The rotation member (430) may be exposed through the adjustment groove (312) and the opening (210b) formed in the upper frame (210). The rotation member (430) may be accessible through the opening (210b). A user can adjust the height of the display module (100) by rotating the exposed rotating member (430). The user can easily adjust the height of the display module (100) from the rear of the display module (100) without separating the display module (100) from the cabinet (200). Accordingly, the work required to adjust the height of the display module (100) can be reduced, and the time required for height adjustment can be reduced.

[0100] However, the rotating member (430) may not be placed within the upper frame (210), but may be placed outside the upper frame (210) and the cabinet (200).

[0101] Fig. 11 is a perspective view of a display device according to one embodiment. Fig. 12 is a cross-sectional view of a display device according to one embodiment. Fig. 11 is an enlarged view of area B illustrated in Fig. 8.

[0102] Referring to FIGS. 11 and 12, the display (10) may include an adjustment part (410). The adjustment part (410) may be provided in the display module (100). The adjustment part (410) may be accommodated in the cabinet (200). For example, the adjustment part (410) may be placed in the upper frame (210). The adjustment part (410) may be provided in the display module (100). The adjustment part (410) may be fastened, coupled, and / or fixed to the fixed frame (140). For example, the adjustment part (410) may be screw-coupled to the fixed frame (140). The adjustment part (410) may also be a component included in the display module (100).

[0103] The adjustment part (410) may be withdrawable and / or detachable from the cabinet (200). For example, the adjustment part (410) may be withdrawable from a receiving portion (210a) formed within the upper frame (210).

[0104] The adjustment part (410) may include a body (411). The body (411) may be positioned between the display module (100) and the upper frame (210). For example, the body (411) may be positioned between the fixed frame (140) and the upper frame (210) in the front-rear direction.

[0105] A fastening hole (410a) is formed in the body (411) of the adjustment part (410), and a fastening member is inserted into the fastening hole (410a) to fasten the adjustment part (410) and the fixed frame (140).

[0106] The adjustment part (410) may include a contact portion (413). The contact portion (413) may extend vertically from the body (411). The contact portion (413) may be in contact with the upper frame (210) and the fixed frame (140). For example, the contact portion (413) may be in contact with the front surface of the upper frame (210). In addition, for example, the contact portion may be in contact with an extension portion protruding toward the rear of the fixed frame (140). The adjustment part (410) may be supported by the extension portion of the fixed frame (140). Since the contact portion (413) of the adjustment part (410) is in contact with and supported by the upper frame (210) and the fixed frame (140), the adjustment part (410) may be moved vertically by the support member (420) without changing its position, thereby allowing the display module (100) to move vertically.

[0107] The adjustment part (410) may include a support member (412). The support member (412) may extend rearward from the adjustment part body (411). The support member (412) may contact the upper surface (420a) of the support member (420), and the adjustment part (410) may be supported by the support member (420). The support member (412) may be arranged between the upper frame (210) and the support member (420) in the vertical direction.

[0108] The adjustment part (410) may include an adjustment member, a bracket and / or a latch.

[0109] The display (10) may include a support member (420). The support member (420) may extend in one direction to support the adjustment part (410). The support member (420) may be movable along one direction. For example, the support member (420) may extend in an up-and-down direction to contact and support the adjustment part (410), and may be moved in the up-and-down direction to adjust the height of the adjustment part (410) and the display module (100). The support member (420) may be disposed within the receiving portion (210a) of the upper frame (210).

[0110] The support member (420) may include an extension portion (421). The extension portion (421) may extend in an up-down direction. The upper surface (410a) of the extension portion (421) of the support member (420) may be in contact with the lower surface (412a) of the support portion (412) of the adjustment part (410).

[0111] The support member (420) may include a coupling portion (422). A rotation member (430) may be coupled to the coupling portion (422). A screw thread or screw groove may be formed on the coupling portion (422) so that the rotation member (430) may be rotatably coupled. The coupling portion (422) may be formed on one side of the extension portion (421). For example, the coupling portion (422) may be formed below the extension portion (421). However, the coupling portion (422) may be formed above the extension portion (421), so that the coupling portion (422) may come into contact with the adjustment part (410). The coupling portion (422) may be inserted through the rotation body (431) of the rotation member (430).

