LED TV is a type of LCD television that uses light-emitting diodes (LEDs) to backlight the display instead of the cold cathode fluorescent lights (CCFLs) used in standard LCD televisions. LED TVs are more formally known as LED-backlight LCD television.LED stands for light-emitting diode and simply refers to the backlight that lights up your TV. You'll notice that LEDs are present in both OLED and QLED technology. In fact, virtually every Smart TV today uses LEDs as its lighting source.
