Description

Touch window {TOUCH WINDOW}

An embodiment relates to a touch window.

[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.

The 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.

The touch window may include a sensing electrode on a substrate and a wiring electrode connected to the sensing electrode. The touch window may detect a change in capacitance when a region where the sensing electrode is disposed to detect a position.

At this time, the sensing electrodes and the wiring electrodes 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 electrodes and the wiring electrodes are disposed on one surface of the substrate using one substrate, the wiring electrodes can be drawn out in various directions. For example, the wiring electrodes can be arranged extending from the effective area to the non- .

At this time, when the wiring electrodes disposed on the effective area include a metal, wiring electrodes can be visually recognized from the outside.

Therefore, a touch window having a new structure capable of solving the above problems is required.

In the touch window according to the embodiment, the disconnection region of the mesh shape of the wiring electrode pattern can be connected by the connection mesh line. In detail, a shorter area out of the disconnected areas can be connected by a connecting mesh line.

As a result, it is possible to prevent disconnection of the wiring electrode by disconnection of the mesh shape in the wiring electrode pattern.

In addition, by connecting the short regions of the disconnection regions in the wiring electrode pattern by the connection mesh lines, the disconnection regions are connected while maintaining uniformity with respect to the other mesh shapes. Therefore, as the uniformity of the mesh is broken, Can be prevented.

Also, by connecting the disconnection region by the connecting mesh line without increasing the overall width of the wiring electrode, it is possible to reduce the dead zone region as the width of the wiring electrode increases on the non-effective region.

Thus, the touch window according to the embodiment can have overall improved reliability and visibility.
