Description

Technical Field

[0001] The present disclosure relates to a display device, and more particularly, to a display device having improved flatness. Background Art

[0002] Display devices for monitors of computers, televisions (TVs), or cellular phones include self-emitting organic light-emitting displays (OLEDs), liquid crystal displays (LCDs) that require a separate light source, and the like.

[0003] Display devices are widely used in monitors of computers, TVs, and personal portable devices. Also, display devices having a large display area and reduced volume and weight are being studied.

[0004] Recently, tiled display devices that connect multiple display devices to increase the display area are attached to walls and the like to be used as billboards and the like. Summary of the Invention

[0005] First, display devices are used from small electronic devices for mobile phones to large electronic devices such as large TVs. Thus, display devices of small sizes to large sizes of several tens of inches are manufactured for various purposes. However, it is technically difficult to manufacture large-sized display devices of several hundred inches or larger. Therefore, as an alternative, tiled display devices that connect multiple display devices to increase the display area are used. In addition, tiled display devices configured with multiple display devices are attached to the surface of a wall to be used as billboards, large electronic boards in stadiums, outdoor advertising signs, and the like.

[0006] Such a tiled display device can be realized, for example, by fastening a display device to a wall portion. Each display device includes a display panel that is substantially frameless and a frame attached to the rear surface of the display panel to protect the display panel. However, if the frame has low flatness, the flatness of the display panel attached to the frame also decreases. Therefore, a step difference may occur between multiple display devices fastened to the wall portion, and the boundary between the display devices may be visually recognized.

[0007] Therefore, an elastic foam tape is used to attach the frame and the display panel to compensate for the flatness of the display panel caused by the low flatness of the frame. The elastic foam tape can compensate for a decrease in flatness caused by foreign matter between the display panel and the frame or deformation of the frame. Here, only flatness variations smaller than the thickness of the foam tape are considered as defects to be compensated.

[0008] The foam tape has a plurality of holes and has a smaller adhesive force than other adhesive members. Therefore, the foam tape requires a larger adhesive area than other adhesive members. Accordingly, the foam tape is disposed on the entire surface of the frame to attach the display panel and the frame to each other. However, when disassembling the display panel and the frame for repairing or replacing the display panel and / or the frame, there is a problem that it is difficult to remove the foam tape disposed on the entire surface of the frame. In addition, when the display panel is disassembled from the frame, the display panel and the frame may be damaged. Thus, if the display panel and the frame are attached with the foam tape and the flatness is compensated, there is a problem that it is difficult to disassemble the display panel and the frame when repair and replacement of the display panel and the frame are required.

[0009] Accordingly, the present inventors have invented a display device in which the flatness of the display panel can be adjusted regardless of the flatness of the frame, and the display and the frame can be easily reassembled.

[0010] Accordingly, embodiments of the present disclosure relate to a display device that substantially eliminates one or more problems caused by limitations and disadvantages of the prior art.

[0011] An object to be achieved by the present disclosure is to provide a display device having improved flatness.

[0012] Another object to be achieved by the present disclosure is to provide a display device in which the flatness of the display panel is improved regardless of the flatness of the frame.

[0013] Another object to be achieved by the present disclosure is to provide a display device in which the display panel and the frame can be easily attached to and detached from each other.

[0014] Yet another object to be achieved by the present disclosure is to provide a display device having improved attachment reliability between the display panel and the frame.

[0015] Another object to be achieved by the present disclosure is to reduce the movement of the display panel in the space formed between the display panel and the frame when the frame has low flatness.

[0016] The objects of the present disclosure are not limited to the above objects, and other objects not mentioned above will be clearly understood by those skilled in the art from the following description.

[0017] To achieve these and other aspects of the inventive concept, as specifically presented and broadly described, a display device includes a display panel and a frame disposed on a rear surface of the display panel. The display device further includes a plurality of coupling members fixed to the rear surface of the display panel and disposed between the display panel and the frame, and a plurality of coupling members passing through the frame and coupled to the plurality of coupling members in parallel. Accordingly, the flatness of the display panel attached to the plurality of coupling members can be improved by adjusting the positions of the frame and the plurality of coupling members. In addition, the display panel and the frame can be easily attached and detached using the plurality of coupling members and the plurality of coupling members.

[0018] In another aspect, a display device includes a display panel and a plurality of coupling members bonded to a rear surface of the display panel. The display device further includes an adhesive member that bonds the plurality of coupling members and the display panel. In addition, the display panel includes a frame disposed to cover the display panel and the plurality of coupling members, and a plurality of coupling members coupled to the frame and the plurality of coupling members. Some of the plurality of coupling members may be coupled to one surface of the plurality of coupling members, while other coupling members of the plurality of coupling members may be coupled to side surfaces of the plurality of coupling members. Accordingly, the flatness of the display panel can be improved by adjusting the coupling positions between the frame and the plurality of coupling members in consideration of the flatness of the frame.

[0019] Other details of the exemplary embodiments are included in the detailed description and the drawings.

[0020] According to the present disclosure, the flatness of the display panel can be easily adjusted without being limited to the flatness of the frame.

[0021] According to the present disclosure, the frame and the display panel can be easily reassembled.

[0022] According to the present disclosure, the bonding quality between the display panel and the frame can be improved.

[0023] According to the present disclosure, the movement of the display panel in the space between the display panel and the frame can be reduced.

[0024] It will be understood that the foregoing general description and the following detailed description are both exemplary and explanatory and are intended to provide further explanation of the claimed inventive concept. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] By referring to the following detailed exemplary embodiments in conjunction with the appended Figure 1 drawings, the advantages and features of the present disclosure and the methods for achieving these advantages and features will become clear. However, the present disclosure is not limited to the exemplary embodiments disclosed herein, but will be implemented in various forms. The exemplary embodiments are provided only by way of example so that those skilled in the art can fully understand the disclosure content of the present disclosure and the scope of the present disclosure. Therefore, the present disclosure will be defined only by the scope of the appended claims.

[0037] The shapes, sizes, ratios, angles, quantities, etc. shown in the drawings for describing the exemplary embodiments of the present disclosure are merely examples, and the present disclosure is not limited thereto. Throughout the specification, the same reference numerals generally denote the same elements. In addition, in the following description of the present disclosure, detailed descriptions of known related technologies may be omitted to avoid unnecessarily obscuring the subject matter of the present disclosure. Terms such as "comprising", "having", and "including" used herein generally intend to allow the addition of other components, unless these terms are used together with the term "only". Any reference to the singular may include the plural unless otherwise expressly stated.

[0038] Components are interpreted to include a normal error range even if not expressly stated.

[0039] When using terms such as "on", "above", "under", and "next to" to describe the positional relationship between two components, one or more components may be located between the two components, unless the term is used together with the terms "immediately" or "directly".

[0040] When an element or layer is disposed "on" another element or layer, another layer or another element may be directly disposed on the other element or between them.

[0041] Although terms such as "first", "second", etc. are used to describe various components, these components are not limited by these terms. These terms are only used to distinguish one component from other components. Therefore, the first component mentioned below may be the second component in the technical concept of the present disclosure.

[0042] Throughout the specification, the same reference numerals generally denote the same elements.

[0043] For ease of description, the dimensions and thicknesses of each component shown in the drawings are shown, and the present disclosure is not limited to the dimensions and thicknesses of the components shown.

[0044] The features of the various embodiments of the present disclosure may be partially or wholly adhered to or combined with each other, and may be interlocked and operated in various technical ways, and the embodiments may be executed independently or in association with each other.

[0045] Hereinafter, a tiled display device according to an exemplary embodiment of the present disclosure will be described in detail with reference to the drawings.

[0046] Figure 1 is a perspective view of a tiled display device according to an exemplary embodiment of the present disclosure. Referring to Figure 1 , a tiled display device 1000 according to an exemplary embodiment of the present disclosure is formed by connecting a plurality of display devices 100 according to an exemplary embodiment of the present disclosure.

[0047] Referring toFigure 1 According to an exemplary embodiment of the present disclosure, the tiled display device 1000 includes a plurality of display devices 100 and a wall portion 200. Since the tiled display device 1000 is composed of a plurality of display devices 100, the display area of the displayed image can be increased.

