Capacitive touch glass structure

A capacitive touch glass structure comprising:

• a glass substrate, having a colored bezel on a periphery of a side thereof, and the colored bezel defining a shaded area and a visible area surrounded by the shaded area;
• a first sensing layer, directly superposed on the glass substrate, formed by a metal oxide conductive film electrically connected onto a metal mesh, disposed on the glass substrate, having first sensing columns along a first direction in the visible area, a first isolation column being sandwiched between every adjacent two of the first sensing columns to separate and insulate the first sensing columns, conductive material of each first isolation column being divided into disconnected insulative areas, an end of each of the first sensing columns being provided with a first contact, and the first contacts being outward extended from the metal oxide conductive film to the shaded area;
• an insulative layer superposed on the first sensing layer;
• a second sensing layer, superposed on the insulative layer to make the insulative layer sandwiched between the first sensing layer and the second sensing layer, formed by a metal oxide conductive film electrically connected onto a metal mesh, having second sensing columns along a second direction in the visible area, a second isolation column being sandwiched between every adjacent two of the second sensing columns to separate and insulate the second sensing columns, conductive material of each second isolation column being divided into disconnected insulative areas, an end of each of the second sensing columns being provided with a second contact, and the second contacts being outward extended from the metal oxide conductive film to the shaded area;
• and
• a signal wire layer, superposed on the second sensing layer to make the second sensing layer sandwiched between the signal wire layer and the insulative layer, disposed within the shaded area, having first signal transmission wires and second signal transmission wires, each of the first signal transmission wires being electrically connected to one of the first contacts, an end of each of the first signal transmission wires being electrically connected to a first signal output contact, each of the second signal transmission wires being electrically connected to one of the second contacts, and an end of each of the second signal transmission wires being electrically connected to a second signal output contact;
• wherein the first direction is orthogonal to the second direction, the first sensing columns are orthogonal to the second sensing columns to constitute a capacitive sensing unit array.
