E Ink introduced the world's first full-color e-paper

E Ink, which invented the modern type of electronic paper, introduced the Advanced Color ePaper (ACeP) technology - a high-quality full-color display on electronic ink (32,000 colors).

For the first time, electronic paper is capable of displaying an arbitrary color for each pixel without applying an array of color filters . Until now, nothing of the kind existed, and E Ink rightly assumes that color electronic paper with ultra-low power consumption will make a real revolution in the market of gadgets, portable and wearable electronics, displays, etc.

ACeP e-paper displays a full color gamut, including all eight primary colors, only using multi-colored pigments.

Principle of operation

The display contains one layer of electrophoretic liquid, which is controlled by a voltage comparable to the voltage of a thin-film transistor in commercial TFT LCD displays.



The liquid is collected either in microcapsules or in Microcup structures. The variety of colors is achieved by the concentration of multi-colored pigments in each pixel - this is in contrast to the standard arrays of color filters, where the pixel consists of a group of multi-colored neighboring elements. This eliminates the problem of light attenuation , which can be very significant.

Like ordinary electronic paper, full-color ACeP retains ultra-low power consumption and readability like regular paper in any lighting conditions.

Unlike other attempts to make multi-color e-paper, which uses complex multi-layered structures, E Ink engineers managed to develop a simple single-layer display structure. The secret is in the patented technologies for controlling multicolored pigments in this layer.
