Abstract
A foldable display device has a flexible display panel, a support module, and at least one positioning module. The support module has a middle platform and a pair of side platforms. The positioning module has a pair of positioning gears respectively fixed to the intermediate platform on a pair of gear axes parallel to each other and a pair of planetary gears respectively fixed to the pair of side platforms on a pair of gear axes parallel to each other. The pair of planetary gears are respectively engaged with the pair of positioning gears to respectively move around the pair of positioning gears along a pair of motion paths, so that the pair of side platforms are switched between a flattened state and a folded state with respect to the intermediate platform to flatten or bend the flexible display panel.
