Abstract: A foldable device includes a housing, a foldable display coupled to the housing, and a hinge mechanism at a bendable section of the foldable display. The hinge mechanism includes hinge track modules movably coupling adjacent pairs of hinge beams. Each hinge track module includes a track member coupled to one of the pair of hinge beams. The track member includes an arcuate slot. First and second hinge shaft members positioned at first and second sides of the track member are coupled to the other of the pair of hinge beams. The first and second hinge shaft members include a hinge shaft slidably coupled in the arcuate slot of the track member. Outer peripheral contours of the hinge shafts correspond to an inner peripheral contour of the arcuate slot to guide movement of the hinge shafts in the arcuate slot and maintain the foldable display within allowable bending limits.

Abstract: A flexible display that can be adjusted by an electromagnetic mechanism to remove a deformation is disclosed. The flexible display is attached to a body that is configurable in a folded configuration or an unfolded configuration by a hinge mechanism. When unfolded the flexible display includes a deformation (i.e., warp) in an area around the hinge mechanism. Accordingly, an electromagnet is included with the hinge mechanism to remove the deformation by attracting a magnetic element is disposed on a back surface of the flexible display.

Abstract: In a general aspect, a foldable display device may include processor, a memory, a first housing having a first end portion and a second end portion, a first length extending between the first end portion and the second end portion of the first housing, a second housing having a first end portion and a second end portion, a second length extending between the first end portion and the second end portion of the second housing, the second length being different than the first length, a flexible display disposed on the first housing and the second housing, and a hinge assembly disposed between the first housing and the second housing to rotate the first housing and the second toward each other. The hinge assembly may include a slider and plurality of gears. The slider and the plurality of gears operate to transfer a rotational movement into a translational movement of at least one of the first housing or the second housing.

Abstract: In a general aspect, a foldable display device may include a processor, a memory, a first housing having a first end portion and a second end portion, a first length extending between the first end portion and the second end portion of the first housing, a second housing having a first end portion and a second end portion, a second length extending between the first end portion and the second end portion of the second housing, the second length being different than the first length, a flexible display coupled to the first housing and the second housing, and a hinge assembly coupled to the first housing and the second housing for relative rotation of the first housing and the second housing. The hinge assembly may include a slider, a lever attached to the slider, a set of gears disposed on the slider, and a linkage member connecting the lever and the set of gears together. Upon the relative rotation occurring in a first direction by the second housing, the set of gears rotates and causes the lever to move translationally move the first housing in a first linear direction, and upon the relative rotation occurring in a second direction by the second housing, the set of gears rotates and causes the lever to move translationally move in a second linear direction, the second linear direction being opposite to the first linear direction.
