Abstract
A resistive touch screen, comprising: a) a substrate; b) a first conductive layer located on the substrate; c) a flexible cover sheet having integral compressible spacer dots; d) a second conductive layer located on the flexible cover sheet between and over the integral spacer dots; and e) an insulative layer located on the second conductive layer locally over the integral spacer dots.

A method of making a resistive touch screen, comprising the steps of:
- a) providing a substrate;
- b) forming a first conductive layer on the substrate;
- c) providing a flexible cover sheet having integral compressible spacer dots on the cover sheet;
- d) forming a second conductive layer on the flexible cover sheet between and over the integral compressible spacer dots;
- e) forming an insulative layer locally on the second conductive layer over the integral compressible spacer dots;
- and
- f) locating the flexible cover sheet over the substrate such that when a force is applied to the flexible cover sheet 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.
