Abstract

The invention relates to a touch screen laser spliced pattern structure and an etching wiring method thereof in the technical field of a touch screen. A first etching wire is connected with an adjacent second etching wire at a spliced position by a first right angle bent structure; extension lines of the first etching wire and the second etching wire intersect with each other; and an intersectionangle is alpha. According to the invention, the right angle transition splicing structure is added at the oblique line splicing position, so that splicing accuracy of oblique line segments can be ensured, and a short circuit caused by splicing deviation is avoided.

Description

technical field [0001] The invention relates to a technology in the field of touch screens, in particular to a touch screen laser splicing pattern structure and an etching wiring method thereof. Background technique [0002] Such as Figure 1A with 1B Shown are the laser pattern structure diagrams of the ITO upper film and lower film in the touch screen, respectively. The ITO pattern unit in the touch screen adopts the laser process, but the distance of the laser once is limited and needs to be spliced, so it is impossible to realize such Figure 1C Ideal for etched wire routing. There is a problem of splicing deviation in the direct splicing of oblique lines and oblique lines by laser machines, and this splicing deviation will cause local short circuits. At present, most of the ITO pattern units adopt a rhombus structure, which inevitably needs to be spliced ​​with oblique lines, such as figure 2 shown. Contents of the invention [0003] Aiming at the above-mentione...
