5-Wire Resistive Touch Screen

5-Wire resistive touch screens are the preferred choice for applications still requiring a tactile touch but the need for higher durability and reliability

How it works

Similar to 4-Wire technology, the 5-Wire touch screen also consists of a conductive bottom layer (ITO Glass or Film) and a conductive top layer (ITO Film).  The fundamental structure difference between the two is in the 5-Wire technology; all the electrodes are placed on the bottom layer with the top layer only acting as a voltage-measuring probe.  Therefore   the touch screen will operate even with scratches and damage to the top film.
