[0003] The present application relates to the technical field of electronic devices, and in particular to an electronic device. BACKGROUND

[0004] For electronic devices with display modules, high screen-to-body ratio of the display modules has always been a manifestation of competitiveness. It is not difficult to understand that under the same conditions, the smaller the black border width of the display module, the higher the screen-to-body ratio of the display module. The higher the screen-to-body ratio of the display module, the less the interference in the field of view of the user when using the electronic device, and the more conducive to providing the user with a good immersive use experience. Therefore, how to reduce the black border width of the display module of the electronic device is a problem that designers need to strive to solve. SUMMARY

The light-transmitting cover plate is fixed to the light-out surface of the screen stack, and the edge of the light-transmitting cover plate exceeds the edge of the screen stack. The edge sealing member is arranged between the light-transmitting cover plate and the housing, and the edge sealing member is at least bonded to the surface of the light-transmitting cover plate facing the screen stack and the side surface of the screen stack. The edge sealing member includes at least one first connecting part, and the housing includes at least one second connecting part. Any one of the first connecting parts is one of a positioning hole and a positioning column, and any one of the second connecting parts is the other of the positioning hole and the positioning column. The positioning hole is used to accommodate the positioning column, and the positioning column is used to extend into the positioning hole along the thickness direction of the electronic device and is fixedly connected with the positioning hole.

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.

[0013] In a possible embodiment, the radial dimension of the clamping part gradually decreases in a direction in which the light-transmitting cover plate points to the screen stack, so that the clamping part is more convenient to pass through the second connecting hole.

DETAILED DESCRIPTION

[0059] Embodiments of the present application provide an electronic device, which is a kind of electronic device with 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 notebook computer, a tablet computer, a vehicle-mounted device, augmented reality (AR) glasses, AR helmet, virtual reality (VR) glasses or VR helmet, etc. For the convenience of description, the electronic device is taken as a mobile phone as an example for detailed description.

[0060] FIG. 1 is an exploded view of an electronic device. As shown in FIG. 1, the electronic device generally includes a display module 100, a circuit board 200 and a housing 300, etc. The display module 100 includes a light-transmitting cover plate 110 and a screen stack 120, etc. The light-transmitting cover plate 110 and the screen stack 120 are adhered together by glue. 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. The light-transmitting cover plate 110 and the screen stack 120 can be adhered together by an optically clear adhesive (OCA). Exemplarily, the housing 300 can be an integrated structure as shown in FIG. 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. The display module 100 is arranged at the opening of the housing 300.

[0061] In some embodiments, as shown in FIG. 2a, a schematic diagram of a cross-sectional structure of an electronic device, the shell 300 is a split structure, including a middle frame 310 and a back cover 320 connected together. Among them, the back cover 320 is also called the battery cover. FIG. 2b is a partial enlarged view of FIG. 2a. In a specific implementation, the back cover 320 is arranged on one side of the middle frame 310, and the back cover 320 is fixedly connected with the middle frame 310. The light-transmitting cover plate 110 is arranged on the side of the middle frame 310 away from the back cover 320 and is fixed to the middle frame 310. The light-transmitting cover plate 110, the middle frame 310 and the back cover 320 can enclose an accommodation space, and the screen stack 120, the circuit board 200 and other electronic components are arranged in the accommodation space.

[0062] Among them, the display module 100 includes a display area and a non-display area, and 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 part from the edge of the display area of the display module 100 to the inner edge of the side wall of the shell 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 shell 300. For example, referring to FIG. 2c, a schematic diagram of a partial cross-sectional structure of an electronic device is shown. As shown in FIG. 2c, in the electronic device, the shell 300 includes a middle frame 310 and a back cover 320, the light-transmitting cover plate 110 is bonded to the middle frame 310 through the sealant 400, and the screen stack 120 is bonded to the middle frame 310 through the back adhesive. In order to ensure that the screen stack 120 can enter the middle frame 310 and that the screen stack 120 does not collide with the middle frame 310 during the process of entering the middle frame 310, a gap d needs to be reserved between the edge of the screen stack 120 and the inner side wall of the middle frame 310. The existence of the gap d further increases the width of the black border of the display module, which brings an undesirable experience to the user.

