Description

Technical Field

[0001] This application relates to the field of display technologies, and in particular, to a screen assembly and a display device. Background Art

[0002] Display devices such as mobile phones and tablet computers usually implement the display function by means of a screen, and a camera may be provided on the screen side to capture an image in front of the screen by means of the camera on the screen side.

[0003] On the screens of some display devices, a camera decoration is required to protect and decorate the camera on the screen side. Moreover, as the functions of the camera on the screen side gradually increase and the height gradually increases, the camera decoration often protrudes outwardly on the screen. In this way, when impacted by an external force, the camera decoration is likely to transmit the external force to the screen, thereby causing problems such as black spots or imprints on the screen. Summary of the Invention

[0004] This application provides a screen assembly and a display device, which can reduce the possibility of black spots or imprints on the screen.

[0005] To achieve the above object, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, a screen assembly is provided. The screen assembly includes a screen and a camera decoration.

[0007] The screen has a display side and a back side. The display side is the side where the screen displays videos or images, and the back side is opposite to the display side. The screen is provided with at least one through hole communicating the display side and the back side. Herein, "at least one" means a quantity of one or more.

[0008] The camera decoration includes an outer decoration, an inner decoration, and at least one force-relieving boss. At least a part of the outer decoration is located on the display side of the screen. The part of the outer decoration located on the display side is the outer decoration body, and the distance between the outer decoration body and the screen is a first distance.

[0009] At least a part of the inner decoration is located on the back side of the screen. The part of the inner decoration located on the back side is the inner decoration body. The above at least one boss is located between the outer decoration body and the inner decoration body, and at least one force-relieving boss is received in at least one through hole.

[0010] At least one force-relieving boss is provided on the inner decoration body, and the distance between at least one force-relieving boss and the outer decoration body is a second distance. Alternatively, at least one force-relieving boss is provided on the outer decoration body, and the distance between at least one force-relieving boss and the inner decoration body is a second distance. The second distance is less than the first distance.

[0011] In this way, when an external force acts on the camera decorative part, the outer decorative part moves towards the screen, and before contacting the screen, it contacts at least one force-relieving boss of the inner decorative part, or contacts the main body of the inner decorative part by means of at least one force-relieving boss, so as to release at least a part of the external force from at least one force-relieving boss to the inner decorative part, and further release it through the inner decorative part. Thus, the inner decorative part and the screen share the impact force from the outer decorative part together, which can reduce the impact force of the outer decorative part on the screen and reduce the possibility of black spots or imprinting on the screen. The position where the force-relieving boss is located is the first force-relieving part.

[0012] Optionally, the difference between the first distance and the second distance is greater than or equal to 0.05 mm. Optionally, the difference between the first distance and the second distance can be 0.05 mm, 0.08 mm, 0.1 mm, 0.15 mm, 0.18 mm or 0.2 mm. When the difference is within this range, the height of the force-relieving boss protruding from the display surface is relatively large, which can effectively prevent the outer decorative part from impacting the screen under the action of an external force. Herein, the display surface refers to the surface of the screen facing the display side, and this display surface includes a display area opposite to the internal pixel points of the screen and a non-display area opposite to the internal lead area.

[0013] Optionally, the screen is further provided with a first mounting hole communicating the display side and the back side. The outer decorative part and the inner decorative part are connected via the first mounting hole. That is to say, the outer decorative part and the inner decorative part are connected, and the part of the outer decorative part for connecting with the inner decorative part and / or the part of the inner decorative part for connecting with the outer decorative part are accommodated in the first mounting hole. Moreover, the outer decorative part and the inner decorative part limit the screen from the display side and the back side respectively, whereby the camera decorative part can be connected to the screen. This structure is simple and easy to implement.

[0014] Moreover, a second force-relieving part is formed at the connecting part of the outer decorative part and the inner decorative part in the first mounting hole. When an external force acts on the camera decorative part, in addition to transferring a part of the component force of the external force from the aforementioned first force-relieving part to the inner decorative part, the outer decorative part can also transfer another part of the component force of the external force from this second force-relieving part to the inner decorative part. Thus, the external force released to the inner decorative part can be increased, and the impact force of the outer decorative part on the screen can be reduced, thereby further reducing the possibility of black spots or imprinting on the screen.

[0015] On the above basis, optionally, at least one through hole is located on the outer peripheral side of the first mounting hole. The outer peripheral side of the first mounting hole refers to the side of the inner wall surface of the first mounting hole facing away from the central axis of the first mounting hole. In this way, the first through hole does not overlap with the first mounting hole, and the first force-relieving part does not overlap with the second force-relieving part. Part of the impact force received by the outer decorative part can be released to the inner decorative part from two different positions, namely the first force-relieving part and the second force-relieving part, which can improve the force-relieving efficiency.

[0016] Optionally, the interior decoration component includes a first connecting boss. The first connecting boss is accommodated in the first mounting hole, and at least a portion of the exterior decoration component is connected to the first connecting boss. In this way, the first connecting boss forms a portion of the interior decoration component for connecting to the exterior decoration component. The exterior decoration component does not need to be provided with a boss, so the profile is simple, which can reduce the difficulty of processing the exterior decoration component.

[0017] Optionally, the outer decorative part includes a second connecting boss, the second connecting boss is accommodated in the first mounting hole, and the second connecting boss is connected to the inner decorative part body. In this way, the second connecting boss forms a part of the outer decorative part for connecting with the inner decorative part. The inner decorative part does not need to be provided with a boss, so the profile is simple, which can reduce the difficulty of processing the inner decorative part.

[0018] Optionally, the interior decoration includes a first connecting boss, and the exterior decoration includes a second connecting boss. The first connecting boss and the second connecting boss are both accommodated in the first mounting hole, and the first connecting boss is connected to the second connecting boss. In this way, the first connecting boss forms a portion on the interior decoration for connecting to the exterior decoration, and the second connecting boss forms a portion on the exterior decoration for connecting to the interior decoration. The first connecting boss and the second connecting boss are arranged at a relatively small height. During the assembly process, the first connecting boss and the second connecting boss can both cooperate with the first mounting hole to limit the exterior decoration and the interior decoration, thereby ensuring assembly accuracy.

[0019] Optionally, the number of through holes in at least one through hole is two, and the two through holes are symmetrically distributed relative to the central axis of the first mounting hole. The number of force relief bosses in at least one force relief boss is also two, and the two force relief bosses are respectively accommodated in the two through holes. In this way, the number of through holes is small, which can reduce the opening area on the screen and ensure the structural strength of the screen. Moreover, the number of first force relief parts is two, and the two first force relief parts are respectively located on opposite sides of the second force relief part, which can ensure the stability of the force relief.

