Patent Images
1. A flexible, resistive touch screen, comprising:
- a) a transparent, flexible substrate;
b) a first conductive layer located on the flexible substrate;
c) a flexible transparent cover sheet having integral compressible spacer dots molded on a first side thereof; and
d) a second conductive layer located on the first side of the flexible transparent cover sheet, the peaks of the integral compressible spacer dots molded on the first side extending through the second conductive layer, whereby, when a force is applied to the resistive 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.

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.

18. A method of making a flexible, resistive touch screen, comprising the steps of:
-
a) providing a flexible, transparent substrate; b) forming a first conductive layer on the transparent substrate; c) providing a flexible transparent cover sheet; d) molding compressible spacer dots on a first side of the transparent cover sheet; e) forming a second conductive layer on the first side of the flexible transparent cover sheet, where the peaks of the integral compressible spacer dots molded on the first side extend through the second conductive layer; and f) locating the flexible transparent cover sheet over the flexible, transparent substrate such that 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. - View Dependent Claims (19, 20, 21)
