A foldable display apparatus, comprising:
- a housing frame including a first frame and a second frame;
- a hinge assembly coupled to the first frame and the second frame to implement a folding and unfolding movement of the first frame and the second frame;
- and
- a display panel disposed on the first frame and the second frame,
- wherein the hinge assembly includes:
- a plurality of hinge arms each coupled to one of the first frame and the second frame;
- a hinge housing disposed below the plurality of hinge arms and accommodating the plurality of hinge arms;
- and
- an arm cover disposed above the plurality of hinge arms and fastened with the hinge housing, the arm cover including a plurality of guide units each having a shape recessed from a lower surface of the arm cover in an upward direction and respectively corresponding to the plurality of hinge arms to accommodate at least a part of a corresponding one of the hinge arms in the recessed shape and contact an upper surface of the corresponding one of the hinge arms,
- wherein a lower surface of each of the guide units has an arc shape and faces toward the hinge housing, the arc shape being convex in a downward direction,
- wherein both ends of each of the hinge arms are configured to rotate upwardly in a folding movement, such that the hinge assembly is configured to fold the display panel inwardly so that the display panel is positioned in an interior of the foldable display apparatus in a folded state, and
- wherein each of the guide units of the arm cover includes a step portion to stop the corresponding one of the hinge arms from rotating to fold the display panel outwardly.
A foldable display apparatus, comprising:
- a first frame and a second frame;
- a display panel connected to the first frame and the second frame;
- and
- a hinge assembly rotatably connecting the first frame and the second frame to fold or unfold the display panel, the hinge assembly including:
- a first hinge arm coupled to the first frame;
- a second hinge arm coupled to the second frame;
- a hinge housing below and accommodating the first hinge arm and the second hinge arm;
- and
- an arm cover above the first hinge arm and the second hinge arm and fastened to the hinge housing, the arm cover including a first recessed guide corresponding to the first hinge arm and a second recessed guide corresponding to the second hinge arm,
- wherein each of the first recessed guide and the second recessed guide has a shape recessed from a lower surface of the arm cover in an upward direction to accommodate at least a part of a corresponding one of the first and second hinge arms in the recessed shape and contact an upper surface of the corresponding one of the first and second hinge arms,
- wherein a lower surface of each of the first recessed guide and the second recessed guide has an arc shape and faces toward the hinge housing, the arc shape being convex in a downward direction,
- wherein both ends of each of the first and second hinge arms are configured to rotate upwardly in a folding movement, such that the hinge assembly is configured to fold the display panel inwardly so that the display panel is positioned in an interior of the foldable display apparatus in a folded state, and
- wherein each of the first recessed guide and the second recessed guide of the arm cover includes a step portion to stop the corresponding one of the first and second hinge arms from rotating to fold the display panel outwardly.
