[0002] For electronic devices with display modules, a high screen-to-body ratio has always been a key element of competitiveness. Under the same conditions, the smaller the black border width of the display module, the higher the screen-to-body ratio. A higher screen-to-body ratio reduces distractions in the user's field of view when using the electronic device, providing a more immersive user experience. Therefore, reducing the black border width of electronic device display modules is a challenge designers must address. Utility Model Content
[0003] An embodiment of the present application provides an electronic device having a smaller black border width on a display module, which can provide a better user experience.

[0005] The electronic device provided in the application is characterized in that the light-transmitting cover plate and the screen stack are connected with the shell through the edge sealing member. In the processing, the edge sealing member can be prepared on the light-transmitting cover plate and the screen stack first, and then the combination of the light-transmitting cover plate, the screen stack and the edge sealing member is fixedly connected with the shell. The edge sealing member is bonded to the side surface of the screen stack, which can protect the screen stack during the process of loading the screen stack into the shell, so that the screen stack is not worried about being scratched by the shell. In addition, the edge sealing member is a flexible member, so there is no need to reserve a gap between the edge sealing member and the screen stack. In the present scheme, the gap between the edge sealing member and the screen stack is cancelled, so that the black edge width of the display module can be reduced. Furthermore, at least one first connecting part is arranged on the surface of the edge sealing member facing the bearing plate, and a second connecting part matched with the first connecting part is arranged on the bearing plate. The combination of the light-transmitting cover plate, the screen stack and the edge sealing member is fixedly connected with the shell through the connection between the first connecting part and the second connecting part. The connection structure of the combination and the shell in the thickness direction of the electronic device is increased, the connection strength of the combination and the shell in the thickness direction of the electronic device is improved, so that the requirement of the edge sealing member to resist side impact can be reduced, and thus the width of the edge sealing member can be appropriately reduced, thereby facilitating the further reduction of the black edge width of the display module. Therefore, compared with the electronic device adopting the glue filling scheme, the electronic device provided in the application can significantly reduce the black edge of the display module and improve the screen-to-body ratio of the display module.

[0007] In a possible embodiment, along the thickness direction of the electronic device, the orthographic projection of the first connecting part on the light-transmitting cover plate does not overlap with the orthographic projection of the screen stack on the light-transmitting cover plate, thereby facilitating the reduction of the influence of the stress generated by the connection of the first connecting part and the second connecting part on the screen stack.
[0008] In a possible embodiment, the first connecting part includes a positioning column, and the second connecting part includes a positioning hole; or the first connecting part includes a positioning hole, and the second connecting part includes a positioning column; the positioning hole is a blind hole, and the bottom surface of the blind hole or the surface of the positioning column facing the positioning hole is provided with a first adhesive layer, and the bottom surface of the blind hole and the surface of the positioning column facing the positioning hole are bonded through the first adhesive layer.

[0010] In one possible embodiment, the first connecting portion includes a positioning post, and the second connecting portion includes a positioning hole, wherein the positioning hole is a through hole. A snap-fitting portion is provided on the outer surface of the positioning post, projecting radially from the outer circumference of the positioning post. The snap-fitting portion is configured to expose the positioning hole and snap into engagement with the housing. The snap-fitting portion connects the first and second connecting portions, thereby achieving a fixed connection between the light-transmitting cover plate, the screen stack, the edge seal, and the middle frame, thereby providing a more reliable connection between the light-transmitting cover plate, the screen stack, the edge seal, and the middle frame.
[0011] In a possible embodiment, the radial dimension of the clamping portion gradually decreases along the direction from the light-transmitting cover plate toward the screen stack, thereby making it easier for the clamping portion to pass through the second connecting hole.
[0012] In one possible embodiment, the first connecting portion includes a positioning post, and the second connecting portion includes a positioning hole. The electronic device includes multiple screws, and the housing includes a fixing through-hole connected to the positioning hole. Each screw is configured to pass through the fixing through-hole and securely connect to the positioning post. This solution provides a more convenient and reliable connection between the light-transmitting cover, screen stack, and edge seals, and the midframe.
