[0036] The embodiments will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily realize them.

[0037] When a portion of a layer, membrane, region, or plate is referred to as being "on" or "over" another portion, this includes not only being "directly on" but also having another portion therebetween. Conversely, when a component is referred to as being "directly on" another component, this means that there are no other components therebetween.

[0038] Throughout the specification, the expression "a part includes ..." means that the part may further include other elements unless there is an opposite statement that it does not include another element.

[0039] Throughout the specification, "connected" refers not only to a case where two or more components are directly connected, but also to a case where two or more components are indirectly connected, physically connected, or electrically connected through other components. In addition, it may include a case where each part that is referred to by different names according to position or function but is substantially integrated is connected to another part.

[0040] The terms used herein are only used to describe the purpose of specific embodiments and are not intended to be limiting. As used herein, "one", "an", "the" and "at least one" do not represent a limit to quantity and are intended to include both the singular and the plural, unless the context clearly indicates otherwise. For example, "an element" has the same meaning as "at least one element" unless the context clearly indicates otherwise. "At least one" should not be interpreted as being limited to "one" or "one". "Or" means "and / or". As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Throughout this disclosure, the expression "at least one of a, b and c" means only a, only b, only c, both a and b, both a and c, both b and c, all of a, b and c, or variations thereof. It will also be understood that when the terms "comprises" and / or "comprising" or "includes" and / or "comprising" are used in this specification, it specifies the presence of stated features, regions, integers, steps, operations, elements and / or components, but does not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components and / or groups thereof.

[0041] It should be understood that although the terms "first," "second," "third," etc. may be used herein to describe various elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section from another element, component, region, layer, or section. Therefore, without departing from the teachings herein, the "first element," "first component," "first region," "first layer," or "first section" discussed below may be referred to as a second element, second component, second region, second layer, or second region.

[0042] In the accompanying drawings, the symbols "x", "y" and "z" are used to indicate directions, where "x" is used to indicate a first direction, "y" is used to indicate a second direction perpendicular to the first direction, and "z" is used to indicate a third direction perpendicular to the first and second directions.

[0043] Figure 1 is a perspective view of a display device packaging assembly according to an embodiment, and Figure 2 is an exploded perspective view of a display device packaging assembly according to an embodiment.

[0044] refer to Figure 1 and Figure 2 The display device packaging assembly (hereinafter also referred to as “packaging assembly”) 1 may include a packaging tray 10 and a buffer pad 20 .

[0045] The display devices 30 may be loaded in the packaging tray 10 , and the cushioning pad 20 may be placed between the display devices 30 .

[0046] The packaging tray 10 may have a generally rectangular parallelepiped shape as a whole.The packaging tray 10 may have a width in a first direction x, a depth in a second direction y, and a height in a third direction z.

[0047] The packaging tray 10 can be used to load and transport the display device 30. The packaging tray 10 can accommodate the display device 30 and protect the display device 30 from external environment and impact. The packaging tray 10 can be made of a foamed resin such as foamed polystyrene. For example, the packaging tray 10 can be formed by foaming and molding a raw resin in a mold.

[0048] The packaging tray 10 may include expanded polystyrene ("EPS"), expanded polypropylene ("EPP"), expanded polyethylene ("EPE"), etc., but is not limited thereto.

[0049] The packaging tray 10 may include an accommodation space 11 for accommodating the display device 30. The accommodation space 11 may be defined by a wall 12 surrounding the accommodation space 11. The wall 12 may include a first side wall 121 and a second side wall 122 facing each other in a first direction x, and a third side wall 123 and a fourth side wall 124 facing each other in a second direction y.

[0050] The first sidewall 121 may include first, second, and third protrusions 121a, 121b, and 121c protruding toward the accommodation space 11. The second sidewall 122 may include first, second, and third protrusions 122a, 122b, and 122c protruding toward the accommodation space 11. The bottom surface of the accommodation space 11 may be flat.

