Abstract
A Braille display system and a method for operating a refreshable Braille displayis provided. A string of characters is assigned to a drive signal for specifying the activation or deactivation of a tuple of dots which are raised through holes in a touch and sense surface of the Braille displayupon activation and which are retracted upon deactivation. The Braille displayis driven by a drive signal which is configured to activate and/or to deactivate the tuple of dots so as to generate a dynamic tactile display of said string of characters. The time dependent characteristic of activation and/or deactivation of the tuple of dots is defined by the string of characters.
