This article was translated from Dutch with the help of AI. Read the original.

Digital photo frames have been around for a while, but they are often glossy screens that need to be connected to a power supply. eInk has been promising a solution to both problems for years. InkPoster has announced three digital photo frames based on this technology.

InkPoster is a collaboration between three companies: PocketBook, Sharp and E Ink. InkPoster is available in three sizes: 13.3 inches, 28.5 inches and 31.5 inches.

You can display thousands of carefully selected artworks on the screen, but it can also serve as a digital photo frame. The latter is of course the most interesting option for us as photographers.

The InkPoster can display 60,000 colours. That may sound like a lot, but most screens can show millions of colours. There is a good chance that your photos will look disappointing on this screen.

The 13.3-inch and 31.5-inch models use E Ink's Spectra 6 screen technology, while the 28.5-inch version uses Sharp's IGZO technology. Both screen types are unaffected by reflections and mimic the appearance of paper.

The InkPoster is energy-efficient and only needs to be charged once a year. So there is no fixed power cable. You can charge the screen with a USB-C cable.

The 28.5-inch model has the highest resolution at 2,160 x 3,060 pixels, while the 31.5-inch model offers a resolution of 2,560 x 1,440 pixels.

The 28.5-inch model also stands out with a faster refresh rate thanks to Sharp's IGZO technology. In principle, this is not directly interesting for anyone who wants to use the screen as a digital photo frame.

All models come with a white mount and a black aluminium frame. The 13.3-inch model has a 4:3 aspect ratio, the 28.5-inch version has a 1.41:1 (A2) aspect ratio, and the 31.5-inch version offers a 16:9 aspect ratio.

The InkPoster supports both Wi-Fi and Bluetooth and can be connected to a smartphone using a special app. This allows users to browse available artworks or upload their own photos.
