5-Wire Resistive Touch Technology

When the screen is touched, the conductive coating makes electrical contact with the coating on the glass. The voltages produced are the analog representation of the position touched. The controller digitizes these voltages and transmits them to the computer for processing. AccuTouch five-wire technology utilizes the bottom substrate for both X and Y-axis measurements. The flexible coversheet acts only as a voltage-measuring probe. This means the touchscreen will continue working properly even with non-uniformity in the cover sheet's conductive coating. The result is an accurate, durable, and reliable touchscreen that offers drift-free operation. AccuTouch screens are sealed against contamination and moisture. The cover sheet is sealed to the glass substrate with an industrial-grade caulk. This prevents the wicking of fluid between the coversheet and glass. Also, AccuTouch screens are not air vented, thereby preventing fluid ingress through an air vent.
