Abstract:
Disclosed is a Braille display device. The device supports an array of individual Braille cells with corresponding tactile pins. The pins can be selectively lifted by way of reeds to generate Braille characters that can be felt by the user. The Braille characters can correspond to visible characters, such as characters on a computer screen. The display is refreshable to allow for the sequential display of lines, paragraphs, or pages. In accordance with the disclosure, the Braille cells are constructed in a manner that minimizes manufacturing costs and that also permits the size of the display to be greatly reduced.