[0051] The display device 30 can be loaded into the storage space 11 in a lying state (horizontal state). The display device 30 can be loaded so that the screen on which the image is displayed is substantially parallel to the xy plane and substantially perpendicular to the xz plane. A plurality of display devices 30 can be loaded into the packaging tray 10. For example, about 10 or more, about 20 or more, or about 30 or more display devices 30 can be loaded.

[0052] The buffer pad 20 may also be located in the storage space 11 of the packaging tray 10. The buffer pad 20 and the display device 30 may be arranged alternately in the third direction z. That is, the buffer pad 20 may be located between the display devices 30, and the display device 30 may be located between the buffer pads 20. In a structure in which the buffer pads 20 and the display devices 30 are alternately stacked, the buffer pad 20 may be located at the top and the bottom. Therefore, the number of buffer pads 20 may be one more than the number of display devices 30. The buffer pad 20 may have a sticky surface and may prevent movement or sliding between the display devices 30. In addition, the buffer pad 20 may reduce movement or sliding of the display devices 30 within the storage space 11.

[0053] The packaging tray 10 may further include a protection pad 13 provided at the wall 12 .

[0054] In a plan view, the protection pad 13 can be approximately "H" shaped. As used herein, a "plan view" is a view in the direction (third direction z) in which the cushioning pad 20 and the display device 30 are alternately arranged. A portion of the protection pad 13 can be inserted into the wall 12, and a portion of the protection pad 13 can be exposed to the accommodation space 11. For example, in an "H" shaped protection pad 13, the "T" shaped portion can be inserted into the wall 12, and the remaining "I" shaped portion can be exposed to the accommodation space 11. The protection pad 13 can be formed by a plastic material such as polycarbonate and polyethylene terephthalate, and the surface of the portion exposed to the accommodation space 11 can be coated with or attached with a layer made of a cushioning material (e.g., urethane). The protection pad 13 can extend from the top of the accommodation space 11 to the bottom surface. When the display device 30 is loaded into the accommodation space 11 and after the display device 30 is loaded into the accommodation space 11, the edge of the display device 30 can contact the protection pad 13 except the wall 12 and can be supported by the protection pad 13. Therefore, the wall 12 may be prevented from being damaged by being scratched or pressed by the edge of the display device 30 , and movement of the display device 30 in the first direction x and / or the second direction y within the accommodation space 11 may be restricted.

[0055] The packaging tray 10 may further include an auxiliary receiving space 14 located at one side of the receiving space 11. The auxiliary receiving space 14 may receive a printed circuit board assembly ("PBA") (not shown) for driving the display device 30. The number of PCB assemblies may correspond to the number of display devices 30 loaded in the receiving space 11.

[0056] Will refer to Figures 3 to 8 as well as Figure 1 and Figure 2 The display device packaging assembly 1 and the display device 30 loaded therein are described in more detail.

[0057] Figure 3 is a plan view of a display device packaging assembly according to an embodiment, Figure 4 yes Figure 3 A plan view of the display device package assembly shown in FIG, with the uppermost buffer pad removed, and Figure 5 It is along Figure 3 A cross-sectional view taken along line AA' in FIG. Figure 6 is shown with Figure 3 A plan view of a display device with the display device package assembly separated as shown in FIG, and Figure 7 is shown with Figure 3 A plan view of a buffer pad with the display device packaging assembly separated is shown in FIG. Figure 8 yes Figure 3 A partial enlarged view of the display device packaging assembly shown in FIG. Figure 8 Shown Figure 3 FIG. 1 is an enlarged view of the vicinity of the left and right edges of the cushioning pad 20 in FIG.