[0013] In a possible embodiment, the elastic modulus of the positioning column is greater than or equal to 1.5 GPa, thereby facilitating the insertion of the first protrusion into the second connection hole.
[0014] In a possible embodiment, a second adhesive layer is provided on the surface of the shell facing the screen stack or the surface of the edge sealing member facing away from the light-transmitting cover plate. The second adhesive layer has an avoidance hole for avoiding the positioning column. The edge sealing member and the shell are bonded through the second adhesive layer, and the positioning column passes through the avoidance hole and is fixedly connected to the positioning hole corresponding to the positioning column, so that the connection between the light-transmitting cover plate, the screen stack and the edge sealing member and the middle frame is more reliable.

DETAILED DESCRIPTION
[0057] An embodiment of the present application provides an electronic device, which is a type of electronic device with a display function. For example, the electronic device can be a wearable device, such as a smart watch, a smart bracelet, etc. The electronic device can also be a mobile phone, a laptop computer, a tablet computer, an in-vehicle device, augmented reality (AR) glasses, an AR helmet, virtual reality (VR) glasses, or a VR helmet, etc. For the sake of convenience, the following detailed description is based on the example of a mobile phone as the electronic device.
[0058] Figure 1 For an exploded view of an electronic device, see Figure 1, an electronic device generally includes a display module 100, a circuit board 200 and a housing 300, etc., wherein the display module 100 includes a light-transmitting cover plate 110 and a screen laminate 120, etc., the light-transmitting cover plate 110 and the screen laminate 120 are bonded together by glue, and the housing 300 is used to carry multiple components including the display module 100 and the circuit board 200. For example, the material of the light-transmitting cover plate 110 can be glass, and the light-transmitting cover plate 110 and the screen laminate 120 can be bonded together by an optically clear adhesive layer (OCA). For example, the housing 300 can be Figure 1 Specifically, the housing 300 is in the shape of a box with an opening, the circuit board 200 and other components are accommodated in the housing 300, and the display module 100 is covered and fixed to the opening of the housing 300.
[0059] In some embodiments, as Figure 2a The cross-sectional structure diagram of an electronic device shown in FIG. 3 shows a housing 300 of a split structure, comprising a middle frame 310 and a back cover 320 connected together. The back cover 320 is also called a battery cover. Figure 2b for Figure 2a A partial enlarged view. In a specific implementation, the back cover 320 is disposed on one side of the middle frame 310 and is fixedly connected to the middle frame 310. The transparent cover 110 is disposed on a side of the middle frame 310 away from the back cover 320 and is fixed to the middle frame 310. The transparent cover 110, the middle frame 310, and the back cover 320 can enclose a storage space, and the screen stack 120, circuit board 200, and other electronic components are all disposed within this storage space.
[0060] The display module 100 includes a display area and a non-display area. The non-display area is generally located at the edge of the display area. The black border of the display module 100 is the non-display area, that is, the portion from the edge of the display area of the display module 100 to the inner edge of the side wall of the housing 300. The width of the black border of the display module 100 is affected by the connection structure and connection process between the display module 100 and the housing 300. For example, please refer to Figure 2c The following is a schematic diagram of a partial cross-sectional structure of an electronic device. Figure 2c As shown, in this electronic device, the housing 300 includes a middle frame 310 and a back cover 320. The translucent cover plate 110 is bonded to the middle frame 310 with a caulking adhesive 400, and the screen laminate 120 is bonded to the middle frame 310 with a back adhesive. To ensure that the screen laminate 120 can enter the middle frame 310 and does not collide with the middle frame 310 during the process, a gap d is required between the edge of the screen laminate 120 and the inner sidewall of the middle frame 310. The presence of this reserved gap d further increases the width of the black border of the display module, resulting in a poor user experience.
