Maybe the panel has a native 10,000:1 contrast ratio?

I wonder what the "bit depth expansion" entails?

Plugging the least significant bits with zeros?
Some kind of dynamic greyscale?
12 bit panel drivers?
Marketing gimmick?

Would be nice if it was something meaningful to picture quality and not just some fake-looking video processing mode that should be turned off.

It could be some sort of dithering to 12-bit effective range with 10-bit drivers, or maybe it could be 12-bit drivers. Or, it could be all hot air. We won't know until they start shipping and people get them in hand.

Okay, so now there are a bunch of LED-based TVs coming from numerous manufacturers. Sharp has some interesting goodies:

1. 65 inch!! (Yes!)
2. Thin bezel
3. RBG-LED (Same as Sony)

Interestingly, the press release seems to tout the local-dimming as a form of
power efficiency feature instead of black-level improvement.

Ah well, I just hope Sharp is able to re-establish themselves as a leader in LCD
technology. Seems Sony/Samsung have roared past them in recent years. Seems
like Sharp has become another Matrox.

They are referring to total backlight control not local dimming. They are touting a function which is similar to what they do with the current Aquos lines, with the backlight dimming according to the ambient light levels. If the room is bright the backlight is full on, if the room is dark you don't need to punch the picture through the ambient light, so the backlight dims.

It would be awesome if this was priced vagely reasonably (55" is just barely enough for me), but I fear they might have a drink of the silly juice before they set pricing.

There's going to be bugs in their first commercial implementation of it, so touting it as a purely picture quality improving feature is probably something they've made a corperate decision not to do. How well their LEDs are done compared to Samsung/Sony/LG/Philips remains to be seen.

Nice analogy.

I'm not sure this has local area dimming. I'd hope it does, but it's not mentioned anywhere.

probably not since it's so thin like the 9.9mm sony XV1 which uses LED BL illuminated from the side.

If it is actually edge lit, then it's highly unlikely to have area based dimming. It'd be a shame if it was, there's a significant performance hit compared to rear lit lighting.

According to the countdown it is still 2 months before worldwide release.
5147110/60/60/24=59.5 days or 31 October.
I hope they will later also have a 46", 52" is too big for me and too expensive.

RGB LED means 50% more colors over white led, I wonder if you can really see that?

The countdown is saying ~102,700 seconds for me. That's 1.2 days, ie. the start of CEDIA.

Considering BT.709 only covers about 40% of the visible spectrum, sure. However, if you plan on calibrating the set to the HDTV standards and not just cranking things up as far as they'll go then the extra gamut is not necessary whatsoever. Once we start getting some xvYCC material that will change, but that may be several years away.

Funny your counter is different from mine.
Different counter depending on IP number location?
so much for "released simultaneous worldwide"
the site also mentions Oct 2008.

Maybe it's based on your computer's clock?

I'm getting Oct 08 also. It's great that the LED LCD story doesn't end this year with XBR8 and there's still XS to look forward to later on. BUT, regardless of the specs Sharp is giving, it seems quite obvious this is not the stunning display that was shown at last year's IFA. Just compare the pictures and videos of the two. The prototype had almost OLED-like contrast from any angle while you can barely see what's on the XS' screen in the pictures taken from the side. XS looks like a regular LCD on every picture. Perhaps Sharp wants to dole out whatever improvements they've made in stages and it will be several years before they bring to market all of the prototype tech. Recall that the prototype was scheduled for release sometime in 2010.

It has local dimming! The pattern is shown in a brochure.
The XS1 has a seperately media-box. So you have only one HDMI-cable to the display. It´s an amazing display with the best bezel finish at the show (brushed metal - better than the cheap look from the 6500 EUR Sony X4500.) and a great picture performance!

The 42" is only a prototype. In the brochure you can only find the 52" and 65".

Sharp is known for releasing new models in the fall.

Sony and Samsung release at different times of the year, but tend to be pretty consistent. This makes it more fun for everyone, always something to look forward to.
