E Ink Launches E Ink Kaleido 3, the Next Generation of Print Color ePaper Technology

[TheLostSwede]

E Ink, the originator, pioneer, and global commercial leader in digital paper technology, today announced the launch of E Ink Kaleido 3. This new generation of E Ink Kaleido offers richer colors, along with 16 levels of grayscale and 4096 colors, perfect for displaying colorful images and information on eReaders and eNote devices. By optimizing the design of the ePaper module structure, E Ink Kaleido 3 has increased its color saturation by 30 percent compared to the previous generation, E Ink Kaleido Plus. E Ink Kaleido 3 is using E Ink's Print Color ePaper technology, where a color filter array (CFA) is used in conjunction with E Ink's Carta black and white ink film, creating a full color device for a more fully realized eBook shopping and reading experience.

In addition to improved color performance, Kaleido 3 uses E Ink ComfortGaze, a new front light technology designed by E Ink's Front Light Team. ComfortGaze has been engineered to reduce the amount of blue light reflected off the surface of the display, providing further comfort while reading. ComfortGaze has been engineered to reduce the amount of blue light reflected off the surface of the display, providing further comfort while reading with reduced Blue Light Ratio (BLR) and Blue Light Toxicity Factor (BLTF) by up to 60 percent and 24 percent respectively compared to the previous generation of front light design.




"The color eReader with E Ink Kaleido technology has received wide support and recognition from many customers since its release," said Johnson Lee, CEO of E Ink. "E Ink continues to innovate color ePaper, and with E Ink Kaleido 3, we've enhanced the vividness of the colors, improved the module design and created a healthier visual reading experience. We are excited to see this new technology roll out in customer products."

The E Ink Kaleido 3 module is available in various panel sizes, including 7.8-inch, 10.3-inch, and 13.3-inch. The responsiveness of the ink enables the module to play animations and videos, providing new options for digital reading and writing in educational and professional applications. The 13.3-inch E Ink Kaleido 3 ePaper can also be used as outdoor advertising signage.

I've been following color e-ink advancements for a while, hoping for some kind of breakthrough in the technology that would push it over the top and allow for it to really move forward.

Still looks pretty washed out to me, but a screen with a 4-week battery life readable in direct sunlight more than makes up for the compromises.

4-bit colour may not be glamorous but it gets the job done in 99% of situations.

My dream device (well, one of them) is a big (10 inches at least) Android e-ink tablet. Maybe it's time to look into it again.

e-ink and animations are horrible. Perhaps e-ink refresh rates have improved massively since my Kindle but even basic UI scrolling is a mess. Almost any web 2.0 content is a nope.

I need this for my he... comic book collection.

I don't need animations on it though. Mostly reading, but with the app support of Android.

I call bullshit.

Everyone knows that h.... comic books are black and white 99% of the time.

Seriously though, what e-ink needs most is good devices at good speeds. Remarkable 2 (https://remarkable.com/) looks decent, I might buy one to try it out, but... I don't really need color for most of my real world uses.

Knock down the price by another $100 or $200 however, and suddenly we're now talking. The only pragmatic e-ink screens were 6-inch class e-inks (which shared e-ink screens with Amazon's Kindle, lowering the price significantly). All other e-ink screens were such low-production runs that they never were offered at a reasonable price.

A good A4 + Letter compromise size (8.5" x 11.75" fits all European A4 and USA Letter-sized documents) at full resolution would be amazing for an e-reader. A shame that this larger size just was never popular.

Aah, the spicy comic book collection.

It's Masters of the Universe.

They didn't do themselves any favours with the image choice, the colour improved a fair bit but it looks oversharpened on all the fruits.

Saturation looks much better to the previous display, but the color PPI looks to still be around 100 PPI, which likely indicates they are still using a Micro-Cup.

IMO, only reason to go with a E INK rather than DES display atm is for the larger array of screen sizes offered by E INK over DES

One of my favorite YouTubers messed around with such a device...

Yeah, it's definitely not unusable, but navigating the UI on Android is full of movement and animation. You simply can't use Android without sliding menus, scrolling pages, fade ins/outs.

Perhaps a custom theme/skin/UI designed with static elements specifically for e-ink would look less like a blurry 1fps mess on a panel with 750ms response times

Since 2010, I am convinced that foldable E-Inks are the future of reading and writing, but technology is still not there yet (getting closer with each year!). Last year, I tried Onyx Boox Nova 3 Color, but very bad ghosting and short battery life were dissuasive for me. I currently use Kindle 2021 model. The browser is horrible, but reading e-books is an ok experience. I would like slightly larger screen, higher resolution and colors (some books and comics have colorful illustrations). Kindle's battery lasts weeks. Boox Nova 3 Color's battery lasts days at best (I used it from 100 to 70% in one sitting).

This would be great to use for reading training/technical PDF's as they do use colour illustrations.

I hope they come out with one in the size of an A4 paper and not insanely priced.

Yeah, this is why e-ink doesn't really work as a display for a highly-interactive device. It's perfect for ebooks, and currently not much else.

Argh, TPU's auto-embed ruining it.

4mins 20s into the video is where he loads youtube, and a couple of minutes later he highlights serious issues just scrolling a page of text on wikipedia.
