Description

TILING DISPLAY DEVICE AND APPARATUS FOR TILING THEREOF

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

As the information society develops, the demand for display devices is increasing in various forms. In response to this, in recent years, LCD (Liquid Crystal Display Device), OLED (Organic Light Emitting Display), and Micro LED Display Device Various flat panel display devices such as, etc. are being utilized or studied.

Such flat panel display devices are used for various purposes, from small-sized electronic devices used in cell phones and the like to large-sized electronic devices such as large-sized TVs.

On the other hand, the display device is not limited to the use of portable electronic devices or TVs mainly used indoors, but is used for various purposes. For example, it is installed in a stadium and used for various purposes, such as a large electronic display board that displays information about a game and replays and shows the content of the game, or a large electronic display board at an event venue. However, such an electric sign has to be manufactured to have a size of several hundred inches or more, and it is impossible to manufacture a flat panel display of this size with current technology.

In order to solve this problem, a method of manufacturing a single display device by tiling a plurality of display panels rather than manufacturing a large-area flat panel display device on a single substrate has been proposed. Such a display device is called a tiling display device. In such a tiling display device, a single image without dividing lines can be realized by minimizing an area in which an image is not realized between the display panel and the display panel by tiling a plurality of display panels at set intervals. be able to

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

First, since the tiling display device is manufactured by assembling a plurality of display panels, when the distance between the display panels is greater than or equal to a set distance, a problem occurs in that a seam of the boundary area is recognized by the user.

In particular, in order to manufacture a large-area tiling display device of several hundred inches, the size of a tiled display panel must also be relatively large. The distance between the display panels becomes greater than the set distance.

Second, a lot of time is consumed in assembling and disassembling the tiling display device.

The tiling display device may be always fixed at a predetermined location, such as a stadium, or may be temporarily installed and used at an event venue. Meanwhile, the plurality of display panels are coupled by a mechanical coupling device such as a screw to complete the tiling display device. Therefore, in order to use it as a temporary display device such as an event hall, quick assembly and disassembly must be possible. consumed), there was a lot of inconvenience in use.

The present invention has been made in view of the above, and an object of the present invention is to provide a tiling device capable of attaching a display panel with a magnet and attaching and detaching the display panel with magnetic force.

Another object of the present invention is to provide a tiling display device capable of aligning a display panel and a plate by using the tiling device by configuring a coupling part coupled to a plate on the rear surface of the display panel, and at the same time simply coupling the display panel and the plate. will do

In order to achieve the above object of the present invention, a tiling display device of the present invention includes a plurality of first frames supporting one or more display panels, a second frame coupled to the plurality of first frames, and the first frame a first protrusion protruding on the upper surface to face the second frame, a second protrusion protruding from the second frame toward the first frame, a first magnet disposed on the first frame, and the second and a second magnet disposed on the frame. Here, by coupling the first protrusion and the second protrusion to each other, the first frame is fixed to the second frame.

In the present invention, a first magnet for attaching a display panel to a tiling device and a second magnet for separating the display panel are provided, and the first magnet and the second magnet are operated by operating the operation member while holding the handle. Attach the display panel to the tiling display device and remove it. Accordingly, it is possible to quickly and easily disassemble the tiling display device without a separate mechanical fastening such as screw fastening.

In addition, in the present invention, since the coupling of the first coupling part disposed on the rear surface of the display panel and the second coupling part of the plate is inserted and coupled without a gap, the insertion coupling itself of the first coupling part and the second coupling part has an alignment function. . Accordingly, the tiled display panels maintain an interval of a set range from each other, so that the seam between the display panels is not visible.

Further, in the present invention, since the display panel and the plate are coupled by an integrated magnet and a coupling member, a separate coupling mechanism such as a screw is not required, thereby simplifying the coupling structure.

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

1 is a diagram conceptually illustrating that an operator tiles a display panel by a tiling apparatus according to the present invention.

As shown in FIG. 1 , in the present invention, an operator 100 directly tiles a plurality of display panels 110 to manufacture a tiling display device 150 . That is, the operator 100 is positioned in front of the tiling display device 150 (in the direction in which an image is implemented) and attaches each display panel 110 to the tiling display device 150 from the front, thereby forming the plurality of display panels 110 . ) is tiled.

