Touch screen

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;
