Digital photo frames have long been a popular but often disappointing gift category — clunky cords, bright LED screens, and setup processes that frustrate less technical relatives. Aura, a company founded 10 years ago, has been waiting for color e-ink technology to mature before releasing its answer: the Aura Ink, a $499 frame that uses a six-color e-ink display and a custom dithering algorithm to make photos look like printed paper.
How Aura solved e-ink’s color problem
Color e-ink displays are rare — the Kindle Colorsoft is one of the few consumer devices using the technology — because the manufacturer, E Ink Corporation, currently produces only six colors: red, blue, green, yellow, white, and black. That palette is far from what a typical family photo or travel snapshot contains.

Aura’s co-founder and CTO Eric Jensen told TechCrunch that the company’s chief scientists spent years developing a dithering algorithm that breaks photos down into those six colors and arranges them in patterns the human eye reads as smooth gradients. “I’m learning color theory from our chief scientists, and as far as I understand it, there’s not a good definition for how many colors this represents well,” Jensen said. “It’s all sort of theoretical and comes down to how people perceive it.” The company tested the algorithm across different lighting conditions and with many viewers before bringing the frame to market.
Hands-on with the Aura Ink
TechCrunch tested both the 13.3-inch Ink frame and the company’s 12-inch LED Aspen frame for comparison. The Aspen, priced at $229, surprised with its anti-glare screen and paper-like matte finish that makes it look more premium than typical digital frames. But the Ink frame is the headline product.

Setting up the frame through the Aura app was straightforward — upload photos from a phone, web browser, email, iCloud, or Google Photos. The app also supports shared libraries, so family members can contribute photos that appear automatically on each other’s frames. By default, the Ink changes photos once per day, typically overnight. Manual changes take about a minute while the hardware runs the dithering process, during which the screen may appear to glitch.
When comparing the same travel photo on both frames, the color differences were noticeable but not necessarily worse. The limited palette gave images a slightly artistic, almost vintage feel. An analog film photographer who reviewed the frames noted the color inconsistencies, but casual users may not mind — or may even prefer the look.
Battery life and mounting
The Ink frame charges via USB-C and lasts about one month per charge. The display goes to sleep when the room is dark or empty to conserve power. Aura includes sturdy mounting hardware that makes it easy to hang and remove, though most users will only need to take it down for monthly charging.
Pricing and availability
The Aura Ink costs $499, making it significantly more expensive than the $229 Aspen LED frame. Whether the premium is worth it depends on how much the printed-photo aesthetic matters. For those who find LED screens intrusive in their home decor, the Ink frame offers a genuinely different alternative — one that looks less like a screen and more like a framed print.
Frequently Asked Questions
How does the Aura Ink frame display color with only six e-ink colors?
Aura developed a proprietary dithering algorithm that blends the six available e-ink colors (red, blue, green, yellow, white, and black) into patterns the human eye perceives as smooth color gradients, making photos look much closer to full-color prints.
How long does the Aura Ink battery last?
The frame lasts about one month on a single charge. It conserves battery by putting the display to sleep when no one is in the room or when the lights are off.
Can you share photos with family members using the Aura app?
Yes, the Aura app includes shared libraries so family members can upload photos that automatically appear on each other’s frames.
How does the Aura Ink compare to the Aura Aspen LED frame?
The Aspen ($229) uses an anti-glare LED screen with a paper-like matte display, while the Ink ($499) uses color e-ink for a printed-photo look. Colors on the Ink are less accurate but some users may prefer the artistic effect.
