Description

Technical Field

[0001] This application belongs to the field of display technology, and more specifically, relates to a connection structure and a display device. Background Technology

[0002] Generally speaking, the screen-to-body ratio of a display device is an important factor for users when choosing a specific product. A narrower black border on the display surface results in a better user experience.

[0003] For example, such as Figure 1 As shown, in existing mobile phone designs, the display assembly 11' is housed within the mid-frame 12'. When assembling the display assembly 11' and the mid-frame 12', their assembly relationship must meet preset assembly requirements. These requirements are: after assembly, a 0.4mm gap is reserved between the inner wall of the mid-frame 12' and the outer wall of the display module 111', which are opposite each other along the first direction of the mobile phone. Under these conditions, the gap between the inner wall of the mid-frame 12' and the outer wall of the panel 112', which are opposite each other along the first direction of the mobile phone, can be accommodated by a dispensing process to accommodate a sufficient amount of adhesive 13', thereby bonding the display assembly 11' and the mid-frame 12'. However, this adhesive cannot reach the 0.4mm gap, therefore the 0.4mm gap remains unfilled.

[0004] To ensure the bonding strength between the display assembly 11' and the mid-frame 12', the gap between the inner wall of the mid-frame 12' and the outer wall of the panel 112' cannot be reduced, nor can the 0.4mm gap between the inner wall of the mid-frame 112' and the outer wall of the display module 111' be reduced. Consequently, the projection of the entire gap between the mid-frame 12' and the display assembly 11' onto the display surface along the thickness direction of the phone forms a black border. Combined with the black border itself formed by the edges of the display module 111', the overall size of the black border appearing on the display surface is relatively large, preventing the phone from achieving its maximum screen-to-body ratio and thus hindering a better user experience. Summary of the Invention

[0005] The purpose of this application is to provide a connection structure and display device to solve the technical problem that the large black border size of the existing connection structure with display screen components and mid-frame combination affects the user experience.

[0006] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0007] A connection structure is provided, including a display assembly, a mid-frame, and a first adhesive material;

[0008] The display assembly includes a display module and a panel integrated with the display module;

[0009] The middle frame has a bottom wall extending along a first direction and a first side wall connected to the bottom wall and extending along a second direction, and a step wall connected to the first side wall and extending along the first direction, the first direction being arranged transversely to the second direction; wherein the bottom wall, the display module and the panel are arranged along the second direction;

[0010] The display module has a first bottom surface extending along the first direction and opposite to the bottom wall along the second direction, and a first side surface connected to the first bottom surface and extending along the second direction, and the panel has a second bottom surface connected to the first side surface and extending along the first direction;

[0011] The first side surface and the first side wall are arranged opposite and spaced apart along the first direction, and the part of the bottom wall between the first side surface and the first side wall is arranged opposite and spaced apart from the second bottom surface along the second direction, and the first adhesive is arranged between the first side surface, the first side wall, the second bottom surface and the part;

[0012] The first adhesive is bonded to at least one of the first side surface and the second bottom surface, and the first adhesive is bonded to at least one of the first side wall and the part.

[0013] In some embodiments, the first adhesive is bonded to the first side wall and the part, and the first adhesive is bonded to the first side surface.

[0014] In some embodiments, the connecting structure further comprises a second adhesive; the panel has a step surface extending along the first direction and connected to the second bottom surface, the step surface and the step wall are arranged opposite and spaced apart along the second direction, and the second adhesive is arranged between the step surface and the step wall and bonds the step surface and the step wall.

[0015] In some embodiments, the connecting structure further comprises a third adhesive; the panel has a second side surface extending along the second direction and connected to the step surface, and the middle frame has a second side wall extending along the second direction and connected to the step wall, the second side surface and the second side wall are spaced apart along the first direction, and the third adhesive is arranged between the second side surface and the second side wall and bonds the second side surface and the second side wall.

[0016] In some embodiments, the first direction and the second direction are perpendicular to each other; the first direction is directed from the center of the connecting structure to the edge of the connecting structure, and the second direction is the thickness direction of the connecting structure.