[0048] Each of the plurality of display devices 100 is attached to the wall portion 200 so as to be set as if it were a single display device. For example, the plurality of display devices 100 may be attached to the wall portion 200 in a tiled form to implement the tiled display device 1000.

[0049] Since the tiled display device 1000 has a very large size, it is difficult to move the plurality of display devices 100 in a connected state to the installation position. Therefore, the plurality of display devices 100 may be moved to the installation position and then assembled into the tiled display device 1000 at the installation position.

[0050] The plurality of display devices 100 may be attached as close as possible so that the intervals between the plurality of display devices 100 are constant and reduced. Therefore, the plurality of display devices 100 look like a single display device 100. That is, the plurality of display devices 100 are precisely aligned to be attached to the wall portion 200 so that the boundaries that do not display images can be reduced.

[0051] In this case, the plurality of display devices 100 may be aligned in the X-axis direction, Y-axis direction, and Z-axis direction to be attached to the wall portion 200. When the plurality of display devices 100 are aligned in the X-axis direction, the left and right edges of the plurality of display devices 100 respectively arranged in the same column may be linearly aligned. In addition, when the plurality of display devices 100 are aligned in the Y-axis direction, the upper and lower edges of the plurality of display devices 100 respectively arranged in the same row may be linearly aligned. In addition, when the plurality of display devices 100 are aligned in the Z-axis direction, all the front surfaces of the plurality of display devices 100 may be aligned on a flat surface to remove the step difference between the plurality of display devices 100.

[0052] If the plurality of display devices 100 are not aligned in any one of the X-axis, Y-axis, and Z-axis directions, the boundaries that do not display images between the plurality of display devices 100 may be visually recognized by the user. When the boundaries are visually recognized by the user, the immersion feeling when the user views the image may be suppressed, and it may be difficult to display a clear image.

[0053] Therefore, when multiple display devices 100 are attached to the wall portion 200, it is important to align the multiple display devices 100 in each of the X-axis direction, Y-axis direction, and Z-axis direction. Further, when the multiple display devices 100 are attached to the wall portion 200 using fastening members, the attachment positions of the multiple display devices 100 can be mainly aligned. However, due to errors generated when an operator attaches the multiple display devices 100 or mechanical tolerances, slight misalignment between the multiple display devices 100 may occur. For example, if the positions of the multiple display devices 100 in the Z-axis direction (i.e., the respective flatness of the multiple display devices 100) are different from each other, the boundary between the multiple display devices 100 may be visually recognized. Therefore, it may be important to improve the respective flatness of the multiple display devices 100. Accordingly, in the tiled display device 1000 according to an exemplary embodiment of the present disclosure, a plurality of first coupling members BD1 are provided in each display device 100 to improve the respective flatness of the multiple display devices 100. Accordingly, the alignment error in the Z-axis direction can be reduced.

[0054] Hereinafter, reference will be made to Figures 2 to 4 describe in detail the display device 100 according to an exemplary embodiment of the present disclosure.

[0055] Figure 2 is an exploded perspective view of a display device according to an exemplary embodiment of the present disclosure. Figure 3 is an exploded perspective view of a display device according to an exemplary embodiment of the present disclosure. Figure 4 is a rear view of a display device according to an exemplary embodiment of the present disclosure. Specifically, Figure 2 is an exploded perspective view of the display device 100 as viewed from the rear surface of the display device 100. Figure 3 is an exploded perspective view of the display device 100 as viewed from the front surface of the display device 100. For ease of description, Figure 3 illustrates the frame 150, a plurality of first coupling members BD1, a plurality of first coupling members SC1, a plurality of adhesive members AD, a plurality of panel magnets MG, and a plurality of panel ferromagnetic materials MS. Figure 4 the illustration of the shield 160 is omitted.

[0056] Reference is made to Figure 2 , the display device 100 includes a protection plate 110, a display panel 120, a plurality of flexible films 130, a printed circuit board 140, a frame 150, a shield 160, and a cooling fan 170. Further, the display device 100 includes a plurality of panel magnets MG, a plurality of panel ferromagnetic materials MS, a plurality of first coupling members BD1, and a plurality of adhesive members AD.

[0057] First, the display panel 120 is configured to display an image to a user. In the display panel 120, display elements and circuits, wirings, components, etc. for driving the display elements may be arranged. The display elements may be defined in different ways according to the type of the display panel 120. For example, when the display panel 120 is an organic light-emitting display panel, the display element may be an organic light-emitting diode including an anode, an organic light-emitting layer, and a cathode. For example, when the display panel 120 is an inorganic light-emitting display panel, the display element may be a light-emitting diode (LED) or a micro-LED including an N-type semiconductor layer, a p-type semiconductor layer, and a light-emitting layer. However, the display panel 120 is not limited thereto, and the display elements of the display panel 120 may be configured in various forms.

[0058] A plurality of flexible films 130 are adhered to the rear surface of the display panel 120. The flexible film 130 may be a film on which various components are provided on a ductile base film. The flexible film 130 may supply signals to the display elements and the circuits and may be electrically connected to the display panel 120. The plurality of flexible films 130 may supply a power supply voltage, a data voltage, etc. to the display panel 120. Figure 2 Six flexible films 130 adhered to the long side of the display panel 120 are shown. However, the number and positions of the plurality of flexible films 130 may vary according to design and are not limited thereto.

[0059] On the plurality of flexible films 130, driver ICs such as a gate driver IC or a data driver IC may be provided. The driver IC is configured to process data for displaying an image and driving signals for processing the data. According to the mounting method, the driver IC may be mounted by a chip on glass (COG) method, a chip on film (COF) method, a tape carrier package (TCP) method, etc. However, for ease of description, the driver IC is described as being mounted on the plurality of flexible films 130 by the COF method, but the present disclosure is not limited thereto.

[0060] The printed circuit board 140 is electrically connected to the plurality of flexible films 130. The printed circuit board 140 is configured to supply signals to the driver IC. On the printed circuit board 140, various components for supplying various signals such as driving signals or data signals to the driver IC may be provided. Figure 2 A single printed circuit board 140 is shown. However, the number of the printed circuit boards 140 may vary according to design and is not limited thereto.

[0061] The frame 150 is disposed on the rear surface of the display panel 120. The frame 150 on the rear surface of the display panel 120 can support and protect the display panel 120. The frame 150 can be made of a rigid material. For example, the frame 150 can be made of a metal material such as aluminum (Al), copper (Cu), zinc (Zn), silver (Ag), gold (Au), iron (Fe), stainless steel (SUS), or invar, a plastic material, etc.

[0062] The frame 150 can have a shape corresponding to the edge of the display panel 120. For example, the frame 150 can have a frame shape corresponding to the edge of the display panel 120. The frame 150 can support the edge of the display panel 120 to maintain the flatness of the display panel 120. Alternatively, the frame 150 can have the same shape as the planar shape of the display panel 120, and the shape of the frame 150 is not limited thereto as long as it can support the display panel 120.

[0063] Referring to Figure 2 and Figure 3 , the frame 150 includes a plurality of grooves 151 and a plurality of holes 153.

[0064] A plurality of first coupling members BD1 are respectively mounted on the plurality of grooves 151. The plurality of grooves 151 can be formed in one surface of the frame 150 facing the display panel 120, and the plurality of first coupling members BD1 can be inserted into the plurality of grooves 151. The plurality of grooves 151 are provided in the frame 150 having a shape corresponding to the edge of the display panel 120, so that they can overlap with the display panel 120 near the edge. In the drawing, three grooves 151 are illustrated as being respectively provided at each of the upper and lower ends of the frame 150, but the number and position of the plurality of grooves 151 are not limited thereto.

[0065] A plurality of panel magnets MG and a plurality of panel ferromagnetic materials MS are inserted into the plurality of holes 153. The plurality of holes 153 are formed by passing through one surface of the frame 150 facing the display panel 120 and the surface opposite thereto. The plurality of panel magnets MG and the plurality of panel ferromagnetic materials MS can be inserted into the plurality of holes 153. The plurality of holes 153 are provided in the frame 150 having a shape corresponding to the edge of the display panel 120, so that they can overlap with the display panel 120 near the edge. In the drawing, two holes 153 are illustrated as being respectively provided at each of the left and right sides of the frame 150, but the number and position of the plurality of holes 153 are not limited thereto.

