A display is an output device that visually presents information in various forms, typically as text, images, or video. It is a key component in devices like computers, smartphones, televisions, and other electronics, serving as the primary interface between the user and the system. Modern displays use technologies such as LED, OLED, and LCD, offering high-resolution visuals, vivid colors, and fast refresh rates. Displays are essential for user interaction, making it easier to access, navigate, and engage with digital content. Their design and quality significantly impact user experience, as larger, sharper, and more responsive screens offer enhanced readability and visual comfort.
