    Abstract: An outward-folding display device includes two flat casings adapted to be connected to a flexible display, and two hinge units connected between the casings such that the casings are convertible between unfolded and folded positions. Each of the hinge units includes two rotatable drive shafts, and two compensation subunits each including a rotating plate that is co-rotatably connected to a respective one of the drive shafts, and a driven plate that is slidable relative to the rotating plate and that is connected to a respective one of the casings, such that during conversion of the casings, the driven plate and the respective one of the casings slide relative to the rotating plate to prevent the flexible display from being stretched and damaged.

    Abstract: A flexible electronic device includes a flexible display, a support structure and two hinge mechanisms. Each hinge mechanism includes a cam and first and second arm units. With the hinge mechanism having first and second cam follower protrusions of the first and second arm units which are moved from respective cavities of the cam and slide on respective peripheral cam surface sections of the cam during the pivoting of the first and second movable arms from an unfolded position to a folded position, a leeway is provided between the first and second movable arms for the flexible display to be bendably received therein.

    Abstract: A multi-linkage hinge includes a base bar, two friction bars, two synchronous rotation bars and two torsion plates. The base bar extends longitudinally to have two connecting ends and two middle pivot portions . Each friction bar has two link ends respectively coupled to the connecting end of the base bar and a middle portion of the respective torsion plate. The synchronous rotation bars are interposed between the friction bars, and each has two pivot ends respectively coupled to the middle pivot portion of the base bar and a driven end of the respective torsion plate. The torsion plates are turnable synchronously relative to the base bar between unfolded and folded positions. In the unfolded position, a bending space is formed between the torsion plates for receiving a bending portion of the display sheet.

    Abstract: An angularly positionable flexible display device includes a flexible display, a first substrate, a second substrate, and a positionable hinge mechanism which is disposed in a mounting space defined between the first and second substrates. In response to application of a manual force upon at least one of the first and second substrates, the first substrate is angularly displaceable relative to the second substrate through the positionable hinge mechanism to permit the flexible display to be bent with the angular displacement of the first and second substrates. Once the manual force is release, the first substrate is angularly positioned relative to the second substrate through frictional force provided by the positionable hinge mechanism.