[0066] In addition, the frame 150 further includes a plurality of first coupling holes formed in the bottom surfaces of the plurality of grooves 151 to allow a plurality of first coupling members SC1 to pass through. This will be described in detail with reference to Figure 5A and Figure 5B in detail.

[0067] Reference Figure 2 and Figure 3 , a plurality of first coupling members BD1 are disposed between the display panel 120 and the frame 150. The plurality of first coupling members BD1 are configured to couple the display panel 120 and the frame 150. In addition, the plurality of first coupling members BD1 are configured to adjust the flatness of the display panel 120.

[0068] The plurality of first coupling members BD1 may be disposed along the edge of the display panel 120. The long sides of the plurality of first coupling members BD1 may be disposed along the edge of the display panel 120. The long sides of the plurality of first coupling members BD1 may be parallel to the nearest edge of the display panel 120. For example, the long side of the first coupling member BD1 disposed adjacent to the upper edge of the display panel 120 may be parallel to the upper edge of the display panel 120. If the long sides of the plurality of first coupling members BD1 are disposed along the edge of the display panel 120, the flatness of the display panel 120 can be adjusted more easily. Reference will be made to Figure 5A and Figure 5B for a more detailed description of the adjustment of the flatness of the display panel 120 by the plurality of first coupling members BD1.

[0069] In the drawings, three first coupling members BD1 are illustrated as being disposed adjacent to the upper edge of the display panel 120, and three first coupling members BD1 are illustrated as being disposed adjacent to the lower edge of the display panel 120. However, the plurality of first coupling members BD1 may be disposed at the left and right edges of the display panel 120, and the number and position of the plurality of first coupling members BD1 are not limited thereto.

[0070] The plurality of first coupling members BD1 include first fixing holes BDH1 to be coupled to the plurality of first coupling members SC1. The plurality of first coupling members BD1 may be inserted into the plurality of grooves 151 of the frame 150 to be coupled to the plurality of first coupling members SC1. The plurality of first coupling members BD1 may be mounted within the plurality of grooves 151 to be coupled to the plurality of first coupling members SC1. The first fixing holes BDH1 are configured to be coupled to the plurality of first coupling members SC1 and may be formed in a surface of the first coupling member BD1 facing the bottom surface of the plurality of grooves 151. The first fixing holes BDH1 may be provided corresponding to the plurality of first coupling holes of the frame 150.

[0071] The plurality of first coupling members SC1 passing through the plurality of first coupling holes may be disposed on the rear surface of the frame 150. The plurality of first coupling members SC1 may be coupled to the plurality of first coupling members BD1, and the frame 150 is inserted between the first coupling member SC1 and the first coupling member BD1. Here, the plurality of first coupling members SC1 may be inserted into the first fixing holes BDH1 of the plurality of first coupling members BD1 to be coupled to the plurality of first coupling members BD1.

[0072] For example, the plurality of first coupling members SC1 may be threaded screws. In addition, the first fixing holes BDH1 of the plurality of first engaging members BD1 into which the plurality of first coupling members SC1 are inserted may be holes having threads on the inner circumferential surface. In this case, the heads of the first coupling members SC1 are disposed on the rear surface of the frame 150, and at least a portion of the threads may be inserted into the first fixing holes BDH1 within the plurality of grooves 151. Although the plurality of first coupling members SC1 are shown as screws in the drawings, the type of the plurality of first coupling members SC1 is not limited thereto. Hereinafter, for ease of description, it will be assumed that the plurality of first coupling members SC1 are threaded screws and the first fixing holes BDH1 of the first engaging members BD1 are holes having threads on the inner circumferential surface. However, the present disclosure is not limited thereto.

[0073] If the threaded first coupling member SC1 is inserted into the first fixing hole BDH1 and rotated in either the clockwise or counterclockwise direction, the first coupling member SC1 can rotate in place. In addition, the first engaging member BD1 can move in a direction away from the first coupling member SC1 along the threads of the first coupling member SC1. That is, if the first coupling member SC1 rotates in one direction, the first engaging member BD1 moves along the threads of the first coupling member SC1. Therefore, the first engaging member BD1 can move to the outside of the plurality of grooves 151 and move toward the display panel 120, and can eventually separate from the first coupling member SC1.

[0074] Conversely, if the first coupling member SC1 rotates in the other of the clockwise and counterclockwise directions, the first coupling member SC1 can rotate in place. In addition, the first engaging member BD1 can move in a direction of being coupled to the first coupling member SC1 along the threads of the first coupling member SC1. That is, if the first coupling member SC1 rotates in the other direction, the first engaging member BD1 moves along the threads of the first coupling member SC1. Therefore, the first engaging member BD1 can move to the inside of the plurality of grooves 151 and move toward the frame 150, and can eventually be coupled to the threads of the first coupling member SC1 as much as possible. Therefore, the first coupling member SC1 is rotated in the clockwise or counterclockwise direction to adjust the outer surfaces of the plurality of first engaging members BD1 to be disposed in the same plane.

[0075] A plurality of adhesive members AD are disposed between the plurality of first engaging members BD1 and the display panel 120. The adhesive members AD may be made of an adhesive material to fix the first engaging members BD1 to the rear surface of the display panel 120. For example, the adhesive members AD may be a sticky acrylic double-sided tape, but are not limited thereto.

[0076] A plurality of panel magnets MG are disposed on the rear surface of the display panel 120. The plurality of panel magnets MG on the rear surface of the display panel 120 can be inserted into the plurality of holes 153 of the frame 150. The plurality of panel magnets MG are disposed on the rear surface of the display panel 120 and are used to attach the display device 100 to the wall portion 200. For example, each of the plurality of panel magnets MG can be a bar magnet having one N pole and one S pole, but is not limited thereto. Here, the plurality of panel magnets MG can be fixed to the plurality of holes 153 of the frame 150 using an adhesive member AD or other fastening members, but is not limited thereto.

[0077] A plurality of panel ferromagnetic materials MS are disposed on the rear surface of the display panel 120. The plurality of panel ferromagnetic materials MS on the rear surface of the display panel 120 can be disposed in the plurality of holes 153 of the frame 150. The plurality of panel ferromagnetic materials MS can be disposed on two side surfaces of each of the plurality of panel magnets MG. Each of the plurality of panel magnets MG can be disposed between the plurality of panel ferromagnetic materials MS. For example, one of the plurality of panel ferromagnetic materials MS can be in contact with the N pole of the panel magnet MG, and the other panel ferromagnetic material MS can be in contact with the S pole of the panel magnet MG. Each of the plurality of panel magnets MG can be disposed between two panel ferromagnetic materials MS. The plurality of panel ferromagnetic materials MS can be made of a ferromagnetic material such as steel, but is not limited thereto.

[0078] The display device 100 can be attached to the wall portion 200 using the plurality of panel magnets MG and the plurality of panel ferromagnetic materials MS. For example, when the display device 100 is brought into contact with the wall portion 200, magnetic lines of force are induced between the wall portion 200, the panel magnet MG, and the panel ferromagnetic material MS. Therefore, the display device 100 can be fixed to the wall portion 200. Here, the display device 100 can also be attached to the wall portion 200 using only the plurality of panel magnets MG without using the plurality of panel ferromagnetic materials MS. The method of attaching the display device 100 to the wall portion 200 using the plurality of panel magnets MG and the plurality of panel ferromagnetic materials MS is merely an example. Instead of the plurality of panel magnets MG and the plurality of panel ferromagnetic materials MS, other fastening members can be provided. However, the present disclosure is not limited thereto.

[0079] Refer to Figure 2 and Figure 4, the shield 160 is disposed on the rear surface of the frame 150. The shield 160 on the rear surface of the frame 150 can cover the plurality of flexible films 130 and the printed circuit board 140. Specifically, the plurality of flexible films 130 are adhered to the rear surface of the display panel 120. In addition, the frame 150 on the rear surface of the display panel 120 can be coupled to the display panel 120 using the first coupling member BD1. Here, the plurality of flexible films 130 and the printed circuit board 140 are not disposed between the display panel 120 and the frame 150, but are disposed to cover the frame 150. Each of the plurality of flexible films 130 is a film in which various components are disposed on the extensible base film as described above and can thus be easily bent. Therefore, the plurality of flexible films 130 are bent to cover the frame 150, so that the plurality of flexible films 130 and the printed circuit board 140 are disposed on the display panel 120 and the frame 150.