[0058] like Figures 1 to 8 As shown in , the packaging tray 10 may include a receiving space 11 defined by a wall 12. In the receiving space 11, cushion pads 20 and display devices 30 may be stacked alternately. The cushion pads 20 may be sheets (such as plastic sheets), and the sides of the cushion pads 20 facing each other may be adhesive surfaces. By arranging the cushion pads 20 between the display devices 30, relative movement between the display devices 30 can be prevented or suppressed. In addition, since the cushion pads 20 are provided between the bottom surface of the receiving space 11 and the display device 30 at the bottom, the display device 30 at the bottom can be prevented or suppressed from moving on the bottom surface of the receiving space 11, and all of the display devices 30 whose relative movement is restricted by the cushion pads 20 can be effectively restricted from moving within the receiving space 11.

[0059] The display device 30 may be prevented from moving within the receiving space 11 by the protective pads 13 provided at the first side wall 121, the second side wall 122, and the fourth side wall 124. The display device 30 may include a display panel 310 for displaying an image and a first printed circuit board 330 connected to the display panel 310. Figure 8As shown in , in a plan view, the left and right sides of the display panel 310 can be supported by the protective pads 13 on the left and right sides of the display panel 310. As a result, the display device 30 can be suppressed from moving in the first direction x. The protective pads 13 can be provided only on the lower side of the display device 30 and not on the upper side. This is because, due to the structural characteristics of the display device 30, it may be difficult to install the protective pads 13 that can support the upper side of the display panel 310. Therefore, only the lower side of the display panel 310 is supported by the protective pads 13, which may not be enough to suppress the movement of the display device 30 in the second direction y (i.e., the display device 30 can move upward in a plan view). If the display device 30 moves, the display device 30 may be damaged, and the wall 12 may touch the ground due to the display device 30, and the display device 30 may be contaminated. The buffer pad 20 may have a structure for suppressing the movement of the display device 30 in combination with the wall 12 in the second direction y, which will be described later.

[0060] refer to Figure 6 The display device 30 is described in more detail. The display device 30 includes a display panel 310, a driving unit including a driving integrated circuit chip 320, a first printed circuit board 330, a second printed circuit board 340, etc. At least a portion of the first printed circuit board 330 may be flexible and bendable. The first printed circuit board 330 may be referred to as a flexible printed circuit board or a printed circuit film.

[0061] The display panel 310 may be a light-emitting display panel including light-emitting diodes, or a liquid crystal display panel including a liquid crystal layer, but is not limited thereto. The display panel 310 may have a rectangular plate shape that is thin as a whole, and may provide a screen that displays images. The display panel 310 may have a rectangular shape in a plan view, but may also have various shapes other than a rectangle, such as a polygon or a circle other than a rectangle. The display panel 310 may include a substrate, elements formed on the substrate, and a protective layer covering the elements. The light-emitting display panel may have a circuit layer and light-emitting diodes located between two substrates. The liquid crystal display panel may have a circuit layer and a liquid crystal layer located between two substrates. The substrate may be a rigid substrate including glass. The substrate may be a flexible substrate including plastic such as polyimide. The display panel 310 includes a display area DA corresponding to a screen on which an image is displayed and a non-display area NA arranged with circuits and / or signal lines for generating and / or transmitting various signals applied to the display area DA. The non-display area NA may surround the display area DA. In Figure 6 , the inner side and the outer side of the dotted rectangle may correspond to the display area DA and the non-display area NA, respectively.

[0062] The pixels can be arranged in a matrix in the display area DA of the display panel 310. In addition, signal lines such as gate lines, data lines, and drive voltage lines can be provided in the display area DA. Each pixel can be connected to a gate line, a data line, a drive voltage line, etc., and can receive a gate signal, a data voltage, a drive voltage, etc. from these signal lines. The pixels can be implemented as light-emitting devices such as light-emitting diodes. Touch electrodes for detecting contact and / or contactless touch of a user can be provided in the display area DA. Therefore, the display panel 310 can be a touch screen panel capable of displaying images and detecting touch. Although the display area DA is shown as a roughly rectangular shape, the display area DA can also have various shapes other than a rectangle, such as a polygon, a circle, or an ellipse that is different from a rectangle.

