For example, a first direction may also be referred to as a second direction, and similarly, a second direction may also be referred to as a first direction, without departing from the scope of the embodiments of this application.

[0037] The applicant in this case has provided a solution to the problems existing in the prior art through careful and in-depth research.

[0038] Figure 1 A schematic diagram of a packaging device provided in an embodiment of the present application.

[0039] The embodiment of the present application provides a packaging device 01 for packaging a display panel 02, and can be particularly used for packaging a display panel 02 with side wiring. Figure 1 As shown, the packaging device 01 includes a substrate 10 and a first adhesive film 20. Of course, the first adhesive film 20 is adhesive.

[0040] The substrate 10 is used to support the display panel 02. The area of ​​the substrate 10 is larger than the area of ​​the display panel 02. Here, the area of ​​the substrate 10 and the area of ​​the display panel 02 refer to the orthographic projection area of ​​the substrate 10 and the display panel 02 along the arrangement direction Z of the substrate 10 and the display panel 02 on the plane where the substrate 10 is located.

[0041] The first adhesive film 20 is used to secure the display panel 02. The area of ​​the first adhesive film 20 is larger than that of the display panel 02 and no larger than that of the substrate 10. The area of ​​the first adhesive film 20 refers to the orthographic projection of the first adhesive film 20 onto the plane of the substrate 10 along the arrangement direction Z of the substrate 10 and the display panel 02.

[0042] It should be noted that Figure 1 The case where the area of ​​the first adhesive film 20 is smaller than the area of ​​the substrate 10 is merely illustrated.

[0043] The first mucous film 20 includes a first part 21 and a second part 22 . The first part 21 is connected to the second part 22 . The first part 21 is located on the side of the display panel 02 away from the substrate 10 . The first part 21 covers the display panel 02 , and the second part 22 is bonded to the substrate 10 .

[0044] When packaging the display panel 02 using the packaging device 01, the display panel 02 can be placed on the substrate 10, and then the first adhesive film 20 is covered on the side of the display panel 02 away from the substrate 10, and the first adhesive film 20 is bonded to the substrate 10, thereby fixing the display panel 02 on the substrate 10. The surface of the substrate 10 to be bonded to the second portion 22 can be a smooth surface, and the side of the first adhesive film 20 facing the substrate 10 can be adhesive, while the side facing away from the substrate can be non-adhesive.

[0045] In the embodiment of the present application, a substrate 10 with a larger area is used to support the display panel 02, and a first adhesive film 20 is provided to fix the display panel 02 on the substrate 10. This can improve the stability of the display panel 02, and is beneficial to reducing the probability of the display panel 02 being damaged by bumps during transportation. In particular, it is beneficial to reduce the probability of the display panel 02 with side wiring being damaged due to bumps on the side wiring, thereby avoiding unnecessary yield loss of the display panel 02 due to transportation.

[0046] Moreover, the packaging device provided in the embodiment of the present application can be batch-produced and reused, and the operation process is simple and convenient, which is conducive to the standardized management of the display panel 02 packaging process, and can improve the packaging efficiency of the display panel 02, which is conducive to saving manpower and reducing costs.

[0047] Optionally, the substrate 10 includes at least one of rigid polyvinyl chloride, polystyrene, polyethylene terephthalate, and polymethyl methacrylate. In this way, the substrate 10 can have a high bending modulus, is not prone to bending deformation, and can provide stable support for the display panel 02.

[0048] Furthermore, the viscosity of the first adhesive film 20 is Z1, 5gf / inch≤Z1≤15gf / inch. This helps ensure that the first adhesive film 20 can firmly fix the display panel 02 on the substrate 10, and also reduces the difficulty of peeling the first adhesive film 20 and the display panel 02, making it easier to remove the display panel 02 from the packaging device 01.

[0049] Alternatively, the first adhesive film 20 may include at least one of polyimide and polyethylene terephthalate.

[0050] In one embodiment of the present application, the adhesion between the second portion 22 of the first adhesive film 20 and the substrate 10 is greater than the adhesion between the first portion 21 of the first adhesive film 20 and the display panel 02 .

[0051] It can be understood that the greater the adhesion between the second portion 22 and the substrate 10 , the greater the reliability of the adhesion between the second portion 22 and the substrate 10 .

[0052] In the embodiment of the present application, the viscosity between the second part 22 and the substrate 10 is set to be relatively large. During the transportation of the display panel 02, it can be further ensured that the display panel 02 is stably fixed in the space enclosed by the first adhesive film 20 and the substrate 10, thereby helping to reduce the probability of the display panel 02 being damaged by bumps during transportation, and further helping to reduce the yield loss of the display panel 02 caused by transportation.

[0053] At the same time, the adhesion between the first portion 21 and the display panel 02 is set to be relatively small, so when the display panel 02 is taken out of the packaging device 01, the first adhesive film 20 can be peeled off from the display panel 02 more conveniently, which helps to avoid damage to the display panel 02.

