Abstract
In an optical thin-film arrangement on a transparent optical substrate, such as a display screen, two or more conductive layers are stacked in an alternating fashion with one or more dielectric layers. The conductive layer can include, for example, indium-tin oxide (ITO), and the dielectric layer can include an index-matching material. The conductive layers can be in electrical contact with one another at their peripheries to provide EMI/RFI shielding. A structure having more than one conductive layer can be made to have the same net sheet resistance and thus provide the same degree of shielding as a conventional single-layer conductive coating but with lower reflectivity.
