Abstract
A flexible, resistive touch screen includes a transparent, flexible substrate; a first conductive layer located on the flexible substrate; a flexible transparent cover sheet having integral compressible spacer dots; and a second conductive layer located on the flexible transparent cover sheet, the peaks of the integral compressible spacer dots extending through the second conductive layer, whereby, when a force is applied to the touch screen at the location of one of the compressible spacer dots, the compressible spacer dot is compressed to allow electrical contact between the first and second conductive layers.
