Print Color ePaper- E Ink Kaleido™
Contents |
[edit] Description
from the E Ink web site:
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.
Applications: eReader, eNote, eSchoolbag, Smartphones and more.
[edit] Features
- display 100dpi in color, but since the monochrome pixels underlying it are approximately 300dpi, the effect is close to a 300dpi color display, since the bright/dark edge of any area is at 300dpi.
- Combines latest E Ink Carta HD screen with a color filter layer that allows the displays to show up to 4096 different colors. An E Ink Carta HD screen can display 16 shades of gray at 300 pixels per inch. But each color pixel will actually be made up of multiple grayscale pixels — which means that when you’re viewing color graphics you’ll probably be limited to 100 or maybe 212 pixels per inch.
- Units that can make notes with a stylus will also have a WACOM active digitizer layer.
- Kaleido display size was only 6" (demo eBook) and 5.84" (Hisense phone).
