Touch window and LCD using the same
First Claim
1. A touch window, comprising:
- a transparent window;
a sensing unit disposed on the transparent window and sensing a contact through sensing electrode patterns;
wiring patterns electrically connected to the sensing electrode patterns;
a metal pattern part connected with ends of the wiring patterns;
a printed pattern disposed on the transparent window; and
an icon disposed between the transparent window and the metal pattern part;
wherein the metal pattern part includes a light transmitting pattern that controls light transmittance;
wherein the sensing unit, the wiring patterns, and the metal pattern part each is made of at least one selected from a group consisting of Ag, Al, and Cu;
wherein the metal pattern part includes or is coated with any one reflective material of TiO2, CaCO3, BaSO4 and Polystyrene (PS);
wherein the light transmitting pattern comprises a hole transmitting light,wherein the metal pattern part comprises metal particles reflecting light, andwherein the icon having an opened structure on a function area of the printed pattern is disposed to correspond to two different layers of the metal pattern part.

Abstract
Provided is a structure capable of improving a freedom of a design and manufacturing process efficiency of an icon area of a touch window. To this end, a touch window is configured to include a sensing unit that is disposed on a transparent window and senses a contact through sensing electrode patterns, wiring parts electrically connected with the sensing electrode patterns, and a metal pattern part for a function connected with ends of the wiring parts. As set forth above, in forming the icon area of the touch window, the exemplary embodiment of the present can improve the freedom of a design while improving the manufacturing process efficiency by patterning the metal pattern part that is the signal input unit of functions formed on the surface of the transparent window at the time of implementing the sensing electrode pattern, in forming the icon area of the touch window.