[0017] In some embodiments, the spacing dimension of the first side surface and the first side wall along the first direction is 0.2mm.

[0018] In some embodiments, the first adhesive material is an annular structure continuously extending along the circumference of the connecting structure.

[0019] In some embodiments, the first adhesive material comprises a plurality of adhesive units arranged along the circumference of the connecting structure.

[0020] In some embodiments, the first adhesive material is pre-prepared on the first side surface and the portion before the assembly of the display screen assembly and the middle frame, and is bonded on the first side wall and the portion during the assembly of the display screen assembly and the middle frame.

[0021] Alternatively, the first adhesive material is pre-prepared on the first side wall and the portion before the assembly of the display screen assembly and the middle frame, and is bonded on the first side surface and the portion during the assembly of the display screen assembly and the middle frame.

[0022] The connecting structure provided by the present application has the following advantages:

[0023] Compared with the prior art, in the connecting structure provided by the present application, the first side surface of the display module and the first side wall of the middle frame are oppositely arranged along the first direction and are spaced apart, and the portion of the bottom wall of the middle frame located between the first side surface and the first side wall and the second bottom surface of the panel are oppositely arranged along the second direction and are spaced apart, so that a space is formed between the first side surface, the first side wall, the second bottom surface and the portion of the bottom wall, and the first adhesive material is arranged in the space.

[0024] The space is used to accommodate the first adhesive material, and the first adhesive material bonds the middle frame and the display screen assembly. By adding the first adhesive material, the amount of the original adhesive material between the middle frame and the display screen assembly can be reduced, so that the size of the space where the original adhesive material is located can be reduced, and the width size of the black border of the connecting structure in the first direction can be reduced, thereby reducing the width size of the black border.

[0025] More importantly, the present application can allow the overall size of the middle frame in the first direction to be reduced, and the distance between the display screen assembly and the middle frame in the first direction after the assembly of the display screen assembly and the middle frame can be reduced, including allowing the size of the first side surface and the first side wall in the first direction to be reduced, for example, from the original 0.4mm to 0.2mm, which means that the first side wall of the middle frame in the first direction is recessed towards the first side surface by 0.2mm. The display screen assembly is provided with a first side surface on each of the opposite sides in the first direction, and the middle frame is provided with a first side wall on each of the opposite sides in the first direction. For the connecting structure as a whole, each of the opposite sides in the first direction is recessed by 0.2mm, that is, the width of the black border on each of the opposite sides can be reduced by 0.2mm, and the total reduction is 0.4mm.

[0026] It should be noted that in the field of display devices, affected by the precision of manufacturing equipment, if the connecting structure is not changed, it is also necessary to ensure good bonding strength, and it is relatively difficult to reduce the black border width by 0.1mm. Through the connecting structure of the present application, a reduction of 0.2mm is achieved on one side, so that the black border width can be reduced by 0.4mm from the opposite sides, thereby achieving the purpose of significantly improving the screen ratio of the connecting structure. In addition, the first adhesive material is configured in the above-mentioned space by pre-fabricating before assembling the display screen assembly and the middle frame, thereby solving the problem that the glue cannot reach the above-mentioned space and thus the above-mentioned space cannot be utilized.

[0027] Another purpose of the embodiment of the present application is to provide a display device comprising the connecting structure as described above.

[0028] The display device provided by the embodiment of the present application has the beneficial effects of the connecting structure provided by the embodiment of the present application compared with the prior art, which will not be described here. BRIEF DESCRIPTION OF DRAWINGS

[0053] Referring to Figures 2 to 7 The connecting structure 1000 provided by the embodiments of the present application includes a display screen assembly 100, a middle frame 200 and a first adhesive material 300. The display screen assembly 100 includes a display module 101 and a panel 102 integrally arranged with the display module 101.

[0054] The middle frame 200 has a bottom wall 201 extending along a first direction, a first side wall 202 connected to the bottom wall 201 and extending along a second direction, and a stepped wall 203 connected to the first side wall 202 and extending along the first direction, the first direction and the second direction being arranged in cross. Wherein, the bottom wall 201, the display module 101 and the panel 102 are arranged along the second direction.

