Resistive touchscreens are a type of display technology that registers touch through pressure. They consist of two thin layers separated by a small gap. When pressure is applied to the top layer, it makes contact with the bottom layer, completing an electrical circuit that registers the touch. These screens are commonly used in devices like ATM machines, industrial equipment, and handheld gaming consoles. They can be operated with fingers, styluses, or other objects, making them versatile in various environments. However, they typically do not support multi-touch gestures like capacitive touchscreens do.
