[0044] In the related art, the display module presents a multi-layer structure. The preparation process of the display module includes a glue injection process at the edges of the multi-layer structure. However, due to the step structure formed by the multi-layer structure on the non-display side of the display module, in order to avoid the glue flowing along the gap formed by the step structure to overflow to the display area during the glue injection around the edges, a dam glue is usually applied at the gap before the glue injection. During the subsequent glue injection, the dam glue forms an interference fit with the silicone inner film of the glue injection mold, the silicone inner film presses the dam glue to form a blocking structure, preventing the glue injected around the edges from overflowing along the gap to the display area.

[0045] The above method can solve the overflow problem at the step to some extent, but due to the large height tolerance of the step structure, the dam glue is made by dispensing process, and there is a certain tolerance between the glue height and the glue width, so that there is fluctuation when the dam glue cooperates with the inclined surface of the silicon inner mold. If the interference is insufficient, there is still a certain proportion of overflow risk, and if the interference is too much, it is easy to cause appearance defects of the imprint, which will affect the production yield.

[0046] Therefore, the embodiments of the present application provide an insulating adhesive tape, a cushion block, a display module and a method for assembling the same, and a display device. A blocking part is arranged in the inherent film layer of the display module (including the insulating adhesive tape and / or the cushion block), and the blocking part is used instead of the dam glue. Since the blocking part is part of the inherent film layer of the display module and belongs to the structure of the module, the blocking part is assembled together through the module process, so that the position accuracy and structure parameter accuracy of the blocking part can be controlled. At the same time, the material selection range of the blocking part is wider, the deformation amount is better, and the filling effect is better, so that no pressure marks or damage are caused to the screen body. In addition, the process of dispensing the dam glue is cancelled, the preparation period is shortened, and the cost is reduced. In summary, the above three reasons improve the yield of the display module.

[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0048] In the drawings, the sizes of the layers and regions can be exaggerated for clarity. It can be understood that when a structure is referred to as being "on" or "under" another structure, it can be directly on or under the other structure, or there can be an intermediate structure. The same reference signs always indicate the same structure. The structures mentioned herein include any of the film layers, elements, devices, members, and assemblies.

[0049] When a structure is referred to as being "connected" to another structure, it can be directly connected to the other structure, or indirectly connected to the other structure in a manner that one or more intermediate structures are placed between them.

[0050] The first aspect of the present application provides an insulating adhesive tape. Figure 1 The top view of the insulating adhesive tape provided by an embodiment of the present application. Figure 2 For Figure 1 The cross-sectional structure schematic diagram of the insulating adhesive tape along the N1N2 line is shown. The above Figure 1 And Figure 2As shown, the insulating tape 40 comprises a first main body part 43, a first blocking part 41 and a second blocking part 42. The first blocking part 41 and the second blocking part 42 are respectively located at opposite sides of the first main body part 43 and connected with the first main body part 43.

[0051] In an embodiment, the first blocking part 41 and the second blocking part 42 are symmetrically arranged.

[0052] For example, the first main body part 43 comprises a second side L2, a first side L1 and a third side L3 connected in sequence. The first blocking part 41 is in contact with the second side L2 and close to the intersection of the second side L2 and the first side L1, and the second blocking part 42 is in contact with the third side L3 and close to the intersection of the third side L3 and the first side L1.

[0053] In an embodiment, the first main body part 43 further comprises a fourth side L4, which is arranged opposite to the first side L1.

[0054] In an embodiment, the shape of at least one of the first main body part 43, the first blocking part 41 and the second blocking part 42 comprises a rectangle.

[0055] In an embodiment, the distance D1 between the edge close to the first side L1 and the first side L1 of the first blocking part 41 and the second blocking part 42 is greater than or equal to 0.4 mm and less than or equal to 1 mm. For example, the distance D1 can be 0.4 mm, 0.6 mm, 0.8 mm, 1 mm, etc. The advantage is that when the insulating tape 40 is applied to the display module later, the first blocking part 41 and the second blocking part 42 are prevented from interfering with the sealant around, affecting the blocking effect.

