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.
Claims20
A flexible display device, comprising:
- a flexible display screen;
- a rotating shaft, the flexible display screen being wound on the rotating shaft;
- a resetting mechanism, being connected to the rotating shaft and being operable to drive the rotating shaft to rotate to unfold the flexible display screen;
- and
- a positioning mechanism, being configured to position the unfolded flexible display screen and drive the rotating shaft to rotate in an opposite direction such that the flexible display screen in the unfolded state is wound on the rotating shaft.
A portable electronic apparatus, comprising:
- a housing;
- a mainboard disposed within the housing;
- a rotating shaft pivotably mounted in the housing;
- a flexible display screen wound on the rotating shaft and connected to the mainboard;
- a resetting mechanism, being connected to the rotating shaft and being operable to drive the rotating shaft to rotate to unfold the flexible display screen;
- and
- a positioning mechanism, being configured to position the unfolded flexible display screen and drive the rotating shaft to rotate in an opposite direction such that the flexible display screen in the unfolded state is wound on the rotating shaft.
A driving mechanism for a flexible display screen, comprising:
- a rotating shaft with first and second caps engaged with two opposite ends of the rotating shaft to seal two opposite openings of the rotating shaft;
- a reset device configured to drive the rotating shaft to rotate to unfold the flexible display screen, the reset device comprising a connecting shaft and a roll-up spring, the connecting shaft configured to extend through the first cap and fixed on one corresponding end of the rotating shaft, the roll-up spring being received in the one corresponding end of the rotating shaft, one end of the roll-up spring being embedded in a free end of the connecting shaft, and the other end of the roll-up spring fixed on the rotating shaft;
- and
- a fixing device fixed on the first cap and configured to fix the unfolded flexible display screen and drive the rotating shaft to rotate in an opposite direction such that the flexible display screen in the unfolded state is wound on the rotating shaft.
