A split-flap display, or sometimes simply a flap display, is a digital electromechanical display device that presents changeable alphanumeric text, and occasionally fixed graphics. They were[when?] commonly used as public transport timetables in airports and railway stations.

They were often called Solari boards after the Italian display manufacturer Solari di Udine, or, in Central European countries, Pragotron after the Czech manufacturer.

Split-flap displays were once commonly used in consumer digital clocks known as flip clocks.
