It’s a breakthrough for E Ink, display advertising and, maybe someday, e-readers and digital photo frames. The new prototype display, which can be manufactured in an array of sizes, features a 20-inch, 2500 x 1600 resolution and is equally as power-efficient as the monochromatic display. E Ink Holding’s Head of Global marketing Giovanni Mancini said it can be powered with solar cells used in bus stop signage, for example. Some of the limitations center around the resolution and refresh rate. As of right now, the resolution is only 150 pixels per inch (ppi), which is about half the resolution of a typical 6-inch, monochromatic E ink display. It also takes about two seconds to fully resolve images, which is pretty slow when compared to today’s e-readers. The company is currently only focused on using the new color display for commercial signage.