The tiling display device 150 includes a plate 154 on 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 the bottom. and a second support 158 disposed at a set angle on the rear surface of the first support 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 . In this case, since the plurality of tiled display panels 110 constitute one assembled display device, they must be simultaneously displayed according to a signal applied from the outside to realize one image. However, the plurality of tiled display panels 110 are electrically separated. Although not shown in the drawings, various wires and electric cables are disposed on the plate 154 to electrically connect a plurality of tiled display panels 110 as well as connect the tiled display device to an external host to transmit signals from the outside. is authorized

The first supporter 156 and the second supporter 158 support the plate 154 to fix the tiling display device 150 . In the drawings, the first support 156 and the second support 158 are configured in a pipe shape of a certain width and thickness, but the first support 156 and the second support 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 156 . When the tiling display device 150 is used as a temporary display device in an event hall, the tiling display device 150 may be arranged in various positions as needed. When the tiling display device 150 is moved from one place to another, a lot of time and effort are required if the plurality of tiled display panels 110 are disassembled and then moved to the moving place and reassembled.

Accordingly, in the present invention, a moving means such as a wheel 159 is provided on the lower surface of the first support 156 to move the tiling display device 150 by using the moving means at a short distance, so that easy movement is possible. . In addition, when the place 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 wheels 159 to a desired place. can be installed

Although described later, the display panel 110 is attached to the plate 154 by magnetic force. In the conventional tiling display device 150 , the display panel 110 is assembled to the plate 154 by mechanical coupling such as screws. The screws must be joined by a separate operation. Accordingly, the operation of tiling the plurality of display panels 110 becomes very complicated. Furthermore, screwing the heavy display panel 110 on the plate 154 is impossible with one worker and requires at least two people.

On the other hand, in the present invention, since the display panel 110 is simply attached to the plate 154 by the magnetic force of a magnet, one operator places the display panel 110 in front of the plate 154 and attaches it to the plate 154 . When the display panel 110 is approached, the display panel 110 is attached to the plate 154 by magnetic force without a separate fastening operation. Accordingly, the tiling operation of the display panel 110 according to the present invention is much simpler than the tiling operation of the conventional display panel 110 , so that a quick and simple tiling operation is 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 always be accurately attached to a set position. In the tiling display device 150, when the display panel 110 is not attached to the correct position, the area 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 such shims from occurring, it is necessary to attach the display panel 110 in a state in which the display panel 110 is accurately aligned by the alignment device. However, since such an alignment device is very expensive and requires a separate alignment process, the tiling operation is delayed and manufacturing efficiency is lowered. Moreover, since the attachment process after alignment is performed manually by an operator, there is a limit to the accurate attachment of the display panel 110 even using an alignment device.

In the present invention, by forming a guide on the rear surface of the display panel 110 and using the guide when attaching the display panel 110 , it is possible to accurately attach the display panel 110 without using a separate alignment device.

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

In particular, the micro LED display panel uses an inorganic material rather than an organic material as a light emitting device, so it has excellent reliability and has a longer lifespan compared to a liquid crystal display panel or an organic light emitting display panel. In addition, the micro LED display device has a fast lighting speed, low power consumption, excellent stability due to strong impact resistance, and is suitable for being applied to a very large screen because it can display a high-brightness image. In particular, since the size of the LED, which is a light emitting device, is very small in a micro LED display panel, when a tiling display is implemented using a micro LED display panel, the LED spacing between adjacent panels can be arranged to be the same as the LED spacing in the panel. Therefore, it is possible to implement a zero bezel in which there is substantially no bezel area.

Also, the tiling display device 150 may be tiled in units of display panels or may be tiled in units of cabinets in which a plurality of display panels are assembled. These cabinet units will be described with reference to FIGS. 2 and 3 .

FIG. 2 is a diagram illustrating a plurality of display panels 110 and a cabinet 111 constituting the tiling display device 150 .

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

As described above, in the present invention, the tiling display device 150 may be manufactured by tiling the cabinet 111 rather than directly assembling the display panel 110 , for the following reasons.

