Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a screen module and an electronic device. Background Technology

[0002] Currently, screen modules are fixed using a combination of adhesive application and backing adhesive. The backing adhesive is applied to the edge of the screen glass to secure the screen module to the mid-frame. However, this fixing method results in a wider black border on the screen, affecting the user experience.

[0003] Therefore, using potting compound to fix the screen module and applying adhesive backing to the fixing compound optimizes the connection between the screen module and the mid-frame, reducing the width of the black border. However, the fixing compound can easily seep into the screen module through gaps, causing performance issues. Therefore, reducing the risk of fixing compound flowing into the screen module is a problem that needs to be solved. Utility Model Content

The first folded edge is disposed opposite to the protective plate, and the first folded edge and the light-transmitting panel form the first gap. One side of the second folded edge is connected to the protective plate, and the other side is connected to the first folded edge. The protective plate, the second folded edge and the first folded edge form the accommodating space. One side of the first retaining wall is bonded to the second folded edge and extends along the length of the second folded edge.

[0008] Furthermore, along the length of the first side, the two ends of the second folded edge form two second gaps with the first side, and the second gaps face the light-transmitting panel. The first colloid also includes two second baffles erected on the side of the light-transmitting panel facing the display component, the two second baffles being located at both ends of the first baffle and blocking the two second gaps.

The first adhesive layer is bonded between the light-transmitting panel and the second adhesive layer. The second adhesive layer is bonded between the first adhesive layer, the third adhesive layer and the second folded edge.

[0011] Furthermore, the first adhesive layer, the plurality of second adhesive layers, and the third adhesive layer are flush with the side away from the second folded edge, the first adhesive layer and the plurality of second adhesive layers are flush with the side near the second folded edge, and the third adhesive layer extends to the side of the protective plate and / or the display component away from the light-transmitting panel.

[0012] Furthermore, the display component includes an optical connection layer and a display panel. The display panel includes a backlight layer, a mounting bracket, connecting lines, and a control motherboard. The display panel has a light-emitting surface and a first side edge located on one side of the light-emitting surface. The first side edge is located in the accommodating space. The light-transmitting panel has a light-incident surface. The first side edge is spaced apart from the light-transmitting panel, and the light-emitting surface is connected to the light-incident surface through the optical connection layer.

Simultaneously, a bent portion extends into the first gap formed between the light-transmitting panel and the display component to protect the display component. Therefore, by using a first barrier to block the first gap, the second adhesive can be prevented from entering the first gap, thereby reducing the likelihood of the second adhesive entering the accommodating space. It also prevents stress from being generated between the bent portion and the light-transmitting panel after the second adhesive has cured. Furthermore, by first reinforcing the bent portion with the first adhesive, the amount of second adhesive used can be effectively reduced, lowering operating costs. At the same time, it effectively improves the structural strength of the screen module at the first side position. Attached Figure Description

Figure 2 The outline of the display panel 11 is shown with a dotted line, the outline of the light-transmitting panel 12 is shown with a double dotted line, the outlines of the first barrier 311 and the second barrier 313 are shown with thick dashed lines, and the outline of the covering block 321 is shown with thick solid lines.

[0025] In some implementations, such as Figures 1-3 As shown, the screen module in this embodiment includes a display component 1, a protective shell 2, and a protective adhesive 3. The protective shell 2 is used to protect the display component 1, and the protective adhesive 3 is disposed at the edge of the display component 1 to protect the display component 1 and to fix the display panel 11 and the light-transmitting panel 12 together.

[0026] Figure 4 This is a schematic diagram of the display component 1 and the protective shell 2 in this embodiment. Only a portion of the screen module is shown in the figure, and the outline of the protective shell 2 is shown with thick dashed lines. Figure 5 This is a cross-sectional schematic diagram of the screen module in some implementations of this embodiment. Figure 6 This is a schematic diagram of the structure of the protective adhesive 3 in this embodiment. Figure 7 This is a cross-sectional schematic diagram of the screen module in this embodiment in other embodiments. Figures 5-7 Showing Figure 1 The cross-sectional direction is shown in AA.

