E Ink Gallery Plus is geared towards indoor commercial signage and public information displays

BILLERICA, Mass.--E Ink, the originator, pioneer, and global commercial leader in digital paper technology, today announced the launch of the latest generation of their Advanced Color ePaper (ACeP) platform, E Ink Gallery Plus. This next generation, full color ePaper module, has a color gamut ideally reaching 60,000, an improvement over the earlier generations. E Ink Gallery Plus targets indoor commercial signage for retail, restaurants, transportation and public information displays. The 28-inch and 25.3-inch displays are being used in the Smart Display Metro Digital Train of Taipei Metro.

E Ink Gallery Plus is using E Ink ACeP™, a full color electronic ink system with four color pigments: cyan, magenta, yellow, and white, used to achieve a full color gamut at each pixel. The contrast ratio is improved by 40%, from 10 to 14, providing a more impactful visual experience. The look and feel of the new generation is similar to color prints, with the benefit of digital changes that allow for instant updates to match with promotion and communication needs. E Ink Gallery Plus will be available in various sizes for customers, including 13.3-inch, 25.3-inch, and 28-inch.

"E Ink has been investing considerable R&D resources in ePaper film and modules, as well as in color drivers, hardware and software, enabling continuous refinement and innovative breakthroughs in ePaper technology," said the CEO of E Ink, Johnson Lee. “The new generation of E Ink Gallery Plus significantly improves the contrast ratio of our full color ePaper, and can help customers’ make their advertisements more eye-catching.”

E Ink will cooperate with ecosystem partners to jointly introduce E Ink Gallery Plus into the digital signage market. The goal is to replace single-use printed posters in commercial advertising and public information displays and reduce the impact on the environment. E Ink Gallery Plus features low-power consumption, can be driven from solar power and is eye-friendly, attributes that are beneficial in the development of sustainable smart cities.

Note: Gamut is a range of colors within the color spectrum that the human eye can identify, and it is also a concept of color space.

what about pixel density?

Only about 70 dpi to 150 dpi is needed for signage. But I don't see anything about pixel density or resolution or response time (speed irrelevant for posters).

The Cyan Yellow Magenta must be in layers rather than in side by side of R G B or
R G
G B
Matrix schemes.
They'd need clear liquid and C, Y or M balls that are to sides for clear, then front and/or back for colour.
The regular eink uses a milky liquid and you see an negative image on the rear as the white & balk balls swap. Early eink had only black balls.

In theory layered C Y M is more than 6x brighter than than R G B. 19th C colour slides used R G B starch dots and were very dim compared to later C Y M layered coloured negatives and the cunning colour reversed slides.

I'm surprised that they aren't also using black.

I'm suspecting the white is actually a white & black layer at the bottom.

I look forward to a proper explanation of the technology used.

As far I understand from what is posted on Eink's site, ACeP uses 4 colours of pigment so no colour filter is needed. I haven't found any information on the refresh rate for the Plus displays but hopefully, the refresh speed has been improved to the point where you read books or take notes on it. I've attached an image what the ACeP Microcup is supposed to look like.

I think I see. With no white pixels on it's sort of like printing on black paper.

Different than CMYK ink printing where K is the black that's mixed in with the CMY. As I remember you can't use 100% of all three of the CMY inks because it makes a soggy mess. And even if you could you still don't get black.

It adds almost nothing extra to what we know.

Sorry - I would be fine if this message is deleted by an admin.

The tracker seemed to have been an Engadget mistake, gone when last checked.
