Blame Sony's Chief Boss Howard Stringer for commenting that OLED sounds like a Norse god. But it's not. It's an ultra flat display technology with an inherently outstanding black level. Last year, Sony showed a number of small 11-inch models, together with a slightly larger prototype. The display was essentially the same this year, except that the design has been refined and the 11-incher is actually on sale now for $2500. OLED is currently expensive to manufacturer in larger screen sizes, and reportedly has a shorter life than LCD and plasma displays. But the pictures on these small screens sure looked fantastic.

Sony's new XBR8 series uses LED backlighting with local dimming. Shown here was a demo setup in which you can see a single cluster (of the many--number not specified which will be positioned behind the panel) of red, green, and blue backlights. The interesting feature here is the presence of two green LEDs. That's not so puzzling when you realize that in our HD color TV system the luminance signal is encoded with more green information than red and blue put together.

Sony, and other manufacturers as well, are big on 240Hz refresh rates this year. At CEDIA in September Sony showed one Bravia line that operates at 240Hz—the XBR7 (just beginning to ship now).

We've discussed Sony's new 4K home theater projector earlier in this running blog, but based on the crowds lining up to see it, it's clearly the hit of the show. But the demo, while striking and definitely worth the time to see, could have used less talk and longer, or more, actual demonstrating. I really wanted to see it a second time, but knowing that the two actual demo selections lasted, at best, 10 minutes, I decided against it.
