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.

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

In recent years, in order to reduce the thickness of the touch window, research is being conducted on arranging an intermediate layer such as a dielectric layer on a substrate and forming an electrode directly on the dielectric layer.

At this time, when the sensing electrode disposed on the dielectric layer and the wiring electrode disposed on the substrate are connected, the adhesion of the connection electrode may be reduced due to the step difference between the dielectric layer and the substrate. When the touch window is bending in one direction, there is a phenomenon that the connection electrode connecting the sensing electrode and the wiring electrode is disappeared, thereby reducing the reliability of the touch window.

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

The embodiment attempts to provide a touch window with improved reliability.

A touch window according to an embodiment includes: a cover substrate including a valid region and a non-valid region; An intermediate layer on said effective area; A wiring electrode on the non-effective region; A sensing electrode on the intermediate layer; And a connection electrode contacting the sensing electrode and the wiring electrode, wherein the connection electrode extends in at least two directions.

The touch window according to the embodiment may be arranged to extend the connection electrode connecting the sensing electrode on the intermediate layer and the wiring electrode on the substrate in at least two directions.

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

In addition, when the connection electrode is arranged in at least two directions, when a flexible touch window, that is, a curved touch window is formed by bending the touch window in one direction, cracks are generated in the connection electrodes in the direction different from the one direction The connection electrodes in the same direction as the one direction can supplement the connection electrodes, thereby preventing the touch window from being defective.

Accordingly, in the touch window according to the embodiment, the connection electrodes are printed and arranged in at least two directions, thereby preventing the touch window from being defective and improving the reliability.

In detail, the substrate may include chemically tempered glass such as soda lime glass or aluminosilicate glass, or may include plastics such as polyethylene terephthalate (PET) or polyimide (PI) .

Sapphire has excellent electrical properties such as dielectric constant, which not only greatly improves the speed of touch reaction but also can easily realize space touch such as hovering and is applicable as a cover substrate because of its high surface strength. Here, hovering means a technique of recognizing coordinates even at a small distance from the display.

In the substrate 100, a valid region AA and a non-valid region UA may be defined.