[0055] The display module 101 has a first bottom surface 1011 extending along the first direction and opposite to the bottom wall 201 along the second direction, and a first side surface 1012 connected to the first bottom surface 1011 and extending along the second direction, and the panel 102 has a second bottom surface 1021 connected to the first side surface 1012 and extending along the first direction. The first side surface 1012 and the first side wall 202 are opposite and spaced apart along the first direction, and the portion 2011 of the bottom wall 201 between the first side surface 1012 and the first side wall 202 is opposite and spaced apart from the second bottom surface 1021 along the second direction, and the first glue material 300 is arranged between the first side surface 1012, the first side wall 202, the second bottom surface 1021 and the portion 2011.

[0056] The first glue material 300 is bonded to at least one of the first side surface 1012 and the second bottom surface 1021, and the first glue material 300 is bonded to at least one of the first side wall 202 and the portion 2011 of the bottom wall 201.

[0057] In some embodiments, the first glue material 300 is pre-prepared on at least one of the first side surface 1012 and the second bottom surface 1021 before the display screen assembly 100 and the middle frame 200 are assembled, and is bonded to at least one of the first side wall 202 and the portion 2011 when the display screen assembly 100 and the middle frame 200 are assembled; or, the first glue material 300 is pre-prepared on at least one of the first side wall 202 and the portion 2011 before the display screen assembly 100 and the middle frame 200 are assembled, and is bonded to at least one of the first side surface 1012 and the second bottom surface 1021 when the display screen assembly 100 and the middle frame 200 are assembled.

[0058] The panel 102 refers to the portion 2011 of the display screen assembly 100 which is integrated with the display module 101 and displays the picture through the side away from the display module 101, and the side of the picture is the display surface. The edge of the panel 102 generally extends beyond the display module 101 along the first direction, and the black border of the display surface is formed in the edge area of the panel 102, and the black border has a width along the first direction.

[0059] In some embodiments, the panel 102 includes, but is not limited to, a flexible substrate, an anode layer, a hole transport layer, an organic light-emitting layer, an electron transport layer, a metal cathode layer, and an encapsulation film layer arranged in layers, wherein the flexible substrate is closest to the display module 101, and the panel 102 can be integrated with the display module 101 through the flexible substrate.

[0060] As Figure 8 and Figure 9As shown, the display device is placed in a three-dimensional coordinate system, wherein the X direction is the width direction of the display device, the Y direction is the height direction of the display device, and the Z direction is the thickness direction of the display device, the first direction refers to the direction from the center to the edge in the X direction or the direction from the center to the edge in the Y direction, and the second direction refers to the direction from the back to the front in the Z direction.

[0061] When the display surface is a flat screen, the black border is formed in the edge area of the flat screen, the first direction is from the center of the display device 2000 to the edge of the display device 2000, the second direction is the thickness direction of the display device 2000, and the first direction and the second direction are perpendicular to each other.

[0062] When the display surface is a curved screen, the black border is formed in the edge area of the curved part of the display surface, the first direction has a certain inclination angle with the direction from the center of the display device 2000 to the edge of the display device 2000, the second direction is the thickness direction of the display device 2000, and the first direction and the second direction are at a non-perpendicular angle.

[0063] The middle frame 200 refers to a frame structure for accommodating and connecting the display screen assembly 100. Other frame structures can be further arranged outside the middle frame 200 to accommodate the middle frame 200.

[0064] In some embodiments, the first adhesive material 300 can be prepared (i.e., prefabricated) on the first side surface 1012 before the display screen assembly 100 and the middle frame 200 are assembled, and the first adhesive material 300 can be prefabricated on the second bottom surface 1021, or the first adhesive material 300 can be prefabricated on the first side surface 1012 and the second bottom surface 1021. When the display screen assembly 100 and the middle frame 200 are assembled, the first adhesive material 300 can be bonded to the first side wall 202, or bonded to part 2011 of the bottom wall 201, or bonded to the first side wall 202 and part 2011 of the bottom wall 201.

