Abstract

An apparatus including a touch panel display component having at least one display part and an electrically conductive part electrically isolated from the display part. The electrically conductive part forms an induction loop incorporating a magnetic field induction capability. The magnetic field induction loop is used for hearing aid coupling, wireless charging, or contactless data communication. An electrostatic discharge component may be included to provide a discharge path to protect the display.
