Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tiling display device,

The present invention relates to a tiling display device and a tiling device for manufacturing the same.

As the information society has developed, demands for display devices have been increasing in various forms. Recently, in response to this demand, LCD (Liquid Crystal Display Device), OLED (Organic Light Emitting Display), Micro LED Display Device And the like are being utilized or studied.

Such flat panel display devices are used for a variety of purposes ranging from small-sized electronic apparatuses used in cellular phones to large-sized electronic apparatuses such as large-sized TVs.

On the other hand, the display device is not limited to use in a portable electronic device or a TV mainly used in an interior, and is used for various purposes. For example, it is used for various purposes such as a large electric signboard installed at the stadium to display information of a game, replay contents of a game, and a large electric signboard of a venue. However, such an electric signboard has to be made several hundreds of inches or more in size, and it is impossible to manufacture a flat display device of this size with current technology.

In order to solve such a problem, a method of manufacturing a single display device by tiling a plurality of display panels instead of manufacturing a large area flat panel display device on one substrate has been proposed. Such a display device is called a tiling display device. In such a tiling display device, a plurality of display panels are tiled at predetermined intervals to minimize an area where an image is not implemented between the display panel and the display panel, .

However, the following problems arise in such a tiling display device.

First, since a plurality of display panels are fabricated by assembling a tiling display device, when a distance between display panels is equal to or greater than a predetermined distance, a seam of a boundary area is recognized by the user.

In particular, in order to manufacture a large-area tiling display device of several hundreds of inches, the size of a tiled display panel must be relatively large. In the case of tiling such a large-area display panel, So that the distance between the display panels becomes a predetermined distance or more.

Second, it takes a lot of time to assemble and disassemble the tiling display device.

The tiling display device may be fixed at a predetermined position such as an arena at all times, but may be temporarily installed at the venue. On the other hand, the plurality of display panels are combined by a mechanical coupling device such as a screw to complete the tiling display. Therefore, in order to use as a temporary display device such as a venue, it is necessary to be able to assemble and disassemble rapidly. However, it takes a lot of time and effort to combine and disassemble a large-sized heavy display panel with a screw- There was a lot of inconvenience to use.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tiling apparatus capable of attaching and separating a display panel by a magnetic force by attaching a display panel to a magnet.

It is another object of the present invention to provide a tiling display device which can form a coupling part to be coupled with a plate on the rear surface of a display panel to align the display panel and the plate using the tiling device, .

In order to accomplish the above object, the tiling display device of the present invention comprises a first substrate having a display panel on its front surface, a second substrate facing a back surface of the first substrate, At least one pair of fastening bars disposed on the front surface of the second board, fastening projections projecting to the outside of the fastening bar, and fastening protrusions formed between the pair of fastening bars And at least one resilient member disposed. Here, the fastening protrusion is coupled to the fastening portion, and the first substrate is fixed to the second substrate.

In the present invention, the first magnet for attaching the display panel to the tiling apparatus and the second magnet for separating the display panel are provided, and the operation member is operated by holding the handle to operate the first magnet and the second magnet Attach the display panel to the tiling display and remove it. Therefore, it is possible to disassemble the tiling display device quickly and easily without any mechanical fastening such as screwing.

In the present invention, since the first engaging portion disposed on the rear surface of the display panel and the second engaging portion of the plate are inserted without any clearance, the insertion engaging portions of the first engaging portion and the second engaging portion themselves have alignment functions . Thus, the tiled display panels maintain a gap of a predetermined range, so that the tie between the display panels becomes invisible.

In the present invention, since the display panel and the plate are coupled by the integrated magnet and the coupling member, a separate coupling mechanism such as a screw is not required, and the coupling structure is simplified.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view conceptually showing an operator tiling a display panel by the tiling apparatus according to the present invention.

As shown in FIG. 1, in the present invention, the worker 100 directly tiles a plurality of display panels 110 to fabricate the tiling display device 150. That is, the worker 100 is positioned in front of the tiling display device 150 (in the direction in which the image is implemented), and each of the display panels 110 is attached to the tiling display device 150 from the front surface, ) Is tiled.

