However, because the metal mesh has the disadvantage of hindering the transmittance, the main method in the industry is to reduce the metal line width of the metal mesh and increase the aperture between the meshes
Even so, its transmittance is still not ideal, and its production yield is also affected as the diameter of the metal wire decreases.

Abstract
The invention relates to a transparent conductor for a capacitive touch panel, and is applied to the fields of electrostatic prevention for an induction layer and a display panel of the capacitive touch panel. The transparent conductor comprises a transparent substrate and a stripped micron-level metal wire grating array on the surface of the transparent substrate; and the stripped micro-level metal wire grating array comprises a plurality of metal wires. According to the transparent conductor, transparent conducting materials are arranged in a metal grating array mode instead of a metal grid mode, so that half of metal wires on the transparent substrate can be reduced, and the transmittance is greatly improved; meanwhile, defective metal wires during manufacture of the metal wires are reduced, and the production yield is improved; and as the metal conducting wires are used as the conductors and the metal wires have lower resistance, the touch panel has fast touch response speed when the metal wires are applied to the capacitive touch panel.
Description
technical field [0001] The invention relates to a transparent conductive material, which is used in the fields of the sensing layer of the capacitive touch screen, the antistatic of the display panel and the like. Background technique [0002] The touch screen is an input device that significantly improves the man-machine interface, and has the advantages of intuition, simplicity and speed. Touch screens have been widely used in many electronic products, such as mobile phones, PDAs, multimedia, public information inquiry systems, and the like. There are four main types of touch screens, including resistive, capacitive, infrared and surface acoustic wave touch screens. Among them, the capacitive touch screen has excellent performance, for example, there is no problem of mechanical movement and wear in the screen, and it has a simple structure, high light transmittance, good linearity, dustproof, fireproof, and scratch-resistant, even in the harshest environment. With stable...