[0056] In an embodiment, in the extension direction of the second side L2 and the third side L3, the length D2 of the first blocking part 41 and the second blocking part 42 is greater than or equal to 0.4 mm and less than or equal to 1 mm. For example, the length D2 can be 0.4 mm, 0.6 mm, 0.8 mm, 1 mm, etc. The advantage is that when the insulating tape 40 is applied to the display module later, the first blocking part 41 and the second blocking part 42 are prevented from pressing the pads of the binding part, while being firm enough to have a good blocking effect.

[0057] In an embodiment, in the extension direction of the first side L1, the width D3 of the first blocking part 41 and the second blocking part 42 is greater than or equal to 0.5 mm and less than or equal to 1 mm. For example, the width D3 can be 0.5 mm, 0.7 mm, 0.9 mm, 1 mm, etc. The advantage is that when the insulating tape 40 is applied to the display module later, it is ensured that the first blocking part 41 and the second blocking part 42 can be interference fit with the silicone inner film of the injection mold.

[0058] In one embodiment, the thickness D4 of the first blocking part 41 and the second blocking part 42 in the direction perpendicular to the first side L1 and the second side L2 is greater than or equal to 0.2mm and less than or equal to 0.5mm. Exemplarily, the thickness D4 can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc. The advantage is that when the insulating tape 40 is applied to the display module later, it ensures that the first blocking part 41 and the second blocking part 42 can be in interference fit with the silicone inner film of the glue injection mold.

[0059] In one embodiment, the thickness of the first main part 43, the first blocking part 41 and the second blocking part 42 is equal. The advantage is that it is convenient for process implementation.

[0060] In one embodiment, the material of the first main part 43 is different from that of the first blocking part 41 and the second blocking part 42. Exemplarily, the compression ratio of the material of the first blocking part 41 and the second blocking part 42 is greater than 40%, and the compression modulus is less than 50mpa. For example, the material of the first blocking part 41 and the second blocking part 42 includes any one of polyurethane and foam. Such material can further improve the sealing reliability and avoid extrusion marks.

[0062] In one embodiment, the third blocking part 311 and the fourth blocking part 312 are symmetrically arranged.

Exemplarily, the distance D5 can be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc. The advantage is that when the insulating tape 40 is applied to the display module subsequently, the third blocking part 311 and the fourth blocking part 312 are prevented from interfering with the sealant around, affecting the blocking effect.

[0066] In one embodiment, the length D6 of the third blocking part 311 and the fourth blocking part 312 in the extension direction of the sixth edge L6 and the seventh edge L7 is greater than or equal to 0.35 mm and less than or equal to 1 mm.

[0067] In one embodiment, the width D7 of the third blocking part 311 and the fourth blocking part 312 in the extension direction of the fifth edge L5 is greater than or equal to 0.8 mm and less than or equal to 1.5 mm.

[0070] In one embodiment, the interface between the first support sub-portion 3111 and the second main body portion 313 is spaced apart from the edge of the second main body portion 313 close to the second support sub-portion 3121, and a first interval D9 is provided therebetween.

The first interval D9 and the second interval D10 are provided to reserve space allowance when the bending portion 22 is bent, so as to avoid the first elastic sub-portion 3112 and the second elastic sub-portion 3122 from damaging the solder pads in the binding portion 23.

[0071] In one embodiment, the first interval D9 and the second interval D10 are greater than or equal to 0.3 mm and less than or equal to 0.5 mm. Exemplarily, the first interval D9 and the second interval D10 can be any one of 0.3 mm, 0.4 mm, 0.5 mm.

The advantage is that it is easy to implement the process.

[0074] In one embodiment, the first support sub-portion 3111 and the first elastic sub-portion 3112 are flush with the edge close to the fifth edge L5, and flush with the edge close to the eighth edge L8. The second support sub-portion 3121 and the second elastic sub-portion 3122 are flush with the edge close to the fifth edge L5, and flush with the edge close to the eighth edge L8.

