Capacitive touch screens are a type of display technology that detects touch through the electrical properties of the human body. When a finger touches the screen, it creates a change in the screen's electrostatic field, allowing the device to register the touch. This technology is commonly used in smartphones, tablets, and other electronic devices. Unlike resistive touch screens, which rely on pressure, capacitive screens are more responsive and can support multi-touch gestures. They provide a clearer display and are more durable, making them a popular choice for modern devices like the iPhone and iPad.