[0027] In some implementations, such as Figure 4 and Figure 5As shown, the protective shell 2 includes a bending portion 21. The bending portion 21 is folded to form an accommodating space 22. The display assembly 1 includes an optical connection layer 13, a display panel 11, and a light-transmitting panel 12. The display panel 11 has a light-emitting surface 111 and a first side edge 112 located on one side of the light-emitting surface 111. Further referring to... Figure 2 As shown, the display panel 11 also has three second sides 113 connected in sequence. The first side 112 is used to connect the display panel 11 to the control motherboard 17, so that the control motherboard 17 can control the display panel 11 to generate images. The light-transmitting panel 12 has a light-incident surface 121. The light-emitting surface 111 is connected to the light-incident surface 121 via an optical connection layer 13. The optical connection layer 13 is used to connect the light-emitting surface 111 and the light-incident surface 121 together. Light generated by the display panel 11 enters the light-incident surface 121 through the light-emitting surface 111, and is then displayed through the light-transmitting panel 12.

[0028] Further reference Figure 5 As shown, the first side 112 is located within the receiving space 22; that is, the first side 112 is inserted into the receiving space 22 to protect the first side 112. The aforementioned optical connection layer 13 spacees the first side 112 from the light-transmitting panel 12, creating a gap between the first side 112 and the edge of the light-transmitting panel 12. The edge of the bent portion 21 extends between the first side 112 and the light-transmitting panel 12 (i.e., within this gap), and the edge of the bent portion 21 forms a first slit 41 facing the light-transmitting panel 12 with the opposite side of the light-transmitting panel 12. Further referring to... Figure 3 As shown, the protective adhesive 3 includes a first adhesive 31 and a second adhesive 32. The materials of the first adhesive 31 and the second adhesive 32 can be configured to be the same or different.

[0029] Optionally, such as Figure 5 As shown, the light-transmitting panel 12 includes a glass cover plate, which is used to guide light entering the light-incident surface 121 to the side opposite to the display panel 11. The optical bonding layer 13 includes, but is not limited to, an adhesive film 131 and a polarizer 132. The polarizer 132 is used to change the polarization direction of light. One side of the polarizer 132 is disposed on the light-emitting surface 111, and the other side is bonded to the light-incident surface 121 of the glass cover plate through the adhesive film 131. The adhesive film 131 has good light transmittance. The adhesive film 131 can be in the form of a solid optical adhesive film (Optically Clear Adhesive) or a liquid optical adhesive (Optically Clear Resin), etc.

[0030] Specifically, the edge thickness of the bent portion 21 is less than the thickness of the optical connection layer 13, so that the aforementioned first gap 41 is formed between the edge region of the bent portion 21 and the edge region of one side of the light-transmitting panel 12. The first gap 41 has an opening through which the side of the optical connection layer 13 faces the side of the screen module.

[0031] Further reference Figure 2 and Figure 6 As shown, the first colloid 31 includes a first barrier 311. The first barrier 311 is erected on the light-receiving surface 121 and extends along the first side 112. One side of the first barrier 311 is spaced apart from the edge of the light-transmitting panel 12, and the other side is bonded to the bent portion 21 and blocks the first gap 41. The second colloid 32 includes a covering block 321, which extends along the length of the first side 112 and covers the first barrier 311 and at least part of the bent portion 21. In this embodiment, the first barrier 311 can prevent the second colloid 32 from flowing into the receiving space 22 through the first gap 41.

