Abstract: An example of a foldable display device includes a display panel having a first area, a second area, and a foldable area therebetween; a first support plate supporting the first area of the display panel; a second support plate supporting the second area of the display panel; a central support disposed under the foldable area of the display panel and configured to move vertically; a first peripheral support slidable while supporting the first support plate; a second peripheral support slidable while supporting the second support plate; and a hinge body disposed under the central support. The central support ascends toward the display panel during an unfolding operation and descends toward the hinge body during an in-folding operation. The first peripheral support and the second peripheral support move toward the central support during the unfolding operation, and move away from the central support during the in-folding operation.

Abstract: A foldable display apparatus includes a mid-layer having a hinge region; a panel on the mid-layer; a pair of set frames under the mid-layer; and a hinge portion connected to the pair of set frames, and moving as the panel is folded or unfolded. Since a sliding section of the panel in the hinge region is compensated for during the folding and unfolding of the panel, the size of a bezel that would otherwise accommodate a sliding section can be reduced.

Abstract: A foldable display device can include first and second casings for respectively supporting a first area and a second area of a display panel. The first and second casings are coupled to a hinge. The foldable display device can further include a slidable support which has a first end movably connected to the first casing, and a second end fixed to the second casing, and a slidable plate attached to the display panel and movably connected to the second casing. The slidable support supports a foldable area of the display panel between the first area and the second area of the display panel during an unfolding operation and an out-folding operation. Thus, the foldable display device performs both the in-folding operation and the out-folding operation.