[0065] In some embodiments, the first adhesive material 300 can be prefabricated on the first side wall 202 before the display screen assembly 100 and the middle frame 200 are assembled. Alternatively, the first adhesive material 300 can also be prefabricated on part 2011 of the bottom wall 201, or prefabricated on the first side wall 202 and part 2011 of the bottom wall 201 before the display screen assembly 100 and the middle frame 200 are assembled. During the assembly of the display screen assembly 100 and the middle frame 200, the first adhesive material 300 can be bonded to the first side surface 1012, bonded to the second bottom surface 1021, or bonded to the first side surface 1012 and the second bottom surface 1021.

[0066] In some embodiments, before the display screen assembly 100 and the middle frame 200 are assembled, whether the first adhesive 300 is pre-prepared on the display screen assembly 100 or the middle frame 200, at least the first adhesive 300 is bonded to the first side surface 1012 and the first side wall 202 when the display screen assembly 100 and the middle frame 200 are assembled, so as to limit the relative position of the first side surface 1012 and the first side wall 202 in the first direction, thereby limiting the relative position of the display screen assembly 100 and the middle frame 200 in the first direction. For example, in some embodiments, the first adhesive 300 is connected to the first side surface 1012 and the first side wall 202 on both sides in the first direction, and the first adhesive 300 is arranged apart from the second bottom surface 1021 on one side in the second direction and connected to the part 2011 of the bottom wall 201 on the other side.

[0067] In some embodiments, before the display screen assembly 100 and the middle frame 200 are assembled, a part of the first adhesive 300 is pre-prepared on one of the display screen assembly 100 and the middle frame 200, and another part of the first adhesive 300 is pre-prepared on the other of the display screen assembly 100 and the middle frame 200. When the display screen assembly 100 and the middle frame 200 are assembled, the part of the first adhesive 300 and the other part of the first adhesive 300 are bonded. For example, the part of the first adhesive 300 is pre-prepared on the display screen assembly 100, and the part of the first adhesive 300 can be pre-prepared on the first side surface 1012, can be pre-prepared on the second bottom surface 1021, or can be pre-prepared on the first side surface 1012 and the second bottom surface 1021. The other part of the first adhesive 300 is pre-prepared on the middle frame 200, and the other part of the first adhesive 300 can be pre-prepared on the first side wall 202, can be pre-prepared on the part 2011 of the bottom wall 201, or can be pre-prepared on the first side wall 202 and the part 2011 of the bottom wall 201.

[0068] The embodiments of the present application do not make specific limitations on the wall or surface on which the first adhesive 300 is pre-prepared, nor do they make specific limitations on whether the first adhesive 300 is pre-prepared on the wall or surface in whole or in part. The first adhesive 300 is pre-prepared between the first side surface 1012, the first side wall 202, the second bottom surface 1021, and the part 2011 of the bottom wall 201, and plays a role in bonding the display screen assembly 100 and the middle frame 200, which all belong to the scope limited by the embodiments of the present application.

[0069] In the connecting structure 1000 provided by the embodiment, the first side surface 1012 of the display module 101 and the first side wall 202 of the middle frame 200 are oppositely and spacedly arranged along the first direction, and the part 2011 of the bottom wall 201 of the middle frame 200 located between the first side surface 1012 and the first side wall 202 is oppositely and spacedly arranged with the second bottom surface 1021 of the panel 102 along the second direction, so that a space is formed between the first side surface 1012, the first side wall 202, the second bottom surface 1021 and the part 2011 of the bottom wall 201, and the first adhesive 300 is arranged in the space.

[0070] By containing the first adhesive 300 in the space, the first adhesive 300 bonds the middle frame 200 and the display module 100. By the first adhesive 300, the amount of the original adhesive between the middle frame 200 and the display module 100 can be reduced, so that the size of the space where the original adhesive is located can be reduced, and the width size of the black border of the connecting structure 1000 can be reduced in the first direction, so that the width size of the black border can be reduced.

