[0038] Because this disclosure allows for various variations and multiple embodiments, specific embodiments will be illustrated in the accompanying drawings and described in detail in the written description. However, this is not intended to limit this disclosure to particular practices, and it should be understood that all changes, equivalents, and substitutions without departing from the spirit and scope of this disclosure are included herein.

[0039] It should be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, the first element discussed below may be referred to as the second element without departing from the scope of this disclosure. Similarly, the second element may also be referred to as the first element. In this disclosure, the singular form is intended to include the plural form (or meaning) as well, unless the context clearly indicates otherwise.

[0040] It will also be understood that the terms "comprising," "including," "having," etc., as used in this disclosure indicate the presence of the stated features, integrals, steps, operations, elements, components, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof. Furthermore, when a first portion, such as a member, component, plate, panel, etc., is on a second portion, the first portion may not only be "directly" on the second portion, but a third portion may be inserted between the first and second portions. Furthermore, in this disclosure, when a first portion, such as a member, component, plate, panel, etc., is formed on a second portion, the surface of the second portion on which the first portion is formed is not limited to the upper surface of the second portion, but may include other surfaces such as the side or lower surface of the second portion. Furthermore, when a first portion, such as a member, component, plate, panel, etc., is "below" the second portion, the first portion may not only be "directly" below the second portion, but a third portion may be inserted between the first and second portions.

[0041] As used herein, the terms “about” or “approximately” include the stated value and the average value within an acceptable range of deviations of a particular value, determined by a person skilled in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations of the stated value, or within ±30%, ±20%, ±10%, ±5% of the stated value.

[0042] Unless otherwise defined or implied herein, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It should also be understood that terms such as those defined in common dictionaries shall be interpreted as having a meaning consistent with their meaning in the context of the relevant technology and disclosure, and shall not be interpreted in an idealized or overly formal sense unless clearly defined herein.

[0043] In the following description, embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used for the same parts, and repeated descriptions of the same parts are omitted.

[0044] Figure 1 This is a schematic perspective view showing a panel flattening assembly according to an embodiment. Figure 2 It is shown Figure 1 A schematic exploded perspective view of a portion of a panel flattening component. Figure 3 It is shown Figure 1 A schematic diagram of an example of a panel flattening component.

[0045] refer to Figure 1 , Figure 2 and Figure 3 The panel flattening assembly PPA may include fixing components 10, 20, 30 and 40, support components SP1, SP2, SP3 and SP4, and displacement adjustment components AM1, AM2, AM3, AM4, AM5, AM6, AM7 and AM8.

[0046] In one embodiment, the panel planarization assembly (PPA) can be attached to the rear surface of the display panel (DP). The display panel (DP) may include a substrate and pixel structures and a backplane structure formed on the front surface of the substrate. Therefore, the panel planarization assembly (PPA) can be attached to the rear surface of the substrate.

[0047] The structure in which the panel flattening component PPA is attached to the display panel DP can be defined as panel component 100.

[0048] As the thickness of the display panel (DP) becomes thinner or smaller, the thickness of the substrate included in the display panel DP can be very small, for example, about 200 μm or less. For example, the substrate can be made into a plastic substrate, a transparent polymer organic substrate including polyimide, polyamide, etc.

[0049] Thin substrates have weak shape retention forces, and the shape of the substrate (and display panel DP) may unintentionally deform or bend during the manufacturing process or during use. Therefore, components or materials should be added to fix and maintain the shape of the display panel DP, including the substrate.

[0050] As a component used to fix the shape of the display panel (DP), a full-surface adhesive component such as tape or heat dissipation film can be used. The full-surface adhesive component can be attached to the entire rear surface of the display panel (DP) to help flatten the surface of the substrate of the display panel (DP).

[0051] However, due to the bonding surface of the all-surface adhesive component, the uneven surface roughness of the bonding surface may be visually identifiable through the front surface of the transparent substrate, and the uneven surface roughness may lead to poor visibility.

[0052] To fix the shape of the display panel DP while minimizing the visibility of this poor performance, the adhesive components can be attached only to a portion of the edge of the rear surface of the display panel DP. However, in this case, it may be difficult to maintain the flatness of the display panel DP due to issues such as the central portion of the display panel DP sinking due to gravity, step differences (or height differences) between the adhesive components, etc.

