Problems solved by technology

However, when the decorative layer is made into a light color such as a light color, the shading effect of the non-black frame is not good when covering the wiring. Making it very thick leads to an increase in the thickness of the frame, which causes the climbing problem of the transparent conductive layer

Abstract

The invention discloses a touch panel which comprises a touch sensing layer, wherein the touch sensing layer comprises a silver nanowire electrode and a wiring area corresponding to the silver nanowire electrode, and the wiring material of the wiring area is silver nanowires, the length of the nano silver wire is 20-50 [mu] m, the wire diameter is less than 50 nm, and the length-width ratio is greater than 100, the thickness of the wiring area is the same as that of the silver nanowire electrode; a cover plate, which comprises a visible area and a shielding area, the shielding area is formed by coating the periphery of at least one edge of the visible area with a color coating, the color coating is located on the upper surface of the cover plate, the touch sensing layer is arranged on the lower surface of the cover plate, a groove is formed in the cover plate, the color coating is embedded into the groove, the colored coating is flush with the surface of the cover plate, and the thickness of the color coating is less than 10 microns.

Description

[0001] This application is a divisional application with an application date of September 17, 2014, an application number of 201410474228.4, and an invention title of “a touch panel”. technical field [0002] The present invention relates to the field of touch technology, in particular to a touch panel. Background technique [0003] With the rapid rise of the touch panel in the communication industry in recent years, especially the booming development of the mobile phone communication industry, the touch panel has become the first-choice product of today's imaging display devices. [0004] In the existing touch panel structure, the material of the general electrode layer is indium tin oxide (ITO), and the material of the wiring is molybdenum aluminum molybdenum (MoAlMo). The yield rate is generally low, and the indium in the indium tin oxide material used in the transparent conductive layer is a rare substance. The content of indium in the world is about 16,000 tons, which m...