[0063] A driving unit that generates and / or processes various signals for driving the display panel 310 may be located in the non-display area NA of the display panel 310. The driving unit includes a data driver that applies data voltages to the data lines, a gate driver that applies gate signals to the gate lines, and a signal controller that controls the data driver and the gate driver. Pixels may receive data voltages at a certain timing based on the gate signals generated by the gate driver. The gate driver may be integrated into the display panel 310 and may be located on at least one side of the display area DA (e.g., the left and right sides of the display area DA). The data driver may be configured as a driver integrated circuit chip 320. The driver integrated circuit chip 320 may be mounted on the first printed circuit board 330. The driver integrated circuit chip 320 may be mounted in the non-display area NA at the bottom of the display panel 310. Depending on the size of the display panel 310, the data driver may be configured as one or more driver integrated circuit chips 320. In the illustrated embodiment, twelve driver integrated circuit chips 320 are arranged in a row along the first direction x. The signal controller may be provided as an integrated circuit chip, mounted on the second printed circuit board 340 , and electrically connected to the driving integrated circuit chip 320 and the display panel 310 through the first printed circuit board 330 .

[0064] A pad portion (not shown) may be positioned in the non-display area NA of the display panel 310, in which pads are arranged to receive signals from outside the display panel 310. The pad portion may be located at the bottom of the display panel 310. One end of the first printed circuit board 330 may be bonded to the pad portion. The pads of the first printed circuit board 330 may be electrically connected to the pads of the pad portion.

[0065] A signal control unit, a power management integrated circuit (“PMIC”), etc. may be located on the second printed circuit board 340. The other end of the first printed circuit board 330 may be bonded to the second printed circuit board 340.

[0066] In an electronic device to which the display device 30 is applied, once the first printed circuit board 330 is bonded to the pad portion, the first printed circuit board 330 can be bent to wrap around the bottom edge of the display panel 310 approximately parallel to the first direction x. The second printed circuit board 340 can be located on the back side of the display panel 310, minimizing the portion protruding from the display panel 310 and reducing the planar size of the display device 30. However, when the display device 30 is loaded in the packaging tray 10, the first printed circuit board 330 can be unfolded as shown without bending, so that the thickness of the display device 30 is not increased. Since the first printed circuit board 330 is bonded to the vicinity of the upper corner of the display panel 310, it may be difficult to provide a wall 12 with a protective pad 13 that can support and guide the upper side of the display panel 310, and therefore, auxiliary measures may be required to suppress movement of the display device 30 in the second direction y.

[0067] refer to Figure 7 Describing the cushion 20 in more detail, the cushion 20 can be an adhesive sheet having a predetermined thickness. The cushion 20 can have a thickness of, for example, about 1 millimeter (mm) to about 3 mm, and the opposing sides can be adhesive. The cushion 20 can have a structure in which an adhesive layer is laminated on opposing sides of a core layer. The core layer can be a foam sheet or cushioning layer made by non-crosslinked foaming of low-density polyethylene ("LDPE"). The adhesive layers located on the opposing sides of the core layer can be made of high-density polyethylene ("HDPE") and can be bonded to the upper and lower surfaces of the core layer by heat pressing. The materials of the core layer and the adhesive layer can vary. The adhesive layer can be made of a mixture containing high-density polyethylene and an adhesive to provide adhesive strength. Ethylene vinyl acetate ("EVA"), metallocene polyethylene ("m-PE"), etc. can be used as the adhesive. The adhesive layer can also include an antistatic agent to prevent static electricity. Therefore, the cushion 20 can have adhesive properties so that it can be detachably attached to the display device 30.

