Earlier this year, E Ink unveiled large displays using Kaleido color e-ink, which are designed for digital signage. Now, the manufacturer has announced the 75-inch Spectra 6 display based on Kaleido, aimed at use in stores, restaurants, transport and other public places.

Despite significant advances in color e-paper over the years, the content displayed on these displays still cannot compare to what can be seen on LCD or OLED displays. Spectra technology was developed for high-end digital signage, the latest iteration of which is designed to “deliver full color for improved marketing and advertising effectiveness” and to reduce the environmental impact of digital signage. Depending on the panel size, Spectra 6 offers up to 200 ppi, a 30:1 contrast ratio, and an operating temperature range of 0 to 50 °C.
E Ink confirmed that the new 75-inch Spectra display can operate in the specified temperature range, but did not reveal other details, including the resolution and contrast of the panel. The manufacturer only promises rich and vibrant colors. The display uses Ripple technology, which expands the panel’s capabilities in terms of color reproduction and smoothness of content refresh.
Like other similar displays, the new product consumes energy only when updating the image on the screen and has no backlight, relying on ambient lighting to add saturation to the image. Support for E Ink Sparkle technology has been implemented, which creates a partial blinking effect, helping the sign attract the attention of potential buyers.
«“Our new 75-inch Spectra 6 display marks a major milestone in E Ink’s commitment to creating cutting-edge, eco-friendly digital signage. By combining rich, full-color e-paper with exceptional energy efficiency, we provide advertisers, brands, and retailers with an innovative way to engage customers while reducing their environmental impact,” E Ink said in a statement.
Finished Spectra 6 display samples will be delivered to E Ink partners in the fourth quarter of this year. More information about the technical characteristics of the new product will probably become known then.