[0063] Based on this, the embodiment of the present application provides an electronic device, the display module of the electronic device has a smaller black border width, and the screen ratio of the display module is higher, which can bring a better user experience. In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be described in more detail below with reference to the drawings.

[0066] Fig. 3a is a perspective structural schematic diagram of an electronic device provided by the present application, and Fig. 3b is an exploded view of the electronic device shown in Fig. 3a. As shown in Figs. 3a and 3b, the electronic device provided by the present application comprises a light-transmitting cover plate 1, a screen stack 2, an edge sealing member 3 and a housing 4. Exemplarily, the light-transmitting cover plate 1 can be a glass cover plate. In the thickness direction H of the electronic device, the edge of the light-transmitting cover plate 1 is fixed to the housing 4, and a containing space is formed between the light-transmitting cover plate 1 and the housing 4. The light-transmitting cover plate 1 can be bonded together with the screen stack 2 through an optical adhesive layer, and the screen stack 2 is located on the surface of the light-transmitting cover plate 1 facing the housing 4, wherein the dashed box in Figs. 3a and 3b schematically shows the screen stack 2 located on the side of the light-transmitting cover plate 1 facing the housing 4. The light-transmitting cover plate 1 is fixed on the light-out surface of the screen stack 2, and the edge of the light-transmitting cover plate 1 exceeds the edge of the screen stack 2, that is, the area of the light-transmitting cover plate 1 is larger than the area of the screen stack 2, and the orthographic projection of the screen stack 2 on the surface of the light-transmitting cover plate 1 falls within the edge range of the light-transmitting cover plate 1 and has a certain distance from the edge of the surface of the light-transmitting cover plate 1, and the orthographic projection of the light-transmitting cover plate 1 on the screen stack 2 completely covers the screen stack 2. It is not difficult to understand that the orthographic projection of the screen stack 2 on the surface of the light-transmitting cover plate 1 refers to the projection of the screen stack 2 obtained by taking one surface of the light-transmitting cover plate 1 as the projection surface and making the projection line perpendicular to the surface of the light-transmitting cover plate 1. The edge sealing member 3 is arranged between the light-transmitting cover plate 1 and the housing 4, specifically, the edge sealing member 3 is bonded to the surface of the light-transmitting cover plate 1 facing the screen stack 2, and the edge sealing member 3 covers and is bonded to the side surface of the screen stack 2. That is, the screen stack 2 is fixed in the space surrounded by the light-transmitting cover plate 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 light-transmitting cover plate 1 facing the screen stack 2 and the side surface of the screen stack 2. Exemplarily, the edge sealing member 3 can be prepared by a glue-filling process or other processes. The housing 4 comprises a middle frame 410 and a back cover 420, and the middle frame 410 and the back cover 420 are arranged and fixedly connected in the thickness direction H of the electronic device. The middle frame 410 comprises a frame 41 and a bearing plate 42, the frame 41 surrounds the edge of the bearing plate 42 and is fixedly connected with the bearing plate 42, and the frame 41 protrudes from the two side surfaces of the bearing plate 42. The light-transmitting cover plate 1 and the screen stack 2 are arranged on the side of the bearing plate 42 away from the back cover 420. Exemplarily, 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 implementation, according to actual needs, holes, steps or the like can be formed on the bearing plate 42 to facilitate the arrangement of various elements in the housing 4.

[0067] In some embodiments, as shown in FIG. 3b, the edge member 3 comprises at least one first connecting part 31, the shell 4 comprises at least one second connecting part 43, any one of the first connecting part 31 is one of a positioning hole and a positioning column, any one of the second connecting part 43 is the other of the positioning hole and the positioning column, the positioning hole is used to accommodate the positioning column, the positioning column is used to extend into the positioning hole along the thickness direction H of the electronic device and is fixedly connected with the positioning hole, so as to connect the edge member 3 with the shell 4, and further realize the connection of the combination of the light-transmitting cover plate 1, the screen stack 2 and the edge member 3 with the shell 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 light-transmitting cover plate 1 and the screen stack 2.

