The touch screen on your phone has a grid of transparent electrodes etched onto the back of the glass plate. Each pair of electrodes is a capacitor, and the phone's circuitry measures all of the capacitances several times each second. The electric field of each capacitor--unlike that of an ideal parallel-plate capacitor--is not confined to the space between the electrodes. Instead, part of each capacitor's electric field extends above the glass. When your finger touches the screen, it changes the capacitance of the pair of electrodes directly beneath your finger. The change is detected by the circuitry, which then knows where your finger is.