[0071] The scheme can allow the size of the middle frame 200 in the first direction to be reduced as a whole. After the display module 100 and the middle frame 200 are assembled, the distance between the display module 100 and the middle frame 200 in the first direction can be reduced, including allowing the size of the first side surface 1012 and the first side wall 202 in the first direction to be reduced, for example, from 0.4 mm to 0.2 mm, which means that the original first side wall 202 of the middle frame 200 is recessed by 0.2 mm in the first direction towards the first side surface 1012. The display module 100 is provided with the first side surface 1012 on opposite sides in the first direction, and the middle frame 200 is provided with the first side wall 202 on opposite sides in the first direction. For the connecting structure 1000 as a whole, the opposite sides are recessed by 0.2 mm in the first direction, that is, the width of the black border on the opposite sides can be reduced by 0.2 mm respectively, and the total width of the black border can be reduced by 0.4 mm.

[0072] It should be noted that in the field of connecting structure 1000, due to the precision of the manufacturing equipment, if the connecting structure 1000 is not changed, it is difficult to reduce the width of the black border by 0.1 mm while ensuring good bonding strength. By the connecting structure 1000 provided by the embodiment, the width of the black border is reduced by 0.2 mm on one side, so that the width of the black border on the opposite sides can be reduced by 0.4 mm, thereby significantly improving the screen-to-body ratio of the connecting structure 1000. In addition, the first adhesive 300 is arranged in the space by being prefabricated before the display module 100 and the middle frame 200 are assembled, which solves the problem that the dispensing cannot reach the space and thus the space cannot be utilized.

[0073] For example,Figure 1 and Figure 3 As shown in FIG. 1, the width of the fixed black border formed by the four edges of the display module 101 is 0.7 mm. Figure 1 FIG. 2 is a sectional view of the existing connection structure along the second direction, and Figure 1 In FIG. 2, the distance between the first side wall of the middle frame 12' and the first side of the display module 111' along the first direction is 0.4 mm, the space where the distance is located is in an empty state, and the total width of the black border of the display surface is 1.5 mm.

[0074] Figure 3 FIG. 3 is a sectional view of the connection structure 1000 provided by the present embodiment along the second direction, and Figure 3 In FIG. 3, the distance between the first side wall 202 of the middle frame 200 and the first side 1012 of the display module 101 along the first direction is reduced to 0.2 mm, and the width of the black border on the opposite sides of the connection structure 1000 is reduced by 0.2 mm, and the total width of the black border is reduced by 0.4 mm, and the total width of the black border is 1.1 mm.

[0075] In the manufacturing process, the first adhesive 300 is prefabricated on the display screen assembly 100 or the middle frame 200, and then the display screen assembly 100 and the middle frame 200 are assembled, so that the distance between the first side wall 202 of the middle frame 200 and the first side 1012 of the display module 101 along the first direction is kept at 0.2 mm, and the first adhesive 300 is fitted or interference fitted in the distance along the first direction, and after the display screen assembly 100 and the middle frame 200 are assembled, they are bonded by the first adhesive 300. In some embodiments, the distance between the first side wall 202 of the middle frame 200 and the first side 1012 of the display module 101 along the first direction is 0.2 mm.

[0076] In some embodiments, the first adhesive 300 is prefabricated on the first side wall 202 and the part 2011 of the bottom wall 201 before the display screen assembly 100 and the middle frame 200 are assembled, and is bonded on the first side 1012 when the display screen assembly 100 and the middle frame 200 are assembled.

[0077] Before the display screen assembly 100 and the middle frame 200 are assembled, the first adhesive 300 is prefabricated on the first side wall 202 and the part 2011 of the bottom wall 201, which can improve the stability of the first adhesive 300 on the middle frame 200, and through the support of the part 2011 of the bottom wall 201 to the first adhesive 300, the stability of the first adhesive 300 between the first side 1012 and the first side wall 202 can be improved.

[0078] The first adhesive 300 can be bonded with the second bottom surface 1021, or can be spaced apart from the second bottom surface 1021. In some embodiments, as shown in FIG. 1, the first adhesive 300 is bonded with the second bottom surface 1021. Figure 4As shown, when the panel 102 is provided with the stepped surface 1022, the stepped surface 1022 and the stepped wall 203 are oppositely arranged along the second direction, so as to provide mutual positioning of the display screen assembly 100 and the middle frame 200 along the second direction. At this time, the first adhesive 300 can be arranged spaced apart from the second bottom surface 1021.