[0020] Optionally, the number of through holes in at least one through hole is three, and the three through holes are evenly distributed along the circumference of the first mounting hole. The circumference of the first mounting hole refers to the direction around the central axis of the first mounting hole. The three through holes are evenly distributed along the circumference of the first mounting hole means that along the circumference of the first mounting hole, the central angles of any two adjacent through holes relative to the central axis of the first mounting hole are approximately equal, and the distances from the three through holes to the central axis of the first mounting hole are also approximately equal. The number of force relief bosses in at least one force relief boss is also three, and the three force relief bosses are respectively accommodated in three through holes. In this way, when external force acts on the camera decorative part, the three force relief bosses can be used to stably support the external decorative part, thereby preventing the external decorative part from tilting when the external force is eccentric, thereby avoiding the external decorative part from impacting the screen as much as possible.

[0021] Optionally, at least one through hole is arranged at intervals with the first mounting hole. In this way, the first force-relieving part and the second force-relieving part are arranged at intervals, which can avoid the concentration of the force-relieving parts, prevent the outer decorative member from tilting under the action of an external force, and thus avoid the outer decorative member impacting the screen.

[0022] Optionally, at least one through hole communicates with the first mounting hole. In this way, the distance between at least one through hole and the first mounting hole can be designed to be shorter, which can reduce the area of the occupied region of the through hole and the first mounting hole on the screen, is beneficial to reducing the size of the camera decorative member, and increasing the screen-to-body ratio of the screen assembly.

[0023] Optionally, the screen is further provided with a second mounting hole communicating the display side and the back side, the second mounting hole is arranged at intervals with the first mounting hole, and the outer decorative member and the inner decorative member are further connected via the second mounting hole. In this way, the connecting part of the outer decorative member and the inner decorative member in the second mounting hole is the third force-relieving part. When an external force acts on the camera decorative member, the outer decorative member can also transfer a part of the component force of the external force to the inner decorative member through the third force-relieving part. The third force-relieving part cooperates with the aforementioned first force-relieving part and the second force-relieving part, and can discharge more external force to the inner decorative member, which can further reduce the impact force of the outer decorative member on the screen, and thus further reduce the possibility of the screen generating black spots or imprints.

[0024] On the basis of the above, optionally, at least one through hole is located between the first mounting hole and the second mounting hole. With the cooperation of the first force-relieving part, the second force-relieving part and the third force-relieving part in the at least one through hole, the impact force discharged from the outer decorative member to the screen can be effectively reduced, and there is no need to additionally provide through holes at other positions, which is beneficial to reducing the area of the opening region on the screen and reducing the size of the camera decorative member.

[0025] Optionally, the plane passing through the central axis of the first mounting hole and the central axis of the second mounting hole is the reference plane. Based on this, the number of through holes in at least one through hole is one, and this one through hole is an elongated hole, and the length direction of the elongated hole is perpendicular to the reference plane. The cross-sectional shape of the force-relieving boss is strip-shaped, the force-relieving boss is accommodated in the elongated hole, and the length direction of the cross-section of the force-relieving boss is consistent with the length direction of the elongated hole. In this way, when an external force acts on the camera decorative member, the supporting range of the force-relieving boss for the outer decorative member is large, which can improve the force-relieving efficiency.

[0026] Optionally, the screen includes a light-transmitting cover plate and a display module arranged in a stacked manner. At least one through hole is arranged on the light-transmitting cover plate. The display module is provided with a first avoidance hole, and the first avoidance hole is at least opposite to and communicates with at least one through hole, and the main body of the inner decorative member is accommodated in the first avoidance hole. In this way, the main body of the inner decorative member is sunk in the first avoidance hole, which can avoid the height of the main body of the inner decorative member protruding from the back side being too high and affecting the structural compactness of the whole machine.

[0027] Optionally, the camera decorative member further includes a first adhesive layer, which includes but is not limited to a back adhesive or a dot adhesive, and the first adhesive layer is bonded between the outer decorative member body and the screen. The first adhesive layer bonds the outer decorative member to the screen, which can improve the connection stability of the camera decorative member on the screen.

[0028] Optionally, the camera decorative member further includes a second adhesive layer, which is bonded between the outer decorative member body and the first connecting boss. In this way, there is no need to drill holes in the outer decorative member and the inner decorative member, which can ensure the structural strength and integrity.

[0029] Furthermore, the first adhesive layer can be annular, and the first mounting hole and at least one of the above through holes are located within the area surrounded by the first adhesive layer. In this way, the first adhesive layer plays a waterproof and sealing role, and can prevent moisture outside the display device from entering the through hole or the first mounting hole through the gap between the outer decorative member body and the screen.

[0030] Optionally, the outer decorative member is a metal member. The material of the outer decorative member can be stainless steel, aluminum alloy, copper alloy, magnesium alloy or titanium alloy. The texture of the metal is good, which can improve the appearance performance of the display device, and the hardness of the metal is large, which can improve the anti-deformation ability of the outer decorative member.

[0031] Optionally, the inner decorative member is a plastic member. The material of the inner decorative member can be PC, PC + glass fiber and ABS plastic. The plastic can be formed into a complex surface by an integral injection molding process, and the molding difficulty is low, and the cost and density of the plastic material are small, which can reduce the cost and weight of the inner decorative member.

[0032] In a second aspect, a screen assembly is further provided, and the screen assembly includes a screen and a camera decorative member.

[0033] The screen has a display side and a back side, the display side is the side where the screen displays videos or images, and the back side is opposite to the display side. The screen is provided with a first mounting hole communicating the display side and the back side.

[0034] The camera decorative member includes an outer decorative member and an inner decorative member, and the outer decorative member is connected to the inner decorative member via the first mounting hole.

[0035] At least a part of the outer decorative member is located on the display side of the screen, and the part of the outer decorative member located on the display side is the outer decorative member body, and the outer decorative member body is connected to the display surface of the screen. At least a part of the inner decorative member is located on the back side of the screen, and the part of the inner decorative member located on the back side is the inner decorative member body, and the inner decorative member body is connected to the back of the screen.

[0036] In this way, when an external force acts on the camera decorative part, the outer decorative part moves towards the screen, discharging a part of the external force from the display surface to the screen and another part from the back surface to the screen. Thus, the display surface and the back surface of the screen can share the external force, avoiding stress concentration and reducing the possibility of black spots or imprints on the screen.

