Detailed Implementation

[0044] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0045] With the continuous advancement of technology, users' demands for screen-to-body ratio in electronic devices are increasing. Currently, the edges of electronic device screen modules need to maintain a certain safe distance from the mid-frame to prevent damage to the screen module edges from collisions, pressure, etc.

[0046] For example, such as Figure 1 As shown, screen module 1 uses a flexible display screen. Taking advantage of the flexible and bendable properties of the display screen, the portion near the lower edge is bent backwards to form a bending area 112, thereby reducing the bezel width. Screen module 1 is typically bonded to the middle frame 2 via a cover plate 13, thus fixing screen module 1 to the middle frame 2. At this time, the bezel width L consists of three parts: the first part (as shown in the image)... Figure 1 A) shown in the figure represents the width of at least a portion of the bending area 112 of the screen module 1, and the second portion (as shown in the figure) represents the width of the bending area 112 of the screen module 1. Figure 1 As shown in section B), a certain safety distance is provided for the bending area 112, i.e., the width of the clearance. This clearance can prevent the bending area 112 from being damaged by impact, squeezing, collision, etc. during assembly, thereby affecting the reliability of the screen module 1. (The third part...) Figure 1 C) shown in the diagram represents the fixed width for connecting and fixing the screen module 1 to the mid-frame 2. It can be understood that the bezel width refers to the distance from the edge of the display area of ​​the screen to the mid-frame of the electronic device.

[0047] To address the aforementioned technical issues, this disclosure provides a screen module with a protective structure extending along at least one side of the display panel. By covering the edge area of ​​the display panel on that side, the protective structure effectively prevents damage to the edge area of ​​the display panel caused by impacts, compression, etc., thereby improving the reliability of the display panel. Simultaneously, it eliminates the need for a safety distance from the edge area of ​​the display panel, allowing for a reduction in the bezel width on the side where the protective structure is located, thus increasing the screen-to-body ratio of the electronic device.

[0048] An exemplary embodiment of this disclosure provides a screen module, such as Figure 5As shown, the screen module 1 includes a display panel 11 and a protective structure 12. The protective structure 12 extends along at least one side of the display panel 11. For example, the display panel 11 is rectangular and has four sides. The protective structure 12 can be disposed on one of the sides and extend along the length direction of that side, or it can be disposed on all four sides, with the protective structure 12 on each side extending along the length direction of its corresponding side. The protective structure 12 covers the edge area of ​​the display panel 11 on its respective side to prevent damage to the edge area of ​​the display panel 11 caused by impact, compression, etc., thereby effectively improving the reliability of the display panel 11. It is understood that "the protective structure 12 covers the edge area of ​​the display panel 11 on its respective side" means that the protective structure 12 wraps around the edge area of ​​the display panel 11 and covers the surface of the edge area.

[0049] In this embodiment, by setting a protective structure 12 to protect the edge area of ​​the display panel 11, there is no need to set a safety distance for the edge area of ​​the display panel 11. The bezel width can be reduced on the side where the protective structure is set, thereby increasing the screen ratio of the electronic device.

[0050] In one embodiment, such as Figure 2 As shown, the display panel 11 includes a body 111, and a bending area 112 is provided on at least one side of the body 111. Exemplarily, the display panel 11 is a flexible display panel with bendable properties. The bending area 112 is provided on at least one side of the body 111. For example, the bending area 112 can be provided on one side of the body 111, or it can be provided on each side of the body 111. By providing the bending area 112, the bezel width on the side where the bending area 112 is located can be further reduced, thereby increasing the screen-to-body ratio of the electronic device.

[0051] like Figure 5 As shown, the protective structure 12 at least covers the bending area 112. Exemplarily, the protective structure 12 only covers the bending area 112, or it can cover at least a portion of the body 111 near the bending area 112 while covering the bending area 112. With this design, the bending area 112 is protected without the need for a clearance gap, thereby further reducing the bezel width on the side where the bending area 112 is located and increasing the screen-to-body ratio of the electronic device.

