LED smart television A LED smart television is a type of television that uses LED (Light Emitting Diode) technology for its display. LED technology allows for a thinner and more energy-efficient display compared to older LCD (Liquid Crystal Display) technology. In addition to the LED display, a smart television has built-in internet connectivity and the ability to access online content and streaming services. This allows users to browse the internet, stream movies and TV shows, and access apps and social media platforms directly on their television.
