It appears that Nokia has unveiled its new folding display technology at the Society for Information Display 2014 conference, having on display two types of high-resolution OLED folding displays.
Though the technology is at its early stages, Nokia cloud be hinting at potential new handsets featuring the flexible displays in the near future. Other manufacturers, such as LG and its Flex handset, have also entered the market with such handsets bearing flexible displays, therefore Nokia might be heading on the right path with these new displays.
The first display is said to have the ability to be folded twice, having Nokia calling it a ‘book type’ display, while the second display has the ability to be folded three times. Both screen are said to measure in at 5.9-inches, having a pixel per inch count of 249 and bearing a resolution of 1280 x 720.
Although the display can be folded, that does not mean it can be folded indefinitely. Nokia has stated that the maximum folds before the display breaks is currently set at 100,000 folds. In addition, the displays can be folded to a 2 mm radius, meaning the screen can not quite touch, but it is impressively close.
In terms of production, the displays are said to be made by forming release, colour filter, TFT and OLED layers on a glass substrate, having the colour filter and OLED layers attached to each other and finally having the glass layer replaced with flexible substrates.
Nokia has not officially stated their intentions with the given flexible displays, but given that the company is a handset and tablet manufacturer, one would guess that new flexible display Lumias could surface in the future.
