CASINGS OR CONSTRUCTIONAL DETAILS OF ELECTRIC APPARATUS; MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS ## Abstract A foldable display apparatus includes a display panel having a light-emitting element disposed thereon, a cover window disposed on top of the display panel, a bottom plate disposed beneath the display panel, a bellows for supporting at least a portion of the bottom plate, a first support coupled with one end of the bellows, and an edge coupled with the other end of the bellows. ## Claims ### Claim 1 A foldable display apparatus comprising: a display panel; a cover window disposed over the display panel; a bottom plate disposed beneath the display panel; a bellows for supporting at least a portion of the bottom plate; a first support coupled with a first end of the bellows; and an edge coupled with a second end of the bellows, wherein a panel through-hole for sliding the display panel, the cover window, and the bottom plate therethrough is defined in one face of the edge. ### Claim 2 (depends on 1) The foldable display apparatus of claim 1, wherein the display panel has a light-emitting element disposed thereon. ### Claim 3 (depends on 1) The foldable display apparatus of claim 1, wherein the bellows has a characteristic capable of being compressed or tensioned by an external force and maintaining its state. ### Claim 4 (depends on 1) The foldable display apparatus of claim 1, wherein the bellows is disposed on each of a front face with a display area and a rear face. ### Claim 5 (depends on 1) The foldable display apparatus of claim 1, wherein the edge repeats moving closer to and further from the first support when a display area of the display panel is reduced and expanded. ### Claim 6 (depends on 1) The foldable display apparatus of claim 1, further comprising: a second support disposed between the first support and the edge. ### Claim 7 (depends on 6) The foldable display apparatus of claim 6, further comprising: an LM (linear motor) guide disposed inwardly of the second support; and a guide fastening portion movable with respect to the LM guide. ### Claim 8 (depends on 7) The foldable display apparatus of claim 7, further comprising: a bellows guide bar disposed inside the bellows and coupled to the guide fastening portion. ### Claim 9 (depends on 8) The foldable display apparatus of claim 8, wherein when the guide fastening portion moves along a driving shaft of the LM guide, the bellows guide bar coupled to the guide fastening portion moves along the driving shaft of the LM guide. ### Claim 10 (depends on 8) The foldable display apparatus of claim 8, wherein the LM guide is placed on an inner face of the second support, and the LM guide and the guide fastening portion are coupled to each other for driving. ### Claim 11 (depends on 1) The foldable display apparatus of claim 1, further comprising: a first accommodation portion defined beneath the first support and a second accommodation portion defined beneath the bellows; and a driver of the display panel disposed in at least one of the first accommodation portion and the second accommodation portion. ### Claim 12 (depends on 1) The foldable display apparatus of claim 1, wherein the panel through-hole is defined in each of at least two faces of the edge. ### Claim 13 (depends on 1) The foldable display apparatus of claim 1, wherein a hinge is disposed on a face of the display apparatus where the first support and the bellows are coupled to each other. ### Claim 14 A foldable display apparatus including a bottom plate, a display panel, and a cover window sequentially disposed, the foldable display apparatus comprising: a bellows for supporting at least a portion of the bottom plate; a first support for supporting another portion of the bottom plate; and an edge disposed at one end of the bottom plate, wherein a first end of the bellows is coupled to the first support and a second end of the bellows is coupled to the edge, and wherein a panel through-hole for sliding the display panel, the cover window, and the bottom plate therethrough is defined in one face of the edge. ### Claim 15 (depends on 14) The foldable display apparatus of claim 14, wherein the panel through-hole is defined in each of at least two faces of the edge. ### Claim 16 (depends on 14) The foldable display apparatus of claim 14, further comprising: a second support disposed between the first support and the edge. ### Claim 17 (depends on 16) The foldable display apparatus of claim 16, further comprising: an LM guide disposed inwardly of the second support; and a guide fastening portion movable with respect to the LM guide. ### Claim 18 (depends on 17) The foldable display apparatus of claim 17, further comprising: a bellows guide bar disposed inside the bellows and coupled to the guide fastening portion. ### Claim 19 (depends on 14) The foldable display apparatus of claim 14, further comprising: a first accommodation portion defined beneath the first support and a second accommodation portion defined beneath the bellows; and a driver of the display panel disposed in at least one of the first accommodation portion and the second accommodation portion.
