From what I've read here and talking to a Samsung rep I've gathered "Direct LED" or "DLED" is not the same as full array; it's actually cheaper to produce than edge LED and uses fewer diodes across the span of the panel than a true full array set does, e.g. Sharp sets and the XBR, hence the lower price. IMO they still look pretty good, though.
