Description

Screen assembly and electronic device

[0001] The present application claims priority to the Chinese Patent Application No. 202410729705.0, filed on June 5, 2024, and entitled "Screen assembly and electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of electronic products, and in particular to a screen assembly and an electronic device. BACKGROUND

[0003] The decoration piece of the camera module is arranged on the screen. When the electronic device falls or collides, the decoration piece of the camera module will extrude the screen, causing black spots or even cracks on the screen, and affecting the display function of the screen. SUMMARY

[0004] Embodiments of the present application provide a screen assembly and an electronic device, which are used to solve the problem of how to avoid the decoration piece of the camera module extruding the screen to cause the display function of the screen to fail.

[0005] To achieve the above-mentioned purpose, embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, the present application provides a screen assembly, which comprises a screen, a first decoration piece and a second decoration piece. The screen comprises a display surface and a non-display surface facing away from each other, and the screen further comprises a functional device hole penetrating through the display surface and the non-display surface, the functional device hole having a first opening located on the display surface and a second opening located on the non-display surface.

[0007] The first decoration piece is located on the side facing the display surface and is fixed to the display surface. The first decoration piece comprises a first part, which is annular and surrounds a first through hole. The first through hole is arranged opposite to the functional device hole. In this way, the first decoration piece does not occupy the internal space of the screen assembly, where the internal space refers to the space between the display surface and the non-display surface of the screen. The first decoration piece is located outside the screen assembly, and the screen assembly does not need to reserve internal space for the first decoration piece. The thickness of the screen assembly can be designed to be thinner.

[0008] The second decoration piece comprises a fixed part and a connecting part. The fixed part is fixed to the non-display surface, and the fixed part comprises a fixed segment. The connecting part is located in the functional device hole and is connected between the fixed segment and the first part.

[0009] In this way, the first decoration piece serves as an appearance piece of the screen assembly, and when the screen assembly falls or collides, the first decoration piece is easily impacted by stress. Compared with the screen assembly including only the first decoration piece, the stress borne by the first decoration piece is entirely transmitted to the screen. The screen assembly further includes a second decoration piece, and the second decoration piece supports the first decoration piece together with the screen. When the first decoration piece is impacted by stress, the stress borne by the first decoration piece is first transmitted to the screen and the connecting portion, and then transmitted to the fixing portion through the connecting portion.

[0010] Therefore, the stress borne by the first decoration piece can be dispersed to the screen and the second decoration piece, effectively dispersing and balancing the stress, avoiding the stress borne by the first decoration piece from being concentrated on the screen, and thereby reducing the risk of the screen being damaged by stress to appear black spots or even being broken, and improving the stability of the overall structure of the screen assembly.

[0011] In a possible implementation manner of the first aspect, the screen assembly further includes a first adhesive portion connected between the first portion and the connecting portion. In this way, the stability of the connection between the structural pieces in the screen assembly is improved. First, the first adhesive portion can be uniformly arranged between the first portion and the connecting portion, so that the first portion and the connecting portion are tightly bonded. Compared with threaded connection, the bonding mode can more uniformly distribute the load, reducing the stress concentration problem of the connection force between the first decoration piece and the second decoration piece, thereby effectively avoiding damage to the screen due to uneven stress.

[0012] Secondly, the first adhesive portion has better sealing performance. The first adhesive portion can seal the gap between the first decoration piece and the second decoration piece, avoiding moisture, dust and other small particles from entering the screen assembly through the gap between the first decoration piece and the second decoration piece, and protecting the internal electronic components of the screen assembly from corrosion and pollution. In turn, the service life of the electronic device is improved, and the overall performance of the electronic device is improved.

[0013] Furthermore, the first decoration piece and the second decoration piece are connected by bonding, which can simplify the assembly process of the first decoration piece and the second decoration piece, and reduce the production cost. Compared with threaded connection, the first decoration piece and the second decoration piece do not need to be provided with threaded holes matched with threaded parts, thereby also ensuring the structural strength of the first decoration piece and the second decoration piece.

[0014] In a possible implementation manner of the first aspect, the screen assembly further includes a second adhesive portion connected between the first decoration piece and the display surface. The display surface includes a first region and a second region surrounding the first region, and the first decoration piece has an intersection with the first region in orthographic projection on the screen. The dynamic friction coefficient of the first region is greater than that of the second region.

[0015] The second bonding part has better sealing performance, and can seal the gap between the first decorative part and the screen, so as to prevent small particles such as water and dust from entering the screen assembly through the gap between the first decorative part and the screen, and protect the internal electronic components of the screen assembly from corrosion and pollution. In turn, the service life of the electronic device is improved, and the overall performance of the electronic device is improved.

[0016] Based on the above-mentioned connection mode of the first decorative part and the display surface by the second bonding part, the first decorative part is prone to slipping relative to the display surface. Therefore, the dynamic friction coefficient of the first area is increased, and the friction between the first decorative part and the screen is increased during the pressure maintaining process of the bonding. The first decorative part is prevented from slipping relative to the screen, and the concentricity of the functional device and the first through hole is ensured, and the shooting quality of the camera module is also ensured.

[0017] In a possible implementation manner of the first aspect, the dynamic friction coefficient of the first area is greater than or equal to 0.1. In this way, the roughness of the first area is relatively large, and the first decorative part can be more effectively prevented from slipping relative to the screen, and the concentricity of the functional device and the first through hole is ensured.

[0018] In a possible implementation manner of the first aspect, the screen includes a cover plate and a friction-increasing layer. The cover plate has a first surface, and the friction-increasing layer is arranged on the first surface. A side surface of the friction-increasing layer opposite to the first surface defines the first area, and an area of the first surface located outside the friction-increasing layer is the second area. In this way, the roughness of the first area is increased by arranging the friction-increasing layer, and the arrangement of the friction-increasing layer is simple and convenient to operate. In addition, the friction-increasing layer can prevent the first decorative part from slipping relative to the screen, and the concentricity of the functional device and the first through hole is ensured, and the shooting quality of the camera module is also ensured.

[0019] In a possible implementation manner of the first aspect, the friction-increasing layer is an ink layer. First, the first ink layer can increase the roughness of the first area, and in turn prevent the first decorative part from slipping relative to the screen during the pressure maintaining process. Second, the first ink layer can improve the adhesion between the second bonding part and the first area, so as to improve the bonding force between the first decorative part and the screen. Finally, the first ink layer can shield the inside of the screen assembly, so as to prevent the user from observing the structure inside the screen assembly from the outside, and play a role in hiding the ugliness, so as to improve the aesthetic appearance of the screen assembly and the electronic device.

[0020] Generally, the ink layer for shielding the inside of the screen assembly is usually arranged between the cover plate and the display panel, and the first ink layer in the embodiment can shield the inside of the screen assembly while improving the dynamic friction coefficient of the first area. Therefore, the screen assembly can omit the ink layer arranged between the cover plate and the display panel, so that the first ink layer does not occupy the space inside the electronic device, thereby improving the utilization rate of the space inside the electronic device.

[0021] In a possible implementation of the first aspect, the screen includes a cover plate. The cover plate has a first surface, and the first surface has a first area and a second area, and the first area has a concave-convex structure. The first area improves the roughness through the concave-convex area, which can avoid the first decorative piece from slipping relative to the screen, thereby ensuring the concentricity of the functional device and the first through hole and ensuring the shooting quality of the camera module. In addition, the concave-convex structure can increase the bonding area of the second bonding part and the first area, thereby improving the bonding force between the first decorative piece and the screen and improving the stability of the screen assembly.

[0022] In a possible implementation of the first aspect, the first decorative piece includes a second surface facing the display surface, and the dynamic friction coefficient of the second surface is greater than or equal to the dynamic friction coefficient of the first area. In this way, the adhesion of the second bonding part and the first decorative piece is increased, which can avoid the first decorative piece from slipping relative to the screen, thereby ensuring the concentricity of the functional device and the first through hole and ensuring the shooting quality of the camera module.

