E Ink announced a new version of their Kaleido color displays. Named Kaleido Plus, the new screens have the same color reproduction as the first generation but bring improvements in screen assembly and the front light that improve the overall picture and color saturation.

E Ink is known for its monochromatic paper-like displays in eReaders like the Amazon Kindle and Rakuten Kobo. However, the company introduced a color display, dubbed Kaleido, last year. Yesterday, E Ink Holdings announced an update to their color display with some minor improvements.

The new Kaleido Plus color displays offer the same 16 levels of grayscale and 4096 colors as the first Kaleido screens, but E Ink has changed the screen assembly process. Kaleido Plus displays have slight tweaks to the printing pattern and bring the color layer closer to the ink layer for a brighter overall picture. Text rendering has also been improved. 

A new front light design helps to focus light to make images look more saturated. E Ink claims the new screens triple the color gamut of the first generation Kaleido displays when the front light is turned on.

Kaleido Plus displays are also light thanks to a new printed Color Filter Array technology that removes the need for glass. Additionally, E Ink will manufacture up to 7.8-inch Kaleido Plus screens. The first color E Ink displays were limited to 6 inches. 

Kaleido Plus screens will make their debut in a few devices, notably PocketBook’s InkPad Color eReader and Onyx’s BOOX Nova3 Color eReader. 

What do you think of the new Kaleido Plus displays from E Ink? Let us know in the comments.

I've been a computer geek my entire life. After graduating college with a degree in Mathematics, I worked in finance and banking a few years before taking a job as a database administrator. I started working with Notebookcheck in October of 2016 and have enjoyed writing news and reviews. I've also written for other outlets including UltrabookReview and GeeksWorldWide, focusing on consumer guidance and video gaming. My areas of interest include the business side of technology, retro gaming, Linux, and innovative gadgets. When I'm not writing on electronics or tinkering with a device, I'm either outside with my family, enjoying a decade-old video game, or playing drums or piano.