The unit price of the display panel 110 varies according to an area. For example, compared to the manufacturing cost of manufacturing 20 inches, when manufacturing 40 inches, the manufacturing cost is not simply twice that of 20 inches, but more than the manufacturing cost is consumed. Also, as the display panel is manufactured with a large area, the quality of the display panel may be deteriorated. Therefore, in order to manufacture the tiling display device 150 at the minimum cost, it is economical to manufacture the display panel 110 of a size that can be manufactured at the minimum cost and then tile the display panel 110 .

On the other hand, 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 not only have a fastening structure for tiling but also a display to be attached. A fastening structure is also provided on the panel 110 , and the display panel 110 is tiled by coupling the fastening structure between the display device 150 and the display panel 110 .

In addition, the tiling operation of the display panel 110 is performed manually by an operator. Accordingly, when a large number of display panels 110 are tiled, the coupling structure between the display panel 110 and the plate 154 of the tiling display device 150 becomes complicated and the working time becomes long.

In other words, when the display panel 110 of a wide size is tiled, the manufacturing cost of the display panel 110 increases, and when the display panel 110 of a small size is tiled, the tiling cost increases. In the present invention, the manufacturing cost of the tiling display device 150 is minimized by minimizing the manufacturing cost of the display panel 110 and also minimizing the tiling cost of the display panel 110 . To this end, in the present invention, the display panel 110 is manufactured in a size that consumes the least manufacturing cost, and a plurality of manufactured display panels 110 are assembled in a cabinet 111 unit by an assembly device having a relatively simple structure. Then, by tiling the assembled cabinet 111 , the manufacturing cost of the tiling display device 150 is minimized.

3A is an exploded perspective view illustrating an assembly member 115 for assembling a plurality of display panels 110 , and FIG. 3B is a cabinet fastening part 115b to which a plurality of display panels 110 are assembled by the assembly member 115 . is a rear view of

As shown in FIG. 3A , the assembly member 115 assembles a housing 115a for receiving and fixing a plurality of display panels 110 and a plurality of display panels 110 accommodated in the housing 115a. and a cabinet fastening part 115b.

As shown in FIG. 3B , the plurality of display panels 110 are assembled in units of the cabinet 111 by the cabinet fastening part 115b. In this case, in the drawing, four display panels 110 are assembled to form a unit cabinet 111 having a 2×2 structure, but the present invention is not limited thereto, and nine or more display panels 110 are assembled to form a 3×3 or more A 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 the tiling device.

Hereinafter, a tiling apparatus according to the present invention will be described in detail. In this case, although the tiling apparatus tiles in units of cabinets or display panels, a tiling apparatus that tiles in units of display panels will be described below for convenience of description.

4 is a diagram illustrating a tiling device 120 for tiling the display panel 110 according to the present invention.

As shown in FIG. 4 , in the tiling device 120 according to the present invention, a worker holds the tiling device 120 while attaching the front surface of the display panel 110 by magnetic force to the plate of the tiling display device 150 . (154) After moving to the front and attaching the display panel 110 to the plate 154, the tiling device 120 is separated from the display panel 110 to attach the display panel 110 to the tiling display device 150. can be tiled.

The plate 154 may be a case constituting a large-size display device such as a large-sized TV, or may be a movable case forming a movable electric sign board or the like. Also, when the display device 150 is formed on a wall surface, the plate 154 may be a coupling plate formed on the wall surface or the wall surface itself (or a part of the wall surface).

The tiling device 120 includes a frame 121 forming a skeleton, a first magnet 135 disposed at a rectangular corner of the frame 121 to adsorb and fix the display panel 110 , and a display panel. (110) or 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, and both sides of the frame 121 The plate of the tiling display device 150 by moving the first magnet 135 formed in each of the handles 123 formed in each of the handles 123 for holding and tiling by the operator, and the first magnet 135 disposed under the handle 123 and operated by the operator. A first operation member 125 for separating the tiling device 120 from the display panel 110 attached to 154, and a second magnet ( 137) to separate the display panel 110 attached to the plate 154 of the tiling display device 150 from the plate 154 to detach the tiled display panel 110 from the tiling display device 150. It is composed of a second operation member (127).

