18. A method for manufacturing a touch input apparatus, comprising:
-
providing a first base including a metal compound; forming a first pattern groove by irradiating laser light to one surface of the first base; forming a first sense pattern in the first pattern groove through a plating or deposition process; stacking a second base including a metal compound over the first base; forming a second pattern groove by irradiating laser light to one surface of the second base; forming a second sense pattern spaced apart from the first sense pattern over the second pattern groove through a plating or deposition process; and providing a current to the first and second sense patterns, determining a change of capacitance between the two sense patterns, and determining whether the two sense patterns are used as a sensor on the basis of the determined change of capacitance. - View Dependent Claims (19, 20, 21)
