Abstract

A touch screen laser splicing pattern structure and its etching wiring method in the field of touch screen technology, a first etching line and an adjacent second etching line are connected through a first right-angle bending structure at the splicing place; the first etching line and the The extension lines of the second etching lines intersect at an angle of α. The present invention adds a right-angle transitional splicing structure at the splicing part of the diagonal line, which can ensure the splicing accuracy of the diagonal line segment and avoid short circuit caused by splicing deviation.

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...