The tiling display device 150 includes a plate 154 to which a plurality of display panels 110 are tiled and a first support 156 disposed below the plate 154 to support the plate 154 from below, And a second support rod 158 disposed on the back surface of the first support plate 156 and the plate 154 to support the plate 154 from the side.

A plurality of display panels 110 are attached to the plate 154. At this time, since the plurality of display panels 110 to be tiled constitute one assembled display device, one display image must be displayed simultaneously according to a signal applied from the outside. However, the plurality of display panels 110 to be tiled are electrically separated. Although not shown in the drawing, the plate 154 is provided with various wiring and electric cables to electrically connect a plurality of display panels 110 to be tiled. In addition, a tiled display device is connected to an external host, .

The first and second supports 156 and 158 support the plate 154 to fix the tiling display 150. Although the first and second support rods 156 and 158 are formed in a pipe shape having a predetermined width and thickness, the first support rods 156 and the second support rods 158 are not limited to these shapes It may be configured in various shapes.

A plurality of wheels 159 may be provided on a lower surface of the first support base 156. When the tiling display device 150 is used as a provisional display device of the event site, the tiling display device 150 may be disposed at various positions as needed. When the tiling display device 150 is moved from one place to another, it takes a lot of time and effort to disassemble the plurality of tiled display panels 110, move them to the moving place, and assemble them again.

Accordingly, in the present invention, a moving means such as a wheel 159 is provided on the lower surface of the first support base 156, and the tiling display device 150 is moved using the moving means at a close distance, thereby enabling easy movement . If the location where the tiling display device 150 is installed is not suitable for the tiling operation, the tiling operation is performed at another place, and the manufactured tiling display device 150 is moved by the wheel 159 to a desired place Can be installed.

As will be described later, the display panel 110 is attached to the plate 154 by a magnetic force. Since the display panel 110 is assembled to the plate 154 by mechanical coupling such as a screw in the conventional tiling display apparatus 150, the operator 100 places the display panel 110 on the plate 154, The screws must be joined by a separate operation. Therefore, the operation of tiling a plurality of display panels 110 becomes extremely complicated. Furthermore, the operation of screwing the heavy display panel 110 in a state in which the display panel 110 is placed on the plate 154 can not be performed by one operator and requires at least two persons.

On the other hand, according to the present invention, since the display panel 110 is simply attached to the plate 154 by the magnetic force of the magnet, one operator can place the display panel 110 on the plate 154, When the display panel 110 is approached, the display panel 110 is attached to the plate 154 by a magnetic force without a separate fastening operation. Accordingly, the tiling operation of the display panel 110 according to the present invention becomes much simpler than the tiling operation of the conventional display panel 110, and thus the quick and simple tiling operation becomes possible.

In addition, in the present invention, a guide is formed on the rear surface of the display panel 110, so that the display panel 110 can be accurately attached to a predetermined position at all times. In the tiling display device 150, when the display panel 110 is not attached to the correct position, a region between the plurality of tiled display panels 110 is recognized by a person and a seam is generated on the screen . In order to prevent the occurrence of such seams, the display panel 110 must be accurately aligned with the alignment device. However, such an aligning apparatus is not only very expensive, but also requires a separate alignment process, so that the tiling operation is delayed and the manufacturing efficiency is lowered. Moreover, since the alignment process is performed manually by an operator, precise attachment of the display panel 110 is limited even when the alignment device is used.

In the present invention, a guide is formed on the rear surface of the display panel 110 so that the accurate display panel 110 can be attached without using a separate alignment device by using the guide when the display panel 110 is attached.

Various types of display panel 110 may be used. For example, the display panel 110 according to the present invention may be a variety of currently known flat panel display panels such as a liquid crystal display panel, an organic light emitting field display panel, a micro LED display panel, and the like.

In particular, the micro LED display panel is excellent in reliability using an inorganic material that is not an organic material as a light emitting element, and has a longer life than a liquid crystal display panel or an organic electroluminescence display panel. In addition, the micro LED display device is suitable for being applied to a very large-sized screen because it can display a high-brightness image because it has a fast lighting speed, low power consumption, strong impact resistance and excellent stability. Particularly, since the micro LED display panel has a very small size of the LED as the light emitting device, when the tiled display device is implemented using the micro LED display panel, the LED interval between adjacent panels can be arranged equal to the LED interval in the panel A zero-bezel implementation that does not substantially have a bezel region is possible.

