Description

Technical Field

[0001] This utility model relates to a tray. Background Technology

[0002] The importance of display devices is increasing along with the development of multimedia. Such display devices include liquid crystal displays (LCDs) and organic light-emitting displays (OLEDs).

[0003] Liquid crystal display devices include liquid crystal display panels that use the light transmittance of liquid crystals to display images, and organic light-emitting display devices include organic light-emitting display panels.

[0004] Liquid crystal display panels may include a polarizing plate on top of them, while organic light-emitting display panels may include an anti-reflective film on top of them. Such polarizing plates or anti-reflective films can be bonded to the underlying substrate with an adhesive material; however, in this case, the display panel may be easily peeled off or damaged due to external impacts during storage or transportation.

[0005] To prevent damage to the display panels, they can be stored and transported in a tray with storage space. The tray can be used to store or transport multiple display panels stacked together.

[0006] On the other hand, the tray is made of foamed plastic materials such as expanded polystyrene (EPS) and expanded polypropylene (EPP). However, trays made of such foamed plastic materials have relatively low impact resistance. Therefore, multiple slots can be arranged inside the tray to correspond to the corner portions of the display panel. The slots minimize the flow of the display panel within the tray, thus preventing damage to the display panel due to external impacts. Utility Model Content

[0007] The purpose of this invention is to provide a tray that prevents the polarizing plate or anti-reflective film from separating from the display panel during the transfer of the display panel.

[0008] The subject matter of this utility model is not limited to the subject matter mentioned above, and another technical subject matter not mentioned will be clearly understood by those skilled in the art from the following description.

[0009] A tray according to an embodiment of the present invention for achieving the above-mentioned purpose includes: a body comprising: a base; a receiving portion formed on the upper side of the base and accommodating a display panel; a sidewall surrounding the receiving portion on the upper side of the base; and one or more grooves disposed on the inner surface of the sidewall facing the receiving portion, the grooves protruding from the inner surface of the sidewall toward the receiving portion, the protruding length of the upper end of the groove being longer than the protruding length of the lower end of the groove.

[0010] Alternatively, the protruding length of the groove may gradually decrease from the upper end to the lower end of the groove.

[0011] Alternatively, the groove may extend from the upper end to the lower end of the sidewall.

[0012] The sidewall may have a first side extending in a first direction, a second side extending in a second direction intersecting the first direction, a third side facing the first side, and a fourth side facing the second side, with the groove disposed on one or more of the inner surfaces of the first side, the second side, the third side, and the fourth side.

[0013] Alternatively, the groove may be disposed on the inner surface of the first side and the inner surface of the second side in a first region where the first side and the second side intersect, on the inner surface of the second side and the inner surface of the third side in a second region where the second side and the third side intersect, on the inner surface of the third side and the inner surface of the fourth side in a third region where the third side and the fourth side intersect, and on the inner surface of the first side and the inner surface of the fourth side in a fourth region where the first side and the fourth side intersect.

[0014] The display panel may have a long side and a short side, and the distance between the upper end of the slot on the first side and the upper end of the slot on the third side is longer than the length of the long side of the display panel.

[0015] It is possible that the distance between the upper end of the slot portion disposed on the second side and the upper end of the slot portion disposed on the fourth side is longer than the length of the short side of the display panel.

[0016] It is possible that the groove portion disposed on the first side and the third side protrudes in the second direction, and the groove portion disposed on the second side and the fourth side protrudes in the first direction.

[0017] Alternatively, the tray may further include a cushioning component disposed on the underside of the display panel.

[0018] Alternatively, the display panels may be provided in multiple forms and stacked inside the receiving portion, and the buffer components may be provided in multiple forms and disposed between the multiple display panels.

[0019] Specific details of other embodiments are included in the detailed description and accompanying drawings.

[0020] According to the tray of this utility model, by forming the groove to gradually narrow from the top to the bottom of the main body, it has the effect of minimizing the external impact applied to the display panel when the display panel is moved, thereby preventing the polarizing plate or anti-reflective film from separating from the display panel.

[0021] On the other hand, the effects that can be obtained in this invention are not limited to those mentioned above, and another effect not mentioned will be clearly understood by those skilled in the art to which this invention pertains from the following description.

[0050] The various features of the various embodiments of this utility model can be combined or integrated with each other, either partially or entirely, and can be linked and driven in various ways. Alternatively, each embodiment can be implemented independently of the others, or they can be implemented together in an associated relationship.

