[0025] The following will be combined with the drawings in the embodiments of this specification to clearly and completely describe the technical solutions in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0026] In the description of the present disclosure, it should be noted that the terms "center", "upper", "lower", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the inventive product is usually placed when in use, which are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present disclosure. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0027] In the related art, in order to increase the screen-to-body ratio of electronic devices, a hole design is usually made in the display area. Figure 1FIG. 1 is a schematic diagram showing the structure of the hole area of ​​the display module in the related art. Figure 1 As shown, in order to realize the hole design of the display area, through holes H are usually opened in multiple film layers of the display module. As described in the background technology, in the process of hollowing out the screen body 11 in the display module to form the through hole H, the edge of the hollowed position of the screen body 11 is exposed, so that the exposed screen body edge is easily damaged by external force and causes cracks and other abnormalities.

[0028] In addition, during use of the display module, static electricity will exist inside the through hole H. The static electricity will enter the interior of the screen body 11 from the edge of the screen body 11 exposed to the through hole H, affecting the display effect and even causing static electricity damage to the screen body, thus affecting the service life of the display module.

[0029] In view of this, the present disclosure provides a display module, comprising: a cover plate; a screen body, located on one side of the cover plate, the screen body comprising a first through hole; a composite tape, located on a side of the screen body away from the cover plate, the composite tape comprising a metal layer, the metal layer comprising a first opening, the orthographic projection of the first opening on the cover plate is located within the orthographic projection range of the first through hole on the cover plate; and a protective block, located in the first through hole, covering the side wall of the first through hole, and contacting the metal layer.

[0030] Through the above design, the metal layer included in the composite tape can completely wrap and protect the hole area, and prevent external static electricity from entering the hole area; the protection block covers the exposed edge of the screen body to play a protective role, and the protection block can provide support for the softer metal layer to prevent its deformation. In this way, the external force damage and static electricity damage caused by the exposed edge of the screen body in the hole area can be solved, and the reliability and display effect of the display module can be improved.

[0031] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] Figure 2 FIG. 1 is a top view of a display module provided by an embodiment of the present disclosure. Figure 2 As shown, the display module includes a display area AA and a non-display area surrounding the display area AA. A hole area H is designed in the display area AA. Through holes are formed through the multiple film layers below the hole area H to realize the design of setting devices such as cameras and sensors in the hole area H.

[0033] Figure 3 Shown Figure 2 The structure diagram of the partial film layer of the display module in area B is shown in FIG. Figure 3 As shown, the display module includes a cover plate 310 , a screen body 320 , a composite tape 330 and a protection block 340 .

[0034] The screen body 320 is located on one side of the cover plate 310, and the screen body 320 includes a first through hole 321. The orthographic projection of the first through hole 321 on the screen body 320 covers the orthographic projection of the hole area on the screen body 320. That is, in order to achieve the same size of the hole area as in the related art, the opening area of ​​the first through hole 321 of the screen body 320 in this embodiment is relatively increased.

[0035] A composite tape 330 is disposed on the side of the screen body 320 away from the cover plate 310. The composite tape 330 includes a metal layer 331, and the metal layer 331 includes a first opening 3311. The orthographic projection of the first opening 3311 on the cover plate 310 is located within the orthographic projection range of the first through hole 321 on the cover plate 310. Exemplarily, the material of the metal layer includes a metal with high electrical conductivity, such as copper, aluminum, etc.

[0036] In the related art, continue to refer to Figure 1 , the composite tape 12 at the hole area cannot completely cover the film structure below. In this embodiment, the metal layer 331 shrinks inwardly toward the hole area so that it can completely wrap the screen body 320 below to protect the edge of the screen body 320. Since the metal layer 331 is conductive, the metal layer 331 can prevent static electricity outside the hole area from entering the hole area, thereby preventing external static electricity from entering the screen body 320 along the edge of the first through hole 321 and causing static damage to the screen body 320.

