[0002] This application claims priority and interest in Korean Patent Application No. 10-2020-0189661, filed on December 31, 2020, with the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to a display device. Background Technology

[0004] Display devices include liquid crystal displays (LCDs), plasma display panels (PDPs), organic light-emitting diode (OLED) devices, field-effect displays (FEDs), electrophoretic display devices, etc.

[0005] With the development of display devices, the demand for flat panel displays with ultra-large screens is also increasing. However, the size of flat panel displays with ultra-large screens increases or their image quality deteriorates.

[0006] In order to achieve an ultra-large flat panel display device without unnecessarily increasing the size or degrading the image quality, a tiled display device has been proposed in which flat panel display panels are connected in a tiled manner to realize a large screen.

[0007] In tiled display devices where flat panel displays are connected, if the spacing between adjacent display panels is widened or not constant, areas where no image is displayed may be visible, thus potentially degrading the display quality.

[0008] The information disclosed in this background section is only intended to enhance the understanding of the background of the technology, and therefore may contain information that does not form prior art that may be known to a person skilled in the art. Summary of the Invention

As will be understood by those skilled in the art, the described embodiments can be modified in various ways without departing from the spirit and scope of this disclosure.

[0046] To clearly describe the implementation, parts that may be irrelevant to the description may be omitted, and throughout the specification, the same or similar components are indicated by the same reference numerals.

[0047] Furthermore, the dimensions and thicknesses of each element are arbitrarily shown in the accompanying drawings for ease of description, and this disclosure is not necessarily limited to the elements shown in the drawings. The thicknesses of layers, films, panels, areas, regions, etc., are exaggerated in the drawings for clarity and ease of description.

[0048] As used in this article, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0049] In the specification and claims, the term "and / or" is intended to include any combination of the terms "and" and "or" for the purposes of its meaning and interpretation. For example, "A and / or B" can be understood to mean "A, B, or A and B". The terms "and" and "or" can be used in a combined or separate sense and can be understood as equivalent to "and / or".

[0050] In the specification and claims, the phrase "at least one of" is intended to include the meaning of "at least one selected from the group consisting of" for purposes of meaning and interpretation. For example, "at least one of A and B" can be understood to mean "A, B, or A and B".

[0051] It will 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, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element, without departing from the scope of this disclosure.

[0052] It will be understood that when an element such as a layer, film, region, area, or substrate is referred to as being "on" another element, it may be directly on said other element, or an intervening element may be present. Conversely, when an element is referred to as being "directly" on another element, no intervening element is present. Furthermore, in the specification, the terms "on" or "above" mean located on or below the object portion, and do not necessarily mean located on the upper side of the object portion based on the direction of gravity.

[0053] The term “overlapping” or “overlapping” means that the first object may be above or below the second object, or on one side of the second object, and vice versa. Additionally, the term “overlapping” may include layer, stack, face or facing, extend, cover or partially cover, or any other suitable term as would be understood and appreciated by one of ordinary skill in the art.

[0054] When an element is described as “not overlapping” or “will not overlap” with another element, this may include elements spaced apart from each other, offset from each other, or arranged side by side, or any other suitable terminology as would be understood and appreciated by one of ordinary skill in the art.

[0055] The terms "face" and "facing" mean that the first element can be directly or indirectly opposite the second element. In cases where a third element is inserted between the first and second elements, the first and second elements can be understood as being indirectly opposite each other, although still facing each other.

[0056] Furthermore, unless explicitly stated otherwise, the words “comprise” and its variations (such as “comprises” or “comprising”), “include” and / or “including”, “has”, “have” and / or “having” and their variations shall be understood to imply inclusion of the stated element, but not to exclude any other element.

[0057] Furthermore, throughout the specification, the phrases “in a plan view” or “on a plane” refer to the target portion viewed from above, and the phrases “in a sectional view” or “on a section” refer to the section formed by vertically cutting the target portion, viewed from the side.