[0023] In a possible implementation of the first aspect, the connecting part includes a third surface facing the first decorative piece, and the dynamic friction coefficient of the third surface is greater than or equal to the dynamic friction coefficient of the first area. In this way, the roughness of the third surface is relatively large, which can increase the friction between the first decorative piece and the second decorative piece, thereby further avoiding the first decorative piece from slipping relative to the screen, thereby ensuring the concentricity of the functional device and the first through hole and ensuring the shooting quality of the camera module.

[0024] In some embodiments, the third surface can improve the dynamic friction coefficient by arranging an ink layer, which is defined as a second ink layer in the embodiment. In this way, first, the second ink layer can improve the roughness of the third surface, increase the friction between the first decorative piece and the second decorative piece, and thereby avoid the first decorative piece from slipping relative to the screen during the pressure maintaining process. Second, the second ink layer can improve the adhesion of the first decorative piece and the second decorative piece to improve the bonding force of the first decorative piece and the second decorative piece. Finally, the second ink layer can shield the inside of the screen assembly, avoid the user from observing the structure inside the screen assembly from the outside, play a shielding role, and improve the aesthetics of the screen assembly and the electronic device.

[0025] In a possible implementation manner of the first aspect, the first decoration member has a first groove with an opening facing the connecting portion, and at least part of the first adhesive portion is accommodated in the first groove. In this way, the area of the adhesion between the first adhesive portion and the first portion is increased, and the connection strength between the first decoration member and the second decoration member is further increased, and the stability of the screen assembly is further improved.

[0026] In a possible implementation manner of the first aspect, the second decoration member is an integral molding. In this way, the adhesion between the second decoration member and the screen and the adhesion between the second decoration member and the first decoration member can be completed in the same process, and the assembly efficiency of the screen assembly is improved. In addition, the fixing portion and the connecting portion are an integral structure, and the stability of the second decoration member in dispersing the stress borne by the first decoration member is improved, and the stability of the screen assembly is further improved.

[0027] In a possible implementation manner of the first aspect, a side surface of the first decoration member opposite to the screen has an accommodation groove, and the first through hole is located at a groove bottom wall of the accommodation groove. The screen assembly further includes a light-transmitting plate fixed in the accommodation groove and covering the first through hole. In this way, the light-transmitting plate can prevent moisture and dust from entering the inside of the camera module, avoid damage to the camera module, and ensure the performance of the camera module.

[0028] In a possible implementation manner of the first aspect, the screen further includes a cover plate, a display panel and a buffer layer which are sequentially stacked, the first decoration member is fixed to the cover plate, and the fixing portion is fixed to the buffer layer. In this way, the first decoration member, the second decoration member and the screen form a sandwich structure, and the stability of the screen assembly is improved. After the adhesion of the components in the screen assembly is completed, the screen assembly is assembled to the first housing, and the assembly efficiency of the electronic device is improved. When the assembly of the screen assembly and the assembly of the screen assembly and the electronic device are not in the same production line, the structural members in the screen assembly are connected to each other, and the transfer of the screen assembly is facilitated. In addition, the screen assembly can be sold as a separate product, and the first decoration member, the second decoration member and the screen are connected to each other, and the transportation and sale of the screen assembly are facilitated.

[0029] In a possible implementation manner of the first aspect, the cover plate has a first surface and a fourth surface opposite to each other, and the fourth surface faces the display panel. At least part of the first adhesive portion is located in the functional device hole, and the first adhesive portion is located on a side of the fourth surface facing the first surface. In this way, the volume of the first adhesive portion is increased, and the adhesion strength between the first decoration member and the second decoration member is improved. In addition, when the screen assembly falls or collides, even if the second decoration member is slightly slipped relative to the first decoration member by a small distance, the second decoration member will only be extruded against the cover plate, and the second decoration member will not be extruded against the display panel, and the display function of the screen assembly in the collision scenario is also protected, and the display function of the screen assembly is prevented from being invalid.

[0030] In a possible implementation manner of the first aspect, the screen assembly further includes a third bonding part connected between the buffer layer and the fixing part. In this way, the first decorative part, the second decorative part and the screen form a sandwich structure, and the stability of the screen assembly is improved. After the bonding of the parts in the screen assembly is completed, the parts are assembled together to the first shell, and the assembly efficiency of the electronic device is improved. When the assembly of the screen assembly and the assembly of the screen assembly and the electronic device are not in the same production line, the structural parts in the screen assembly are connected to each other, and the transfer of the screen assembly is facilitated. In addition, the screen assembly can be sold as a separate product, and the first decorative part, the second decorative part and the screen are connected to each other, and the transportation and sale of the screen assembly are facilitated.

[0031] In a possible implementation manner of the first aspect, the connecting part is in a cylindrical shape. In this way, the second decorative part is formed by the cylindrical connecting part, and an end of the connecting part away from the fixing part surrounds a periphery of the first through hole and is connected to the first part. The cylindrical connecting part has a stable structure, good load bearing capacity and good stress impact resistance. When the electronic device falls or collides, the stress borne by the first decorative part is uniformly transmitted to the connecting part through the first part, and the cylindrical connecting part can uniformly disperse the stress borne by the first decorative part, reduce stress concentration, and improve the stability of the second decorative part. In addition, the cylindrical connecting part can disperse more stress to reduce the stress borne by the screen, thereby avoiding the problems of screen black spots and screen breakage caused by stress concentration of the screen, and improving the stability of the overall structure of the screen assembly.

[0032] In a possible implementation manner of the first aspect, the fixing part is in an annular sheet shape. In this way, the stress borne by the first decorative part is uniformly transmitted to the fixing part through the connecting part, and part of the stress borne by the first decorative part is uniformly dispersed on the fixing part. The second decorative part is formed by the connecting part and the fixing part, which avoids stress concentration of the stress borne by the first decorative part on the screen, avoids stress concentration of the stress borne by the first decorative part on the connecting part, and avoids stress concentration of the stress borne by the first decorative part on the fixing part, and improves the stability of the overall structure of the screen assembly.

[0033] In a possible implementation manner of the first aspect, the outer peripheral edge of the fixing portion has an avoiding gap. The side of the non-display surface of the screen assembly further comprises other structural members arranged on the side of the non-display surface, the screen has a first area opposite to the other structural members, and the fixing portion is arranged with the avoiding gap for accommodating the other structural members at the first area. In this way, a larger internal space does not need to be separately avoided for the arrangement of the fixing portion in the electronic device, and the fixing portion can be arranged in the gap between adjacent structural members in the electronic device. That is, the fixing portion can extend to the area in the electronic device with the gap space, so as to expand the support area of the fixing portion, and further improve the support effect of the second decorative member on the first decorative member, so as to avoid stress concentration of the first decorative member on the screen.

[0034] In a second aspect, the application further provides an electronic device, which comprises a shell assembly and a screen assembly, and the screen assembly is the screen assembly in the above description, and the screen assembly is fixed to the shell assembly.

[0035] The technical effects brought by any implementation manner of the second aspect can refer to the technical effects brought by different implementation manners of the first aspect, which will not be repeated here.

[0036] In a possible implementation manner of the second aspect, the shell assembly comprises a first shell, a second shell and a hinge mechanism, and the first shell and the second shell are rotationally connected to opposite sides of the hinge mechanism. The electronic device further comprises a flexible screen supported on the first shell, the hinge mechanism and the second shell. The screen assembly is supported on the side of the first shell away from the flexible screen.

[0037] In a possible implementation manner of the second aspect, the first shell is provided with a first structural member, and the first structural member is in contact with the surface of the fixing portion away from the screen. In this way, when the electronic device falls or collides, the stress received by the first decorative member is dispersed to the screen and the second decorative member, the second decorative member is in contact with the first structural member, and the stress received by the first decorative member is transmitted to the first structural member through the second decorative member. The first structural member provides a certain support effect for the first decorative member through the second decorative member, so that the first decorative member remains on the display surface of the screen, and the problem that the screen is pressed out of black spots or even broken when the first decorative member is stressed is avoided.

