Abstract:
A touch-panel input device comprising:at least first and second transparent plates having faces opposed to one another and substantially parallel; a portion of said opposing faces of said at least first and second transparent plates being transparent electrically conductive surfaces with uniform surface resistance; an elastic adhesive disposed around a perimeter of said conductive surfaces, whereby said opposing faces are bonded together and separated by a sealed gap having a uniform width; a transparent insulative fluid interposed in said sealed gap, said fluid having a refraction index close to that of said transparent plates; at least one of said at least first and second transparent plates capable of resiliently flexing toward an other of said transparent plates, whereby an electrical relationship is changed between said conductive surfaces; and said relationship is related to a coordinate position on said device.