[0068] In the electronic device provided by the embodiments of the present application, the light-transmitting cover plate 1 and the screen stack 2 are connected with the shell 4 through the edge member 3. In the processing process, the edge member 3 can be prepared on the light-transmitting cover plate 1 and the screen stack 2 first, and then the combination of the light-transmitting cover plate 1, the screen stack 2 and the edge member 3 is fixedly connected with the shell 4. The edge member 3 is bonded to the side surface of the screen stack 2, which can protect the screen stack 2 during the process of loading the screen stack into the shell, so there is no need to worry about the screen stack being scratched by the shell. In addition, the edge member 3 can be a flexible member, so there is no need to reserve a gap between the edge member 3 and the screen stack 2. In the present scheme, the gap between the edge member 3 and the screen stack 2 is cancelled, so the black border width of the display module 100 can be reduced. Furthermore, at least one first connecting part 31 is arranged on the surface of the edge member 3 facing the shell 4, and a second connecting part 43 matched with the first connecting part 31 is arranged on the shell 4, the combination of the light-transmitting cover plate 1, the screen stack 2 and the edge member 3 is fixedly connected with the shell 4 through the connection between the first connecting part 31 and the second connecting part 43, the connection structure of the above combination and the shell 4 in the thickness direction H of the electronic device is increased, the connection strength of the combination and the shell 4 in the thickness direction H of the electronic device is improved, so that the ability of the edge member 3 to resist side impact can be reduced, and thus the width of the edge member 3 can be appropriately reduced, thereby facilitating the further reduction of the black border width of the display module. Therefore, compared with the electronic device using the glue filling scheme, the electronic device provided by the present application can significantly reduce the black border of the display module 100 and improve the screen-to-body ratio of the display module. In some embodiments, the black border width of the display module 100 of the electronic device using the glue filling scheme is 0.8-1 mm, and in the electronic device provided by the present application, the black border width of the display module 100 is 0.2-0.25 mm.

[0069] Fig. 4 is a partial cross-sectional view of a housing 4 in an electronic device according to an embodiment of the present application. As shown in Fig. 4, when the housing 4 is specifically provided, at least one second connecting part 43 can be formed on the bearing plate 42, or at least one second connecting part 43 can be formed on the back cover 420, wherein when the second connecting part 43 is formed on the back cover 420, the bearing plate 42 is provided with a through hole for the second connecting part 43 to pass through.

[0070] Fig. 5a is a front view of an electronic device according to an embodiment of the present application, and Fig. 5b is a cross-sectional view of A-A in Fig. 5a. As shown in Figs. 5a and 5b, by way of example, the edge member 3 is fixed on the surface of the light-transmitting cover plate 1 facing the housing 4 in the same layer as the screen stack 2, and the edge member 3 is located between the circumferential side surface of the screen stack 2 and the middle frame 41, and the edge member 3 is connected with the circumferential side surface of the screen stack 2. The first connecting part 31 is formed as a positioning column protruding towards the housing 4 along the thickness direction H of the electronic device, and the second connecting part 43 is formed as a positioning hole recessed from the surface of the bearing plate 42 facing the light-transmitting cover plate 1 to the surface of the bearing plate 42 facing away from the light-transmitting cover plate 1, and the first connecting part 31 is inserted into the second connecting part 43 and fixedly connected, thereby realizing the connection and fixation of the edge member 3 and the housing 4. Along the thickness direction H, the orthogonal projection of the screen stack 2 on the light-transmitting cover plate 1 and the orthogonal projection of the first connecting part 31 on the light-transmitting cover plate 1 do not overlap. Here, the second connecting part 32 is a blind hole. The first connecting part 31 and the second connecting part 32 can be connected and fixed by means of gluing, interference fit, etc.