The frame 121 is arranged in a horizontal direction, a vertical direction, and a diagonal direction with respect to the central base, and is coupled to a pair of support bars 122 on both sides. The support bar 122 is formed to extend in the vertical direction from the left and right regions of the frame 121 , and a central portion of the support bar 122 protrudes upward and is coupled to 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 same manner as the support bar 122 in the lower region of the support bar 122 , and a part of the central region protrudes to be coupled to the first operation member 125 . In addition, upper and lower ends of the first pressure bar 126 are coupled to the first magnet 135 .

The first operation member 125 may be disposed to be spaced apart from the lower portion of the handle 123 by a predetermined distance, so that a finger portion may be caught when the operator holds the handle 123 . As shown in the drawing, a plurality of grooves are formed in the first operation member 125 to place the operator's fingers, thereby preventing the operator's fingers from sliding when the first operation member 125 is operated. However, the first operation member 125 is not limited to the illustrated shape, but may be configured in various shapes.

The first pressure bar 126 transmits the motion of the first operation member 125 to the first magnet 135 . That is, when the operator pinches the finger while holding the handle 123 , the first operation member 125 rises toward the handle 123 (moves away from the display panel 110 ), and the first operation member 125 moves away from the display panel 110 . The first pressure bar 126 coupled to the operation member 125 also moves upward (a direction away from the display panel 110 ). In addition, as the first pressure bar 126 moves, the first magnets 135 coupled to both ends of the first pressure bar 126 also move away from the display panel 110 to move the first magnet 135 . This is separated from the display panel 110 .

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

A second pressure bar 128 is disposed under the support bar 122 . The second pressure bar 128 extends along the longitudinal direction from both sides of the support frame 121, and a portion of the central region protrudes. At this time, the upper surface of the protruding central region is in contact with the lower surface of the handle 123 , and a partial region of the center of the handle 123 and the second pressure bar 128 is in contact with each other to form a single bar. Therefore, when the operator holds the handle 123 , the center area of the handle 123 and the second pressure bar 128 that are in contact with each other is simultaneously held. In addition, a groove is formed on the lower surface of the handle 123 and the second pressure bar 128 is formed to have a thinner thickness than the groove, so that the central region of the second pressure bar 128 is in the groove on the lower surface of the handle 123 . may be stored.

A second operation member 127 is formed on one side of the protruding area of the second pressure bar 128 . The second operation member 127 is connected to the second magnet 137 through the second pressure bar 128 . The second operation member 127 may be formed to protrude upward from the handle 123 at a predetermined height and be operated by the operator's thumb when the operator holds the handle 123 .

The second pressure bar 128 transmits the motion of the second operation member 127 to the second magnet 137 . That is, when the operator operates the second operation member 127 by extending and pushing the thumb downward while holding the handle 123 , the second operation member 127 moves downward (ie, the display panel 110 ). ), and the first pressure bar 128 coupled to the second operation member 127 also moves in a direction closer to the display panel 110 . In addition, as the first pressure bar 128 moves, the second magnets 137 coupled to both ends of the second pressure bar 128 also move toward the surface of the display panel 110 .

The first magnet 135 and the second magnet 137 are respectively disposed at the four corners of the tiling device 120 and are coupled to the first pressure bar 126 and the second pressure bar 128, respectively, for the first operation The member 125 and the second operation member 127 move as they operate.

The first magnet 135 is for adsorbing the display panel 110 to the tiling device 120 , and may be configured in a circular ring shape having a set width and diameter, but is not limited to this shape, and may be formed in a rectangular shape and a rectangular shape. It can be configured in various shapes.

Since the first magnet 135 moves while the display panel 110 is attached, the strength or size of the magnetic force of the first magnet 135 may be determined according to the size and weight of the tiled display panel 110 . will be able

The second magnet 137 is mainly used to separate the display panel 110 adsorbed to the tiling device 120 , and is disposed at a corner of the tiling device 120 . The second magnet 137 may be configured in a circular shape having a set diameter or a polygonal shape having a set size, but is not limited to this shape and may be configured in various shapes such as a ring shape. The second magnet 137 may be disposed inside a ring shape of the ring shape first magnet 135 .

Since the second magnet 137 does not move by attaching the display panel 110 , but simply separating the display panel 110 attached to the tiling display device 150 , the magnetic force of the second magnet 137 . may be smaller than the magnetic force of the first magnet 135 . The second magnet 137 may have a circular ring shape having a smaller diameter than that of the first magnet 135 , and may be disposed inside the first magnet 135 .

