Touch substrate, preparation method thereof and touch device

Abstract

The invention discloses a touch substrate, a preparation method thereof and a touch device. The touch substrate comprises a plurality of first touch electrodes and a plurality of second touch electrodes which are arranged in a crossing manner; the first touch electrodes comprise a plurality of first electrodes which are arranged in the first direction and first connection parts which are connectedwith adjacent first electrodes, and the first connection parts comprise at least one first connection routing wire which extends in the first direction of the first connection routing wire and is used for connecting two adjacent first electrodes in the first direction, and the first connection routing wire is in a broken line shape. According to the technical scheme of the touch substrate, the preparation method thereof and the touch device, the touch substrate can be bent in the first direction, and breaking of the first connection routing wire is effectively avoided. Besides, when the second electrodes are designed to be two second electrodes which are arranged in the second direction, the touch substrate can be bent in the second direction, and the bending flexibility of the touch substrate is improved.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when the touch substrate is bent in the vertical direction, the first touch electrodes extending in the vertical direction will be bent, and stress concentration and plastic deformation will occur at the metal bridge lines. When the external force is removed, there is internal stress at this position due to the plastic deformation of the metal bridge wire. This internal stress will affect the structure, stability, and rigidity of the metal bridge wire, and it is easy to cause the metal bridge wire to break, thereby causing touch. bad