[0080] The shield 160 is arranged to cover the display panel 120, the plurality of flexible films 130, the printed circuit board 140 and the frame 150. Specifically, the frame 150 does not cover the plurality of flexible films 130 and the printed circuit board 140. Therefore, it may be difficult to protect the plurality of flexible films 130 and the printed circuit board 140 from external impacts. Therefore, the shield 160 can be disposed on the rear surface of the frame 150 to protect the plurality of flexible films 130 and the printed circuit board 140. The shield 160 is arranged to cover the display panel 120, the plurality of flexible films 130, the printed circuit board 140 and the frame 150. Therefore, the shield 160 can protect other components of the display device 100, especially the plurality of flexible films 130 and the printed circuit board 140.

[0081] The shield 160 includes a plurality of first holes 161 that expose the plurality of panel magnets MG and the plurality of panel ferromagnetic materials MS, and a plurality of second holes 162 for heat dissipation.

[0082] Referring to Figure 2 , the plurality of first holes 161 expose the plurality of panel magnets MG and the plurality of panel ferromagnetic materials MS fixed to the rear surface of the frame 150. The plurality of panel magnets MG and the plurality of panel ferromagnetic materials MS exposed through the plurality of first holes 161 can be brought into closer contact with the wall portion 200, and the intensity of the magnetic field lines can be increased. If the plurality of panel magnets MG and the plurality of panel ferromagnetic materials MS are covered by the shield 160, the shield 160 may increase the distance between the wall portion 200 and the plurality of panel magnets MG and the plurality of panel ferromagnetic materials MS. Therefore, the intensity of the magnetic field lines may decrease, and the display device 100 may be separated from the wall portion 200. Therefore, the plurality of first holes 161 can be arranged such that the plurality of panel magnets MG and the plurality of panel ferromagnetic materials MS are disposed adjacent to the wall portion 200. Therefore, the display device 100 can be firmly attached to the wall portion 200.

[0083] A plurality of second holes 162 may be arranged to overlap at least the flexible film 130 and the printed circuit board 140. The plurality of second holes 162 are configured to dissipate heat generated from the display device 100 when the display device 100 is driven. Here, the plurality of second holes 162 are arranged to overlap at least the flexible film 130 and the printed circuit board 140 having high heat generation characteristics. Accordingly, heat generated from the display device 100 can be effectively dissipated. Figure 2 It is shown that the plurality of second holes 162 are provided at the upper side of the shield 160, the lower side of the shield 160, and the central portion of the shield 160. However, the positions of the plurality of second holes 162 are not limited thereto.

[0084] A heat dissipation fan 170 may be provided on the rear surface of the display panel 120. The heat dissipation fan 170 may circulate air between the shield 160 and the display panel 120 to dissipate heat generated when the display device 100 is driven. The heat dissipation fan 170 may be used to convect air inside the display device 100, thereby dissipating heat from the display device 100. Here, air may be introduced and discharged through the heat dissipation fan 170 and the plurality of second holes 162 of the shield 160. Figure 2 Four heat dissipation fans 170 are shown. However, the heat dissipation fan 170 may be omitted according to the design, and the number and position of the heat dissipation fan 170 are not limited thereto.

[0085] A protection plate 110 is provided to cover the front surface of the display panel 120. The protection plate 110 may be provided to cover the display panel 120 to protect the display panel 120 from external impacts, moisture, heat, etc. The protection plate 110 may be made of a material having impact resistance and light transmissivity. For example, the protection plate 110 may be a substrate made of glass. In addition, the protection plate 110 may be a film made of a plastic material such as polycarbonate (PC), polyimide (PI), polymethyl methacrylate (PMMA), and polyethylene terephthalate (PET), but is not limited thereto.

[0086] As described above, the display panel 120 can be coupled to the frame 150 using a plurality of first coupling members BD1 and a plurality of first coupling members SC1. The frame 150 can be made of a rigid material such as metal to support the display panel 120. If the frame 150 is made of a metal material, the frame 150 can be manufactured by extrusion or the like. However, due to various tolerances in the manufacture of the frame 150, the flatness of the frame 150 may be different from the design value. For example, the plurality of corners of the frame 150 are located at different positions in the Z-axis direction, and thus may be disposed on different XY planes. When the frame 150 has low flatness, the flatness of the display panel 120 fixed to the frame 150 may vary due to the influence of the flatness of the frame 150. For example, if the display panel 120 is fixed to the frame 150 in which one of its plurality of corners is disposed on a different XY plane from another corner, one of the corners of the display panel 120 may also be disposed on a different XY plane from another corner. Therefore, the edges of the display panel 120 may not be disposed on the same plane, and the flatness of the display panel 120 may be reduced.

[0087] Then, if the tiled display device 1000 is achieved by aligning the display device 100 on the wall portion 200, a step difference may be generated in the Z-axis direction between the plurality of display devices 100. Therefore, the boundary between the plurality of display devices 100 may be visually recognized. That is, a step difference may be generated between the edges of the display device 100, and thus the boundary may be visually recognized. In the display device 100 according to an exemplary embodiment of the present disclosure, regardless of the flatness of the frame 150, the flatness of the display panel 120 can be improved using a plurality of first coupling members BD1 and a plurality of first coupling members SC1.

[0088] Hereinafter, reference will be made to Figure 5A and Figure 5B to describe the adjustment of the flatness of the display panel 120, that is, the Z-axis step difference, using a plurality of first coupling members BD1 and the first coupling member SC1.

[0089] Figure 5A and Figure 5B are cross-sectional views taken along the line V-V' of Figure 4 . Specifically, Figure 5A shows a cross-sectional view of the display device 100 according to an exemplary embodiment of the present disclosure and an enlarged view of the first coupling member SC1' among the plurality of first coupling members SC1. Figure 5B shows a cross-sectional view of the display device 100 according to an exemplary embodiment of the present disclosure and an enlarged view of another first coupling member SC1" among the plurality of first coupling members SC1. For ease of description, Figure 5A and Figure 5B the illustration of the cross-sections of the plurality of flexible films 130 and the printed circuit board 140 is omitted.

[0090] Hereinafter, for ease of description, one of the plurality of first coupling members SC1 in the region where the gap between the display panel 120 and the frame 150 is the largest is defined as the first coupling member SC1'. In addition, one of the plurality of first coupling members SC1 in the region where the gap between the display panel 120 and the frame 150 is the smallest is defined as the first coupling member SC1". However, this is only an example, and the present disclosure is not limited thereto.

[0091] Referring to Figure 5A and Figure 5B , the frame 150 includes a plurality of first coupling holes 152. The plurality of first coupling holes 152 are formed in the bottom surfaces of the plurality of grooves 151 and may communicate with the plurality of grooves 151. The plurality of first coupling members SC1 may pass through the plurality of first coupling holes 152. The plurality of first coupling members SC1 may be inserted into the first fixing holes BDH1 of the first coupling member BD1 through the plurality of first coupling holes 152, where the first coupling member BD1 is inserted into the plurality of grooves 151.

[0092] Here, the plurality of first coupling holes 152 may have a smaller size than the heads of the plurality of first coupling members SC1 to allow only the threads of the plurality of first coupling members SC1 to pass through them. If the plurality of first coupling holes 152 have a larger size than the heads of the plurality of first coupling members SC1, the heads of the plurality of first coupling members SC1 cannot be fixed to the rear surface of the frame 150. Moreover, the first coupling member BD1 and the plurality of first coupling members SC1 may be separated from the frame 150. Therefore, the plurality of first coupling holes 152 may have a smaller size than the heads of the plurality of first coupling members SC1 to fix the frame 150 and the display panel 120.

