Television screens are flat or curved surfaces that display moving images and sound for entertainment, news, and education. They come in various sizes and types, including LCD, LED, and OLED, each offering different levels of brightness, color accuracy, and energy efficiency. The screen works by using pixels, which are tiny dots that combine to create the images we see. Modern television screens can connect to the internet, allowing users to stream content from platforms like Netflix and YouTube. Many screens also support high-definition (HD) and ultra-high-definition (4K) resolutions, providing clearer and more detailed visuals. Additionally, features like smart TV capabilities enable access to apps and services directly from the screen.
