Marquee[edit]

Main article: Marquee (sign)

A letter board or letter sign, also known as marquee, is a customizable form of signage which employs individually movable letters of the alphabet. They are used by, e.g., movie theaters to list the current roster of films, churches to display the titles of sermons, and other buildings, people, and institutions whose signs are required to change on a regular basis.

Aid tool[edit]

Letter board also may refer to aid tool, used by people with disabilities, to communicate with others, by pointing letters on board with written on it letters (whole alphabet), numbers and other essential signs, even whole frequently used words.[1] This may be used by people with amyotrophic lateral sclerosis, for instance.