[0032] In summary, the screen module in this embodiment uses a protective shell 2 to protect the first side 112 of the display panel 11, so that the display panel 11 can be equipped with connecting devices through the first side 112. Simultaneously, an optical connecting layer 13 connects the light-emitting surface 111 and the light-receiving surface 121, allowing light generated by the display panel 11 to enter the light-transmitting panel 12 through the optical connecting layer 13. In this configuration, the optical connecting layer 13 separates the display panel 11 from the light-transmitting panel 12, resulting in a first gap 41 between the bent portion 21 and the light-transmitting panel 12. Therefore, by using the first barrier 311 to block the first gap 41, when forming the covering block 321 using potting adhesive, the second adhesive 32 can be prevented from entering the first gap 41, thereby reducing the occurrence of the second adhesive 32 entering the accommodating space 22. Furthermore, it also prevents stress from being generated between the bent portion 21 and the light-transmitting panel 12 after the second adhesive 32 has cured. On the other hand, by first reinforcing the bent portion 21 with the first colloid 31, the amount of the second colloid 32 can be effectively reduced, thereby lowering the cost of use. At the same time, it effectively improves the structural strength of the screen module at the first side 112 position.

[0033] In some implementations, such as Figures 4-5As shown, the protective shell 2 includes a protective plate 23, which covers the side of the display panel 11 facing away from the light-transmitting panel 12. The bending portion 21 includes a first folded edge 211 and a second folded edge 212 extending along the length of the first side edge 112. The first folded edge 211 is disposed opposite to the protective plate 23, and forms a first gap 41 with the light-transmitting panel 12. One side of the second folded edge 212 is connected to the protective plate 23, and the other side is connected to the first folded edge 211. The protective plate 23, the second folded edge 212, and the first folded edge 211 form an accommodating space 22. That is, one side of the second folded edge 212 is connected to the protective plate 23, and the other side is folded towards the light-incident surface 121. The first folded edge 211 is folded from the second folded edge 212 towards the center of the first gap 41, and forms the first gap 41 with the light-incident surface 121. Further referencing... Figure 6 As shown, one side of the first retaining wall 311 is bonded to the second folded edge 212 and extends along the length direction of the second folded edge 212.

[0034] Specifically, such as Figure 5 As shown, the first folded edge 211 is parallel to the light-incident surface 121, and the second folded edge 212 is perpendicular to the light-incident surface 121. The connection points between the first folded edge 211 and the second folded edge 212, as well as the connection point between the second folded edge 212 and the guard plate 23, are rounded. The height direction of the first retaining wall 311 is parallel to the width direction of the second folded edge 212. In this embodiment, the second folded edge 212 cooperates with the first retaining wall 311, increasing the rigidity of the first side edge 112 in the height direction of the second folded edge 212 (e.g., ...). Figure 6 (As shown by the middle arrow), to avoid squeezing the first side 112 after the screen module is assembled with the middle frame.

[0035] Figure 8 This is a schematic diagram of the process flow of the screen module in some implementations of this embodiment. Figure 8 States IIa, IIb and IIc illustrate the manufacturing process for the first retaining wall 311.

[0036] In some implementations, such as Figure 6 and Figure 8 As shown, the first retaining wall 311 includes multiple adhesive layers 312, which are stacked sequentially along the height direction of the second fold 212 and extend along the length direction of the second fold 212.

[0037] Specifically, in this embodiment, the first barrier 311 is manufactured by stacking layers one after another, so that the first barrier 311 is simultaneously bonded to the bending portion 21 and the light-incident surface 121, effectively improving the sealing performance of the first barrier 311 to the first gap 41. In addition, the number of adhesive layers 312 can be adjusted according to the thickness of the display panel 11, improving the flexibility of the assembly process.

[0038] Figure 9 This is a schematic diagram of the process flow of the screen module in some other embodiments of this example. Figure 9 States IIIa and IIIb illustrate the manufacturing process for the covering block 321. Figure 10 yes Figure 4 A magnified view of region C in the middle. Figure 10 The protective shell 2 is shown with a thick solid line, and the first colloid 31 is shown with a thick dashed line.

