  • Patent number: 4836784
    Abstract: The invention relates to a device for displaying information on a reading unit for the blind. Instead of character fields arranged with certain spacings apart from one another for displaying Braille characters, the reading table is occupied by a dense matrix of character elements (4) with uniform line and column spacings. In the totality of character elements, certain character fields (6) are provided which serve for displaying the Braille characters. These are surrounded by other character elements which are not set in the displaying of Braille text, so that the Braille characters have the required spacing apart from one another. The whole reserve of character elements (4) is used for reproducing large-area graphics, large symbols, tables or the like. With a certain arrangement, described in detail, of the character elements, all of the information displayable on a viewing screen can be reproduced on the reading table, with the exception of reverse-brightness information and that displayed in colors.