Exemplarily, the material of the first elastic sub-portion 3112 and the second elastic sub-portion 3122 has a compression ratio greater than 40% and a compression modulus less than 50 mpa. For example, the material of the first elastic sub-portion 3112 and the second elastic sub-portion 3122 includes any one of polyurethane and foam.

[0077] The third aspect of the present application provides an assembling method of a display module. Figure 5 The flow chart of the assembling method of the display module is provided for an embodiment of the present application. As shown in the figure, Figure 5 The assembling method 500 of the display module comprises the following steps:

[0078] In step S510, the display panel, the cushion block and the composite tape are aligned and attached. The display panel comprises a display part, a bending part and a binding part connected in sequence. The composite tape is located on the non-display side of the display part, and the cushion block is located on the side of the composite tape away from the display part.

[0079] In step S520, the bending part is bent towards the non-display side, and the binding part is attached to the cushion block.

[0080] In step S530, the insulating tape is attached to the side of the binding part away from the display part, and the intermediate product of the display module is obtained.

[0081] In step S540, the intermediate product of the display module is placed in the glue injection mold for glue injection, and the display module is obtained.

[0082] In one embodiment, the insulating tape 40 shown in Figure 1 and Figure 2 is used in step S510.

[0083] Figures 6a-6c The structure diagram of the intermediate product obtained by the assembling method shown in Figure 5 is provided for the first embodiment of the present application.

[0084] Firstly, referring to Figure 6a and Figure 6b , in the alignment and attachment process of step S510, the first blocking part 41 and the second blocking part 42 are both directed towards the binding part 23. On the side close to the binding part 23, the distance S1 between the edge of the first blocking part 41 and the second blocking part 42 and the edge of the composite tape 321 is greater than or equal to 0.3mm and less than or equal to 0.5mm.

[0085] It should be noted that the alignment and attachment process can also include the cover plate 10, the polarizer 33, the adhesive layer 34, the support layer 322, etc. The cover plate 10, the adhesive layer 34, the polarizer 33, the display part 21, the support layer 322, the composite tape 321, the cushion block 310, the binding part 23 and the insulating tape 40 are sequentially stacked.

[0086] Next, referring to Figure 6cIn the glue injection process of step S540, the silicone inner film 70 of the glue injection mold extrudes the first and second blocking parts 41 and 42, causing the first and second blocking parts 41 and 42 to deform. The silicone inner film 70 is in interference fit with the first and second blocking parts 41 and 42. In this way, overflow of glue to the display area can be prevented.

[0087] In another embodiment, the insulating adhesive tape 40 shown in Figure 3 and Figure 4 is used in step S510.

[0088] Figures 7a-7c The assembling method shown in Figure 5 provides an intermediate product structure diagram.

[0089] First, referring to Figure 7a and Figure 7b , in the alignment and bonding process of step S510, the third and fourth blocking parts 311 and 312 are both directed towards the binding part 23. On the side close to the binding part 23, the distance S2 between the edges of the third and fourth blocking parts 311 and 312 and the edges of the composite adhesive tape 321 is greater than or equal to 0.15 mm and less than or equal to 0.5 mm.

[0090] Next, referring to Figure 7c , in the glue injection process of step S540, the silicone inner film 70 of the glue injection mold extrudes the third and fourth blocking parts 311 and 312, causing the third and fourth blocking parts 311 and 312 to deform. The silicone inner film 70 is in interference fit with the third and fourth blocking parts 311 and 312. In this way, overflow of glue to the display area can be prevented.

[0091] In yet another embodiment, the insulating adhesive tape 40 shown in Figure 1 and Figure 2 is used in step S510, and the cushioning block 310 shown in Figure 3 and Figure 4 is used.

[0092] Figures 8a-8c The assembling method shown in Figure 5 provides an intermediate product structure diagram.

