Abstract
A foldable display device includes a first casing and a second casing supporting a first area and a second area of a display panel, respectively, a support disposed between the first casing and the second casing, supporting the display panel based on the folding direction of the foldable display device, and including a support body which ascends toward the display panel during the out-folding operation, and descends toward a bottom face of the hinge cover during the in-folding operation.
Claims21
A foldable display device, comprising:
- a display panel having a first area, a second area, and a foldable area between the first area and the second area;
- a first casing supporting the first area of the display panel;
- a second casing supporting the second area of the display panel and being spaced from the first casing;
- a support disposed between the first casing and the second casing to support the display panel;
- and
- a hinge cover accommodating the support,
- wherein the support includes a support body that is configured to ascend toward the display panel during an out-folding operation of the foldable display device, and descend toward a bottom face of the hinge cover during an in-folding operation of the foldable display device,
- wherein the foldable display device further comprises a support plate, the support plate including a foldable portion overlapping the foldable area of the display panel and configured to fold in response to the out-folding operation and in response to the in-folding operation,
- wherein the foldable portion includes a plurality of holes, and
- wherein an upper portion of the support body has a top face convexly curved toward the display panel with a fixed curvature and has a greater width than that of a lower portion of the support body including a rack gear.

- a display panel;
- a first casing supporting a first area of the display panel;
- a second casing accommodating at least one slidable plate and including at least one sliding-guiding groove to guide a slide movement of the at least one slidable plate in a first direction, wherein the at least one slidable plate supports a second area of the display panel spaced from the first area of the display panel;
- a support disposed between the first casing and the second casing to support the display panel and including a support body configured to ascend in a second direction toward the display panel during an out-folding operation of the foldable display device, and descend in the second direction away from the display panel during an in-folding operation of the foldable display, the second direction being substantially perpendicular to the first direction;
- and
- a support plate including a foldable portion overlapping the foldable area of the display panel and configured to fold in response to the out-folding operation and in response to the in-folding operation,
- wherein the foldable portion includes a plurality of holes, and
- wherein an upper portion of the support body has a top face convexly curved toward the display panel with a fixed curvature and has a greater width than that of a lower portion of the support body including a rack gear.
