Nokia Shows Off Prototypes Of Foldable Displays For Smartphone

It has just been a year that the curved display featuring handsets like LG G Flex and Samsung Galaxy Round have made it to the market. Now mobile phone displays with more interesting features are currently said to be under developement. Although Samsung and LG have both been working on improving their curved OLED panels for a couple of months but it looks like even Nokia will join the league soon.

As of now, Nokia is talking about foldable displays and not curved ones. At the recent Society for Display Information conference held in in San Diego, the Finnish company demoed a couple of models. It worked with a Semiconductor Energy Laboratory to create two 5.9-inch panels, each designed to be folded in a specific way.

More specifically, model number one can be folded into two -- like a book -- while the other can withstand being folded in three. They are 5.9-inch OLED panels when unfolded. Their pixel count and resolution are 1,280 x 720 and 249ppi, respectively. They were realized by using the "WTC" structure, which combines white light-emitting OLEDs and color filter.

By optimizing the screens for specific folding patterns like this, 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.

However, there is no information as to when the company will start using the latest foldable panels in the smartphones.
