E Ink Kaleido 3 color e-paper display increases color saturation by 30 percent, reduces blue light reflections

E Ink’s latest Kaleido 3 color ePaper display increases color saturation by 30 percent compared to the earlier Kaleido Plus color e-paper display, integrates E Ink ComfortGaze new front light technology engineered to reduce the amount of blue light reflected off the surface of the display, in order to provide further comfort while reading.

The new modules based on Kaleido 3 will be offered in various panel sizes including 7.8-inch, 10.3-inch, and 13.3-inch, support up to 16 levels of grayscale and 4096 colors, and target eReaders and eNote devices.

E-Ink Kaleido 3

E Ink explains that Kaleido 3 relies on the company’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”.  As I understand it that part has not changed, and it’s just the same as with Kaleido Plus which was introduced in early 2021, after the first 4096-color Kaleido e-paper display weres introduced in 2020, and found in products such as Onyx Boox Poke2 Color eReader.

ComfortGaze is said to reduce Blue Light Ratio (BLR) and Blue Light Toxicity Factor (BLTF) by up to 60 percent and 24 percent respectively compared to the front light design used in devices based on Kaleido Plus color e-paper displays. There were no specifics with regards to refresh rates, but E Ink claims the responsiveness of the ink enables the module to play animations and videos,  noting that the 13.3-inch E Ink Kaleido 3 ePaper display can also be used as outdoor advertising signage.

I was unable to find extra details about Kaleido 3 on the company’s website, so for now, all the public information is provided via the press release. More details should become available at Touch Taiwan 2022 on April 27-29, 2022 where E Ink will demonstrate the new technology in booth #M802 on the 4th floor of Taipei Nangang Exhibition Center.