[0068] The cushion 20 may include a main body 210 and wings 221 to 224. The main body 210 and the wings 221 to 224 may be formed as one body. The main body 210 may correspond to the display panel 310. For example, the main body 210 may be rectangular and may correspond to the display panel 310. Figure 7 The area shown by the dotted line in the middle. In a plan view, the main body 210 may overlap the display panel 310 within the receiving space 11 of the packaging tray 10. The wings 221 to 224 may extend and protrude from the main body 210 in a predetermined direction. Figure 8As shown in FIG, in a plan view, the wings 221 to 224 include a first wing 221 located on the left side of the main body 210, a second wing 222 located on the right side of the main body 210, a third wing 223 located on the upper side of the main body 210, and a fourth wing 224 located on the lower side of the main body 210. The first wing 221 and the second wing 222 may be symmetrical with respect to the main body 210. In a plan view, the first to fourth wings 221 to 224 may not overlap with the display panel 310 (see FIG. Figure 8 and Figure 9 ). In a plan view, the third wing 223 may include a portion overlapping with the first and second printed circuit boards 330 and 340 and a portion not overlapping with the first and second printed circuit boards 330 and 340. In other words, in a plan view, a portion of the third wing 223 close to the body 210 may overlap with the first and second printed circuit boards 330 and 340, and a portion of the third wing 223 far from the body 210 may not overlap with the first and second printed circuit boards 330 and 340.

[0069] refer to Figure 7 and Figure 8 , the first wing 221 may include three sub-wings 221a, 221b and 221c. In a plan view, the first sub-wing 221a may be spaced apart from the upper end of the main body 210, the second sub-wing 221b may be spaced apart from the lower end of the main body 210, and the third sub-wing 221c may be located between the first sub-wing 221a and the second sub-wing 221b. Here, the upper end of the main body 210 may be an end of the third wing 223 in the second direction y, and the lower end of the main body 210 may be an end of the fourth wing 224 opposite to the upper end in the second direction y. The third sub-wing 221c may protrude less from the main body 210 than the first sub-wing 221a and the second sub-wing 221b. In other words, in the first direction x, the width w3 of the third sub-wing 221c can be smaller than the width w1 of the first sub-wing 221a, and the width w3 of the third sub-wing 221c can be smaller than the width w2 of the second sub-wing 221b. For example, the width w1 of the first sub-wing 221a and the width w2 of the second sub-wing 221b can each be about 20 mm or more or about 25 mm or more, and the width w3 of the third sub-wing 221c can be about 10 mm or less or about 5 mm or less. If the width w1 of the first sub-wing 221a and the width w2 of the second sub-wing 221b are less than 20 mm or the width w3 of the third sub-wing 221c is greater than 10 mm, the connection between the first sub-wing 221a, the second sub-wing 221b and the third sub-wing 221c and the first protrusion 121a, the second protrusion 121b and the third protrusion 121c may be weakened, thereby reducing the ability to suppress the movement of the display device 30.

[0070] The width w1 of the first sub-wing 221a and the width w2 of the second sub-wing 221b can be the same, but can also be different from each other. The first wing 221 can be divided into two parts by the third sub-wing 221c. Similar to the first wing 221, the second wing 222 can include three sub-wings 222a, 222b and 222c. The first sub-wing 222a can be spaced apart from the upper end of the main body 210, the second sub-wing 222b can be spaced apart from the lower end of the main body 210, and the third sub-wing 222c can be located between the first sub-wing 222a and the second sub-wing 222b. The third sub-wing 222c can protrude less from the main body 210 than the first sub-wing 222a and the second sub-wing 222b. The second wing 222 can be divided into two parts by the third sub-wing 222c.