[0093] The plurality of first coupling members SC1 may be inserted into the first fixing holes BDH1 of the first coupling member BD1 to different depths respectively. For example, a part of the frame 150 provided with the first coupling member SC1' among the plurality of first coupling members SC1 may be provided on a different plane from another part of the frame 150 provided with the first coupling member SC1". That is, if the frame 150 has low flatness, one surface of the frame 150 may not be provided on the same plane. For example, the gap X1 between a part of the frame 150 provided with the first coupling member SC1' and the display panel 120 may be the largest. In addition, the gap X2 between another part of the frame 150 provided with the first coupling member SC1" and the display panel 120 may be the smallest. If the frame 150 and the display panel 120 are attached to each other without using the first coupling member BD1 and the first coupling members SC1, the edge of the display panel 120 may be deformed to correspond to the edge of the frame 150. Therefore, the flatness may be reduced.

[0094] Reference Figure 5A , the gap Y1 between the first coupling member SC1' among the plurality of first coupling members SC1 and the display panel 120 can be maximized. In other words, the first coupling member SC1' can be the first coupling member SC1 in the portion where the gap X1 between the frame 150 and the display panel 120 is the largest. Specifically, the head of each of the plurality of first coupling members SC1 contacts the rear surface of the frame 150. Therefore, the gap between the plurality of first coupling members SC1 and the display panel 120 may be affected by the flatness of the frame 150. Accordingly, in the region where the gap X1 between the frame 150 and the display panel 120 is the largest, the gap Y1 between the first coupling member SC1' and the display panel 120 can be maximized. In this case, the first coupling member SC1' can be inserted into the first fixing hole BDH1 to the minimum depth, and the first engaging member BD1 coupled to the first coupling member SC1' can protrude outside the plurality of grooves 151.

[0095] In the region where the gap X1 between the frame 150 and the display panel 120 is the largest, a part of the first coupling member SC1' inserted into the first engaging member BD1 can have the minimum length. As the length of the part of the first coupling member SC1' inserted into the first engaging member BD1 increases, the first engaging member BD1 can be set closer to the bottom surface of the plurality of grooves 151. On the contrary, when the length of the part of the first coupling member SC1' inserted into the first engaging member BD1 decreases, the first engaging member BD1 can become farther from the bottom surface of the plurality of grooves 151. In addition, the first engaging member BD1 can protrude outside the plurality of grooves 151. In the region where the gap X1 between the frame 150 and the display panel 120 is the largest, the part of the first coupling member SC1' inserted into the first engaging member BD1 can be designed to have the minimum length. Accordingly, the first engaging member BD1 can protrude outside the groove 151, and the outer side surface of the first engaging member BD1 can be set on the same plane as the outer side surfaces of the other first engaging members BD1. Therefore, even if the frame 150 has low flatness, the flatness of the display panel 120 fixed to the first engaging member BD1 can be compensated by adjusting the length of the part of the first coupling member SC1 inserted into the first engaging member BD1.

[0096] Reference Figure 5B, the interval Y2 between the first coupling member SC1" among the plurality of first coupling members SC1 and the display panel 120 can be minimized. In other words, the first coupling member SC1" can be the first coupling member SC1 in the portion where the interval X2 between the frame 150 and the display panel 120 is minimized. As described above, the head of each of the plurality of first coupling members SC1 is disposed on the rear surface of the frame 150. Therefore, the interval Y2 between each of the plurality of first coupling members SC1 and the display panel 120 may be affected by the flatness of the frame 150. Thus, in the region where the interval X2 between the frame 150 and the display panel 120 is minimized, the interval Y2 between the first coupling member SC1" and the display panel 120 can be minimized. In this case, the first coupling member SC1" can be inserted into the first fixing hole BDH1 to the maximum depth. In addition, compared with other first engaging members BD1, the first engaging member BD1 coupled to the first coupling member SC1" can be disposed closest to the bottom surface of the plurality of grooves 151.

[0097] In the region where the interval X2 between the frame 150 and the display panel 120 is minimized, the portion of the first coupling member SC1" inserted into the first engaging member BD1 can have the maximum length. In the region where the interval X2 between the frame 150 and the display panel 120 is minimized, the portion of the first coupling member SC1" inserted into the first engaging member BD1 is designed to have the maximum length. Thus, the first engaging member BD1 can be installed within the groove 151, and the outer surface of the first engaging member BD1 can be disposed on the same plane as the outer surfaces of the other first engaging members BD1. Therefore, even if the frame 150 has low flatness, the flatness of the display panel 120 fixed to the first engaging member BD1 can be compensated by adjusting the length of the portion of the first coupling member SC1 inserted into the first engaging member BD1.

[0098] In addition, a plurality of first coupling members BD1 may be disposed along the edge of the display panel 120, that is, the long sides of the plurality of first coupling members BD1 are disposed corresponding to the edge of the display panel 120. Accordingly, the flatness of the display panel 120 can be adjusted more easily. In the tiled display device 1000, if there is a step difference between the edges of adjacent display panels 120, the boundary may be visually recognized. Therefore, it is important to remove the step difference between the edges of the plurality of display panels 120. Accordingly, the plurality of first coupling members BD1 are disposed along the edge of the display panel 120 such that the Z-axis step difference at the edge of the display panel 120 can be easily adjusted. If the plurality of first coupling members BD1 are disposed closer to the central portion of the display panel 120 than to the edge of the display panel 120, it is difficult to adjust the Z-axis step difference at the edge of the display panel 120 even when using the first coupling member BD1. Accordingly, the plurality of first coupling members BD1 are disposed along the edge of the display panel 120, and thus, the adjustment of the flatness of the display panel 120 can be improved using the plurality of first coupling members BD1.

[0099] For example, if a display panel is attached to a frame whose entire surface is coated with an adhesive member, the flatness of the display panel may vary according to the flatness of the frame. Accordingly, a foam tape may be used to attach the display panel to the frame to compensate for the reduction in the flatness of the display panel caused by the flatness of the frame. If the frame is deformed or there is a foreign object between the display panel and the frame, the flatness of the display panel may vary, but the elastic foam tape is deformed instead of the display panel. Accordingly, the change in the flatness of the display panel can be reduced. However, the flatness of the display panel can be compensated within the range of the thickness of the foam tape or less. Therefore, the foam tape is limited in compensating for the flatness of the display panel. In order to compensate for the flatness of the display panel, increasing the flatness of the frame has been considered instead of using the foam tape that can only compensate for deformation within the thickness or less. However, increasing the flatness of the frame results in an increase in manufacturing cost.

[0100] In the display device 100 according to an exemplary embodiment of the present disclosure, a plurality of first coupling members BD1 are provided between the display panel 120 and the frame 150. Accordingly, an increase in manufacturing cost can be minimized and the flatness of the display panel 120 can be easily improved. Specifically, if the frame 150 provided on the rear surface of the display panel 120 to support the edge of the display panel 120 has low flatness, the flatness of the edge of the display panel 120 will also be reduced. In this case, a plurality of first coupling members BD1 are provided between the display panel 120 and the frame 150, and the length of the first coupling member SC1 inserted into the plurality of first coupling members BD1 can be adjusted. Accordingly, the flatness of the display panel 120 can be improved. The plurality of first coupling members SC1 may pass through the first coupling holes 152 of the frame 150 from the rear surface of the frame 150 and then may be inserted into the first coupling members BD1 between the frame 150 and the display panel 120. Then, the plurality of first coupling members SC1 inserted into the first fixing holes BDH1 of the plurality of first coupling members BD1 may be rotated in a clockwise or counterclockwise direction. In this case, the plurality of first coupling members BD1 may move toward the inside or outside of the plurality of grooves 151 along the threads on the inner circumferential surface of the first fixing holes BDH1. Accordingly, by rotating the plurality of first coupling members SC1, the positions of the plurality of first coupling members BD1 can be adjusted in the Z-axis direction. In addition, the position of a part of the display panel 120 adhered to the plurality of first coupling members BD1 can be adjusted in the Z-axis direction. Accordingly, in the display device 100 according to an exemplary embodiment of the present disclosure, a plurality of first coupling members BD1 movable in the Z-axis direction are provided between the display panel 120 and the frame 150. Accordingly, the flatness of the display panel 120 can be easily adjusted regardless of the flatness of the frame 150.

[0101] In addition, in order to attach the display panel to the frame, it may be considered to dispose a foam tape on the entire surface of the frame. However, when it is necessary to separate the display panel from the frame due to defective assembly of the display panel and the frame, it is difficult to remove the adhesive member coated on the entire surface of the frame. Moreover, the display panel and the frame may be damaged during the process of separating the display panel from the frame.

