Abstract:
1. A touch screen, comprising: a sensing layer; a driving layer; a substrate, and a shielding layer configured to shield the touch screen from an electric field, wherein the touch screen can detect multiple touches or near touches that occur at the same time and at distinct locations in a plane of the touch screen and produce distinct signals representative of the location of the touches on the plane of the touch screen for each of the multiple touches, wherein at least one of the sensing layer and the driving layer comprises a first nanostructure film, wherein the first nanostructure film is optically transparent and electrically conductive, wherein the sensing layer and the driving layer are separated by a first insulating layer, and wherein the sensing layer and the shielding layer are positioned on opposite sides of the substrate, wherein the shielding layer comprises a second nanostructure film, and wherein the second nanostructure film is optically transparent and electrically conductive.
