# Braille displays

Display a graphical representation of images, icons, data, and more on a two-dimensional
braille display.

## Discussion

A refreshable braille display is a hardware device that shows rows of pins that can
raise and lower. People who are blind or deafblind use these devices to read digital
content through interaction with a screenreader, such as VoiceOver. For information
about connecting a braille display to an Apple device, read 
[Use a braille display
with VoiceOver on iPhone](https://support.apple.com/guide/iphone/use-a-braille-display-iph73b8c43/ios).

A two-dimensional refreshable braille display has a grid of evenly spaced pins that
you can use to represent images, charts, and other visual data to VoiceOver users
so they can experience your content through touch.
