Capacitive touchscreens are a type of display technology that detects touch through the electrical properties of the human body. They consist of a glass panel coated with a transparent conductor, usually made of indium tin oxide. When a finger touches the screen, it creates a change in the electrical field, allowing the device to register the touch. These screens are commonly used in devices like smartphones, tablets, and laptops due to their high sensitivity and ability to support multi-touch gestures. Unlike resistive touchscreens, which rely on pressure, capacitive touchscreens provide a more responsive and clearer user experience.