[0052] In one embodiment, the width of the bending area 112 is smaller than the width of the body 111, for example, as shown in the example. Figure 14 As shown, the display panel 11 includes a body 111 and a fan-out area 113 connected to the body 111. The fan-out area 113 is used to bend to form a bending area 112. The width L1 of the fan-out area 113 is smaller than the width L2 of the body 111, that is, the width of the bending area 112 is smaller than the width of the body 111. Figure 5As shown, the protective structure 12 extends from the bending area 112 to both sides to cover the edge areas of the body 111 located on both sides of the bending area 112. Exemplarily, a bending area 112 is provided on one side of the body 111, the bending area 112 being located in the middle region of that side. Along the length of that side, the protective structure 12 extends from the bending area 112 to both sides of the body 111, thereby covering the edge areas of the body 111 located on both sides of the bending area 112. This design improves the comprehensiveness of protection for the side where the protective structure 12 is located, further enhancing the reliability of the screen module 1.

[0053] Continue to refer to Figure 5 In one embodiment, the thickness of the protective structure 12 in the bending area 112 is greater than the thickness of the protective structure 12 in the body 111. This arrangement improves the protection effect on the bending area 112 while reducing the amount of material used in the protective structure 12. This not only reduces production costs but also facilitates the thinner and lighter design of electronic devices.

[0054] Continue to refer to Figure 5 In one embodiment, the display panel includes a first surface 114 and a second surface 115 facing each other. The body 111 of the display panel 11 includes a first side edge, and a bending region 112 is connected to the first side edge. The protective structure 12 includes a first protective part 121 and a second protective part 122 connected together. The first protective part 121 covers the edge region of the first surface 114 on the side where the first side edge is located, and the second protective part 122 covers the first surface located in the bending region 112. This design enables protection of the edge region on the side where the bending region 112 is located, thereby improving the reliability of the screen module 1.

[0055] Continue to refer to Figure 5 In one embodiment, the display panel 11 further includes an extension area 116 connected to the bending area 112. The extension area 116 is used to connect to, for example, a motherboard of an electronic device, thereby controlling the display of the display panel 11. The protective structure 12 further includes a filling portion 123 and a third protective portion 124. The third protective portion 124 is connected to the second protective portion 122 and covers at least a portion of the first surface 114 located in the extension area 116. The filling portion 123 fills the space formed by the second surface 115 of a portion of the body 111, the bending area 112, and a portion of the extension area 116. This design effectively improves the comprehensiveness of protection for the bending area 112 and the edge area on the side where the bending area 112 is located, and can further improve the reliability of the screen module 1. For example, the first protective part 121, the second protective part 122, the third protective part 124 and the filling part 123 are integrally formed structures. For example, liquid glue can be injected, and the liquid glue can be cured to form an integral protective structure 12. This arrangement facilitates the processing and manufacturing of the protective structure 12.

[0056] In one embodiment, such as Figure 8 As shown, the main body 111 also includes a second side, and the protective structure 12 includes a fourth protective part 125, a fifth protective part 126, and a first connecting part 127 connecting the fourth protective part 125 and the fifth protective part 126. The fourth protective part 125 covers the edge area of ​​the first surface 114 on the side where the second side is located, and the fifth protective part 126 covers the edge area of ​​the second surface 115 on the side where the second side is located. At this time, the first connecting part 127 covers the side surface between the first surface 114 and the second surface 115. This design achieves protection for the edge areas of the other sides of the display panel 11 that do not have the bending area 112, thereby improving the comprehensiveness and effectiveness of the protection for the edge areas of the display panel 11, and further enhancing the reliability of the screen module 1.