[0061] Based on this, an embodiment of the present application provides an electronic device having a display module with a smaller black border, a higher screen-to-body ratio, and a better user experience. To make the purpose, technical solutions, and advantages of this application more clear, this application will be further described in detail below with reference to the accompanying drawings.

As used in the specification and appended claims of this application, the singular expressions "a", "an", "said", "above", "the", and "this" are intended to also include expressions such as "one or more", unless the context clearly indicates otherwise.
[0063] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized.

[0064] Figure 3a This is a schematic diagram of the three-dimensional structure of an electronic device provided in this application. Figure 3b for Figure 3a Exploded view of the electronic device shown. Figure 3a and Figure 3b As shown, the electronic device provided by the present application includes a transparent cover plate 1, a screen laminate 2, an edge seal 3 and a housing 4. For example, the transparent cover plate 1 can be a glass cover plate. Along the thickness direction H of the electronic device, the edge of the transparent cover plate 1 is fixed to the housing 4, and a receiving space is formed between the transparent cover plate 1 and the housing 4. The transparent cover plate 1 can be bonded to the screen laminate 2 through an optical adhesive layer, and the screen laminate 2 is located on the surface of the transparent cover plate 1 facing the housing 4, wherein, Figure 3a and Figure 3bThe dashed box in the figure illustrates the screen laminate 2 located on the side of the transparent cover plate 1 facing the housing 4. The transparent cover plate 1 is fixed to the light-emitting surface of the screen laminate 2, and its edge extends beyond the edge of the screen laminate 2. That is, the area of the transparent cover plate 1 is larger than that of the screen laminate 2. The orthographic projection of the screen laminate 2 on the surface of the transparent cover plate 1 falls within the edge of the transparent cover plate 1 and is spaced a certain distance from the edge of that surface. The orthographic projection of the screen laminate 2 on the surface of the transparent cover plate 1 completely covers the screen laminate 2. It is easy to understand that the orthographic projection of the screen laminate 2 on the surface of the transparent cover plate 1 refers to the projection of the screen laminate 2 obtained by taking one surface of the transparent cover plate 1 as the projection plane and making the projection line perpendicular to that surface of the transparent cover plate 1. The edge seal 3 is disposed between the transparent cover plate 1 and the housing 4. Specifically, the edge seal 3 is bonded to the surface of the transparent cover plate 1 facing the screen laminate 2, and the edge seal 3 covers and is bonded to the side surfaces of the screen laminate 2. That is to say, the screen stack 2 is fixed in the space enclosed by the transparent cover 1 and the edge sealing member 3, and the edge of the display module is sealed by the edge sealing member 3. The edge sealing member 3 is bonded to at least the surface of the transparent cover 1 facing the screen stack 2 and the side of the screen stack 2. Exemplarily, the edge sealing member 3 can be prepared by a glue filling process or other processes. The shell 4 includes a middle frame 410 and a back cover 420, and the middle frame 410 and the back cover 420 are arranged along the thickness direction H of the electronic device and fixedly connected. The middle frame 410 includes a frame 41 and a supporting plate 42, and the frame 41 is arranged around the edge of the supporting plate 42 and fixedly connected to the supporting plate 42, and the frame 41 protrudes from the two side surfaces of the supporting plate 42. The transparent cover 1 and the screen stack 2 are arranged on the side of the supporting plate 42 away from the back cover 420. For example, the middle frame 410 and the back cover 420 can be integrally formed, that is, the housing 4 is an integrally formed structure; the middle frame 410 and the back cover 420 can also be separate components, in which case the middle frame 410 and the back cover 420 are fixedly connected together. In specific implementations, holes, steps, etc. can be provided on the supporting plate 42 as needed to facilitate the placement of various components in the housing 4.
