New flexible smartphone can be rolled up onto your wrist

A US-based company has developed a smartphone prototype with a full-colour flexible display which can be rolled up conveniently on to the wrist.

To receive a call, it can either be used as a speaker or removed and straightened into a traditional phone.

At the end of the call, you may bend it back onto your wrist and continue with your run, the company said.

FlexPhone, developed by US-based Royole Corporation, can also function as a fitness tracker where it can monitor many physical parameters including heart rate, steps taken, and distance travelled.

At around six millimetre thick and 100 gram in weight, it is light enough to go with you when you exercise or for a night on the town.

Additionally, with both display and circuitry being flexible, the FlexPhone is able to handle drops and bumps with less chance of breaking.

The phone features 3G connectivity, is SIM card compatible, and runs off of an Android OS.

This flexible smartphone prototype has been named as Innovation Awards Honouree at the CES trade show in Las Vegas.

"We are thrilled to be recognised as a CES 2017 Innovation Awards Honouree for the product," said Bill Liu, Founder, and CEO of Royole.
