Abstract:
1. An inductive touch sensor, comprising: a driving layer to generate a magnetic field, wherein said driving layer comprises a plurality of driving electrodes, said driving electrodes are located on a plurality of driving lines; an induced layer spaced apart from said driving layer, wherein said induced layer comprises a plurality of induced electrodes, said induced electrodes are located on a plurality of induced lines, and said magnetic field induces an induction on said induced layer, wherein when one of said driving layer and said induced layer is depressed, at least one change in said induction occurs; and at least one inductive circuit connected to said driving layer and said induced layer; wherein a driving current is applied to said driving layer by a controller, therefore generating said magnetic field which induces a current in said induced layer and when the distance between said driving layer and said induced layer changed as a result of a user's touch, and said controller is capable of detecting the change in current in said induced layer to determine a touch location in two dimensional space.
