Resistive
Touchscreen
(for 90% of all touchscreen applications)
The resistive touchscreen uses a glass panel overlay with a uniform resistive
coating. A polyester coversheet is tightly suspended over the top of
the glass, separated by small, transparent insulating dots. The coversheet
has a hard durable coating on the outer side and a conductive coating
on the inner side. 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.