[0051] The following description refers to the accompanying drawings and provides specific embodiments.

[0052] Figure 1 This is a perspective view of a tray according to an embodiment of the present invention. Figure 2 yes Figure 1 Floor plan.

[0053] In the accompanying drawings, the first direction D1 and the second direction D2 may intersect each other in the horizontal direction. For example, the first direction D1 and the second direction D2 may be orthogonal to each other. Additionally, the third direction D3 may be a direction that is perpendicular to and orthogonal to both the first direction D1 and the second direction D2.

[0054] Reference Figure 1 as well as Figure 2 According to one embodiment of the present invention, the tray 10 can be used as a display panel DP (refer to...). Figure 8 It accommodates the display panel (DP) for purposes such as transportation and storage.

[0055] In one embodiment, the display panel DP can be any one of a liquid crystal display panel, an electrophoretic display panel, a MEMS display panel (microelectromechanical system display panel), an electrowetting display panel, an organic light emitting display panel, a micro LED display panel, a quantum dot display panel, and a quantum rod display panel, without particular limitation.

[0056] The display panel (DP) may include a lower substrate, an upper substrate, optical components, and sealing components. The lower substrate may include switching elements such as TFTs (Thin-Film Transistors) and other components for driving them. The upper substrate may include other components for color reproduction of the display panel (DP), such as a color conversion layer and a color filter layer. When the display panel (DP) is a liquid crystal display panel, the optical component may be a polarizing plate; when the display panel (DP) is an organic light-emitting diode (OLED) display panel, the optical component may be an anti-reflective film.

[0057] In addition, the display panel DP may also include a window unit, a driving unit, protective components, a backlight unit, and a chassis, as needed. The window unit may include window glass and a window base layer. The driving unit may include a driving circuit board or other circuit board used to drive the display panel DP. Protective components may include a protective film, a heat dissipation layer, a metal plate, etc. When the display panel DP is a liquid crystal display panel, a backlight unit may also be included below the display panel DP. The backlight unit may include a light source and a light guide plate.

[0058] When viewed on a flat surface, the display panel DP can be formed into a roughly rectangular shape. In other words, the display panel DP can have a short side extending in one direction and a long side extending in a direction orthogonal to the other direction.

[0059] The shape of the display panel DP is not particularly limited. This embodiment exemplarily shows a flat display panel, but in another embodiment, the display panel DP can be a curved display panel.

[0060] The tray 10 may include a body 100 and one or more slots 200.

[0061] The main body 100 can accommodate the display panel DP. The main body 100 may include a base 110, a receiving portion 120, and a sidewall 130.

[0062] The substrate 110 can support the display panel DP. The substrate 110 can be provided as a plate with a predetermined thickness, and the planar shape of the substrate 110 can follow the planar shape of the display panel DP.

[0063] The receiving portion 120 may be formed on the upper side of the substrate 110. The receiving portion 120 may be formed on the upper side of the substrate 110 via a sidewall 130 disposed on the upper side of the substrate 110. The receiving portion 120 may be formed in an open-top configuration to receive a display panel DP that is moved in through the open top. The planar shape of the receiving portion 120 may be slightly larger than the planar shape of the display panel DP.

[0064] The sidewall 130 may be configured along the outer periphery of the base 110. The sidewall 130 may extend from the upper outer periphery of the base 110 in a third direction D3. In other words, the sidewall 130 may be configured to surround the receiving portion 120 formed on the upper side of the base 110. The sidewall 130 may be dimensioned in the plane defining the receiving portion 120 on the upper side of the base 110.

[0065] The outer surface of the sidewall 130 can be rectangular in shape in a plane. In other words, the sidewall 130 can have a rectangular planar form, having a short side extending in a first direction D1 and a long side extending in a second direction D2. For example, the sidewall 130 may include a first side 131 extending in the first direction D1, a second side 132 extending in the second direction D2, a third side 133 facing the first side 131, and a fourth side 134 facing the second side 132. Alternatively, the third side 133 may face the first side 131, thus extending in the first direction D1, and the fourth side 134 may face the second side 132, thus extending in the second direction D2. The first side 131 and the third side 133 may be short sides, and the second side 132 and the fourth side 134 may be long sides.

[0066] It is possible that the first side 131 is connected to the second side 132 in the first region C, the second side 132 is connected to the third side 133 in the second region D, the third side 133 is connected to the fourth side 134 in the third region E, and the fourth side 134 is connected to the first side 131 in the fourth region F.