[0053] The panel flattening assembly PPA according to an embodiment may include structures for improving the aforementioned problems. Hereinafter, the description will assume that the planar shape of the display panel DP is rectangular. However, this is an example, and the planar shape of the display panel DP is not limited thereto. The positions of the fixing components 10, 20, 30, and 40 attached to the display panel DP can vary depending on the planar shape of the display panel DP.

[0054] In this embodiment, the first to fourth fixing components 10, 20, 30 and 40 can be respectively disposed at the first to fourth corners on the rear surface of the display panel DP. For example, the second corner can be the corner adjacent to the first corner in the first direction DR1, the third corner can be the corner adjacent to the first corner in the second direction DR2, and the fourth corner can be the corner adjacent to the second corner in the second direction DR2.

[0055] The second direction DR2 can be different from the first direction DR1. For example, in a plan view, the second direction DR2 can be a direction perpendicular to the first direction DR1. The third direction DR3 can be a direction perpendicular to both the first direction DR1 and the second direction DR2. For example, the third direction DR3 can be a direction perpendicular to the rear surface of the display panel DP.

[0056] The first to fourth fixing components 10, 20, 30, and 40 can be bonded or joined to the rear surface of the display panel DP by means of adhesive members or the like. The displacement of the first to fourth fixing components 10, 20, 30, and 40 can be controlled by adjusting the displacement adjusting members AM1, AM2, AM3, AM4, AM5, AM6, AM7, and AM8 respectively. By controlling the displacement of the first to fourth fixing components 10, 20, 30, and 40, tension can be applied to the display panel DP, and the display panel DP can be flattened.

[0057] In an embodiment, the first fixing component 10 may include a first fixing member FM1 and a second fixing member FM2. The first fixing component 10 may also include a third fixing member FM3. Figure 2 The first fixing component 10 and other components connected thereto are shown, and the second to fourth fixing components 20, 30 and 40 and the first fixing component 10 may have substantially the same or similar configurations, except that they differ only in their arrangement.

[0058] In this embodiment, the first fixing member FM1, the second fixing member FM2, and the third fixing member FM3 may comprise metal or plastic materials. However, this is an example, and the materials of the first fixing member FM1, the second fixing member FM2, and the third fixing member FM3 are not limited thereto, and may include various materials capable of transmitting tension to the display panel DP without separating from the display panel DP.

[0059] In this embodiment, the first fixing member FM1, the second fixing member FM2, and the third fixing member FM3 may have a rectangular planar shape. However, this is just an example, and the planar shape of the first fixing member FM1, the second fixing member FM2, and the third fixing member FM3 is not limited thereto. For example, the first fixing member FM1, the second fixing member FM2, and the third fixing member FM3 may have any shape, as long as they have a structure that allows the display panel DP to be pulled straight.

[0060] The first fixing member FM1 can be directly attached to a first corner on the rear surface of the display panel DP. For example, the first fixing member FM1 can be attached to the display panel DP by tape, resin, etc., or by a process such as bonding.

[0061] The second fixing member FM2 can be set on the first fixing member FM1, and the third fixing member FM3 can be set on the second fixing member FM2.

[0062] The first fixing member FM1 may include a first fastening hole H1 and a second fastening hole H2. The second fixing member FM2 may include a third fastening hole H3 that overlaps with the first fastening hole H1 on the third direction DR3 and a fourth fastening hole H4 that overlaps with the second fastening hole H2 on the third direction DR3.

[0063] like Figure 2 As shown, the first fixing member FM1 and the second fixing member FM2 can be connected (or linked) by the first fastening screw TM1 and the second fastening screw TM2. The first fastening screw TM1 can be connected to the third fastening hole H3 and the first fastening hole H1, and the second fastening screw TM2 can be connected to the fourth fastening hole H4 and the second fastening hole H2.

[0064] However, this is just an example, and the connection between the first fixing member FM1 and the second fixing member FM2 is not limited to this. For example, the first fixing member FM1 and the second fixing member FM2 can be connected by adhesive material or by another type of fastening member.

[0065] In an embodiment, the second fixing member FM2 may further include a fifth fastening hole H5 and a sixth fastening hole H6. The third fixing member FM3 may include a seventh fastening hole H7 overlapping the fifth fastening hole H5 on the third direction DR3 and an eighth fastening hole H8 overlapping the sixth fastening hole H6 on the third direction DR3. The second fixing member FM2 and the third fixing member FM3 may be connected by a third fastening screw TM3 and a fourth fastening screw TM4.

