Well, jeffro23, from my own experience, there is no comparison between edge-lit and full array local dimming. Local dimming is so far above in quality. I did both Local dimming and edge lit last year and, to make a looooong story short, I returned to local dimming. (LEX8 - LW5700 - LZ9600)
If you visit all the edge-lit TV forums, there are so many people trying to reduce clouding and flashlighting.
Don't even go there. Don't try to fool yourself into thinking that an edge-lit set will make you happy, because it will not (if your care anything about PQ).
I learned my lesson. Edge-lit TV's are a waste of a hard earned dollar. The few hundred dollars more for a set that will make you eyes pop is well worth the money.
I firmly believe this.
It's basic science. How can you light something in the middle of a screen, surrounded by black, and not produce clouding? It's impossible.
Even if someone is telling you that their set does not produce flashlighting or clouding i would question their honesty. Just read the forums.
BLACK IS THE ABSENCE OF LIGHT
