[0041] To make the objectives, technical solutions, and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0042] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the ordinary meanings understood by those of ordinary skill in the art to which the present application belongs. The "first", "second" and similar terms used in the embodiments of the present application do not denote any order, quantity or importance, but are only used to distinguish different components. The terms such as "including" or "comprising" mean that the elements or objects appearing before this term cover the elements or objects listed after this term and their equivalents, without excluding other elements or objects. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left", "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0043] In the related art, a tray structure as shown in Figure 1 is adopted to package the ultra-thin glass-based display products and flexible display products 30. This tray structure cannot limit the relative sliding of the ultra-thin glass-based display products and flexible display products in the horizontal direction (such as Figure 1 the x-direction and y-direction in ). Therefore, during transportation, for example, when the tray shakes due to external forces, the ultra-thin glass-based display products and flexible display products will slide relatively in the tray, which may cause scratches, or deformation or even breakage, etc., resulting in risks such as product defects.

[0044] Based on this, an embodiment of the present application provides a packaging structure, in which a supporting film 10 is adhesively fixed to a display product 30 (such as an ultra-thin glass-based display product and a flexible display product) and a supporting frame 20 (such as a supporting ring) respectively through a first adhesive layer (such as the back adhesive of the supporting film), so as to limit the display product 30 (such as an ultra-thin glass-based display product and a flexible display product) in three directions (such as the x direction, the y direction, and the z direction) in space; the four sides of the protective film 50 are attached to the supporting film 10, which strengthens the limitation of the display product 30 in three directions (such as the x direction, the y direction, and the z direction) in space. Then, the supporting frame 20 (such as a supporting ring) with the display product is inserted vertically into the box body 70, so as to limit the supporting frame 20 (such as a supporting ring) in three directions (such as the x direction, the y direction, and the z direction) in space, and further limit the display product 30 (such as an ultra-thin glass-based display product and a flexible display product) in three directions (such as the x direction, the y direction, and the z direction) in space. In this way, the suspended packaging of the product is realized through two limiting methods, which can solve to a certain extent the problems that the display product 30 (such as an ultra-thin glass-based display product and a flexible display product) cannot be limited during transportation, resulting in relative sliding, scratches, deformation, or even damage, and reduce the risk of product defects.

[0045] Please refer to Figure 2 and Figure 3 , an embodiment of the present application provides a packaging structure, which may include:

[0046] A supporting film 10; the supporting film 10 is used to support the display product 30;

[0047] A first adhesive layer 40, provided on the supporting film 10;

[0048] A supporting frame 20, bonded to the first adhesive layer 40, so that the supporting film 10 spreads along the plane defined by the supporting frame 20;

[0049] Wherein, the supporting film 10 surrounded by the supporting frame 20 includes a display product area; the first adhesive layer 40 located in the display product area is used to bond the display product 30. The orthographic projection of the first adhesive layer on the supporting film 10 and the orthographic projection of the display product area on the supporting film 10 at least partially overlap, and the orthographic projection of the first adhesive layer 40 on the supporting film 10 and the orthographic projection of the supporting frame 20 on the supporting film 10 at least partially overlap.

[0050] The packaging structure of the embodiment of the present application includes a supporting film 10; the supporting film 10 is used to support the display product 30; a first adhesive layer 40 is provided on the supporting film 10; a supporting frame 20 is bonded on the first adhesive layer; wherein, the supporting film surrounded by the supporting frame 20 includes a display product area; the first adhesive layer 40 located in the display product area is used to bond the display product; the orthographic projection of the supporting frame 20 on the supporting film 10 does not overlap with the orthographic projection of the display product area on the supporting film 10; the orthographic projection of the first adhesive layer 40 on the supporting film 10 at least partially overlaps with the orthographic projection of the supporting frame 20 on the supporting film 10; such a technical solution can buffer and limit the display product 30 in multiple directions (such as the x direction, y direction, and z direction) during transportation, avoid the relative sliding between the display product 30 and the supporting film 10, and further avoid scratches, deformation, and damage caused by relative sliding.