[0066] The third fastening screw TM3 can be connected to the fifth fastening hole H5 and the seventh fastening hole H7, and the fourth fastening screw TM4 can be connected to the sixth fastening hole H6 and the eighth fastening hole H8. However, this is just an example, and the connection of the second fastening member FM2 and the third fastening member FM3 is not limited to this.

[0067] The second to fourth fixing components 20, 30, and 40, as well as the first fixing component 10, may be substantially the same configuration. The second fixing component 20 may include the first to third fixing members FM1b, FM2b, and FM3b. The second fixing component 20 may have a shape that is symmetrical with respect to the axis in the second direction DR2 to the shape of the first fixing component 10.

[0068] The third fixing component 30 may include the first fixing member to the third fixing member FM1c, FM2c and FM3c. The third fixing component 30 may have a shape that is symmetrical with respect to the axis on the first direction DR1 and the shape of the first fixing component 10.

[0069] The fourth fixing component 40 may include the first fixing member to the third fixing member FM1d, FM2d and FM3d. The fourth fixing component 40 may have a shape that is symmetrical with respect to the axis on the first direction DR1 and the shape of the second fixing component 20.

[0070] The first support member SP1 may be disposed between the first fixing component 10 and the second fixing component 20. The first support member SP1 may be spaced apart from the display panel DP. The first support member SP1 may have a rod shape extending in the first direction DR1. For example, the first support member SP1 may have a cylindrical or polygonal column shape extending in the first direction DR1.

[0071] According to an embodiment, the two ends of the first support member SP1 may include fastening holes, and the first displacement adjusting member AM1 and the third displacement adjusting member AM3 are respectively connected to the fastening holes. For example, the first displacement adjusting member AM1 may connect the first fixing component 10 and the first support member SP1, and the third displacement adjusting member AM3 may connect the second fixing component 20 and the first support member SP1.

[0072] The first support member SP1 may be made of metal or plastic. However, this is just an example, and the material of the first support member SP1 is not limited to this.

[0073] The second to fourth support members SP2, SP3 and SP4, as well as the first support member SP1, may comprise substantially the same material and may have similar shapes.

[0074] The second support member SP2 can be disposed between the first fixing component 10 and the third fixing component 30. The second support member SP2 can be spaced apart from the display panel DP. The two ends of the second support member SP2 can be connected to the second displacement adjusting component AM2 and the fourth displacement adjusting component AM4, respectively.

[0075] The third support member SP3 can be disposed between the third fixing component 30 and the fourth fixing component 40. The third support member SP3 can be spaced apart from the display panel DP. The two ends of the third support member SP3 can be connected to the fifth displacement adjustment component AM5 and the sixth displacement adjustment component AM6, respectively.

[0076] The fourth support member SP4 can be disposed between the second fixing component 20 and the fourth fixing component 40. The fourth support member SP4 can be spaced apart from the display panel DP. The two ends of the fourth support member SP4 can be connected to the seventh displacement adjustment member AM7 and the eighth displacement adjustment member AM8, respectively.

[0077] The first displacement adjusting member AM1 can extend to the first fixing component 10. The first displacement adjusting member AM1 can adjust the displacement of the first fixing component 10. Therefore, the distance between the first fixing component 10 and the first end of the first support member SP1 can be adjusted.

[0078] The first displacement adjustment component AM1 may be made of metal or plastic.

[0079] In an embodiment, such as Figure 2 As shown, the first displacement adjusting member AM1 may include a first screw member SCR1. The first screw member SCR1 may include a protrusion PRP1 projecting toward the second fixing assembly 20 in a first direction DR1. At least a portion of the protrusion PRP1 may be inserted into and engaged with a fastening hole included in the first end of the first support member SP1.

[0080] In an embodiment, the first fixing member FM1 and the second fixing member FM2 may each include a portion of a first screw member SCR1 inserted into recesses GR1 and GR2 therein. The first screw member SCR1 may be inserted between recesses GR1 and GR2.

[0081] The grooves GR1 and GR2 can restrict the movement of the first screw SCR1 within the first fixing assembly 10, except for the rotation of the first screw SCR1. Therefore, when the first screw SCR1 rotates to loosen or tighten from the first support member SP1, the displacement of the entire first fixing assembly 10 together with the first screw SCR1 can be changed.

[0082] By rotating the first screw component SCR1, the first screw component SCR1 and the first fixing component 10 can move together in the first direction DR1 or in the opposite direction to the first direction DR1, and the distance between the first fixing component 10 and the first end of the first support component SP1 can be adjusted.