In addition, the tiling display device 150 may be tiled on a display panel basis or on a cabinet basis in which a plurality of display panels are assembled. Such a cabinet unit will be described with reference to FIGS. 2 and 3. FIG.

2 is a view showing a plurality of display panels 110 and a cabinet 111 constituting the tiling display device 150. As shown in FIG.

As shown in FIG. 2, the tiling display 150 is formed by tiling a plurality of cabinets 111, and the cabinets 111 are formed by assembling a plurality of display panels 110.

As described above, in the present invention, the tiling display device 150 can be manufactured by tiling the cabinet 111 instead of directly assembling the display panel 110, for the following reason.

The unit price of the display panel 110 varies depending on the area. For example, compared to the manufacturing cost of making 20 inches, manufacturing 40 inches consumes more than just 20 inches. Further, the quality of the display panel may be deteriorated by manufacturing the display panel with a large area. Therefore, in order to manufacture the tiling display device 150 at a minimum cost, it is economical to manufacture the display panel 110 having a size that can be manufactured with a minimum cost and then tile the same.

Since the plurality of display panels 110 are tiled in the tiling display device 150, the display device 150 to which the display panel 110 is attached must be provided with a fastening structure for tiling, The panel 110 also has a fastening structure, and the display panel 110 is tiled by the coupling structure of the display device 150 and the display panel 110.

 The tiling operation of the display panel 110 is performed manually by the operator. Therefore, when a large number of display panels 110 are tiled, the fastening structure of the display panel 110 and the plate 154 of the tiling display device 150 becomes complicated and the operation time becomes long.

In other words, when the display panel 110 having a large size is tiled, the manufacturing cost of the display panel 110 is increased, and when the display panel 110 having a small size is tiled, the tiling cost is increased. In the present invention, the manufacturing cost of the display panel 110 is minimized, and the cost of tiling the display panel 110 is minimized, thereby minimizing the manufacturing cost of the tiling display device 150. To this end, in the present invention, the display panel 110 is fabricated in a size consuming the least manufacturing cost, and the plurality of display panels 110 manufactured are assembled into a cabinet 111 unit by a relatively simple assembling device And then tiles the assembled cabinet 111, thereby minimizing the manufacturing cost of the tiling display device 150.

3A is an exploded perspective view showing an assembling member 115 for assembling a plurality of display panels 110 and FIG. 3B is an exploded perspective view showing a cabinet connecting part 115b in which a plurality of display panels 110 are assembled by the assembling member 115, Fig.

3A, the assembly member 115 includes a housing 115a for housing and fixing a plurality of display panels 110, and a plurality of display panels 110 housed in the housing 115a And a cabinet connecting portion 115b.

As shown in FIG. 3B, the plurality of display panels 110 are assembled into the cabinet 111 by the cabinet engaging portion 115b. In this case, four display panels 110 are assembled to form a unit cabinet 111 of a 2 × 2 structure. However, the present invention is not limited thereto, but nine or more display panels 110 may be assembled to form a 3 × 3 or more The unit cabinet 111 may be formed.

The unit cabinet 111 or the display panel 110 configured as described above is attached to the tiling display device 150 by a tiling device.

Hereinafter, a tiling apparatus according to the present invention will be described in detail. Here, the tiling apparatus tiles in units of a cabinet or a display panel. Hereinafter, a tiling apparatus for tiling a display panel unit will be described for convenience of explanation.

4 is a view showing a tiling apparatus 120 for tiling the display panel 110 according to the present invention.

4, in the tiling apparatus 120 according to the present invention, when the operator attaches the tiling apparatus 120 in a state where the front surface of the display panel 110 is attached by the magnetic force, The display panel 110 is moved to the tiling display device 150 by moving the display panel 110 to the front surface of the display panel 110 and attaching the display panel 110 to the plate 154 and then separating the tiling device 120 from the display panel 110 Tiles.