The first and second magnets 135 and 137 are driven by manipulating the first and second operating members 125 and 127 to attach the display panel 110 to the tiling device 120 or The display panel 110 is separated from the tiling display device 150 .

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

As shown in FIG. 5A , since the first operation member 125 and the second operation member 127 are not operated when the display panel 110 is attached to the tiling device 120, the display panel ( 110 is 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 device 120 to which the display panel 110 is attached to the front of the tiling display device 150 .

As shown in FIG. 5B , when the operator operates the first operating member 125 while the display panel 110 is attached to the tiling display device 150 , the first operating member 125 moves upward ( The first pressure bar 126 connected to the first operation member 125 also moves in a direction away from the display panel 110 while moving in a direction away from the display panel 110 . In addition, the first magnet 135 coupled to the first pressure bar 126 also moves 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 separated from the display panel 110 while the display panel 110 is attached to the tiling display device 150 , the tiling device 110 according to the operation of the first operation member 125 . The display panel 110 attached to the tile is tiled with the tiling display device 150 .

An operator attaches another display panel 110 using the separated tiling device 120 and then repeats the above process to tile all the display panels 110 to the tiling display device 150 .

As shown in FIG. 5C , the tiling device 120 is disposed on the front surface of the tiled display panel 150 in the tiling display device 150 , and the front surface of the display panel 15 is rotated by the first magnet 135 . In the attached state, when the second operating member 127 is operated, the second operating member 127 moves in a downward direction (a direction closer to the display panel) and is coupled with the second operating member 127 at the same time. The second pressure bar 128 also moves in a direction closer to the display panel 110 .

In addition, the second magnet 137 coupled to the second pressure bar 128 also moves toward the display panel 110 . As the second magnet 137 approaches the display panel 110 , an attraction force between the second magnet 137 and a magnet provided in the display panel 110 or a repulsive force between the second magnet 137 and a magnet provided in the tiling display device 150 . Accordingly, 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 device 120 is moved away from the tiling display device 150 , the display panel 110 moves away from the tiling display device 150 while the display panel 110 is attached to the tiling device 120 , and the display panel 110 is completely separated from the tiling display device 150 .

As described above, in the tiling device 120 according to the present invention, in a state in which the display panel 110 is attached by the first magnet 135 , an operator can tile the display panel 110 from the front of the tiling display device 150 . Therefore, it is possible to easily tile the display panel 110 .

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

In addition, in the present invention, the display panel 110 is formed by operating the first and second operating members 125 and 127 provided in the handle to operate the first and second magnets 135 and 137 . It is possible to easily attach to and detach from the tiling display device 150 .

In the tiling device 120 having the above structure, the display panel can be tiled by moving the display panel 110 to the tiling display device 150 while the display panel 110 is attached by the magnetic force of a magnet. . The display panel 110 is tiled on the tiling display device 150 by magnetic force. In addition, the display panel 110 is provided with a guide, so that when the display panel 110 is tiled, it is always disposed in a set area of the tiling display device 150 to prevent 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 performs a function of attaching the actual display panel 110 to the tiling display device 150 .

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

6 is a diagram showing the structure of a tiling display device 150 according to the first embodiment of the present invention. At this time, since the tiling display device 150 is the same as that of FIG. 1 , only the coupling structure in which the actual display panel 110 and the plate 154 of the tiling display device 150 are coupled is specifically illustrated in the drawing.

As shown in FIG. 6 , a first coupling part 160 is formed on each of the rear four corners of the display panel 110 , and a second coupling part 180 is formed on the front surface of the plate 154 of the tiling display device. . In this case, the tiling device 120 is disposed on the front surface of the display panel 110 to assemble the display panel 110 to the plate 154 in a state where the display panel 110 is fixed.

