E Ink Color Technologies

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.

Not yet commercially available, the initial target application for ACeP™ will be for digital signage applications.

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

E Ink is now offering smaller displays using the ACeP technology with a limited, but super saturated, color palette. These displays are geared toward Smart Retail applications; specifically for end-cap, store aisle and window promotions. Retailers are able to update store signage consistently with their shelf tags, and offer the most up-to-date pricing and promotion to customers. The high resolution, reflective display allows images, QR and barcodes, and text, with future sizes planned from small to mid-size, enabling detailed promotional information.

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.

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, faster and brighter. 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 video. 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 Triton Displays are ideal for a variety of dynamic content applications such as indoor Signage.

E Ink Spectra™

E Ink Spectra is the first three pigment electronic ink offered in mass production and is available for retail and electronic shelf tag labels. EPDs using Spectra offer the same high-contrast, sunlight readable, low-power performance attributes of our other display types - now with a pop of color. The first generation of Spectra features black, white and red or yellow pigments, and we expect to release additional colors in the future.

E Ink Spectra has been optimized for the electronic shelf label and point-of-purchase signage markets.

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.