[0065] In some embodiments, as Figure 3b As shown, the edge seal 3 includes at least one first connecting portion 31, and the housing 4 includes at least one second connecting portion 43. Any first connecting portion 31 is either a positioning hole or a positioning post, and any second connecting portion 43 is the other of the two. The positioning hole is used to accommodate the positioning post, and the positioning post is used to extend into the positioning hole along the thickness direction H of the electronic device and be fixedly connected to the positioning hole, thereby connecting the edge seal 3 to the housing 4, and further achieving the connection between the combination of the transparent cover plate 1, the screen laminate 2, and the edge seal 3 and the housing 4 in the thickness direction H of the electronic device. It is not difficult to understand that the thickness direction H of the electronic device is also the arrangement direction of the transparent cover plate 1 and the screen laminate 2.
[0066] In the electronic device provided in the embodiment of the present application, the light-transmitting cover plate 1 and the screen laminate 2 are connected to the housing 4 through the edge sealing member 3. During the processing, the edge sealing member 3 can be first prepared on the light-transmitting cover plate 1 and the screen laminate 2, and then the combination of the light-transmitting cover plate 1, the screen laminate 2 and the edge sealing member 3 is fixedly connected to the housing 4. The edge sealing member 3 is bonded to the side of the screen laminate 2 and can protect the screen laminate 2 during the process of installing the screen laminate into the housing. Therefore, there is no need to worry about the screen laminate being scratched by the housing. In addition, the edge sealing member 3 can be a flexible member, so there is no need to retain a gap between the edge sealing member 3 and the screen laminate 2. In this solution, the gap between the edge sealing member 3 and the screen laminate 2 is eliminated, so the width of the black edge of the display module 100 can be reduced. Furthermore, at least one first connection portion 31 is provided on the surface of the edge seal 3 facing the housing 4, and a second connection portion 43 matching the first connection portion 31 is provided on the housing 4. The combination of the transparent cover plate 1, the screen stack 2 and the edge seal 3 is fixedly connected to the housing 4 through the connection between the first connection portion 31 and the second connection portion 43, thereby increasing the connection structure between the above combination and the housing 4 in the thickness direction H of the electronic device, and improving the connection strength between the combination and the housing 4 in the thickness direction H of the electronic device, thereby reducing the ability of the edge seal 3 to resist side impact, and thus the width of the edge seal 3 can be appropriately reduced, which is conducive to further reducing the width of the black edge of the display module. Therefore, the electronic device provided by the present application can significantly reduce the black edge of the display module 100 and increase the screen-to-body ratio of the display module compared to the electronic device using the glue filling solution. In some embodiments, the black edge width of the display module 100 of the electronic device using the glue filling solution is 0.8 to 1 mm, while in the electronic device provided by the present application, the black edge width of the display module 100 is 0.2 to 0.25 mm.
[0067] Figure 4 This is a partial cross-sectional view of a housing 4 in an electronic device provided in an embodiment of the present application. Figure 4 As shown, when the above-mentioned shell 4 is specifically set up, at least one second connection part 43 can be formed on the supporting plate 42, or at least one second connection part 43 can be formed on the back cover 420, wherein, when the second connection part 43 is formed on the back cover 420, a through hole for the second connection part 43 to pass through is provided on the supporting plate 42.
[0068] Figure 5a This is a front view of an electronic device provided in an embodiment of the present application. Figure 5b for Figure 5a AA section view of the Figure 5a and Figure 5bAs shown, exemplarily, the edge seal 3 and the screen stack 2 are fixed on the surface of the transparent cover plate 1 facing the shell 4, and the edge seal 3 is located between the circumferential side of the screen stack 2 and the middle frame 41, and the edge seal 3 is connected to the circumferential side of the screen stack 2. The first connecting portion 31 protrudes toward the shell 4 along the thickness direction H of the electronic device to form a positioning column, and the second connecting portion 43 is a surface of the supporting plate 42 facing the transparent cover plate 1 and recessed toward the surface away from the transparent cover plate 1 to form a positioning hole. The first connecting portion 31 extends into the second connecting portion 43 and is fixedly connected, thereby achieving the connection and fixation of the edge seal 3 to the shell 4. Along the thickness direction H, the orthographic projection of the screen stack 2 on the transparent cover plate 1 does not overlap with the orthographic projection of the first connecting portion 31 on the transparent cover plate 1. Here, the second connecting portion 32 is a blind hole. The first connecting portion 31 and the second connecting portion 32 can be connected and fixed by gluing, interference fit, etc.
