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 and resolution, affecting the clarity and detail of the visuals. Screens are essential for communication, entertainment, and information access. They allow users to interact with software applications, browse the internet, and watch movies. With the rise of touchscreen technology, many screens now enable direct interaction, making them more user-friendly and versatile in everyday tasks.
