Abstract
A two-dimensional sensory structure for the capacitive touch panel is provided. The provided two-dimensional sensory structure includes a substrate having plural first metal structures and second metal structures on a first surface thereof, a dot-like insulating layer located on the substrate and composed of plural insulating dots, and an electrode layer located on the dot-like insulating layer and composed of plural conductive traces. The insulating dots are each corresponding to the first metal structures respectively, and thereby a first portion of the conductive traces arranged along a first direction are electrically connected to each other, and the conductive traces that are arranged along a second direction are electrically insulated therefrom. The thickness of the touch panel according to the invention is effectively reduced.
