Full Color Eco ePaper
This is a cutting-edge solution designed by E Ink to match even the most demanding applications. The 13.3-inch Advanced Color ePaper (ACeP) marks the next step in ePaper evolution. It’s as colorful as LCD but comes in the form of ePaper.
This table presents the most important parameters of this innovative product.

This ePaper component is based on electrophoresis. Its cells are made of a mixture of oil and water, with pigment particles added to the mix. The mixture is set between two parallel electrodes. When we apply a positive or negative charge, the particles of the specified color move up or down to create the desired image. Since only black and white pigments were used originally, the solution allowed achieving greyscale images at most (1-, 2-, 4-bit).
Full color with Spectra & Triton
E Ink’s substitute for the first fully-colored display is Spectra, which is enriched with one additional pigment (yellow or red). Triton is the next one; it’s a traditional black and white display with an RGB-filter. Note that the saturation is limited, and the tones are slightly greyish.
Advanced Color ePaper
E Ink’s latest color ePaper technology is Advanced Color ePaper. In this technology, every pixel consists of four pigments forming the eight primary colors. The pigment particles differ in size, polarity, charge. We can move them by the changes in the voltage. It’s a high-quality, full-color ePaper solution.
Just like other ePaper solutions, Advanced Color ePaper offers advantages such as unlimited viewing angles, ultra-low power consumption, and excellent readability (even in direct sunlight). Note that ePaper requires an additional backlight (for example, LEDs).
The only drawback of Advanced Color ePaper? The time it takes to refresh content. Since the pigments are applied in layers, the final image is visible after c. 30 seconds, depending on the temperature.
You can also use the Advanced Color ePaper as an eye-catching architectural element. The inspiration here is another technology designed by E Ink called Prism. This technology is used, for example, in DAZZLE, an outdoor public artwork at the San Diego International Airport’s new Rental Car Center. It displays animation on over 2000 tiles.
