Abstract

The invention provides a transparent conductive structure with a metal grid. The transparent conductive structure comprises a transparent substrate, a first metal grid structure, a first transparent insulating layer, a second metal grid structure and a second transparent insulating layer, wherein the transparent substrate is provided with an upper surface and a lower surface opposite to the upper surface; the first metal grid structure is arranged on the upper surface of the transparent substrate; the first transparent insulating layer encircles the first metal grid structure and covers the upper surface of the transparent substrate; the second metal grid structure is arranged on the lower surface of the transparent substrate; the second transparent insulating layer encircles the second metal grid structure and covers the lower surface of the transparent substrate. The transparent conductive structure is provided with the first and second transparent insulating layers, and moisture in an environment can be isolated so as to be prevented from reacting with the first and second metal grid structures to cause metal ion migration.

Description

technical field [0001] The invention relates to a transparent conductive structure with a metal grid, in particular to a transparent conductive structure with a transparent insulating film. Background technique [0002] In the past, most common touch panels used indium tin oxide (ITO) as the transparent conductive material. However, compared with the resistance value of metal, the surface resistance value (150-400Ω / □) and line resistance value (10,000-50,000Ω / □) of ITO are both higher. When the area of ​​the touch panel is larger, the total surface resistance of the touch panel also increases. In this way, the response speed of the touch panel is reduced, or the sensitivity is not good. Therefore, touch panels with metal grids made of silver as a conductive material have gradually replaced traditional ITO touch panels. [0003] Although silver has a very small resistance value, silver itself has relatively large chemical activity, so it is easy to dissociate silver ions f...