[0037] The protection block 340 is located in the first through hole 321 of the screen body 320. The protection block 340 covers the side wall of the first through hole 321. In this way, the protection block 340 can provide protection for the edge of the screen body 320 at the hole area to prevent it from being damaged by external forces; at the same time, it can also protect the screen body 320 from being affected by the external environment. It can be understood that the outer side wall of the protection block 340 may or may not contact the side wall of the first through hole 321; the protection block 340 only needs to cover the edge of the screen body 320 exposed in the hole area to achieve the protection of the edge of the screen body 320.

[0038] Since the metal layer 331 is relatively soft, it is easily deformed by external forces, causing compression to the screen body 320 below. Therefore, one side of the protection block 340 can be in contact with the metal layer 331, so that the protection block 340 can provide support for the metal layer 331. Exemplarily, the protection block 340 can be bonded to the metal layer 331, and while protecting the screen body 320 and the metal layer 331, the protection block 340 can also be fixed to improve the reliability of the display module.

[0039] The display module in this embodiment provides protection for the screen by shrinking the metal layer in the composite tape into the hole area so that it completely wraps the edge of the screen at the hole area. At the same time, static electricity outside the hole area is prevented from entering the hole area and entering the screen from the edge of the screen, thereby improving the display effect of the display module and preventing static electricity from damaging the screen. The protection block can support the metal layer to prevent it from being deformed by external forces. At the same time, the protection block covers the edge of the screen, protecting the screen from external damage and the influence of the external environment, thereby improving the reliability of the display module.

[0040] The specific structure of the protection block will be further described below in conjunction with the accompanying drawings.

[0041] In some embodiments, continue to refer to Figure 3 The protection block 340 includes a first surface 341 and a second surface 342 that are arranged opposite to each other. The first surface 341 faces the metal layer 331, and the second surface 342 faces the cover plate 310. The first surface 341 of the protection block 340 is bonded to a surface of the metal layer 331 that faces the first through hole 321, and the second surface 342 of the protection block 340 is bonded to a surface of the cover plate 310 that faces the first through hole 321, so as to fix the protection block 340 between the cover plate 310 and the metal layer 331 to prevent it from being displaced due to external force.

[0042] Exemplarily, the protection block 340 may be bonded to the metal layer 331 and / or the cover plate 310 by means of adhesive material, or the protection block 340 may be directly prepared by using a curing adhesive material.

[0043] The orthographic projection of the protection block 340 on the cover plate 310 is located between the first opening 3311 and the orthographic projection of the first through hole 321 on the cover plate 310; the distance between the first surface 341 and the second surface 342 of the protection block 340 is equal to the distance between the surfaces of the metal layer 331 and the cover plate 310 facing the first through hole 321, and the protection block 340 is respectively against the cover plate 310 and the metal layer 331, so that the protection block 340 can support the metal layer 331 to prevent the metal layer 331 from being too soft and deforming, thereby improving the reliability of the display module.

[0044] Figure 4 Shown Figure 2 The display module shown is a partial enlarged schematic diagram of area B. Figure 4As shown, the orthographic projection of the protection block on the cover plate includes a first edge 343 (indicated by a dotted line) and a second edge 344 (indicated by a solid line), and the second edge 344 is located inside the first edge 343. The second edge 344 coincides with the orthographic projection of the first opening of the metal layer on the cover plate; more specifically, the inner edge of the orthographic projection of the first surface of the protection block on the cover plate coincides with the orthographic projection of the first opening of the metal layer on the cover plate. In this way, it is possible to ensure that the protection block supports the edge of the metal layer at the hole area position, and prevent the first opening of the metal layer from being deformed by external force, affecting the opening shape of the hole area and the normal operation of the device in the hole area.