[0089] Please continue to refer to FIG. 4, the camera module 30 is used for shooting photos / videos. The camera module 30 is fixed in the internal accommodation space of the electronic device 100. When the camera module 30 is used as a front camera module, the camera module 30 can be fixed on the surface of the middle plate facing the flexible screen 11 by means of threaded connection, clamping, welding, etc.

[0090] When the camera module 30 is used as a rear camera module, the camera module 30 can be fixed on the surface of the main circuit board facing the first back cover 212 by means of threaded connection, clamping, welding, etc. In still other embodiments, the camera module 30 can be fixed on the surface of the middle plate facing the first back cover 212 by means of threaded connection, clamping, welding, etc. Alternatively, when the electronic device 100 does not include a middle plate, the camera module 30 can be fixed on the surface of the flexible screen 11 facing the first back cover 212. The camera module 30 is electrically connected to the main circuit board to facilitate the introduction of electric quantity and control signals to the camera module 30. The embodiments of the present application take the camera module 30 as a rear camera module as an example for description.

[0091] Please refer to FIG. 5, which is a bottom view of the first shell 21 shown in FIG. 4. The first back cover 212 has a functional device hole 121 at a position corresponding to the camera module 30, the functional device hole 121 is used for installing the camera module 30, and the light used for imaging by the camera module 30 enters the camera module 30 through the functional device hole 121. Moreover, at least part of the first back cover 212 can be replaced by the screen 12.

[0092] In some embodiments, part of the first back cover 212 is replaced by the screen 12, that is, the first back cover 212 is provided with a mounting port for installing the screen 12, the screen 12 is arranged in the mounting port, the first back cover 212 is connected to the screen 12, and the first back cover 212, the screen 12 and the first middle frame 211 together enclose the first accommodation cavity C1. As shown in FIG. 5, the screen 12 is arranged on one side of the functional device hole 121. In some embodiments, the screen 12 and the functional device hole 121 are arranged along the length direction of the electronic device 100, that is, the X-axis direction shown in FIG. 5. As shown in FIG. 6, which is a bottom view of the first shell 21 in another embodiment provided by the present application, in other embodiments, the screen 12 and the functional device hole 121 are arranged along the width direction of the electronic device 100, that is, the Y-axis direction shown in FIG. 6.

[0093] Since the functional device hole 121 needs a certain installation space, the screen 12 needs to avoid the installation space of the functional device hole 121. In this way, the display area of the screen 12 is small, which does not meet the user's demand for a large screen.

[0094] To meet the user's demand for large screens, please refer to FIG. 7, which is a bottom view of the first housing 21 in another embodiment provided by the present application. In some embodiments, the first back cover 212 is replaced entirely by the screen 12, and a first accommodating cavity C1 is formed between the first middle frame 211 and the screen 12. In this way, the functional device hole 121 is directly arranged on the screen 12, and the screen 12 does not need to avoid the space of the first back cover 212 required for arranging the functional device hole 121. The first back cover 212 can be replaced entirely by the screen 12 to improve the display area of the screen 12 and facilitate the user to check information.

[0095] Based on the above design idea of arranging the functional device hole 121 on the screen 12 to expand the display area of the screen 12 and realize the large-screen of the screen 12. The present application provides a screen assembly 10, which aims to fix the decorative piece of the camera module 30 on the screen 12. The decorative piece serves as the appearance piece and protective piece of the camera module 30, which can improve the appearance of the camera module 30 and prevent the camera module 30 from being scratched, collided, etc.

[0096] Please refer to FIG. 8, which is a structure schematic diagram of the screen assembly 10 shown in FIG. 7 along the line B-B. The screen assembly 10 includes the screen 12 and the first decorative piece 13. The first back cover 212 is replaced by the screen 12, and the screen 12 includes the cover plate 122, the display panel 123 and the buffer layer 124 which are sequentially stacked.

[0097] The cover plate 122 faces the outside of the first housing 21 and is used to protect the core components in the screen 12, such as the display panel 123 and the touch module. The cover plate 122 is usually made of high-transparency materials, such as glass, plastic or special optical composite materials.

[0098] The display panel 123 is used to display images, and the display surface of the display panel 123 faces the cover plate 122. The user checks the information displayed by the display panel 123 through the cover plate 122.

[0099] The buffer layer 124 is also called super composite film (SCF), and the buffer layer 124 is generally composed of a buffer foam 1241 and an electrostatic discharge layer 1242. The buffer foam 1241 is stacked on the side surface of the display panel 123 away from the cover plate 122, and the buffer foam 1241 is used to play a role of buffering and shock resistance to improve the impact resistance of the screen 12.

[0100] The electrostatic discharge layer 1242 is used to conduct static electricity. The electrostatic discharge layer 1242 is arranged on the side surface of the buffer foam 1241 away from the display panel 123. The electrostatic discharge layer 1242 is adapted to be arranged in grounding. Specifically, a grounding point can be arranged on the screen 12, and the electrostatic discharge layer 1242 is electrically connected to the grounding point. In some embodiments, the grounding point can be arranged on the middle plate or the circuit board of the screen 12. In this way, the electrostatic charge can be discharged through the electrostatic discharge layer 1242, so as to avoid the interference of the electrostatic charge on the electric field of the display panel 123.

[0101] The above only discloses part of the components in the screen 12, and is not a special limitation of the present application. It can be understood that in some other embodiments, the screen 12 can also include other film layers, which will not be described here.

[0102] On the basis of the above, the screen 12 includes a display surface 12a and a non-display surface 12b arranged opposite to each other, wherein the display surface 12a can be understood as the surface of the cover plate 122 away from the display panel 123, and the non-display surface 12b is the surface of the electrostatic discharge layer 1242 away from the buffer foam 1241. The screen 12 further includes a functional device hole 121 penetrating through the display surface 12a and the non-display surface 12b, and at least part of the camera module 30 is located in the functional device hole 121.

[0103] The functional device hole 121 has a first opening 121a located on the display surface 12a, and a second opening 121b located on the non-display surface 12b. The light used for imaging by the camera module 30 enters the camera module 30 through the first opening 121a, and at least part (for example, the lens) of the camera module 30 extends into the functional device hole 121 through the second opening 121b. The shape of the functional device hole 121 includes but is not limited to a circle, a square, a rectangle, an ellipse, an oblong, or a special shape.

[0104] The first decorative piece 13 is used to protect the lens of the camera module 30, so as to avoid scratching or collision of the lens. The first decorative piece 13 is fixed relative to the screen 12 and is arranged at the functional device hole 121. The material of the first decorative piece 13 includes but is not limited to metal, plastic, and a combination of the two. The shape of the outer periphery contour of the first decorative piece 13 can be the same as the shape of the functional device hole 121, and the shape of the outer periphery contour of the first decorative piece 13 includes but is not limited to a circle, a square, a rectangle, an ellipse, an oblong, or a special shape. The embodiments in the present application and the following embodiments are described by taking the shape of the outer periphery contour of the first decorative piece 13 as a circle as an example.

[0105] The first decorative piece 13 has a first through hole 131. The first through hole 131 penetrates the first decorative piece 13 in the thickness direction (i.e., the Z-axis direction) of the first decorative piece 13. The shape of the first through hole 131 includes, but is not limited to, a circle, a square, a rectangle, an ellipse, an oblong, or a special shape. The first through hole 131 is used to accommodate the light entrance end of the lens, so as to allow light to enter the lens.

[0106] The first through hole 131 is opposite to the functional device hole 121, and specifically, the first through hole 131 is coaxially arranged with the functional device hole 121, that is, the central axis of the first through hole 131 coincides with the central axis L1 of the functional device hole 121. Here, the coincidence can include coincidence with a certain error, and the included angle between the central axis of the first through hole 131 and the central axis L1 of the functional device hole 121 is within 5 degrees, which can be understood as "coincidence". The "coincidence" in the following can also be understood in this way, and will not be described hereinafter. It should be noted that the axis of the first through hole 131 and the axis L1 of the functional device hole 121 are coaxially arranged with the optical axis of the camera module 30.

