The pipe ring 225 and the main column 215 may be coupled by a second wrench 414 . For example, the second wrench 414 may be a 4 mm wrench.

Since the at least one bar 231 and the pipe ring 225 are fixed using the main column 215 and the first and second wrenches 412 and 414 , the user can use the at least one bar 231 and the pipe ring 225 . ) may not be concerned about being easily separated from the main pillar 215 .

Referring to FIG. 20 , finally, the plurality of display devices 100 coupled to the multi-row stand 200 and the plurality of other coupled display devices 100 may be connected. The plurality of display apparatuses 100 may be connected using the connecting bar 300 .

In detail, the second surfaces 313 of the connecting bar 300 may be coupled to each other using a fixing screw 319 and a nut 515 .

The connecting bar 300 is in contact with the other connecting bar 300 due to the protrusion 525 protruding in the direction perpendicular to the second surface 313 at the boundary line between the first surface 315 and the second surface 313. may not In addition, since the spring 527 is positioned at a portion between the connecting bars 300 of the fixing screws 319, when the connecting bars 300 are close to each other, the distance may be increased due to elasticity.

The display apparatus 100 may not contact each other by the protrusion 525 and the spring 527 of the connecting bar 300 . In addition, the connecting bar 300 may be easy to adjust the fine spacing by the protrusion 525 and the spring 527 .

21 is a diagram illustrating a display device according to another embodiment of the present invention.

Referring to FIG. 21 , in the display device 100 according to the present invention, a gender 357 may be located in the center of the rear surface to be used for wall hanging. Gender 357 may be in the shape of a rectangle or square, for example. The gender 357 may have a triangular shape, for example.

The gender 357 may be coupled to the connection member 471 located in the center of the rear surface of the display apparatus 100 . The connection member 471 may protrude in the thickness direction of the display apparatus 100 . In detail, the guide protrusion 513 of the gender 357 may be inserted into the seating hole 484 in the connection member 471 . The seating hole 484 is recessed inside the connecting member 471 , and the guide protrusion 513 may protrude from the gender 357 to the connecting member 471 . After the guide protrusion 513 is inserted into the seating hole 484 , the gender 357 may be fixed to the connection member 471 by a fixing screw.

The user can produce the solid wall-mounted display device 100 by the gender 357, and when wall hanging is not required, the gender 357 can be separated from the connection member 471 so that the user can recognize a neat appearance. have. By the connection member 471, users can select whether to use the wall hanging, and price competitiveness can be secured.

The above detailed description should not be construed as restrictive in all respects and should be considered as illustrative. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are included in the scope of the present invention.