[0102] Therefore, in the display device 100 according to an exemplary embodiment of the present disclosure, the display panel 120 and the frame 150 are assembled by screw coupling. Accordingly, the display panel 120 and the frame 150 can be easily attached to and detached from each other. Specifically, the display panel 120 and the plurality of first coupling members BD1 are adhered to each other using an adhesive member AD. In addition, the plurality of first coupling members SC1 that adhere the display panel 120 can be coupled to the frame 150 using the plurality of first coupling members BD1. The plurality of first coupling members SC1 and the plurality of first coupling members BD1 can be coupled to or detached from each other by screw coupling. Accordingly, the plurality of first coupling members BD1 can be easily detached from the plurality of first coupling members SC1, and the display panel 120 can also be easily detached from the frame 150. Therefore, the display panel 120 and the frame 150 are attached to and detached from each other using the plurality of first coupling members BD1 and the plurality of first coupling members SC1 that are screw-coupled to each other. Accordingly, damage to the display panel 120 and the frame 150 during disassembly and reassembly of the display panel 120 and the frame 150 can be reduced. Moreover, the display panel 120 and the frame 150 can be easily reassembled.

[0103] In addition, since the flatness of the display panel 120 is compensated by using the first coupling member SC1 and the first coupling member BD1, the adhesive member AD is not limited to a foam tape for flatness compensation, and various types of adhesive members AD can be employed. The foam tape can compensate for flatness, but needs to have a larger adhesion area and stronger adhesive force than other adhesive members. In addition, in the display device 100 according to an exemplary embodiment of the present disclosure, the foam tape is not used to adjust flatness. Accordingly, an adhesive member AD having a larger adhesion area and larger adhesive force can be used. For example, the adhesive member AD can be an acrylic double-sided tape and can have an improved adhesion area and adhesive force compared to the foam tape. Accordingly, using the adhesive member AD can improve the adhesion quality of the display panel 120 adhered to the plurality of first coupling members BD1.

[0104] Figure 6 is an exploded perspective view of a display device according to another exemplary embodiment of the present disclosure. Figure 7A and Figure 7B is a cross-sectional view of a display device according to another exemplary embodiment of the present disclosure. Specifically, Figure 6 is a perspective view observed from the front surface of the display device 600. For ease of description, Figure 6 only the frame 150, the plurality of first coupling members BD1, the plurality of first coupling members SC1, the plurality of adhesive members AD, the plurality of panel magnets MG, and the plurality of panel ferromagnetic materials MS are shown. Figure 7A is a cross-sectional view of a first buffer pad PD1 of a display device 600 according to another exemplary embodiment of the present disclosure. Figure 7BFIG. 0 is a cross-sectional view of a second buffer pad PD2 of a display device 600 according to another exemplary embodiment of the present disclosure. Except that the display device 600 further includes a buffer pad PD, the display device 600 according to another exemplary embodiment of the present disclosure has the same configuration as the Figures 1 to 5B display device 100 shown. Therefore, a detailed description of the same configuration will not be provided.

[0105] Referring to Figure 6 , a plurality of buffer pads PD are provided between the display panel 120 and the frame 150. The plurality of buffer pads PD may be provided along the edge of the display panel 120. Each of the plurality of buffer pads PD may be provided between two of the plurality of first coupling members BD1. The thickness of each of the plurality of buffer pads PD may vary according to the distance between the display panel 120 and the frame 150. For example, when the distance between the display panel 120 and the frame 150 decreases, the thickness of the plurality of buffer pads PD may be reduced by being squeezed by the display panel 120 and the frame 150. The plurality of buffer pads PD may be made of an elastic material such that the thickness can vary according to the distance between the display panel 120 and the frame 150. For example, each buffer pad PD may be made of a foam pad having a plurality of holes or an elastic rubber pad, but is not limited thereto.

[0106] Hereinafter, for convenience of description, one of the plurality of buffer pads PD provided in the region where the distance between the display panel 120 and the frame 150 is the largest is defined as a first buffer pad PD1. In addition, one of the plurality of buffer pads PD provided in the region where the distance between the display panel 120 and the frame 150 is the smallest is defined as a second buffer pad PD2. However, this is only an example, and the present disclosure is not limited thereto.

[0107] Referring to Figure 7A , the first buffer pad PD1 among the plurality of buffer pads PD may be the buffer pad PD provided in the region where the distance between the display panel 120 and the frame 150 is the largest. Among the plurality of buffer pads PD, the first buffer pad PD1 may be pressed the least, and thus may have the maximum thickness PD1T. In a state where the first buffer pad PD1 is squeezed by the frame 150 and the display panel 120, the first buffer pad PD1 may push the display panel 120 and the first coupling member BD1 in a direction away from the frame 150. Moreover, the first buffer pad PD1 may push the frame 150 in a direction away from the display panel 120.

[0108] Among the plurality of first coupling members BD1, the first coupling member BD1 adjacent to the first buffer pad PD1 can be the farthest from the bottom surface of the plurality of grooves 151. The first buffer pad PD1 is disposed in the region where the interval between the frame 150 and the display panel 120 is the largest. Therefore, the first coupling member BD1 fixed to the display panel 120 is also the farthest from the bottom surface of the groove 151 of the frame 150 and protrudes the most from the groove 151. In addition, a part of the first coupling member SC1 inserted into the first fixing hole BDH1 of the first coupling member BD1 can have the shortest length.

[0109] In this case, the first buffer pad PD1 pushes the display panel 120 away from the frame 150. Therefore, the first coupling member SC1, a part of which is inserted into the first fixing hole BDH1 of the first coupling member BD1, can be pulled toward the display panel 120. Here, the head of the first coupling member SC1 is disposed on the rear surface of the frame 150, and the first coupling hole 152 through which the first coupling member SC1 passes is smaller than the head of the first coupling member SC1. Therefore, the head of the first coupling member SC1 cannot pass through the first coupling hole 152 toward the display panel 120, but can be fixed to the rear surface of the frame 150. Thus, the plurality of buffer pads PD push the display panel 120 and the first coupling member BD1 away from the frame 150 to fix the first coupling member SC1 so that the thread of the first coupling member SC1 does not move along the first coupling hole 152.

[0110] Refer to Figure 7B , the second buffer pad PD2 among the plurality of buffer pads PD can be the buffer pad PD disposed in the region where the interval between the display panel 120 and the frame 150 is the smallest. Among the plurality of buffer pads PD, the second buffer pad PD2 can be squeezed to the greatest extent, and thus can have the smallest thickness PD2T. In a state where the second buffer pad PD2 is squeezed by the frame 150 and the display panel 120, the second buffer pad PD2 can push the display panel 120 and the first coupling member BD1 in a direction away from the frame 150. In addition, the second buffer pad PD2 can push the frame 150 in a direction away from the display panel 120.

[0111] Among the plurality of first coupling members BD1, the first coupling member BD1 adjacent to the second buffer pad PD2 can be the closest to the bottom surface of the plurality of grooves 151. The second buffer pad PD2 is disposed in the region where the interval between the frame 150 and the display panel 120 is the smallest. Therefore, the first coupling member BD1 fixed to the display panel 120 can also be the closest to the bottom surface of the groove 151 of the frame 150. In addition, a part of the first coupling member SC1 inserted into the first fixing hole BDH1 of the first coupling member BD1 can have the maximum length.

[0112] A plurality of buffer pads PD of the display device 600 according to another exemplary embodiment of the present disclosure are filled in the space between the display panel 120 and the frame 150 to reduce the movement of the display panel 120. For example, when the frame 150 has a low flatness, a plurality of first coupling members BD1 and a plurality of first coupling members SC1 may be used to improve the flatness of the display panel 120. Here, when some of the first coupling members BD1 protrude outside the plurality of grooves 151 to adjust the flatness of the display panel 120, a space may be formed between the display panel 120 and the frame 150. In this case, the display panel 120 may move due to the space. Here, a plurality of buffer pads PD may be further provided between the frame 150 and the display panel 120 to fill the space between the frame 150 and the display panel 120. That is, the buffer pads PD provided between the frame 150 and the display panel 120 may support the display panel 120 to suppress the movement of the display panel 120. Therefore, in the display device 600 according to another exemplary embodiment of the present disclosure, the buffer pads PD are provided between the display panel 120 and the frame 150, so that the movement of the display panel 120 can be reduced.

