Abstract:
A touch screen comprising: a) a substrate; b) a first conductive layer located on the substrate; c) a flexible sheet comprising a substantially planar surface and integral compressible spacer dots formed thereon, each integral compressible spacer dot having a base closest to the substantially planar surface and a peak furthest from the substantially planar surface; and d) a second conductive layer located on the substantially planar surface of the flexible sheet, the peaks of the integral compressible spacer dots extending beyond the second conductive layer located on the substantially planar surface; wherein the first and second conductive layers are positioned towards each other and separated by the integral compressible spacer dots. Undercuts are formed around each integral compressible spacer dot, and the second conductive layer is electrically isolated from any conductive layer material deposited on the peaks of the spacer dots while depositing the conductive layer material on the substantially planar surface.