[0051] In some embodiments, the supporting film 10 can be a supporting film made of plastic material, etc. The material of the supporting film 10 can be at least one of polyethylene terephthalate (PET), polyethylene (PE), high-density polyethylene (HDPE), polypropylene (PP), or polyvinyl chloride (PVC), etc. The supporting film 10 is used to support the display product 30, and the thickness of the supporting film 10 can be adjusted accordingly according to specific requirements.

[0052] In some embodiments, the first adhesive layer 40 can be a single-sided back adhesive of the supporting film 10. Generally, the supporting film 10 can be provided with a back adhesive film for bonding the supporting frame 20 and the display product 30.

[0053] In some embodiments, as Figure 4 shown, the first adhesive layer 40 can include a first bonding area 41 (such as a first back adhesive area) and a second bonding area 42 (such as a second back adhesive area) which are arranged at intervals (such as discontinuously). The first bonding area can be used to bond the display product. The second bonding area can be used to bond the supporting frame. Among them, the materials of the first bonding area and the second bonding area are different, so that the first bonding area and the second bonding area have different viscosities.

[0054] Here, the orthographic projection of the display product area on the supporting film 10 at least partially overlaps with the orthographic projection of the first bonding area on the supporting film 10, for example, it can partially overlap or completely overlap, etc., to bond the display product 30 on the supporting film 10. The orthographic projection of the supporting frame 20 on the supporting film 10 at least partially overlaps with the orthographic projection of the second bonding area on the supporting film 10, for example, it can partially overlap or completely overlap, etc., to bond the supporting film 10 on the supporting frame 20.

[0055] Generally, the first bonding area 41 can be adjusted with specific materials according to the material and weight of the display product 30, etc. The second bonding area 42 can be adjusted with specific materials according to the material and weight of the supporting frame 20, etc. It should be understood that the requirement for the viscosity of the material for metal materials, etc. is greater than that for plastic materials, etc. Thus, when the supporting frame 20 is made of a metal material, the viscosity of the material in the first bonding area 41 is greater than that in the second bonding area 42.

[0056] In some embodiments, the supporting frame 20 can be a supporting ring, which generally has good supporting strength and is in a ring structure. The material of the supporting frame 20 can be steel, aluminum alloy, rigid plastic, or a combination of steel and plastic, etc., and the thickness can be greater than or equal to 2.5 mm. For example, the supporting frame 20 can be a flange ring, etc.

[0057] In some embodiments, the supporting frame can be selected from a complete rectangular ring or a rectangular ring with a unilateral notch. That is, the supporting frame can be a supporting frame with a complete ring shape, or a rectangular ring with a notch.

[0058] In some embodiments, returning to Figure 2 , the distance (such as d2) between the supporting frame 20 and the display product area can be greater than or equal to 25 mm. In this way, it can avoid the contact between the display product 30 and the supporting frame 20, and avoid the supporting frame 20 exerting a force on the display product 30. It should be noted that the size of the display product 30 can be equal to the size of the display product area, or smaller than the size of the display product area, and the present disclosure does not limit this.

[0059] In some embodiments, the display product 30 can be an ultra-thin glass-based display product 30 or a flexible display product 30. Generally, the thickness of the display product 30 is relatively small, for example, it can be about 0.09 mm.

[0060] In some embodiments, continuing to refer to Figure 2 and Figure 3 , the packaging structure can further include a protective film 50. The protective film 50 can be disposed on the side of the display product 30 away from the supporting film 10. By providing the protective film 50, it can play a certain protective role for the display product 30, for example, it can prevent dust and avoid dirt, etc.

