Capacitive touchscreen

A capacitive touchscreen is a type of LCD screen that responds to control input from a finger without requiring the application of pressure, in direct contrast to its counterpart the resistive touchscreen. Whereas resistive touchscreens require pressure to join two thin display layers and complete an electric circuit that tells a cell phone (or other touchscreen device) where the user is touching, capacitive touchscreens instead have uniform fields of electron energy stored right on the surface of the screen. When a human finger comes in contact with and disrupts the electronic capacitor's field, the finger's location is recorded and transmitted to the device's software controls.