[0107] Please refer to FIG. 9, which is a structural schematic diagram of the screen assembly 10 under stress. However, the first decorative piece 13 is an appearance piece of the camera module 30, and when the electronic device 100 falls or collides, the first decorative piece 13 is easily impacted by stress. Generally, the first decorative piece 13 is easily impacted by stress F1, stress F2, and stress F3. Since the first decorative piece 13 is only fixedly connected with the screen 12, the stress received by the first decorative piece 13 is all transmitted to the screen 12, and in particular, the area Q1 of the screen 12 overlapping with the first decorative piece 13 is under greater stress. When the size of the stress exceeds the maximum stress that the screen 12 can bear, the screen 12 is easily damaged to appear black spots or even be broken, the display function of the screen 12 is damaged, and the user's use is affected.

[0108] To solve the above problems, the present application also provides a screen assembly 10. Please refer to FIG. 10, which is a structural schematic diagram of the screen assembly 10 provided by some embodiments of the present application. The screen assembly 10 includes a screen 12, a first decorative piece 13, and a second decorative piece 14. The specific structure of the screen 12 can refer to the above embodiments, which will not be described here.

[0109] Referring to FIG. 10 and FIG. 11, FIG. 11 is a structural diagram of the first decoration 13 in the screen assembly 10 shown in FIG. 10. The first decoration 13 is located at the side facing the display surface 12a and is fixed to the display surface 12a. In this way, when the space required for installing the camera module 30 is fixed, the first decoration 13 is located outside the first housing 21, the first housing 21 does not need to reserve internal space for the first decoration 13, and the thickness of the first housing 21 can be designed to be thinner, which is conducive to the slimming of the electronic device 100. Moreover, when the installation space reserved by the first housing 21 for the first decoration 13 is fixed, the first decoration 13 is arranged outside the first housing 21, the installation space of the camera module 30 is increased, and the camera module 30 can be provided with a higher-performance lens or a larger-size photosensitive chip, which is conducive to improving the shooting performance of the camera module 30.

[0110] Referring to FIG. 11, the first decoration 13 includes a first part 132, and the first part 132 of the first decoration 13 is located at the first opening 121a, that is, the vertical projection of the first part 132 on the screen 12 is located at the inner circumferential side of the first opening 121a, the first part 132 is annular and surrounds a first through hole 131, and the first through hole 131 is arranged opposite to the functional device hole 121. In some embodiments, the center axis of the first through hole 131 coincides with the center axis of the functional device hole 121.

[0111] Referring to FIG. 10 and FIG. 12, FIG. 12 is a structural diagram of the second decoration 14 provided by some embodiments of the present application. The second decoration 14 can be a metal structure, such as stainless steel or aluminum alloy, to ensure its stability and durability. Moreover, the metal structure can bear a larger stress and has good anti-stress impact performance.

[0112] The second decoration 14 includes a fixed part 141 and a connecting part 142, the fixed part 141 is fixed to the non-display surface 12b, as shown in FIG. 10, the fixed part 141 includes a fixed segment 1411, and the fixed segment 1411 is located at the second opening 121b, that is, the vertical projection of the fixed segment 1411 on the screen 12 is located at the inner circumferential side of the second opening 121b, and the connecting part 142 is located in the functional device hole 121 and is connected between the fixed segment 1411 and the first part 132.

[0113] In this way, the first decorative piece 13 serves as an appearance piece of the screen assembly 10, and when the screen assembly 10 falls or collides, the first decorative piece 13 is easily impacted by stress, compared to the screen assembly 10 including only the first decorative piece 13, that is, the stress borne by the first decorative piece 13 is entirely transmitted to the screen 12. The screen assembly 10 in the embodiment further includes the second decorative piece 14, and the second decorative piece 14 supports the first decorative piece 13 together with the screen 12. When the first decorative piece 13 is impacted by stress, the stress borne by the first decorative piece 13 is first directly transmitted to the screen 12 and the connecting portion 142, and the stress borne by the first decorative piece 13 is transmitted to the fixing portion 141 through the connecting portion 142. Therefore, the stress borne by the first decorative piece 13 can be dispersed to the screen 12 and the second decorative piece 14, effectively dispersing and balancing the stress, avoiding the stress borne by the first decorative piece 13 from being concentrated on the screen 12, and further reducing the risk of the screen 12 being impacted by stress to appear black spots or even being broken, and improving the stability of the overall structure of the screen assembly 10.

[0114] Please continue to refer to FIGS. 10 and 12, in some embodiments, the connecting portion 142 is in a cylindrical shape, and the connecting portion 142 has a second through hole 1421, and the central axis of the second through hole 1421 coincides with the central axis L1 of the functional device hole 121. At least part of the camera module 30 is located in the second through hole 1421, and the inner wall of the second through hole 1421 can be arc-shaped to adapt to the shape of the outer peripheral surface of the lens. The central axis of the second through hole 1421 coincides with the optical axis of the camera module 30, that is, the second through hole 1421 has high concentricity with the camera module 30, thereby reducing refraction and scattering of light during propagation, and further improving the shooting quality of the camera module 30.

[0115] In this way, the second decorative piece 14 is composed of the cylindrical connecting portion 142, and the end of the connecting portion 142 away from the fixing portion 141 surrounds a circumference of the first through hole 131 and is connected with the first portion 132. The cylindrical connecting portion 142 has a more stable structure, has good bearing capacity and stress impact resistance. When the electronic device 100 falls or collides, the stress borne by the first decorative piece 13 is uniformly transmitted to the connecting portion 142 through the first portion 132, and the cylindrical connecting portion 142 can uniformly disperse the stress borne by the first decorative piece 13, reduce stress concentration, and improve the stability of the second decorative piece 14. Moreover, the cylindrical connecting portion 142 can disperse more stress to reduce the stress borne by the screen 12, thereby avoiding the problem of the screen 12 being impacted by stress to appear black spots or even being broken, and improving the stability of the overall structure of the screen assembly 10.

[0116] Please continue to refer to FIG. 12, in some embodiments, the fixing portion 141 is in the shape of a ring sheet, the fixing portion 141 is arranged around the second through hole 1421, and is connected to an end of the connecting portion 142 away from the first portion 132. In this way, the stress borne by the first decorative piece 13 is evenly transmitted to the fixing portion 141 through the connecting portion 142, and part of the stress borne by the first decorative piece 13 is evenly dispersed on the fixing portion 141. The second decorative piece 14 is composed of the connecting portion 142 and the fixing portion 141, which avoids stress concentration of the stress borne by the first decorative piece 13 on the screen 12, avoids stress concentration of the stress borne by the first decorative piece 13 on the connecting portion 142, and avoids stress concentration of the stress borne by the first decorative piece 13 on the fixing portion 141, thereby improving the stability of the overall structure of the screen assembly 10.

[0117] Please refer to FIG. 13, which is a top view of the second decorative piece 14 shown in FIG. 12. In some embodiments, the fixing portion 141 is in the shape of a regular circular ring sheet, which facilitates processing and mass production.

[0118] Please refer to FIG. 14, which is a top view of the second decorative piece 14 provided in some other embodiments of the present application. In some other embodiments, because there are many structural pieces and electronic components arranged in the first accommodating space C1 of the electronic device 100, in order to improve the utilization efficiency of the internal space of the electronic device 100, the outer periphery of the fixing portion 141 can be arranged in an irregular shape. Specifically, the outer periphery of the fixing portion 141 has an avoiding gap 1412, and the number of the avoiding gap 1412 can be one, two, three, etc.