[0061] In some of these embodiments, the packaging structure may further include a second adhesive layer 60 disposed on the protective film 50 for bonding the protective film 50 to the display product. Exemplarily, the second adhesive layer 60 may be a single-sided full-surface back adhesive of the protective film 50. That is, the second adhesive layer 60 is disposed on the side of the protective film 50 close to the display product 30, and the size of the second adhesive layer 60 may be adapted to the size of the protective film 50. Generally, the orthographic projection of the protective film 50 on the supporting film 10 and the orthographic projection of the display product 30 on the supporting film 10 at least partially overlap. That is, the protective film 50 at least partially covers the display product area.

[0062] In some of these embodiments, continuing to refer to Figure 2 , at least a part of the protective film 50 is attached to the supporting film 10 (such as the supporting film 10 body or the first adhesive layer 40 disposed on the supporting film) to form a first accommodating cavity 52 between the protective film 50 and the supporting film 10 (such as the supporting film body or the first adhesive layer 40 disposed on the supporting film), and the display product 30 is disposed in the first accommodating cavity 52. For example, all edges of the protective film 50 may be attached to the supporting film 10, or only some edges may be attached to the supporting film 10. That is, in the plane where x and y are located, at least a part of the protective film extends outside the display product area. The second adhesive layer is also used to bond the protective film 50 to the supporting film 10 or to bond the protective film 50 to the first adhesive layer 40. In this way, the limiting effect on the display product 30 can be better achieved.

[0063] In some of these embodiments, the orthographic projection of the protective film 50 on the supporting film 10 may completely cover the orthographic projection of the display product 30 on the supporting film 10. The size of the protective film 50 may be larger than the size of the display product 30, and the excess part may be pasted to the supporting film 10 to further limit the display product 30 in three directions of space (such as the x direction, the y direction, and the z direction). For example, in the second direction (such as the x direction) and in the first direction (such as the y direction), the size of the protective film 50 may be larger than the size of the display product 30 by at least 10 mm.

[0064] In some of these embodiments, such as Figure 5a , Figure 5b , Figure 5c , Figure 5d , Figure 5e and Figure 5fAs shown, the shape of the protective film 50 may include a circle, a near circle, an ellipse, a triangle, a parallelogram, a rectangle, a rhombus, etc. It should be understood that the shape of the protective film 50 is generally adapted to the shape of the display product 30. For example, for a rectangular display product 30, the shape of the protective film 50 is generally rectangular, and for a circular display product 30, the shape of the protective film 50 is generally circular. Among them, when the shape of the protective film 50 is a triangle, a rectangle, a rhombus, etc., at least one vertex angle (such as one vertex angle, multiple vertex angles, and all vertex angles, etc.) of the protective film 50 is provided with a cut groove 51 to reduce the force on the corner of the display product 30, thereby avoiding damage to the corner of the product due to force.

[0065] In some embodiments, the material of the protective film 50 may be PET, PP, etc.

[0066] In some embodiments, as shown in Figure 6 As shown, the packaging structure of the embodiment of the present application may further include a box body 70. The box body 70 is provided with at least one accommodation cavity (such as a second accommodation cavity 71). For example, one accommodation cavity, two accommodation cavities, or more accommodation cavities may be provided, which can be determined according to the packaging requirements of the specific display product 30, etc. The accommodation cavity (such as the second accommodation cavity 71) can be used to accommodate the supporting film 10 and the supporting frame 20 packaging the display product 30.

[0067] In some embodiments, at least one limiting groove may be provided in the accommodation cavity (such as the second accommodation cavity 71). For example, limiting grooves may be provided on the side wall and the bottom of the box body. The supporting frame 20 can be inserted into the limiting groove.

[0068] In some embodiments, the limiting groove may be a continuous integral structure limiting groove, such as a limiting groove provided along the bottom surface and two side walls of the box body 70; or it may be a discontinuous first limiting groove and a second limiting groove, such as a first limiting groove and a second limiting groove respectively provided on two opposite side walls of the box body 70.

