eboard interactive touch screen.Resistive touch screens are mainly controlled using pressure sensing. Its composition is a display screen and a resistive thin film screen which is closely attached to the display screen. This resistive film screen is usually divided into two layers. One is a base layer made of glass or plexiglass. The surface is coated with a transparent conductive layer. The outer layer is pressed by the hardened and scratch-resistant plastic layer that we usually directly contact. There is also a conductive layer inside the plastic layer, and the two conductive layers are separated. When we touch the screen with fingers or other objects, the two conductive layers come into contact, and the resistance changes, and the controller judges the coordinates of the contact points and performs corresponding operations according to the specific changes in resistance.
