A "screen" is a flat surface that displays images, videos, or information. It is commonly found in devices like televisions, computers, and smartphones. Screens can be made from various materials, including glass and plastic, and they use technologies such as LCD (Liquid Crystal Display) or OLED (Organic Light Emitting Diode) to produce visuals. Screens come in different sizes and resolutions, affecting the clarity and detail of the images shown. They are essential for various activities, including watching movies, playing games, and browsing the internet. Additionally, screens can be touch-sensitive, allowing users to interact directly with the displayed content.