The plate 154 may be a case constituting a display device of a large size such as a large TV, or may be a mobile case for forming a mobile electronic signboard or the like. When the display device 150 is formed on the wall surface, the plate 154 may be an engaging plate formed on the wall surface or a wall surface itself (or a part of the wall surface).

The tiling apparatus 120 includes a frame 121 that forms a skeleton, a first magnet 135 that is disposed at a rectangular corner of the frame 121 to attract and fix the display panel 110, A second magnet 137 for separating the display panel 110 attached to the plate 154 by applying a repulsive force to the plate 154 of the tiling display device 150 or the tilting display device 150, A handle 123 disposed at a lower portion of the handle 123 and adapted to move the first magnet 135 according to an operation of the operator so that the plate 123 of the tiling display 150 A first actuating member 125 which separates the tiling apparatus 120 from the display panel 110 attached to the handle 154 and a second actuating member 125 which is disposed on one side of the upper side of the handle 123, 137 to move the display panel 110 attached to the plate 154 of the tiling display device 150, By separating from the plate 154 it consists of a tiled display panel 110 to the second operating member 127 for removable from the tiled display (150).

The frame 121 is disposed in the transverse direction, the longitudinal direction, and the diagonal direction about the center base, and is coupled to the pair of support bars 122 on both sides. The supporting bar 122 extends in the longitudinal direction in the left and right regions of the frame 121, and a part of the center thereof protrudes upward and is engaged with the handle 123.

A first pressure bar 126 is disposed under each of the support bars 122. The first pressure bar 126 extends in the longitudinal direction in the lower region of the support bar 122 in the same manner as the support bar 122 and a part of the central region is protruded to engage with the first actuating member 125. The upper and lower ends of the first pressure bar 126 are coupled to the first magnet 135.

The first operating member 125 may be spaced apart from the lower portion of the handle 123 by a predetermined distance so that the user may grip the handle 123 when the operator grips the handle 123. As shown in the figure, a plurality of grooves are formed in the first actuating member 125 so that the operator's finger is positioned thereon, so that the operator's finger can be prevented from sliding when the first actuating member 125 is operated. However, the first actuating member 125 is not limited to the illustrated shape, but may be formed in various shapes.

The first pressure bar 126 transfers the motion of the first actuating member 125 to the first magnet 135. That is, when the operator grips the handle 123, when the user fingers the finger, the first operating member 125 is raised toward the handle 123 (moves away from the display panel 110) The first pressure bar 126 coupled with the operating member 125 also moves upward (in a direction away from the display panel 110). The first magnet 135 coupled to both ends of the first pressure bar 126 moves in a direction away from the display panel 110 and moves to the first magnet 135, Is separated from the display panel (110).

A spring 129 may be disposed between the support member 122 and the first pressure bar 126 to restore the first pressure bar 126 to its original position after operation of the first actuating member 125 have.

A second pressure bar 128 is disposed below the support bar 122. The second pressure bar 128 extends along the longitudinal direction at both sides of the support frame 121, and a part of the central region is protruded. At this time, the upper surface of the protruded central region comes into contact with the lower surface of the handle 123, and a part of the center of the handle 123 and the second pressure bar 128 forms a bar in contact with each other. Therefore, when the operator holds the handle 123, the central region of the second pressure bar 128 and the grip 123 which are in contact with each other are simultaneously held. The second pressure bar 128 is formed to be thinner than the groove so that the central region of the second pressure bar 128 is formed in the groove of the lower surface of the handle 123 It may be stored.

A second actuating member 127 is formed on one side of the protruded region of the second pressure bar 128. The second actuating member 127 is connected to the second magnet 137 via the second pressure bar 128. The second actuating member 127 may protrude upward from the grip 123 at a predetermined height so as to be operated by the thumb of the operator when the operator grips the grip 123.