[0079] When the panel 102 is not provided with the stepped surface 1022, that is, the second side surface 1023 and the second bottom surface 1021 are directly connected, and the stepped wall 203 is located between the second side surface 1023 and the second side wall 204 along the first direction, at this time, the first adhesive 300 is connected to the second bottom surface 1021 and the part 2011 of the bottom wall 201 along the two sides of the second direction respectively, that is, the first adhesive 300 is bonded to the second bottom surface 1021, and the first adhesive 300 can provide mutual positioning of the display screen assembly 100 and the middle frame 200 along the second direction.

[0080] In some embodiments, the first adhesive 300 is pre-prepared on the first side surface 1012 before the display screen assembly 100 and the middle frame 200 are assembled, and is bonded to the part 2011 of the bottom wall 201 and the first side wall 202 when the display screen assembly 100 and the middle frame 200 are assembled.

[0081] Before the display screen assembly 100 and the middle frame 200 are assembled, the first adhesive 300 is pre-prepared on the first side surface 1012, and the first adhesive 300 is optionally pre-prepared on the second bottom surface 1021, or is arranged spaced apart from the second bottom surface 1021. The first adhesive 300 is bonded to the part 2011 of the bottom wall 201 and the first side wall 202, and the support of the first adhesive 300 by the part 2011 of the bottom wall 201 can improve the stability of the first adhesive 300 between the first side surface 1012 and the first side wall 202.

[0082] Referring to Figure 3 As shown, in some embodiments, the connecting structure 1000 further includes a second adhesive 400. The panel 102 has a stepped surface 1022 extending along the first direction and connected to the second bottom surface 1021, the stepped surface 1022 and the stepped wall 203 are oppositely and spaced apart along the second direction, and the second adhesive 400 is arranged between the stepped surface 1022 and the stepped wall 203 and bonds the stepped surface 1022 and the stepped wall 203.

[0083] When the second adhesive 400 is arranged separately and the third adhesive 500 is not arranged, the second adhesive 400 is arranged between the stepped surface 1022 and the stepped wall 203, the second adhesive 400 is an annular structure continuously extending along the circumference of the connecting structure 1000, and plays a role of connecting and sealing the stepped surface 1022 and the stepped wall 203, thereby playing a role of sealing the display screen assembly 100 and the middle frame 200, and playing a role of waterproofing and dustproofing from the circumference of the connecting structure 1000.

[0084] The stepped surface 1022 and the stepped wall 203 both extend along the first direction, and the second adhesive 400 located between the stepped surface 1022 and the stepped wall 203 also extends along the first direction. In the scheme in which the second adhesive 400 is arranged to be spaced between the first adhesive 300 and the second bottom surface 1021, the second adhesive 400 can extend into the space between the first adhesive 300 and the second bottom surface 1021 along a direction opposite to the first direction, so as to assist in positioning and bonding.

[0085] In some embodiments, the second adhesive 400 is pre-prepared on one of the stepped surface 1022 and the stepped wall 203 before the display screen assembly 100 and the middle frame 200 are assembled, and is bonded to the other of the stepped surface 1022 and the stepped wall 203 when the display screen assembly 100 and the middle frame 200 are assembled. In some specific embodiments, the second adhesive 400 is pre-prepared on the stepped wall 203 before the display screen assembly 100 and the middle frame 200 are assembled, and is bonded to the stepped surface 1022 when the display screen assembly 100 and the middle frame 200 are assembled.

[0086] In some embodiments, the second adhesive 400 is filled between the stepped wall 203 and the stepped surface 1022 after the display screen assembly 100 and the middle frame 200 are assembled. In this case, the second adhesive 400 is filled between the stepped wall 203 and the stepped surface 1022 after the display screen assembly 100 and the middle frame 200 are assembled, and the distance between the stepped wall 203 and the stepped surface 1022 along the second direction is determined.

