E Ink announces new Kaleido Plus color displays with brighter colors and bigger screens

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.