[0045] In some embodiments, the first edge of the protection block coincides with the orthographic projection of the first through hole of the screen body on the cover plate; more specifically, the outer edge of the orthographic projection of the first surface of the protection block on the cover plate coincides with the orthographic projection of the first through hole of the screen body on the cover plate. In this way, the first surface of the protection block contacts the portion of the metal layer exposed in the hole area, keeping the film layer below the metal layer flat, so that the metal layer can completely fit the film layer structure below, and improve the reliability of the display module.

[0046] In some embodiments, continue to refer to Figure 4 , the orthographic projection of the protection block on the cover plate is in the shape of a ring, the first edge 343 in the above embodiment is the outer boundary of the ring, and the second edge 344 is the inner boundary of the ring. Specifically, most of the hole area designs are currently circular. To adapt to such hole area designs, the protection block in this embodiment is correspondingly configured to fit the space formed by the expansion of the side wall of the screen body, and the inner diameter of the protection block (i.e., the diameter of the second edge 344) is adapted to the size of the hole area, thereby improving the reliability of the display module; and the inner side wall of the protection block can serve as the side wall inside the hole area, facilitating the subsequent arrangement of other devices or structures in the hole area.

[0047] When the display module is in use, air discharge may occur in the air inside the hole area, directly generating static electricity in the hole area. Therefore, in addition to protecting against static electricity outside the hole area, corresponding protection measures need to be set for static electricity generated inside the hole area.

[0048] Figure 5 FIG. 1 is a schematic diagram of the structure of a display module provided by an embodiment of the present disclosure. Figure 5 As shown, the side of the protection block 340 away from the screen body 320 includes a conductive portion 345. The conductive portion 345 extends from the metal layer 331 to the side of the cover plate 310 and is electrically connected to the metal layer 331. Exemplarily, when preparing the protection block 340, a conductive substance, such as metal particles, can be added to the side of the protection block 340 away from the screen body 320, and the part of the protection block 340 containing the conductive substance is used as the conductive portion 345.

[0049] In this embodiment, the conductive portion 345 of the protection block 340 is close to the hole area side, so when the static electricity in the hole area approaches the protection block 340, it will be introduced into the metal layer of the composite tape through the conductive portion 345 of the protection block 340, so that the static electricity cannot approach the edge of the screen body, thereby preventing the screen body from being affected by static electricity. Furthermore, because the conductive portion 345 covers the side wall of the hole area, the static electricity in the hole area can be promptly guided out through the conductive portion 345 when it approaches the side wall of the hole area from any direction, thereby improving the stability and reliability of the display module.

[0050] In this embodiment, the first surface of the protective block 340 can be connected to the metal layer 331 of the composite tape by a conductive adhesive; more specifically, the conductive part 345 is bonded to the metal layer 331 of the composite tape by a conductive adhesive. Exemplarily, the conductive adhesive is mainly composed of adhesives such as epoxy resin, polyimide resin, phenolic resin, and conductive particles such as copper and aluminum. Therefore, the conductive adhesive can achieve electrical connection between the conductive part 345 and the metal layer 331 while bonding the protective block 340 to the metal layer. The second surface of the protective block 340 can be fixed by a conductive adhesive or a non-conductive adhesive, and the present disclosure does not make specific restrictions on this.

[0051] Of course, the protective block 340 can also be mixed with conductive materials as a whole to reduce the difficulty of preparation. In this case, static electricity flows along the protective block 340 to the metal layer 331 with a smaller resistance, which can also prevent static electricity from entering the inside of the screen body 320 from the edge of the screen body 320.

[0052] Furthermore, the material of the protection block 340 includes a curing adhesive material mixed with a conductive substance. The conductive substance mixed in the curing adhesive can introduce static electricity into the metal layer 331 to protect the screen body 320 from static damage. The curing adhesive has good bonding properties, so the protection block 340 prepared using the curing adhesive material does not need to be fixed in the hole area by additional adhesive materials, simplifying the preparation process of the display module. At the same time, the cured adhesive can provide additional mechanical strength, especially when subjected to shear force or impact load, so as to achieve the protective effect of the protection block 340 on the metal layer 331 and the screen body 320, and prevent them from being damaged by external forces. In addition, the curing adhesive also has a sealing effect to prevent moisture and gas in the hole area from penetrating into the interior of the display module.