[0087] Referring to Figure 3 In some embodiments, the connection structure 1000 further includes a third adhesive 500. The panel 102 has a second side surface 1023 extending along the second direction and connected to the stepped surface 1022, and the middle frame 200 has a second side wall 204 extending along the second direction and connected to the stepped wall 203. The second side surface 1023 and the second side wall 204 are arranged to be spaced apart along the first direction, and the third adhesive 500 is arranged between the second side surface 1023 and the second side wall 204 and bonds the second side surface 1023 and the second side wall 204.

[0088] The third adhesive 500 is arranged between the second side surface 1023 and the second side wall 204. The third adhesive 500 is in the form of an annular structure continuously extending along the circumference of the connection structure 1000, and functions to connect and seal the second side surface 1023 and the second side wall 204, and to prevent water and dust from entering from the circumference of the connection structure 1000.

[0089] The second side surface 1023 and the second side wall 204 both extend along the second direction, and the third adhesive material 500 located between the second side surface 1023 and the second side wall 204 also extends along the second direction. In combination with the arrangement of the second adhesive material 400, the third adhesive material 500 extending along the second direction can be integrally connected with the second adhesive material 400 extending along the first direction, or can be spaced apart.

When the second adhesive material 400 and the third adhesive material 500 are arranged in a pre-preparation manner, they can be pre-prepared on the same component, for example, both pre-prepared on the middle frame 200 or both pre-prepared on the panel 102. When the second adhesive material 400 and the third adhesive material 500 are arranged in a pre-preparation manner, they can be pre-prepared on different components, for example, the second adhesive material 400 is pre-prepared on one of the middle frame 200 and the panel 102, and the third adhesive material 500 is pre-prepared on the other of the middle frame 200 and the panel 102. In some embodiments, the second adhesive material 400 and the third adhesive material are both arranged in a filling manner.

[0094] In some embodiments, the third adhesive material 500 is an annular structure continuously extending along the circumference of the connecting structure 1000, and functions to connect and seal the second side surface 1023 and the second side wall 204. In this case, the second adhesive material 400 can be omitted.

[0095] Referring to Figure 7As shown, in some embodiments, the connecting structure 1000 further comprises a fourth adhesive 600. The panel 102 has a second side surface 1023 extending along the second direction and connected to the second bottom surface 1021, the middle frame 200 has a second side wall 204 extending along the second direction and connected to the step wall 203, the step surface 1022 is cancelled, the second side surface 1023 and the second side wall 204 are arranged in the first direction, the step wall 203 is arranged between the second side surface 1023 and the second side wall 204, and the fourth adhesive 600 is arranged between and bonded to the second side surface 1023, the second side wall 204 and the step wall 203.

[0096] In some embodiments, the first adhesive 300 is arranged in the second direction and spaced apart from the second bottom surface. In some embodiments, the first adhesive 300 is arranged on both sides of the second bottom surface 1021 and the portion 2011 in the second direction, that is, the first adhesive 300 is bonded to the second bottom surface 1021, and the first adhesive 300 can provide mutual positioning of the display assembly 100 and the middle frame 200 in the second direction.

[0097] The second side surface 1023 and the second side wall 204 both extend along the second direction, and the fourth adhesive 600 arranged therebetween also extends along the second direction. The fourth adhesive 600 extending along the second direction can be integrally connected with the first adhesive 300, or can be spaced apart.

[0098] In some embodiments, the fourth adhesive 600 is pre-prepared on the second side wall 204 and the step wall 203 before the display assembly 100 and the middle frame 200 are assembled, and is bonded to the second side surface 1023 when the display assembly 100 and the middle frame 200 are assembled. Alternatively, the fourth adhesive 600 is pre-prepared on the second side surface 1023 before the display assembly 100 and the middle frame 200 are assembled, and is bonded to the second side wall 204 or the step wall 203 when the display assembly 100 and the middle frame 200 are assembled.

[0099] In some embodiments, the fourth adhesive 600 is filled between the second side surface 1023, the second side wall 204 and the step wall 203 after the display assembly 100 and the middle frame 200 are assembled.

[0100] In some embodiments, the first adhesive 300 is an annular structure continuously extending along the circumference of the connecting structure 1000, or the first adhesive 300 comprises a plurality of adhesive units arranged in the circumference of the connecting structure 1000.
