HOW
IT WORKS
Matrix touch screens are the
preferred solution for economic applications requiring little effort
on installation. They consist of a conductive bottom layer (ITO
Glass or Film) and a conductive top layer (ITO Film). The ITO
coating forms rows on one layer and columns on the other. The two
layers are suspended by many very small spacer dots. When a certain
point is touched, it pushes the conductive coating on the top layer
against the coating on the bottom layer. The action results into
electrical contact functioning very similar to a
switch.
