A vane display is a type of 7-segment display. Unlike LED or vacuum fluorescent displays, vane displays consist of seven physical panels, typically painted white but sometimes in colors like fluorescent yellow or green. To show a segment as "off," the panel rotates so its painted side faces away, making it invisible. When "on," the painted side rotates forward to be visible.

Vane displays operate similarly to flip-disc displays, using electromagnets to move segments. In models where rapid changes aren't necessary, electric motors may rotate the panels instead. These displays are often found in game scoreboards and sports stadiums. A major advantage of vane displays is that they retain the last shown information even if power is lost. However, like flip-disc displays, they can be noisy if multiple segments change at once.

Today, vane displays are rare and have largely been replaced by LED displays, which offer superior visibility, especially at night.
