You only need to charge this E Ink digital poster once a year

E Ink has collaborated with PocketBook and Sharp to create a new low-power digital poster that displays images and artwork on a vivid color electronic paper screen. The InkPoster pairs E Ink’s Spectra 6 screen technology with Wi-Fi and Bluetooth, allowing artwork to be regularly changed and uploaded. And thanks to a large battery, it only needs to be charged about once a year.

The InkPoster will be available in three sizes. The smallest model has a 13.3-inch screen with a resolution of 1200 x 1600 and a 14,000mAh battery, while the largest option measures 31.5 inches with a 2560 x 1440 resolution, giving it a slightly lower PPI in exchange for a bigger 20,000mAh battery. There’s also an in-between 28.5-inch, 2160 x 3060 version with a 20,000mAh battery that incorporates Sharp’s IGZO technology for faster screen refreshes. Pricing is expected to be around $599 for the 13.3-inch InkPoster, $1,700 for the 31.5-inch, and $2,400 for the 28.5-inch.
