Advanced Color ePaper (ACeP)- E Ink Gallery™

Advanced Color ePaper (ACeP™) is a high quality, full color reflective display. In the ACeP™ system, the ink can produce full color at every pixel, without the use of a color filter array (CFA).

ACeP™ achieves a full color gamut, including all eight primary colors, using only colored pigments. The display utilizes a single layer of electrophoretic fluid which is controlled using voltages compatible with commercial TFT backplanes. The fluid can be incorporated into either microcapsule or Microcup® structures. The richness of the colors is achieved by having all the colored pigments in every picture element (pixel) rather than the side-by-side pixel colors achieved with a CFA. This eliminates the light attenuation, which can be quite significant. ACeP™ maintains the ultra-low-power and paper-like readability under all lighting conditions of regular E Ink ePaper.

Advanced Color ePaper (ACeP)- E Ink Gallery™ Palette

E Ink Gallery Palette uses the same full-color ePaper film as our ACeP product but is driven by simpler electronics to support cost sensitive applications that do not require the full-color performance of ACeP. Gallery Palette supports the seven most frequently used colors in advertising and signage, namely: Black, White, Red, Yellow, Blue, Green and Orange. Gallery Palette is geared toward applications where power autonomy is an essential requirement but only need a limited color range. Our customers are using Gallery Palette in areas such as smart digital badges, movable advertisement, indoor signage and lots more.

Print Color ePaper- E Ink Kaleido™

E Ink Kaleido™ displays offer 16 levels of grayscale and are capable of displaying 4096 colors, enable ultra low power and high mobility devices with a paper-like experience, ideal for image-rich information applications such as charts, graphs, maps, photos, comics and advertising. And just like E Ink's monochrome ePaper products, Kaleido’s crisp text and detailed color graphics are fully viewable in direct sunlight, and have the same low power attributes.

An E Ink Kaleido™ Module is comprised of a TFT backplane, Ink layer, Color Filter layer and Protective Sheet.

E Ink Kaleido™ utilizes a new printed Color Filter Array (CFA) technology in conjunction with E Ink’s second generation Carta ink, which is faster and brighter than previous generations. The new printing process alleviates the need for a glass-based CFA, making the displays thinner and lighter than previous generations, while simultaneously having higher optical quality. This allows eReader companies to combine the power of traditional black and white displays with color for a more fully realized eBook shopping experience. In addition, E Ink’s faster ink enables quicker updates for animations and page turns. With this new color technology, E Ink’s eNote product lines are now able to introduce writing tablets with color highlighters, pens and markers, giving new options for education and professional devices.

E Ink Kaleido™ Plus (New Kaleido)

In early 2021 E Ink released a new generation in the Kaleido family, named E Ink Kaleido™ Plus. In this new version, we’ve made adjustments to the printed CFA, to allow for a better color balance, and printing texture, and we’ve brought the CFA closer to the ink, to reduce light scattering. New image rendering algorithms allow for crisper text. In addition, we have made adjustments to the light guides, allowing for better optimization of the LED color spectrum to minimize color blending.

E Ink Prism™

E Ink Prism™ will transform the way spaces and surroundings are experienced. Manufacturers and designers will now have the ability to integrate innovative films with architectural products to dynamically change colors, patterns, and habitats. E Ink Prism utilizes E Ink’s bistable ink technology in a film that can transform architectural materials into dynamic, one of a kind experiences and designs. It is visually similar to paint because it uses the same pigments found in the printing industry. But unlike traditional paint E Ink Prism can change the color of a wall, ceiling panel, or entire room instantly, at the flip of a switch.

It doesn’t stop at color. Programmable patterns and shapes can be integrated to create designs or function. Doors can indicate if a conference room is occupied, wall designs can respond to noise, temperature, or motion in the room. Whatever the idea, the opportunities are endless and only limited by a designer’s imagination.
