AI Technical Summary

Benefits of technology

The patent describes a new electrode structure for a touch detecting sensor that has high transparency and low sheet resistance. The electrode structure includes multiple layers of conductive and non-conductive materials that are stacked on each other. The non-conductive layers may include a binder and an anti-reflection coating. The electrode structure can be used in flexible display devices and has improved performance compared to conventional transparent electrodes. The patent also describes a conductive connector for connecting the electrodes and a touch controller for detecting touch on the electrodes.

Problems solved by technology

Since ITO has insufficient flexibility, and a price rise is unavoidable due to the limited indium reserves, a substitute material thereof is desired to be developed.
The tin oxide (SnO2) and the zinc oxide (ZnO) also have insufficient conductivity and unfavorable flexibility.
However, a conventional transparent electrode material such as indium tin oxide (“ITO”) may not have such desired characteristics.

Embodiment Construction

[0035]The embodiments will be described more fully hereinafter with reference to the accompanying drawing. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of this disclosure.

[0036]It will be understood that when an element or layer is referred to as being “on”, “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,”“directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like numbers refer to like elements throughout. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0037]It will be understood that, although the terms first, second, etc. may be used h...

Abstract

An electrode structure includes: a first nonconductive layer; a first conductive layer disposed on the first nonconductive layer; a second nonconductive layer disposed on the first conductive layer; a second conductive layer disposed on the second nonconductive layer; and a third nonconductive layer disposed on the second conductive layer, where at least one of the first conductive layer and the second conductive layer includes a two-dimensional conductive material.

Description

RELATED APPLICATIONS[0001]This application claims priority to Korean Patent Application No. 10-2014-0091127 filed on Jul. 18, 2014, and all the benefits accruing therefrom under 35 U.S.C. §119, the content of which in its entirety is herein incorporated by reference.BACKGROUND[0002]1. Field[0003]The disclosure relates to an electrode structure and a touch detecting sensor including the electrode structure.[0004]2. Description of the Related Art[0005]Electrodes having various shapes and functions are used in many electrical and electronic devices such as, but not limited to, for example, a display device. These electrodes include a transparent electrode providing sufficient transparency to transmit light, together with excellent conductivity. The material of the transparent electrode includes indium tin oxide (“ITO”), tin oxide (SnO2), zinc oxide (ZnO), or the like. Since ITO has insufficient flexibility, and a price rise is unavoidable due to the limited indium reserves, a substitut...
