The display was announced at SID 2014, which took place from June 1 to 6, 2014 at San Diego, U.S.

One of the two book-type displays can be folded in half like a book, while the other a three-fold display. The OLED displays are 5.9-inch when unfolded, with pixel count and resolution at 1,280 x 720 and 249 ppi respectively. The OLEDs were made using white light-emitting OLEDs and color filter.

The book-type and three-fold displays can be bent up to curvature radii of 2mm and 4mm, respectively. They can be bent more than 100,000 times, SEL said. For further reading please click here.
