At this time, the size of the first opening 142 is larger than the cross section of the wall fixing pin 133 . Accordingly, the wall fixing pin 133 may flow within the first opening 142 . In this case, the length from the outer surface of the wall fixing pin 133 to the boundary surface of the first opening 142 may be equal to or similar to the first length AM.

The second opening 143 of the back cover 140 is disposed on the protrusion 141P of the back cover 140 . The second opening 143 is an opening through which the second magnet 125 and the support shaft 123 pass. The first plate 121 is disposed so as to overlap the protrusion 141P of the back cover 140, and the support shaft 123 extending from the first plate 121 to the rear side of the back cover 140 has a second opening ( 143) and may extend toward the rear side of the back cover 140.

Meanwhile, the size of the second opening 143 of the back cover 140 may be larger than the sizes of the support shaft 123 , the second magnet 125 , and the cover part 126 . Accordingly, the support shaft 123 , the second magnet 125 , and the cover part 126 may flow within the second opening 143 .

Also, the second opening 143 may expose a portion of the fixing plate 131 disposed between the first plate 121 and the back cover 140 . In this case, the second magnet 125 may move along the support shaft 123 and pass through the second opening 143 having a larger size than the second magnet 125, and exposed from the second opening 143. It may come into contact with the fixed plate 131 . Accordingly, the display panel 110 and the back cover 140 may be fixed to the wall fixing part 130 by contacting the second magnet 125 with the fixing plate 131 .

For example, when the first magnet 124 rotates so that the N pole of the first magnet 124 and the S pole of the second magnet 125 overlap, the second magnet 125 is attracted to the first magnet. It can move in a direction closer to (124). That is, the second magnet 125 may move toward the fixing plate 131 by attraction. Accordingly, the distance between the first magnet 124 and the second magnet 125 may be the same as the thickness of the fixing plate 131 . That is, as the first magnet 124 and the second magnet 125 are attached to each other with the fixing plate 131 therebetween, the display panel 110 and the back cover 140 can be fixed to the wall fixing part 130. there is.

Meanwhile, the rotation of the first magnet 124 causes the second magnet 125 to move along the support shaft 123 . For example, when the first magnet 124 rotates so that the N pole of the first magnet 124 and the N pole of the second magnet 125 overlap, the second magnet 125 is driven by a repulsive force. It can move in the direction away from (124). That is, the second magnet 125 may move toward the cover part 126 by a repulsive force. Accordingly, the distance between the first magnet 124 and the second magnet 125 may be greater than the thickness of the fixing plate 131 . Accordingly, as the distance between the first magnet 124 and the second magnet 125 increases, the display panel 110 and the back cover 140 may slip away from the wall fixing part 130 .

Hereinafter, with reference to FIGS. 5A to 5D , a process of rearranging the spacing and arrangement between the plurality of display devices 100 using the attraction and repulsive force between the first magnet 124 and the second magnet 125 will be described. .

5A to 5E are cross-sectional views illustrating a process of arranging a display device according to an exemplary embodiment of the present invention. It is assumed that the wall fixing part 130 of the display device 100 according to the exemplary embodiment shown in FIGS. 5A to 5E is fixed to the wall part 200 and will be described. However, in FIGS. 5A to 5E, illustration of the wall part 200 is omitted for convenience of description.

First, referring to FIG. 5A , since it is assumed that the wall fixing part 130 of the display device 100 is fixed to the wall part 200, the first magnet 124 has a polarity opposite to that of the second magnet 125. The parts are arranged so that they overlap. Specifically, the plurality of N poles 124N of the first magnet 124 are arranged to overlap the plurality of S poles 125S of the second magnet 125, and the plurality of S poles of the first magnet 124 ( 124S) is disposed to overlap the plurality of N poles 125N of the second magnet 125 . Thus, an attractive force is generated between the first magnet 124 and the second magnet 125 .

Accordingly, the first magnet 124 and the second magnet 125 may be disposed in a fixed state with the fixing plate 131 interposed therebetween. And as the first magnet 124 and the second magnet 125 are fixed to the fixing plate 131, the support shaft 123, the first plate 121, the cover part 126, the back cover 140 and The display panel 110 may also be disposed while being fixed to the wall fixing part 130 .

