Trivision
A trivision is a billboard face of turning three-sided slats that shows three ads in turn.
OAAA defines a trivision as a unit with a slatted face. The slats turn so three different ads take turns.
Each slat has three sides. The ad is printed in strips that are cut to fit the slats.
Each advertiser gets a share of the time, a bit like spots on a digital face. The motors and slats are moving parts, so they need more upkeep than a flat face.
