10 inch touch screen tablet.Figure 1 is a side sectional view of a resistive touch screen. The surface that your finger touches is a hard coating to protect the underlying PET layer. The PET layer is a thin, flexible PET film that bends downward when the surface is touched, and allows the two underlying ITO coatings to contact each other and connect the circuit at this point. Between the two ITO layers is some one-thousandth of an inch thick separating fulcrum that separates the two layers. At the bottom is a transparent hard bottom layer to support the structure above, usually glass or plastic.
