Frequently Asked Questions

E-Ink screen is referred as “Electronic Paper Display.” It is a display technology that looks like paper with high visibility and contrast. It contains millions of black and white microcapsules and uses a positive or negative electric field to move them to the top. So they can form different texts and images visible to readers. E ink screen reflects the ambient light to viewer’s eyes to show better contrast in the sunlight. It doesn’t emit light or blue light.
Print Color ePaper, or E Ink Kaleido™, is one of E Ink Color Technologies. An E Ink Kaleido screen is based on a black&white E Ink screen, but it applies a Color Filter layer consisting of RGB regular pattern on the top. The new printed Color Filter Array (CFA) technology can reflect light in different colors.

Advanced Color ePaper (ACeP™) is a high quality, full-color reflective display. In the ACeP™ system, the ink consisting of colored pigments can produce full color at every pixel to achieve a full-color gamut. It doesn’t require a color filter array (CFA) as Kaleido does. However, ACeP™ can only support a low refresh rate currently. It is mainly used on digital signages, public information boards, menu boards and galleries.

New Kaleido, offically named as Kaleido Plus, is the latest version (3rd generation) of the Kaleido technology. It uses a CFA (Color Filter Array) in a different printing color pattern, balancing color and printing texture up to three times better than the previous version.

The updated Kaleido screen, Kaleido Plus, uses a different printing color pattern to balance color and printing texture. Its color performance is up to 3 times better than Kaleido. Besides, the new image rendering allows for crisper text. The new panel has an optimized color spectrum and minimized color blending from scattered light by using front lights and guides. The new Kaleido also increases the viewable angle by 60° to offer a 120° viewing angle. All these improvements contribute to a better color and reading experience with the 7.8″ Kaleido Plus.

Onyx BOOX Nova3 Color uses a 7.8inch new Kaleido (Kaleido Plus) screen.

Currently, E Ink only develops 7.8inch screens using the new Kaleido (Kaleido Plus) technology. And we’re the first brand that applies it on a digital writing tablet with Wacom layer that offers versatile reading and multitasking features.

The resolution of colors is 100 dpi, while the resolution of black and white content is 300 dpi.
BOOX Nova3 Color can display 4,096 (16*16*16) different hues in total.
In the previous color epaper generation, color is much more washed-out. Based on the latest Kaleido Plus screen, we improve color brightness and saturation especially for the color E Ink display. Also, we initially create the Display Control mode for color eReaders and digital color tablets. Users can control the color contrast, saturation and brightness separately to reach a favorable display effect.
Nova3 Color uses an electronic epaper screen that doesn’t emit light or blue light. Also, Nova3 Color uses photobiological safety lights as front lights placed in front of the E Ink screen and under the bezel. They light up the screen but don’t shoot into users’ eyes directly. When users use Nova3 Color for a long time for reading or note-taking, they won’t feel much eye strain as they do with LED/LCD screens.

Nova3 Color can last for 40 days on standby mode with neither internet and WIFI connection nor front lights.