At this time, in the drawing, in order to show the coupling relationship between the first coupling part 160 and the second coupling part 180, the plate 154 is not shown, and the second coupling part 180 is fixed only in a partially enlarged cross-sectional view. Plate 154 is shown. The first coupling part 160 and the second coupling part 180 are coupled to each other to not only tile the display panel 110 to the plate 154 of the tiling display device, but also to tile the tiled display panel 110 to the plate 154 . ) is aligned with In other words, in the present invention, the second coupling part 180 is inserted and coupled in the first coupling part 160 , and the second coupling part 180 is inserted into the first coupling part 160 itself as an alignment means. will perform the function of Accordingly, in the present invention, the display panel 110 can be tiled at a set position of the plate 154 without a separate alignment device.

The first coupling part 160 is composed of a cylindrical body 162 and a coupling groove 164 formed along the circumference on the inner surface of the body 162 .

The second coupling part 180 includes a hollow cylindrical guide 182 inserted into the main body 162 of the first coupling part 160 and a moving member inserted into the guide 182 to move. 185 , a first tiling magnet 184 provided at the tip of the moving member 185 to adsorb the display panel 110 , and a spring disposed between the plate 154 and the moving member 185 . It is composed of an elastic member 186 such as, and a coupling member 188 disposed along the circumference of the guide (182). The diameter of the cylindrical inner space of the main body 162 of the first coupling part 160 is set to be substantially equal to the outer diameter of the guide part 182 of the second coupling part 180, and the first coupling part 160 Since a gap does not occur when the and the second coupling unit 180 are coupled, the display panel 110 is always tiled at a set position.

On the other hand, the body 162 of the first coupling part 160 may be applied to various shapes, such as a polygonal cylindrical shape, rather than being limited only to a cylindrical cylindrical shape. In addition, the guide 182 of the second coupling part 180 inserted into the main body 162 may also be applied to various shapes such as a polygonal cylindrical shape like the main body 162 .

The coupling member 188 of the second coupling part 180 is coupled to the coupling groove 164 of the first coupling part 160 so that the coupled first coupling part 160 and the second coupling part 180 are not separated. It functions as a stopper.

The coupling member 188 is disposed in the through hole formed in the guide 182 and is formed to move up and down of the through hole. The coupling member 188 may have a ball shape arranged in plurality along the circumference of the guide 182 .

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

The movable member 185 is movably disposed in the guide 182 , and is always restored to a 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 . At this time, the first tiling magnet 184 may be configured separately from the moving member 185 and may be attached to the front end of the moving member 185 , or may be formed integrally with the moving member 185 so as to prevent the moving member 185 from moving. The tip region may be formed of a magnet.

The receiving groove 185a is moved by the movement of the moving member 185), and the coupling member 188 moves up and down the guide 182 by the movement of the receiving groove 185a. The thickness of the coupling member 188 is greater than the depth of the through hole formed in the guide 182, and accordingly, the coupling member 188 is located in the receiving groove 185a or the guide 182 depending on the position of the moving member 185. It may be located over the through hole of

In the tiling display device having this structure, 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 are used. The display panel 110 is tiled. Also, the display panel 110 is separated from the tiling display device by the first tiling magnet 184 .

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

In this state, when the display panel 110 fixed to the tiling device 120 is moved to the plate 154 , the first coupler 160 moves along the second coupler 180 as shown in FIG. 7B . While moving, the second coupling part 180 is inserted into the first coupling part 160 , but the coupling member 188 protruding to the upper part of the guide 182 by the moving member 185 is the first coupling part 160 . In contact with the end of the body 162 of the first coupling portion 160 stops the movement. That is, only a portion of the first coupling part 160 and the second coupling part 180 is coupled, so that the first tiling magnet 184 and the moving member 185 are spaced apart from the display panel 110 by a predetermined distance.

Then, when the second magnet 137 approaches the display panel 110 by operating the second operation member 127 of the tiling device 120 , the second magnet 137 faces the display panel 110 . Since the region of the first tiling magnet 184 and the region facing the display panel 110 of the first tiling magnet 184 have the same polarity, as shown in FIG. 7C , the first tiling magnet 184 and the moving member 185 are elastic. The member 188 moves in the opposite direction to the elasticity of the member 188 , that is, toward the plate 154 , so that the receiving groove 185a of the moving member 185) is located at the same place as the coupling member 188 .

Then, when the operator further pushes the tiling device 120 toward the plate 154 to move the first coupling unit 160 toward the plate 154, the coupling member 188 moves to the moving member ( It is accommodated in the receiving groove 185a of the 185 and the coupling groove 164 of the first coupling part 160 is positioned at the place where the coupling member 188 is disposed.

