Foldable smartphones, tablets get closer to reality

Tablets that collapse into phones. Smartphones that fold up like wallets. Those are coming and a Japanese company has the goods to prove it.  

At a recent event in Japan, Semiconductor Energy Laboratory (SEL), demonstrated a display that can be folded in three.  

 It’s not hard to see how this kind of technology could cause a sea change in device development. Products will expand and collapse at will. Open a device as a tablet at a coffee shop then fold it into a smartphone on your way out the door.
