[edit] Overview

From the E Ink web site.

Spectra works similiarly to dual pigment system, in that we apply a charge to our pigments, and to a top and bottom electrode to facilitate movement. However, Spectra is utilizing a microcup ink structure. The microcup technology came from SiPix.


By using electronic shelf labels (ESL) with E Ink's technology, retailers have the ability to change pricing strategies as needed in real time, allowing them to stay one step ahead of competitors while attracting consumers based on changing market conditions. Spectra allows retailers to elevate the impact of their ESLs, by adding color to logos and quickly directing consumers' attention to important information, such as product sales and promotions.
