Patent ID: 10901457

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.
