Problems solved by technology

[0002] If the touch panel is processed in a layer-by-layer lamination process, it is easy to cause inaccurate lamination alignment, increase the thickness and weight of the touch panel, and reduce the light transmittance and touch sensitivity of the touch product. It is difficult to improve the quality
When processing transparent conductive materials, a large amount of transparent conductive materials need to be etched away to form the corresponding induction line pattern, resulting in a large amount of etching waste liquid and serious environmental pollution; and the color difference of the touch panel is large, and the etching marks are obvious

Abstract

Disclosed is a method for manufacturing a touch panel of the grid-pattern type, comprising the steps of: etching a transparent conductive material to form nonconductive regions in a grid pattern by using photoresist technology, then electroplating a metallic conductive material thereon, affixing a photoresist film onto the metallic conductive material, and forming metal wiring by exposing, developing and etching thereon. The method can reduce the etching traces, and decrease the etching waste liquid so that it is beneficial for environmental protection, and it is simple to operate, which can reduce manufacturing costs.

Description

technical field [0001] The invention relates to a method for manufacturing a grid pattern touch panel, which belongs to the technical field of touch panel manufacturing. Background technique [0002] If the touch panel is processed in a layer-by-layer lamination process, it is easy to cause inaccurate lamination alignment, increase the thickness and weight of the touch panel, and reduce the light transmittance and touch sensitivity of the touch product. It is difficult to greatly improve the quality. When processing transparent conductive materials, a large amount of transparent conductive materials need to be etched away to form the corresponding sensing line pattern, resulting in a large amount of etching waste liquid and serious environmental pollution; moreover, the color difference of the touch panel is large and the etching marks are obvious. [0003] The present invention can perform photoresist etching on different depth layers of the touch panel by adopting photore...
