When the separation device 400 is used to detach the display module 100 from the cabinet 200, the extension portion 412 may extend from the grip portion 411 toward the display module 100. For example, the extension portion 412 may extend in a direction perpendicular to the direction in which the grip portion 411 extends.

[0111] The extension portion 412 may include a first portion 412a and a second portion 412b. The first portion 412a may be connected to the grip portion 411. The second portion 412b may extend from the first portion 412a. One end of the first portion 412a may be connected to the grip portion 411, and the other end may be connected to the second portion 412b. The first portion 412a may have a larger cross-sectional area than the second portion 412b.

[0112] The second portion 412b may be formed with an insertion hole 413 into which a fastener is inserted. The insertion holes 413 may be formed corresponding to the number of fasteners 460. The insertion holes 413 may be formed along an extension direction of the extension portion 412. At least a portion of the second portion 412b may be received in a case 420. For example, the second portion 412b may receive a head 431 and plates, which will be described later, between the second portion 412b and the case 420.

[0113] The separation device 400 may further include the case 420.

[0124] The first plate 440 may prevent the insertion member 430 from moving in a linear direction when the insertion member 430 is coupled to the body 410. One surface 440a of the first plate 440 and one surface 431b of the head 431 may contact each other to prevent the insertion member 430 from moving in a linear direction. For example, the first plate 440 may contact a surface of the head 431 facing the display module 100 to prevent the insertion member 430 from moving in the linear direction.

[0125] The first plate 440 may further include a fixing hole 442. The fastener 460 may pass through the fixing hole 442. The first plate 440 may be coupled to the body 410 by the fastener 460 passing through the fixing hole 442. The fixing holes 442 may be provided in a corresponding number of the fasteners 460.

[0126] The separation device 400 may further include the second plate 450. The second plate 450 may be coupled to the insertion member 430. The second plate 450 may prevent rotation of the insertion member 430. In addition, the fastener 460 may pass through the second plate 450 to secure the second plate 450 to the body 410. The second plate 450 may be accommodated within the case 420.

[0127] The second plate 450 may include an anti-rotation portion 451. The head 431 of the insertion member 430 may be inserted into the anti-rotation portion 451. The anti-rotation portion 451 may be formed to correspond to the perimeter 431a of the head. In the drawings, the anti-rotation portion 451 is shown as a hole, but may be provided in various shapes, such as a groove shape.

[0128] The second plate 450 may prevent the insertion member 430 from rotating when the insertion member 430 is coupled to the body 410. For example, the anti-rotation portion 451 may contact the perimeter 431a of the head to prevent the insertion member 430 from rotating. The anti-rotation portion 451 may be fitted to the perimeter 431a of the head. The anti-rotation portion 451 and the perimeter 431a of the head may each include a polygonal shape.

[0129] The second plate 450 may further include a fixing hole 452. The fastener 460 may pass through the fixing hole 452. The second plate 450 may be coupled to the body 410 by the fastener 460 passing through the fixing hole 452. The fixing holes 452 may be provided in a corresponding number of the fasteners 460.

[0130] The second plate 450 may be more adjacent to the body 410 than the first plate 440. However, such an arrangement of the first plate 440 and the second plate 450 is not limited to the examples described above. Furthermore, although the separation device 400 has been described as including the plurality of plates 440 and 450, the separation device 400 of the present disclosure may prevent linear movement and rotation of the insertion member 430 through a single plate.

[0131] FIGS. 12 to 14 are views illustrating a process by which the separation device is mounted to the display module in the display device according to an embodiment. FIGS. 12 to 14 are enlarged views of region B in FIG. 2. While FIGS. 12 to 14 are described based on the upper right region of a display module, the separation device of the display device according to an embodiment may also be used in regions other than the above region.

[0132] Referring to FIGS. 12 to 14, the separation device 400 according to an embodiment of the disclosure may be detachably mounted to the display module 100. The separation device 400 may allow the display module 100 to be pulled forward and detached from the cabinet 200.

[0133] Referring to FIG. 12, the fastening members 30 for coupling the substrate 110, the holder 120, and the cover plate 130 may be detached from the fastening holes 136 arranged in the display module 100. In this case, the fastening members 30 may be, for example, the fastening members 30 disposed at a perimeter and/or corner portions of the display module 100.

[0134] Referring to FIG. 13, the separation device 400 may be inserted into the display module 100 from which the fastening member 30 has been uncoupled. To detach the display module 100 from the cabinet 200, the fastening member 30 may be uncoupled from the fastening holes 136 and 113, and then the insertion member 430 may be inserted into a portion of the fastening holes 136 and 113. For example, the insertion portion 432 in which the thread 432a of the insertion member 430 is formed may be inserted into the cover plate 130.

