ABSTRACT:
A location sensitive touch panel for use on a rigid substrate. The substrate carries a first set of conductive strips. A resilient plastic membrane overlaying it carries a second set of conductive strips orthogonal to and spaced from the first set. Finger pressure can cause electrical contact between any one of the first set of strips and any one of the second set of strips. The substrate may be either flat or curved, with the membrane conforming to its contour. A vent in the membrane allows the membrane to assume its natural shape more quickly by allowing air to flow between the substrate and the membrane.