[0083] For example, when the first screw SCR1 is rotated counterclockwise to loosen from the first support member SP1, the first force F1 can also be applied to the first fixing component 10 in the opposite direction to the first direction DR1, and the first fixing component 10 can be pushed in the opposite direction to the first direction DR1. Therefore, the display panel DP attached to the first fixing component 10 can be pulled by the first force F1 in the opposite direction to the first direction DR1.

[0084] In this embodiment, the second displacement adjusting member AM2 to the eighth displacement adjusting member AM8 can also be implemented in the form of screws. The second fixing component to the fourth fixing component 20, 30 and 40 and the third displacement adjusting member AM3 to the eighth displacement adjusting member AM8 can have substantially the same or similar connection relationship with the first fixing component 10 and the first screw SCR1.

[0085] For example, the third displacement adjusting member AM3 and the seventh displacement adjusting member AM7 can be connected to the second fixing component 20, the fourth displacement adjusting member AM4 and the fifth displacement adjusting member AM5 can be connected to the third fixing component 30, and the sixth displacement adjusting member AM6 and the eighth displacement adjusting member AM8 can be connected to the fourth fixing component 40.

[0086] In one embodiment, the third displacement adjusting member AM3 can be coupled to the second fixing assembly 20 to have a shape symmetrical to the first displacement adjusting member AM1. The third displacement adjusting member AM3 may include a screw (hereinafter referred to as the third screw) identical to the first screw SCR1. The third displacement adjusting member AM3 can be inserted into and coupled to a fastening hole included in the second end of the first support member SP1. For example, the third screw may include a protrusion projecting into the first fixing assembly 10. The protrusion can be coupled to the fastening hole at the second end of the first support member SP1.

[0087] By rotating the third screw, the third screw and the second fixing assembly 20 can move together in the first direction DR1 or in the opposite direction to DR1, and the distance between the second fixing assembly 20 and the second end of the first support member SP1 can be adjusted. For example, when the third screw is rotated counterclockwise to loosen from the first support member SP1, a second force F2 can also be applied to the second fixing assembly 20 in the first direction DR1, and the second fixing assembly 20 can be pushed in the first direction DR1. Therefore, the display panel DP attached to the second fixing assembly 20 can be pulled in the first direction DR1 by the second force F2.

[0088] In this embodiment, the second displacement adjusting member AM2 may be disposed between the second fixing member FM2 and the third fixing member FM3. The second displacement adjusting member AM2 may protrude in the second direction DR2. The second displacement adjusting member AM2 can adjust the distance between the first fixing member 10 and the first end of the second support member SP2 by adjusting the displacement of the first fixing member 10.

[0089] The second displacement adjusting member AM2 may include a second screw SCR2 protruding in the second direction DR2. The second screw SCR2 may include a protrusion PRP2 protruding into the third fixing assembly 30 and connected to the second support member SP2.

[0090] In this embodiment, the second fixing member FM2 and the third fixing member FM3 may each include recesses GR3 and GR4 into which a portion of the second screw SCR2 is inserted, thereby restricting the movement of the second screw SCR2 within the first fixing assembly 10, except for rotation of the second screw SCR2. The second screw SCR2 may be inserted between recesses GR3 and GR4. Therefore, when the second screw SCR2 rotates to loosen or tighten from the second support member SP2, the displacement of the entire first fixing assembly 10 together with the second screw SCR2 can be changed.

[0091] By rotating the second screw component SCR2, the second screw component SCR2 and the first fixing component 10 can move together in the second direction DR2 or in the opposite direction to the second direction DR2, and the distance between the first fixing component 10 and the first end of the second support component SP2 can be adjusted.

[0092] For example, such as Figure 1 and Figure 3 As shown, when the second screw SCR2 is rotated counterclockwise to loosen from the second support member SP2, the third force F3 can also be applied to the first fixing component 10 in the opposite direction to the second direction DR2, and the first fixing component 10 can be pushed in the opposite direction to the second direction DR2. Therefore, the display panel DP attached to the first fixing component 10 can be pulled by the third force F3 in the opposite direction to the second direction DR2.

[0093] Similarly, the fourth force F4 can be applied to the third fixing component 30 in the second direction DR2 through the displacement control of the fourth displacement adjustment member AM4, and the third fixing component 30 can be pushed in the second direction DR2. Therefore, the display panel DP attached to the third fixing component 30 can be pulled in the second direction DR2 by the fourth force F4.