[0119] The fixing portion 141 is located on the non-display surface 12b, that is, the surface of the screen 12 facing the first housing 21, and the fixing portion 141 is located in the first housing 21. The outer periphery of the fixing portion 141 is in an irregular shape. The electronic device 100 further includes other structural pieces arranged on one side of the non-display surface 12b, and the screen 12 has a third region opposite to the other structural pieces, and the fixing portion 141 is provided with the avoiding gap 1412 for accommodating the other structural pieces at the third region. In this way, a larger internal space does not need to be separately avoided in the electronic device 100 for the arrangement of the fixing portion 141, and the fixing portion 141 can be arranged in the gap between adjacent structural pieces in the electronic device 100. That is, the fixing portion 141 can extend to the region in the electronic device 100 having a gap space, so as to expand the supporting area of the fixing portion 141, thereby improving the supporting effect of the second decorative piece 14 on the first decorative piece 13, and avoiding stress concentration of the stress borne by the first decorative piece 13 on the screen 12.

[0120] Please refer to FIG. 15, which is a structural schematic diagram of the second decorative piece 14 according to some embodiments of the present application. The connecting part 142 is in the shape of a strip, a rod or a column. The number of the connecting part 142 can be one, two, three or the like. In the embodiment shown in FIG. 13, the number of the connecting part 142 is two, and the two connecting parts 142 share the support on the first part 132.

[0121] The connecting part 142 is connected between the first part 132 and the fixed segment 1411, and the connecting part 142 can transmit the stress borne by the first decorative piece 13 to the fixed part 141, so that the second decorative piece 14 and the screen 12 jointly bear the stress borne by the first decorative piece 13, avoiding stress concentration of the stress borne by the first decorative piece 13 on the screen 12, and thus improving the stability of the screen assembly 10. Moreover, the connecting part 142 has a simple structure, is easy to process, and is also easy to install the second decorative piece 14, which is conducive to the mass production of the screen assembly 10.

[0122] On the basis of the above-mentioned embodiments, the fixed part 141 can also be in the shape of a strip, a rod or a column, and the number of the fixed part 141 is equal to and corresponds to the number of the connecting part 142. The fixed part 141 is connected to the end of the connecting part 142 away from the first part 132. Similarly, the fixed part 141 of this structure has a simple structure, is easy to process, and is also easy to install the second decorative piece 14, which is conducive to the mass production of the screen 12.

[0123] On the basis of the above-mentioned embodiments, i.e., on the basis of the connecting part 142 being in the shape of a strip, a rod or a column, the fixed part 141 can also be in the shape of a ring sheet. In this way, the stress borne by the first decorative piece 13 is uniformly transmitted to the fixed part 141 through the connecting part 142, and part of the stress borne by the first decorative piece 13 is uniformly dispersed on the fixed part 141.

[0124] Please refer to FIG. 16, which is a structural schematic diagram of the screen assembly 10 and the first structural piece 40 according to some embodiments of the present application. In some embodiments, the electronic device 100 further comprises the first structural piece 40, which is located in the first housing 21 and on the side of the fixed part 141 away from the screen 12. The first structural piece 40 is in contact with the surface of the fixed part 141 facing away from the screen 12. In some embodiments, the first structural piece 40 is a middle plate of the first middle frame 211, and the surface of the fixed part 141 facing away from the screen 12 is in contact with the middle plate. In other embodiments, the first structural piece 40 is a mainboard support, and the surface of the fixed part 141 facing away from the screen 12 is in contact with the mainboard support.

[0125] The first structural member 40 and the fixing portion 141 can be in direct contact, i.e., the surface of the first structural member 40 directly abuts the surface of the fixing portion 141. The first structural member 40 and the fixing portion 141 can also be in indirect contact, i.e., other structural members are further included between the first structural member 40 and the fixing portion 141, and the first structural member 40 and the fixing portion 141 contact each other by means of the other structural members, for example, the other structural members can be a buffer foam 1241, a glue material, a heat-conducting silica gel, etc.

[0126] Here, "contact" includes the following meanings: first, the surface of the first structural member 40 only abuts the surface of the fixing portion 141, and there is no stress of mutual approach or mutual departure between the first structural member 40 and the fixing portion 141; second, the surface of the first structural member 40 abuts the surface of the fixing portion 141, and there is stress of mutual approach between the first structural member 40 and the fixing portion 141, i.e., the first structural member 40 and the fixing portion 141 abut each other.

[0127] In this way, when the electronic device 100 falls or collides, the stress received by the first decorative member 13 is dispersed to the screen 12 and the second decorative member 14, the second decorative member 14 is in contact with the first structural member 40, and the stress received by the first decorative member 13 is transmitted to the first structural member 40 through the second decorative member 14. The first structural member 40 provides a certain supporting effect for the first decorative member 13 through the second decorative member 14, so that the first decorative member 13 remains on the display surface 12a of the screen 12, and the problem that the first decorative member 13 is pressed in the direction close to the screen 12 when it is stressed, and further the problem that the screen 12 is pressed to form a black spot or even broken when the first decorative member 13 is stressed, is avoided.

[0128] The connection mode between the first decorative member 13, the second decorative member 14, and the screen 12 will be described in detail below.

[0129] Please refer to FIG. 17, which is an enlarged view of position C in the screen 12 shown in FIG. 16. In some embodiments, the first decorative member 13 and the second decorative member 14 can be connected by a threaded connecting member 15, for example, a bolt, a screw rod, a screw, etc. However, such a connection mode is more suitable for the application scenario that the first decorative member 13 is installed on the back cover, and when the first decorative member 13 and the second decorative member 14 are installed on the screen 12, such a connection mode will have drawbacks. In detail, when the first decorative member 13 and the second decorative member 14 are connected by the threaded connecting member 15, the locking force between the first decorative member 13 and the second decorative member 14 will be transmitted to the screen 12. Specifically, the locking force provided by the threaded connecting member 15 makes the first decorative member 13 have a force F4 of pressing the screen 12, and the second decorative member 14 have a force F5 of pressing the screen 12.

[0130] Therefore, the screen 12 is located between the first decoration 13 and the second decoration 14, and the screen 12 is deformed or even broken by the extrusion of the first decoration 13 and the second decoration 14, and the display function of the screen 12 is also affected by the extrusion to produce display black spots.

[0131] To solve the above problems, that is, the deformation of the screen 12 and the display function failure caused by the connection of the first decoration 13 and the second decoration 14. Please refer to FIG. 18, which is an enlarged view of the screen assembly 10 provided by some embodiments of the application. In some embodiments, the screen assembly 10 further comprises a first adhesive portion 16 connected between the first part 132 and the connecting portion 142. That is, the first decoration 13 and the second decoration 14 are connected by adhesion. The first adhesive portion 16 can be glue dispensing, back glue, double-sided tape, hot melt adhesive, UV curing adhesive, etc. The first adhesive portion 16 is taken as an example for explanation.

[0132] The first decoration 13 and the second decoration 14 are connected by adhesion instead of threaded connection, which improves the stability of the connection between the structural parts in the screen assembly 10. First, the first adhesive portion 16 can be uniformly arranged between the first part 132 and the connecting portion 142 to tightly bond the first part 132 and the connecting portion 142. Compared with threaded connection, the adhesion method can more evenly distribute the load and reduce the stress concentration problem of the connecting force between the first decoration 13 and the second decoration 14, thereby effectively avoiding damage to the screen 12 due to uneven stress.

[0133] Secondly, the first adhesive portion 16 has good sealing performance, which can seal the gap between the first decoration 13 and the second decoration 14, prevent moisture, dust and other small particles from entering the screen assembly 10 through the gap between the first decoration 13 and the second decoration 14, and protect the internal electronic components of the screen assembly 10 from corrosion and pollution. Further improve the service life of the electronic device 100, and improve the overall performance of the electronic device 100.

[0134] Furthermore, the first decoration 13 and the second decoration 14 are connected by adhesion, which can simplify the assembly process of the first decoration 13 and the second decoration 14 and reduce the production cost. Compared with threaded connection, the first decoration 13 and the second decoration 14 do not need to be provided with threaded holes matched with threaded parts, thereby ensuring the structural strength of the first decoration 13 and the second decoration 14.

[0135] Please continue to refer to FIG. 18, further, in some embodiments, the screen assembly 10 further comprises a second adhesive portion 17 connected between the first decoration 13 and the display surface 12a.

