Multi-particle ink system, Advanced Color ePaper (E Ink ACeP™). The ACeP™ ink platform achieves a full color gamut, including all eight primary colors, by using colored ink particles. The ink can be incorporated into either microcapsule or Microcup® structures. Color is achieved by having all the colored particles in every pixel, removing the need for a color filter array (CFA). ACeP™ maintains ultra-low power and paper-like readability under all lighting conditions of regular E Ink ePaper.