Specifically, an attractive force between the first magnet 124 and the second magnet 125 may be generated so that the first magnet 124 and the second magnet 125 may be fixed with the fixing plate 131 interposed therebetween. The first magnet 124 and the second magnet 125 may be fixed while being in contact with the fixing plate 131 . Accordingly, the support shaft 123 penetrating the first magnet 124 and the second magnet 125 may be fixed without moving within the fixing opening 132 of the fixing plate 131 . The first plate 121 to which the support shaft 123 is connected, the back cover 140 fixed to the first plate 121 through the fixing member 122, and the display panel 110 fixed to the back cover 140 It can also be fixed without floating. Accordingly, when portions of different polarities of the first magnet 124 and the second magnet 125 overlap each other, the display panel 110, the back cover 140, and the first plate ( 121), the first magnet 124, the support shaft 123, the second magnet 125, and the cover part 126 may be fixed.

However, when the display panel 110 of the display device 100 fixed to the wall fixing part 130 is distorted from the display panel 110 of another adjacent display device 100 in the X-axis direction and/or the Y-axis direction, The display panel 110, the back cover 140, and the first plate ( 121), the fixing member 122, the first magnet 124, the support shaft 123, the second magnet 125, and the cover part 126 may be slipped from the wall fixing part 130.

First, referring to FIG. 5A , the third magnet 300 may be disposed on the front surface of the display panel 110 . The third magnet 300 may be disposed such that a portion of opposite polarity overlaps with the first magnet 124 on the rear surface of the display panel 110 . For example, the plurality of N poles 300N of the third magnet 300 are arranged to overlap the plurality of S poles 124S of the first magnet 124, and the plurality of S poles of the third magnet 300 overlap. 300S is disposed so as to overlap the plurality of N poles 124N of the first magnet 124. Accordingly, an attractive force is generated between the third magnet 300 and the first magnet 124 so that the first magnet 124 and the third magnet 300 interpose the display panel 110 and the first plate 121. can be fixed

In addition, when the third magnet 300 is rotated, the first magnet 124 may also rotate due to gravitational force. For example, after placing the N pole 300N of the third magnet 300 to overlap the S pole 124S of the first magnet 124 and then rotating the third magnet 300, the first magnet 124 The S pole 124S of ) may also rotate along the N pole 300N of the third magnet 300.

At this time, as the first magnet 124 rotates, the second magnet 125 disposed so that the opposite polarity portion overlaps with the first magnet 124 also attracts between the first magnet 124 and the second magnet 125. may try to rotate by However, in the case of the second magnet 125, since the second portion 123b of the support shaft 123 penetrating the second magnet 125 has a polygonal shape, it cannot rotate along the first magnet 124. That is, in a state in which the second magnet 125 is fixed not to rotate by the second part 123b of the support shaft 123, only the first magnet 124 rotates together with the rotation of the third magnet 300. can do.

Subsequently, referring to FIG. 5B, the first magnet 124 is rotated by the rotation of the third magnet 300, and the N pole 124N of the first magnet 124 is the N of the second magnet 125. It may be arranged to overlap the pole 125N. Accordingly, the first magnet 124 and the second magnet 125 may be disposed so that portions of the same polarity overlap. That is, a repulsive force between the first magnet 124 and the second magnet 125 may occur.

In addition, the second magnet 125 can move away from the first magnet 124 along the support shaft 123 due to the repulsive force with the first magnet 124, and the second magnet 125 is the fixed plate 131 ) and can come into contact with the cover portion 126.

Referring to FIG. 5C , as the first magnet 124 and the second magnet 125 are spaced apart from each other, the fixing plate 131 between the first magnet 124 and the second magnet 125 and the back cover 140 ) of the protruding portion 141P may be slipped. Specifically, the fixing plate 131 is only inserted into the protrusion 141P of the back cover 140, and the fixing plate 131 and the back cover 140 are not fixed. When the fixed plate 131 is fixed to the wall portion 200, the first magnet 124 and the protrusion 141P of the back cover 140 may slip while being in contact with the fixed plate 131. Accordingly, the first plate 121 and the display panel 110 fixed to the back cover 140, the fixing member 122, the first magnet 124, the second magnet 125, the support shaft 123 and The cover part 126 can move together.

