Description

Touch window {TOUCH WINDOW}

The embodiment relates to a touch window.

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

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

The touch window may detect a position by disposing 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.

Such a touch window may be configured in various types according to the positional relationship of the sensing electrode and/or the wiring electrode.

Recently, in order to reduce the thickness of the touch window, research on arranging an intermediate layer such as a dielectric layer on a substrate and forming an electrode directly on the dielectric layer is underway.

At this time, when connecting the sensing electrode disposed on the dielectric layer and the wiring electrode disposed on the substrate, the adhesion of the connection electrode may be lowered due to a step difference between the dielectric layer and the substrate. When the touch window is bent in one direction, a phenomenon in which the connection electrode connecting the sensing electrode and the wiring electrode is detached occurs, thereby deteriorating the reliability of the touch window.

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

The embodiment is to provide a touch window having improved reliability.

The touch window according to the embodiment includes: a cover substrate including an effective area and an inactive area; An intermediate layer on the effective area; A wiring electrode on the ineffective region; A sensing electrode on the intermediate layer; And a connection electrode in contact with the sensing electrode and the wiring electrode, and the connection electrode is disposed to extend in at least two directions.

The touch window according to the embodiment may be disposed by extending a connection electrode connecting a sensing electrode on an intermediate layer and a wiring electrode on a substrate in at least two directions.

Accordingly, as the contact area of the connection electrode with the sensing electrode and the wiring electrode increases, adhesion of the connection electrode may be improved, thereby preventing the connection electrode from being detached from the sensing electrode or the wiring electrode.

In addition, as the connection electrodes are arranged in at least two directions, when the touch window is bent in one direction to implement a flexible touch window, that is, a curved touch window, cracks are generated in the connection electrodes in the one direction and the other direction by such bending In addition, connection electrodes in the same direction and in the same direction as the one direction may supplement this, thereby preventing defects in the touch window.

Accordingly, in the touch window according to the embodiment, since the connection electrodes are printed in at least two directions and disposed, it is possible to improve reliability by preventing a defect of the touch window.

Sapphire is a material that can be applied as a cover substrate due to its high surface strength and not only can dramatically increase the touch response speed due to its excellent electrical properties such as dielectric constant, but also can easily implement spatial touch such as hovering. Here, hovering refers to a technology that recognizes coordinates even at a distance from the display.

An effective area AA and a non-effective area UA may be defined on the substrate 100.
