The first opening 142 of the back cover 140 is disposed in the protrusion 141P of the back cover 140. The first opening 142 is an opening through which the wall fixing pin 133 of the wall fixing unit 130 passes. The fixing plate 131 of the wall fixing portion 130 is disposed to overlap the protrusion 141P of the back cover 140, and the wall fixing pin 133 extending from the fixing plate 131 toward the back side of the back cover 140 ) May penetrate the first opening 142 of the back cover 140 and extend to the back side of the back cover 140. 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 in 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 the same as or similar to the first length AM.

The second opening 143 of the back cover 140 is disposed in 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 to overlap the protrusion 141P of the back cover 140, and the support shaft 123 extending from the first plate 121 toward the back side of the back cover 140 has a second opening ( 143) may be extended to the back side of the back cover 140.

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

In addition, 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 moves along the support shaft 123 and can penetrate the second opening 143 having a larger size than the second magnet 125 and is exposed from the second opening 143 It can be in contact with the fixed plate (131). Therefore, the display panel 110 and the back cover 140 may be fixed to the wall fixing unit 130 by the second magnet 125 contacting the fixing plate 131.

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

Meanwhile, the second magnet 125 may move along the support shaft 123 by rotation of the first magnet 124. For example, when the first magnet 124 rotates such that the N-pole and the second magnet 125 of the first magnet 124 overlap the N-pole, the second magnet 125 is driven by the repulsive force to the first magnet It can move in a direction away from (124). That is, the second magnet 125 may move toward the cover portion 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 fixed 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 from the wall fixing unit 130.

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

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

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

Therefore, the first magnet 124 and the second magnet 125 may be disposed in a fixed state with the fixing plate 131 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 portion 126, the back cover 140 and The display panel 110 may also be disposed fixed to the wall fixing part 130.

Specifically, the attraction between the first magnet 124 and the second magnet 125 is generated so that the first magnet 124 and the second magnet 125 can 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 flowing in the fixed opening 132 of the fixed plate 131. And the support plate 123 is connected to the first plate 121, the first plate 121 and the back cover 140 fixed through the fixing member 122, the back cover 140 and the fixed display panel 110 It can also be fixed without flow. Thus, when the different polar parts of the first magnet 124 and the second magnet 125 are arranged to overlap, 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 portion 126 may be fixed.

However, when the display panel 110 of the display device 100 fixed to the wall fixing unit 130 is distorted in the X-axis direction and / or the Y-axis direction with the display panel 110 of the other display device 100 adjacent, The first magnet 124 and the second magnet 125 fixed with the fixing plate 131 of the wall fixing unit 130 therebetween are spaced apart, and 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 portion 126 can be slipped from the wall fixing portion 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 the opposite polarity portion of the first magnet 124 on the rear surface of the display panel 110 overlaps. 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 300S is disposed 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 sandwich 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 by attraction. For example, after arranging the N pole 300N of the third magnet 300 to overlap the S pole 124S of the first magnet 124, rotating the third magnet 300 to rotate the first magnet 124 ) S pole 124S 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 is also attracted between the first magnet 124 and the second magnet 125. Can be rotated 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 is polygonal, it cannot rotate along the first magnet 124. That is, in the state in which the second magnet 125 is fixed so as not to be rotated by the second portion 123b of the support shaft 123, only the first magnet 124 is rotated together by 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 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 arranged to overlap the same polarity portion. That is, repulsive force between the first magnet 124 and the second magnet 125 may occur.

In addition, the second magnet 125 may move away from the first magnet 124 along the support shaft 123 due to repulsive force with the first magnet 124, and the second magnet 125 may have a fixed plate 131. ) Can be in contact with the cover portion 126.

Referring to Figure 5c, as the first magnet 124 and the second magnet 125 are spaced apart from each other, the fixing plate 131 and the back cover 140 between the first magnet 124 and the second magnet 125 ) Can cause the protrusion 141P to slip. Specifically, the fixing plate 131 is only inserted into the protrusion 141P of the back cover 140, 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 in contact with the fixed plate 131. Therefore, 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 portion 126 may move together.

The second magnet 125 is moved so as to contact the cover portion 126 so that the fixing plate 131 is not fixed by the first magnet 124 and the second magnet 125, and the inner portion of the protrusion 141P The side surface may slip along the X-axis direction and / or the Y-axis direction while being in contact with the fixing plate 131. That is, the protrusion 141P may flow on the Z-axis plane while in contact with the fixed plate 131. For example, when the display panel 110 of the display device 100 is distorted in the Y-axis direction with the display panel 110 of the adjacent display device 100, the protrusion 141P is in contact with the fixing plate 131 Can slip in the Y-axis direction. Accordingly, the first plate 121 and the display panel 110 fixed to the back cover 140 and the back cover 140 by generating repulsive force between the first magnet 124 and the second magnet 125, and the first The magnet 124, the second magnet 125, the support shaft 123, and the cover portion 126 may be moved in the Y-axis direction.

