Hello all, this is my first post. I was reviewing this thread because this issue isn't as cut and dry as it should be. I was chatting with our Panasonic rep, who had just returned from a training session over the weekend. She showed me some paperwork she was given by her people.
Paraphrasing what she showed me:
The technology is a direct assault on 120 Hz. Yes, it's 480 Hz sub-field like we've discussed, but more importantly, it leverages the "vast processing power" of their processor. The processor is doing what they call, "Intelligent Frame Creation." hxxp://www.panasonic.com.my/web/Pid/5459
(I cannot post direct url, yet, sorry.
Their wording would lead one to believe it's somehow interpolating like the 120-Hz Samsungs and Sonys (Sharp 82 and Mitsubishi 144 models merely increasing their flicker rate - like projectors, and thus never looking as smooth), but they don't say this. The briefing she has says the processor analyzes frame by frame to maximize clarity... I looked at this quickly because it was lunch-time. I'll see if I can get her to get me a copy of this and I'll repost with their exact phrasing.
Anyway, just wanted to post this since I've been trying to peel more info out of her. I have to say, in side by side comparison, the th50pz800u looks much more natural to me than the ln52a750. The 750 made all the special effects segments of several of my favorite blu-rays look unbelievable (not in the good way). Our demo disk from Pan also has a few scrolling-marques which look much better on the 80 and 800s than my th50pz77u, which I still love!
