Resistance touch screen has digital type (matrix) and simulation type (linearity). It is controlled by pressure induction. It takes one layer of glass or hard plastic plate as the root, with transparent oxidated metal (transparent conducting film) in the surface. Above it is hardened smooth plastic layer, inside it is one conducting layer. There are some tiny (less than 1/1000 inch) transparent separation points to separate the conducting layer. When we touch it, the two conducting layers will contact, then the coordinate will be found by calculating the voltage. Touch screen is widely used in many fields now because of its transparence, easy operation and reliability.