[0057] In one embodiment, such as Figure 2 As shown, the screen module 1 also includes a cover plate 13, which can be, for example, a glass cover plate. The cover plate 13 protects the display panel 11. The display panel 11 is located on the back of the cover plate 13. Along the thickness direction of the electronic device, the projection of the display panel 11 onto the cover plate 13 is within the cover plate 13; that is, the projection of the display panel 11 onto the cover plate 13 is a frontal projection. This improves the protective effect of the cover plate 13 on the display panel 11. Furthermore, the edge of the cover plate 13 has a preset distance from the edge of the display panel 11. This preset distance can be used to connect with the mid-frame 2 of the electronic device, facilitating the fixation of the screen module 1. Figure 5 As shown, the protective structure 12 covers the edge area of ​​the screen module 1 while contacting the back of the cover plate 13. This arrangement can fix the protective structure 12, preventing it from shifting or falling off, thereby effectively improving the reliability of the screen module 1.

[0058] In one embodiment, such as Figure 5As shown, the protective structure 12 can be a gel-like structure formed by curing adhesive, such as UV (Ultraviolet Rays) adhesive, epoxy resin adhesive, or PUR (Polyurethane Reactive) adhesive. Exemplarily, this can be achieved by injecting adhesive into the edge region of the screen module 1, which then cures to form the gel-like structure. Alternatively, an accommodating space can be provided in the edge region of the gel-like structure corresponding to the screen module 1, and the edge region of the screen module 1 can be embedded within this accommodating space. This design, on the one hand, facilitates the processing and manufacturing of the protective structure 12, reducing processing costs; on the other hand, the gel-like structure has a certain degree of elasticity, which can improve the protective effect and prevent the protective structure 12 itself from damaging the screen module 1. Simultaneously, the gel-like structure is lightweight, thus contributing to the lightweight design of electronic devices. In another embodiment, the protective structure 12 can also be a polymer material component, such as rubber or adhesives. The protective structure 12 can also be a foamed structure.

[0059] In one embodiment, such as Figure 9 As shown, the back of the display panel 11 partially covered by the protective structure 12 has a stepped structure 14. Exemplarily, the display panel 11 includes a multi-layer structure, such as a touch layer and a display layer, with varying area sizes between each layer, resulting in a stepped structure 14 forming at the edge of adjacent layers. The stepped structure 14 includes at least two stepped surfaces, arranged along the extension direction of the side edge on the side where the stepped structure 14 is located on the display panel 11. Gaps exist between adjacent layers. When the protective structure 12 is formed by injection molding, adhesive can easily enter the screen module 1 through these gaps, affecting not only the cleanliness of the screen module 1 but also its normal operation. It is understood that the extension direction of the side edge refers to the length direction of that side edge.

[0060] Based on this, such as Figure 12 As shown, in this embodiment, the screen module 1 further includes a blocking structure 15, which covers the stepped structure 14 in its extending direction. This design, on the one hand, seals the gaps created at the stepped structure 14 by the blocking structure 15, preventing adhesive from entering the screen module 1 through these gaps, thereby effectively improving the reliability of the screen module 1. On the other hand, since the blocking structure 15 is located on the back of the display panel 11, it also provides some protection to the back of the screen module 1, preventing damage caused by pressure or impact.

[0061] For example, the blocking structure 15 may also be a rubber block.

[0062] An exemplary embodiment of this disclosure provides an electronic device, which may be a mobile device such as a mobile phone, tablet computer, laptop computer, handheld computer, in-vehicle electronic device, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), or a non-mobile device such as a personal computer (PC), television (TV), ATM, or self-service machine.

[0063] like Figure 5 As shown, the electronic device includes a mid-frame 2 and a screen module 1 as described above, with the screen module 1 fixed to the mid-frame 2. The screen module 1 includes a display panel 11 and a protective structure 12. The protective structure 12 extends along at least one side of the display panel 11, covering the edge area of ​​the display panel 11 on that side to prevent damage to the edge area of ​​the display panel 11 caused by impacts, compression, etc., thereby effectively improving the reliability of the display panel 11. By providing the protective structure 12 to protect the edge area of ​​the display panel 11, there is no need to set a safety distance for the edge area of ​​the display panel 11, and the width of the bezel 22 can be reduced on the side where the protective structure 12 is located, thereby increasing the screen-to-body ratio of the electronic device.