[0058] Furthermore, throughout the specification, “connection” means not only when two or more components are directly connected, but also when two or more components are indirectly connected through other components, and when they are physically or electrically connected. It can also be referred to by different names depending on location or function, and can also refer to the situation where the various parts that can be substantially integrated can be linked to each other.

[0059] As used herein, “about” or “approximately” includes the value and the average of the values ​​within an acceptable range of deviations from the particular value, as determined by a person of ordinary skill in the art when considering 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, or within ±30%, 20%, ±10%, ±5% of the value.

[0060] Unless otherwise specified, 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 will 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 art and shall not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

The display panel DP includes display panels DP11, DP12, DP13, DP21, DP22, DP23, DP31, DP32 and DP33.

[0063] Display panels DP11, DP12, DP13, DP21, DP22, DP23, DP31, DP32, and DP33 can be arranged in a matrix along a first direction DR1 and a second direction DR2 perpendicular to the first direction DR1. For example, the first display panel DP11, the second display panel DP12, and the third display panel DP13 are arranged in a row along the first direction DR1; the fourth display panel DP21, the fifth display panel DP22, and the sixth display panel DP23 are arranged in a row along the first direction DR1; and the seventh display panel DP31, the eighth display panel DP32, and the ninth display panel DP33 are arranged in a row along the first direction DR1.

[0064] Display panels DP11, DP12, DP13, DP21, DP22, DP23, DP31, DP32, and DP33 may form a first interval SP1. Display panels DP11, DP12, DP13, DP21, DP22, DP23, DP31, DP32, and DP33 may be extended such that their flat areas are increased by drive columns when driven, and thus, in order to prevent adjacent display panels from colliding and being damaged due to their expansion, they may be configured to have at least a first interval SP1 between them.

[0065] In the illustrated embodiment, for illustrative purposes, the first interval SP1 between adjacent display panels is shown as relatively wide, and the first interval SP1 can be a very small interval compared to the size of the display panels.

[0066] In the illustrated embodiment, the three display panels are arranged in a row along the first direction DR1 and the three display panels are arranged in a row along the second direction DR2. However, this is just an example and the implementation is not limited to this. The display panels may be arranged in a row along the first direction DR1 and the second direction DR2.

[0067] Reference Figure 6 Together Figure 2 Describes the frame 200 that supports the display panel DP.

[0068] refer to Figure 6 Together Figure 2The frame 200 supporting the display panel DP may include a rear frame CR, a first magnet M1, a side frame S and a frame connector SC, wherein the rear frame CR includes a first rear frame R1, R2, R3 and R4 and a second rear frame C1, C2, C3 and C4.

[0069] The first rear frames R1, R2, R3 and R4 include a first frame R1, a second frame R2, a third frame R3 and a fourth frame R4 extending along a first direction DR1, and the second rear frames C1, C2, C3 and C4 include a fifth frame C1, a sixth frame C2, a seventh frame C3 and an eighth frame C4 extending along a second direction DR2, while the first rear frames R1, R2, R3 and R4 and the second rear frames C1, C2, C3 and C4 may overlap each other along a third direction DR3.

[0071] In the first rear frames R1, R2, R3, and R4 and the second rear frames C1, C2, C3, and C4, a first magnet M1 is attached to or disposed on the first frame R1, fourth frame R4, fifth frame C1, and eighth frame C4 located at their edges. The first magnet M1 includes a first portion M11 extending in a direction perpendicular to the direction in which the first frame R1, fourth frame R4, fifth frame C1, and eighth frame C4 extend (e.g., a direction parallel to a first direction DR1 or a second direction DR2), and a second portion M12 extending from the first portion M11 in a direction parallel to a third direction DR3.

[0072] In the illustrated embodiment, a first magnet M1 is shown attached to or disposed on the first frame R1, fourth frame R4, fifth frame C1, and eighth frame C4 disposed at the edges of the first rear frames R1, R2, R3, and R4 and the second rear frames C1, C2, C3, and C4. However, the embodiment is limited to this, and the first magnet M1 may be attached to or disposed on at least some or a portion of the first rear frames R1, R2, R3, and R4 and the second rear frames C1, C2, C3, and C4.

