Display screens are electronic devices that visually present information, images, and videos. They are commonly found in devices like smartphones, tablets, computers, and televisions. Display screens work by using various technologies, such as LCD (Liquid Crystal Display) and OLED (Organic Light Emitting Diode), to create colorful and sharp visuals. These screens come in different sizes and resolutions, affecting the clarity and detail of the images shown. Higher resolution screens, like 4K or 8K, provide more pixels, resulting in clearer and more vibrant images. Display screens are essential for communication, entertainment, and productivity in modern life.
