A touchscreen is a display interface that allows users to interact directly with what is shown by touching the screen with their fingers or a stylus. It eliminates the need for physical buttons or keyboards, making navigation more intuitive. Touchscreens are widely used in smartphones, tablets, ATMs, kiosks, and interactive displays. They operate through various technologies, such as resistive, capacitive, or infrared, each offering different levels of sensitivity and responsiveness. Capacitive touchscreens, common in modern devices, support multi-touch gestures like pinching and swiping. Touchscreens enhance user experience by providing quick, direct control over applications and functions. Their versatility makes them essential in consumer electronics, retail, education, and industrial settings. With advancements in technology, touchscreens continue to evolve, offering improved durability, clarity, and interactivity.
