Typically saying "1 million to 1" means it's basically unmeasurable because the blackest blacks are essentially pitch black and the whitest whites are pure and pearly.
DLP LEDs are better because it reduces the colourwheel effect and they used three independent RGB LED arrays to provide the colour combinations. DLP technology is different to LCD, where Brightside corresponds types of colour that are deemed bright or not bright and then it lets the panel display the actual colour, whereas DLP adjusts each individual channel on a per-colour basis.
Using LEDs as a general backlight gives a better uniformity and power useage than CCFLs, but unless it's brightside it isnt really dynamic.
More indication of Brightside Technology being put to use in commercial products is found in this article on Samsung's plans for LED-backlit LCD's.
From the article:

100,000:1 contrast ratio through the use of "local dimming" LEDs -- a process whereby the backlighting is effectively shut off in dark areas to generate true black. Samsung plans to include these local dimming LEDs in their LCD TVs shipping this year. Great... prices and dates now please?
So it seems. Nice spot! Just for clarity, any man & his dog can do LED backlighting if they wish - it will become increasingly popular in notebooks moving forward (about time, since my own HP CCFL backlight is *constantly* on the blink).
However, Brightside have patents on any dynamic modulation of the backlight so it would seem that Samsung are licensing the tech. I will see if I can find out any more, though they're possibly as bound by commercial confidentiality agreements today as they were 18 months ago when we first published on this technology.
Press release, January 12; Emily Chuang, DigiTimes.com [Friday 12 January 2007]
Canon and Toshiba today announced an agreement by which Canon will purchase all of Toshiba's outstanding shares of SED, which was jointly established by both companies. On completion of the purchase, SED will become a wholly owned subsidiary of Canon, effective January 29, 2007.
The decision was reached following discussions between Canon and Toshiba based on the assumption of prolonged litigation pending against Canon in the United States with respect to SED (Surface-conduction Electron-emitter Display) technology, the companies explained.
As a result of the discussions, it was decided that Canon will carry out the SED panel business independently in order to facilitate the earliest possible launch of a commercial SED television business. SED TVs are to be introduced in Japan in the fourth quarter of 2007 as originally scheduled, although Canon will reassess its future mass-production plans for SED panels.
Mr Kazunori Fukuma, the current president of SED, appointed from Toshiba, will resign from Toshiba, after which he will be hired by Canon and continue to serve as SED president. Also, in accordance with the terms of a new agreement to be entered into between SED and Toshiba, plans call for Toshiba engineers on loan to SED, to continue their assignments for the transition period during which Canon will establish the SED panel business independently.
We already have a HDR display. And it`s cheat too.. ridiculously cheap. It`s called a CRT monitor. We should stop throwing money on useless products as long as we have cheap better ones.
For US$50,000 you could just go out and buy a brand new Marquee 9500LC CRT projector and get 30,000:1 contrast ratio and very little haloing (blooming) and have money left for a decent PC and home theatre surround sound system too.
Or you could go for a Barco Reality 909s and have the "best of the best, sir, with honours, sir" display but no money left out of US$50,000.
Either of the above 2 will do full 1920 x 1080p at up to 72Hz and in some cases 96Hz refresh rate and outlast ANY other display, CRT projection is a mature technology and proven to be reliable and very long lasting, I have a CRT projector (standard definition only unfortunately, Sony VPH1000QM) I bought used 14 years ago and it is still going and has NEVER had any repairs done and NEVER had the tubes replaced and I have put over 60,000 hours on it with it also having had 20,000 hours of use before I bought it making over 80,000 hours total.
Maybe so, but bear in mind that was the price back in 2005... You can expect to see this tech on consumer displays later this year, starting with the higher-end stuff I imagine but still in the US$4,000-10,000 range ie Premium but not Insane :)

Anybody seen any recent news on Toshiba SED? :D

Incidentally, Brightside was bought by Dolby so this tech is now known as Dolby Contrast
