A touch screen is a pressure-sensitive input device that is most typically utilised as a display screen. A capacitive touch screen panel is covered with a substance that holds electrical charges. When a person is touched, a charge is pulled to the point of contact, which is measured by circuits in the panel and sent to the controller for processing, basically turning humans into real-life capacitors. Both resistive and capacitive touch displays use indium tin oxide (ITO) sensors. Resistive, capacitive, infrared, and virtual touch screen technologies are examples of touchscreen technologies available on the market.
