"The technology, similar to that found in the Kindle Colorsoft e-reader, uses a six-color ink system to create the illusion of millions of tones. More importantly, using e-ink technology allows the frame to finally go cordless. That makes it ideal for hanging in your home in places where a corded display may look bad, like a living room wall, stairwell, or anywhere else a cord would ruin the aesthetic."
"In addition, Aura added a front light to the frame, taking a cue from the Kindle Paperwhite. This helps improve the contrast, notes Eric Jensen, Aura co-founder and CTO. "It's a very subtle light compared to an LCD. It's maybe a sixth of the brightness of an LCD," he told TechCrunch in an interview. "People often don't even notice it has a light until they're in a dark room and it turns off," Jensen adds."
Aura's Ink frame features a 13-inch color e-paper display that uses Spectra 6 six-color ink technology to simulate millions of tones. The e-ink panel enables cordless operation and claims up to three months of battery life between recharges, enabling unobtrusive wall placement where cords would be unsightly. Aura added a front light to improve contrast while keeping overall brightness much lower than LCDs. The company implemented a proprietary error-diffusion dithering algorithm to blend limited ink colors and improve perceived saturation and detail. The frame aims to better display smartphone photos with improved contrast and color fidelity.
