Nikkei Asian Review reported about a newly developed display panel by Japan Display (JDI), that can be opened and closed like a book and either show the same content on both sides (a film for instance) or entirely separate content, so people could write mail and surf the internet at the same time. This might be an ideal display for the smartphone industry, that strives to integrate bigger display sizes while maintaining portability.
Apparently, JDI is already working together with a big and global Chinese partner to release a smartphone with that display as early as next summer. Unfortunately we have no information on who that partner is as of yet. The display itself is based on LCD technology, features very slim 1 mm bezels around the screen and only has a 2 mm gap between the two sides of the display when opened.
