Sony had mentioned that it was working on an OLED TV during its press conference a few days ago and we finally spotted it on the CES show floor today, 1 million-to-1 contrast ratio and all. The prototype is only 27-inches, so it won't be vying for the "Biggest in Show" prize. That's not why it's important, though. OLED is a technology that doesn't require any backlighting, so power consumption goes down quite a bit. They're also supposed to be cheaper to manufacture than LCDs, but since no actual OLED TVs have hit the market yet, it might be too early to say for sure.
