Yeah, I'm overstating it, I was mostly thinking of full array and using "common" incorrectly. I didn't mean it as "most". But you're overstating it as well if you're implying that it doesn't exist readily.
These 2013 LG's are edge lit and claim local dimming
(scroll to the bottom)
(there are others)
In fact the LG "LED Plus with local dimming" is supposed to mean just that. You'll see it in 2012 and earlier as well:
Sony has been using the phrase "Dynamic Edge LED" and coupling it with "local dimming" for a while. Not always though. Here's a sony link explaining what the term means:
"Dynamic Edge LED
Save energy and experience contrast that's off the charts.
Contrast is the difference between a good picture and a great picture. By varying the LED backlight, Sony is able to achieve a contrast so high, it can't be measured. LEDs also give better colours, a thinner profile, and higher energy efficiency when compared with fluorescent tubes. Sony's Dynamic Edge LED Backlight uses local dimming to achieve an infinite dynamic contrast ratio."
The 2013 Sony 900A line
(look in 2 places: you'll see "Dynamic Edge LED Backlight
" and "Night scenes are especially spectacular, composed of breathtaking blacks and stark contrast created by local dimming LED lighting
Here's a wild-card that I'm not sure of: The panasonic WT / DT line. They employ "intelligent local dimming", but I can't find a spec sheet that declares them full array or edge. I had thought I read that their "clear panel pros" were all alpha-IPS Edges, but I can't find that right now.
I could dig a little more if you want, but I've been bumping into the notion outside of Samsung for a while. It might be very limited in zoning, but they've been there.