[0071] The first sub-wing 221a, the second sub-wing 221b and the third sub-wing 221c of the first wing 221 can be engaged with the first protrusion 121a, the second protrusion 121b and the third protrusion 121c of the first side wall 121. That is, in a plan view, the first sub-wing 221a can be located between the first protrusion 121a and the second protrusion 121b, the second protrusion 121b can be located between the first sub-wing 221a and the second sub-wing 221b and face the third sub-wing 221c, and the second sub-wing 221b can be located between the second protrusion 121b and the third protrusion 121c. In a plan view, the top of the first sub-wing 221a in the second direction y and the bottom of the first protrusion 121a in the second direction y can contact or be adjacent to each other. In a plan view, the upper end of the second sub-wing 221b in the second direction y and the lower end of the second protrusion 121b in the second direction y can contact or be adjacent to each other. In a plan view, the lower end of the first sub-wing portion 221a and the upper end of the second protrusion 121b may contact or be adjacent to each other. Figure 8As shown in , in a plan view, the left end of the third sub-wing 221c and the right end of the second protrusion 121b can be in contact with or adjacent to each other. In the same manner as the relationship between the first wing 221 and the first side wall 121, the first sub-wing 222a, the second sub-wing 222b, and the third sub-wing 222c of the second wing 222 can engage with the first protrusion 122a, the second protrusion 122b, and the third protrusion 122c of the second side wall 122. In this way, by the interlocking structure of the buffer pad 20 and the packaging tray 10 provided by the first wing 221 and the second wing 222 and the first side wall 121 and the second side wall 122, the movement of the buffer pad 20 in the second direction y can be restricted, and the movement of the display device 30 attached to the buffer pad 20 in the second direction y can also be suppressed. Therefore, even if the packaging tray 10 does not include the protection pad 13 supporting the top of the display panel 310 in the second direction y, the display device 30 can be effectively prevented from being pushed, separated, or damaged when an external impact occurs during transportation of the display device packaging assembly 1.

[0072] The second protrusions 121b and 122b and the third sub-wings 221c and 222c can be arranged to align with the central axis X of the display panel 310. Here, alignment can mean that the second protrusions 121b and 122b and the third sub-wings 221c and 222c are located on the central axis X in a plan view. For example, the central axis X can pass through the center of the second protrusions 121b and 122b in the second direction y. The central axis X can correspond to a straight line that evenly divides the display panel 310 vertically (i.e., in the second direction y) and extends in the first direction x. The central axis of the main body 210 can correspond to the central axis X of the display panel 310. That is, the central axis X can divide the main body 210 into two parts, i.e., an upper part and a lower part, equally. In this way, by providing the second protrusions 121b and 122b and the third sub-wings 221c and 222c, the rotation of the display panel 310 can be suppressed.

[0073] As described above, the first wing 221 may include a third sub-wing 221c having a width w3 that is narrower than the width w1 of the first sub-wing 221a and the width w2 of the second sub-wing 221b. In addition, the second wing 222 may include a third sub-wing 222c having a width that is narrower than the width of the first sub-wing 222a and the width of the second sub-wing 222b. When an impact is applied to the display device packaging assembly 1 or the display device packaging assembly 1 is shaken and the display device 30 moves in the first direction x, there is a risk that the display panel 310 may come into contact with the second protrusions 121b and 122b of the side walls 121 and 122. When the display panel 310 comes into contact with the second protrusions 121b and 122b, the second protrusions 121b and 122b may be damaged. This may contaminate the display device 30 or make it difficult to reuse the packaging tray 10. Contact between the display panel 310 and the second protrusions 121b and 122b can be prevented by the third sub-wings 221c and 222c protruding from the main body 210 that overlaps with the display panel 310 in a plan view. Since the third sub-wing 221c is located between the display panel 310 and the second protrusion 121b, the display panel 310 and the second protrusion 121b can be separated by at least the width w3 of the third sub-wing 221c, and also since the third sub-wing 222c is located between the display panel 310 and the second protrusion 122b, the display panel 310 and the second protrusion 122b can be separated by at least the width of the third sub-wing 222c.

[0074] Figure 9 is a partially enlarged plan view of a display device packaging assembly according to another embodiment. Figure 9 Can correspond to Figure 8 The area in the plan view of the display device packaging component 1 is shown in .