[0136] Referring to FIG. 19, FIG. 19 is a top view of the screen 12 in the screen assembly 10 shown in FIG. 8. The display surface 12a includes a first area 12a1 and a second area 12a2 surrounding the first area 12a1, where the first area 12a1 can be understood as a non-display area of the display surface 12a, and the second area 12a2 can be understood as a display area of the display surface 12a. The first area 12a1 as a non-display area is used to mount the camera module 30, the first opening 121a is formed on the first area 12a1, and the second adhesive portion 17 is also provided on the first area 12a1. The second area 12a2 as a display area is used to present a clear image to the user and to allow the user to touch and interact with the electronic device 100.

[0137] The second adhesive portion 17 has good sealing performance, and can seal the gap between the first decorative piece 13 and the screen 12, so as to prevent moisture, dust and other small particles from entering the screen assembly 10 through the gap between the first decorative piece 13 and the screen 12, and protect the internal electronic components of the screen assembly 10 from corrosion and pollution. Further, the service life of the electronic device 100 is improved, and the overall performance of the electronic device 100 is improved.

[0138] The orthographic projection of the first decorative piece 13 on the screen 12 overlaps the first area 12a1, where "overlaps" includes the following definitions: first, the orthographic projection of the first decorative piece 13 on the screen 12 overlaps the first area 12a1, that is, the periphery of the orthographic projection of the first decorative piece 13 on the screen 12 overlaps the outer periphery of the first area 12a1; second, the orthographic projection of the first decorative piece 13 on the screen 12 is located within the first area 12a1; third, the orthographic projection of the first decorative piece 13 on the screen 12 covers the first area 12a1; and fourth, the orthographic projection of the first decorative piece 13 on the screen 12 partially overlaps the first area 12a1.

[0139] The second adhesive portion 17 can be glue dispensing, back glue, double-sided tape, hot melt glue, UV curing glue, etc. The second adhesive portion 17 in some embodiments of the present application can use double-sided tape, which is convenient to operate, and the substrate of the double-sided tape includes foam, which has good buffering performance and can effectively prevent the screen 12 from being damaged during the pressing process of the first decorative piece 13 and the screen 12, thereby ensuring the stability of the connection between the first decorative piece 13 and the screen 12.

[0140] In summary, the first adhesive portion 16 can be glue dispensing, and the second adhesive portion 17 can be double-sided tape. The first decorative piece 13 is connected to the screen 12 by the double-sided tape. The process of connecting the first decorative piece 13 to the screen 12 by the double-sided tape generally includes the following steps. Please refer to FIG. 20, which is a process diagram of the screen assembly 10 in the glue dispensing process according to some embodiments of the present application. First, clean the adhesive area, i.e., clean the first area 12a1 and the surface of the first decorative piece 13 facing the screen 12. Second, attach the double-sided tape to the surface of the first area 12a1 or the first decorative piece 13 facing the screen 12. After the double-sided tape is attached, the first decorative piece 13 is attached to the screen 12. Third, perform a pressure holding process on the first decorative piece 13 and the screen 12 by using a pressure holding jig 50. Finally, the glue is cured, and the first decorative piece 13 is attached to the screen 12.

[0141] Please refer to FIG. 21, which is a structural diagram of the pressure holding process in the glue dispensing process of the screen assembly 10 shown in FIG. 20. However, during the pressure holding process of the first decorative piece 13 and the screen 12, the first decorative piece 13 is prone to slipping relative to the surface of the screen 12. The embodiment shown in FIG. 21 is described by taking the first decorative piece 13 slipping in the negative direction of the Y-axis relative to the screen 12 as an example. This is only an exemplary description of the present application and is not a special limitation of the present application. In some other embodiments, the first decorative piece 13 slips in any direction in the XY plane relative to the screen 12.

[0142] Please refer to FIG. 22, which is a comparison diagram of the change of the field of view range of the lens after the first decorative piece 13 slips during the pressure holding process of the screen assembly 10 shown in FIG. 21. During the pressure holding process, the first decorative piece 13 slips relative to the screen 12, and the concentricity of the first through hole 131 of the first decorative piece 13 and the functional device hole 121 is low. Here, the “concentricity” refers to the degree of coincidence of the center axis of the first through hole 131 and the center axis of the functional device hole 121. The low concentricity of the first through hole 131 and the functional device hole 121 means that the center axis of the first through hole 131 is greatly offset relative to the center axis of the functional device hole 121.

[0143] When the concentricity of the first through hole 131 and the functional device hole 121 is low, the first decorative piece 13 will affect the field of view range of the camera module 30. The field of view range is usually represented by the field of view (FOV), which is the angle range of the width and height of the picture that can be captured by the camera.

[0144] When the concentricity of the first through hole 131 and the functional device hole 121 is in the ideal range, the field of view range of the camera module 30 is as shown in the first angle a1 in FIG. 22. In general, the field of view range of the camera module 30 is 60-120 degrees. When the concentricity of the first through hole 131 and the functional device hole 121 is low due to the offset of the first decorative piece 13 relative to the screen 12, the first decorative piece 13 will cover part of the original field of view range of the camera module 30. In this way, the field of view range a2 of the camera module 30 is reduced, and the range of the camera module 30 is reduced, which reduces the shooting quality of the camera module 30.

[0145] Referring to FIG. 23, FIG. 23 is a structural schematic diagram of a screen assembly provided by some embodiments of the present application. In order to avoid the sliding of the first decorative piece 13 relative to the surface of the screen 12 in the pressure maintaining process, in some embodiments, the first decorative piece 13 further comprises a limiting portion 133, which is located in the functional device hole 121, and the limiting portion 133 is in contact with the inner wall of the functional device hole 121, that is, the limiting portion 133 is in contact with the cover plate 122. When the first decorative piece 13 is installed in the functional device hole 121, the limiting portion 133 of the first decorative piece 13 extends into the functional device hole 121. When the first decorative piece 13 has a tendency to slide relative to the screen 12 in the pressure maintaining process of the first decorative piece 13 and the screen 12, the limiting portion 133 abuts against the inner wall of the functional device hole 121, thereby avoiding the sliding of the first decorative piece 13 relative to the screen 12.

[0146] In this way, the first decorative piece 13 is provided with the limiting portion 133 to avoid the problem of the sliding of the first decorative piece 13 relative to the screen 12 in the pressure maintaining process, thereby ensuring the concentricity of the first through hole 131 and the functional device hole 121 after the first decorative piece 13 is fixed to the screen 12, and further ensuring the shooting quality of the camera module 30.

[0147] In the above embodiments, although the problem of the sliding of the first decorative piece 13 relative to the screen 12 can be avoided by providing the limiting portion 133, in the pressure maintaining process of the bonding of the first decorative piece 13 and the second decorative piece 14, the second decorative piece 14 has a tendency to slide relative to the first decorative piece 13. In this way, the concentricity of the second through hole 1421 on the second decorative piece 14 and the functional device hole 121 cannot be ensured, thereby causing the problem of the reduction of the shooting quality of the camera module 30. In addition, the connecting surface of the first decorative piece 13 and the second decorative piece 14 is located in the screen 12. When the second decorative piece 14 slides relative to the first decorative piece 13, the second decorative piece 14 is prone to collide with the display panel 123, thereby causing the damage of the display panel 123 and affecting the display function of the screen assembly 10.

[0148] In addition to the above problems that the screen assembly 10 faces during installation, when the screen assembly 10 is installed and in use, if the first adhesive portion 16 between the first decorative piece 13 and the second decorative piece 14 fails when the screen assembly 10 falls or collides, the second decorative piece 14 will also slip relative to the first decorative piece 13, and the second decorative piece 14 is also prone to colliding with the display panel 123, thereby causing damage to the display panel 123 and affecting the display function of the screen assembly 10.

[0149] To avoid the problem of the first decorative piece 13 slipping relative to the surface of the screen 12 during the pressure maintaining process, and to avoid the problem of the first decorative piece 13 and the second decorative piece 14 colliding with the display panel 123, the present application also provides a screen assembly 10, wherein the dynamic friction coefficient of the first region 12a1 is greater than the dynamic friction coefficient of the second region 12a2.

