Abstract

See full text

A contact input apparatus for providing a linear response throughout an active area of a touch screen assembly including a substrate, a first pattern of relatively low resistance material disposed on a first surface of the substrate and substantially along an outer perimeter thereof, and a second pattern of relatively low resistance material disposed on the first surface of the substrate and extending in substantially parallel relationship with the first pattern along an inner perimeter separately spaced inwardly from the outer perimeter of the substrate. The first and second patterns together define a resistive zone therebetween as an area on the first surface which includes a plurality of discrete resistive pathways that extend between the first and second patterns, with the resistive pathways being formed of one or more materials that have a relatively lower electrical resistivity value than the remainder of the resistive zone.
