Floating capacitive couplers used to enhance signal coupling in a capacitive touchpad
Abstract:
A capacitive touchpad comprised of drive electrodes and at least one sense electrodes disposed on or within an insulating substrate material, wherein an electrically floating capacitive coupler is disposed adjacent to both the drive electrodes and the sense electrode to thereby enhance signal coupling between the drive electrodes and the sense electrode caused by introduction of a pointing object.