[0037] Optionally, a first adhesive layer can be provided between the main body of the outer decorative part and the display surface of the screen, and the main body of the outer decorative part is adhered to the display surface of the screen by means of the first adhesive layer. In this way, neither the main body of the outer decorative part nor the screen needs to be additionally perforated, ensuring the structural strength.

[0038] Optionally, a fourth adhesive layer can be provided between the main body of the inner decorative part and the back surface of the screen, and the fourth adhesive layer includes but is not limited to back glue or dot glue. The main body of the inner decorative part is adhered to the back surface of the screen by means of the fourth adhesive layer. In this way, neither the screen nor the inner decorative part needs to be additionally perforated, ensuring the structural strength.

[0039] Optionally, the screen includes a light-transmitting cover plate and a display module arranged in a stacked manner. The first mounting hole is provided on the light-transmitting cover plate; the display module is provided with a second avoidance hole, the second avoidance hole is opposite to and communicated with the first mounting hole, the area of the second avoidance hole is larger than the area of the first mounting hole, and the surface area of the light-transmitting cover plate facing the second avoidance hole forms a partial area of the back surface of the screen. The main body of the inner decorative part is accommodated in the second avoidance hole and connected to the surface area of the light-transmitting cover plate facing the second avoidance hole.

[0040] In this way, by sharing the external force through the display surface and the back surface of the light-transmitting cover plate, stress concentration can be avoided and damage to the display module can be prevented. Moreover, since the main body of the inner decorative part is sunk in the second avoidance hole, the height of the main body of the inner decorative part protruding from the back surface side can be avoided from being too high, which affects the structural compactness of the whole machine.

[0041] Optionally, the screen includes a light-transmitting cover plate and a display module arranged in a stacked manner; at least a part of the surface of the display module facing away from the light-transmitting cover plate forms at least a partial area of the back surface of the screen; at least a part of the inner decorative part is located on the side of the display module facing away from the light-transmitting cover plate and is connected to the surface of the display module facing away from the light-transmitting cover plate. In this way, by sharing the external force through the light-transmitting cover plate and the display module, stress concentration can be avoided and the possibility of black spots or imprints on the screen can be reduced. Moreover, the area of the main body of the inner decorative part can be designed to be larger, and the area of the connection region with the display module can also be designed to be larger, which can increase the external force borne by the display module.

[0042] In a third aspect, a display device is further provided, which includes the screen assembly and the load-bearing member described in any technical solution of the first aspect. The load-bearing member is located on the back side of the screen, and the load-bearing member is also located on the side of the inner decorative member facing away from the outer decorative member. The surface of the inner decorative member facing away from the outer decorative member contacts the load-bearing member, or the distance from the inner decorative member to the load-bearing member is less than the difference between the first distance and the second distance.

[0043] In this way, when an external force acts on the outer decorative member, the outer decorative member transmits part of the external force to the inner decorative member, and further transmits it to the load-bearing member through the decorative member, and finally the load-bearing member bears the external force, avoiding discharging all the external force to the screen.

[0044] Optionally, the display device further includes a middle frame, which includes a middle plate and a frame provided at the edge of the middle plate. The middle plate forms the load-bearing member, and the edge of the screen is fixed to the frame. In this way, the external force is finally discharged to the middle frame. The middle frame has a relatively high structural strength and a strong load-bearing capacity, which can improve the impact resistance of the entire display device.

[0045] In a fourth aspect, a display device is further provided, which includes a housing, the screen assembly described in any technical solution of the second aspect, and a screen-side camera. The screen assembly is connected to the housing, the screen-side camera is disposed in the housing, and the light incident end of the screen-side camera faces the camera decorative member of the screen assembly.

[0046] Since the display device provided in this application includes the screen assembly described in any technical solution of the second aspect, the two can solve the same problems and achieve the same effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0089] On this basis, please refer to Figure 4 and Figure 5 , Figure 4 is Figure 3 a top view of the display device 100 in the folded state as shown, Figure 5 is Figure 4 a schematic cross-sectional structure diagram of a partial structure of the display device 100 along the A-A direction as shown. The screen assembly 20 further includes a camera decorative member 22, and the camera decorative member 22 is disposed on the screen 21 for decorating and protecting the screen-side camera 40.

[0090] As the user's requirements for the shooting quality of the screen-side camera 40 are getting higher and higher, the number of components integrated in the screen-side camera 40 is also increasing, such as at least one of an autofocus component, an anti-shake component, and a variable aperture component. In this way, the height of the screen-side camera 40 along the optical axis O is relatively large. Based on this, in order to protect the screen-side camera 40, please refer to Figure 4 and Figure 5 , the camera decorative member 22 can protrude from the display side of the screen 21 so as not to affect the thinness and lightness of the display device 100 and ensure the portability and feel of the display device 100.

[0091] However, since the camera decorative member 22 protrudes from the display side of the screen 21, in scenarios such as carrying, dropping, and transporting the display device 100, the camera decorative member 22 is easily impacted by an external force F. When this external force is transmitted to the screen 21 through the camera decorative member 22, the screen 21 is prone to problems such as black spots or imprints due to its low impact resistance.

[0092] To solve the above problems, please refer to Figure 6 and Figure 7 ,Figure 6 The top view of the display device 100 in a folded state provided by some other embodiments of the present application. Figure 7 is Figure 6 The partial cross-sectional structural schematic diagram of the display device 100 shown along the B-B direction. In this embodiment, the screen assembly 20 includes a screen 21 and a camera decorative member 22 disposed on the screen 21.

[0093] The screen 21 has a display side and a back side. The display side of the screen 21 refers to the side where the screen 21 displays videos or images, and a user can view the videos or images displayed on the screen 21 from this display side. The back side is opposite to the display side.

[0094] Please refer to Figure 7 and Figure 8 for reference. Figure 8 is Figure 6 The top view of the display device 100 shown after hiding the camera decorative member 22. The screen 21 is provided with at least one through hole a communicating the display side and the back side of the screen 21. In the figure, two through holes a are symmetrically distributed around the first mounting hole A as an example. The present application does not make special limitations on the number and position of the through holes a. The through hole a can be, but is not limited to, a circular hole, a square hole, an oval hole, a polygonal hole, a triangular hole, etc. The present application takes the through hole a as a circular hole for exemplary illustration.

[0095] Please refer to Figure 7 with emphasis. The camera decorative member 22 may include an outer decorative member 221, an inner decorative member 222, and at least one force-relieving boss 223.