[0054] Figure 2 A top view of a packaging device provided in an embodiment of the present application.

[0055] Please continue to refer to Figure 1 In one embodiment of the present application, the first adhesive film 20 includes at least two second portions 22 , and the at least two second portions 22 are located on different sides of the display panel 02 .

[0056] Optionally, when the first adhesive film 20 includes only two second portions 22 , the two second portions 22 are located on opposite sides of the display panel 02 .

[0057] Furthermore, the number of the second parts 22 included in the first adhesive film 20 can match the shape of the display panel 02 .

[0058] For example Figure 2 As shown, the display panel 02 includes four side edges, and the first adhesive film 20 includes four second portions 22 . The four second portions 22 are respectively located at the four side edges of the display panel 02 .

[0059] In the embodiment of the present application, providing the first adhesive film 20 with at least two second parts 22 can further increase the stability of the display panel 02, which is beneficial for further preventing the display panel 02 from being damaged during transportation.

[0060] Figure 3 This is a schematic diagram of another packaging device provided in an embodiment of the present application.

[0061] In one embodiment of the present application, Figure 3 As shown, the packaging device 01 further includes a second adhesive film 30, which is located between the display panel 02 and the substrate 10. The material of the second adhesive film 30 can be the same as that of the first adhesive film 20.

[0062] Optionally, the second adhesive film 30 is attached to the surface of the display panel 02 facing the substrate 10 .

[0063] In the embodiment of the present application, a second adhesive film 30 is provided between the display panel 02 and the substrate 10. On the one hand, the second adhesive film 30 can protect the display panel 02 to prevent the surface of the display panel 02 from being scratched when the display panel 02 is transported or placed; on the other hand, the van der Waals force between the display panel 02 and the substrate 10 can be reduced to prevent the display panel 02 from being too tightly attached to the substrate 10 and being difficult to remove when the display panel 02 is taken out of the packaging device 01.

[0064] Optionally, the second adhesive film 30 is a single-sided adhesive film, that is, one side of the second adhesive film 30 is adhesive and the other side is non-adhesive, and the adhesive side of the second adhesive film 30 is adhered to the display panel 02. In this way, during the transportation of the display panel 02, if the display panel 02 slides slightly, the second adhesive film 30 can slide with the display panel 02 to prevent the display panel 02 from being scratched.

[0065] In one embodiment of the present application, the adhesion between the second adhesive film 30 and the display panel 02 is smaller than the adhesion between the second portion 22 of the first adhesive film 20 and the substrate 10 .

[0066] Optionally, the adhesion between the second adhesive film 30 and the display panel 02 is substantially the same as the adhesion between the first portion 21 of the first adhesive film 20 and the display panel 02 .

[0067] Of course, in some other embodiments, the adhesion between the second adhesive film 30 and the display panel 02 and the adhesion between the first portion 21 of the first adhesive film 20 and the display panel 02 may also be different.

[0068] In the embodiment of the present application, the adhesion between the second adhesive film 30 and the display panel 02 is set to be relatively small. Therefore, when the display panel 02 is taken out of the packaging device 01, the second adhesive film 30 can be peeled off from the display panel 02 more conveniently, which helps to avoid damage to the display panel 02.

[0069] Figure 4 This is a schematic diagram of another packaging device provided in an embodiment of the present application. Figure 5 for Figure 4 A top view of the middle substrate. Figure 6 for Figure 4 Another top view of the mid-base plate.

[0070] Combine Figure 4 and Figure 5 ,or Figure 4 and Figure 6As shown, in one embodiment of the present application, the substrate 10 includes a groove structure 11. The groove structure 11 is located on the side of the substrate 10 that supports the display panel 02. The groove structure 11 overlaps the display panel 02 along the arrangement direction Z of the substrate 10 and the display panel 02. Of course, the arrangement direction of the substrate 10 and the display panel 02 can be the same as the thickness direction of the substrate 10 and the thickness direction of the display panel 02.

[0071] Alternatively, as Figure 5 As shown, the substrate 10 includes a plurality of groove structures 11 . The groove structures 11 extend along a first direction X, and the plurality of groove structures 11 are arranged along a second direction Y. The first direction X and the second direction Y intersect.

[0072] Alternatively, as Figure 6 As shown, the substrate 10 includes a plurality of groove structures 11 , some of which extend along a first direction X, and some extend along a second direction Y, where the first direction X intersects the second direction Y. That is, the substrate 10 includes groove structures 11 that intersect each other.

[0073] In the embodiment of the present application, a groove structure 11 is provided on the side of the display panel 02 facing the substrate 10, so that the van der Waals force between the display panel 02 and the substrate 10 can be reduced, which helps to prevent the display panel 02 from being too tightly attached to the substrate 10 and difficult to remove when the display panel 02 is taken out of the packaging device 01.

