We have already seen a couple of flexible smartphones launched from both Samsung and LG, and now a number of companies have shown off foldable OLED displays.
Nokia and SEL (Semiconductor Energy Laboratory) have shown off some two foldable OLED prototypes, both display measure 5.9 inches and come with a HD resolution of 1280 x 720 pixels, have a look at the video below.
The display is made by forming a release layer, sealing layer and color filter layer in this order on a glass substrate. And a release layer, sealing layer, TFT layer and OLED layer are formed in this order on another glass substrate. Then, the color filter layer and OLED layer are attached to each other, and the glass substrates are peeled off and replaced with flexible substrates.
These new displays were announced at SID 2014, and one of the displays is designed to be like a book, and it can be folded in half. The other display is a ‘three fold’ display which can be folded in three.
They certainly look interesting from the photos and the videos, as yet there are no details on which devices may use these new foldable displays first.