[0096] At least a part of the outer decorative member 221 is located on the display side of the screen 21. That is to say, a part of the outer decorative member 221 may be located on the display side of the screen 21, or the whole may be located on the display side of the screen 21. Figure 7 Taking the whole of the outer decorative member 221 located on the display side of the screen 21 as an example for illustration, this should not be considered as a special limitation to the present application.

[0097] Based on this, for the convenience of the following description, the part of the outer decorative member 221 located on the display side of the screen 21 is defined as the outer decorative member main body 221a, and the outer decorative member main body 221a also covers the above at least one through hole a.

[0098] The outer decorative member main body 221a is disposed at an interval from the screen 21. That is to say, the distance between the outer decorative member main body 221a and the screen 21 is the first distance d1, and the first distance d1 is greater than 0. Wherein, the distance between the outer decorative member main body 221a and the screen 21 refers to the distance between the outer decorative member main body 221a and the screen 21 along the direction perpendicular to the screen 21 (that is, the Z-axis direction).

[0099] In some embodiments, a sealing structure or an adhesive structure may be provided in the gap between the outer decorative member body 221a and the screen 21. For example, please refer to Figure 7 , a first adhesive layer 225 may be provided in the gap between the outer decorative member body 221a and the screen 21. The first adhesive layer 225 includes, but is not limited to, back glue or dot glue. The first adhesive layer 225 bonds the outer decorative member 221 to the screen 21 to improve the connection stability of the outer decorative member 221 on the screen 21, and the first adhesive layer 225 can also prevent moisture and dust outside the display device from entering the inside of the display device along this gap, so as to play a role in waterproof sealing.

[0100] When an external force F acts on the camera decorative member 22, the outer decorative member 221 moves towards the screen 21 and presses the first adhesive layer 225, and a part of the external force F (such as the component force F1) can be transmitted to the screen 21 to impact the screen 21. The greater the component force F1, the greater the degree of damage to the screen 21, and the more likely it is to cause black spots or printing on the screen 21.

[0101] In other embodiments, a sealing structure, an adhesive structure, and other solid substances, paste substances, and liquid substances may not be provided in the gap between the outer decorative member body 221a and the screen 21. In this way, when the external force F acts on the camera decorative member 22, before the outer decorative member 221 moves to the position in contact with the screen 21, the outer decorative member 221 will not impact the screen 21.

[0102] At least a part of the inner decorative member 222 is located on the back side of the screen 21, that is to say, a part of the inner decorative member 222 may be located on the back side of the screen 21, or the whole may be located on the back side of the screen 21. Figure 7 Therefore, an example is given with a part of the inner decorative member 222 located on the back side of the screen 21, which should not be considered as a special limitation to this application.

[0103] Based on this, for the convenience of the following description, the part of the inner decorative member 222 located on the back side of the screen 21 is defined as the inner decorative member body 222a, and the inner decorative member body 222a also covers at least one of the above through holes a.

[0104] In some embodiments, please continue to refer to Figure 7 , at least one force-relieving boss 223 is provided on the inner decorative member body 222a. At least one force-relieving boss 223 may be integrally formed with the inner decorative member body 222a, or may be processed separately and assembled by means of connection methods such as welding, snap connection, and threaded connection. This application does not make specific limitations on this.

[0105] At least one force-relieving boss 223 is located between the outer decorative member body 221a and the inner decorative member body 222a, and at least one force-relieving boss 223 is received in the at least one through hole a.

[0106] The distance between at least one force-relieving boss 223 and the outer decorative member body 221a is a second distance d2, and the second distance d2 is greater than or equal to 0 mm. Wherein, the distance between at least one force-relieving boss 223 and the outer decorative member body 221a refers to the distance along the Z-axis direction between at least one force-relieving boss 223 and the outer decorative member body 221a.

[0107] The second distance d2 is less than the first distance d1, that is, at least one force-relieving boss 223 protrudes from the display surface of the screen 21, or at least one force-relieving boss 223 extends into the gap between the screen 21 and the outer decorative member body 221a. Wherein, the display surface of the screen 21 refers to the surface of the screen 21 facing the display side, and the display surface includes a display area opposite to the internal pixel points of the screen 21 and a non-display area opposite to the internal lead area.

[0108] In this way, please refer with emphasis to Figure 7 , when an external force F acts on the camera decorative member 22, the outer decorative member 221 moves towards the screen 21, and before contacting the screen 21, it contacts at least one force-relieving boss 223 of the inner decorative member 222, so as to release at least a part (such as the component force F2) of the external force F from at least one force-relieving boss 223 to the inner decorative member 222, and further release it through the inner decorative member 222. Thus, the inner decorative member 222 and the screen 21 share the impact force from the outer decorative member 221 together, which can reduce the impact force F1 of the outer decorative member 221 on the screen 21 and reduce the possibility of the screen 21 generating black spots or imprints. The part where the force-relieving boss 223 is located is the first force-relieving part.

[0109] In the above embodiment, please continue to refer to Figure 7 , the difference d (d = d1 - d2) between the first distance d1 and the second distance d2 is also the height by which the force-relieving boss 223 protrudes from the display surface of the screen 21. The outer decorative member 221 may generate slight vibrations under the impact of the external force F. In order to prevent the outer decorative member 221 from hitting the screen 21 during the vibration process, the force-relieving boss 223 needs to protrude from the display surface by a certain safety distance.

[0110] Based on this, in some embodiments, the difference d may be greater than or equal to 0.05 mm. Optionally, the difference d may be 0.05 mm, 0.08 mm, 0.1 mm, 0.15 mm, 0.18 mm or 0.2 mm. When the difference d is within this range, the height by which the force-relieving boss 223 protrudes from the display surface is relatively large, and it can effectively prevent the outer decorative member 221 from hitting the screen 21 under the action of the external force F.

[0111] The number of through holes a in the at least one through hole a described above can be one or more. Correspondingly, the number of force-relieving bosses 223 in the at least one force-relieving boss 223 can be one or more. One through hole a can accommodate one force-relieving boss 223, and one through hole a can also accommodate two or more force-relieving bosses 223. The present application does not make specific limitations on this.

[0112] Exemplarily, please refer to Figure 7 、 Figure 8 and Figure 9 , Figure 9 is Figure 6 the top view of the display device 100 shown in FIG. after hiding the outer decorative member 221. The number of through holes a in the at least one through hole a is two, and the number of force-relieving bosses 223 in the at least one force-relieving boss 223 is also two. The two force-relieving bosses 223 are respectively accommodated in the two through holes a, that is, one force-relieving boss 223 is accommodated in one through hole a. The set number of such through holes a is small, which can reduce the opening area on the screen 21 and ensure the structural strength of the screen 21.

