It'll be at least a few more years before they commercialize this and you suddenly feel compelled to toss out your
old plasma or LCD TV, but Motorola Labs is showing off a prototype for a 5-inch Nano Emissive Display, a new
technology they're predicting could be used to make a 40-inch HDTV that's one inch thick and costs less than $400
(yeah, we'll have to see about that).
UPDATE: Should have said, "...costs less than $400 to manufacture."