[0067] The main body 100 constructed as described above may be formed by comprising expanded polystyrene (EPS), expanded polypropylene (EPP), or a mixture thereof. The main body 100 of foam plastic materials such as expanded polystyrene (EPS) and expanded polypropylene (EPP) may have relatively low impact resistance.

[0068] The groove 200 is disposed on the inner surface of the sidewall 130 facing the receiving portion 120 to prevent damage to the display panel DP due to external impact. The groove 200 can be formed of a different material than the sidewall 130. As an example, the groove 200 can also be manufactured by pressurizing a resin having a foaming rate different from that of the main body 100, or it can be formed of a rubber material. Multiple grooves 200 can be provided.

[0069] Multiple slots 200 can be disposed on the inner surface of the sidewall 130 so as to be disposed inside the receiving portion 120 of the main body 100. Multiple slots 200 can be disposed in the corner regions C, D, E, and F of the main body 100. For example, the slots 200 can be disposed in the first region C where the first side 131 and the second side 132 intersect, on the inner surfaces of the first side 131 and the second side 132; in the second region D where the second side 132 and the third side 133 intersect, on the inner surfaces of the second side 132 and the third side 133; in the third region E where the third side 133 and the fourth side 134 intersect, on the inner surfaces of the third side 133 and the fourth side 134; and in the fourth region F where the first side 131 and the fourth side 134 intersect, on the inner surfaces of the first side 131 and the fourth side 134. In other words, two grooves 200 can be disposed in each of the corner regions C, D, E, and F of the main body 100, and can be configured to directly contact the inner surface of the sidewall 130. In this embodiment, it is described that two grooves 200 are disposed in each of the corner regions C, D, E, and F of the main body 100, but the number and placement of the grooves 200 are not particularly limited. The grooves 200 can also be disposed only on the inner surface of a portion of the sidewall 130.

[0070] Figure 3 It is along Figure 1 A cross-sectional view taken from the A-A' line. Figure 4 It is magnification Figure 3 An enlarged view of part G. Figure 5 It is along Figure 1 A cross-sectional view taken from the B-B' line. Figure 6 It is magnification Figure 5 An enlarged view of part H.

[0071] Further reference Figures 3 to 6 The groove 200 can be accessed from the side wall 130 (refer to...) Figure 1 The inner surface of the groove 200 protrudes towards the receiving portion 120. In other words, the groove 200 can protrude from the inner surface of the sidewall 130 in either the first direction D1 or the second direction D2. For example, the groove 200 disposed on the first side 131 and the third side 133 may protrude in the second direction D2, while the groove 200 disposed on the second side 132 and the fourth side 134 may protrude in the first direction D1.

[0072] The groove 200 can extend from the upper end to the lower end of the sidewall 130. In other words, the groove 200 can extend from the upper end of the inner surface of the sidewall 130 to the lower end of the inner surface of the sidewall 130.

[0073] A protruding surface 210 may be formed at the protruding end of the groove 200. The protruding surface 210 may be formed to be parallel to the side of the display panel DP housed in the receiving portion 120. In other words, the protruding surface 210 may be arranged parallel to the short side or the long side of the display panel DP. When the display panel DP is housed in the receiving portion 120, the protruding surface 210 may be parallel to the side of the display panel DP (see reference 120). Figure 8 The protruding surface 210 is separated from the short or long side of the display panel DP.

[0074] The protruding surface 210 may be formed obliquely outward from the upper end to the lower end of the sidewall 130. For example, the protruding surface 210 of the groove 200 disposed on the first side 131 and the third side 133 may be formed obliquely in the second direction D2 from the upper end to the lower end of the sidewall 130. Specifically, the protruding surface 210 of the groove 200 disposed on the first side 131 may be formed obliquely in the second direction D2. Figure 5 It is formed at a downward angle on the right side, and the protruding surface 210 of the groove 200 located on the third side 133 is positioned in the second direction D2. Figure 5 It is formed by tilting downwards to the left.

[0075] Furthermore, the protruding surfaces 210 of the grooves 200 disposed on the second side 132 and the fourth side 134 can be formed obliquely in the first direction D1 as they extend from the upper end to the lower end of the sidewall 130. Specifically, the protruding surfaces 210 of the grooves 200 disposed on the second side 132 can be formed obliquely in the first direction D1. Figure 3 It is formed at a downward angle on the left side, and the protruding surface 210 of the groove 200 located on the fourth side 134 faces the first direction D1. Figure 3 It is formed by tilting downwards to the right.

