Hewlett-Packard and DreamWorks Animation have announced a new display technology, which is capable of displaying one billion colors. In a unique, two-year collaboration, the two companies have developed the “HP DreamColor” display. According to the companies, their new display will help solve a longstanding problem for digital artists, who often are forced to choose between consistent color accuracy and the affordability of the products they use.

One billion colors sounds truly impressive is, in fact, a significant boost from today’s widely used 24-bit color monitors, which are capable of displaying 16.7 million colors per pixel. The yet unreleased display will be the first to offer a true 30-bit color technology, incorporated in an LED-backlit LCD. According to HP, this combination guarantees to provide accurate, consistent and predictable color at all stages of the production process. "For decades, storytellers have struggled to manage color in an accurate and consistent manner," said Jeffrey Katzenberg, Chief Executive Officer and Director, DreamWorks Animation. "Quite simply, when we make a movie about a big, green ogre, our concern is that our ogre is the same color of green throughout the film. HP has truly changed the game with its new display, giving DreamWorks Animation full visual fidelity across the board for the first time."

The announcement regarding the new display was made at the recent National Association of Broadcasters Conference in Las Vegas. The companies also revealed that the upcoming display, which will become available for purchase sometime this summer, will cost much less than today’s high-end studio-quality LCD displays. This product was specially designed for the broadcast, film/video post-production, animation, and graphic arts fields, where it is crucial to obtain rich and consistent colors – e.g. darker blacks and true whites. "In the digital world, the media and entertainment industry oftentimes sets the pace for technology innovation," said Todd Bradley, Executive Vice President of the Personal Systems Group at HP. "The HP DreamColor display is a disruptive technology inspired by users, like DreamWorks Animation, that challenge HP to deliver exciting innovations that truly impact our customers' businesses."

The new technology is not limited to displays – HP and DreamWorks have developed a whole family of “DreamColor” products, including printers. These products will all come integrated with a special graphics card from AMD\ATI, which supports 30-bit color displays. According to HP, we should expect no less than pictures “jumping off the screen”. "HP has delivered a breakthrough technology that will show immediate results," said Crawford Del Prete, Executive Vice President at Global Research, IDC. "The HP DreamColor display is an important innovation that represents a significant collaboration between HP and a core partner. This technology will have broad appeal, allowing customers to deliver results never before possible without very high-end systems."

Some, however, doubt that the new technology will deliver a dramatic improvement in performance. Chris Chinnock, President of the research firm “Insight Media”, is one of those who are skeptical about HP’s claims. He says that while the 30-bit resolution will allow for better gradation between the color levels, the technology will not be able to increase the color gamut of a display. "It will make the displays much more accurate in being able to display colors and grayscale properly," said Chinnock. "Whether the colors look more vibrant and saturated will depend more on the backlight technology HP uses.” He also added that since most of today’s media content is generated for 24-bit quality, it is inevitable that the DreamColor technology be applied to source devices as well.

TFOT has previously covered several innovative display technologies including Aquavision’s 57-inch waterproof LCD television, which was recently showcased at the ISE show in Amsterdam, Sony’s “XEL-1” – the first commercial OLED TV to go on sale, and our special coverage of the displays presented at this year’s CeBIT fair in Hannover, Germany.

How Can We Tell?   (05/10/08 - 21:01 - by Dennis McClain)
A 24 bit video system can display 16.7 million colors. A 30 bit, about
a billion. The human visual system can discern about 4.5 million. The
present 24 bit systems are about 4 times more than we can see. Claims
of consistency, accuracy and such would require instrumentation to
prove, as we'd never see it, either in production or in
broadcast/display. If perhaps my training in neurophysiology is
wanting in this respect, I'd appreciate knowing how claims contrary to
the 4.5 Mcolor limit have been tested and supported, as the studies
haven't found their way to the regular biopsychology literature.

" The human visual system can discern about 4.5 million."

Can you
point to the experimental documentation for the above claim? In
particular how the number was arrived at?
simpler explanation   (05/11/08 - 5:17 - by JSH)
"How can we tell"
The article states that an increase in bits
provides an improvement in colour gradation - this is correct. The
initial reply to this shows a mediocre understanding of computer
graphics systems related to human visual acuity.
Take an existing 24
bit monitor, create screen-sized image with a horizontal green
gradient from low intensity to full intensity and fill the screen with
the image. Vertical bands of differing intensity will be completely
apparent to your visual system (an artifact of the number of bits per
component).
Regardless of the "number" of colours that 2^24 or 2^30
gives you remember that this is a representation of a small gamut -
other colours do exist outside of this rough quantisation.
Correct grammar?   (05/11/08 - 8:24 - by Raven...)
In the article, it says "Quite simply, when we make a movie about a
big, green ogre, our concern is that our ogre is the same color of
green throughout the film. HP has truly changed the game with its new
display, giving DreamWorks Animation full visual fidelity across the
board for the first time." From what I remember in art school, there
is only one color green, and many, many shades of green. Maybe we
should wait until the company learns how to read, BEFORE we trust them
on a project that shows more colors than the eye can discern.
Hardly new   (05/11/08 - 13:52 - by RFC3251)
Lots of systems already use 10-bit (and even 12- and 14-bit) colour
(usually processed at 16, for practical reasons). This isn't new.
What's new is if they manage to bring it to the mainstream market. And
hopefully make LCDs where the colour is accurate from *any* angle.
It's useless to have 1024 intermediate tones if the colour changes by
10% as I move my head up or down.

P.S. - Pretty much anything you
lear in an art school about colour is "subjective", to put it politely
(i.e., wrong).
