Digital Touch Screen
Introduction:
Matrix touch screen is the preferred solution for economic applications requiring little effort on installation. It consists 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.
