Embodiment 1

[0033] Conductive layer in electrode lead area made in a regular grid shape

[0034] This embodiment is based on the cross-sectional schematic view of the embedded metal grid conductive layer as shown in figure 1 shown. The conductive layer is the substrate PET 11 from bottom to top, with a thickness of 188 μm; an adhesion-promoting layer 12; an acrylic UV adhesive 13 with a groove structure, the groove depth is 3 μm, and the width is 2.2 μm; the groove is filled with metallic silver 14. The thickness is smaller than the groove depth, about 2 μm.

[0035] This embodiment is based on the schematic plan view of the embedded metal grid conductive layer as figure 2 shown. The conductive layer includes a transparent electrode area 21 and an electrode lead area 22 . The transparent electrode region 21 is composed of irregular polygonal random grids, the line width is 2.2 μm, the average diameter R of the grids is preferably 120 μm, and the relative transmittance is 96%. Since ...

Abstract

The invention relates to a metal grid conducting layer and a touch panel equipped with the conducting layer. Surface of the conducting layer comprises a transparent electrode area and an electrode lead area, wherein the transparent electrode area is equipped with random metal grids in irregular shapes, and the electrode lead area is equipped with metal grids in regular shapes. Grid lines of the transparent electrode area are evenly distributed in each angular direction. Said grids are filled into grooves. In the transparent electrode area of the invention, grids are adopted so that conductive filling materials are more evenly filled in the grooves and are better connected with external conductive materials. In addition, the transparent electrode composed of irregular grids would no longer generate moire fringes.

Description

technical field [0001] The invention relates to the technical field of conductive layers, in particular to a metal grid conductive layer and a touch panel equipped with the conductive layer. Background technique [0002] A touch screen is an inductive device that receives an input signal from a touch lamp. The touch screen has endowed information interaction with a new look and is a very attractive new information interaction device. The development of touch screen technology has aroused widespread concern in the information media circles at home and abroad, and has become a rising high-tech industry in the optoelectronic industry. [0003] The ITO layer is a crucial component in the touch screen module. Although the manufacturing technology of the touch screen is developing rapidly. But taking the projected capacitive screen as an example, the basic manufacturing process of the ITO layer has not changed much in recent years. It is always inevitable to need ITO coating, ...