[0135] Referring to FIG. 14, the separation device 400 may be rotated in one direction to be inserted deeper into the fastening holes 136 and 113 of the display module 100. For example, the insertion member 430 of the separation device 400 may include the thread 432a, so that the separation device 400 may be rotated and inserted into the substrate 110 and the cover plate 130. The separation device 400 may be rotated so that the insertion member 430 is secured to the display module 100. For example, the separation device 400 may be rotated so that the insertion portion 432 is secured to the receiving portion 124a of the holder 120 and the substrate fastening hole 113. The direction in which the separation device 400 may be rotated is not limited to that shown in the drawings.

[0136] In this case, since the anti-rotation portion 451 arranged on the second plate 450 holds the head 431, the insertion member 430 may not rotate and the separation device 400 may rotate, allowing the separation device 400 to be inserted and secured within the display module 100. In other words, the insertion member 430 does not idle, allowing the separation device 400 to be secured within the display module 100.

[0137] By rotating the separation device 400 to insert it into the display module 100, the user may intuitively identify the extent to which the separation device 400 is coupled to the display module 100. Thus, workability for the user may be enhanced.

[0138] Furthermore, instead of newly creating a separate separation structure within the display module 100, it is only necessary to decouple the fastening member 30 used for coupling the substrate 110, the holder 120, and the cover plate 130, and then insert and couple the separation device 400 to the fastening holes 136 and 113 and the receiving portion 124a (see FIG. 16), thereby simplifying the structure of the display module 100 and reducing production costs.

[0139] FIG. 15 is a cross-sectional view of the display device shown in FIG. 14. FIG. 16 is an enlarged view of the display device shown in FIG. 15. FIG. 15 is a cross-sectional view of the display device of FIG. 14 cut along line D-D. FIG. 16 is an enlarged view of region E of FIG. 15.

[0140] Referring to FIGS. 15 and 16, the holder 120 may include the support portion 122 and a coupling protrusion 123 protruding from the support portion 122.

[0141] The support portion 122 may include a first support portion 122a, and the coupling protrusion 123 may protrude from the first support portion 122a. A first receiving portion 124a may be formed within the first support portion 122a. The coupling protrusion 123 may be fastened with the fastening member 30 to allow the cover plate 130, the substrate 110, and the holder 120 to be coupled. The first receiving portion 124a may be provided within the coupling protrusion 123 so that the insertion member 430 or a coupling member may be inserted. The coupling protrusion 123 may pass through the substrate fastening hole 113 to support the cover plate 130. The diameter of the substrate fastening hole 113 may be larger than the diameter of the coupling protrusion 123.

[0142] A second receiving portion 124b may be formed within a second support portion 122b. The fastening member 30 for coupling the substrate 110 and the holder 120 may be disposed within the second support portion 122b.

[0143] Referring to FIG. 16, the insertion portion 432 of the separation device 400 may be disposed within the fastening hole 136 of the cover plate 130, the substrate fastening hole 113, and the first receiving portion 124a. The thread 432a may be inserted into the substrate fastening hole 113 and the first receiving portion 124a, so that the separation device 400 may be secured to the display module 100.

[0144] FIG. 17 is a view illustrating a state in which the display module is detached from the cabinet in the display device according to an embodiment.

[0145] Referring to FIG. 17, the user may separate the display module 100 from the cabinet 200 by pulling the separation device 400, which is coupled and fixed to the display module 100, toward the front side.

[0146] For example, when a force greater than or equal to the magnetic attraction is applied via the separation device 400 to cause the display module 100 to detach from the cabinet 200, the display module 100 may be separated from the cabinet 200.

[0147] Since one portion of one display module 100 that was coupled to the cabinet 200 has been detached from the cabinet 200, the other portion of the display module 100 may also be easily detached from the cabinet 200 by pulling the display module 100.

[0148] The user may easily detach the display module 100 from the cabinet 200 by inserting and coupling the separation device 400 into the fastening holes 136 and 113 and the receiving portion 124a, and then pulling the display module 100 forward. Thus, when the display module 100 needs to be repaired, visibility and workability may be improved by visually checking the assembly and disassembly status from the front.

[0149] Although certain example embodiments are illustrated and described above, the present disclosure is not limited to the certain embodiments, various applications may of course be performed by those skilled in the art without deviating from what is claimed in the scope of claims, and such applications should not be understood separately from the technical idea or prospects herein.
