E Ink today announced Advanced Color ePaper (ACeP), which is a full-color reflective display. E Ink says this is the first time an electrophoretic display can produce color in every pixel without the use of a color filter array. The ACeP includes all eight primary colors using colored pigments in a single layer of fluid; each pixel is capable of displaying all eight colors. The fluid is controlled using voltages that work with traditional TFT backplanes. E Ink says its ACeP maintains the same paper-like readability and low-power features of its monochrome ePaper screens. E Ink has been able to create ACeP screens up to 20 inches with resolutions at 1600 by 2500 pixels. For now, E Ink says the ACeP display technology will target signage and other use cases. The company didn't say if it might create versions of the ACeP for mobile devices, such as cell phones. Powering displays requires a lot of energy, so battery-based mobile devices could benefit from a color ePaper screen.
