Nokia surprise everyone by unveiling its new folding OLED display
Nokia’s Semiconductor Energy Laboratory has unveiled a new kind of OLED display that can be folded like a book while in use, similar to technology that Apple is thought to be exploring for future iPhones and the long-rumored “iWatch.”
Collaborating with Semiconductor Energy Laboratory (SEL) Co Ltd and Advanced Film Device (AFD) Inc (a subsidiary of SEL), Nokia is currently working on a display that can be folded in two or three while displaying videos.
Nokia demoed its new folding display technology at an academic conference in San Diego last week. At the Society for Information Display (SID) 2014 conference, Nokia showed off two types of high-resolution OLED folding displays -
- First display can be folded twice – which Nokia calls a ‘book type’ display
- The second is a ‘three-fold’ display – which can be folded three times
The flexible OLED displays features -
- Uses white OLEDs with color filters (WOLED-CF) design
- To produce the display, SEL deposited the organic and color filters layers on a glass substrate, which is later peeled off and replaced with a flexible substrate
- Screens sizes are 5.9-inches
- Pixel count of 249 ppi
- Resolution of 1280 x 720 pixels
- Folded to an impressive 2mm radius
- Displays also max-out at 100,000 folds
