Nokia unveils new folding OLED display as rumors say similar tech headed for Apple's 'iWatch'

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."

The Finnish communications giant demonstrated two foldable, 5.9-inch OLED panels at the annual Display Week conference in San Diego earlier this month, according to Nikkei Tech. The panels were jointly developed by Nokia SEL and Japanese subsidiary Advanced Film Device.

One of the panels can be folded down the middle, while the other can be folded in two places much like a pamphlet. Both 1,280-pixel-by-720-pixel displays can continue display video while folded and are manufactured using a special technique that sandwiches the color filter, TFT, and OLED layers between a sealer and a flexible substrate.

While neither panel can be folded completely like a piece of paper, the fold radius is impressively small and each can be folded and unfolded more than 100,000 times. The single-fold display can be bent to 2 millimeters, while the dual-fold panel can withstand a 4 millimeter curvature.

Despite publicly panning OLED technology in the past, Apple is rumored to have changed its tune when it comes to the so-called "iWatch." Recent reports have indicated that Apple may be planning to utilize a flexible, curved OLED display in the new wearable that would allow for a more sleek, form-fitted design than competing smart watches.

Though concept devices featuring curved or folded designs have existed for more than a decade, the only such products to make their debut have been mobile phones and televisions sporting slightly curved displays. Apple's ample engineering resources and massive war chest put the company in a unique position to fully realize the potential of OLED displays to enable totally new device designs.

Apple has also been seen taking a keen interest in foldable OLED displays for phones, applying for a number of related patents. One such patent covers iPhones with interactive, wrap-around displays, for example, while another deals with using flexible OLEDs to create a "pressable" display.

This gives the rumors more credence and if this is apart of the iWatch to give it more visible space then Cue was right in his assertion of great products in the pipeline. It would make all other smart watches look like baby toys. I wonder if this tech also makes the screen more durable from shock/drops/etc. or is it just more durable at the fold point(s).

can't see this happening on an iWatch. using sapphire over the display will force them to go with a fixed display. touch over a bending display will be an awkward user experience. and electronic components won't be bendable so it will remain rigid.

Still does nothing as far as convincing me to wear a watch or band. I consider my wrists permanently watch-free.

Two things.

 

One, the Apple patent/rumor-mill speaks of "wearable devices" of which a wrist-watch is just one incarnation of such a device.

 

Two, what if we've all glommed on to the idea that "iWatch" means "wrist-watch" when it means "self watch"? That is, a categorization of devices that watch personal biometrics - of which a wrist-watch is just one incarnation of such a device. "iWatch" becomes a marketing name for a group of devices, not just one.

Does it annoy everyone else that every new product release is touted as a competitor for an unreleased Apple device? There isn't an iWatch. There isn't an Apple TV 4. When there is, Then they can be a competitor. Jeez...