[0113] In some embodiments, please refer to Figure 10 and Figure 11 , Figure 10 is Figure 7 the three-dimensional sectional view of the inner decorative member 222 in the display device 100 shown in FIG. Figure 11 is Figure 10 the three-dimensional sectional view of the assembly structure of the inner decorative member 222 and the screen 21 shown in FIG. The cross-sectional shapes and areas of the respective parts of the force-relieving boss 223 arranged along the Z-axis direction can be the same, and the cross-sectional area of the respective parts of the force-relieving boss 223 arranged along the Z-axis direction can be smaller than the area of the through hole a. Among them, the cross-section of the force-relieving boss 223 and its respective parts refers to the cross-section of the force-relieving boss 223 and its respective parts in a plane parallel to the display surface.

[0114] In this way, under the action of the external force F, the outer decorative member 221 impacts the force-relieving boss 223 and causes the force-relieving boss 223 to move along the axial direction of the through hole a, without impacting the inner wall of the through hole a, thereby further reducing the possibility of the screen 21 generating black spots or die marks.

[0115] In some embodiments, please continue to refer to Figure 7, the screen 21 includes a light-transmitting cover plate 211 and a display module 212 which are stacked. The material of the light-transmitting cover plate 211 includes but is not limited to glass, sapphire, polycarbonate (PC), a composite material of PC and glass fiber, acrylonitrile butadiene styrene plastic (ABS plastic), polymethyl methacrylate (PMMA), or a composite material of PC and PMMA. The display module 212 may include layer structures such as a display panel, a back film, a support layer, a polarizing layer, etc. The display side is located on the side of the light-transmitting cover plate 211 facing away from the display module 212, and the back side is located on the side of the display module 212 facing away from the light-transmitting cover plate 211.

[0116] Based on this, optionally, please refer to Figure 7 , at least one of the above through holes a may be provided in the light-transmitting cover plate 211. A first avoidance hole 212a is provided on the display module 212. The first avoidance hole 212a is at least opposite to and communicated with at least one of the above through holes a. The inner decoration member main body 222a may be accommodated in the first avoidance hole 212a.

[0117] In this way, the inner decoration member main body 222a is sunk in the first avoidance hole 212a, which can prevent the height of the inner decoration member main body 222a protruding from the back side from being too high and affecting the structural compactness of the whole machine.

[0118] In some embodiments, please refer back to Figures 7 - 9 , the screen 21 may further be provided with a first mounting hole A communicating the display side and the back side for accommodating the screen-side camera 40. The shape of the first mounting hole A includes but is not limited to circular, square, oval, polygonal, triangular, rhombic, etc. In this application, the shape of the first mounting hole A is circular for exemplary illustration.

[0119] The outer decoration member 221 and the inner decoration member 222 are connected at least via the first mounting hole A. That is to say, the outer decoration member 221 is connected to the inner decoration member 222, and the part of the outer decoration member 221 for connecting to the inner decoration member 222 and / or the part of the inner decoration member 222 for connecting to the outer decoration member 222 are accommodated in the first mounting hole A.

[0120] Exemplarily, please refer to Figure 7 、 Figure 9 and Figure 11 , the inner decoration member 222 may include a first connecting boss 222b provided on the inner decoration member 222. The first connecting boss 222b is accommodated in the first mounting hole A, and the outer decoration member main body 221a is connected to the first connecting boss 222b.

[0121] In this way, the first connecting boss 222b forms the part on the inner decorative member 222 for connecting with the outer decorative member 222. There is no need to provide a boss on the outer decorative member 221, so the surface profile is simple, and the processing difficulty of the outer decorative member 221 can be reduced.

[0122] In the above example, please continue to refer to Figure 7 and Figure 12 , Figure 12 For Figure 7 the cross-sectional view of the assembly structure of the outer decorative member 221 and the inner decorative member 222 in the display device 100 shown in the figure, a second adhesive layer 226 may be provided between the outer decorative member main body 221a and the first connecting boss 222b. The second adhesive layer 226 includes but is not limited to back glue or dot glue. The outer decorative member main body 221a is bonded to the first connecting boss 222b by means of the second adhesive layer 226. In this way, there is no need to drill holes in the outer decorative member 221 and the inner decorative member 222, and the structural strength and integrity can be ensured.

[0123] In other embodiments, the outer decorative member main body 221a and the first connecting boss 222b may also be connected by means of connecting members such as threaded connecting members and snap connectors, or may be connected as a whole by means of integral molding, or may be fixedly connected by means of processes such as welding and pressing. For example, please refer to Figure 13 , Figure 13 which is the cross-sectional view of the assembly structure of the outer decorative member 221 and the inner decorative member 222 in the display device 100 provided in some other embodiments of the present application. In this embodiment, the outer decorative member 221 and the inner decorative member 222 are fixedly connected by means of processes such as welding and pressing.

[0124] In some other examples, please refer to Figure 14 , Figure 14 which is the schematic cross-sectional structure diagram of the display device 100 provided in some other embodiments of the present application. The outer decorative member 221 includes a second connecting boss 221b. The second connecting boss 221b is received in the first mounting hole A and is connected to the inner decorative member main body 222a.

[0125] In this way, the second connecting boss 221b forms the part on the outer decorative member 221 for connecting with the inner decorative member 222. There is no need to provide a boss on the inner decorative member 222, so the surface profile is simple, and the processing difficulty of the inner decorative member 222 can be reduced.

[0126] In the above embodiment, the second connecting boss 221b and the inner decorative member 222 may be bonded and fixed by means of the second adhesive layer 226, or may be connected by means of connecting members such as threaded connecting members and snap connectors, or may be formed as a whole by means of integral molding. The present application does not make specific limitations on this.

[0127] In some other examples, please refer toFigure 15 , Figure 15 This is a schematic cross-sectional structure diagram of the display device 100 provided by some other embodiments of the present application. The inner decorative member 222 includes a first connecting boss 222b, and the outer decorative member 221 includes a second connecting boss 221b. Both the first connecting boss 222b and the second connecting boss 221b are received in the first mounting hole A, and the first connecting boss 222b is connected to the second connecting boss 221b.

