Transparent electromagnetic shield and method of manufacturing
First Claim
1. A transparent electromagnetic shield adapted for use on an information display device in electronic equipment comprising first and second transparent substrates each having major front and back surfaces with a front surface of one substrate adapted to be mated together with a back surface of the other, a conductive wire screen interposed between said first and second substrates in physical contact with one of said mating front and back surfaces thereof, and a single layer of polymer laminating material interposed between said screen and the other of said mating surfaces to bond said screen thereto, said layer of polymer laminating material filling the apertures in said screen and contacting portions of said one mating surface to bond said screen thereto and to bond said first and second substrates together.

Abstract
A transparent electromagnetic shield adapted for use on an information display device in electronic equipment. First and second transparent substrates each having major front and back surfaces are adapted to be mated together with a front surface of one substrate facing a back surface of the other. A conductive wire screen is interposed between the first and second substrates in physical contact with one of the mating front and back surfaces thereof and a single layer of polymer laminating material is interposed between the screen and the other of the mating surfaces. The layer of polymer laminating material fills the apertures in the screen and contacts portions of both mating surfaces to bond the screen and the two substrates together. An embodiment in which the wire screen is provided in contact with a conductive transparent optical coating on one of the mating surfaces of the substrates is also disclosed. A conductive metal tape is wrapped around the edge of the substrate in contact with the wire screen to serve as a bus bar contact to the screen, enabling use of a screen the same size as the substrate.

10. In a method for forming a transparent electromagnetic shield for use on an information display device in electronic equipment, the steps of:
-
disposing a conductive wire screen across and in contact with one major surface of a first transparent substrate; disposing over said conductive wire screen a sheet of polymer laminating material; disposing over said sheet of polymer laminating material a second transparent substrate having a major surface adapted to mate with said major surface of said first substrate; and applying pressure and heat to the assemblage of said first and second substrate, said screen and said sheet of laminating material to bond said assemblage together. - View Dependent Claims (11, 12, 13, 14, 15)
