Term: Braille Display
A Braille display is a tactile device consisting of a row of special "soft"cells. A soft cell has 6 or 8 pins made of metal or nylon; the pins are controlled electronically and move up and down to display characters as they appear on the display of a computer or Braille note taker. A number of cells are placed next to each other to form a soft or refreshable Braille line. As the pins of each cell pop up and down, they form a line of Braille text that can be read by touch.
