Back-lite with local dimming TV should give better picture quality than edge-lite TV because of its contrast ratio. The advantage of edge-lite is less cost and maybe thinner. I would think not all 2010 tv are just edge-lited TV.
Last years model UNB8500 used a full array LED backlit display. the 2010 models now only use edgelit. I have not had the opportunity to see the 8500. Is it a better picture than this years models. Which one would you buy?
