E Ink Kaleido vs. New Kaleido Plus vs. ACeP: Color E Ink Comparison

Since E Ink’s color ePaper technology Kaleido hit the market last summer, iterations from Kaleido2, Kaleido2.5 to Kaleido3 have sprung up. Although the names are pretty confusing, one thing can be assured is the new Kaleido, Kaleido Plus, is the latest iteration officially announced by E Ink

From most consumers’ perspectives, the features and the differences of Kaleido iterations matter more than their names.

This article is breaking down the myths of Kaleido. Besides showing you the differences between Kaleido and the new Kaleido Plus, we also add E Ink Gallery, the Advanced Color ePaper (ACeP), into the comparison to give you a complete look into the color E Ink world.

What is Kaleido?

E Ink Kaleido™ is a print color ePaper using Color Filter Array (CFA) technology. It doesn’t contain any color microcapsules. Instead, it uses a color filter consisting of Red, Green and Blue (RGB) patterns on the top to reflect light in different colors.

Kaleido Plus is the latest iteration of Kaleido. 

Before Kaleido Plus was released, people had heard of some experimental and transitional versions. Compared to Kaleido Plus, they are ready for neither consumer electronics nor mass production

Currently, Kaleido Plus is only applied in 7.8inch E Ink devices like BOOX Nova3 Color.

E Ink Gallery, also named Advanced Color ePaper (ACeP), is a technology that uses color electronic ink microcapsules to show colorful images.

Compared to Kaleido, the Gallery can show a full-color gamut and is more vibrant and saturated. It’s often used in bus stops, outdoor signages, and other outdoor digital devices. 

However, it doesn’t support an acceptable refresh rate for reading books and taking notes. It can’t be applied to ebook readers and ePaper notepads.

Conclusion

As the latest color ePaper technology for E Ink readers, tablets, and cellphones, New Kaleido can show more saturated colors with less disrupting grids. It renders a display like a watercolor painting with pastel colors.

Although its ghosting characteristic is severer than the monochrome E Ink screen, we try to offer more systematic solutions to alleviate it. And we hope you can enjoy the color screen with our original algorithm and exclusive improvements.