The second pressure bar 128 transfers the motion of the second actuating member 127 to the second magnet 137. That is, when the operator holds the handle 123 and pushes the thumb in the downward direction to operate the second operation member 127, the second operation member 127 moves downward (that is, And the first pressure bar 128 coupled with the second actuating member 127 is also moved in a direction to be closer to the display panel 110. [ As the first pressure bar 128 moves, the second magnet 137 coupled to both ends of the second pressure bar 128 also moves toward the surface of the display panel 110. [

The first magnet 135 and the second magnet 137 are disposed at four corners of the tiling apparatus 120 and are respectively coupled to the first pressure bar 126 and the second pressure bar 128, And moves as the member 125 and the second actuating member 127 are operated.

The first magnet 135 is for attracting the display panel 110 to the tiling apparatus 120 and may have a circular ring shape having a predetermined width and diameter. However, the first magnet 135 is not limited to this shape, And can be configured in various shapes as well.

Since the first magnet 135 moves with the display panel 110 attached thereto, the magnitude and size of the magnetic force of the first magnet 135 are determined according to the size and weight of the display panel 110 to be tiled It will be possible.

The second magnet 137 is mainly used for separating the display panel 110 adsorbed to the tiling device 120 and is disposed at four corners of the tiling device 120. The second magnet 137 may have a circular or polygonal shape having a predetermined diameter. However, the second magnet 137 may have various shapes such as a ring shape and the like. The second magnet 137 may be disposed in the ring-shaped interior of the ring-shaped first magnet 135.

Since the second magnet 137 separates the display panel 110 attached to the tiling display device 150 rather than attaching the display panel 110 to the first magnet 137, May be smaller than the magnetic force of the first magnet 135. The second magnet 137 may be disposed on the inner side of the first magnet 135 in a circular ring shape having a smaller diameter than the first magnet 135.

The first magnet 135 and the second magnet 137 are driven by operating the first actuating member 125 and the second actuating member 127 to attach the display panel 110 to the tiling apparatus 120 The display panel 110 is disconnected from the tiling display device 150. [

Figs. 5A to 5C are diagrams showing that the first magnet 135 and the second magnet 137 are driven as the first actuating member 125 and the second actuating member 127 are operated.

Since the first operation member 125 and the second operation member 127 are not operated in a state where the display panel 110 is attached to the tiling apparatus 120 as shown in FIG. 110 are attached to the first magnet 135 so that the display panel 110 is fixed to the tiling device 120. In this state, the operator holds the handle 123 and moves the tiling apparatus 120 to which the display panel 110 is attached to the front of the tiling display apparatus 150.

5B, when the operator operates the first operation member 125 in a state where the display panel 110 is attached to the tiling display device 150, the first operation member 125 moves in the upward direction The first pressure bar 126 connected to the first actuating member 125 moves in a direction away from the display panel 110. In addition, The first magnet 135 coupled with the first pressure bar 126 also moves in a direction away from the display panel 110 so that the first magnet 135 is separated from the display panel 110.

That is, since the tiling device 120 is detached from the display panel 110 in a state where the display panel 110 is attached to the tiling display device 150, the tiling device 110 can be operated in accordance with the operation of the first operation member 125, The display panel 110 attached to the tiling display device 150 is tiled.

The operator can tile all the display panels 110 to the tiling display 150 by repeating the above process after attaching the other display panel 110 to the separated tiling device 120.

The tiling device 120 is disposed on the front surface of the display panel 150 tiled in the tiling display device 150 so that the front surface of the display panel 15 is tilted by the first magnet 135 When the second actuating member 127 is operated, the second actuating member 127 moves downward (in the direction of approaching the display panel) while being engaged with the second actuating member 127 The second pressure bar 128 is moved in a direction toward the display panel 110. [

Also, the second magnet 137 coupled with the second pressure bar 128 is also moved toward the display panel 110 side. As the second magnet 137 approaches the display panel 110, the attraction force between the second magnet 137 and the magnet provided on the display panel 110 or the repulsive force with the magnet provided on the tiling display device 150 The magnetic force of the tiling device 120 with respect to the display panel 110 exceeds the magnetic force of the tiling display device 150. [ In this state, when the tiling apparatus 120 is moved away from the tiling display apparatus 150, the display panel 110 is detached from the tiling display apparatus 150 while being attached to the tiling apparatus 120, (110) is completely separated from the tiling display device (150).