[0128] In this way, the first connecting boss 222b forms a part of the inner decorative member 222 for connecting with the outer decorative member 222, and the second connecting boss 221b forms a part of the outer decorative member 221 for connecting with the inner decorative member 222. The set heights of the first connecting boss 222b and the second connecting boss 221b are relatively small. During the assembly process, both the first connecting boss 222b and the second connecting boss 221b can cooperate with the first mounting hole A to limit the outer decorative member 221 and the inner decorative member 222, ensuring the assembly accuracy.

[0129] Similarly, in the above embodiment, the first connecting boss 222b and the second connecting boss 221b can be bonded and fixed by means of the second adhesive layer 226, or can be connected by means of structural members such as threaded connectors and snap connectors, or can be formed into an integral body by means of integral molding. The present application does not make specific limitations on this.

[0130] The outer decorative member 221 and the inner decorative member 222 are connected via the first mounting hole A. At the same time, the outer decorative member 221 and the inner decorative member 222 respectively limit the screen 21 from the display side and the back side, thereby connecting the camera decorative member 22 to the screen 21. This structure is simple and easy to implement.

[0131] Moreover, the connection part of the outer decorative member 221 and the inner decorative member 222 in the first mounting hole A forms a second force-relieving part. When an external force F acts on the camera decorative member 22, please refer to Figure 7 . In addition to being able to transfer a part of the component force of the external force F (that is, the component force F2) from the above-mentioned first force-relieving part to the inner decorative member 222, the outer decorative member 221 can also transfer a part of the component force of the external force F (such as the component force F3) from this second force-relieving part to the inner decorative member 222. Thus, the external force released to the inner decorative member 222 can be increased, and the impact force F1 released from the outer decorative member 221 to the screen 21 can be reduced, thereby further reducing the possibility of black spots or imprinting on the screen 21.

[0132] In other embodiments, the outer decorative member 221 and the inner decorative member 222 can also be respectively located on the display side and the back side of the screen 21 and be connected by means of threaded connectors or snap connectors penetrating the screen 21. The present application does not make specific limitations on this.

[0133] For ease of description, the following embodiments are further described on the basis that the interior decorative member 222 shown in Figure 7 includes a first connecting boss 222b, and the outer decorative member main body 221a is connected to the first connecting boss 222b. Of course, the following embodiments can also be combined with Figure 14 or Figure 15 the embodiments shown. The present application does not make specific limitations on this.

[0134] Based on any of the above embodiments, please refer back to Figure 7 , the outer decorative member 221 is provided with a first light-passing hole N1, and the interior decorative member 222 is provided with a second light-passing hole N2. The first light-passing hole N1 and the second light-passing hole N2 are opposite and communicate with each other.

[0135] Based on this, the camera decorative member 22 further includes a light-transmitting member 224. The light-transmitting member 224 is disposed on the side of the outer decorative member 221 facing away from the interior decorative member 222, and the light-transmitting member 224 covers the first light-passing hole N1. The light-incident end of the screen-side camera 40 faces the second light-passing hole N2, or is accommodated in the first light-passing hole N1 and the second light-passing hole N2.

[0136] The image light beam outside the display device 100 can pass through the light-transmitting member 224 and enter the screen-side camera 40.

[0137] The material of the light-transmitting member 224 includes, but is not limited to, glass, sapphire, polycarbonate (PC), a composite material of PC and glass fiber, acrylonitrile butadiene styrene plastic (ABS plastic), polymethyl methacrylate (PMMA), or a composite material of PC and PMMA. The present application does not make specific limitations on this.

[0138] In some embodiments, please refer to Figure 7 , a third adhesive layer 227 may be provided between the light-transmitting member 224 and the outer decorative member 221. The third adhesive layer 227 includes, but is not limited to, dot gluing or back gluing. The light-transmitting member 224 is bonded to the outer decorative member 221 by means of the third adhesive layer 227. In some embodiments, the third adhesive layer 227 may be distributed in a ring shape, and the first light-passing hole N1 is located in the area surrounded by the third adhesive layer 227.

[0139] In this way, the third adhesive layer 227 can prevent moisture outside the display device 100 from entering the first light-passing hole N1 along the gap between the light-transmitting member 224 and the outer decorative member 221, thereby playing a role in waterproof sealing.

[0140] In some embodiments, please refer to Figure 7 and Figure 8At least one through hole a may be located on the outer peripheral side of the first mounting hole A, where the outer peripheral side of the first mounting hole A refers to the side of the inner wall surface of the first mounting hole A that is opposite to the central axis of the first mounting hole A.

[0141] In this way, the through hole a does not overlap with the first mounting hole A, the first force release part does not overlap with the second force release part, and part of the impact force received by the outer decorative component 222 can be released to the inner decorative component 222 from two different positions, the first force release part and the second force release part, thereby improving the force release efficiency.

[0142] Of course, in other embodiments, at least one through hole a may also overlap with the first mounting hole A, that is, at least one through hole a is the same through hole as the first mounting hole A. In this way, the area occupied by the camera decorative element 22 on the screen 21 can be designed to be smaller, and the size of the camera decorative element 22 can be designed to be smaller.

[0143] The following embodiments are further described on the basis that at least one through hole a is located on the outer peripheral side of the first mounting hole A.

[0144] See also Figure 8 , the two through holes a are located on the outer peripheral side of the first mounting hole A, and the two through holes a are symmetrically distributed relative to the central axis of the first mounting hole A. In this way, the number of the first force release parts is two, and the two first force release parts are respectively located on the opposite sides of the second force release part, which can ensure the stability of the force release.

[0145] In some other embodiments, see Figure 16 , Figure 16 A top view of the display device 100 provided in some other embodiments of the present application after hiding the outer decorative part 221. In this embodiment, the number of through holes a in the at least one through hole a is three, and the three through holes a are evenly distributed along the circumference of the first mounting hole A. The circumference of the first mounting hole A refers to the direction around the central axis of the first mounting hole A. The three through holes a are evenly distributed along the circumference of the first mounting hole A means that along the circumference of the first mounting hole A, the central angles of any two adjacent through holes a relative to the central axis of the first mounting hole A are approximately equal, and the distances from the three through holes a to the central axis of the first mounting hole A are also approximately equal.

[0146] Based on this, the number of the force relief bosses 223 in the at least one force relief boss 223 is also three, and the three force relief bosses 223 are respectively accommodated in the three through holes a.

[0147] In this way, when the external force F acts on the camera decoration 22, the three force release bosses 223 can provide stable support for the outer decoration 221 to prevent the outer decoration 221 from tilting when the external force F is eccentric, thereby avoiding the outer decoration 221 from impacting the screen 21 as much as possible.

