  • Patent number: 10701822
    Abstract: An electronic device includes a base cover, a cover plate which is slidable relative to the base cover among a closed position, an open position, and a transition position, and a slide positioning mechanism which is configured for positioning the cover plate relative to the base cover, and which has first and second magnetically attractive units. When the cover plate is in a selected one of the closed and open positions, a magnetically attractive force is generated to position the cover plate in the selected one of the closed and open positions. When the cover plate is in the transition position, a magnetically repulsive force is generated to facilitate movement of the cover plate away from the transition position.

  • Patent number: 10591959
    Abstract: A bendable displaying apparatus of the present disclosure includes two housings, a supporting device, and a bendable display. The supporting device is fastened to the two housings and is arranged between the two housings. The supporting device includes a retainer, two supporting units, a first supporting plate, and two second supporting plates. The bendable display is disposed on the two housings, the first supporting plate, and the two second supporting plates. When the two housings are moved to stack with each other, the two housings drive the two supporting units to move the two second supporting plates along a direction away from each other and drives the retainer to downwardly move the first supporting plate, so that the two second supporting plates and the first supporting plate jointly form a space that provides the bendable display to deform therein.

  • Patent number: 10352354
    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.
