English: The flip-disc display (or flip-dot display) is an electromechanical dot matrix display technology used for large outdoor signs, normally those that will be exposed to direct sunlight. Flip-disc technology has been used on buses across North America and Europe. It has also been used extensively on public information displays. A few game shows have also used flip-disc displays, most notably the Richard Dawson and Ray Combs versions of Family Feud. Some types of flip-dot displays are also combined with LED lighting of every flip-dot (DOT-LED-technology patented by Czech company BUSE Blansko as example).
