touch display screen.?? Nickel-gold coating, the outer conductive layer of the five-wire resistive touch screen uses a highly ductile nickel-gold coating material. Because the outer conductive layer is frequently touched, the use of a ductile nickel-gold material is to extend the service life However, the process cost is relatively high. Although the nickel-gold conductive layer has good ductility, it can only be used as a transparent conductor. It is not suitable as a working surface of a resistive touch screen because of its high conductivity and the metal is not easy to achieve a uniform thickness. Floor.
