattern and used for connecting the first pattern with the first lead, and a second via hole is formed at a position corresponding to each second pattern and used for connecting the second pattern with the second lead.