For example, a distance between the fixing 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 the back cover 140 slips in the Y-axis direction due to a distortion 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 ) Can be reduced to a second length (AM '), the distance between the protrusion 141P of the back cover 140 and the fixing plate 131 on the other side is the third length (AM' ') from the first length (AM) Can be increased to

Next, referring to FIG. 5D, after aligning the spacing and arrangement of the display panels 110 of each of the plurality of display devices 100 in the Y-axis direction or the X-axis direction, the first magnet 124 is rotated to rotate the wall surface height. The first cover 121 fixed to the back cover 140 and the back cover 140 to the government 130, the fixing member 122 and the display panel 110, the first magnet 124, the second magnet ( 125), the support shaft 123 and the cover portion 126 can be fixed.

Specifically, after arranging the spacing and arrangement of the display panels 110 of each of the plurality of display devices 100, the third magnet 300 may be disposed again on the front surface of the display panel 110. In this case, the third magnet 300 may be disposed such that the opposite polarity portion of the first magnet 124 on the rear surface of the display panel 110 overlaps. Accordingly, an attraction force between the third magnet 300 and the first magnet 124 is generated, and the first magnet 124 may also rotate together according to the rotation of the third magnet 300.

Finally, referring to FIG. 5E, the first magnet 124 is rotated by the rotation of the third magnet 300, and the N pole 124N is the second magnet 125 of the first magnet 124. It may be arranged to overlap the S pole (125S). That is, the first magnet 124 and the second magnet 125 may be arranged to overlap opposite polarities, and attraction 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 attraction with the first magnet 124. The second magnet 125 may move to the first magnet 124 side along the support shaft 123 to contact the fixed plate 131. Accordingly, since the second magnet 125 and the first magnet 124 are fixed in contact with the fixing plate 131 by an attractive force, the first magnet 124 and the second magnet 125 and the display panel 110 are fixed. ), The first plate 121, the support shaft 123, the fixing member 122, the cover portion 126 and the back cover 140 may be fixed to the wall fixing portion 130.

Conventionally, a tiled 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 surface. At this time, while the edges of each of the plurality of display devices are closely adhered to each other, the gaps between the plurality of display devices are constantly arranged to minimize the visibility of the boundaries between the plurality of display devices. However, even if a plurality of display devices are aligned and attached to the wall surface, a slight distortion may occur between the plurality of display devices due to a process of manually attaching the plurality of display devices or a mechanism tolerance, etc. The quality of the displayed image can be reduced. In addition, when a plurality of display devices are distorted, since the process of disassembling the plurality of display devices from the wall surface and reassembling them must be repeated, there is a difficulty in assembling and tiling the tiling display device.

Accordingly, the tiling display device 1000 according to an exemplary embodiment of the present invention does not disassemble and reassemble the plurality of display devices 100 while the plurality of display devices 100 are attached to the wall surface 200. The spacing and distortion between the plurality of display devices 100 may be adjusted. First, each of the plurality of display devices 100 may be attached to, or fixed to, the wall surface portion 200 through the wall fixing portion 130. At this time, the fixing plate 131 of the wall fixing unit 130 is inserted between the display panel 110 and the back cover 140 of the display device 100, the first magnet 124 and the second magnet 125 The fixing plate 131 and 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 fixed plate 131, and the second magnet 125 is disposed with the first magnet 124 and the fixed plate 131 therebetween. The support shaft 123 penetrating the first magnet 124 and the second magnet 125 at the same time is disposed. At this time, the first magnet 124 cannot be moved in a direction perpendicular to the rear surface of the display panel 110 between the display panel 110 and the fixed plate 131, and only rotates based on the support shaft 123 This is possible, and the second magnet 125 can move in a direction perpendicular to the rear surface of the fixed plate 131 along the support shaft 123, but cannot rotate. First, when the 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 by attraction. 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, and the first magnet The plate 121, the fixing member 122, the back cover 140 and the display panel 110 may be disposed in a fixed state on the fixing plate 131.

If, in the X-axis direction and / or Y-axis direction, it is necessary to control the spacing and distortion between the display panels 110 of the plurality of display devices 100, the first magnet 124 and the second magnet 125 are the same. By overlapping the polarity portions, the display panel 110 and the back cover 140 of the plurality of display devices 100 are slipped from the fixing plate 131, and the distance between the display panels 110 of the plurality of display devices 100 and The distortion can be adjusted. After the first magnet 124 and the third magnet 300 are arranged to generate an attractive force on the front surface of the display panel 110, the first magnet 124 may be rotated by rotating the third magnet 300. . In addition, the first magnet 124 in which the second polarity portion overlaps the second magnet 125 may be rotated by the third magnet 300 so that the same polarity portion overlaps with the second magnet 125. When the same polarity portions 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 by the repulsive force. Accordingly, since the first magnet 124 and the second magnet 125 are not fixed with the fixing plate 131 therebetween, the first magnet 124 may flow in contact with the fixing plate 131. Thus, the second magnet 125 is spaced apart from the fixing plate 131, the first magnet 124, the second magnet 125, the support shaft 123, the first plate 121, 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 the 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 may include a plurality of display devices 100 even when the wall surface fixing parts 130 of the plurality of display devices 100 are fixed to the wall surface parts 200. Since the spacing and distortion 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 when the wall surface fixing part 130 of the plurality of display devices 100 is fixed to the wall surface part 200, since fine distortion or spacing between the plurality of display devices 100 can be easily adjusted, multiple display The boundary area between the devices 100 can be minimized, and the quality of the image displayed on the tiling display device 1000 can be improved.
