Screens are flat surfaces that display visual information, commonly found in devices like televisions, computers, and smartphones. They use various technologies, such as LCD (Liquid Crystal Display) and OLED (Organic Light Emitting Diode), to produce images and videos. Screens can vary in size, resolution, and purpose, serving both entertainment and productivity needs. In addition to displaying content, screens can also be touch-sensitive, allowing users to interact directly with the displayed information. This feature is prevalent in tablets and smartphones, enabling actions like scrolling, tapping, and swiping. Screens have become essential tools in daily life, facilitating communication, learning, and entertainment.
