Four-wire resistive technology
Contoured to fit snugly into the shape of the display, Elo’s
four-wire resistive technology consists of a glass panel
uniformly coated with electrically conductive and resistive
layers. A polyester cover sheet is tightly suspended over the
top of the glass and is separated from it by small, transpar-
ent insulating (separator) dots. The outer side of the cover
sheet is a hard, durable coating; the inner side has a con-
ductive coating. During operation, an electrical current
moves through the touchscreen. Activated by even a light
touch, the conductive coating makes contact with the coat-
ing on the glass and a touch point is registered.

The controller circuit applies a voltage gradient across the
resistive surface of the glass. The voltages at the point of
contact are the analog representation of the position
touched. The controller digitizes these voltages and trans-
mits them to the computer for processing.
