Cleared for Takeoff
As near as I can tell, these "LED" HDTVs are actually use LCD displays with LED backlighting. LED backlighting does offer some advantages such as extended contrast (but not on a pixel by pixel basis) and the ability to strobe the image to decrease apparent motion blur so it does seem like a worthwhile feature. But there is also such a thing as a true LED display in development which uses individual LEDs for each color on each pixel (a 1920x1080 LED display would have over 6 million LEDs and the circuitry to drive them) but I haven't seen any such products on the market yet.
Yes, it is still a LCD screen, just LED backlit. The biggest difference that I notice is the resolution while watching blue ray. The old TV was a 40" Samsung LCD 780p. The new is 46" Samsung LED(LCD screen) 1080p. The difference is huge. As far as sports on the screen, they still look crappy because I don't have HD cable. Maybe next month.
I think Sony has a true LED screen on the market. 11'' for $3k. Give it a few years.