[0075] Figure 9The display device packaging assembly 1' shown in FIG differs from the above-described embodiment in the shape of the packaging tray 10. Compared to the above-described embodiment, the third protrusion 121c of the first side wall 121 of the wall 12 can be formed longer in the second direction y, and the third protrusion 121c has two protective pads 13 and 13'. The third protrusion 122c of the second side wall 122, which can be symmetrical with the first side wall 121, can be formed longer in the second direction y, and the third protrusion 122c can also have two protective pads 13 and 13'. When the left and right sides of the display panel 310 are each supported by a single protective pad 13, there is a risk that the display panel 310 may rotate when a large impact is applied to the display device packaging assembly 1. In this embodiment, if the packaging tray 10 is configured to support each side of the display panel 310 with multiple protective pads 13 and 13', and even when a large impact is applied, the display panel 310 can be effectively prevented from moving. To ensure space for deformation of the third protrusion 121c and for providing an additional protective pad 13', the length L2 of the second sub-wing 221b in the second direction y may be shorter than the length L1 of the first sub-wing 221a of the first wing 221. Similarly, the length of the second sub-wing 222b may be shorter than the length of the first sub-wing 222a of the second wing 222. When the second sub-wings 221b and 222b are formed in this manner, if an additional protective pad 13' is required to prevent rotation of the display panel 310, it is sufficient to slightly modify the interior of the mold used to form the packaging tray 10, and deformation of the buffer pad 20 may be unnecessary.

[0076] Figure 10 is a longitudinal cross-sectional view of a display device packaging assembly in an overlapped state according to an embodiment.

[0077] refer to Figure 10 In order to transport multiple display device packaging assemblies at the same time, the display device packaging assemblies can be stacked in the third direction z. That is, the second packaging tray 10b containing the display device 30 and the cushion 20 can be placed on the first packaging tray 10a containing the display device 30 and the cushion 20. The cover 10c can be placed on the second packaging tray 10b instead of another packaging tray. Although Figure 10, but in another embodiment, multiple display device packaging assemblies can be loaded and transported in three or four stages. The bottoms of the packaging trays 10a and 10b may include downwardly protruding protrusions 15a and 15b so that when the packaging assemblies are stacked, the upper packaging assembly (e.g., the second packaging tray 10b) can press the cushioning pad 20 in the receiving space 11 of the lower packaging assembly (e.g., the first packaging tray 10a). The cushioning pad 20 accommodated in the upper packaging tray (e.g., the second packaging tray 10b) can be pressed by the protrusion 15c of the cover 10c. The protrusions 15a, 15b, and 15c can be formed corresponding to the receiving space 11 of the packaging trays 10a and 10b. The protrusions 15a, 15b, and 15c can have a shape that can press the first wing 221 and the second wing 222 and the body 210 of the cushioning pad 20. By the pressing load of the packaging component or cover 10 c located on the upper side, the movement of the cushion pad 20 and the display device 30 attached to the cushion pad 20 can be suppressed.

[0078] Figure 11 is a plan view of a buffer pad in a display device packaging assembly according to another embodiment.

[0079] refer to Figure 11 , the cushion pad 20' may include a main body 210 and wings 221 to 224 formed integrally with the main body 210. The first wing 221 and the second wing 222 may be symmetrical with respect to the main body 210. The first wing 221 and the second wing 222 may be spaced apart from the upper end and the lower end of the main body 210. Unlike the above-mentioned embodiment, the first wing 221 and the second wing 222 are not divided into sub-wings, and each may have a roughly rectangular shape. When the cushion pad 20' is formed in this manner, depending on the shape of the cushion pad 20', the first side wall 121 and the second side wall 122 of the packaging tray 10 may not include the second protrusions 121b and 122b.

