Many major smartphone manufacturers are investing in technology that will allow for flexible displays, as they work on the next generation of products.

Some of the UK's cutting edge research in this area is happening in Cambridge, also known as Silicon Fen.

The BBC's Katia Moskvitch went there to visit two groups working on different technologies that allow flexible displays.

Andrea Ferrari, Professor of Nanotechnology at Cambridge University, showed her around his Graphene Lab at the Engineering Department, while Michael Banach demonstrated Plastic Logic's approach to the issue.