[0064] In one embodiment, such as Figure 6 As shown, the middle frame 2 includes a middle frame body 21 and a frame 22 surrounding the edge of the middle frame body 21. The frame 22 and the middle frame body 21 together define an accommodating cavity. The screen module 1 is fixed to the middle frame 2, and the display panel 11 of the screen module 1 is located within the accommodating cavity. A second connecting portion 221 protrudes from the inner side of the frame 22. The second connecting portion 221 is positioned opposite to the back edge area of ​​the cover plate 13 of the screen module 1. When the screen module 1 is assembled onto the middle frame 2, the back edge area of ​​the cover plate 13 rests on the second connecting portion 221. On one hand, the second connecting portion 221 provides support for the screen module 1, preventing impact between the back of the screen module 1 and the middle frame body 21, thus preventing damage to the screen module 1. On the other hand, the second connecting portion 221 facilitates the connection and fixation between the screen module 1 and the middle frame 2, allowing the back edge area of ​​the cover plate 13 to be bonded to the second connecting portion 221 with adhesive, thereby improving the assembly convenience and efficiency of the electronic device.

[0065] In another embodiment, such as Figure 7As shown, the middle frame 2 includes a middle frame body 21 and a frame 22 surrounding the edge of the middle frame body 21. Each frame 22 and the middle frame body 21 together form an accommodating cavity. The screen module 1 is fixed to the middle frame 2, and the display panel 11 of the screen module 1 is located within the accommodating cavity. The protective structure 12, on its side facing away from the cover plate 13, is bonded to the middle frame body 21, thereby fixing the screen module 1 to the middle frame 2. This design eliminates the need for a second connecting portion 221 protruding from the inner side of the frame 22 for fixing the screen module 1, thus further reducing the distance between the edge of the display area of ​​the display panel 11 and its corresponding frame 22, thereby further improving the screen-to-body ratio of the electronic device. Furthermore, in this embodiment, as... Figure 7 As shown, the inner side of the border 22 can be a flat surface or a smooth curved surface, which can further reduce the width of the border.

[0066] An exemplary embodiment of this disclosure provides a mold (such as...) Figure 3 The first mold 3 shown is used to form the protective structure 12 on the screen module 1. For ease of description, this mold will be referred to as the first mold 3 in the following text. Figure 3 The first mold 3 includes a first mating part 31 for abutting against the edge of the cover plate 13 of the screen module 1, a second mating part 32 for abutting against the back of the display panel 11 of the screen module 1, and a third connecting part 33 connecting the first mating part 31 and the second mating part 32. The first mold 3 is used to cooperate with the screen module 1 to form a first cavity 34 for accommodating at least a portion of the side of the display panel 11. Exemplarily, the first mating part 31 is a frame structure adapted to the cover plate 13, so that the cover plate 13 is embedded in the frame structure, the edge of the cover plate 13 abuts against the inner side of the frame structure, and each edge of the frame extends away from the cover plate 13 to exceed the height of the display panel 11. It can be understood that the height of the display panel 11 is also the thickness of the display panel 11. One end of the second mating part 32 abuts against the back of the display panel 11, and the other end of the second mating part 32 is connected to the first mating part 31 through the third connecting part 33. Thus, the first mating part 31, the third connecting part 33, and the second mating part 32 together enclose and form a first mold cavity 34, which forms a sealed cavity with the screen module 1. At least one side of the display panel 11 has a bending area 112 and at least a portion of its body 111 located within the first mold cavity 34. Exemplarily, the first mold 3 may provide the second mating part 32 and the third connecting part 33 corresponding to one side of the display panel 11, thereby forming the first mold cavity 34 on that side. Alternatively, the first mold 3 may form the first mold cavity 34 corresponding to each side of the display panel 11.