[0039] In some implementations, such as Figure 6 As shown, the plurality of adhesive layers 312 include at least one first adhesive layer 3121, a plurality of second adhesive layers 3122, and at least one third adhesive layer 3123. The first adhesive layer 3121 is located at the bottom of the first barrier 311 and is disposed opposite to the first gap 41. The first adhesive layer 3121 is bonded between the light-receiving surface 121 and the second adhesive layer 3122. The second adhesive layer 3122 is bonded between the first adhesive layer 3121, the third adhesive layer 3123, and the second folded edge 212.

[0040] Optionally, the first adhesive layer 3121 is singly distributed and its thickness is configured to be less than the width of the first gap 41, so that the first adhesive layer 3121 does not contact the second folded edge 212, thereby improving the curing speed of the first adhesive layer 3121. The bottom of the second adhesive layer 3122 is bonded to the first adhesive layer 3121, the top is bonded to the third adhesive layer 3123, and the sides of the second adhesive layer 3122 are bonded to the second folded edge 212. This ensures that the opening of the first gap 41 is blocked by the first adhesive layer 3121 and the second adhesive layer 3122, thereby improving the curing speed of the first retaining wall 311.

[0041] Optionally, the first adhesive layer 3121 is one in number and its thickness is greater than or equal to the width of the first gap 41, such that the first adhesive layer 3121 is simultaneously bonded to the second folded edge 212 and the light-receiving surface 121. The bottom of the second adhesive layer 3122 is bonded to the first adhesive layer 3121, its top is bonded to the third adhesive layer 3123, and its sides are bonded to the second folded edge 212. Thus, the first adhesive layer 3121, the second adhesive layer 3122, and the second folded edge 212 are bonded together in pairs, improving the sealing performance of the first retaining wall 311.

[0042] In some implementations, such as Figure 6 As shown, the first adhesive layer 3121, the plurality of second adhesive layers 3122 and the third adhesive layer 3123 are flush with the side away from the second folded edge 212, the first adhesive layer 3121 and the plurality of second adhesive layers 3122 are flush with the side near the second folded edge 212, and the third adhesive layer 3123 extends to the side of the protective plate 23 and / or the display panel 11 away from the light-emitting surface 111 on the side near the second folded edge 212.

[0043] Specifically, further refer to Figure 9 As shown, in this embodiment, the side of the first barrier 311 facing away from the first side 112 is flush with the side of the second adhesive 32. During the application of the second adhesive 32, this effectively reduces the resistance of the second adhesive 32 and minimizes the occurrence of pores within the covering block 321. There is one first adhesive layer 3121, and the thickness of this first adhesive layer 3121 is consistent with the width of the first gap 41. One side of the third adhesive layer 3123 covers the connection between the second folded edge 212 and the protective plate 23. The third adhesive layer 3123 can improve the stability of the connection between the first barrier 311 and the protective shell 2. Furthermore, when the side of the display panel 11 facing away from the light-emitting surface 111 is exposed outside the protective plate 23 (e.g....), Figure 10 As shown in region I), a third gap 43 is formed between the protective plate 23 and the display panel 11. The third adhesive layer 3123 can also prevent the second adhesive 32 from entering the accommodating space 22 through the third gap 43.

[0044] In some implementations, such as Figure 10 As shown, along the length of the first side 112, the two ends of the second folded edge 212 form two second gaps 42 with the first side 112, and the second gaps 42 face the light-transmitting panel 12. These second gaps 42 are perpendicular to the first gap 41. Further referencing... Figure 2 As shown, the first colloid 31 also includes two second baffles 313 erected on the light-receiving surface 121. The two second baffles 313 are located at both ends of the first baffle 311 and block the two second gaps 42.

[0045] Specifically, in this embodiment, the two ends of the second folded edge 212 extend to the two ends of the first side edge 112, and the two second baffles 313 are bent along the corner of the display panel 11. This prevents the second colloid 32 from entering the accommodating space 22 from the two ends of the second folded edge 212.

[0046] Figure 11 yes Figure 3 A magnified view of region B in the middle.