[0076] In the following text, reference will be made to Figure 3A and Figure 3B Describe the combination of the rear frame CR and the first magnet M1.

[0077] refer to Figure 3A The first adhesive layer AL1 can be disposed between the rear frame CR and the first magnet M1 of the display device according to the embodiment, and the rear frame CR and the first magnet M1 can be connected or joined to each other through the first adhesive layer AL1.

[0078] The first magnet M1 may include a first portion M11 and a second portion M12. The first portion M11 extends in a direction perpendicular to the direction in which the rear frame CR attached to or disposed on the first magnet M1 extends (e.g., a direction parallel to the first direction DR1 or the second direction DR2). The second portion M12 extends from the first portion M11 in a direction parallel to the third direction DR3.

[0079] The first adhesive layer AL1 can be disposed between the rear frame CR and the first part M11 of the first magnet M1.

[0080] refer to Figure 3B , and according to Figure 3AThe display device of the embodiment shown differs from that of the rear frame CR, which may further include an extension CR1. The extension CR1 of the rear frame CR may include a portion extending in a direction perpendicular to the direction in which the rear frame CR extends (e.g., a first direction DR1 or a second direction DR2) and bending in a third direction DR3, and a first magnet M1 is disposed on the extension CR1 of the rear frame CR. In other words, the extension CR1 may include a first portion extending from the rear frame CR in a direction perpendicular to the direction in which the rear frame CR extends (e.g., a first direction DR1 or a second direction DR2), and a second portion extending from the first portion in the third direction DR3. The first magnet M1 may be attached to or disposed on the extension CR1 of the rear frame CR.

[0081] The extension CR1 of the rear frame CR can be configured to surround the first part M11 and the second part M12 of the first magnet M1.

[0082] Thus, by further including the extension CR1 surrounding the first magnet M1 of the rear frame CR, the first magnet M1 and the rear frame CR can be stably connected.

[0083] Now refer to Figures 4 to 6 Describe the rear surfaces of display panels DP11, DP12, DP13, DP21, DP22, DP23, DP31, DP32 and DP33.

[0084] refer to Figures 4 to 6 The second magnet M2 is attached to or disposed on the rear surface of the display panel DP, which includes display panels DP11, DP12, DP13, DP21, DP22, DP23, DP31, DP32, and DP33. The second magnet M2 may be configured to overlap with the first magnet M1 along a direction parallel to the direction in which the first portion M11 of the first magnet M1 extends (e.g., along a first direction DR1 or a second direction DR2) and a third direction DR3.

[0085] refer to Figure 5 According to the embodiment, the display panel DP of the display device may include a first surface S1 for displaying images and a second surface S2 disposed in a direction opposite to the first surface S1. A second adhesive layer AL2 may be disposed between the second surface S2 of the display panel DP and the second magnet M2, and the second surface S2 of the display panel DP and the second magnet M2 may be connected or coupled to each other through the second adhesive layer AL2.

[0086] As described above, the second magnet M2 can overlap with the first magnet M1.

[0087] As an example, see reference Figure 5 Together Figure 3A and Figure 3B The second magnet M2 can overlap with the first portion M11 of the first magnet M1 along a third direction DR3, and simultaneously, the second magnet M2 can overlap with the second portion M12 of the first magnet M1 along a first direction DR1 or a second direction DR2. For example, the first portion M11 and the second portion M12 of the first magnet M1 can be configured to surround the lower surface and side surface of the second magnet M2.

[0088] The first magnet M1 and the second magnet M2 can have different polarities, and therefore, an attractive force can act between them.