[0150] The dynamic friction coefficient (also known as the dynamic friction factor or sliding friction coefficient) is a physical quantity that describes the relationship between the friction force and the normal pressure between two objects when they are sliding relative to each other. The dynamic friction coefficient refers to the ratio of the sliding friction force to the normal pressure between the two objects when they are sliding relative to each other on the contact surface. The greater the dynamic friction coefficient, the more difficult it is for the two objects to slide relative to each other on the contact surface, and a greater external force is required to make the objects start to slide due to the greater friction force.

[0151] The dynamic friction coefficient of the first region 12a1 is greater than the dynamic friction coefficient of the second region 12a2, so that the friction between the first decorative piece 13 and the screen 12 is increased during the pressure maintaining process, avoiding the first decorative piece 13 from slipping relative to the screen 12, thereby ensuring the concentricity of the functional device and the first through-hole 131, and also ensuring the shooting quality of the camera module 30.

[0152] In some embodiments, the dynamic friction coefficient of the first region 12a1 is greater than or equal to 0.1, for example, the dynamic friction coefficient of the first region 12a1 can be 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, etc. In this way, the first region 12a1 has a larger roughness, which can more effectively prevent the first decorative piece 13 from slipping relative to the screen 12, thereby ensuring the concentricity of the functional device and the first through-hole 131, and also ensuring the shooting quality of the camera module 30.

[0153] To improve the waterproof, oil-proof and anti-fingerprint performance of the screen 12, the surface of the screen 12 is usually provided with an anti-fingerprint coating (Anti-Fingerprint, AF layer). The AF layer is usually a fluorine-containing coating. The anti-fingerprint coating has extremely low surface tension, and the roughness of the AF layer is extremely low, thereby achieving the effects of hydrophobicity, oil resistance and anti-fingerprint.

[0154] Referring to FIG. 24, FIG. 24 is a structural schematic diagram of the screen assembly 10 according to some embodiments of the present application. In order to improve the roughness of the first area 12a1, the screen 12 further comprises a friction-increasing layer, which covers the AF layer to improve the roughness of the first area 12a1. The cover plate 122 has a first surface 122a, and the friction-increasing layer is arranged on the first surface 122a. The side surface of the friction-increasing layer opposite to the first surface 122a defines the first area 12a1, and the area on the first surface 122a outside the periphery of the friction-increasing layer is the second area 12a2. The friction-increasing layer can be printed on the first area 12a1 by a printing template.

[0155] In this way, the first area 12a1 improves the roughness by arranging the friction-increasing layer, and the friction-increasing layer is simple to arrange and easy to operate. Moreover, the friction-increasing layer can prevent the first decorative piece 13 from slipping relative to the screen 12, thereby ensuring the concentricity of the functional device and the first through hole 131, and ensuring the shooting quality of the camera module 30.

[0156] In some embodiments, the friction-increasing layer is an ink layer, and the ink layer arranged between the first decorative piece 13 and the screen 12 is defined as a first ink layer 125. First, the first ink layer 125 can improve the roughness of the first area 12a1, thereby preventing the first decorative piece 13 from slipping relative to the screen 12 during the pressure maintaining process. Second, the first ink layer 125 can improve the adhesion between the second adhesive part 17 and the first area 12a1, thereby improving the adhesion between the first decorative piece 13 and the screen 12. Finally, the first ink layer 125 can shield the inside of the screen assembly 10, preventing the user from observing the structure inside the screen assembly 10 from the outside, thereby playing a role of hiding the ugliness and improving the aesthetics of the screen assembly 10 and the electronic device 100.

[0157] Generally, the ink layer used to shield the inside of the screen assembly 10 is usually arranged between the cover plate 122 and the display panel 123, and the first ink layer 125 of the present embodiment can improve the dynamic friction coefficient of the first area 12a1 while playing a role of hiding the ugliness. Therefore, the screen assembly 10 can omit the ink layer arranged between the cover plate 122 and the display panel 123, and in this way, the first ink layer 125 does not occupy the space inside the electronic device 100, thereby improving the utilization rate of the space inside the electronic device 100.

[0158] Please continue to refer to FIG. 24, in some embodiments, the first decorative piece 13 includes a second surface 13a facing the display surface 12a, the dynamic friction coefficient of the second surface 13a is greater than or equal to the dynamic friction coefficient of the first area 12a1. In some embodiments, the first decorative piece 13 can be directly selected from a material with a larger roughness to be processed and manufactured, so that a second surface 13a with a larger dynamic friction coefficient can be directly obtained. In other embodiments, the dynamic friction coefficient of the second surface 13a can be increased by referring to the method of increasing the dynamic friction coefficient of the first area 12a1, that is, by setting an ink layer.

[0159] In this way, the adhesion of the second adhesive portion 17 to the first decorative piece 13 is increased, which can prevent the first decorative piece 13 from slipping relative to the screen 12, thereby ensuring the concentricity of the functional device and the first through-hole 131, and also ensuring the shooting quality of the camera module 30.

[0160] Please continue to refer to FIG. 24, in some embodiments, the connecting portion 142 includes a third surface 142a facing the first decorative piece 13, the dynamic friction coefficient of the third surface 142a is greater than or equal to the dynamic friction coefficient of the first area 12a1. Similarly, the dynamic friction coefficient of the third surface 142a can also be increased by referring to the method of increasing the dynamic friction coefficient of the first area 12a1, that is, by setting an ink layer. In this way, the third surface 142a has a larger roughness, which can increase the friction between the first decorative piece 13 and the second decorative piece 14, further preventing the first decorative piece 13 from slipping relative to the screen 12, thereby ensuring the concentricity of the functional device and the first through-hole 131, and also ensuring the shooting quality of the camera module 30.

[0161] In some embodiments, the third surface 142a can increase the dynamic friction coefficient by setting an ink layer, which is defined as a second ink layer 134 in the present embodiment. In this way, first, the second ink layer 134 can increase the roughness of the third surface 142a, increase the friction between the first decorative piece 13 and the second decorative piece 14, and thereby prevent the first decorative piece 13 from slipping relative to the screen 12 during the pressure maintaining process. Second, the second ink layer 134 can increase the adhesion between the first decorative piece 13 and the second decorative piece 14 to increase the adhesion between the first decorative piece 13 and the second decorative piece 14. Finally, the second ink layer 134 can shield the inside of the screen assembly 10, preventing the user from observing the structure inside the screen assembly 10 from the outside, playing a role in hiding ugliness, and improving the aesthetics of the screen assembly 10 and the electronic device 100.

[0162] In some other embodiments, the first area 12a1 can also increase the dynamic friction coefficient in other ways. For example, the first area 12a1 has a concave-convex structure, and the concave-convex area increases the roughness of the first area 12a1, which can avoid the first decorative part 13 from slipping relative to the screen 12, thereby ensuring the concentricity of the functional device and the first through hole 131, and also ensuring the shooting quality of the camera module 30. In addition, the concave-convex structure can increase the bonding area of the second bonding part 17 and the first area 12a1, thereby increasing the bonding force between the first decorative part 13 and the screen 12, and improving the stability of the screen assembly 10.

[0163] Please refer to FIG. 25 and FIG. 26, FIG. 25 is a structural schematic diagram of the screen 12 provided by some embodiments of the present application; and FIG. 26 is a structural schematic diagram of the screen 12 provided by some other embodiments of the present application. The concave-convex structure 126 is arranged on the first area 12a1. The concave-convex structure 126 can be a groove recessed relative to the display surface 12a, or a convex part protruding relative to the display surface 12a, or both a groove recessed relative to the display surface 12a and a convex part protruding relative to the display surface 12a. The first area 12a1 increases the roughness by arranging the groove and the convex part.

[0164] The concave-convex structure of the first area 12a1 can be arranged by the following process.

[0165] The concave-convex structure 126 can be obtained by laser engraving the first area 12a1. Specifically, the first area 12a1 is locally irradiated by a high-energy-density laser beam, so that the surface of the first area 12a1 changes physically or chemically, thereby obtaining the concave-convex structure 126.

