The 2010 Sharp Aquos models that recently came out in Japan are LED backlit, though they don't employ local dimming.
While LED may not be the be-all-and-end-all of screen/picture quality, the new Aquos use UV2A screens and they should have better contrast and uniformity than edge-lit screens.
Not sure if the new LED Aquos have made it to Europe or America yet though. Model I am looking at is a 40" (LC-40SE1) and am trying to decide between it and the 40" EX700.
I live in Japan, so can buy immediately once i make my choice....but its a hard choice to make.
