Resistive Touch Screen

Resistive :
The structure basically consists of two layers. The top layer which is typically PET film, hard coated on the non-conductive side to prevent scratches. And the bottom layer that can be made from PET film or Glass. Then the conductive sides of the top and bottom layers are coated with ITO (Indium Tin Oxide) for superior electrical conductivity and optical transparency. These layers are separated by printed, transparent, non-conductive dots to provide the spacing. When touched, the two conductive layers come into contact and then the controller will determine the coordination by calculating the voltage at the touch point.