[0093] First, referring to Figure 8a and Figure 8bDuring the alignment and lamination process in step S510, the first and second blocking portions 41, 42, third and fourth blocking portions 311, 312 all face the binding portion 23. On the side close to the binding portion 23, the distance S1 between the edges of the first and second blocking portions 41, 42 and the edge of the composite tape 321 is greater than or equal to 0.3 mm and less than or equal to 0.5 mm, and the distance S2 between the edges of the third and fourth blocking portions 311, 312 and the edge of the composite tape 321 is greater than or equal to 0.15 mm and less than or equal to 0.5 mm.

[0094] Next, see Figure 8c During the glue injection process in step S540, the silicone inner film 70 of the glue injection mold squeezes the first barrier 41, the second barrier 42, the third barrier 311, and the fourth barrier 312, causing them to deform. The silicone inner film 70 forms an interference fit with the first barrier 41, the second barrier 42, the third barrier 311, and the fourth barrier 312. This prevents glue from overflowing into the display area.

[0095] It should be noted that, see Figure 8a and Figure 8b In this embodiment, the length D2 of the first blocking portion 41 and the second blocking portion 42 is greater than or equal to 0.2 mm and less than or equal to 0.5 mm, the width D3 is greater than or equal to 0.5 mm and less than or equal to 0.8 mm, and the thickness D4 is greater than or equal to 0.15 mm and less than or equal to 0.35 mm. The length D11 of the first elastic sub-portion 3112 and the second elastic sub-portion 3122 is greater than or equal to 0.35 mm and less than or equal to 1 mm, the width D12 is greater than or equal to 0.5 mm and less than or equal to 1 mm, and the thickness D13 is greater than or equal to 0.05 mm and less than or equal to 0.15 mm.

[0096] A fourth aspect of the present application provides a display module. Figure 9 This is a schematic top view of the structure of the display module provided in the first embodiment of the present application. Figure 10 for Figure 9 The diagram shows a cross-sectional structure of the display module along line A1A2. Figure 11 for Figure 9 The diagram shows the cross-sectional structure of the display module along line A3A4. Figure 12 for Figure 9 The cross-sectional structure diagram of the display module along the A5A6 line is shown. Figures 9-12As shown, the display module has a display area AA and a frame area NA surrounding the display area AA. The display module comprises a cover plate 10, a display panel 20, an insulating tape 40, at least one second functional layer 32, a spacer 310, a sealing glue 50, a first barrier structure and a second barrier structure. The display panel 20 comprises a display part 21, a bending part 22 and a binding part 23 connected in sequence. The bending part 22 is in a bending state. The binding part 23 is located on the side of the display part 21 away from the cover plate 10. The binding part 23 extends along a first direction x directed from the frame area NA to the display area AA. The at least one second functional layer 32 is located between the display part 21 and the binding part 23. At least part of the insulating tape 40 is located on the side of the binding part 23 away from the display part 21. The spacer 310 is located between the binding part 23 and the second functional layer 32. The sealing glue 50 is located on the side of the cover plate 10 and covers the bending part 22, the second functional layer 32 and the four peripheral edges of the display part 21. The first barrier structure covers part of the sidewall of the binding part 23 and the spacer 310 on the first side in a second direction y, and the second barrier structure covers part of the sidewall of the binding part 23 and the spacer 310 on the second side in the second direction y, the second direction y being perpendicular to the first direction x. The first barrier structure and the second barrier structure are both located on the side of the sealing glue 50 close to the display area AA and abut the sealing glue 50; the first barrier structure is connected to the insulating tape 40 and / or the spacer 310, and the second barrier structure is connected to the insulating tape 40 and / or the spacer 310.