[0094] As described above, the first displacement adjustment member AM1 to the eighth displacement adjustment member AM8 can be implemented as screws, and the displacements of the first fixing component to the fourth fixing component 10, 20, 30 and 40 can be adjusted by rotating the screws. Therefore, when the display panel DP is pulled in four directions by the first force F1 to the fourth force F4, the substrate and the surface of the display panel DP including the substrate can be made uniformly flat.

[0095] Since the area of ​​the first to fourth fixing components 10, 20, 30 and 40, which are attached to the rear surface of the display panel DP to fix the shape of the display panel DP, can be minimized, the effect of surface roughness can be minimized. In addition, since the displacement of the fixing components 10, 20, 30 and 40 can be adjusted individually, the surface of the display panel DP can be made flat in an optimal state under various conditions.

[0096] Figure 4 This is a schematic diagram illustrating an example of a panel flattening component.

[0097] like Figure 4 As shown, the same reference numerals are used for reference. Figure 1 and Figure 2 The components will be described, and repeated descriptions of these components will be omitted.

[0098] refer to Figure 4 The panel flattening assembly PPA1 may include fixing components 10, 20, 30 and 40, support members SP1, SP2, SP3 and SP4, and screws SCR1, SCR2, SCR3 and SCR4.

[0099] The first screw component SCR1 can be connected between the first fixing component 10 and the first end of the first support member SP1. The second screw component SCR2 can be connected between the second fixing component 20 and the second end of the first support member SP1.

[0100] The first force F1 and the second force F2 can be applied to the display panel DP by rotating the first screw SCR1 and the second screw SCR2.

[0101] The third screw component SCR3 can be connected between the first end of the third fixing component 30 and the third support component SP3. The fourth screw component SCR4 can be connected between the second end of the fourth fixing component 40 and the third support component SP3.

[0102] The third force F3 and the fourth force F4 can be applied to the display panel DP by rotating the third screw SCR3 and the fourth screw SCR4.

[0103] In this embodiment, the second support member SP2 can be directly connected to the first fixing component 10 and the third fixing component 30. Therefore, the second support member SP2 can be used solely to support the first fixing component 10, the third fixing component 30, and the display panel DP.

[0104] Similarly, the fourth support member SP4 can be directly connected to the second fixing component 20 and the fourth fixing component 40. Therefore, the fourth support member SP4 can be used solely to support the second fixing component 20, the fourth fixing component 40, and the display panel DP.

[0105] Therefore, a pulling force can be applied to the display panel DP in both the first direction DR1 and in the direction opposite to the first direction DR1. Figure 1Compared to the panel flattening assembly PPA, the panel flattening assembly PPA1 is more advantageous in terms of manufacturing cost. The direction of the force applied to the display panel DP can be freely controlled according to the arrangement and / or position of the screws SCR1, SCR2, SCR3, and SCR4, and the fixing components 10, 20, 30, and 40.

[0106] Figure 5 This is a schematic diagram illustrating an example of a panel flattening component.

[0107] like Figure 5 As shown, the same reference numerals are used for reference. Figure 1 , Figure 2 and Figure 4 The components will be described, and repeated descriptions of these components will be omitted.

[0108] refer to Figure 5 The panel flattening assembly PPA2 may include fixing components 10, 20, 30 and 40, support members SP1 and SP2, and spring members SPR1, SPR2, SPR3 and SPR4.

[0109] For example, refer to Figure 1 The described displacement adjusting components may include spring components SPR1, SPR2, SPR3, and SPR4, respectively. Besides... Figure 4 The screw components SCR1, SCR2, SCR3, and SCR4 are replaced by spring components SPR1, SPR2, SPR3, and SPR4. Figure 5 The embodiments can be related to Figure 4 The panel flattening component PPA1 is basically the same.

[0110] The first spring member SPR1 can be connected between the first fixing component 10 and the first end of the first support member SP1. The second spring member SPR2 can be connected between the second fixing component 20 and the second end of the first support member SP1.

[0111] The first spring member SPR1 can be inserted between the first fixing component 10 and the first end of the first support member SP1 by the elastic force of the first spring member SPR1. The first force F1 that pushes the first fixing component 10 in the first direction DR1 or in the direction opposite to the first direction DR1 can be generated by the restoring force of the first spring member SPR1.

[0112] The second force F2, the third force F3, and the fourth force F4 can be generated by the restoring force of each of the second spring member SPR2, the third spring member SPR3, and the fourth spring member SPR4 in the first direction DR1 or in the direction opposite to the first direction DR1.