[0069] exist Figure 5b In the illustrated embodiment, the axis m of the positioning post and the positioning hole both extend along the thickness direction H of the electronic device, and the first connecting portion 31 and the second connecting portion 43 can be connected and fixed along the thickness direction H of the electronic device. However, in the embodiments of the present application, the positioning post is used to extend into the positioning hole along the thickness direction H of the electronic device and be fixedly connected to the positioning hole. This should be understood broadly, that is, the axis direction of the positioning post and the positioning hole is not limited to along the thickness direction H of the electronic device. As long as the distance between the end of the positioning post away from the transparent cover plate and the transparent cover plate changes along the thickness direction H of the electronic device during insertion into the positioning hole, it can be sufficient. For example, in this embodiment, the first connecting portion 31 is the positioning post, and the second connecting portion 43 is the positioning hole. Here, the screen laminate 2 may include an optically clear adhesive (OCA), a polarizer (POL), a display panel (panel), a backing film (BF), an adhesive layer (e.g., a silicone gel layer), and a copper layer, arranged in sequence away from the transparent cover plate.
[0070] For example, Figure 6a As shown, in some embodiments, the axis m of the positioning post as the first connection part 31 and the positioning hole as the second connection part 43 are both at an angle to the thickness direction H of the electronic device. In this case, when the first connection part 31 and the second connection part 43 are connected and fixed, the positioning post can be deformed to a certain extent so that the positioning post can be smoothly inserted into the positioning hole. Figure 6b As shown, in other embodiments, the axis m of the positioning post is in the shape of a broken line, with a section thereof extending along the thickness direction H of the electronic device, etc. As long as the positioning post can extend into the positioning hole along the thickness direction H of the electronic device and be fixedly connected to the positioning hole, all of these are sufficient, and no further examples are given here.
[0071] It is not difficult to see from the above embodiments that the positioning hole can be a blind hole, such asFigure 6a As shown; the positioning hole can also be a through hole, such as Figure 6b As long as the positioning pin can be inserted into the corresponding positioning hole, it will be fine.
[0072] Please refer to Figure 7 In the cross-sectional view of an electronic device shown, in other embodiments, the first connection portion 31 is a positioning hole, and the second connection portion 43 is a positioning post. Alternatively, the edge seal 3 includes multiple first connection portions 31, and the housing 4 includes multiple second connection portions 43. Some of the multiple first connection portions 31 are positioning posts, and another portion of the multiple first connection portions 31 are positioning holes. Accordingly, the multiple second connection portions 43 include positioning posts that correspond one-to-one with each positioning hole in the first connection portion 31, and positioning holes that correspond one-to-one with each positioning post in the first connection portion 31.
[0073] In a specific implementation, the cross section of the first connecting portion 31 perpendicular to its own axis and the cross section of the second connecting portion 43 perpendicular to its own axis may have the same shape or different shapes. The following description is based on the example that the cross section of the first connecting portion 31 perpendicular to its own axis and the cross section of the second connecting portion 43 perpendicular to its own axis have the same shape, and the first connecting portion 31 is a positioning column. For example: Figure 8a and Figure 8b As shown in FIG, the cross section of the first connecting portion 31 perpendicular to its own axis is rectangular, and the cross section of the second connecting portion 43 perpendicular to its own axis should also be rectangular. Since the shapes of the first connecting portion 31 and the second connecting portion 43 are compatible, the structure of the second connecting portion 43 is not illustrated here. Alternatively, Figure 8c As shown in FIG, the cross-section of the first connecting portion 31 perpendicular to its own axis is a triangle, and the cross-section of the second connecting portion 43 perpendicular to its own axis is also a triangle. Figure 8d As shown, the cross-section of the first connecting portion 31 perpendicular to its own axis is circular, and the cross-section of the second connecting portion 43 perpendicular to its own axis is also circular. Figure 8e As shown in FIG, the cross section of the first connecting portion 31 perpendicular to its own axis is elliptical, and the cross section of the second connecting portion 43 perpendicular to its own axis is also elliptical. Alternatively, as shown in FIG. Figure 8f As shown, the cross-section of the first connecting portion 31 perpendicular to its own axis is in the shape of an oblong circle, and the cross-section of the second connecting portion 43 perpendicular to its own axis is also in the shape of an oblong circle, and so on.