[0112] The display may include a rotation member (430). The rotation part may be accommodated within the cabinet (200). For example, the rotation member (430) may be disposed within the upper frame (210). The rotation member (430) may be disposed within the receiving portion (210a) of the upper frame (210). The rotation member (430) may be rotatably coupled to the support member (420). The rotation member (430) may be configured to surround the support member (420). For example, the rotation body (431) of the rotation member (430) may be configured to surround the coupling portion (422) of the support member (420).

[0113] The rotating member (430) may include a rotating body (431). The rotating body (431) may be coupled to a coupling portion (422) of the support member (420). A screw thread or screw groove may be formed on the inner surface forming the hole (410a) of the rotating body (431) so that the rotating body (431) may be rotatably coupled to the coupling portion (422). The rotating body (431) may protrude in the vertical direction.

[0114] The rotating body (431) of the rotating member (430) can be supported by the upper frame (210). For example, the rotating body (431) can be supported by the frame bottom (211) forming the receiving portion (210a). Since the rotating body (431) of the rotating member (430) is supported by the frame bottom (211), the rotating member (430) can move the supporting member (420) up and down through rotation without moving up and down.

[0115] The upper frame (210) may be a support frame (210) configured to support a rotating member (430). The frame bottom (211) may be a support frame (210) forming an opening (210b) in the upper frame (210). The frame bottom (211) may be the lower portion of the upper frame (210).

[0116] The rotating member (430) may include a manipulation part (432). The manipulation part (432) may protrude from the rotating body (431). For example, the manipulation part (432) may be formed on a side opposite to the hole (431a) of the rotating body (431). The manipulation part (432) may protrude in the radial direction of the rotating body (431). The manipulation part (432) may be exposed to the outside of the upper frame (210) through an opening (210b) of the upper frame (210). The manipulation part (432) may be accessible through the opening (210b). The opening (210b) may include a front opening (210b) formed in the front of the upper frame (210) and a rear opening (210b) formed in the rear. For example, at least a portion of the operating section (432) may be exposed to the outside through the rear opening (210b).

[0117] A user can rotate and move the rotation member (430) by manipulating the operating part (432) exposed through the opening (210b), thereby causing the support member (420) to move the adjustment part (410) and the display module (100). Accordingly, a user can adjust the height of the display module (100) through the rear opening (210b) without detaching the display module (100) forward.

[0118] In addition, by separating only the substrate (110) and the first reinforcing frame (121, 122) provided on the upper side of the display module (100), the height of the display module (100) can be adjusted through the front opening (210b) formed on the front side of the upper frame (210). Accordingly, the user can move the position of the display module (100) without separating the entire display module (100).

[0119] Accordingly, even if the display (10) is not placed at the top, the height of the display module (100) of the display (10) placed in the middle and / or lower position can be adjusted without separating the stacked displays (10).

[0120] Additionally, the height of the display module (100) can be adjusted through the opening (210b) even during product installation.

[0121] Ultimately, the user can easily adjust the height of the display module (100) while the display (10) is being laminated and installed, or even after installation is complete, and the time and work required for height adjustment can be reduced.

[0122] The support member (420) and / or the rotation member (430) may be an adjustment member. For example, the support member (420) may be a first adjustment member. For example, the rotation member (430) may be a second adjustment member.

[0123] The display may include a height adjustment device, and the height adjustment device may include an adjustment part, a first adjustment member, and a second adjustment member.

[0124] Below, the position movement mechanism of the display module (100) is described.

[0125] Fig. 13 is a perspective view of a display device according to one embodiment. Fig. 14 is a cross-sectional view of a display device according to one embodiment. Fig. 15 is a cross-sectional view of a display device according to one embodiment.

[0126] FIG. 13 is an enlarged perspective view showing that the support member (420) has been moved to the second position (P2), FIG. 14 is a cross-sectional view showing that the support member (420) is in the first position (P1), and FIG. 15 is a cross-sectional view showing that the support member (420) is in the second position (P2).