[0148] Of course, in other embodiments, the three through holes a may also be non-uniformly distributed along the circumferential direction of the first mounting hole A. That is to say, along the circumferential direction of the first mounting hole A, the central angles of two adjacent through holes a with respect to the central axis of the first mounting hole A are not equal, and / or the distances from the three through holes a to the central axis of the first mounting hole A are not equal.

[0149] In some embodiments, please refer to Figure 8 and Figure 16 , at least one of the above through holes a and the first mounting hole A may be arranged at intervals. In this way, the first force-relieving part and the second force-relieving part are arranged at intervals, which can avoid the concentration of the force-relieving parts, prevent the outer decorative member 221 from tilting under the action of an external force, and thus avoid the outer decorative member 221 from impacting the screen 21.

[0150] In still other embodiments, please refer to Figure 17 , Figure 17 which is a top view of the display device 100 provided in still other embodiments of the present application after hiding the outer decorative member 221. In this embodiment, at least one through hole a communicates with the first mounting hole A.

[0151] In this way, the distance between at least one through hole a and the first mounting hole A can be designed to be shorter, which can reduce the area of the occupied region of at least one through hole a and the first mounting hole A on the screen 21, is beneficial to reducing the size of the camera decorative member 22, and increasing the screen-to-body ratio of the screen assembly 20.

[0152] In some embodiments, please refer back to Figure 7 , the first adhesive layer 225 may be annular, and the first mounting hole A and at least one through hole a may be located in the region surrounded by the first adhesive layer 225.

[0153] In this way, waterproof sealing can be achieved by means of the first adhesive layer 225 to prevent moisture outside the display device 100 from entering the through hole a or the first mounting hole A through the gap between the outer decorative member main body 221a and the screen 21.

[0154] In some embodiments, please refer to Figure 18 , Figure 18 which is a top view of the display device 100 provided in still other embodiments of the present application after hiding the outer decorative member 221. In this embodiment, the screen 21 is further provided with a second mounting hole B communicating the display side and the back side, and the second mounting hole B and the first mounting hole A are arranged at intervals.

[0155] Based on this, the outer decorative part 221 and the inner decorative part 222 are also connected via the second mounting hole B. Optionally, the implementation method of the connection between the outer decorative part 221 and the inner decorative part 222 via the second mounting hole B can be implemented with reference to the implementation method of the connection between the outer decorative part 221 and the inner decorative part 222 via the first mounting hole A, which will not be repeated here.

[0156] In this way, the connection part between the outer decorative part 221 and the inner decorative part 222 in the second mounting hole B is the third force release part. When the external force F acts on the camera decorative part 22, the outer decorative part 221 can transfer a part of the component of the external force F (such as component F4) from the third force release part to the inner decorative part 222. The third force release part cooperates with the aforementioned first force release part and second force release part to release more external force to the inner decorative part 222, which can further reduce the impact force released from the outer decorative part 221 to the screen 21, thereby further reducing the possibility of black spots or molds on the screen 21.

[0157] On the basis of the above, please continue to refer to Figure 18 , at least one through hole a is located between the first mounting hole A and the second mounting hole B. By means of the cooperation between the first force release part in the at least one through hole a and the second force release part and the third force release part, the impact force released from the outer decorative part 221 to the screen 21 can be effectively reduced, and there is no need to set additional through holes a at other positions, which is conducive to reducing the area of ​​the opening area on the screen 21 and reducing the size of the camera decorative part 22.

[0158] In some embodiments, please refer to Figure 18 , define the plane passing through the central axis of the first mounting hole A and the central axis of the second mounting hole B as the reference plane. Based on this, the number of through holes a in at least one through hole a can be one, and the one through hole a is a long hole, and a long hole means that the size in one direction is larger than the size in another direction, and the one direction and the other direction are both parallel to the screen 21, and the one direction is perpendicular to the other direction, and the direction with the larger size is also the length direction of the long hole. Optionally, the length direction of the long hole can be perpendicular to the reference plane.

[0159] On the basis of the above, the cross-sectional shape of the force relief boss 223 is a long strip, the force relief boss 223 is accommodated in the long hole, and the length direction of the cross-sectional shape of the force relief boss 223 is consistent with the length direction of the long hole. In this way, when the external force F acts on the camera decorative part 22, the support range of the force relief boss 223 on the external decorative part 221 is relatively large, which can improve the force relief efficiency.

[0160] Based on any of the above embodiments, the materials of the outer decorative member 221 and the inner decorative member 222 can be metals such as stainless steel, aluminum alloy, copper alloy, magnesium alloy or titanium alloy, or plastics such as polycarbonate (PC), PC + glass fiber and acrylonitrile butadiene styrene plastic (ABS plastic), or other materials such as ceramics.

[0161] In some embodiments, the outer decorative member 221 is a metal member. The texture of the metal is good, which can improve the appearance performance of the display device 100, and the hardness of the metal is large, which can improve the anti-deformation ability of the outer decorative member 221. The inner decorative member 222 is a plastic member. The plastic can adopt an integral injection molding process to form a complex surface, and the molding difficulty is low. Moreover, the cost and density of the plastic material are small, which can reduce the cost and weight of the inner decorative member 222.

[0162] In order to further release the external force transmitted to the inner decorative member 222, in some embodiments, please refer back to Figure 7 , the display device 100 may further include a load-bearing member 50. The material of the load-bearing member 50 can be metals such as stainless steel, aluminum alloy, and magnesium aluminum alloy, or plastics such as PC and mylar, or other materials such as ceramics. Based on this, the surface of the inner decorative member 222 facing away from the outer decorative member 221 can be in contact with the load-bearing member 50, or the distance from the inner decorative member 222 to the load-bearing member 50 is less than the difference between the first spacing d1 and the second spacing d2.

[0163] In this way, when an external force acts on the outer decorative member 221, the outer decorative member 221 transmits part of the external force to the inner decorative member 222, and further transmits it to the load-bearing member 50 through the decorative member 222. Finally, the load-bearing member 50 bears the external force, avoiding releasing all the external force to the screen 21.

[0164] Optionally, the load-bearing member 50 can be formed by a part of the first housing 31. Exemplarily, please continue to refer to Figure 7 , the first housing 31 includes a middle frame 311. The middle frame 311 is located between the inner folding screen 10 and the screen assembly 20. The middle frame 311 serves as the supporting "skeleton" of the display device 100. The middle frame 311 includes a middle plate 311a and a border (not shown in the figure) provided at the edge of the middle plate 311a. The middle plate 311a forms the load-bearing member 50. The inner folding screen 10 is located on the side of the middle plate 311a facing away from the screen assembly 20 and is fixed to the middle plate 311a, and the screen 21 of the screen assembly 20 is fixed to the border. In this way, the external force is finally released to the middle frame 311. The middle frame 311 has a large structural strength and a strong load-bearing capacity, which can improve the anti-impact performance of the whole display device 100.