As described above, in the tiling apparatus 120 according to the present invention, when the operator tiles the display panel 110 from the front of the tiling display 150 in a state where the display panel 110 is attached by the first magnet 135 So that the display panel 110 can be easily tiled.

In the present invention, since the display panel 110 tiled in the tiling display device 150 is separated by the magnetic force of the second magnet 137, compared with the mechanical separation method of separating the display panel 110 from a tool or the like The display panel 110 can be easily separated.

In the present invention, by operating the first magnet 135 and the second magnet 137 by operating the first operating member 125 and the second operating member 127 provided on the handle, the display panel 110 The tiling display device 150 can be easily attached and detached.

In the tiling apparatus 120 having the above-described structure, the display panel 110 can be tiled by moving the display panel 110 to the tiling display unit 150 with the magnetic force of the magnet attached to the display panel 110 . The display panel 110 is tiled to the tiling display device 150 by a magnetic force. In addition, the display panel 110 is provided with a guide so that the display panel 110 is always disposed in a predetermined area of the tiling display device 150 when the display panel 110 is tiled, thereby preventing defects due to misalignment. In addition, the guide not only functions to align the display panel 110 and the tiling display device 150 during tiling, but also attaches the actual display panel 110 to the tiling display device 150.

Hereinafter, a display panel and a tiling display device which are tiled by the tiling device 120 of the present invention will be described in detail with reference to the accompanying drawings.

6 is a view showing the structure of a tiling display device 150 according to the first embodiment of the present invention. 1, only the coupling structure in which the display panel 110 and the plate 154 of the tiling display 150 are coupled to each other is specifically shown in the drawing.

The engaging member 188 may be formed of a synthetic resin. The diameter of the cylindrical inner space of the main body 162 of the first coupling portion 160 is set to be substantially equal to the outer diameter of the guide portion 182 of the second coupling portion 180, So that the display panel 110 is always tiled at the set position.

Meanwhile, the body 162 of the first coupling portion 160 is not limited to the cylindrical shape of the cylinder, but may be applied to various shapes such as a polygonal cylinder shape. The guide 182 of the second engaging part 180 inserted into the main body 162 may also be applied to various shapes such as a polygonal cylinder like the main body 162.

The first engaging portion 160 and the second engaging portion 180 engaged with the engaging groove 164 of the first engaging portion 160 are separated from the engaging member 188 of the second engaging portion 180, It functions as a stopper.

The engaging member 188 is disposed in the through hole formed in the guide 182 and is formed to move up and down through the through hole. The coupling member 188 may be in the form of a plurality of balls arranged along the circumference of the guide 182.

The moving member 185 of the second engaging part 180 is formed in a piston shape and inserted into the guide 182 and a receiving groove 185a is formed in the central area along the circumference. At this time, the receiving groove 185a corresponds to the engaging member 188, and may be formed continuously along the circumference or may be a set size groove formed at a corresponding position of the ball-shaped engaging member 188. [

The moving member 185 is movably disposed in the guide 182 and is always restored to the set position by the elasticity of the elastic member 186. The first tiling magnet 184 is provided at the tip of the moving member 185 and moves left and right together with the moving member 185. The first tilting magnet 184 may be attached to the distal end of the moving member 185 and may be integrally formed with the moving member 185 so that the moving member 185 The tip region may be formed of a magnet.

The moving member 185 moves the receiving groove 185a and the coupling member 188 moves up and down the guide 182 by moving the receiving groove 185a. The thickness of the engaging member 188 is greater than the depth of the through hole formed in the guide 182 so that the engaging member 188 is positioned in the receiving groove 185a or in the guide 182 depending on the position of the moving member 185, Through holes of the base plate.

In this tiling display apparatus, after the display panel 110 is attached to the plate 154 by the first tiling magnet 184, the magnetic force of the first tiling magnet 184 and the coupling force of the coupling member 188 The display panel 110 is tiled. Further, the display panel 110 is separated from the tiled display by the first tiling magnet 184.