[0067] The first mold 3 is provided with a pouring port 35 communicating with the first mold cavity 34, through which glue (such as...) is poured into the first mold cavity 34. Figure 4The first glue 36 shown fills the first mold cavity 34 with glue, as shown. Figure 5 As shown, a protective structure 12 is formed after the adhesive cures. In this embodiment, the number of injection ports 35 can be one, and one injection port 35 can be located on the first mating part 31, the second mating part 32 or the third connecting part 33. The number of injection ports 35 can also be multiple, for example, injection ports 35 are provided on the first mating part 31, the second mating part 32 and the third connecting part 33.

[0068] In this embodiment, the side of the screen module 1 where the protective structure 12 needs to be installed is first sealed using the first mold 3, and then glue is poured in to form the protective structure 12. This design effectively prevents glue from flowing into the interior of the screen module 1 or even the electronic device, thereby improving the reliability of the electronic device. On the other hand, the method of forming the protective structure 12 as described above is simple and easy to operate, effectively solving the problem that it is difficult to install the protective structure 12 due to the complex structure of the edge area of ​​the screen module 1, thus effectively improving the efficiency and convenience of processing the protective structure 12.

[0069] In one embodiment, such as Figure 3 As shown, when the back of the display panel 1 of the screen module 1 has a stepped structure 14, the screen module 1 also has a blocking structure 15, which covers the stepped structure 14 in the extending direction. Based on this, a portion of the second mating part 32 is provided with a mating groove, which is used to mate with the blocking structure 15 of the screen module 1. For example, when the first mold 3 is assembled into the screen module 1, the blocking structure 15 is embedded in the mating groove. This arrangement improves the sealing performance when the second mating part 32 is connected to the back of the screen module 1, preventing glue leakage. Furthermore, pressing the second mating part 32 against the blocking structure 15 also protects the back of the screen module 1, preventing damage caused by direct pressure from the second mating part 32 against the screen module 1, thereby improving the reliability of the screen module 1.

[0070] In one embodiment, the first mold 3 is made of an elastic material, such as silicone. This facilitates assembly with the screen module 1 while effectively preventing damage to the screen module 1 caused by the first mold 3, thus ensuring the reliability of the screen module 1.

[0071] An exemplary embodiment of this disclosure provides a mold (such as...) Figure 10 The second mold 4 shown is used to form the blocking structure 15 on the screen module 1. For ease of description, this mold will be referred to as the second mold 4 in the following text. Figure 9As shown, the back of the display panel 11 of the screen module 1 has a stepped structure 14. Along the extension direction of the side edge on the side where the stepped structure 14 is located on the display panel 11, the stepped structure 14 has an uneven structure. The stepped structure 14 has a first stepped surface 141 located at one end of the extension direction and a second stepped surface 142 located at the other end of the extension direction.

[0072] like Figure 10 and Figure 13 As shown, the second mold 4 includes a third mating part 41 for abutting against the first step surface 141, a fourth mating part 42 for abutting against the second step surface 142, and a fourth connecting part 43 connecting the third mating part 41 and the fourth mating part 42. The second mold 4 is used to cooperate with the step structure 14 to form a second mold cavity. Exemplarily, the third mating part 41 is a frame structure that can be fitted onto the screen module 1. One end of the fourth mating part 42 can abut against the second step surface 142, and the other end of the fourth mating part 42 is connected to the third mating part 41 through the fourth connecting part 43. The side of the fourth connecting part 43 facing the screen module 1 is adapted to the uneven structure, so that the third mating part 41, the fourth connecting part 43, and the fourth mating part 42 can be used to enclose and form the second mold cavity, which can cover the step structure 14 in the extending direction.

[0073] First, pour glue (such as...) into the second mold 4. Figure 11 The second adhesive 44 is used to assemble the second mold 4 onto the screen module 1 before the adhesive is fully cured, so that the adhesive in the second mold cavity covers the stepped structure 14, and the adhesive in the second mold cavity forms a shape that matches the stepped structure 14. Figure 12 As shown, a barrier structure 15 is formed after the glue has fully cured.

