Braille displays, or braille terminals, braille displays, are electromechanical devices that can output in Braille. In general, the device performs dot matrix performance by punching holes on a flat surface. With the help of this device, blind users who cannot use a normal display device can also read text. In addition, there are also ways to use a screen reader and a speech synthesizer, and the visually impaired can choose a device convenient to them from two ways.