The second magnet 125 is moved to come into contact with the cover part 126 so that the fixing plate 131 is not fixed by the first magnet 124 and the second magnet 125, the inside of the protrusion part 141P. The side surface may slip along the X-axis direction and/or the Y-axis direction while being in contact with the fixed plate 131 . That is, the protruding portion 141P may flow on the Z-axis plane while being in contact with the fixed plate 131 . For example, when the display panel 110 of the display device 100 is misaligned with the display panel 110 of the adjacent display device 100 in the Y-axis direction, the protrusion 141P is in contact with the fixing plate 131. It can be slipped in the Y-axis direction. Therefore, a repulsive force is generated between the first magnet 124 and the second magnet 125 to form the back cover 140, the first plate 121 and the display panel 110 fixed to the back cover 140, and the first The magnet 124, the second magnet 125, the support shaft 123, and the cover part 126 may be moved in the Y-axis direction.

For example, the distance between the fixed plate 131 and the protrusion 141P of the back cover 140 in the Y-axis direction may be the first length AM. At this time, when distortion occurs in the Y-axis direction and the back cover 140 is slipped in the Y-axis direction, the distance between the protrusion 141P of the back cover 140 and the fixing plate 131 on one side is the first length (AM). ) to the second length AM', and the distance between the protrusion 141P of the back cover 140 and the fixing plate 131 on the other side is from the first length AM to the third length AM'' can be increased to

Next, referring to FIG. 5D , after arranging the spacing and arrangement of each display panel 110 of the plurality of display devices 100 in the Y-axis direction or the X-axis direction, the first magnet 124 is rotated to fix the wall surface. The back cover 140 on the top 130, the first plate 121 fixed to the back cover 140, the fixing member 122 and the display panel 110, the first magnet 124, the second magnet ( 125), the support shaft 123 and the cover part 126 may be fixed.

Specifically, after aligning the spacing and arrangement of the display panels 110 of the plurality of display devices 100 , the third magnet 300 may be disposed on the front surface of the display panel 110 again. In this case, the third magnet 300 may be disposed such that a portion of opposite polarity overlaps with the first magnet 124 on the rear surface of the display panel 110 . Accordingly, an attractive force is generated between the third magnet 300 and the first magnet 124, so that the first magnet 124 may also rotate along with the rotation of the third magnet 300.

Finally, referring to FIG. 5E, the rotation of the third magnet 300 causes the first magnet 124 to rotate, and the first magnet 124 has an N pole 124N of the second magnet 125. It may be arranged to overlap the S pole 125S. That is, the first magnet 124 and the second magnet 125 may be disposed so that portions of opposite polarities overlap, and an attractive force between the first magnet 124 and the second magnet 125 may occur.

The second magnet 125 may move in a direction closer to the first magnet 124 due to an attractive force with the first magnet 124 . The second magnet 125 may move toward the first magnet 124 along the support shaft 123 and contact the fixed plate 131 . Therefore, since the second magnet 125 and the first magnet 124 are fixed in a state in contact with the fixing plate 131 by attraction, the first magnet 124 and the second magnet 125 and the display panel 110 ), the first plate 121, the support shaft 123, the fixing member 122, the cover part 126 and the back cover 140 may be fixed to the wall fixing part 130.

Conventionally, a tiling display device in which a plurality of display devices are arranged may be implemented by attaching each of the plurality of display devices to a wall portion. In this case, it is possible to minimize the visibility of the boundary between the plurality of display devices by arranging the distance between the plurality of display devices at a constant level while the plurality of edges of each of the plurality of display devices are brought into close contact with each other as much as possible. However, even if the plurality of display devices are aligned and attached to the wall surface, slight distortions may occur between the plurality of display devices due to the process of manually attaching the plurality of display devices by a worker or due to mechanical tolerances. The quality of displayed images may be degraded. In addition, when a plurality of display devices are distorted, the process of disassembling the plurality of display devices from the wall portion and then reassembling them must be repeated, which increases the time and cost of assembling the tiling display device.

