Well, would you take a look at that. Right on cue, Dolby and SIM2 are collaboratively showcasing a 46-inch 1080p display built around the former firm's high dynamic range technology. The HDR-enabled LCD HDTV boasts 1,836 LED-based backlight units (designed / developed by SIM2), a full 1,920 x 1,080 resolution, brightness level greater than 4,000 cd/m2, an "infinite" contrast ratio, 16-bits of luminance and a Xilinx Virtex field programmable gate arrays (FPGAs) chipset. Additionally, the prototype employs a design created by Giorgio Revoldini, and while we can't imagine hearing of a release date anytime soon, the two firms aren't wasting any time putting the new set on a world tour to presumably wow onlookers. Hey SED, you taking notes here?

Just when you thought high dynamic range was slipping into the background once more, we've received new information that the technology is not only alive and well behind certain closed doors, but that it will be making its debut relatively soon. Reportedly, SIM2 has teamed up with Dolby to create a prototype display incorporating Dolby's HDR technologies. More specifically, the unit will be an HDR-enabled LCD using Dolby's LED local dimming technology, which should provide "dramatically enhanced contrast." Regrettably, we're not told anything beyond that -- resolution, design, inputs, etc. all remain a mystery -- but you can go on and mark Q1 2008 down as the period in which we should see the first elusive prototype. 'Course, the key word there is "should."

Much like SED, OLED and Laser TV technologies, high dynamic range has been lingering in the background for what seems like ages, but a new writeup over at Sound & Vision is bringing it back (at least partially) into the spotlight. Reportedly, Dolby -- which purchased BrightSide Technologies earlier this year -- will be making some sort of announcement about the tech at CES, but judging by current estimates, we won't see sets based on HDR for "two or three years." For those who've forgotten what the fuss is all about, high dynamic range is purportedly able to offer whites whiter than white and blacks darker than anything else out there, but such luxuries aren't apt to come cheap for early adopters. Dolby refused to cough up an estimated price range for the first retail models, but who knows, maybe we'll learn a touch more about all of this in just a few weeks.

BrightSide Technologies blew observers away with demos of its high dynamic range (HDR) HDTVs back in 2005 but we haven't heard much about them since then. Today the technology might have come a step closer to commercial release as the company has reach an agreement to be acquired by Dolby for $28 million. BrightSide's Extreme Dynamic Range displays are capable of contrast ratios far beyond todays LCDs, and a maximum brightness far better than even that 1,000,000:1 contrast ratio OLED we saw at CES. Still, just like OLED and SED this is another technology that promises to take HDTVs to a whole new level of realism but has more hurdles to jump before it hits the mass market. Here's hoping we see this on store shelves sooner, rather than later -- minus the enormous ugly bezel though, we have a reputation for style to keep up.
