Resistive touch screen

Our resistive touch panel is made of two transparent ITO films with conductive ability and ITO glass. Its conductive surfaces are opposite and separated by a number of transparent spacing points in the middle. When the user operates with a finger or a stylus, the upper and lower conductive films are pressed. When the upper film is pressed, it contacts with the lower ITO glass and generates a partial voltage current. The controller measures the voltage change of the touch panel and calculates the position of the contact point.
