HP has developed a new wearable E Ink display for the army that is flexible and solar-powered. It can be wrapped around a soldier's wrist, and could show maps or directions. The whole display is just 200 microns thick. HP plans to offer first prototypes in early 2011.
The E Ink displays will be manufactured using a roll-to-roll process. HP says it will work with a company called Phicot that it spun out recently to produce these displays.