Accordingly, as shown in FIG. 7E , the first tiling magnet 184 is in contact with the surface of the display panel 110 . Since the display panel 110 is accommodated in a back cover made of metal, the first tiling magnet 184 applies an attractive force to the back cover of the rear surface of the display panel 110 to fix the display panel 110 and The coupling member 188 located in the receiving groove 185a protrudes from the guide 182 and is coupled to the coupling groove 164 of the first coupling part 160 . In addition, when the display panel 110 is assembled in a cabinet unit and then tiled, the first tiling magnet 184 may adsorb the display panel 110 by applying an attractive force to a cabinet fastening part made of or including metal. be able to

As described above, in the tiling display device of this embodiment, since the display panel 110 is tiled by providing the magnet and the coupling member 188 to the plate 154 of the tiling display device, there is no mechanical manipulation such as assembly of screws for tiling. , the operator can tile the display panel 110 by simply attaching the display panel 110 fixed to the tiling device to the plate 154 from the front of the tiling display device. Accordingly, the tiling of the display panel 154 can be quickly and easily performed by a small number of workers.

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

As shown in FIG. 8B , as the first tiling magnet 184 moves, the adhesive force of the display panel 110 due to the magnetic force of the first tiling magnet 184 is removed. In addition, as the moving member 185 moves, the receiving groove 185a of the moving member 185 is located in the same place as the coupling member 188, so that the coupling member 188 is accommodated in the receiving groove 185a. The coupling between the coupling member 188 and the coupling groove 164 of the first coupling part 160 is released.

Thereafter, by moving the tiling device 120 away from the plate 154 in a state in which the coupling between the coupling member 188 and the coupling groove 164 of the first coupling part 160 is released, as shown in FIG. 8c .

When the second coupling part 180 is inserted into the part 160 , a repulsive force acts between the first tiling magnet 184 and the second tiling magnet 166 having different polarities in regions facing each other.

Accordingly, when the first coupling part 160 is pushed toward the plate 154, the moving member 185 moves to the plate 154 side, and as shown in FIG. 10B , the receiving groove of the moving member 185 ( 185a) is aligned with the engaging member 188 . At this time, the coupling member 188 is in contact with the end of the main body 162 of the moving first coupling part 160, but the coupling member 188 is accommodated in the receiving groove 185a, and the first coupling part 160 ) continues to move so that the coupling member 188 is coupled to the coupling groove 164 of the first coupling part 160 .

Subsequently, when the first coupling part 160 is pushed toward the plate 154, the first coupling part 160 and the second tiling magnet 166 at the end move toward the plate 154, but the first tiling magnet ( 184 ) and the moving member 185 do not move due to the elasticity of the elastic member 186 . Accordingly, the second tiling magnet 166 moves and the moving member 185 remains stationary, and when the second tiling magnet 166 passes the first tiling magnet 184 , the first tiling magnet 184 . ) and the repulsive force between the second tiling magnet 166 is removed (or by a repulsive force in the opposite direction), and the moving member 185 is displayed by the elasticity of the elastic member 186 as shown in FIG. 10C . Moving toward the panel 110 , the display panel 110 is attached to the first tiling magnet 184 , so that the display panel 110 is tiled on the plate 154 .

When the display panel 110 is separated from the plate 154 , as shown in FIG. 10D , the display panel 110 is attached to the tiling device 120 by the first magnet 135 . When the second magnet 137 is approached toward the display panel 110 by operating the second operating member 127 , the second magnet 137 and the first tiling magnet 184 having the same polarity as their opposite faces are formed. The first tiling magnet 184 is separated from the display panel 110 by the repulsive force and moves toward the plate 154 . At this time, the receiving groove 185a of the moving member 185 is aligned with the coupling member 188, and the coupling member 188 is accommodated in the receiving groove 185a, and the coupling member 188 and the defective groove 164 are accommodated. ) is uncoupled.

11 is a diagram illustrating a tiling display device according to a second embodiment of the present invention. In this case, descriptions of the same structures as those of the first embodiment will be omitted or briefly described, and only other structures will be specifically described. In addition, since the schematic structure of the tiling display device is the same as that of FIG. 1 , only the coupling structure in which the actual display panel 210 and the plate 254 of the tiling display device are coupled is specifically illustrated in the drawing.