[0071] In the embodiment shown in Fig. 5b, the axes m of the positioning column and the positioning hole both extend along the thickness direction H of the electronic device, and the first connecting part 31 and the second connecting part 43 can be connected and fixed along the thickness direction H of the electronic device. In the embodiments of the present application, the positioning column is used to extend into the positioning hole along the thickness direction H of the electronic device and to be fixedly connected with the positioning hole, which should be understood in a broad sense, that is, the axis direction of the positioning column and the positioning hole is not limited to the thickness direction H of the electronic device, as long as the distance between the end of the positioning column away from the light-transmitting cover plate and the light-transmitting cover plate changes in the thickness direction H of the electronic device during the process of inserting the positioning column into the positioning hole. By way of example, in the present solution, the first connecting part 31 is the positioning column, and the second connecting part 43 is the positioning hole. Here, the screen stack 2 can include, in sequence from the direction away from the light-transmitting cover plate, an optically clear adhesive (OCA), a polarizer (POL), a display panel, a back film (BF), an adhesive layer (for example, a silicone gel layer), and a copper layer.

[0072] Exemplarily, as shown in FIG. 6a, in some embodiments, the axis m of the positioning post as the first connecting part 31 and the positioning hole as the second connecting part 43 are both at an angle with the thickness direction H of the electronic device. In this case, when the first connecting part 31 and the second connecting part 43 are connected and fixed, the positioning post can be deformed to some extent so that the positioning post can be smoothly inserted into the positioning hole. As shown in FIG. 6b, in other embodiments, the axis m of the positioning post is in a zigzag shape and one segment of the axis m extends along the thickness direction H of the electronic device, and the like. 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 with the positioning hole, this place will not be listed one by one.

[0073] As can be seen from the above embodiments, the positioning hole can be a blind hole, as shown in FIG. 6a; the positioning hole can also be a through hole, as shown in FIG. 6b. As long as the positioning post can be inserted into the corresponding positioning hole.

[0074] Please refer to the cross-sectional view of an electronic device shown in FIG. 7, in other embodiments, the first connecting part 31 is a positioning hole and the second connecting part 43 is a positioning post. Alternatively, the edge sealing member 3 includes a plurality of first connecting parts 31, the shell 4 includes a plurality of second connecting parts 43, a part of the plurality of first connecting parts 31 are positioning posts, another part of the plurality of first connecting parts 31 are positioning holes, and correspondingly, the plurality of second connecting parts 43 include positioning posts corresponding to each positioning hole in the first connecting parts 31 and positioning holes corresponding to each positioning post in the first connecting parts 31.

[0075] In specific implementation, the cross section of the first connecting portion 31 perpendicular to the axis thereof can be the same as or different from the cross section of the second connecting portion 43 perpendicular to the axis thereof. Hereinafter, the first connecting portion 31 is taken as an example, which is a positioning column, and the cross section of the first connecting portion 31 perpendicular to the axis thereof is the same as the cross section of the second connecting portion 43 perpendicular to the axis thereof. For example, as shown in FIGS. 8a and 8b, the cross section of the first connecting portion 31 perpendicular to the axis thereof is a rectangle, and the cross section of the second connecting portion 43 perpendicular to the axis thereof is also a rectangle. Since the shapes of the first connecting portion 31 and the second connecting portion 43 are matched, the structure of the second connecting portion 43 is not shown here. Alternatively, as shown in FIG. 8c, the cross section of the first connecting portion 31 perpendicular to the axis thereof is a triangle, and the cross section of the second connecting portion 43 perpendicular to the axis thereof is also a triangle. Alternatively, as shown in FIG. 8d, the cross section of the first connecting portion 31 perpendicular to the axis thereof is a circle, and the cross section of the second connecting portion 43 perpendicular to the axis thereof is also a circle. Alternatively, as shown in FIG. 8e, the cross section of the first connecting portion 31 perpendicular to the axis thereof is an ellipse, and the cross section of the second connecting portion 43 perpendicular to the axis thereof is also an ellipse. Alternatively, as shown in FIG. 8f, the cross section of the first connecting portion 31 perpendicular to the axis thereof is an oblong, and the cross section of the second connecting portion 43 perpendicular to the axis thereof is also an oblong.