[0074] Compared to directly injecting glue into the step structure 14 to form a blocking structure 15, this arrangement effectively prevents glue from entering the screen module 1 through the gaps in the step structure 14, thereby improving the reliability of the screen module 1.

[0075] By setting the blocking structure 15 to seal the gaps generated at the step structure 14, the adhesive used to form the protective structure 12 is prevented from entering the screen module 1 through the gaps, thereby effectively improving the reliability of the screen module 1. At the same time, the blocking structure 15 is located on the back of the display panel 11, and the blocking structure 15 can also protect the back of the screen module 1 to a certain extent, preventing damage to the back of the screen module 1 caused by squeezing or impact.

[0076] An exemplary embodiment of this disclosure provides a screen module processing method, such as... Figure 15 As shown, the screen module processing method includes the following steps:

[0077] S100. The first mold is fitted with the initial screen module to form a first mold cavity, the first mold cavity accommodating at least a portion of the side of the display panel of the initial screen module.

[0078] In this step, such as Figure 3 As shown, the first mold 3 includes a first mating part 31 for abutting against the edge of the cover plate 13 of the screen module 1, a second mating part 32 for abutting against the back of the display panel 11 of the screen module 1, and a third connecting part 33 connecting the first mating part 31 and the second mating part 32. The first mold 3 is used to cooperate with the initial screen module to form a first mold cavity 34 for accommodating at least part of the side of the display panel 11.

[0079] Exemplarily, the first mating part 31 is a frame structure adapted to the cover plate 13, so that the cover plate 13 is embedded in the frame structure, the edge of the cover plate 13 abuts against the inner side of the frame structure, and each edge of the frame structure extends away from the cover plate 13 to exceed the height of the display panel 11. It can be understood that the height of the display panel 11 is also the thickness of the display panel 11. One end of the second mating part 32 abuts against the back of the display panel 11, and the other end of the second mating part 32 is connected to the first mating part 31 through the third connecting part 33. Thus, the first mating part 31, the third connecting part 33 and the second mating part 32 can be together to form a first mold cavity 34, and the first mold cavity 34 forms a sealed cavity with the initial screen module. The bending area 112 of at least one side of the display panel 11 and at least a portion of the body 111 are located in the first mold cavity 34. Exemplarily, the first mold 3 can be provided with the second mating part 32 and the third connecting part 33 corresponding to one side of the display panel 11, thereby forming the first mold cavity 34 on that side. The first mold 3 can also form a first mold cavity 34 corresponding to each side of the display panel 11.

[0080] S200, Inject the first glue into the first mold cavity.

[0081] In this step, such as Figure 4 As shown, a pouring port 35 is provided on the first mold 3. The first glue 36 is poured into the first mold cavity 34 through the pouring port 35. For example, the number of pouring ports 35 can be one, and the pouring port 35 can be located on the first mating part 31, the second mating part 32 or the third connecting part 33. The number of pouring ports 35 can also be multiple. For example, pouring ports 35 are provided on the first mating part 31, the second mating part 32 and the third connecting part 33.

[0082] S300, the first adhesive cures to form a protective structure.

[0083] In this step, such as Figure 5 As shown, after the first adhesive 36 cures, a protective structure 12 is formed.

[0084] S400, Remove the first mold to obtain the screen module.

[0085] In this step, after the first adhesive 36 has cured, the first mold 3 is removed to obtain the screen module 1, so as to facilitate subsequent assembly.

[0086] In this embodiment, the side of the initial screen module where the protective structure 12 needs to be set is first sealed using the first mold 3, and then glue is poured in to form the protective structure 12. This design effectively prevents the first glue 36 from flowing into the interior of the initial screen module or even the electronic device, thereby improving the reliability of the electronic device. On the other hand, the screen module processing method in this embodiment is simple and easy to operate in processing the protective structure 12, effectively solving the problem that it is difficult to set the protective structure 12 due to the complex structure of the edge area of ​​the screen module 1, thereby effectively improving the efficiency and convenience of processing the protective structure 12.