[0097] In the present embodiment, the first barrier structure comprises a first barrier part 41, and the second barrier structure comprises a second barrier part 42, the first barrier part 41 and the second barrier part 42 being connected to the insulating tape 40 respectively. In the second direction y perpendicular to the first direction x, the first barrier part 41 and the second barrier part 42 are respectively bent from the side of the binding part 23 away from the cover plate 10 towards the second functional layer 32, cover the sidewall of the binding part 23 and the first functional layer 31, and contact the surface of the second functional layer 32 away from the cover plate 10 closest to the first functional layer 31. The sealing glue 50 is located on the side of the cover plate 10 and covers the bending part 22, the second functional layer 32 and the four peripheral edges of the display part 21.

[0098] The cover plate 10 can be an ultra-thin glass cover plate, a plastic cover plate, etc. In an embodiment, the cover plate 10 can be a flexible cover plate.

[0099] The display panel 20 has a display function. For example, the display panel 20 comprises an organic light-emitting diode (Organic Light-Emitting Diode) display panel. The display panel 20 comprises the display part 21, the bending part 22 and the binding part 23. The display part 21 is used to realize the display function. The binding part 23 is provided with a pad for binding connection with the circuit board 60. The binding part 23 can also be provided with a driving chip.

[0100] The insulating tape 40 covers the driving chip on the side of the binding portion 23 away from the display portion 21, and some electronic components on the circuit board, and plays a role of fixing, insulation and protection.

[0101] The functional layer is used to provide auxiliary functions other than display. The functional layer provided in this embodiment includes a first functional layer 31 and a second functional layer 32. The first functional layer 31 is located on the side of the second functional layer 32 close to the binding portion 23. The first functional layer 31 includes a cushioning block, for example. The second functional layer 32 includes a composite tape 321 and a support layer 322, and the composite tape 321 is located on the side of the support layer 322 close to the first functional layer 31. The composite tape 321 contacts the cushioning block 310, for example. The composite tape 321 includes a copper foil, for example. The functional layer can also include a polarizer 33 and a glue layer 34 between the display portion 21 and the cover plate 10.

[0102] The first functional layer 31 has an area equivalent to that of the display portion 21, and the second functional layer 32 has an area equivalent to that of the binding portion 23. The side wall of the first functional layer 31 and the binding portion 23 forms a stepped structure on the side of the second functional layer 32 away from the cover plate 10. In the first direction x, the stepped structure encloses a first slit and a second slit from the frame area NA to the display area AA, and the first blocking portion 41 and the second blocking portion 42 block the first slit and the second slit, respectively. In this way, when the display module is placed in a glue injection mold for four-side glue injection to form the sealing glue 50, the silicone inner film of the glue injection mold is in interference fit with the first blocking portion 41 and the second blocking portion 42, and the glue will not overflow from the first slit and the second slit to the display area AA. At the same time, since the first blocking portion 41 and the second blocking portion 42 are part of the insulating tape 40 and belong to the structure of the module, they are assembled together through the module process, so the position accuracy and structure parameter accuracy of the first blocking portion 41 and the second blocking portion 42 can be controlled, thereby improving the yield of the display module.

[0103] In one embodiment, the insulating tape 40 includes a first blocking portion 41 and a second blocking portion 42, and the first blocking portion 41 and the second blocking portion 42 are located on the side of the binding portion 23 away from the display portion 21. Figures 9-12 As shown, the insulating tape 40 also includes a first main portion 43, which is located between and connected to the first blocking portion 41 and the second blocking portion 42. The first blocking portion 41 and the second blocking portion 42 are symmetrically arranged, for example. The material of the first main portion 43 is different from that of the first blocking portion 41 and the second blocking portion 42, for example. The material of the first blocking portion 41 and the second blocking portion 42 has a greater elasticity than that of the first main portion 43, so as to have a larger deformation amount and better fill the first slit and the second slit. The surface of the first blocking portion 41 and the second blocking portion 42 away from the side wall of the binding portion 23 is a slope surface, for example.

[0104] Figure 13 In order to Figure 9A partial enlarged view of the display panel is shown. In combination with Figure 9 and Figure 13 As shown, the first main body part 43 includes a first side L1, which is located in the frame area NA. Exemplarily, in the frame area NA, the orthographic projection of the first side L1 on the cover plate 10 is located between the edge of the orthographic projection of the display part 21 on the cover plate 10 and the edge of the orthographic projection of the second functional layer 32 closest to the binding part 23 on the cover plate 10. Exemplarily, the first side L1 extends along the second direction y.