[0166] The concave-convex structure 126 can be obtained by surface etching and frosting the first area 12a1. Specifically, a chemical etching or physical frosting process can be used to form a micro concave-convex structure 126 on the surface of the first area 12a1 to increase the roughness of the first area 12a1.

[0167] The concave-convex structure 126 can also be obtained by nano-particle coating. Specifically, a coating layer containing nano-particles, such as silicon dioxide, aluminum oxide or other low-refractive-index materials, is coated on the surface of the first area 12a1. The nano-particles can form a rough surface of the first area 12a1.

[0168] The concave-convex structure 126 can also be obtained by surface microstructure manufacturing. Specifically, techniques such as photolithography, ion beam etching, and laser processing are used to manufacture micron or nanometer-level surface structures, such as moth-eye structures, moth-eye arrays, photonic crystals, etc.

[0169] The concave-convex structure 126 can also be obtained by surface texturing, specifically, by forming a specific texture, such as frosted texture, texture array, etc. on the surface of the first area 12a1 through mold design or molding process. These textures form the concave-convex structure 126 to increase the surface roughness of the first area 12a1.

[0170] The concave-convex structure 126 can also be obtained by plasma treatment, specifically, by using plasma technology to change the chemical and physical properties of the surface of the first area 12a1, forming a rough microstructure to obtain the concave-convex structure 126.

[0171] Similarly, the dynamic friction coefficient of the second surface 13a can also be increased by setting the concave-convex structure 126 to increase the roughness. The third surface 142a can also be increased by setting the concave-convex structure 126 to increase the roughness. Please refer to FIG. 27, which is a structural schematic diagram of the screen assembly 10 provided by some embodiments of the present application. The first area 12a1 uses the first ink layer 125 to increase the roughness, and the second surface 13a and the third surface 142a use the concave-convex structure 126 to increase the roughness.

[0172] In this way, the first ink layer 125 can not only increase the roughness of the first area 12a1, but also play a role in hiding defects. The first decorative part 13 and the second decorative part 14 use the concave-convex structure 126 to increase the roughness. Since the structural strength of the first decorative part 13 and the second decorative part 14 is greater than that of the screen 12, the process of the concave-convex structure 126 will not cause damage to the first decorative part 13 and the second decorative part 14. Moreover, the second surface 13a and the third surface 142a can use the concave-convex structure 126 to increase the roughness, which can further effectively avoid the problem of the first decorative part 13 slipping relative to the screen 12.

[0173] Please continue to refer to FIG. 27. In some embodiments, the screen assembly 10 further comprises a third adhesive part 18 connected between the buffer layer 124 and the fixing part 141. In some embodiments, the assembly process of the screen assembly 10 can be: first, the first decorative part 13 is adhered to the screen 12; second, the second decorative part 14 is adhered to the buffer layer 124, and the second decorative part 14 is adhered to the first decorative part 13. In other embodiments, the assembly process of the screen assembly 10 can also be: first, the second decorative part 14 is adhered to the buffer layer 124; second, the first decorative part 13 is adhered to the screen 12, and the second decorative part 14 is adhered to the first decorative part 13.

[0174] In this way, the first decorative piece 13, the second decorative piece 14 and the screen 12 form a sandwich structure, improving the stability of the screen assembly 10. After the bonding of the components in the screen assembly 10 is completed, the screen assembly 10 is assembled together to the first housing 21, improving the assembly efficiency of the electronic device 100. When the assembly of the screen assembly 10 and the assembly of the screen assembly 10 and the electronic device 100 are not in the same production line, the components in the screen assembly 10 are connected to each other, facilitating the transfer of the screen assembly 10. Moreover, the screen assembly 10 can be sold as a separate product, and the first decorative piece 13, the second decorative piece 14 and the screen 12 are connected to each other, facilitating the transportation and sale of the screen assembly 10.

[0175] In some embodiments, the fixing portion 141 and the connecting portion 142 are an integral structure. In this way, the bonding of the second decorative piece 14 and the screen 12 and the bonding of the second decorative piece 14 and the first decorative piece 13 can be completed in the same process, improving the assembly efficiency of the screen assembly 10. Moreover, the fixing portion 141 and the connecting portion 142 are an integral structure, also improving the stability of the second decorative piece 14 in dispersing the stress received by the first decorative piece 13, and further improving the stability of the screen assembly 10.

[0176] Please refer to FIG. 28, which is an enlarged view of D in the screen assembly 10 shown in FIG. 24. In some embodiments, the first portion 132 has a first groove 132a opening towards the connecting portion 142, and at least part of the first bonding portion 16 is accommodated in the first groove 132a. In this way, the area of the bonding of the first bonding portion 16 and the first portion 132 is improved, and further the connection strength between the first decorative piece 13 and the second decorative piece 14 is improved, further improving the stability of the screen assembly 10.

[0177] Please continue to refer to FIG. 28. In some embodiments, the first decorative piece further includes a second groove 132b opening towards the first area 12a1, and at least part of the second bonding portion 17 is accommodated in the second groove 132b. In this way, in the thickness direction of the electronic device 100, the first bonding portion 16 and the second bonding portion 17 do not occupy too high a thickness, and further the height of the first decorative piece 13 protruding from the screen 12 is reduced, which is beneficial to the aesthetics of the electronic device 100.

[0178] In other embodiments, the connecting portion 142 also has a groove opening towards the first portion 132, and at least part of the first bonding portion 16 is accommodated in the groove. In this way, the area of the bonding of the first bonding portion 16 and the connecting portion 142 is improved, and further the connection strength between the first decorative piece 13 and the second decorative piece 14 is improved, further improving the stability of the screen assembly 10.

[0179] Referring to FIG. 29, FIG. 29 is a structural schematic diagram of the screen assembly 10 provided by some embodiments of the present application. The cover plate 122 has a first surface 122a and a fourth surface 122b opposite to each other, and the fourth surface 122b faces the display panel 123. At least part of the first adhesive portion 16 is located in the functional device hole 121, and the first adhesive portion 16 is located on the side of the fourth surface 122b facing the first surface 122a.

[0180] In this way, the volume of the first adhesive portion 16 is enlarged, and the bonding strength of the first decorative piece 13 and the second decorative piece 14 is improved. When the screen assembly 10 falls or collides, even if the second decorative piece 14 slips a small distance relative to the first decorative piece 13 due to loosening, the second decorative piece 14 will only be extruded against the cover plate 122, and the second decorative piece 14 will not be extruded against the display panel 123, thereby protecting the display function of the screen assembly 10 in the collision scenario and avoiding the display function of the screen assembly 10 from being invalid.

[0181] Please continue to refer to FIG. 29. In some embodiments, the side surface of the first decorative piece 13 opposite to the screen 12 has a receiving groove 135, and the first through-hole 131 is located at the groove bottom wall of the receiving groove 135. The screen assembly 10 further includes a light-transmitting plate 136 fixed in the receiving groove 135 and covering the first through-hole 131. In this way, the light-transmitting plate 136 can prevent moisture and dust from entering the inside of the camera module 30, avoid damaging the camera module 30, and ensure the performance of the camera module 30.

[0182] In some embodiments, the connecting portion 142 has a protruding portion protruding towards the first groove 132a and in contact with the inner wall of the first groove 132a. In this way, when the first decorative piece 13 is bonded to the screen 12, the protruding portion is in contact with the inner wall of the first groove 132a, which can avoid the first decorative piece 13 from slipping relative to the screen 12, thereby ensuring a high concentricity between the first through-hole 131 and the functional device hole 121, and further ensuring the shooting quality of the camera module 30.

[0183] The above embodiments are described by taking the electronic device 100 as a foldable mobile phone as an example. In some other embodiments, the electronic device 100 can also be a straight mobile phone.

[0184] In the description of the present specification, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0185] Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present application, and are not intended to limit the same; although the present application has been described in detail with reference to the foregoing examples, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