[0053] The above describes in detail the specific structure, material and fixing method of the protection block. The following will continue to introduce the specific structure of the composite tape with reference to the accompanying drawings.

[0054] Continue to refer Figure 1The composite tape is usually composed of a metal layer and a tape layer with good adhesion. The tape layer completely covers one side surface of the metal layer, and the edges of the tape layer and the metal layer are flush. The composite tape is adhered to one side surface of the underlying film layer through the tape layer. However, if the protective block in the above embodiment is directly bonded to the composite tape, the protective block will be adhered to the tape layer of the composite tape, and the material of the tape layer usually includes acrylic or rubber-based adhesives, etc., which have poor conductivity and will hinder the static electricity in the hole area from being introduced into the metal layer of the composite tape along the protective block. In order to avoid the above problems, another embodiment of the present disclosure makes corresponding improvements to the tape layer of the composite tape.

[0055] Figure 6 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present disclosure. Figure 6 As shown, the composite tape 330 also includes a tape layer 332. The tape layer 332 is located on the side of the metal layer 331 close to the screen body 320. The tape layer 332 includes a second opening 3321, and the orthographic projection of the first opening of the metal layer 331 on the cover plate 310 is located within the orthographic projection range of the second opening 3321 on the cover plate 310. Through the above arrangement, part of the metal layer 331 is directly exposed in the hole area, and this part of the metal layer 331 is in direct contact with the protection block 340 in the hole area, so as to prevent the tape layer 332 from affecting the static electricity in the hole area and being introduced into the metal layer 331 along the protection block 340.

[0056] In some embodiments, the orthographic projection of the second opening 3321 of the tape layer 332 on the cover plate 310 coincides with the orthographic projection of the first through hole of the screen body 320 on the cover plate 310. At this time, the portion of the composite tape 330 covering the screen body 320 is provided with the tape layer 332, and is bonded to the screen body 320 through the tape layer 332. The portion of the composite tape 330 not covering the screen body 320 is not provided with the tape layer 332, so that the area of ​​the metal layer 331 in direct contact with the protective block 340 (or bonded by conductive adhesive) can be increased, the conductive performance of the protective block 340 is improved, and the reliability of the display module structure is improved.

[0057] The following further describes other film layers that may be included in the display module in conjunction with the accompanying drawings.

[0058] Figure 7 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present disclosure. Figure 7 As shown, in addition to the structure described in the above embodiment, the display module also includes a support film layer 350 and a polarizer layer 360. Figure 7 The differences between the illustrated embodiment and the above-mentioned embodiment and the similarities thereof will not be described in detail.

[0059] The supporting film layer 350 is located on the side of the screen body 320 away from the cover plate 310, and the supporting film layer 350 includes a second through hole 351. The polarizer layer 360 is located on the side of the screen body 320 close to the cover plate 310, and the polarizer layer 360 includes a third through hole 361. The protection block 340 passes through the first through hole, the second through hole 351 and the third through hole 361 at the same time. Figure 1 In the display module shown in the present embodiment, the screen body 320 , the supporting film layer 350 and the polarizer layer 360 simultaneously expand outwards in a direction away from the hole area to provide a holding space for the protection block 340 .

[0060] The distance between the first surface and the second surface of the protection block 340 is equal to the distance between the surfaces of the metal layer and the cover plate 310 facing the first through hole. That is, in this embodiment, the height of the protection block 340 is approximately equal to the sum of the thicknesses of the screen body 320, the support film layer 350, and the polarizer layer 360. The protection block 340 can simultaneously cover the edges of the screen body 320, the support film layer 350, and the polarizer layer 360 at the hole area, protecting the edges of multiple film layers from being affected by the external environment, thereby improving the reliability of the display module.