[0089] In the following text, reference will be made to Figures 7 to 9 Describes the variation in the spacing between the display panels of the display device according to an embodiment. Figure 7 A schematic cross-sectional view of the display device in a first state according to an embodiment is shown. Figure 8 A schematic cross-sectional view of a second state of the display device according to an embodiment is shown, and Figure 9 A schematic cross-sectional view of the display device in a third state according to an embodiment is shown. Figure 7 , Figure 8 and Figure 9 It shows along Figure 1 A schematic cross-sectional view taken from line VI-VI.

[0090] Reference Figure 7 The first state in which no image is displayed is described. In the first state, display panels DP21, DP22, and DP23, which are arranged adjacent to each other, can be supported by second rear frames C1, C2, C3, and C4 and side frames S, and can be arranged to form a first interval SP1. First magnet M1 and second magnet M2 can be in a state where they are connected or joined to each other by attractive force, wherein the first magnet M1 is attached to or disposed on at least some or a portion of the second rear frames C1, C2, C3, and C4, and the second magnet M2 is attached to or disposed on at least some or a portion of the second surfaces S2 of the display panels DP21, DP22, and DP23, and the second magnet M2 is attached to or disposed on at least some or a portion of the second surfaces S2 of the display panels DP21, DP22, and DP23.

[0091] Reference Figure 8The second state in which the image is displayed is described. In the second state, heat can be generated from the display panels DP21, DP22, and DP23 due to the drive used for display, and due to this heat, the flat areas of the display panels DP21, DP22, and DP23 can be extended to widen. For example, when the display panel DP is driven and heat of about 50°C is generated, the display panel DP, which has a planar length of about 65 inches in the plan view, can be extended by about 0.1 mm.

[0092] Thus, the display panels DP21, DP22, and DP23, which are set to be adjacent to each other and extend due to heat, can be set to form a second interval SP2 between each other, and the second interval SP2 between the display panels DP21, DP22, and DP23, which are set to be adjacent to each other in the first state, can be narrower than the first interval SP1 between the display panels DP21, DP22, and DP23, which are set to be adjacent to each other in the first state.

[0093] Reference Figure 9 Describe the third state in which no image is displayed. In the second state, the display panels DP21, DP22, and DP23, which had stretched due to heat, shrink back to their original state as they cool in the third state in which no image is displayed.

[0094] By the attraction between the first magnet M1 and the second magnet M2, the fourth display panel DP21 and the sixth display panel DP23, which are disposed at the edge of the display device, point towards the fifth display panel DP22 to move in the fourth direction DR11 and the fifth direction DR12 oriented toward the center of the display device, so that the display panels DP21, DP22 and DP23 can be restored to form the first interval SP1 as in the first state, wherein the first magnet M1 is attached to at least some or a portion of C1 and C4 of the second rear frame C1, C2, C3 and C4 or disposed on at least some or a portion of C1 and C4 of the second rear frame C1, C2, C3 and C4, and the second magnet M2 is attached to at least some or a portion of the second surface S2 of the display panels DP21, DP22 and DP23 or disposed on at least some or a portion of the second surface S2 of the display panels DP21, DP22 and DP23.

[0095] According to the display device of this embodiment, when a first magnet M1 is attached to or disposed on the rear frame CR supporting the display panel DP and a second magnet M2 is attached to or disposed on the second surface S2 of the display panel DP, and when the display panel DP shrinks back to its original size after being stretched due to driving heat, the gap can be restored to the original gap by the attraction between the first magnet M1 and the second magnet M2. Thus, by preventing the gap between the display panels DP from increasing or becoming irregular, the display quality can be prevented from deteriorating due to the increase or irregularity of the gap between the display panels DP.

[0096] In the following text, reference will be made to Figure 10 and Figure 11 Together Figures 7 to 9 This describes the spacing between the display panels (DPs) of a display device. Figure 10 A schematic cross-sectional view of a display device of the related technology is shown, and Figure 11 A schematic top view of a display device related to the technology is shown.

