Touch panel and manufacturing method thereof

Abstract

The invention provides a touch panel and a manufacturing method thereof. The touch panel comprises a plurality of first electric conducting patterns and a plurality of second electric conducting patterns, wherein the first electric conducting patterns and the second electric conducting patterns are arranged on a substrate, form an electric conducting structure, and are insulated from one another. The extension direction of each first electric conducting pattern is the first direction, and the extension direction of each second electric conducting pattern is the second direction. Each first electric conducting pattern comprises a plurality of first parallel metal lines and a plurality of second parallel metal lines. The first metal lines and the second metal lines form a plurality of square grids. A first acute angle is formed between each first metal line and the first corresponding direction. Each second electric conducting metal line comprises a plurality of third parallel metal lines and a plurality of fourth parallel metal lines. The third metal lines and the fourth metal lines form a plurality of square grids. A second acute angle is formed between each third metal line and the first corresponding direction. The first acute angle is different from the second acute angle.

Description

technical field [0001] The invention relates to a touch device, in particular to a touch panel for detecting a user's touch operation. Background technique [0002] Electronic devices with touch function are widely used in the public society. In order to make the sensing element transparent, the electrodes are made of transparent conductive materials, such as Indium Tin Oxide (ITO). However, such The material resistance value is high, and the raw material is expensive. So far, some touch panels use mesh metal wires to make touch sensing electrodes, wherein the mesh metal wires are composed of grids formed by interlacing ultra-thin metal wires periodically. For a touch panel with double-layer mesh metal wires, the upper and lower layers of mesh metal wires are more likely to overlap in position, that is, the projections of the upper and lower layers of mesh metal wire grids on the substrate overlap each other , so as to produce a visual effect of interference moire (Moire),...

AI Technical Summary

Problems solved by technology

For a touch panel with double-layer mesh metal wires, the upper and lower layers of mesh metal wires are more likely to overlap in position, that is, the projections of the upper and lower layers of mesh metal wire grids on the substrate overlap each other , resulting in the visual effect of interference ripple (Moire), which makes the visual effect of the touch panel poor
