A smartphone screen is a flat display that allows users to interact with their device. It typically uses LCD or OLED technology to show images, videos, and text. The screen is touch-sensitive, enabling users to tap, swipe, and pinch to navigate apps and features. Smartphone screens come in various sizes, usually measured diagonally in inches. They often have a protective layer, such as Gorilla Glass, to prevent scratches and damage. The resolution of a smartphone screen, measured in pixels, affects the clarity and sharpness of the visuals, with higher resolutions providing a better viewing experience.
