Abstract: The present disclosure provides a folding display device including a flexible display panel; a first case positioned at a periphery of the display panel; a mid-frame positioned adjacent to the display panel and extending co-planar with the display panel; a plurality of holes extending through the mid-frame at a central region of the mid-frame; a second case positioned adjacent to the mid-frame extending co-planar with the mid-frame; and a third case positioned adjacent to the second case and configured to support the second case. The second case has a hinge part overlapping the plurality of holes in the mid-frame. The holes in the mid-frame and a connecting member holding the holes together in the mid-frame provides elasticity, expandability, and pliability to the folding display device. The connecting member also provides durability so that the folded portion endures the numerous folding and unfolding activities by a user of the display device.

Abstract: A foldable display is disclosed. The foldable display includes a lower plate having a folding region abutted by unfolding regions. The foldable display includes a display panel on the lower plate which includes LED arrays so as to display images on all of the folding region and the unfolding regions. The lower plate includes first connection holes and second connection holes through which the display panel is connected to a printed circuit board on the lower plate. A hinge is coupled to the lower plate and includes hinge bodies and hinge links coupled together and configured to rotate such that the foldable display is manipulatable between a folded state and an unfolded state through a predetermined rotation path.

Abstract: Disclosed are a folding device of a foldable display and a display device having the same. The folding device is rotatable sequentially or in stages through a plurality of unit hinges rotated relative to one another about multiple axes. Therefore, the folding device is applicable to both an inner folding type and an outer folding type, and the respective unit hinges are rotated by gear motions and may thus be stably rotated and assure reliability.
