Solari di Udine SpA is an Italian company for public information displays, historically split-flap displays. The company was founded in a small town in northern Italy in 1725. It began working with designer Gino Valle after World War II.[1]
The company's split-flap displays, commonly with white numbers on black flaps, won the Compasso d'Oro award in 1956. In this year, Solari sold its first moving sign to Liege railway station in Belgium. There is no known record of surviving Solari split-flap displays, though hundreds have been replaced with more modern displays across the world.[1]