Thus, the tiling display device 1000 according to an embodiment of the present invention, in a state in which the plurality of display devices 100 are attached to the wall portion 200, without disassembling and reassembling the plurality of display devices 100. Intervals and distortions between the plurality of display devices 100 may be adjusted. First, each of the plurality of display devices 100 may be attached to, ie, fixed to, the wall part 200 through the wall fixing part 130 . At this time, the fixing plate 131 of the wall fixing part 130 is inserted between the display panel 110 and the back cover 140 of the display device 100, and the first magnet 124 and the second magnet 125 As a result, the fixing plate 131 , the display panel 110 , and the back cover 140 may be selectively fixed. Specifically, the first magnet 124 is disposed between the display panel 110 and the fixing plate 131, and the second magnet 125 is disposed with the first magnet 124 and the fixing plate 131 interposed therebetween. And, the support shaft 123 passing through the first magnet 124 and the second magnet 125 at the same time is disposed. At this time, the first magnet 124 cannot move between the display panel 110 and the fixing plate 131 in a direction perpendicular to the rear surface of the display panel 110, and only rotates about the support shaft 123. This is possible, and the second magnet 125 can move along the support shaft 123 in a direction perpendicular to the rear surface of the fixing plate 131, but cannot rotate. First, when opposite polarity portions of the first magnet 124 and the second magnet 125 overlap each other, the second magnet 125 may move toward the first magnet 124 due to attractive force. And as the first magnet 124 and the second magnet 125 are fixed with the fixing plate 131 therebetween, the first magnet 124, the second magnet 125, the support shaft 123, the first The plate 121 , the fixing member 122 , the back cover 140 , and the display panel 110 may be disposed while being fixed to the fixing plate 131 .

If it is necessary to adjust the spacing and distortion between the display panels 110 of the plurality of display devices 100 in the X-axis direction and/or the Y-axis direction, the first magnet 124 and the second magnet 125 are identical. By overlapping the polarity portions, the display panels 110 and the back cover 140 of the plurality of display devices 100 are slipped from the fixing plate 131 to determine the distance between the display panels 110 of the plurality of display devices 100 and You can adjust the twist. After the third magnet 300 is disposed on the front surface of the display panel 110 so that an attractive force is generated with the first magnet 124, the third magnet 300 may be rotated to rotate the first magnet 124. . In addition, the first magnet 124 whose opposite polarity part overlaps with the second magnet 125 can be rotated by the third magnet 300 so that the second magnet 125 and the same polarity part overlap. When parts of the same polarity of the first magnet 124 and the second magnet 125 overlap each other, the second magnet 125 may move away from the first magnet 124 due to a repulsive force. Accordingly, since the first magnet 124 and the second magnet 125 are not fixed with the fixing plate 131 interposed therebetween, the first magnet 124 may flow while being in contact with the fixing plate 131 . Accordingly, the second magnet 125 is spaced apart from the fixing plate 131, and the first magnet 124, the second magnet 125, the support shaft 123, the first plate 121, and the fixing member 122 , The back cover 140 and the display panel 110 may be moved in a direction along one surface of the fixing plate 131 , and spacing and distortion between the plurality of display devices 100 may be adjusted. Therefore, the tiling display device 1000 according to an exemplary embodiment of the present invention provides the plurality of display devices 100 even when the wall fixing parts 130 of the plurality of display devices 100 are fixed to the wall part 200. Since the distance and twist between the display panels 110 can be adjusted, disassembly or assembly of the plurality of display devices 100 is unnecessary, and maintenance and repair are easy. In addition, even in a state in which the wall fixing parts 130 of the plurality of display devices 100 are fixed to the wall part 200, fine distortions or gaps between the plurality of display devices 100 can be easily adjusted, so that a plurality of display devices 100 can be easily adjusted. The visibility of the boundary area between the devices 100 can be minimized, and the quality of an image displayed on the tiling display device 1000 can be improved.
