Embodiment 1

[0079] Example 1: First, a blackened copper alloy layer is plated on a transparent substrate by vacuum evaporation, wherein the coating atmosphere is a mixture of oxygen and argon; then, the blackened copper alloy is treated with roughening and / or anti-oxidation potions On the surface of the copper alloy layer, a roughened layer is formed on the surface of the blackened metal copper grid layer. Wherein, the coarsening and / or anti-oxidation potion includes 15% formic acid, 15% copper formate, 2% phenyltriazole, 0.5% guanidine hydrochloride and 0.5% monoethanolamine, and the rest is pure water.

Embodiment 2

[0080] Embodiment 2: First, a pure copper layer is plated on a transparent substrate by vacuum evaporation, wherein the coating atmosphere is pure argon with a purity of more than 99%; then, a copper layer is plated on a transparent substrate by vacuum evaporation. Cover the blackened copper alloy layer, wherein the plating atmosphere is a mixture of oxygen and argon; then, use roughening and / or anti-oxidation potions to treat the surface of the blackened copper alloy layer, so that the surface of the blackened metal copper grid layer A roughened layer is formed. Wherein, the coarsening and / or anti-oxidation potion includes 15% formic acid, 15% copper formate, 2% phenyltriazole, 0.5% guanidine hydrochloride and 0.5% monoethanolamine, and the rest is pure water.

[0081] The specific test method of roughness and reflectivity: use surface roughness tester (or atomic force microscope) to test the roughness of above-mentioned embodiment and comparative example touch panel; Use vis...

Abstract

The invention provides a touch panel. The touch panel comprises a transparent substrate and a blackened metal copper grid layer; and the blackened metal copper grid layer is stacked on the transparent substrate, the blackened metal copper grid layer is provided with a first surface and a second surface which are opposite to each other, the first surface is combined with the transparent substrate, and a coarsening layer is formed on the second surface. The invention further provides a manufacturing method of the touch panel. According to the technical scheme, the metal copper grid layer is further coarsened on the basis of blackening, the reflectivity of the touch panel can be remarkably reduced, the touch panel can be applied to a backlight-free electronic book and a cholesterol liquid crystal display, and the discordance of metal reflection and color under strong light is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of touch panels, in particular to a touch panel and a manufacturing method of the touch panel. Background technique [0002] Touch is everywhere. Since Apple Jobs widely used capacitive touch screens in its own products, it can be said that capacitive touch screens have almost completely replaced the original resistive touch screen technology in consumer electronics. Among them, the metal copper grid touch screen technology is an emerging cross-generation technology in the capacitive touch screen technology. It uses a copper layer with an extremely low surface resistance (the surface resistance is less than 0.1 ohms) A copper layer is deposited on an optical-grade transparent substrate by evaporation, and then a grid-shaped electrode is produced by photolithography processes. The touch screen made by using this electrode has the following advantages: (1) Invisible line: Metal Mesh technology visible...
