Description

Technical Field

[0001] This disclosure relates to the field of display technology, specifically to a display module and electronic device. Background Technology

[0002] To achieve a high screen-to-body ratio, electronic devices typically incorporate punch-hole areas in their display modules to house cameras, sensors, and other components. However, in these punch-hole designs, the display module's screen body is exposed. The exposed edges of the screen are susceptible to damage from external forces, leading to cracks and other defects, resulting in a series of problems related to the punch-hole area. Furthermore, when static electricity exists within the punch-hole area, it can be conducted from the screen edges, causing electrostatic damage and affecting display quality and lifespan. Summary of the Invention

[0003] In view of this, the present disclosure provides a display module and electronic device to solve the problem that the screen body at the hole area is easily damaged by external force and electrostatic discharge in the related art.

[0004] The first aspect of this disclosure provides a display module, including: a cover plate; a screen body located on one side of the cover plate, the screen body including a first through hole; a composite tape located on the side of the screen body away from the cover plate, the composite tape including a metal layer, the metal layer including a first opening, the orthographic projection of the first opening on the cover plate being within the orthographic projection range of the first through hole on the cover plate; and a protective block located inside the first through hole, covering the sidewall of the first through hole and contacting the metal layer.

[0005] In some embodiments, the orthographic projection of the protective block on the cover plate is located between the orthographic projections of the first opening and the first through hole on the cover plate. The protective block includes a first surface and a second surface disposed opposite to each other. The first surface is bonded to the metal layer, and the second surface is bonded to the cover plate. Preferably, the first surface is bonded to the metal layer by conductive adhesive.

[0006] In some embodiments, the side of the protective block away from the screen includes a conductive portion, which is electrically connected to the metal layer.

[0007] In some embodiments, the orthographic projection of the protective block on the cover plate includes a first edge and a second edge, the second edge being located within the first edge, and the second edge coinciding with the orthographic projection of the first opening on the cover plate; preferably, the first edge coincides with the orthographic projection of the first through hole on the cover plate.

[0008] In some embodiments, the orthographic projection of the protective block onto the cover plate is annular, with the first edge being the outer boundary of the annulus and the second edge being the inner boundary of the annulus.

[0009] In some embodiments, the composite tape further includes a tape layer located on the side of the metal layer near the screen body; the tape layer includes a second opening, and the orthographic projection of the first opening on the cover plate is within the orthographic projection range of the second opening on the cover plate; preferably, the orthographic projection of the second opening on the cover plate coincides with the orthographic projection of the first through hole on the cover plate.

[0010] In some embodiments, the material of the protective block includes a cured adhesive material mixed with conductive substances.

[0011] In some embodiments, the display module further includes an optical adhesive layer located on the side of the cover plate near the screen body. The optical adhesive layer includes a third opening, the orthographic projection of the third opening on the cover plate is within the orthographic projection range of the first through hole on the cover plate, the orthographic projection of the protective block on the cover plate is within the orthographic projection range of the optical adhesive layer on the cover plate, and the protective block and the optical adhesive layer are in contact.

[0012] In some embodiments, the display module further includes: a support film layer located on the side of the screen away from the cover plate, the support film layer including a second through hole; a polarizer layer located on the side of the screen close to the cover plate, the polarizer layer including a third through hole, and a protective block penetrating through the second through hole and the third through hole; preferably, the orthographic projection of the second through hole on the cover plate coincides with the orthographic projection of the first through hole on the cover plate, and the orthographic projection of the third through hole on the cover plate coincides with the orthographic projection of the first through hole on the cover plate.

[0013] The second aspect of this disclosure provides an electronic device including the display module provided in the first aspect above.

[0014] In the display module disclosed herein, by indenting the metal layer in the composite tape towards the hole area, it completely covers the edge of the screen at the hole area, providing protection for the screen. This also prevents static electricity from entering the hole area and then entering the screen from the edge, improving the display effect and preventing electrostatic damage to the screen. The protective block supports the metal layer, preventing deformation under external forces. Simultaneously, the protective block covers the edge of the screen, protecting it from external damage and environmental influences, thus improving the reliability of the display module.

[0025] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this specification.

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

[0027] In related technologies, to increase the screen-to-body ratio of electronic devices, a punch-hole design is usually made in the display area. Figure 1The diagram shows a schematic representation of the hole area in a display module in related technologies. Figure 1 As shown, to achieve the hole-punch design of the display area, through holes H are usually opened in multiple film layers of the display module. As described in the background art, during the process of hollowing out the screen body 11 in the display module to form through holes H, the edge of the hollowed-out position of the screen body 11 is exposed, making the exposed screen edge susceptible to damage from external forces, resulting in cracks and other abnormalities.

