Researchers have come across a method for producing a flexible braille display that uses about the same power as a cell phone. The display can be refreshed in about one second and could be used to indicate the amount of money left on a prepaid card, household appliances, or even an e-book. It uses a plastic film with organic transistors and plastic actuators that expand when triggered. So far it will display 24 characters but researchers hope to take this up to 576 in a few years. Look for this to be on the market in five or six years.
