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.
Often used as a public transport timetable in airports or railway stations, as such they are often called Solari boards after Italian display manufacturer Solari di Udine, or in Central European countries they are called Pragotron after the Czech manufacturer.
Split-flap displays were once commonly used in consumer digital clocks known as flip clocks.
