Claim Text:
1. A touch screen, comprising a substrate, wherein the touch screen further comprises: a first embossing adhesive layer, formed on a side of the substrate, wherein a first metal conductive layer is embedded in the first embossing adhesive layer, the first metal conductive layer comprises a plurality of first conductive strips mutually insulated from each other, wherein the substrate is soda lime glass or aluminosilicate glass, and siloxy of a surface of the substrate adjacent to the first embossing adhesive layer is bonded with the first embossing adhesive layer; a first electrode lead, formed on the first embossing adhesive layer and electrically connected with the first conductive strip; a transparent insulating film, comprising a first surface and a second surface opposite to the first surface, wherein the first surface faces the first embossing adhesive layer; a second embossing adhesive layer, formed on the second surface of the transparent insulating film, wherein a second metal conductive layer is embedded in the second embossing adhesive layer, the second metal conductive layer comprises a plurality of second conductive strips mutually insulated from each other; a second electrode lead, formed on the second embossing adhesive layer and electrically connected with the second conductive strip; and a first slot provided in the transparent insulating film, and a second slot provided in the second embossing adhesive layer, wherein the first slot and the second slot both directly face a free end of the first electrode lead, and a free end of the second electrode lead is positioned around the second slot; wherein the first electrode lead and the second electrode lead are both a grid structure formed by cross-connecting of conductive wires in a grid; wherein the first conductive strip and the second conductive strip each comprises a conductive grid composed of a plurality of metal wires, wherein projection of the conductive grid of the first conductive strip on the second metal conductive layer overlaps the conductive grid of the second conductive strip; wherein a strip-shaped first connecting portion formed by cross-connecting conductive wires in a grid is provided at an end of the first electrode lead, and the first connecting portion is wider than other parts of the first electrode lead; and a strip-shaped second connecting portion formed by cross-connecting conductive wires in a grid is provided at an end of the second electrode lead and the second connecting portion is wider than other parts of the second electrode lead; wherein a first electrode tieline is connected to the strip-shaped first connecting portion and a second electrode tieline is connected to the strip-shaped second connecting portion, and the first electrode tieline and the second electrode tieline are rectangular and continuous conductive wires, and wherein the first electrode tieline is electrically connected with at least two metal wires of the first conductive strip, the second electrode tieline is electrically connected with at least two metal wires of the second conductive strip; wherein the second embossing adhesive layer is formed directly on the second surface of the transparent insulating film.
