ABSTRACT:
A faceplate for a touch-sensitive display includes, on an outermost surface, a pattern of electrode-regions separated by spaces. A base-coating is deposited on the surface and extends continuously over the surface. The electrode-regions are formed from a layer of a conductive transparent metal-oxide deposited on the base-coating. The electrode-regions and spaces are overcoated by a protective-layer of an insulating material. For light incident on the faceplate at about normal incidence photopic reflectivity in the protective-layer-overcoated electrode-regions is within plus or minus ten percent of photopic reflectivity in the protective-layer-overcoated spaces.
