Patent ID: 8847392

Claim:
A panel-type input device comprising: a pair of electrode plates, each electrode plate having a substrate and a conductive coat provided on a surface of said substrate, said conductive coat of said each electrode plate being formed from a polymer, said pair of electrode plates being assembled with each other in a relative arrangement such that conductive coats of said electrode plates are facing and spaced from each other while permitting a conductive contact between said conductive coats, said conductive coat of said each electrode plate being divided into a detecting area so that a touch input can be detected, and an inoperative area located around said detecting area and having a surface resistivity higher than a surface resistivity of said detecting area; pairs of electrodes, a first pair corresponding to said detecting area of said conductive coat of a first electrode plate and a second pair corresponding to said detecting area of said conductive coat of a second electrode plate, said electrodes of each pair being provided on a corresponding detecting area at opposing locations on the corresponding detecting area for applying a voltage to the corresponding detecting area; and conductors, each conductor being connected to one of said electrodes and formed on said inoperative area of said conductive coat of a respective electrode plate, wherein said each conductor is electrically isolated from said detecting area of the respective electrode plate.