[0028] In addition, static electricity may exist inside the through hole H during the use of the display module. The static electricity may enter the screen body 11 from the edge of the through hole H, which may affect the display effect or even cause static damage to the screen body, thus affecting the service life of the display module.

[0029] In view of the above, this disclosure provides a display module, including: a cover plate; a screen body located on one side of the cover plate, the screen body including a first through hole; a composite tape located on the side of the screen body away from the cover plate, the composite tape including a metal layer, the metal layer including a first opening, the orthographic projection of the first opening on the cover plate being within the orthographic projection range of the first through hole on the cover plate; and a protective block located inside the first through hole, covering the sidewall 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, as well as prevent external static electricity from entering the hole area; the protective block covers the exposed edges of the screen to provide protection, and the protective block can also provide support for the relatively soft metal layer to prevent its deformation. In this way, the problems of external force damage and static electricity damage caused by exposed screen edges in the hole area can be solved, improving the reliability and display effect of the display module.

[0031] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0032] Figure 2 The image shown is a top view of a display module provided in an embodiment of this disclosure. Figure 2 As shown, the display module includes a display area AA and a non-display area surrounding the display area AA. The display area AA has a perforated area H. By drilling holes in multiple film layers below the perforated area H, through-holes are formed, allowing for the placement of devices such as cameras and sensors within the perforated area H.

[0033] Figure 3 As shown Figure 2 The diagram shows a partial structural diagram of the film layer in region B of the display module. Figure 3 As shown, the display module includes a cover plate 310, a screen body 320, a composite tape 330, and a protective 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 hole area as in related technologies, the opening area of ​​the first through hole 321 of the screen body 320 in this embodiment is relatively increased.

[0035] A composite adhesive tape 330 is disposed on the side of the screen body 320 away from the cover plate 310. The composite adhesive 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 or aluminum.

[0036] In related technologies, continue to refer to Figure 1 The composite tape 12 at the hole area cannot completely cover the underlying film structure. In this embodiment, the metal layer 331 is recessed into the hole area so that it can completely wrap around the underlying screen 320, thereby protecting the edge of the screen 320. Since the metal layer 331 is conductive, it can prevent static electricity from outside the hole area from entering the hole area, thus preventing external static electricity from entering the screen 320 along the edge of the first through hole 321 and causing electrostatic damage to the screen 320.

[0037] The protective block 340 is located within the first through hole 321 of the screen body 320. The protective block 340 covers the sidewall of the first through hole 321. In this way, the protective block 340 can protect the edge of the screen body 320 at the hole area, preventing damage caused by external forces; at the same time, it can also protect the screen body 320 from the influence of the external environment. It is understood that the outer sidewall of the protective block 340 may or may not contact the sidewall of the first through hole 321; the protective block 340 only needs to cover the edge of the screen body 320 exposed within the hole area to achieve the protection function of the screen body 320 edge.

[0038] Because the metal layer 331 is relatively soft, it is easily deformed by external forces, which can cause pressure on the screen 320 below. Therefore, one side of the protective block 340 can be in contact with the metal layer 331, so that the protective block 340 can provide support for the metal layer 331. For example, the protective block 340 can be bonded to the metal layer 331, which can protect the screen 320 and the metal layer 331 while also fixing the protective block 340, thereby improving the reliability of the display module.

[0039] In this embodiment, the display module protects the screen by indenting the metal layer in the composite tape towards the hole area, completely enveloping the screen edge at the hole location. This prevents static electricity from entering the hole area and then entering the screen from the edge, improving the display effect and preventing electrostatic damage to the screen. The protective block supports the metal layer, preventing deformation under external forces. Simultaneously, the protective block covers the screen edge, protecting the screen from external damage and environmental influences, thus improving the reliability of the display module.

[0040] The specific structure of the protective block will be further described below with reference to the accompanying drawings.

[0041] In some embodiments, continue to refer to Figure 3 The protective block 340 includes a first surface 341 and a second surface 342 disposed 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 protective block 340 is bonded to the surface of the metal layer 331 facing the first through hole 321, and the second surface 342 of the protective block 340 is bonded to the surface of the cover plate 310 facing the first through hole 321, so as to fix the protective block 340 between the cover plate 310 and the metal layer 331 and prevent it from being displaced by external forces.

[0042] For example, the protective block 340 can be bonded to the metal layer 331 and / or the cover plate 310 by adhesive material, or the protective block 340 can be prepared directly using a curable adhesive material.

