Color E Ink displays extend the benefits of traditional e-paper—eye comfort, low power use—by adding color for diagrams, textbooks, comics, and signage. Researchers and manufacturers are improving refresh rates and color saturation, making them relevant beyond e-readers.
What Is a Color E Ink Display?
A color E Ink display uses filters or pigment layers to add red, green, and blue elements to the standard black-and-white microcapsules.
- Kaleido 3: adds color filter over grayscale E Ink.
- Gallery 3: uses four-pigment system for richer tones.
- Typical DPI: 150–300 for color, lower than monochrome equivalents.
Energy consumption: ~70–80% lower than LCD in static mode (Society for Information Display, 2023).

How Do Color E Ink Screens Compare to Monochrome?
Color screens sacrifice some sharpness but add functionality.
- Advantages of color E Ink: diagrams, highlights in study notes, magazine-like layouts.
- Advantages of monochrome: sharper text, higher contrast, longer battery.
Use cases: monochrome better for novels; color better for comics, textbooks, and planners.
