interactive screen resolution.( 2 ) Nickel-gold coating, the outer conductive layer of the five-wire resistive touch screen uses a good ductile nickel-gold coating material. Due to the frequent touch of the outer conductive layer, the use of a ductile nickel-gold material is intended to extend the use Life, but 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 very uniform thickness. It should not be used as a voltage distribution layer. It can only be used as a probe. Floor.