[0097] In cases where the display panels DP21, DP22, and DP23, which have stretched due to heat, are cooled and reduced to their original state while in a state where no image is displayed, and in cases where the display device of the related art does not include a first magnet M1 attached to or disposed on the rear frame CR supporting the display panel DP, or a second magnet M2 attached to or disposed on the second surface S2 of the display panel DP, as in the case where the display panel DP has not been extended due to heat, or is disposed on the rear frame CR supporting the display panel DP, as in the case where the display device of the related art does not include a second magnet M1 attached to or disposed on the second surface S2 of the display panel DP, as in the case where the display panel DP has not been extended due to heat, or is disposed on the rear frame CR supporting the display panel DP, as in the case where the display panel DP has not been extended due to heat, or is disposed on the rear surface S2 of the display panel DP, as in the case where the display panel DP has not been extended due to heat, or is disposed on the rear frame CR supporting the display panel DP ...21, DP22, and DP23, which have extended due to heat, are cooled and reduced to their original state, and in the case where the display panel DP21, DP22, and DP23, which have not been extended due to heat, are cooled and reduced to their original state, and in the case where the display panel DP21, DP22, and DP23, which have not been extended due to heat, or is disposed on the rear frame CR supporting the display panel DP, or is disposed on the rear frame CR, or is disposed on the rear frame CR supporting the display panel DP, or is disposed on the rear surface S2 Figure 10 As shown, the fourth display panel DP21 and the sixth display panel DP23 can move on the sixth direction DR13 and the seventh direction DR14, which are opposite to the fourth direction DR11 and the fifth direction DR12. Therefore, the adjacent display panels DP21, DP22 and DP23 can be configured to form a third interval SP3, and the third interval SP3 can be wider than the first interval SP1.

[0098] refer to Figure 11When display panels DP11, DP12, DP13, DP21, DP22, DP23, DP31, DP32, and DP33 are cooled and reduced to their original state while they are not displaying an image, they can move along the first direction DR1 in the fourth direction DR11 and the fifth direction DR12 toward the center of the display device, and can move along the sixth direction DR13 and the seventh direction DR14, which are opposite directions to the fourth direction DR11 and the fifth direction DR12. Similarly, display panels DP11, DP12, DP13, DP21, DP22, DP23, DP31, DP32, and DP33 can move along the second direction DR2 in the eighth direction DR21 and the ninth direction DR22 toward the center of the display device, and can move along the tenth direction DR23 and the eleventh direction DR24, which are opposite directions to the eighth direction DR21 and the ninth direction DR22.

[0099] Therefore, according to the decreasing direction of display panels DP11, DP12, DP13, DP21, DP22, DP23, DP31, DP32, and DP33, the spacing between adjacent display panels can form a relatively wide spacing SPa or a relatively narrow spacing SPb. As described above, since the spacing between adjacent display panels is irregularly formed into a wide spacing SPa or a narrow spacing SPb depending on the position, the spacing of the display panels can be set irregularly.

[0100] like Figure 10 and Figure 11 As shown, in a display device of the related art, when a display panel that has stretched due to heat is cooled and reduced to its original state while it is not displaying an image, the spacing between adjacent display panels may increase, or the spacing between adjacent display panels may change depending on their position, and thus the display quality of the display device may deteriorate.

[0101] However, in the case of the display device according to the embodiment, when a first magnet M1 is attached to or disposed on the rear frame CR supporting the display panel DP and a second magnet M2 is attached to or disposed on the second surface S2 of the display panel DP, and when the display panel DP shrinks back to its original size after being stretched due to driving heat, the gap can be restored to the original gap by the attraction between the first magnet M1 and the second magnet M2. In this way, by preventing the gap between the display panels DP from increasing or becoming irregular, the display quality can be prevented from deteriorating due to the increase or irregularity of the gap between the display panels DP.

[0102] Although this disclosure has been described in conjunction with embodiments that are considered to be actual implementations, it will be understood that this disclosure is not limited to the disclosed embodiments, but rather is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