[0076] When the cross section of the first connecting portion 31 perpendicular to the axis thereof is a rectangle, the torsion resistance is good. When the cross section of the first connecting portion 31 perpendicular to the axis thereof and the cross section of the second connecting portion 43 perpendicular to the axis thereof are both triangles, the cross section area is smaller, and the torsion resistance is also good under the condition of the same connection strength. When the cross section of the first connecting portion 31 perpendicular to the axis thereof and the cross section of the second connecting portion 43 perpendicular to the axis thereof are both circles, the processing and assembly are easy, and the tolerance requirement is small. When the cross section of the first connecting portion 31 perpendicular to the axis thereof and the cross section of the second connecting portion 43 perpendicular to the axis thereof are both ellipses, the processing and assembly are easy, the tolerance requirement is small, and the torsion resistance is also good. It should be noted that, in some embodiments, the edge sealing member 3 includes a plurality of first connecting portions 31, and the cross section shape of the plurality of first connecting portions 31 can be at least two of a rectangle, a triangle, a circle, an ellipse, and an oblong.

Referring to Figs. 9a and 9b, the light-transmitting cover plate 1 is arranged on the light-exit surface of the screen stack 2. In Fig. 9b, the dashed box schematically shows the screen stack 2 on the side of the light-transmitting cover plate 1 facing the housing 4. The sealing member is attached to the surface of the light-transmitting cover plate facing the screen stack, and the sealing member surrounds the screen stack and is attached to the side surface of the screen stack. Specifically, the sealing member 3 has two opposite long edges 32 and two opposite short edges 33, and each of the two long edges 32 of the sealing member 3 is provided with at least one first connecting portion 31. In the scheme shown in Fig. 9b, each of the two long edges 32 of the sealing member 3 is provided with three first connecting portions 31. The stress condition of the long edge 32 is simpler than that of the short edge 33, so that the arrangement of the first connecting portion 31 on the long edge 32 can simplify the stress analysis of the electronic device while ensuring the reliability of the connection in the thickness direction H of the electronic device. Obviously, the long edge 32 of the sealing member 3 is parallel or substantially parallel to the long edge 32 of the electronic device, and the short edge 33 of the sealing member 3 is parallel or substantially parallel to the short edge 33 of the electronic device. Of course, the number of the first connecting portions 31 on the two long edges 32 of the sealing member 3 can be different in specific implementation. In other embodiments, the first connecting portion 31 can also be arranged on the short edge 33 of the sealing member 3, and the specific case will not be described here.

[0080] Fig. 10a is a structural schematic diagram of a housing or the like in an electronic device according to an embodiment of the present application, Fig. 10b is an enlarged view of B in Fig. 10a, and Fig. 10c is an enlarged view of C in Fig. 10a. As shown in Figs. 10a, 10b and 10c, in one specific implementation, the two long edges 32 of the edge member 3 are each provided with five positioning columns, wherein the two positioning columns at the two ends in the length direction of the edge member 3 and the one positioning column in the middle are each circular in cross section perpendicular to the axis thereof, and the other two positioning columns are each oblong in cross section perpendicular to the axis thereof. The positioning columns circular in cross section serve to limit the position of the electronic device in the length direction and the width direction, and the positioning columns oblong in cross section serve to resist torsion.

[0081] It is worth noting that, in some embodiments, as shown in Fig. 10a, the first connecting portions 31 on the two long edges 32 of the edge member 3 are symmetrically distributed about the center line a of the electronic device, so as to facilitate the assembly of the electronic device, and also to facilitate the improvement of the connecting strength between the combination of the light-transmitting cover plate 1, the screen stack 2 and the edge member 3 and the housing 4. Of course, the first connecting portions 31 on the two long edges 32 of the edge member 3 can also be asymmetrically distributed about the center line of the electronic device.

[0082] Fig. 11a is a partial view of a cross-sectional view of an electronic device according to an embodiment of the present application. As shown in Fig. 11a, in one specific implementation, the edge member 3 is partially filled between the surface of the screen stack 2 away from the light-transmitting cover plate 1 and the housing 4, for example, the edge member 3 is partially filled between the surface of the screen stack 2 away from the light-transmitting cover plate 1 and the bearing plate 42. The portion of the edge member 3 filled between the surface of the screen stack 2 away from the light-transmitting cover plate 1 and the housing 4 is adhered to the surface of the screen stack 2, so as to improve the connecting reliability between the edge member 3 and the screen stack 2, and better protect the screen stack 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 orthographic projection of the screen stack 2 on the light-transmitting cover plate 1, as shown in Fig. 11a.