[0043] The orthographic projection of the protective block 340 on the cover plate 310 is located between the orthographic projections of the first opening 3311 and the first through hole 321 on the cover plate 310; the distance between the first surface 341 and the second surface 342 of the protective 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 protective block 340 abuts against the cover plate 310 and the metal layer 331 respectively, so that the protective block 340 can support the metal layer 331, prevent the metal layer 331 from being too soft and deformed, and improve the reliability of the display module.

[0044] Figure 4 As shown Figure 2 The diagram shows a magnified view of a portion of the display module in area B. Figure 4As shown, the orthographic projection of the protective block onto the cover plate includes a first edge 343 (represented by a dashed line) and a second edge 344 (represented by a solid line), with the second edge 344 located within the first edge 343. The second edge 344 coincides with the orthographic projection of the first opening of the metal layer onto the cover plate; more specifically, the inner edge of the orthographic projection of the first surface of the protective block onto the cover plate coincides with the orthographic projection of the first opening of the metal layer onto the cover plate. This ensures that the protective block supports the edge of the metal layer at the hole location, preventing deformation of the first opening of the metal layer due to external forces, thus avoiding impact on the opening shape of the hole area and the normal operation of devices within the hole area.

[0045] In some embodiments, the first edge of the protective block coincides with the orthographic projection of the first through-hole of the screen onto the cover plate; more specifically, the outer edge of the orthographic projection of the first surface of the protective block onto the cover plate coincides with the orthographic projection of the first through-hole of the screen onto the cover plate. In this way, the first surface of the protective block contacts the portion of the metal layer exposed in the hole area, keeping the film layer beneath the metal layer flat, allowing the metal layer to fully adhere to the underlying film layer structure, and improving the reliability of the display module.

[0046] In some embodiments, continue to refer to Figure 4 The protective block's orthographic projection onto the cover plate is circular. In the above embodiment, the first edge 343 is the outer boundary of the ring, and the second edge 344 is the inner boundary of the ring. Specifically, most current hole area designs are circular. To accommodate such hole area designs, the protective block in this embodiment is correspondingly designed to fit the space formed by the outward expansion of the screen sidewall. Furthermore, the inner diameter of the protective block (i.e., the diameter of the second edge 344) is adapted to the size of the hole area, improving the reliability of the display module. In addition, the inner sidewall of the protective block can serve as the sidewall inside the hole area, facilitating the subsequent installation of other devices or structures within the hole area.

[0047] During the use of the display module, air discharge may occur inside the aperture area, generating static electricity directly within the aperture area. Therefore, in addition to protecting against static electricity outside the aperture area, appropriate protective measures are also needed for the static electricity generated inside the aperture area.

[0048] Figure 5 The diagram shown is a structural schematic of a display module provided in an embodiment of this disclosure. Figure 5 As shown, the protective block 340 includes a conductive portion 345 on the side away from the screen 320. The conductive portion 345 extends from the metal layer 331 toward the cover plate 310 and is electrically connected to the metal layer 331. Exemplarily, when manufacturing the protective block 340, a conductive material, such as metal particles, can be incorporated into the side of the protective block 340 away from the screen 320, and the portion of the protective block 340 containing the conductive material serves as the conductive portion 345.

[0049] In this embodiment, the conductive portion 345 of the protective block 340 is close to the hole area side. Therefore, when static electricity in the hole area approaches the protective block 340, it will be conducted into the metal layer of the composite tape through the conductive portion 345 of the protective block 340, preventing static electricity from approaching the edge of the screen and avoiding the screen from being affected by static electricity. Furthermore, since the conductive portion 345 covers the sidewall of the hole area, static electricity in the hole area can be discharged in a timely manner through the conductive portion 345 when it approaches the sidewall of the hole area from any direction, 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 using conductive adhesive; more specifically, the conductive part 345 is bonded to the metal layer 331 of the composite tape using conductive adhesive. Exemplarily, the conductive adhesive mainly consists of adhesives such as epoxy resin, polyimide resin, and phenolic resin, as well as conductive particles such as copper and aluminum. Therefore, while bonding the protective block 340 to the metal layer, the conductive adhesive can also achieve an electrical connection between the conductive part 345 and the metal layer 331. The second surface of the protective block 340 can be fixed with conductive or non-conductive adhesive; this disclosure does not impose specific limitations on this.

[0051] Of course, the protective block 340 can also be entirely mixed with conductive material to reduce the difficulty of manufacturing. In this case, static electricity flows along the protective block 340 to the metal layer 331 with lower resistance, which can also prevent static electricity from entering the interior of the screen 320 from the edge of the screen 320.

