Video screens are flat surfaces that display moving images and videos. They are commonly found in devices like televisions, computer monitors, and smartphones. These screens use various technologies, such as LCD (Liquid Crystal Display) and OLED (Organic Light Emitting Diode), to produce clear and vibrant visuals. Video screens can vary in size, from small handheld devices to large wall-mounted displays. They are used for entertainment, education, and communication, allowing users to watch movies, play games, or participate in video calls. The quality of a video screen is often measured by its resolution, brightness, and color accuracy.
