Abstract
A flexible display device may include a flexible display screen, a rotating shaft, a resetting mechanism, and a positioning mechanism. The flexible display screen is wound on the rotating shaft. The resetting mechanism may be connected to the rotating shaft. The resetting mechanism may be operable to drive the rotating shaft to rotate to unfold the flexible display screen. The positioning mechanism may be configured to position the unfolded flexible display screen; and the resetting mechanism may be further operable to drive the rotating shaft to rotate in an opposite direction such that the flexible display in the unfolded state may be wound on the rotating shaft.