[0061] In some embodiments, the orthographic projection of the second through hole 351 on the cover plate 310 coincides with the orthographic projection of the first through hole on the cover plate 310, and the orthographic projection of the third through hole 361 on the cover plate 310 coincides with the orthographic projection of the first through hole on the cover plate 310. That is, the orthographic projections of the edges of the screen body 320, the supporting film layer 350, and the polarizer layer 360 at the hole area position on the cover plate 310 coincide with each other. In this way, in the preparation process of the display module, multiple film layers can be punched at the same time, simplifying the preparation process, improving production efficiency, and reducing manufacturing costs.

[0062] Of course, in addition to the film layers described above, the display module may also include other film layer structures, and the present disclosure does not impose any specific limitation on this.

[0063] For example, in addition to the film layer described above, the display module may further include an optical adhesive layer. Figure 8 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present disclosure. Figure 8 As shown, the optical adhesive layer 370 is located on the side of the cover plate 310 close to the screen body 320, and the optical adhesive layer 370 includes a third opening 371. The optical adhesive layer 370 can bond the cover plate 310 and other film layers of the display module to ensure the stability and integrity of the display module structure. At the same time, the optical adhesive layer 370 has good optical properties to improve the display performance of the display module. Exemplarily, the material of the optical adhesive layer 370 may include acrylic glue, epoxy resin glue, silicone, etc.

[0064] In some embodiments, continue to refer to Figure 8, the orthographic projection of the third opening 371 on the cover plate 310 coincides with the orthographic projections of the first through hole, the second through hole, and the third through hole on the cover plate 310. That is, compared to Figure 1 In the display module shown in the embodiment, the screen body 320, the supporting film layer, the polarizer layer and the optical adhesive layer 370 simultaneously expand outward in a direction away from the hole area to provide a storage space for the protection block. In the embodiment, the first surface of the protection block contacts the metal layer of the composite tape, and the second surface of the protection block is bonded to the cover plate 310 through the adhesive material.

[0065] The following is a brief introduction to the preparation process of the display module provided by the above embodiment. In the preparation process, firstly, the supporting film layer, the screen body, the polarizer layer and other film layers are perforated; secondly, the optical adhesive layer is attached to one side of the polarizer layer and the optical adhesive layer is perforated; then, the cover plate is attached to the optical adhesive layer, and the protective block is attached to the cover plate; finally, the composite tape is attached to one side of the supporting film layer.

[0066] Alternatively, in other embodiments, since the optical adhesive layer is sticky, the optical adhesive layer can also be used to achieve bonding between the protection block and the cover plate. Fig. 9 As shown, the orthographic projection of the third opening 371 of the optical adhesive layer 370 on the cover plate 310 is located within the orthographic projection range of the first through hole on the cover plate 310, and the orthographic projection of the protection block on the cover plate 310 is located within the orthographic projection range of the optical adhesive layer 370 on the cover plate 310, and the protection block is in contact with the optical adhesive layer 370. That is, compared to Figure 1 In the display module shown in the embodiment, the screen body 320, the supporting film layer, the polarizer layer and the tape layer of the composite tape expand outwards in the direction away from the hole area, while the optical adhesive layer 370 and the metal layer of the composite tape shrink inwards in the direction of the hole area. Part of the optical adhesive layer 370 is exposed in the hole area, and the protective block is bonded to one side of the cover plate 310 through the part of the optical adhesive layer 370 exposed in the hole area.

[0067] The following is a brief introduction to the preparation process of the display module provided by the above embodiment. In the preparation process, firstly, the supporting film layer, the screen body, the polarizer layer and other film layers are perforated; secondly, the optical adhesive layer is attached to one side of the polarizer layer and the optical adhesive layer is perforated; then, the cover plate and the protective block are attached to both sides of the optical adhesive layer respectively; finally, the composite tape is attached to one side of the supporting film layer.