[0083] Fig. 11b is a partial view of a cross section of another electronic device according to an embodiment of the present application. As shown in Fig. 11b, in some embodiments, the orthographic projection of the first connecting part 31 on the light-transmissive cover plate 1 does not overlap with the orthographic projection of the screen stack 2 on the light-transmissive cover plate 1, so that the stress of the whole machine can be directly transmitted to the light-transmissive cover plate 1 in the thickness direction H of the electronic device, and the screen stack 2 is not stressed, thereby reducing the influence of the stress generated when the first connecting part 31 is connected with the second connecting part 43 on the screen stack 2, and improving the yield rate during the manufacturing of the electronic device. Of course, in other embodiments, the orthographic projection of the first connecting part 31 on the light-transmissive cover plate 1 can partially overlap with the orthographic projection of the screen stack 2 on the light-transmissive cover plate 1. It should be understood that the orthographic projection of the first connecting part 31 on the light-transmissive cover plate 1 is the projection of the first connecting part 31 obtained by taking one surface of the light-transmissive cover plate 1 as the projection surface and making the projection line perpendicular to the surface.

[0084] There are various ways to achieve the fixed connection between the positioning column and the positioning hole, which will be described in detail below with reference to the accompanying drawings.

[0085] Fig. 12 is a partial view of a cross section of an electronic device according to an embodiment of the present application. As shown in Fig. 12, in one possible implementation, the first connecting part 31 includes a positioning column, the second connecting part 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 column facing the positioning hole is provided with a first adhesive layer 5, and the bottom surface of the positioning hole and the surface of the positioning column facing the positioning hole are adhered through the first adhesive layer 5 to achieve the fixed connection of the first connecting part 31 and the second connecting part 43 in the thickness direction H of the electronic device. The positioning column is inserted into the positioning hole and adhered and fixed through the adhesive layer, so that the assembly of the electronic device is simplified, and the assembly efficiency of the electronic device is improved. It should be understood that the bottom surface of the blind hole is the surface of the blind hole away from the open end; and the first adhesive layer 5 can also be filled between the peripheral surface of the positioning column and the side wall of the blind hole.

[0086] For example, the bottom surface of the positioning hole or the surface of the positioning column facing the positioning hole is pasted with a back adhesive, such as a double-sided pressure-sensitive adhesive tape, and the positioning column and the positioning hole are assembled and pressed to be adhered. That is, the back adhesive is used as the first adhesive layer 5. In another specific implementation, the first adhesive layer 5 can be a dispensing layer, for example, the bottom surface of the positioning hole or the surface of the positioning column facing the positioning hole is dispensed with glue, and the positioning column and the positioning hole are assembled and adhered after the glue is cured. The glue can be a heat-cured glue or a light-cured glue.

The positioning column is inserted into the positioning hole, and the clamping part 6 is exposed from the positioning hole and clamped with the surface of the bearing plate 42 away from the light-transmitting cover plate 1. This scheme can also simplify the assembly of the electronic device, thereby improving the assembly efficiency of the electronic device. For example, the clamping part 6 comprises a clamping boss or an arc-shaped protruding part. It is understood that the clamping part 6 can be deformed so that the clamping part 6 can pass through the positioning hole. The size of the clamping part 6 exposed from the positioning hole along the radial direction of the positioning column can be set according to actual needs, as long as the clamping part 6 can pass through the positioning hole and be clamped with the surface of the bearing plate 42 away from the light-transmitting cover plate 1.

[0088] Please continue to refer to Fig. 13. In a possible implementation, the radial size of the clamping part 6 gradually decreases in the direction of the light-transmitting cover plate 1 pointing to the screen stack 2, so as to facilitate the clamping part 6 to pass through the positioning hole on the bearing plate 42. It should be understood that the radial direction of the clamping part 6 refers to the direction perpendicular to the axis of the positioning column.

[0092] Specifically, when the positioning column is arranged on the edge member 3 or the housing 4, in one possible implementation, the elastic modulus of the positioning column is greater than or equal to 1.5 GPa, so that the positioning column and the positioning hole are matched in high strength by the material optimization and the specific shape design of the positioning column, and the connection reliability between the positioning column and the positioning hole is ensured.
