Yes. Samsung first put its plain LED backlit 40-inch set on European market and now they plan to release 4 new models in US that not only extend the color gamut thanks to LED light, but also drastically increase the contrast thanks to local dimming.
This new local dimming sounds very much like the Brightside technology, and if you read the article referenced in this and another thread you might notice that 2006-2007 is the timeframe that the LED technology should "catch up".
Exactly. If one reads the referenced article, it should be apparent that many things about Brightside set are consistent with what we already know about Samsung's 81 series. This is why I strongly suspect Samsung licensed the technology from Brightside. Also, one of the "Asian manufacturers" could be LG which appears to have licensed the same technology as well. (Brightside wanted to license their technology to as many manufacturers as possible). I was quite surprised to learn LG.Phillips plans to release its own locally dimmed set at 1Million:1 contrast ratio
in Q2 of this year. That set alone probably deserves its own thread. Sharp has been showing its own 1Million:1 prototype for two years implying this technology was years away from reaching the market. It looks like Samsung and LG have figured out a way to bring this innovation to market early (perhaps because they use different technology than Sharp). Here's a pic of that LG.Phillips' set:
Haitz's law, is referenced in the article and is kind of like Moore's law for LEDs.
When that article was written (Oct 2005) LED's had efficacies around 30lm/W. A year later the efficacies have grown to around 100lm/W and the pace of this growth seems to accelerate still. What this means, of course, is that power consumption will not be a problem for locally dimmed sets. The manufacturers will be able to increase resolution of LED backlight without worrying about power, cooling or fans. They will also be able to increase the brightness of these sets well beyond 500cd/m2. And all of it before color-filterless technology shows up in LCDs which will further diminish power consumption levels of LCDs. And speaking of LED backlight, here's how locally dimmed backlight looks like:http://blog.hometheatermag.com/cedia...1506planarlcd/
Planar showed off a prototype LCD panel that is the coolest thing I've seen so far at the show. It's a normal LCD panel with 800 individual LED backlights that are on an active matrix back plane. What that means is that each LED is individually addressable depending on the video signal. Want a section of the screen to be dark? Dim the backlight in that area. The result is a fantastic legitimate contrast ratio, and actual blacks (cause the light is off). The picture above is just what the backlight is doing with the LCD off. It's at least a year away from a real product, but it looks amazing.
And here's how a locally dimmed set (in this case from Planar which, incidentally, looks just like Brightside set with Planar logo on it) looks in action vs. a conventional lcd monitor:
(Obviously when viewed on regular monitor, black and white levels of any high-contrast set will appear crushed.)
