Abstract:
A method of manufacturing a plurality of flexible, capacitive touch sensors, comprising:providing a thin, flexible, transparent substrate, said substrate having a first side, a second side and being sufficiently large for division into a plurality of separate sections, each of said sections corresponding to one of said capacitive touch sensors; causing said substrate to pass a plurality of processing stations; applying at one or more of said processing stations a first layer of resistive material on said first side, said first layer being thin, transparent, electrically continuous and flexible; applying at one or more of said processing stations a plurality of thin, flexible electrodes in electrical communication with said first layer, said electrodes being positioned along the peripheries of each said section and adapted to apply within each said section an electrical potential across the portion of said first layer corresponding to said section; applying at one or more of said processing stations a plurality of thin, flexible, electrical leads in electrical contact with said electrodes for transmitting electrical signals to and from said electrodes, said electrical leads being positioned along the peripheries of each said section; applying at one or more of said processing stations a plurality of thin, flexible conductive areas in electrical communication with said first layer, said conductive areas being positioned along the peripheries of each said section and forming a pattern adapted to linearize within each said section the electrical potential across the portion of said first layer corresponding to said section; and cutting at one or more of said processing stations through said first layer and said substrate along the peripheries of each said section to provide said plurality of capacitive touch sensors.