[0087] Furthermore, by setting up a protective structure 12 to protect the edge area of ​​the display panel 11, there is no need to set a safety distance for the edge area of ​​the display panel 11, which can further reduce the width of the bezel 22, thereby further improving the screen ratio of the electronic device.

[0088] In one embodiment, the process of fitting the first mold with the initial screen module specifically includes the following steps:

[0089] The first mating part of the first mold abuts against the edge of the cover plate of the screen module, and the second mating part of the first mold abuts against the back of the display panel of the screen module.

[0090] In this embodiment, the first mating part 31 of the first mold 3 abuts against the cover plate 13 of the screen module 1, and the second mating part 32 of the first mold 3 abuts against the back of the display panel 11. This improves the sealing performance between the first mold 3 and the screen module 1, preventing the first adhesive 36 from leaking out from the gap between the first mold 3 and the screen module 1, thereby enhancing the reliability of the electronic device.

[0091] In one embodiment, such as Figure 9 As shown, the back of the display panel 11 has a stepped structure 14, which includes at least two stepped surfaces. The at least two stepped surfaces are arranged along the extension direction of the side of the side on which the stepped structure 14 is located on the display panel 11.

[0092] Before assembling the first mold 3 with the initial screen module, as Figure 16 As shown, the screen module processing method also includes the following steps:

[0093] S500, inject the second glue into the second cavity of the second mold.

[0094] In this step, such as Figure 10 As shown, the second mold 4 includes a third mating part 41 for abutting against the first step surface 141, a fourth mating part 42 for abutting against the second step surface 142, and a fourth connecting part 43 connecting the third mating part 41 and the fourth mating part 42. The second mold 4 is used to cooperate with the step structure 14 to form a second mold cavity. Exemplarily, the third mating part 41 is a frame structure that can be fitted onto the initial screen module. One end of the fourth mating part 42 can abut against the second step surface 142, and the other end of the fourth mating part 42 is connected to the third mating part 41 through the fourth connecting part 43. The side of the fourth connecting part 43 facing the screen module 1 is adapted to the uneven structure, so that the third mating part 41, the fourth connecting part 43, and the fourth mating part 42 can be used to enclose and form the second mold cavity, which can cover the step structure 14 in the extending direction.

[0095] S600, the third mating part of the second mold abuts against the first step surface of the step structure, and the fourth mating part of the second mold abuts against the second step surface of the step structure, so that the second adhesive in the second mold cavity covers the step structure in the extension direction.

[0096] In this step, such as Figure 11 and Figure 13 As shown, before the second adhesive 44 in the second mold cavity is completely cured, the second mold 4 is assembled onto the screen module 1, so that the second adhesive 44 in the second mold cavity covers the stepped structure 14 in the extending direction, and the second adhesive 44 forms a shape that is compatible with the stepped structure 14.

[0097] S700, the second adhesive cures to form a barrier structure.

[0098] In this step, such as Figure 12 As shown, when the second adhesive 44 is fully cured, a barrier structure 15 is formed.

[0099] S800, Remove the second mold.

[0100] In this step, after the second adhesive 44 has fully cured, the second mold 4 is removed to facilitate the formation of the subsequent protective structure 12.

[0101] In this embodiment, compared to directly injecting glue into the step structure 14 to form a blocking structure 15, glue is effectively prevented from entering the initial screen module through the gaps in the step structure 14, thereby improving the reliability of the screen module 1.

[0102] By setting the blocking structure 15 to seal the gaps generated at the step structure 14, the adhesive used to form the protective structure 12 is prevented from entering the initial screen module through the gaps, thereby effectively improving the reliability of the screen module 1. At the same time, the blocking structure 15 is located on the back of the display panel 11, and the blocking structure 15 can also protect the back of the screen module 1 to a certain extent, preventing damage to the back of the screen module 1 caused by squeezing or impact.