[0105] In one embodiment, the first main body part 43 further includes a second side L2 and a third side L3 oppositely arranged, and the second side L2, the first side L1 and the third side L3 are sequentially connected. The first blocking part 41 contacts the second side L2 and is close to the intersection of the second side L2 and the first side L1, and the second blocking part 42 contacts the third side L3 and is close to the intersection of the third side L3 and the first side L1. Exemplarily, the second side L2 and the third side L3 extend along the first direction x.

[0106] In one embodiment, the orthographic projection of the second side L2 and the third side L3 on the cover plate 10 is located between two opposite sides of the orthographic projection of the binding part 23 on the cover plate 10.

[0107] In one embodiment, the first main body part 43 further includes a fourth side L4, which is oppositely arranged with the first side L1.

[0108] In one embodiment, the orthographic projection shape of the first main body part 43 on the cover plate 10 includes a rectangle.

[0109] In one embodiment, the display module further includes a flexible circuit board 60, which is bound and connected with the binding part 23, and the first main body part 43 covers part of the binding part 23 and part of the flexible circuit board 60.

[0110] In one embodiment, the material of the first blocking part 41 and the second blocking part 42 has a compression ratio greater than 40% and a compression modulus less than 50mpa. Exemplarily, the material of the first blocking part 41 and the second blocking part 42 includes any one of polyurethane and foam.

[0111] Figure 14 A partial top view structural schematic diagram of a display module provided for the second embodiment of the present application is shown. Figure 15 For Figure 14 A cross-sectional structural schematic diagram of the display module along the A7A8 line is shown. The display module provided in the present embodiment and Figures 9-13 The difference between the display module shown and the display module shown in the first embodiment is that, in the present embodiment, the blocking part is arranged on the pad block instead of being arranged on the insulating tape 40. It should be noted that, in order to facilitate the display of the edge of the pad block 310, Figure 14The insulating tape 40 is not shown. In comparison, the blocking portion is arranged on the cushion block 310, which has the advantage that the insulating tape 40 is attached after the display panel is bent, so that the alignment accuracy of the blocking portion is easier to control when the alignment is attached, thereby reducing the difficulty of attachment.

[0112] Specifically, as shown in Figure 14 and Figure 15 , in the present embodiment, the first blocking structure includes a third blocking portion 311, and the second blocking structure includes a fourth blocking portion 312. The third blocking portion 311 and the fourth blocking portion 312 are respectively connected to the cushion block 310. In a second direction y perpendicular to the first direction x, the third blocking portion 311 and the fourth blocking portion 312 are respectively bent by the binding portion 23 toward the binding portion 23 on the side of the cover plate 10, cover the side wall of the binding portion 23, and contact the insulating tape 40.

[0113] The same technical details of the display module shown in the present embodiment and Figures 9-13 are not described again. The difference between the two embodiments is that, in the present embodiment, the third blocking portion 311 and the fourth blocking portion 312 are respectively used instead of the first blocking portion 41 and the second blocking portion 42 to block the first slit and the second slit, and the same technical effects as in the first embodiment can be achieved.

[0114] In one embodiment, as shown in Figure 14 and Figure 15 , the cushion block 310 further includes a second main body portion 313, which is located between the third blocking portion 311 and the fourth blocking portion 312 and connects the third blocking portion 311 and the fourth blocking portion 312. For example, the third blocking portion 311 and the fourth blocking portion 312 are symmetrically arranged.

[0115] In one embodiment, as shown in Figure 14 and Figure 15 , the surfaces of the third blocking portion 311 and the fourth blocking portion 312 away from the side wall of the binding portion 23 are inclined surfaces.

