This has been discussed many times before since the launch of the marketing term "LED TV" -
There are No LED TVs! ( now selling at all the stores )
The first thing we need to clear up is the confusion created by the marketing of “LED TVs” – there aren’t any! The so-called LED TVs are just LCD TVs that have a backlight that is made of white LED lights. The LEDs are not the display, just the backlight, nothing more! OLEDs are an entirely different emissive imaging display technology (that doesn’t use a backlight). Unfortunately, many people think they already have an LED/OLED TV at home, but they actually have an LCD TV…

If you see a TV described as ‘LED’ it's actually an LCD display with a backlight that's made of LEDs rather than another kind of light source.

LOL, last time had an argument here with someone about this also. Just because Samsung called their then TV as LED TV, he really insist it is LED TV for all. When explained about the backlighting to him...he turned a bit nasty. Oh well.