7A to 7G are views showing a method of tiling the display panel 110 according to the first embodiment of the present invention to the plate 154 of the tiling display device 150 by the tiling device.

7A, when the front surface of the display panel 110 is attached to the tiling device 120 by the first magnet 135 of the tiling device 120 according to the present invention, (110) is positioned in front of the plate (154) of the tiling display.

When the display panel 110 fixed to the tiling apparatus 120 is moved to the plate 154 in this state, the first engaging portion 160 is moved along the second engaging portion 180 as shown in FIG. The second engaging portion 180 is inserted into the first engaging portion 160 while the engaging member 188 protruding to the upper portion of the guide 182 by the moving member 185 is engaged with the first engaging portion 160, The movement of the first engaging portion 160 is stopped. That is, only a part of the first coupling portion 160 and the second coupling portion 180 are coupled to each other, so that the first tiling magnet 184 and the moving member 185 are separated from the display panel 110 by a certain distance.

When the second magnet 137 is moved toward the display panel 110 by operating the second actuating member 127 of the tiling apparatus 120, 7C, the first tiling magnet 184 and the moving member 185 are elastically deformed, as shown in Fig. 7C, because the region where the first tilting magnet 184 and the region facing the display panel 110 of the first tilting magnet 184 have the same polarity And the receiving groove 185a of the moving member 185 is moved to the opposite side of the elasticity of the member 188, that is, to the side of the plate 154, is located at the same position as the engaging member 188. [

Subsequently, when the operator further pushes the tiling device 120 toward the plate 154 side to move the first engaging portion 160 toward the plate 154, the engaging member 188 is moved to the moving member And the engaging groove 164 of the first engaging portion 160 is located at a position where the engaging member 188 is disposed.

Thus, as shown in FIG. 7E, the first tiling magnet 184 contacts the surface of the display panel 110. Since the display panel 110 is housed in a back cover made of metal, the first tiling magnet 184 applies a force to the back cover on the back surface of the display panel 110 to fix the display panel 110 The engaging member 188 positioned in the receiving groove 185a protrudes from the guide 182 and is engaged with the engaging groove 164 of the first engaging portion 160. [ In addition, when the display panel 110 is assembled in a cabinet unit and then tiled, a first tiling magnet 184 attracts the display panel 110 by applying a force to a cabinet engaging portion made of metal or containing metal .

As described above, in the tiling display apparatus of this embodiment, since the display panel 110 is provided with the magnet and the coupling member 188 on the plate 154 of the tiling display apparatus, the display panel 110 can be tiled without any mechanical operation such as assembling screws for tiling , The operator can tile the display panel 110 by automatically attaching the display panel 110 fixed to the tiling device to the plate 154 at the front side of the tiling display device. Therefore, tiling of the display panel 154 can be performed quickly and easily by a small number of operators.

In addition, in the present invention, the display panel 110 tiled in the tiling display device can be separated by the tiling device 120. Referring to FIGS. 8A to 8C, the tiling display device according to the first embodiment of the present invention The separation method will be described.

8A, when the operator is positioned on the front side of the tiling display device in which the display panel 110 is tiled by the first coupling portion 160 and the second coupling portion 180, the tiling device 120, The second magnet 137 is moved toward the display panel 110 by operating the second actuating member 127 of the tilting apparatus 120 while the second magnet 137 is attached to the display panel 110, The moving member 185 moves toward the plate 154 due to the repulsive force of the first tiling magnet 184 disposed at the tip of the moving member 185 of the second engaging portion 180.

As shown in FIG. 8B, as the first tiling magnet 184 moves, the adhesive force of the display panel 110 by the magnetic force of the first tiling magnet 184 is removed. As the moving member 185 moves, the receiving groove 185a of the moving member 185 is positioned at the same position as the engaging member 188, and the engaging member 188 is accommodated in the receiving groove 185a The engagement of the engaging member 188 with the engaging groove 164 of the first engaging portion 160 is released.

Thereafter, the tiling device 120 is moved away from the plate 154 in a state in which the engagement of the engagement member 188 and the engagement groove 164 of the first engagement portion 160 is released, The display panel 110 becomes detachable from the tiling display device.