[0080] Table 1 below shows the results of the following tests: Figure 7 In the case of the cushion pad 20 shown in FIG. 1 including the first wing 221 including the first sub-wing 221a, the second sub-wing 221b and the third sub-wing 221c and the second wing 222 including the first sub-wing 222a, the second sub-wing 222b and the third sub-wing 222c (embodiment 1) and in the case of using the cushion pad 20 as shown in FIG. Figure 11Computer-aided engineering ("CAE") analysis of the amount of overlapping devices in a display device packaging system using a cushion pad 20' including first wing 221 and second wing 222 (Example 2) is shown. CAE modeling conditions are as follows: display panel size: 31.5 inches, packaging tray expansion ratio: 25x, display device stack count: 24, cushion pad thickness: 1.881 mm, and storage space depth: 108 mm.

[0081] [Table 1]

[0082]

[0083] When using a cushioning pad including an undivided first and second wing (Example 2), the maximum movement of the display panel was reduced to 72% compared to when using a cushioning pad without the first and second wings (Comparative Example). When the first and second wings included first to third sub-wings (Example 1), the maximum movement of the display panel was reduced to 63% compared to the Comparative Example. This shows that when the cushioning pad includes the first and second wings, the movement of the display panel is reduced, and when the first and second wings include sub-wings, the movement of the display panel is further reduced.

[0084] Figure 12 is a plan view of a buffer pad in a display device packaging assembly according to yet another embodiment.

[0085] The cushioning pad 20" may include a main body 210 and wings 221 to 224 integrally formed with the main body 210. The first wing 221 and the second wing 222 may be symmetrical with respect to the main body 210. The first wing 221 may include five sub-wings 221a to 221e. The first sub-wing 221a may be spaced apart from the upper end of the main body 210, the second sub-wing 221b may be spaced apart from the lower end of the main body 210, and the third sub-wing 221c may be located between the first sub-wing 221a and the second sub-wing 221b. The fourth sub-wing 221d may be located between the first sub-wing 221a and the third sub-wing 221c, and the fifth sub-wing 221e may be located between the third sub-wing 221c and the second sub-wing 221b. . The fourth sub-wing 221d and the fifth sub-wing 221e may protrude less from the main body 210 than the first sub-wing 221a, the second sub-wing 221b and the third sub-wing 221c. That is, in the first direction x, the corresponding widths of the fourth sub-wing 221d and the fifth sub-wing 221e may be smaller than the corresponding widths of the first sub-wing 221a, the second sub-wing 221b and the third sub-wing 221c. The first wing 221 may be divided into three parts by the fourth sub-wing 221d and the fifth sub-wing 221e. Similar to the first wing 221, the second wing 222 may include five sub-wings 222a to 222e. The second wing 222 may be divided into three parts by the fourth sub-wing 222d and the fifth sub-wing 222e.

[0086] Although not shown, the first and second side walls 121 and 122 of the packaging tray 10 may include protrusions that may engage with the sub-wings 221 a to 221 e and 222 a to 222 e of the first and second wings 221 and 222 . In this manner, the first wing 221 and the second wing 222 of the cushion 20″ may include a plurality of sub-wings 221a to 221e and 222a to 222e, and the wall 12 of the packaging tray 10 may have a corresponding shape, which can prevent the display device 30 from moving during the transportation process of the display device packaging assembly 1 and from being damaged due to impact. However, compared to an embodiment in which the first wing 221 and the second wing 222 each include three sub-wings 221a to 221c and 222a to 222c, the size of each sub-wing 221a to 221e and 222a to 222e is smaller, which may reduce the structural function of the sub-wings 221a to 221e and 222a to 222e, and during automatic packaging in a facility, the sub-wings 221a to 221e and 222a to 222e may fly apart, causing concern that the sub-wings 221a to 221e and 222a to 222e may fold.

[0087] Although the embodiments have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements are possible by those skilled in the art using the basic concepts defined in the appended claims.