[0074] When the cross-section of the first connecting portion 31 perpendicular to its axis and the cross-section of the second connecting portion 43 perpendicular to its axis are rectangular, the torsion resistance is improved. When the cross-section of the first connecting portion 31 perpendicular to its axis and the cross-section of the second connecting portion 43 perpendicular to its axis are both triangular, while achieving the same connection strength, the cross-sectional area is smaller and the torsion resistance is also improved. When the cross-section of the first connecting portion 31 perpendicular to its axis and the cross-section of the second connecting portion 43 perpendicular to its axis are both circular, processing and assembly are easier, and tolerance requirements are reduced. When the cross-section of the first connecting portion 31 perpendicular to its axis and the cross-section of the second connecting portion 43 perpendicular to its axis are both elliptical, processing and assembly are easier, tolerance requirements are reduced, and torsion resistance is also improved. It should be noted that in some embodiments, the edge seal 3 includes multiple first connecting portions 31, and the cross-sectional shapes of these multiple first connecting portions 31 can be at least two of the following: rectangular, triangular, circular, elliptical, or oblong.
[0075] Figure 9a This is a schematic structural diagram of a combination of a light-transmitting cover plate, a screen laminate, and an edge seal in an electronic device provided in an embodiment of the present application. Figure 9b for Figure 9a Another angle of the structural diagram. Figure 9a and Figure 9b , the light-transmitting cover plate 1 is arranged on the light-emitting surface of the screen laminate 2, wherein, Figure 9b The dotted box in the figure illustrates the screen stack 2 located on the side of the transparent cover plate 1 facing the housing 4. The edge seal is attached to the surface of the transparent cover plate facing the screen stack, and the edge seal surrounds, covers, and adheres to the side of the screen stack. Specifically, the edge seal 3 has two long sides 32 and two short sides 33 arranged opposite each other. Both long sides 32 of the edge seal 3 are provided with at least one first connecting portion 31. Figure 9b In the illustrated embodiment, each of the two long sides 32 of the edge seal 3 is provided with three first connecting portions 31. The stress conditions on the long sides 32 are simpler than those on the short sides 33. Therefore, providing the first connecting portions 31 on the long sides 32 can simplify the force analysis of the electronic device while ensuring connection reliability in the thickness direction H of the electronic device. Obviously, the long sides 32 of the edge seal 3 are parallel or approximately parallel to the long sides 32 of the electronic device, and the short sides 33 of the edge seal 3 are parallel or approximately parallel to the short sides 33 of the electronic device. Of course, in specific implementations, the number of first connecting portions 31 on the two long sides 32 of the edge seal 3 may vary. In other embodiments, the first connecting portions 31 may also be provided on the short sides 33 of the edge seal 3; the specific circumstances will not be further described here.
[0076] In addition, by Figure 9bIt can be seen that the surface of the screen stack 2 facing away from the transparent cover 1 can be provided with devices such as a flexible circuit board 500, a driving chip 600 and a capacitor 700. The flexible circuit board 500, the driving chip 600 and the capacitor 700 are all electrically connected to the screen stack 2 so that the display module can realize the display function.