[0113] According to the embodiment, it can be omitted Figure 1The second support member SP2 and the fourth support member SP4 can reduce manufacturing costs.

[0114] As mentioned above, displacement adjustment components can be made from various materials and screws.

[0115] Figure 6 This is a schematic diagram illustrating a display module according to an embodiment of the present disclosure.

[0116] refer to Figure 1 and Figure 6 The display module DM may include a display panel DP, a panel flattening assembly PPA, a circuit board CP, and a back cover BCV. The panel flattening assembly PPA can also be replaced by the panel flattening assembly PPA1 or panel flattening assembly PPA2 described above.

[0117] Display panel (DP) may include a thin substrate, a pixel structure, and a backplane structure formed on the entire surface of the substrate.

[0118] A panel flattening assembly (PPA) can be attached to the rear surface of the substrate of the display panel (DP). The panel flattening assembly (PPA) may include fixing components 10, 20, 30, and 40, support members SP1, SP2, SP3, and SP4, and displacement adjustment members AM1, AM2, AM3, AM4, AM5, AM6, AM7, and AM8. The panel flattening assembly (PPA) flattens the surface of the display panel (DP) and fixes its shape.

[0119] Since it has already been referenced Figures 1 to 5 The panel flattening assembly PPA, panel flattening assembly PPA1 and panel flattening assembly PPA2 are described in detail, so repeated descriptions of them will be omitted.

[0120] The circuit board CP can be positioned on or below the panel flattening assembly PPA. For example, the circuit board CP can be positioned below the panel flattening assembly PPA. The circuit board CP can be configured to accommodate or mount external circuitry, ICs, etc., for driving the display panel DP. For example, processors, storage devices, etc., can be mounted or connected to the circuit board CP.

[0121] The back cover BCV can be configured to cover the rear surface of the display panel (DP), the panel flattening assembly (PPA), and the circuit board (CP). The back cover BCV protects internal components from external contamination, foreign objects, impacts, etc.

[0122] The back cover BCV can be arranged to surround and protect the panel flattening assembly PPA and the circuit board CP. The back cover BCV can cover the side surface of the display panel DP. However, this is just an example, and the shape of the back cover BCV is not limited to this.

[0123] Figure 7 It shows that it includes the application Figure 1 A schematic diagram illustrating an example of a multi-screen display device with a panel flattening component.

[0124] refer to Figure 1 and Figure 7 A multi-screen display device (TD, also known as a tiled display) may include panel assemblies 100A, 100B, 100C and 100D arranged in a matrix.

[0125] Each of the display panels DP of panel assemblies 100A, 100B, 100C, and 100D can display an image individually or divide and display images. The display panels DP may include display panels of the same type, structure, size, or method, but this disclosure is not limited thereto.

[0126] Panel assemblies 100A, 100B, 100C and 100D can be physically connected via a housing (not shown) to form a multi-screen display device TD.

[0127] Each of panel assemblies 100A, 100B, 100C, and 100D may include a panel flattening assembly PPA (see [link to PPA]). Figure 1 The panel flattening assembly PPA includes a fixing component 10 and a support component SP.

[0128] In an embodiment, at least one of the fixing components 10 may include a magnetic material. Mutual attraction can act between adjacent fixing components 10. Therefore, the panel flattening assembly PPA (see...) Figure 1 This can facilitate the physical connection between panel assemblies 100A, 100B, 100C and 100D in a multi-screen display device TD.

[0129] As described above, the panel flattening assembly according to the embodiment and the display module including the panel flattening assembly may include a fixing assembly attached to the rear surface of the display panel with a minimal area (e.g., corner area). Therefore, the effect of surface roughness caused by the fixing assembly can be minimized, and thus image quality can be improved. Furthermore, since the displacement of the fixing assembly is individually adjusted by the force generated by the displacement adjusting member, the surface of the display panel can be substantially flat and fixed in an optimal state under various conditions. Therefore, shape defects such as deformation and warping that occur depending on the assembly state of the display panel can be improved without degrading image quality.

[0130] However, the effects of this disclosure are not limited to those described above, and various extensions can be made without departing from the spirit and scope of this disclosure.

[0131] As described above, embodiments of the present disclosure have been described with reference to the accompanying drawings. However, those skilled in the art will understand that various modifications and changes can be made to the present disclosure without departing from its spirit and scope.
