Split-flap display

commonly used as public transport timetables in airports and railway stations.

Their output can be changed by reprogramming instead of replacement of physical parts but they suffer from lower readability.

Advantages to these displays include: The Massachusetts Bay Transportation Authority has designed the new LED replacements for its aging Solari boards at North Station and South Station to emit an electronically generated flapping noise to cue passengers to train boarding updates.

Early seasons of the game show Family Feud used a split flap display as part of the game board (subsequent seasons used more modern digital displays, and eventually simply used a large digital flat screen monitor).

[citation needed] In Italy, split-flap displays have also been occasionally used as destination signs for transit vehicles; there was also a brief vogue for them in the United Kingdom in the mid 1980s.