[0127] Referring to FIGS. 13 to 15, the display can move the support member (420) and the display module (100) in the up-and-down direction by rotating the rotation member (430). For example, when the rotation member (430) is rotated in the first rotation direction while being supported by the upper frame (210), the support member (420) can move upward. When the support member (420) moves upward, the adjustment part (410) supported by the support member (420) can also move upward. When the adjustment part (410) moves upward, the display module (100) coupled to the adjustment part (410) can also move upward.

[0128] For example, based on the rotation of the rotating member (430) in the first rotational direction, the support member (420), the adjustment part (410), and the display module (100) can be moved from the first position (P1) to the second position (P2).

[0129] As the adjustment part (410) moves from the first position (P1) to the second position (P2) within the upper frame (210), the support part (412) of the adjustment part (410) may come closer to the upper part (212) of the upper frame (210). The support part (412) of the adjustment part (410) may come into contact with the upper part (212) of the upper frame (210).

[0130] However, the direction of rotation of the rotating member (430) may be different from that shown in the drawing.

[0131] Fig. 16 is a perspective view of a display device according to one embodiment. Fig. 17 is a cross-sectional view of a display device according to one embodiment. Fig. 18 is a cross-sectional view of a display device according to one embodiment.

[0132] Fig. 16 is an enlarged perspective view showing that the support member (420) has been moved to the first position (P1), Fig. 17 is a cross-sectional view showing that the support member (420) is in the second position (P2), and Fig. 18 is a cross-sectional view showing that the support member (420) is in the first position (P1).

[0133] Referring to FIGS. 16 to 18, the display (10) can move the support member (420) and the display module (100) up and down by rotating the rotation member (430). For example, when the rotation member (430) is rotated in a second rotation direction opposite to the first rotation direction while being supported by the upper frame (210), the support member (420) can move downward. When the support member (420) moves downward, the adjustment part (410) supported by the support member (420) can also move downward. When the adjustment part (410) moves downward, the display module (100) coupled to the adjustment part (410) can also move downward.

[0134] For example, based on the rotation of the rotating member (430) in the second rotational direction, the support member (420), the adjustment part (410), and the display module (100) can be moved from the second position (P2) to the first position (P1).

[0135] As the adjustment part (410) moves from the second position (P2) to the first position (P1) within the upper frame (210), the support part (412) of the adjustment part (410) may be moved away from the upper portion (212) of the upper frame (210).

[0136] However, the direction of rotation of the rotating member (430) may be different from that shown in the drawing.

[0137] Since the support member (420) moves only in the up-down direction and the rotation member (430) moves only in the rotational direction, the display module (100) can only move in the up-down direction and not in the horizontal direction.

[0138] The plurality of displays (10) may experience thermal expansion of related components as the LEDs, substrates (110), and electrical components generate heat. While the plurality of displays (10) are stacked vertically and operated, the plurality of display modules (100) provided on the first display (10) may thermally expand and apply force to another display module (100) provided on the adjacent second display (10). This may result in deformation and / or damage to the display (10).

[0139] However, according to one embodiment, the display (10) can move the support member (420), the adjustment part (410), and the display module (100) by rotating the rotation member (430) through the operation unit (432). Therefore, the display module (100) of the first display (10) and the display module (100) of the adjacent second display (10) can be spaced apart from each other, and force can be prevented from being applied between different display modules (100). Consequently, force applied to other display modules (100) due to thermal expansion can be prevented, thereby minimizing deformation of the display module (100).

[0140] In addition, even when the distance between the plurality of display modules (100) in the adjacent plurality of displays (10) is far and the seam is highlighted, the seam can be minimized by adjusting the height to bring the plurality of displays (10) closer together.

[0141] In addition, since the support member (420) supports the display module (100), the display module (100) can be prevented from sagging due to a load.

[0142] According to one aspect of the present disclosure, a display device capable of easily adjusting the height of a display module can be provided by minimizing separation of related components.

[0143] According to one aspect of the present disclosure, a display device can be provided that can prevent damage to a display module due to thermal expansion by easily adjusting the height.
