braille display
<hardware> (Or "refreshable braille display", "refreshable
display") An electromechanical device that renders braille
with tiny, independently controlled pins used to represent the
state of dots in braille cells. Each pin, in its "on" state,
raises above the top of its hole in the screen; in its "off"
state, it drops below the top of its hole. Older systems used
tiny solenoids to control the state of the pins; modern
systems are piezoelectric.
Typical dimensions of a braille display are 1 line of 40
cells, each cell of two-by-eight dots.

Refreshable braille display
A refreshable braille display or braille terminal is an electro-mechanical device for displaying braille characters, usually by means of round-tipped pins raised through holes in a flat surface. Visually impaired computer users who cannot use a standard computer monitor can use it to read text output. Deafblind computer users may also use refreshable braille displays.
Speech synthesizers are also commonly used for the same task, and a blind user may switch between the two systems or use both at the same time depending on circumstances.