[0047] In some implementations, such as Figure 5 and Figure 11 As shown, the display panel 11 includes a backlight layer 14, a mounting bracket 15, a connecting cable 16, and a control board 17. The mounting bracket 15 has a receiving area 152 and a connecting window 151. At least a portion of the backlight layer 14 is disposed in the receiving area 152, and the mounting bracket 15 is located between the light-transmitting panel 12 and the control board 17. A protective plate 23 covers the control board 17. One end of the connecting cable 16 is electrically connected to one side of the backlight layer 14 located on the first side 112, and the other end passes through the connecting window 151 and connects to the control board 17. The connecting window 151 is located between two second gaps 42.

[0048] Specifically, the mounting bracket 15 is a plate-like structure, including a first plate edge, which is bent to form the aforementioned receiving area 152. A connecting window 151 is opened on the side of the receiving area 152 away from the light-transmitting panel 12 and near the second folded edge 212. The backlight layer 14 includes a light guide plate and multiple light strips, which are located on the side of the light guide plate near the connecting window 151. The connecting line 16 is a flexible circuit board. One end of the flexible circuit board is connected to the backlight layer 14 to power the multiple light strips, and the other end passes through the connecting window 151 along the inner wall of the mounting bracket 15, and then extends along the outer wall of the mounting bracket 15 to the control main board 17. The control main board 17 is also used to connect with other components of the electronic device. The display panel 11 also includes a color filter 18, one side of which abuts against the outer surface of the first plate edge, and the other side abuts against the first folded edge 211.

[0049] In this embodiment, the connecting window 151 is set in the accommodating space 22. After the first gap 41, the second gap 42 and the third gap 43 are sealed by the first colloid 31, the second colloid 32 will not enter the accommodating area 152 through the accommodating space 22, thus preventing the second colloid 32 from contacting the backlight layer 14 and the connecting line 16.

[0050] In some implementations, such as Figures 8-9 As shown, the protective adhesive 3 is configured such that, before curing, the first adhesive 31 has less fluidity than the second adhesive 32, and the first adhesive 31 is a photocurable adhesive. In this embodiment, the first adhesive 31 is formed on the screen module by dispensing, and the second adhesive 32 is formed on the screen module by potting.

[0051] It is easy to understand that the first colloid 31 in this embodiment has low fluidity. After the first colloid 31 is extruded from the dispensing head 71, it does not easily disperse, so that the operator can use the curing lamp 72 to cure the first colloid 31 in a timely manner. In contrast, the second colloid 32 has high fluidity, so that the second colloid 32 can fill the gaps between the display component 1, the protective shell 2, and the first colloid 31 during dispensing.

[0052] Optionally, the first colloid 31 can be an ultraviolet light curing adhesive. The curing lamp 72 is an ultraviolet curing lamp 72. The second colloid 32 can be a GOM adhesive. Its components include, but are not limited to, silicone, epoxy resin, and adhesives.

[0053] In some implementations, such as Figures 8-9As shown, the protective adhesive 3 is configured such that, before curing, the viscosity of the first adhesive 31 is greater than that of the second adhesive 32. This increases the sealing performance of the first adhesive 31 and improves the bonding strength between the first adhesive 31 and the light-receiving surface 121 and the second folded edge 212, further increasing the stiffness of the first side edge 112 in the height direction of the second folded edge 212. Simultaneously, it facilitates the formation of the encapsulated block 321 using a potting method, allowing for a smooth mold-opening process.

[0054] Furthermore, the viscosity of the first colloid 31 is 3.8~50 mPa·s, and the viscosity of the second colloid 32 is 1.1~2 mPa·s. In this embodiment, the viscosities of the first colloid 31 and the second colloid 32 are configured within a certain range to facilitate the formation of the first barrier wall 311 and the coating block 321 by dispensing and potting, respectively.