[0076] The protruding length of the groove 200, which protrudes from the inner surface of the side wall 130 toward the receiving portion 120, can gradually decrease from the upper end to the lower end of the groove 200. Therefore, the protruding length L1 at the upper end of the groove 200 can be longer than the protruding length L2 at the lower end of the groove 200.

[0077] Figure 7 It is shown in Figure 2 A floor plan containing the state of the display panel. Figure 8 It is shown in Figure 3 A cross-sectional view showing the state of the display panel. Figure 9 It is shown in Figure 5 A cross-sectional view showing the state of the display panel.

[0078] Further reference Figures 7 to 9When viewed in a plane, the display panel DP may have a short side SS extending in a first direction D1 and a long side LS extending in a second direction D2. If the display panel DP is moved into the receiving portion 120 for reception, the space between the slots 200 needs to be formed larger than the planar dimension of the display panel DP.

[0079] In detail, the distance between the upper ends of the slot 200 disposed on the first side 131 and the upper ends of the slot 200 disposed on the third side 133 can be longer than the length of the long side LS of the display panel DP. Furthermore, the distance between the upper ends of the slot 200 disposed on the second side 132 and the upper ends of the slot 200 disposed on the fourth side 134 can be longer than the length of the short side SS of the display panel DP. Thus, with the distance between the upper ends of the slot 200 disposed on the first side 131 and the upper ends of the slot 200 disposed on the third side 133 being longer than the length of the long side LS of the display panel DP, and the distance between the upper ends of the slot 200 disposed on the second side 132 and the upper ends of the slot 200 disposed on the fourth side 134 being longer than the length of the short side SS of the display panel DP, the display panel DP can be inserted into the receiving portion 120 of the main body 100 to accommodate the main body without being disturbed by the slot 200.

[0080] Multiple display panels (DPs) can be provided and stacked within the receiving portion 120. A buffer member 300 can be disposed between the stacked display panels (DPs) within the receiving portion 120. The buffer member 300 prevents damage to the top and bottom of the display panels (DPs) from impacts from outside the tray 10. The buffer member 300 can be formed to a size smaller than the planar dimensions of the display panels (DPs). For example, the buffer member 300 may have a short side and a long side, with the short side of the buffer member 300 having a length smaller than the short side SS of the display panel (DP), and the long side of the buffer member 300 having a length smaller than the long side LS of the display panel (DP). The center of the buffer member 300 can be configured to overlap with the center of the display panels (DPs).

[0081] The function and effect of the tray 10 according to an embodiment of the present invention will be described below.

[0082] When the spacing between the slots 200 is formed to correspond to the length of the short side SS or long side LS of the display panel DP, when the display panel DP is accommodated in the receiving portion 120, the short side SS and long side LS of the display panel DP may come into contact with the protruding surface 210 of the slot 200. In this case, if an impact is applied to the tray 10 during the transfer of the tray 10, the short side SS or long side LS of the display panel DP may move upward or downward in the slot 200 while in contact with the slot 200 due to the impact. During this process, the polarizing plate or anti-reflective film of the display panel DP may separate from the display panel DP. If the polarizing plate or anti-reflective film separates from the display panel DP, it may cause a defect in the display panel DP.

[0083] However, in the case of the tray 10 according to an embodiment of the present invention, the short side SS and long side LS of the display panel DP do not contact the groove 200, so even if an impact from outside the tray 10 is transmitted to the display panel DP, the polarizing plate or anti-reflective film can be prevented from separating from the display panel DP.

[0084] Furthermore, the protruding surface 210 of the groove 200 is formed at an angle towards the outside of the main body 100 as it moves from the upper end to the lower end of the groove 200. Therefore, when the display panel DP moves upward due to an impact from outside the tray 10, the protruding surface 210 presses down on the short side SS and long side LS of the display panel DP. Thus, in the tray 10 according to an embodiment of the present invention, even if the display panel DP moves upward while being contained in the tray 10, the groove 200 presses down on the short side SS and long side LS of the display panel DP, thereby preventing the polarizing plate or anti-reflective film from separating from the display panel DP.

[0085] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, those skilled in the art to which this invention pertains will understand that it can be implemented in other specific forms without altering the technical concept or essential features of the present invention. Therefore, the embodiments described above should be understood as exemplary in all respects and not limiting.
