E Ink’s color display for retail and electronic shelf tag labels. Spectra displays offer black and white + 1 color, enabling retail signage the ability to highlight promotions or logos with a pop of color.
E Ink Spectra is the first three pigment electronic ink offered in mass production. EPDs using Spectra offer the same high-contrast, sunlight readable, low-power performance attributes of our other display types – now with a pop of color. The first generation of Spectra features black, white and red pigments, and we expect to release additional colors in the future.
Spectra works similarly to our other inks, 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, rather than the microcapsules we are known for.
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.