[0077] Figure 9c This is a schematic diagram of the structure of a housing, etc. in an electronic device provided in an embodiment of the present application. Figure 9c As shown, the housing 4 includes a middle frame 410, which includes a frame 41 and a carrier plate 42. The carrier plate 42 is provided with holes, and the edge of the carrier plate 42 is provided with a step T. The frame 41 is arranged around the edge of the carrier plate 42 and is fixedly connected to the carrier plate 42, and the frame 41 protrudes from the surface of the carrier plate 42 facing the transparent cover plate. Figure 9b The second connection parts 43 corresponding to each first connection part 31 in the embodiment.
[0078] Figure 10a This is a schematic diagram of the structure of a housing, etc. in an electronic device provided in an embodiment of the present application. Figure 10b for Figure 10a The enlarged view of point B, Figure 10c for Figure 10a The enlarged view of point C. Figure 10a 、 Figure 10b and Figure 10c As shown in the figure, in one specific implementation, each of the two long sides 32 of the edge banding 3 is provided with five positioning posts. The two positioning posts at the longitudinal ends of the edge banding 3 and the central positioning post have circular cross-sections perpendicular to their axes, while the remaining two positioning posts have oblong cross-sections perpendicular to their axes. The circular positioning posts serve as position limits in the length and width directions of the electronic device, while the oblong positioning posts provide anti-twist protection.
[0079] It is worth noting that, in some embodiments, Figure 10a As shown, the first connecting portions 31 on the two long sides 32 of the edge seal 3 are symmetrically distributed about the centerline a of the electronic device, facilitating assembly of the electronic device and also improving the connection strength between the assembly consisting of the light-transmitting cover 1, the screen laminate 2, and the edge seal 3 and the housing 4. Of course, the first connecting portions 31 on the two long sides 32 of the edge seal 3 can also be asymmetrically distributed about the centerline of the electronic device.
[0080] Figure 11a This is a partial cross-sectional view of an electronic device according to an embodiment of the present application. Figure 11aAs shown, in a specific implementation, the edge sealing member 3 is partially filled between the surface of the screen laminate 2 facing away from the light-transmitting cover plate 1 and the shell 4. For example, the edge sealing member 3 is partially filled between the surface of the screen laminate 2 facing away from the light-transmitting cover plate 1 and the carrier plate 42. The portion of the edge sealing member 3 filled between the surface of the screen laminate 2 facing away from the light-transmitting cover plate 1 and the shell 4 is adhered to the surface of the screen laminate 2 to improve the connection reliability between the edge sealing member 3 and the screen laminate 2, and at the same time, better protect the screen laminate 2. In this case, the orthographic projection of the first connecting portion 31 on the light-transmitting cover plate 1 can be located within the range of the orthographic projection of the screen laminate 2 on the light-transmitting cover plate 1, as shown in FIG. Figure 11a shown.
[0081] Figure 11b FIG. 1 is a partial cross-sectional view of another electronic device according to an embodiment of the present application. Figure 11b As shown, in some embodiments, the orthographic projection of the first connecting portion 31 on the transparent cover plate 1 does not overlap with the orthographic projection of the screen laminate 2 on the transparent cover plate 1. In this way, the stress of the entire device is directly transferred to the transparent cover plate 1 through the thickness direction H of the electronic device, avoiding the screen laminate 2 from being subjected to stress, thereby reducing the impact of the stress generated when the first connecting portion 31 and the second connecting portion 43 are connected on the screen laminate 2, which is beneficial to improving the yield rate in the electronic device manufacturing process. Of course, in other embodiments, the orthographic projection of the first connecting portion 31 on the transparent cover plate 1 may also partially overlap with the orthographic projection of the screen laminate 2 on the transparent cover plate 1. It should be understood that the orthographic projection of the first connecting portion 31 on the transparent cover plate 1 is the projection of the first connecting portion 31 obtained by taking one surface of the transparent cover plate 1 as the projection plane and making the projection line perpendicular to the surface of the transparent cover plate 1.
[0082] There are many ways to achieve the fixed connection between the positioning column and the positioning hole, which are described in detail below with reference to the accompanying drawings.
