The world's first portable electronic Braille display is small enough to fit in a pocket and can even be rolled up like a newspaper. The display consists of a sheet of tiny plastic paddles that bend in response to a voltage. It is designed to connect to a cell phone or laptop, and could also replace the liquid crystal screen of an ordinary personal digital assistant (P.D.A.).