[0113] In addition, a plurality of buffer pads PD of the display device 600 according to another exemplary embodiment of the present disclosure may reduce the movement of the plurality of first coupling members SC1 through the first coupling holes 152. Specifically, the plurality of first coupling members SC1 may pass through the first coupling holes 152 in the rear surface of the frame 150, and portions thereof may be respectively inserted into the first fixing holes BDH1 of the plurality of first engaging members BD1. For example, if the plurality of first coupling members SC1 are screws, their heads may be disposed on the rear surface of the frame 150, and the threads may be disposed in the plurality of grooves 151 of the frame 150 on the front surface of the frame 150. Here, the length of the portions of the plurality of first coupling members SC1 inserted into the first fixing holes BDH1 of the plurality of first engaging members BD1 may be adjusted to adjust the flatness of the display panel 120. Only a portion of the threads of the plurality of first coupling members SC1 may be threadedly inserted into the first fixing holes BDH1 of the plurality of first engaging members BD1. In this case, the other portions of the threads that are not inserted into the first fixing holes BDH1 may move along the first coupling holes 152. In this case, even if the length of the portions of the first coupling members SC1 inserted into the first fixing holes BDH1 of the first engaging members BD1 is adjusted, the position of the first coupling members SC1 is changed. Therefore, the position of the first engaging member BD1 may be changed, and it may be difficult to adjust the flatness of the display panel 120. Here, a plurality of elastic buffer pads PD are provided to be squeezed between the display panel 120 and the frame 150, so that a force can be continuously applied to push the display panel 120 and the frame 150. That is, the display panel 120 and the first engaging member BD1 fixed to the display panel 120 may move in a direction away from the frame 150 through the plurality of buffer pads PD. In addition, the frame 150 may move in a direction away from the display panel 120 and the first engaging member BD1. Here, the threads of the plurality of first coupling members SC1 are coupled to the first fixing holes BDH1 of the first engaging member BD1, so that the plurality of first coupling members SC1 may be pulled along the first engaging member BD1 in a direction away from the frame 150. Here, the heads of the plurality of first coupling members SC1 are disposed on the rear surface of the frame 150, and the first coupling holes 152 are smaller than the heads of the first coupling members SC1. Therefore, the heads of the first coupling members SC1 cannot pass through the first coupling holes 152, but may be fixed to the rear surface of the frame 150. Therefore, since the buffer pads PD are provided between the display panel 120 and the frame 150, the movement of the portions of the first coupling members SC1 that are not inserted into the first fixing holes BDH1 through the first coupling holes 152 can be reduced. Moreover, the position of the first engaging member BD1 can be easily fixed.

[0114] Figure 8 is an exploded perspective view of a display device according to still another exemplary embodiment of the present disclosure. Figure 9A side view of a display device according to yet another exemplary embodiment of the present disclosure is shown. Figure 8 is a perspective view observed from the front surface of the display device 800, Figure 9 and is a side view of the display device 800 observed from the right side of the display device 800. For ease of description, Figure 8 only the frame 150, a plurality of first coupling members BD1, a plurality of second coupling members BD2, a plurality of adhesive members AD, cushion pads PD, and a plurality of panel magnets MG are shown. Figure 9 The illustration of the shield 160 is omitted. Except that the display device 800 further includes a plurality of second coupling members BD2 and a plurality of second coupling members SC2, Figure 8 and Figure 9 the display device 800 shown has a configuration substantially the same as that of Figure 6 and Figure 7A 、 Figure 7B the display device 600 shown. Therefore, a detailed description of the same configuration will not be provided.

[0115] Referring to Figure 8 , the plurality of coupling members include a plurality of first coupling members BD1 and a plurality of second coupling members BD2. The plurality of first coupling members BD1 have a configuration substantially the same as that of Figures 1 to 5B the first coupling member BD1 shown. The plurality of second coupling members BD2 are configured to couple the display panel 120 and the frame 150, attach the display device 800 to the wall portion 200, and also adjust the flatness of the display panel 120.

[0116] The plurality of first coupling members BD1 are configured to adjust the flatness of the display panel 120 during and after assembling the display panel 120 and the frame 150. The plurality of second coupling members BD2 are configured to adjust the initial flatness when the display panel 120 and the frame 150 are assembled. When assembling the display panel 120 and the frame 150, the plurality of first coupling members BD1 and the plurality of second coupling members BD2 can be mainly used to adjust the flatness of the display panel 120. Then, after assembling the display panel 120 and the frame 150, the plurality of first coupling members BD1 can be used to secondarily adjust the flatness of the display panel 120.

[0117] The plurality of second coupling members BD2 can be disposed on two side surfaces of each of the plurality of panel magnets MG in the plurality of holes 153 of the frame 150. Each of the plurality of panel magnets MG can be disposed between the plurality of second coupling members BD2. For example, one of the plurality of second coupling members BD2 can be in contact with the N pole of the panel magnet MG, and another second coupling member BD2 can be in contact with the S pole of the panel magnet MG. The plurality of second coupling members BD2 and the panel magnets MG disposed in a single hole 153 can be fixed to each other and can move together in the hole 153 of the frame 150.

[0118] A plurality of second coupling members BD2 may be made of a ferromagnetic material. The plurality of second coupling members BD2 made of a ferromagnetic material may attach the display device 800 to the wall portion 200. For example, when the display device 800 is brought into contact with the wall portion 200, magnetic field lines are induced among the plurality of panel magnets MG, the plurality of second coupling members BD2, and the wall portion 200. Accordingly, the display device 800 may be fixed to the wall portion 200. Accordingly, the plurality of second coupling members BD2 may be used to adjust the flatness of the display panel 120 and attach the display device 800 to the wall portion 200.

[0119] In the drawings, the plurality of second coupling members BD2 are illustrated as ferromagnetic materials provided on two side surfaces of each of the plurality of panel magnets MG. However, the plurality of second coupling members BD2 may be inserted into other holes 153 of the frame 150 in which the plurality of panel magnets MG are not provided, or may be made of a rigid material instead of a ferromagnetic material. However, the present disclosure is not limited thereto.

[0120] The plurality of second coupling members BD2 include second fixing holes BDH2 coupled to the plurality of second coupling members SC2. The plurality of second coupling members BD2 may be inserted into the plurality of holes 153 of the frame 150 and coupled to the plurality of second coupling members SC2. Here, the plurality of second coupling members BD2 may be coupled to the second coupling members SC2 in a state where the plurality of second coupling members BD2 are disposed within the plurality of holes 153 of the frame 150. The second fixing holes BDH2 are configured to fix the plurality of second coupling members BD2 and the plurality of second coupling members SC2, and may be formed in a side surface of the second coupling member BD2 corresponding to an outer surface of the frame 150. For example, the second coupling member SC2 may be a screw having a thread, and the second fixing hole BDH2 of the second coupling member BD2 may be a screw hole having a thread on an inner circumferential surface.

[0121] The frame 150 includes a plurality of second coupling holes 854. The plurality of second coupling holes 854 are formed in an outer surface of the frame 150 and may communicate with the plurality of holes 153 of the frame 150. The plurality of second coupling holes 854 allow the plurality of second coupling members SC2 to pass therethrough. The plurality of second coupling members SC2 may be inserted into the second fixing holes BDH2 of the second coupling member BD2 through the plurality of second coupling holes 854, where the second coupling member BD2 is inserted into the plurality of holes 153.

[0122] Here, the plurality of second coupling holes 854 are slotted holes that are longer than the second fixing holes BDH2 of the second coupling member BD2. The plurality of second coupling holes 854 may be formed to be longer than the plurality of first coupling holes 152 and may have a slotted shape. For example, one end of each of the plurality of second coupling holes 854 may be disposed adjacent to one surface of the frame 150 facing the display panel 120. In addition, the other end of each of the plurality of second coupling holes 854 may be disposed adjacent to the opposite surface of one surface of the frame 150. The second coupling member SC2 inserted into the plurality of second coupling holes 854 and the second coupling member BD2 including the second fixing hole BDH2 threadedly coupled to the second coupling member SC2 may move along the longitudinal direction of the second coupling holes 854.

