Description

touch window {TOUCH WINDOW}

Embodiments relate to touch windows.

Recently, in various electronic products, a touch window for inputting an image by contacting an input device such as a finger or a stylus to an image displayed on a display device has been applied.

The touch window may be typically divided into a resistive touch window and a capacitive touch window. The resistive touch window detects a change in resistance according to the connection between electrodes when pressure is applied to the input device to detect the position. In the capacitive touch window, a position is detected by detecting a change in capacitance between electrodes when a finger touches the window. In consideration of the convenience and sensing power of the manufacturing method, the capacitive method has recently been attracting attention for small models.

The touch window may detect a position by arranging a sensing electrode and a wiring electrode connected to the sensing electrode on a substrate, and sensing a change in capacitance when a region in which the sensing electrode is disposed is touched.

In this case, the sensing electrode and the wiring electrode may be disposed on one surface of the substrate using one substrate or may be disposed on one surface of each substrate using a plurality of substrates.

When the sensing electrode and the wiring electrode are disposed on one surface of the substrate using a single substrate, the wiring electrode may be drawn out in various directions. For example, the wiring electrode may be disposed extending from an effective area to an ineffective area. .

In this case, when the wiring electrodes disposed on the effective area include metal, there is a problem in that the wiring electrodes may be visually recognized from the outside.

Accordingly, there is a need for a touch window having a new structure capable of solving the above problems.

An embodiment is to provide a touch window having improved visibility and reliability.

A touch window according to an embodiment includes a substrate; and a sensing electrode and a wiring electrode disposed on one surface of the substrate, wherein the wiring electrode includes a mesh shape, the wiring electrode includes a second mesh line and a connection mesh line, and the connection mesh line is the At least one of the mesh-shaped disconnected regions is connected.

The touch window according to the embodiment may connect a disconnected region in a mesh shape of the wiring electrode pattern by a connecting mesh line. In detail, a short region among the disconnected regions may be connected by a connecting mesh line.

Accordingly, it is possible to prevent the wire electrode from being disconnected due to the mesh shape being disconnected in the wiring electrode pattern.

In addition, by connecting a short region of the disconnected region within the wiring electrode pattern by a connecting mesh line, the disconnected region is connected while maintaining uniformity with other mesh shapes, so that the electrode is visually recognized from the outside as the uniformity of the mesh is broken it can be prevented

In addition, by connecting the disconnected area by the connecting mesh line without increasing the overall width of the wiring electrode, it is possible to reduce the dead zone area due to the increase in the width of the wiring electrode in the ineffective area.

Accordingly, the touch window according to the embodiment may have overall improved reliability and visibility.