[0165] Of course, in other embodiments, the load-bearing member 50 may also be independent of the first housing 31. For example, the load-bearing member 50 may be a spacer disposed between the inner decorative member 222 and the middle frame 311, and the present application does not make specific limitations thereto.

[0166] The above embodiments are described by way of example with the force-relieving boss 223 disposed on the inner decorative member main body 222a. In other embodiments, the above force-relieving boss 223 may also be disposed on the outer decorative member main body 221a.

[0167] Exemplarily, please refer to Figure 19 , Figure 19 which is a schematic cross-sectional structure diagram of the display device 100 provided by some other embodiments of the present application. In this embodiment, at least one force-relieving boss 223 is disposed on the outer decorative member main body 221a. At least one force-relieving boss 223 may be integrally formed with the outer decorative member main body 221a, or may be processed separately and assembled by means of connection methods such as welding, snap connection, and screw connection. The present application does not make specific limitations thereto.

[0168] The distance between at least one force-relieving boss 223 and the inner decorative member main body 222a is a second distance d2, and the second distance d2 is greater than or equal to 0 mm. The second distance d2 is less than the first distance d1.

[0169] In this way, please refer to Figure 19 , when an external force F acts on the camera decorative member 22, the outer decorative member 221 moves toward the screen 21, and before the outer decorative member 221 contacts the screen 21, at least one force-relieving boss 223 contacts the inner decorative member main body 22a, so as to release at least a part (such as the component force F2) of the external force F from at least one force-relieving boss 223 to the inner decorative member 222, and further release it through the inner decorative member 222. Thus, the inner decorative member 222 and the screen 21 also share the impact force from the outer decorative member 221, which can reduce the impact force of the outer decorative member 221 on the screen 21 and reduce the possibility of black spots or printing on the screen 21.

[0170] Please refer to Figure 20 , Figure 20 which is a schematic cross-sectional structure diagram of the display device 100 provided by some other embodiments of the present application. In this embodiment, the screen 21 is provided with a first mounting hole A communicating the display side and the back side.

[0171] The camera decorative member 22 includes an outer decorative member 221 and an inner decorative member 222.

[0172] At least a part of the outer decorative member 221 is located on the display side of the screen 21. For the convenience of the following description, the part of the outer decorative member 221 located on the display side of the screen 21 is defined as the outer decorative member main body 221a.

[0173] At least a part of the inner decorative member 222 is located on the back side of the screen 21. For the convenience of the following description, the part of the inner decorative member 222 located on the back side of the screen 21 is defined as the inner decorative member main body 222a.

[0174] The outer decorative member 221 and the inner decorative member 222 are connected via the first mounting hole A. Optionally, the implementation manner of connecting the outer decorative member 221 and the inner decorative member 222 via the first mounting hole A may be the same as the implementation manner of connecting the outer decorative member 221 and the inner decorative member 222 via the first mounting hole A described in any of the foregoing embodiments, and will not be elaborated herein.

[0175] The outer decorative member main body 221a is connected to the display surface of the screen 21. The display surface of the screen 21 refers to the surface of the screen 21 facing the display side. Optionally, a first adhesive layer 225 may be provided between the outer decorative member main body 221a and the display surface of the screen 21, and the outer decorative member main body 221a is adhered to the display surface of the screen 21 by means of the first adhesive layer 225.

[0176] The inner decorative member main body 222a is connected to the back of the screen 21. The back of the screen 21 refers to the surface of the screen 21 facing the back side. Optionally, a fourth adhesive layer 228 may be provided between the inner decorative member main body and the back of the screen 21. The fourth adhesive layer 228 includes but is not limited to back glue or dot glue. The inner decorative member main body is adhered to the back of the screen 21 by means of the fourth adhesive layer 228.

[0177] In this way, please refer to Figure 20 , when an external force F acts on the camera decorative member 22, the outer decorative member 221 moves towards the screen 21, and a part of the external force F (such as the component force F1) is released from the display surface to the screen 21, and another part (such as the component force F4) is released from the back surface to the screen 21. Thus, the external force F can be shared by the display surface and the back surface of the screen 21, avoiding stress concentration and reducing the possibility of black spots or mold marks on the screen 21.

[0178] In some embodiments, please refer to Figure 20 , the screen 21 includes a light-transmitting cover plate 211 and a display module 212 arranged in a stacked manner. The first mounting hole A is provided in the light-transmitting cover plate 211. The display module 212 may be provided with a second avoidance hole 212b, the second avoidance hole 212b is opposite to and communicated with the first mounting hole A, and the area of the second avoidance hole 212b is larger than the area of the first mounting hole A.

[0179] Wherein, the area of the second avoidance hole 212b refers to the projected area of the second avoidance hole 212b on the light-transmitting cover plate 211, and the area of the first mounting hole A refers to the occupied area or the projected area of the first mounting hole A on the light-transmitting cover plate 211.

[0180] On the basis described above, a partial area of the back surface of the screen 21 is formed by the surface area of the light-transmitting cover plate 211 facing the second avoidance hole 212b. The inner decoration member main body 222a can be accommodated in the second avoidance hole 212b, and the inner decoration member main body 222a is connected to the surface area of the light-transmitting cover plate 211 facing the second avoidance hole 212b.

[0181] Among them, the surface area of the light-transmitting cover plate 211 facing the second avoidance hole 212b refers to the partial area between the inner wall surface of the first mounting hole A and the inner wall surface of the second avoidance hole 212b on the surface of the light-transmitting cover plate 211 facing the second avoidance hole 212b.

[0182] In this way, by sharing the external force F through the display surface and the back surface of the light-transmitting cover plate 211, stress concentration can be avoided, and damage to the display module 212 can be prevented. Moreover, since the inner decoration member main body 222a is sunk in the second avoidance hole 212b, the height of the inner decoration member main body 222a protruding from the back surface side can be avoided from being too high, which affects the structural compactness of the whole machine.

[0183] In some other embodiments, please refer to Figure 21 , Figure 21 which is a schematic cross-sectional structure diagram of the display device 100 provided by some other embodiments of the present application. In this embodiment, at least a partial area of the back surface is formed by the surface of the display module 212 facing away from the light-transmitting cover plate 211.
