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.