As shown in FIG. 11 , a first coupling part 260 is formed on each of the rear four corners of the display panel 210 , and a second coupling part 280 is formed on the front surface of the plate 254 of the tiling display device. .

The first coupler 260 and the second coupler 280 are coupled to each other to not only tile the display panel 210 to the plate 254 of the tiling display device, but also to tile the tiled display panel 210 to the plate 254 . ) is aligned with

Referring to FIG. 11 , the fastening part 268 penetrates the outer wall of the main body 262 , but is not limited thereto. For example, the fastening part 268 may have a concave shape formed only on the inner surface of the body 262 .

In the drawings, although the body 262 is configured in a cylindrical cylindrical shape, it is not limited to this shape, and various shapes such as a polygonal cylindrical shape such as a cuboid are possible.

In addition, the second coupling portion 280 is arranged parallel to each other between a pair of fastening bars 282 inserted into the body 262 of the first coupling portion 260 and the pair of fastening bars 282 . A spring 284 that is disposed on and maintains an interval between the fastening bars 282, a fastening protrusion 286 disposed on each of the pair of fastening bars 282, and a tip of each of the pair of fastening bars 282.

Details on this will be described later.

When the display panel 210 is tiled, the fastening bar 282 of the second coupling part 280 is inserted into the moving bar 264 . At this time, the moving bar 264 may be formed in a cylindrical shape like the main body 262 , or may be configured in two parallel bars having the same shape as the fastening bar 282 .

The fastening protrusion 286 of the second coupling part 280 is inserted and fastened to the fastening part 268 of the first coupling part 260 . At this time, the fastening protrusion 286 is composed of an inclined protrusion such as a triangular shape and can be hooked to the fastening part 268 .

At this time, the front end 269 is inclined at a predetermined angle and the fastening protrusion 286 is also formed in a triangular shape with an inclined cross section. Accordingly, the fastening protrusion 286 and the inclined area of the front end 269 come into contact with each other, and as the display panel 210 advances toward the plate 254 , the fastening protrusion 286 touches the inclined area of the front end 269 . By moving along, the distance between the pair of fastening bars 282 is narrowed, and the fastening protrusion 286 enters the inner surface of the body 262 . Here, when the distance between the pair of fastening bars 282 is narrowed, all of the respective fastening bars 282 may move, or only one of the pair of fastening bars 282 is fixed to the plate 254 and the other fastening bar 282 is fastened. It may be configured to move only the bar.

As the tiling magnet 266 moves, the moving bar 264 also moves, and the moving bar 264 moves while in contact with the inclined tip 288 of the pair of fastening bars 282 . Therefore, as the moving bar 264 moves, the distance between the pair of fastening bars 282 becomes narrower, and the fastening state between the fastening protrusion 286 and the fastening groove 269 is released, so the plate 254 of the tiling device.

As shown in FIG. 14B , in a state in which the display panel 310 tiled by the first magnet 135 is attached to the tiling device 120 , the second operation member 127 is operated to obtain a second magnet ( When 137) is brought closer to the front of the display panel 310, the regions facing each other of the second magnet 137 and the second coupling magnet 384 have the same polarity, so the second coupling magnet ( 384 ) is separated from the display panel 310 , and the second coupling magnet 384 and the moving member 385 move toward the plate 354 .

Since the adhesive force between the first magnet 135 and the display panel 310 of the tiling device 120 is greater than that between the attachment member 364 and the first coupling magnet 381 , the display panel 310 is formed by the tiling device. It is separated from this plate 354 .

As described above, in the tiling display device of this embodiment, the display panel 310 is tiled by the magnetic force of the magnets 135 and 137 of the tiling device and the magnets 381 and 384 of the second coupling unit 380 disposed on the plate 354 . and separate Therefore, without mechanical manipulation such as assembly of screws for tiling, the operator simply attaches and detaches the display panel 310 fixed to the tiling device to and from the plate 354 from the front of the tiling display device automatically, so that a small number of Tiling and separation of the display panel 354 can be quickly and easily performed by an operator.