[0055] In an alternative implementation, the screen module in the above embodiments can be applied to an electronic device. This electronic device includes, but is not limited to, devices such as mobile phones or laptops. The electronic device also includes a mid-frame. Further referring to... Figure 5 and Figure 6 As shown, the top of the covering block 321 is provided with adhesive 6. This adhesive 6 is used to bond to the mid-frame, thus assembling the screen module and the mid-frame. In this form, as... Figure 6 The distance L1 is the width of the black border area of ​​the screen module. In this embodiment, the distance L1 can be controlled to be around 0.75mm.

[0056] In other implementations, such as Figure 7 As shown, the adhesive 6 is directly applied to the edge of the light-transmitting panel 12. Compared to the way the adhesive 6 is applied in the above embodiment, the black border of the screen module in this embodiment is wider (distance L2 is greater than distance L1). When the electronic device is a tablet computer, the range of L2 is 7mm-11mm, and when the electronic device is a mobile phone, the range of L2 is 3.5mm-4.5mm.

[0057] In summary, the electronic device in this embodiment uses a protective shell 2 to protect the first side 112 of the display panel 11, so that the display panel 11 can be equipped with connecting devices through the first side 112. Simultaneously, an optical connecting layer 13 connects the light-emitting surface 111 and the light-receiving surface 121, allowing light generated by the display panel 11 to pass through the optical connecting layer 13 and enter the light-transmitting panel 12. In this configuration, the optical connecting layer 13 separates the display panel 11 from the light-transmitting panel 12, resulting in a first gap 41 between the bent portion 21 and the light-transmitting panel 12. Therefore, by using the first barrier 311 to block the first gap 41, when forming the covering block 321 using potting adhesive, the second adhesive 32 can be prevented from entering the first gap 41, thereby reducing the occurrence of the second adhesive 32 entering the accommodating space 22. Furthermore, it also prevents stress from being generated between the bent portion 21 and the light-transmitting panel 12 after the second adhesive 32 has cured. On the other hand, by first reinforcing the bent portion 21 with the first colloid 31, the amount of the second colloid 32 can be effectively reduced, thereby lowering the cost. Simultaneously, it effectively improves the structural strength of the screen module at the first side 112 position and effectively reduces the width of the black border of the screen module.

[0058] Figure 12 This is a flowchart illustrating the screen module assembly method of this embodiment.

[0059] like Figure 12 As shown, in an optional implementation, the screen module in the above embodiments can be assembled in the following manner.

[0060] Step S100: The first colloid 31 is applied along the length of the first side 112 to the light-incident surface 121 to form a first barrier that adheres to the bent portion 21 and blocks the first gap 41. The light-incident surface 121 is formed on the side of the light-transmitting panel 12 facing the display panel 11.

[0061] Preferably, such as Figure 2 As shown, a first colloid 31 is applied to both ends of the first side 112 to form the two second barriers 313, thereby blocking the second gap 42.

[0062] Furthermore, such as Figure 8 As shown, step S100 specifically includes: Step S110: Apply the first adhesive layer 3121 to the opening of the first gap 41 and cure it with a curing lamp 72. Drive the glue head 71 to move along the length of the opening and drive the curing lamp 72 to follow the movement, so as to increase the processing speed of the first retaining wall 311.

[0063] Step S120: Multiple second adhesive layers 3122 are sequentially stacked on the first adhesive layer 3121 and cured by a curing lamp 72, wherein the edges of the multiple second adhesive layers 3122 are bonded to the second folded edge 212. The multiple second adhesive layers 3122 are arranged sequentially along the width direction of the second folded edge 212.

[0064] Step S130: Apply a third adhesive layer 3123 to the second adhesive layer 3122, and bond the third adhesive layer 3123 to the top surface of the protective plate 23 or the display panel 11 in the width direction of the third adhesive layer 3123, and cure it by curing lamp 72.

[0065] Optionally, in order to increase the width of the third adhesive layer 3123, the third adhesive layer 3123 can be applied twice in the width direction of the first adhesive layer 3121 to ensure that the third adhesive layer 3123 can cover the top edge of the display panel 11 and the edge of the protective plate 23.

