Abstract
Disclosed is a Braille display with protection against the ingress of contaminants. In one embodiment, contaminant protection is provided by a flexible film that is secured beneath the Braille dots of the display. This film both secures the dots and prevents contaminants from coming into contact with pin actuators within the display housing. In another embodiment, ingress protection is provided by air pressure supplied to a plenum located at the base of the dot pins.
