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.

On the other hand, in recent years, a demand for a bendable touch window is increasing. Particularly, in the case of a display device used in a vehicle or the like, there are many parts where a touch window is applied to a curved surface rather than a flat surface, so that a demand for a curved touch window is increasing.

Such a curved surface touch window can be used in various technical fields such as a car in combination with other structures such as an LCD. In a touch window including such a curved surface, an electrode or the like is disposed on a substrate including a curved surface to form a touch portion. Can be adhered onto the base substrate. However, there is a problem in that the area of the curved surface portion becomes large due to the wiring electrode or the like when the touch is made on the curved surface.

Therefore, a touch window capable of solving such a problem is required.

The embodiment attempts to provide a touch window that can reduce the bezel area with improved reliability.

The touch window according to the embodiment can reduce the reliability and the size of the bezel region.

In detail, since the wiring of the sensing electrode disposed in the outer area can be connected to the wiring in the central area and connected to the printed circuit board, it is possible to reduce the area in which the wiring is arranged in the outer area, That is, the bezel area can be reduced, and the overall size of the touch window can be reduced.

In addition, when the touch part is bonded onto the base substrate, the touch can be stably bonded to the central area and the outer area with a uniform pressure, so that the touch part and the base substrate can be stably stuck in the entire area, The reliability of the touch window can be improved.

That is, since the wiring electrodes are not disposed in the outer area formed by the curved surface, the outer area can be bonded with a uniform pressure as in the center area, so that it is possible to prevent the de-filming of the touch part from occurring in the outer area.

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.

The substrate 100 may include a central region CA and an outer region OA. The center area CA and the outer area OA may be disposed adjacent to each other. The central area CA and the outer area OA may be connected to each other. Also, the central area CA and the outer area OA may be spaced apart from each other.

For example, the central area CA and the outer area OA may be partially connected to each other and partially apart from each other.

In addition, the central region CA may have a circular shape. In addition, the outer area OA may be bent with respect to the central area CA. For example, one surface of the central area CA and one surface of the outer area OA may be inclined. That is, the outer area OA may be formed as a curved surface as a whole.

The central area CA and the outer area OA of the substrate 100 are partially connected to each other and partially formed to be spaced apart from each other and the outer area OA is separated from the central area And a second area OA2 connected to the center area.
