5-Wire Resistive Touch Screen
How it works
5-Wire resistive touch screen is the preferred solution for applications requiring durability and reliability over time. Similar to the 4-Wire technology, 5-Wire touch screen also consists of a conductive bottom layer (ITO Glass or ITO 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 and the top layer acts only as a voltage measuring probe. Therefore, the touch screen works properly even with damages or scratches on the top layer.