[0116] In one embodiment, as shown in Figure 15 , the third blocking portion 311 includes a first supporting sub-portion 3111 and a first elastic sub-portion 3112 stacked together. The fourth blocking portion 312 includes a second supporting sub-portion 3121 and a second elastic sub-portion 3122 stacked together. The first supporting sub-portion 3111 and the second supporting sub-portion 3121 are connected to the second main body portion 313. The first elastic sub-portion 3112 is located on the side of the first supporting sub-portion 3111 closer to the binding portion 23. The second elastic sub-portion 3122 is located on the side of the second supporting sub-portion 3121 closer to the binding portion 23.

[0117] In an embodiment, the second body part 313 is made of the same material as the first support sub-part 3111 and the second support sub-part 3121. For example, the second body part 313 is integrally formed with the first support sub-part 3111 and the second support sub-part 3121.

[0118] In an embodiment, the second body part 313 is made of different material from the first elastic sub-part 3112 and the second elastic sub-part 3122. For example, the material of the first elastic sub-part 3112 and the second elastic sub-part 3122 has a compression ratio greater than 40% and a compression modulus less than 50mpa. For example, the material of the first elastic sub-part 3112 and the second elastic sub-part 3122 includes any one of polyurethane and foam.

[0119] In an embodiment, the first support sub-part 3111 and the second support sub-part 3121 are in contact with the surface of the cover plate 10 away from the second functional layer 32 closest to the binding part 23.

[0120] In an embodiment, the second body part 313 includes a fifth edge L5, and the fifth edge L5 is located in the frame area NA. For example, the fifth edge L5 extends along the second direction y.

[0121] In an embodiment, the second body part 313 further includes a sixth edge L6 and a seventh edge L7 opposite to each other, and the sixth edge L6, the fifth edge L5 and the seventh edge L7 are sequentially connected. The first support sub-part 3111 is in contact with the sixth edge L6 and close to the intersection of the sixth edge L6 and the fifth edge L5, and the second support sub-part 3121 is in contact with the seventh edge L7 and close to the intersection of the seventh edge L7 and the fifth edge L5.

[0122] In an embodiment, the second body part 313 further includes an eighth edge L8 opposite to the fifth edge L5.

[0123] For example, the orthogonal projection shape of any one of the second body part 313, the first support sub-part 3111 and the second support sub-part 3121 on the cover plate 10 includes a rectangle.

[0124] In an embodiment, at least one second functional layer 32 includes a composite tape 321 and a support layer 322, and the composite tape 321 is located on the side of the support layer 322 away from the cover plate 10. For example, the display module further includes a polarizer 33 and a glue layer 34 between the display part AA and the cover plate 10, and the polarizer 33 is located on the side of the glue layer 34 away from the cover plate 10.

The at least one second functional layer 32 is located on the first surface 10a of the cover plate 10. Figure 16The display module shown in the embodiment and the display module provided in any of the above embodiments differ in that, in the embodiment, the insulating tape 40 and the spacer 310 are both provided with blocking portions.

[0126] Specifically, as shown in Figure 9 、 Figure 14 and Figure 16 , the first blocking structure includes the first blocking portion 41 and the third blocking portion 311, and the second blocking structure includes the second blocking portion 42 and the fourth blocking portion 312. The first blocking portion 41 and the second blocking portion 42 are connected to the insulating tape 40 respectively, and the third blocking portion 311 and the fourth blocking portion 312 are connected to the spacer 310 respectively. In a second direction y perpendicular to the first direction x, the first blocking portion 41 and the second blocking portion 42 are respectively bent away from the side of the cover plate 10 toward the second functional layer 32 by the binding portion 23, and the third blocking portion 311 and the fourth blocking portion 312 are respectively bent toward the binding portion 23 by the side of the binding portion 23 close to the cover plate 10. The first blocking portion 41 and the third blocking portion 311 contact and cover the side walls of the binding portion 23 and the spacer 310, and the second blocking portion 42 and the fourth blocking portion 312 contact and cover the side walls of the binding portion 23 and the spacer 310.
