LED-backlit LCD - Wikipedia

A LED-backlit LCD is a liquid-crystal display that uses LEDs for backlighting instead of traditional cold hode fluorescent (CCFL) backlighting. LED-backlit displays use the same TFT LCD (thin-film-transistor liquid-crystal display) technologies as CCFL-backlit LCDs, but offer a variety of advantages over them.
