X-Y Matrix Touch Screens

Resistive X-Y matrix touch screens operate by decoding or measuring a direct resistive circuit. This is done with four layers: a top polyester flex layer (coated with a thin conductive film), an adhesive spacer, a glass layer (coated with a thin conductive film) and an adhesive layer on the backside of the glass for mounting.