[0066] Preferably, the diameter of the glue nozzle 71 is configured to be 0.2mm-0.25mm, and the glue outlet of the glue nozzle 71 is inclined and maintains a small gap with the light-receiving surface 121, so that the adhesive layer 312 is flatter after the first glue 31 is extruded. The thickness of the multiple adhesive layers 312 is controlled to be 0.1mm-0.2mm, the width is controlled to be greater than or equal to 0.25mm, and the distance between the first adhesive layer 3121 and the edge of the light-transmitting panel 12 is greater than or equal to 0.5mm. Thus, as Figure 9 As shown, after the multilayer adhesive layers 312 are stacked, the second colloid 32 is ensured to flow from the top of the first baffle 311 to the bottom of the cavity 51, so as to avoid the gap between the third adhesive layer 3123 and the top of the cavity 51 being too small.

[0067] Step S200: The forming mold 5 is set on the first side 112. The bent part 21 and the first retaining wall 311 are located in the cavity 51 of the forming mold 5.

[0068] Step S300: Inject the second colloid 32 into the cavity 51 so that the second colloid 32 covers the first barrier 311 and at least part of the bent portion 21.

[0069] Step S400: Disassemble the molding mold 5.

[0070] Step S400 includes: such as Figure 10 As shown in state IIIb, the area of ​​the second colloid 32 located at the gate is cut off, and the top of the coating block 321 is ground flat. The backing adhesive 6 is then attached to the top of the coating block 321.

[0071] In summary, the screen module assembly method in this embodiment stacks multiple adhesive layers 312 one by one to form a first barrier 311. Operators can adjust the height of the first barrier 311 according to the thickness of the display panel 11, improving the flexibility of the assembly process. Furthermore, reinforcing the bent portion 21 with the first adhesive 31 effectively saves on the amount of second adhesive 32 used, reducing operating costs. Simultaneously, it effectively improves the structural strength of the screen module at the first side 112 position, reducing the width of the black border of the screen module. Moreover, by using the first barrier 311 to cover the first gap 41, when forming the covering block 321 using potting adhesive, it prevents the second adhesive 32 from entering the first gap 41, thereby reducing the occurrence of the second adhesive 32 entering the accommodating space 22.

[0072] In another alternative implementation, such as Figure 2 As shown, the screen module in the above embodiment can be assembled in the following manner. The screen module assembly method includes the above-described step S100.

[0073] Following step S100: The molding die 5 is positioned at the first side 112 and the three second sides 113. That is, the first side 112 and the three second sides 113 are simultaneously filled with adhesive. This causes the second adhesive 32 to surround the edge of the light-receiving surface 121, thereby increasing the fixing effect of the second adhesive 32.

[0074] Optionally, the three second sides 113 are not provided with the first colloid 31, so the height and width of the coating block 321 corresponding to the three second sides 113 are smaller than the coating block 321 corresponding to the first side 112. This reduces the amount of second colloid 32 used.

[0075] In yet another alternative implementation, such as Figure 3 As shown, the screen module in the above embodiment can be assembled in the following manner. The protective shell 2 also includes three protective covers 24. The three protective covers 24 respectively cover the three second sides 113 (e.g., Figure 4 and Figure 10(As shown). A first adhesive 31 is applied sequentially around the first side 112 and the three second sides 113 to form four first barriers 311 and four second barriers 313. Two adjacent first barriers 311 are connected by a second barrier 313, which is located at the corner of the display panel 11. A third adhesive layer 3123 is applied to the top edge of the display panel 11 and the protective shell 2. In this configuration, the first adhesive 31 can also block the gaps between the protective cover 24 and the second side 113, preventing the second adhesive 32 from entering. The molding mold 5 is positioned at the first side 112 and the three second sides 113. That is, adhesive is applied to the first side 112 and the three second sides 113 simultaneously. This causes the second adhesive 32 to surround the edge of the light-receiving surface 121 and cover the first adhesive 31. This further enhances the protective effect of the protective adhesive 3 on the screen module.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principle of this utility model should be included within the protection scope of this utility model.
