Problems solved by technology

However, when the laser etching line 31 has a very small line spacing (less than 80 microns) and the laser scanning speed is fast, the two vibrating mirrors move at the same time at the corner, and the laser moving path 32 is prone to deviate at this time, causing the line spacing (Pa...

Abstract

The invention discloses a laser etching circuit structure of a touch panel. The laser etching circuit structure of the touch panel comprises a plurality of laser etching line bodies and a plurality of screen-printed silver paste lines. The laser etching line bodies include first line bodies, second line bodies and third line bodies. The central paths of the two first line bodies are spaced by a first width; the central paths of the two second line bodies are spaced by a second width; the third line bodies are connected with one ends of the first line bodies and one ends of the second line bodies; the central paths of the two third line bodies are spaced by a third width; and each screen-printed silver paste line is located between the two laser etching line bodies. The third line bodies are same in length dimension, the first width and the second width are same in length dimension, and the length dimension of the third width is greater than that of the first width. Through the structure, the shortcoming of excessively small thickness or line breakage of the screen-printed silver paste lines (routing lines) caused by inconsistent line widths of the routing lines due to excessively small line spacing of the routing lines or relatively quick laser etching in a fabrication process can be improved.

Description

technical field [0001] The present invention relates to a laser etching circuit structure of a touch panel, in particular to a method of enlarging the line spacing of the hypotenuse in the limited space at the corner of the laser screen printing silver paste line, and improving the line spacing caused by the conventional process. The laser etched circuit structure of the touch panel with inconsistent line width caused by too small spacing. Background technique [0002] At present, various mobile phones, media players, navigation systems, digital cameras and other electronic products on the market are beginning to be equipped with various types of touch screens. According to their principles, they can be divided into resistive, capacitive, infrared and surface acoustic wave. Capacitive touch screens (hereinafter referred to as capacitive screens) are the most common. The functional layer of the capacitive screen is mainly composed of transparent conductive electrodes located...