[0069] In this way, the supporting frame 20 can be limited by the box body 70, thereby strengthening the further limitation of the display product 30 in three directions (such as the x direction, the y direction, and the z direction) in space.

[0070] In some embodiments, the depth of the limiting groove may be greater than or equal to 15 mm. In this way, the limiting dimension of the box body 70 for the supporting frame 20 can be greater than or equal to 15 mm.

[0071] In some embodiments, as shown in Figure 6As shown, the limiting groove extends at least partially in the height direction of the box body. That is, the limiting groove may extend in the z' direction. Here, the height direction of the box body refers to the direction perpendicular to the horizontal plane when the box body is normally placed on the horizontal plane.

[0072] At this time, after the supporting frame 20 is inserted into the limiting groove, since the height direction is perpendicular to the horizontal plane, it is shown that the display product 30 is also perpendicular to the horizontal plane. Therefore, risks such as bending of the display product 30 due to its own weight can be avoided. Moreover, the adjacent display products 30 will not be stacked, and there is no need to place spacer materials between the display products 30.

[0073] In some embodiments, the material of the box body 70 may be expandable polystyrene foam (EPS), expandable polystyrene-polyethylene mixed foam (EPO), or expandable polypropylene foam (EPP). These materials are all common foam materials, which have good buffering performance while ensuring the support strength, and can better protect the display product 30.

[0074] In some embodiments, referring back to Figure 3 As shown, at least one slot 21 is formed in the supporting frame 20. By forming the slot 21, it is convenient to identify the insertion direction of the supporting frame 20 into the box body (such as the feeding direction). For example, the end where the slot is located can be inserted into the box body, or the opposite end can be inserted into the box body.

[0075] In some embodiments, the slot 21 may be provided with two, which is convenient for device limiting and identifying the feeding direction. Among them, the shapes of the two slots 21 can be different to play an anti-misoperation role.

[0076] In some embodiments, continue to refer to Figure 2 , the width of the supporting frame 20 (such as d1) may be greater than the depth of the limiting groove. In this way, contact between the display product 30 and the box body 70 can be avoided, which is beneficial to realizing the suspended packaging of the product.

[0077] Based on the same inventive concept, corresponding to the packaging structure of any of the above embodiments, the present application also provides a packaging method. Specifically, the packaging method includes:

[0078] Providing a supporting film 10 provided with a first adhesive layer 40;

[0079] Bonding the supporting frame 20 on the first adhesive layer 40 so that the supporting film 10 spreads along the plane defined by the supporting frame 20; wherein, the supporting film 10 surrounded by the supporting frame 20 includes a display product area;

[0080] Bonding the display product on the first adhesive layer 40 in the display product area;

[0081] Provide a box body 70 including a limiting groove;

[0082] After bonding the display product, insert the supporting frame 20 into the limiting groove. At least part of the edge of the supporting frame 20 is clamped in the limiting groove.

[0083] Wherein, the orthographic projection of the supporting frame 20 on the supporting film 10 does not overlap with the orthographic projection of the display product area on the supporting film 10; the orthographic projection of the first adhesive layer on the supporting film 10 overlaps at least partially with the orthographic projection of the display product area on the supporting film 10, and the orthographic projection of the first adhesive layer on the supporting film 10 overlaps at least partially with the orthographic projection of the supporting frame 20 on the supporting film 10.

[0084] In some embodiments, before inserting the supporting frame 20 into the limiting groove, the packaging method may further include: bonding a protective film 50 on the side of the display product 30 away from the supporting film 10.

[0085] Exemplarily, the protective film 50 is provided with a second adhesive layer 60, and the protective film 50 is bonded to the display product 30 through the second adhesive layer 60. The protective film 50 at least partially covers the display product area.

[0086] In some embodiments, at least part of the protective film 50 extends to the outside of the display product area; the protective film 50 is bonded to the supporting film 10 or the first adhesive layer 40 through the second adhesive layer 60.