[0074] Furthermore, along the arrangement direction Z of the substrate 10 and the display panel 02, the same groove structure 11 also includes a portion that does not overlap with the display panel 02. This allows air to enter the groove structure 11, which helps prevent vacuum adsorption between the display panel 02 and the substrate 10, thereby further preventing the display panel 02 from being too tightly attached to the substrate 10 when removing the display panel 02 from the packaging device 01, making it difficult to remove.

[0075] In one embodiment of this application, please continue to refer to Figure 4 Along the arrangement direction Z of the substrate 10 and the display panel 02 , the display panel 02 overlaps with at least two different groove structures 11 .

[0076] The at least two different groove structures 11 may not intersect with each other, may cross with each other, or may partially cross and partially not cross.

[0077] In the embodiment of the present application, the display panel 02 is arranged to overlap with at least two different groove structures 11, so that the overlapping area of ​​the display panel 02 and the groove structure 11 can be larger, and it is beneficial to make different areas of the display panel 02 overlap with the groove structure 11, thereby helping to further reduce the difficulty of removing the display panel 02 from the substrate 10.

[0078] Figure 7 A schematic diagram of a substrate provided in an embodiment of the present application.

[0079] Combine Figure 1 and Figure 7 As shown, in one embodiment of the present application, the surface of the substrate 10 facing the display panel 02 includes a first area 10A and a second area 10B. Along the arrangement direction Z of the substrate 10 and the display panel 02, the first area 10A overlaps with the display panel 02, and the second area 10B does not overlap with the display panel 02. The roughness of the first area 10A is greater than that of the second area 10B.

[0080] That is, the portion of the supporting surface of the substrate 10 corresponding to the display panel 02 may be a non-smooth, rough surface.

[0081] It can be understood that the surface of the display panel 02 is usually a smooth surface, and the adsorption force between the smooth surface and the rough surface with greater roughness is usually relatively small.

[0082] In the embodiment of the present application, the portion of the supporting surface of the substrate 10 corresponding to the display panel 02 is set to a non-smooth rough surface, which can reduce the adsorption force between the substrate 10 and the display panel 02, thereby reducing the difficulty of removing the display panel 02 from the substrate 10.

[0083] Figure 8 A top view of another packaging device provided in an embodiment of the present application.

[0084] like Figure 8 As shown, in one embodiment of the present application, a guide line 23 is provided on the first adhesive film 20. When the first adhesive film 20 fixes the display panel 02 on the substrate 10, the guide line 23 is located at the edge of the first adhesive film 20 covering the display panel 02. The second portion 22 of the first adhesive film 20 can be bonded to the substrate 10 along the guide line 23.

[0085] Optionally, the guide line 23 is in the form of a groove to guide the second portion 22 of the first adhesive film 20 to adhere to the substrate 10 .

[0086] Alternatively, as Figure 8 As shown, the guide line 23 is a ring structure. Further, the shape of the guide line 23 can be adapted to the outer shape of the display panel 02.

[0087] For example, for a display panel 02 having a rectangular outer shape, the guide line 23 may also be in a rectangular shape.

[0088] In the embodiment of the present application, the provision of the guide line 23 can make the first adhesive film 20 easier to bend, which is conducive to bonding the second portion 22 of the first adhesive film 20 to the substrate 10 more tightly, thereby improving the fixing effect on the display panel 02.

[0089] Figure 9 A top view of another packaging device provided in an embodiment of the present application, Figure 10 A top view of another packaging device provided in an embodiment of the present application, Figure 11 A top view of another packaging device provided in an embodiment of the present application.

[0090] In one embodiment of the present application, the first adhesive film 20 is provided in a one-to-one correspondence with the display panel 02, and a substrate 10 can support at least one display panel 02. That is, at least one display panel 02 can be provided on a substrate 10, and each display panel 02 is secured using a first adhesive film 20. It is understood that when a substrate 10 supports multiple display panels 02, the total area of ​​the multiple display panels 02 is smaller than the area of ​​the substrate 10.

[0091] The first mucosa 20 has a shape of a square, a cross, or a regular hexagon.

[0092] For example, Figure 8 As shown, the shape of the first mucosa 20 can be a cross. Alternatively, as shown Figure 9 As shown, the shape of the first mucous membrane 20 is a square. Of course, the shape of the first mucous membrane 20 can be a rectangle or a square. Figure 10 As shown, the shape of the first mucosa 20 can also be a regular hexagon.

[0093] In the embodiment of this application, Figure 11 As shown, when a substrate 10 carries multiple display panels 02 , the shape design of the first adhesive film 20 is conducive to improving the layout rate of the display panels 02 , thereby facilitating fixing a larger number of display panels 02 on the substrate 10 .

[0094] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
