Braille Display

An electromechanical device that displays braille characters using small pins that raise and lower dynamically, enabling blind users to read digital text through touch. Traditional braille displays present a single line of braille text (typically 14-80 characters) and are primarily used as output devices for screen readers. They differ from refreshable tactile displays in that braille displays present text characters in a linear format, while tactile displays present two-dimensional graphics across a larger pin array. Braille displays are essential assistive technology for deaf-blind users who cannot access audio-based screen readers, and are widely used in education and professional settings.