[0083] Figure 12 This is a partial cross-sectional view of an electronic device according to an embodiment of the present application. Figure 12 As shown, in one possible implementation, the first connection portion 31 includes a positioning post, and the second connection portion 43 includes a positioning hole. The positioning hole is a blind hole. The bottom surface of the blind hole or the surface of the positioning post facing the positioning hole is provided with a first adhesive layer 5. The bottom surface of the positioning hole and the surface of the positioning post facing the positioning hole are bonded together by the first adhesive layer 5 to achieve a fixed connection between the first connection portion 31 and the second connection portion 43 along the thickness direction H of the electronic device. The positioning post is inserted into the positioning hole and fixed by the adhesive layer, which simplifies the assembly of the electronic device and helps improve the assembly efficiency of the electronic device. It is not difficult to understand that the bottom surface of the blind hole is the surface of the blind hole away from the open end; the first adhesive layer 5 may also be filled between the circumference of the positioning post and the side wall of the blind hole.
[0084] Illustratively, the bottom surface of the positioning hole or the surface of the positioning post facing the positioning hole is affixed with adhesive, such as double-sided pressure-sensitive tape. The positioning post and the positioning hole are then pressed together and bonded. In other words, the adhesive serves as the first adhesive layer 5. In another specific implementation, the first adhesive layer 5 can be a dispensing layer. Illustratively, glue is applied to the bottom surface of the positioning hole or the surface of the positioning post facing the positioning hole. After the post and hole are assembled, the glue is cured and bonded. The glue can be either heat-curing or light-curing.

Figure 13 As shown, in some embodiments, the first connecting portion 31 includes a positioning post, the outer surface of which is provided with a snap-fitting portion 6.

The second connecting portion 43 includes a positioning hole provided in the housing 4, and the positioning hole is a through hole. The positioning post is inserted into the positioning hole, and the snap-fitting portion 6 is exposed in the positioning hole and snap-fits with the housing 4, thereby achieving a fixed connection between the first connecting portion 31 and the second connecting portion 43 along the thickness direction H of the electronic device.

The positioning post is inserted into the positioning hole, and the snap-fitting portion 6 is exposed in the positioning hole and snap-fits with the surface of the carrier plate 42 facing away from the transparent cover plate 1. This solution can also simplify the assembly of the electronic device, thereby improving assembly efficiency. Exemplarily, the snap-fitting portion 6 includes a snap-fitting boss or an arc-shaped protrusion. It is understood that the snap-fitting portion 6 is deformable to allow the snap-fitting portion 6 to pass through the positioning hole. The size of the clamping portion 6 exposed in the radial direction of the positioning post through the positioning hole can be set according to actual needs, as long as the clamping portion 6 can pass through the positioning hole and be clamped to the surface of the supporting plate 42 away from the transparent cover plate 1.
[0086] Please continue to refer to Figure 13 In one possible implementation, the radial dimension of the clamping portion 6 gradually decreases along the direction from the light-transmitting cover plate 1 toward the screen laminate 2, so that the clamping portion 6 can pass through the positioning hole on the carrier plate 42. It should be understood that the radial dimension of the clamping portion 6 refers to the direction passing through the axis of the positioning post and being perpendicular to the axis of the positioning post.

Each screw 7 is used to pass through the fixing through-hole 44 and fixedly connect to the positioning post. Each positioning post is fixed to the positioning hole corresponding to the positioning post by the screw 7, which increases the connection strength. Exemplarily, the axis of the positioning hole coincides with the axis of the fixing through-hole 44, and the screw 7 is driven into the positioning post along the axis of the positioning post.

[0090] Specifically, when a positioning column is set on the edge banding member 3 or the shell 4, in one possible implementation method, the elastic modulus of the positioning column is greater than or equal to 1.5 GPa, so as to achieve high-strength fit with the positioning hole through material optimization and specific shape design of the positioning column, thereby ensuring the connection reliability between the positioning column and the positioning hole.
