What is a split-flap display?
A split-flap display, also called a Solari board after the Italian maker Solari di Udine, is a board that shows text and numbers using small flaps that physically rotate into place. You know the sound: the clatter of an airport or train departure board updating.
Where you've seen them
Airports, train stations, stadiums and stock exchanges used split-flap boards for decades. Each character cell holds a stack of flaps; a small motor rotates the stack until the right letter or number faces forward.
Why they're loved
It's the motion and the sound. A split-flap board feels alive in a way a screen of static text never does, which is exactly why they've become a design icon in cafés, hotels, offices and homes.
Mechanical vs digital
Real mechanical boards (like Vestaboard or Oat Foundry) cost thousands and have thousands of moving parts. A digital split-flap display like Split-Flap TV recreates the same flipping motion on a TV you already own, from €19.99/month.
