Description

ELECTRODE MEMBER AND TOUCH WINDOW COMPRISING THE SAME BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

Embodiments relate to an electrode member and a touch window including the electrode member.

[0002] In recent years, a touch window has been applied to input images in a manner of touching an input device such as a finger or a stylus to an image displayed on a display device in various electronic products.

Such a touch window is typically divided into a resistive touch window and a capacitive touch window. The resistance film type touch window detects the change of resistance according to the connection between the electrodes when the pressure is applied to the input device, and the position is detected. The capacitive touch window senses the change in capacitance between the electrodes when a finger touches them, and the position is detected. Considering the convenience of the manufacturing method and the sensing power, recently, in a small model, the electrostatic capacity method has attracted attention.

Indium tin oxide (ITO), which is most widely used as a transparent electrode in such a touch window, is expensive and physically easily hit by bending and warping of the substrate, and the characteristics of the electrode are deteriorated. As a result, flexible) devices. In addition, when applied to a large size touch panel, a problem arises due to high resistance.

In order to solve such problems, active researches on alternative electrodes have been carried out. For example, studies have been made to replace ITO by forming an electrode material into a mesh shape.

There are various methods for producing such a mesh-shaped electrode. For example, there is a method of forming a pattern portion on the electrode substrate and filling the metal paste in the pattern portion.

In this case, when a touch window including such an electrode is combined with an LCD module, the electrode may be visually recognized due to the color difference between the electrode and the LCM module, thereby reducing visibility.

Accordingly, there is a demand for an electrode member and a touch window of a new structure that can solve the above problems.

The embodiment seeks to provide a touch window having improved visibility.

An electrode member according to an embodiment includes: a substrate; And an electrode portion on the substrate, wherein the electrode portion includes: a substrate having a pattern portion; And an electrode material disposed in the pattern portion, wherein the electrode material includes at least two or more electrode materials, and at least one of the electrode materials includes a black color.

The electrode member according to the embodiment can improve the visibility of the touch window and the touch device including the electrode member. In detail, the color of the electrode material in the electrode member may be controlled to be the same as or similar to the color of the touch window or the driving unit of the touch device, thereby preventing a decrease in visibility due to a color deviation of the electrode material and the driving unit.

That is, in the electrode member according to the embodiment, the color of at least one electrode material of the first electrode material and the second electrode material is opaque or formed in a black color system, for example, The incident light can be effectively reflected and the metal electrode pattern of the touch window can be prevented from being reflected by reflection according to the illumination state of the light module when the electrode member is coupled with the driving unit.

Therefore, the touch window and the touch device according to the embodiment include such an electrode member, thereby preventing the decrease in visibility due to the electrode pattern, thereby improving the overall visibility.

In addition, the touch window and the touch device according to the embodiment can improve the process efficiency because a blackening layer forming process is not necessary as an example of a separate antireflection layer by a black metallic material when the electrode member is formed.
