Touch panel

Abstract

A touch panel includes a substrate, a transparent conductive sensing layer, and a metal sensing layer. The substrate has a first surface and a second surface opposite to each other. The first surface is close to an operating surface of the touch panel, and the second surface is away from the operating surface of the touch panel. The transparent conductive sensing layer is disposed on the first surface and has plural first electrode patterns. The metal sensing layer is disposed on the second surface and has plural second electrode patterns, in which the second electrode patterns form a metal mesh structure. The first electrode patterns and the second electrode patterns define a sensing unit array.

Description

technical field [0001] The invention relates to a touch panel, in particular to a touch panel with a transparent conductive sensing layer and a metal sensing layer. Background technique [0002] In recent years, thin and light flat panel displays have become widely used displays for various electronic products. In order to achieve the purpose of convenience, simple appearance and multi-functionality, many information products have changed from traditional input devices such as keyboards or mice to touch panels (Touch Panel) as input devices. [0003] With the rapid development of the technology of flat-panel displays and touch input devices, in order to allow users to have larger visual images and provide more convenient operation modes in a limited volume, some electronic products combine touch panels and display panels. combined to form a touch display panel. [0004] The operating principle of the touch panel is that when a conductive object (such as a finger) touches t...

Problems solved by technology

[0005] Since the touch panel is stacked on the display panel, the electrodes or wires on the touch panel must be made of transparent conductive materials. However, transparent conductive materials have high impedance, which will cause problems in large touch panel applications. restricted

Alternatively, some people use a metal mesh design, but the thin lines of the metal mesh will produce a blurred image due to the overlap of the lines, the Moiré phenomenon (moiré phenomenon)