[0123] A plurality of adhesive members AD are disposed between the plurality of first coupling members BD1 and the display panel 120 and between the plurality of second coupling members BD2 and the display panel 120. The adhesive member AD may be made of an adhesive material to fix the first coupling member BD1 and the second coupling member BD2 to the rear surface of the display panel 120. For example, the adhesive member AD may be a sticky acrylic double-sided tape, but is not limited thereto.

[0124] In addition, the second coupling holes 854 of the frame 150 are formed as slotted holes to adjust the flatness of the display panel 120, which will be described in detail Figure 9 below.

[0125] Hereinafter, for convenience of description, one of the plurality of second coupling members BD2 disposed in the region with the largest interval between the display panel 120 and the frame 150 is defined as the second coupling member BD2'. In addition, one of the plurality of second coupling members BD2 disposed in the region with the smallest interval between the display panel 120 and the frame 150 is defined as the second coupling member BD2". However, this is only an example, and the present disclosure is not limited thereto.

[0126] Referring to Figure 9 , one surface of the plurality of second coupling members BD2 is disposed on the same plane. Since the plurality of second coupling members BD2 are disposed on the same plane, the flatness of the display panel 120 attached to one surface of the plurality of second coupling members BD2 can also be improved.

[0127] Here, the coupling positions of the second fixing holes BDH2 of the second coupling member BD2 and the second coupling holes 854 may vary according to the flatness of the frame 150. For example, the plurality of second coupling members SC2 and the second fixing holes BDH2 of the plurality of second coupling members BD2 may be located at different positions between one end and the other end of the second coupling holes 854. The shortest distance from each of the plurality of second coupling members SC2 to one surface of the frame 150 may vary according to the flatness of the frame 150.

[0128] For example, if the frame 150 has uniform flatness, the connection positions of the second fixing hole BDH2 of the second coupling member BD2 and the second coupling hole 854 of the frame 150 can be the same. However, when the frame 150 is bent, the connection positions of the second coupling hole 854, which is a slot hole, and the second fixing hole BDH2 of the second coupling member BD2 can be different from each other. That is, the second coupling hole 854 of the frame 150 is a long slot hole, and thus, the second coupling member SC2 and the second fixing hole BDH2 can move longitudinally within the second coupling hole 854 along the longitudinal direction of the second coupling hole 854.

[0129] For example, referring to Figure 9 , the second coupling member BD2' provided in the region where the maximum interval X3 between the display panel 120 and the frame 150 is the largest can protrude the most from one surface of the frame 150. In the region where the maximum interval X3 between the display panel 120 and the frame 150 is the largest, the frame 150 is bent the most in the direction away from the display panel 120. In this region, the second coupling hole 854 of the frame 150 can be set to be relatively far from the display panel 120. In addition, in the region where the maximum interval X3 between the display panel 120 and the frame 150 is the largest, the second coupling member BD2' can protrude the most from the plurality of holes 153 of the frame 150 to flatly support the display panel 120. In this case, the second coupling hole 854 of the frame 150 can be set away from one surface of the second coupling member BD2'. In addition, one end of the second coupling hole 854 adjacent to one surface of the frame 150 can be set away from one surface of the second coupling member BD2'. Therefore, the second fixing hole BDH2 of the second coupling member BD2' provided in the region where the maximum interval X3 between the display panel 120 and the frame 150 is the largest can be provided adjacent to one end of the second coupling hole 854. In addition, the second coupling member SC2 that fixes the second coupling member BD2' and the frame 150 can be provided adjacent to one end of the second coupling hole 854.

[0130] In addition, the second coupling member BD2" disposed in the region where the gap X4 between the display panel 120 and the frame 150 is minimized may protrude the least from one surface of the frame 150. In the region where the gap X4 between the display panel 120 and the frame 150 is minimized, the frame 150 is bent the most toward the display panel 120. In this region, the second coupling hole 854 of the frame 150 may be disposed relatively close to the display panel 120. In addition, in the region where the gap X4 between the display panel 120 and the frame 150 is minimized, the second coupling member BD2" may protrude the least from the plurality of holes 153 of the frame 150. Moreover, one end of the second coupling hole 854 adjacent to one surface of the frame 150 may be disposed adjacent to one surface of the display panel 120 and the second coupling member BD2". Therefore, the second fixing hole BDH2 of the second coupling member BD2" disposed in the region where the gap X4 between the display panel 120 and the frame 150 is minimized may be disposed adjacent to the other end of the second coupling hole 854. In addition, the second coupling member SC2 for fixing the second coupling member BD2" and the frame 150 may be disposed adjacent to the other end of the second coupling hole 854.

[0131] Therefore, a plurality of second coupling members BD2 whose one surfaces are disposed in the same plane may be fixed to the second coupling holes 854 which are the slot holes of the frame 150. Accordingly, the flatness of the display panel 120 may be improved without being limited to the flatness of the frame 150.

[0132] In addition, the plurality of second coupling members BD2 and the frame 150 may be assembled on a flat plate to improve the flatness of the display panel 120. The flat plate is a table having a high flatness on one surface. The plurality of second coupling members BD2 may be disposed on the flat plate such that one surfaces of the plurality of second coupling members BD2 may be disposed in the same plane. In addition, in a state where the plurality of second coupling members BD2 are disposed in the same plane, the second coupling member SC2 may be inserted into the second coupling holes 854 which are slot holes to couple the plurality of second coupling members BD2 and the frame 150. While maintaining the flatness of the plurality of second coupling members BD2 to which the display panel 120 is attached, the plurality of second coupling members BD2 are fastened to the frame 150. Accordingly, regardless of the flatness of the frame 150, the flatness of the display panel 120 attached to the plurality of second coupling members BD2 may be improved.

[0133] In this case, the thicknesses of the plurality of second coupling members BD2 may be greater than the thickness of the frame 150. Considering the error range of the flatness of the frame 150 caused by tolerances during the manufacture of the frame 150, the thicknesses of the plurality of second coupling members BD2 may be designed to be greater than the thickness of the frame 150. If the second coupling members BD2 have the same thickness as the frame 150, when the frame 150 is bent, one surface of at least some of the plurality of second coupling members BD2 inserted into the plurality of holes 153 of the frame 150 is disposed within the plurality of holes 153. Accordingly, the second coupling members BD2 may not be attached to the display panel 120 and may not support the display panel 120 flatly. Accordingly, the thicknesses of the plurality of second coupling members BD2 are designed to be greater than the thickness of the frame 150 so that one surface of the second coupling members BD2 is not disposed inside the plurality of holes 153. In addition, the second coupling members BD2 may support the display panel 120 flatly.

[0134] In a display device 800 according to another exemplary embodiment of the present disclosure, a plurality of second coupling holes 854, which are slot holes, are formed in a side surface of the frame 150. In addition, the plurality of second coupling holes 854 are fastened to the plurality of second coupling members BD2. Accordingly, the flatness of the display panel 120 may be improved, regardless of the flatness of the frame 150. First, a plurality of holes 153 may be formed in the frame 150, and the plurality of second coupling members BD2 may be disposed inside the plurality of holes 153. Then, a second coupling member SC2 may be inserted into the plurality of second coupling holes 854 formed in the side surface of the frame 150 and a second fixing hole BDH2 formed in the side surface of the second coupling member BD2. Accordingly, the plurality of second coupling members BD2 may be fastened to the frame 150. Here, the second coupling holes 854 formed in the side surface of the frame 150 are slot holes. Accordingly, the second fixing holes BDH2 of the plurality of second coupling members BD2 and the second coupling member SC2 may move along a longitudinal direction of the second coupling holes 854. Accordingly, the plurality of second coupling members BD2 may be fastened to the frame 150 in a state where the flatness between the plurality of second coupling members BD2 is adjusted. Accordingly, the plurality of second coupling members BD2 are coupled to the frame 150 in a state where the flatness of each of the plurality of second coupling members BD2 is adjusted. Accordingly, the flatness of the display panel 120 may be improved, regardless of the flatness of the frame 150.
