There are two common types of touchscreen display of mobile phones which are the resistive and capacitive touchscreen. Resistive touchscreen is made by two plastic sheets like separated by very small gap that when a force or contact made on the surface of the screen, the two plastic sheets will touch each other and will act as an input to your device. In the other hand, the capacitive touchscreen consist of a glass coated with transparent conductor. So when the screen is touch by a human body (like finger) that is also an electrical conductor will result in distortion of the screen's electrostatic field, measurable as a change in capacitance.
