First Claim
1. A capacitive touch sensor integrated with window panel, comprising:
- a transparent window panel substrate;
a non-conductive opaque decorative layer formed on a surface of said substrate along edges of the surface to define a transparent window area on said substrate;
a transparent conductive electrode pattern layer formed over the window area of said substrate and said decorative layer; and
a conductive wiring layer formed at an edge of top surface of said transparent conductive electrode pattern layer.

Abstract
The present invention relates to a capacitive touch sensor and, more particulaly, to a capacitive touch sensor integrated with window panel. The capacitive touch sensor integrated with window panel according to the present invention a transparent window panel substrate; a non-conductive opaque decorative layer formed on a surface of the substrate along the edges of the substrate to define a transparent window area (W) on the substrate; a transparent electrode pattern layer formed over the window area (W) of the substrate and the decorative; and a conductive wiring pattern layer formed at an edge of the transparent electrode pattern layer. The conductive wire pattern layer is disposed in such a manner that it is concealed by the opaque decorative layer. As the touch sensor of the present invention is integrated with the window panel, no additional substrate (PET) on which transparent electrodes are patterned is not required and the thickness of the touch sensor is can be reduced. Also, the touch sensor of the present invention does not require any adhesive for bonding to a separate substrate, which reduces its manufacturing costs.
