Resistive touch screen displays and systems
First Claim
1. A touch screen, comprising:
- a rigid substrate having a top face;
a plurality of parallel conductive scan lines located on the top face of the rigid substrate;
a plurality of parallel conductive sense lines located on the top face of the rigid substrate;
a plurality of junctions where the conductive scan lines and the conductive sense lines cross, wherein the plurality of junctions are arranged in a staggered pattern and wherein, for any two adjacent columns of said sense lines, all junctions of said plurality of junctions positioned on one column of said any two adjacent columns of said sense lines are at different latitudes from all junctions of said plurality of junctions positioned on another column of said any two adjacent columns of said sense lines;
a plurality of dielectric pads located only at said junctions of the plurality of scan lines and plurality of sense lines electrically isolating the plurality of scan lines from the plurality of sense lines;
a flexible substrate having a bottom face oriented above the top face of the rigid substrate; and
a plurality of conductive features, each located only at each of said junctions on the bottom face of the flexible substrate and electrically isolated from each other,wherein the plurality of conductive features are arranged such that when the flexible substrate is flexed at least one of the conductive features completes a conductive pathway between one of the plurality of conductive scan lines and one of the plurality of conductive sense lines.
