Let's rephrase it a bit. 'LED TV's' ARE LCD displays. It was a problem when the first LED-LCD came out, since they were marked as simply, "LED-TV" and advertised clearly distinctly differently from all the other similar LCD displays. This caused the main ill informed mass consumers to think that it was more than what meets the eye.
It was obviously a marketing ploy by Samsung. Sony's HCFL was still otherwise different from the ordinary CCFL, and yet the advertising differences were miniscule.
Yes the term "back-lit" can be thought of any light source behind the liquid crystal display, so it is applied into every set. But its used mainly for determining the position of the light source.
I would rather use "parallel and perpendicular-lit" instead