[0052] Furthermore, the protective block 340 is made of a curing adhesive material mixed with conductive substances. The conductive substances mixed in the curing adhesive can conduct static electricity into the metal layer 331 to protect the screen 320 from electrostatic damage. The curing adhesive has good adhesive properties, so the protective block 340 made using the curing adhesive material does not need to be fixed to the hole area position with additional adhesive, simplifying the manufacturing 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, to achieve the protective function of the protective block 340 for the metal layer 331 and the screen 320, preventing them from being damaged by external forces. In addition, the curing adhesive also has a sealing effect, preventing moisture and gas in the hole area from penetrating into the interior of the display module.

[0053] The above details the specific structure, material, and fixing method of the protective block. The following section, with reference to the attached diagram, will further describe the specific structure of the composite tape.

[0054] Continue to refer to Figure 1Composite tape typically consists of a metal layer and an adhesive layer with good adhesion. The adhesive layer completely covers one side of the metal layer, and the edges of the adhesive layer and the metal layer are flush. The composite tape adheres to one side of the underlying film layer via the adhesive layer. However, if the protective block in the above embodiment is directly adhered to the composite tape, it will cause the protective block to adhere to the adhesive layer of the composite tape. The material of the adhesive layer typically includes acrylic or rubber-based adhesives, which have poor conductivity and will hinder the conduction of static electricity in the hole area along the protective block into the metal layer of the composite tape. To avoid the above problems, another embodiment of this disclosure makes corresponding improvements to the adhesive layer of the composite tape.

[0055] Figure 6 The diagram shown is a structural schematic of a display module provided in another embodiment of this 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 near the screen 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 within the orthographic projection range of the second opening 3321 on the cover plate 310. Through the above arrangement, a portion of the metal layer 331 is directly exposed in the hole area, and this portion of the metal layer 331 is in direct contact with the protective block 340 in the hole area, preventing the tape layer 332 from affecting the static electricity in the hole area and conducting it into the metal layer 331 along the protective block 340.

[0056] In some embodiments, the orthographic projection of the second opening 3321 of the tape layer 332 onto the cover plate 310 coincides with the orthographic projection of the first through hole of the screen body 320 onto the cover plate 310. In this case, the portion of the composite tape 330 covering the screen body 320 has the tape layer 332, and is bonded to the screen body 320 via the tape layer 332. The portion of the composite tape 330 not covering the screen body 320 does not have the tape layer 332. Therefore, the area of ​​direct contact (or bonding via conductive adhesive) between the metal layer 331 and the protective block 340 can be increased, improving the conductivity of the protective block 340 and simultaneously enhancing the reliability of the display module structure.

[0057] The following section, with reference to the accompanying drawings, continues to describe other film layers that may be included in the display module.

[0058] Figure 7 The diagram shown is a structural schematic of a display module provided in another embodiment of this disclosure. Figure 7 As shown, in addition to the structure described in the above embodiments, the display module also includes a support film layer 350 and a polarizer layer 360. The following will focus on describing these aspects. Figure 7 The differences between the illustrated embodiments and the above embodiments are not repeated here.

[0059] The support film layer 350 is located on the side of the screen body 320 away from the cover plate 310, and the support film layer 350 includes a second through hole 351. The polarizing film layer 360 is located on the side of the screen body 320 closer to the cover plate 310, and the polarizing film layer 360 includes a third through hole 361. The protective block 340 passes through the first through hole, the second through hole 351, and the third through hole 361. Compared to Figure 1 In the display module shown, in this embodiment, the screen 320, the support film layer 350, and the polarizer layer 360 simultaneously expand outwards in a direction away from the hole area, providing a space for the protective block 340.

[0060] The distance between the first and second surfaces of the protective 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 protective block 340 is approximately equal to the sum of the thicknesses of the screen 320, the support film layer 350, and the polarizing film layer 360. The protective block 340 can simultaneously cover the edges of the screen 320, the support film layer 350, and the polarizing film layer 360 at the hole location, protecting the edges of multiple film layers from external environmental influences and 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 support film layer 350, and the polarizer layer 360 at their respective hole locations on the cover plate 310 coincide with each other. In this way, during the manufacturing process of the display module, multiple film layers can be perforated simultaneously, simplifying the manufacturing 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 this disclosure does not impose any specific limitations on this.

[0063] For example, in addition to the film layers described above, the display module may also include an optical adhesive layer. Figure 8 The diagram shown is a structural schematic of a display module provided in another embodiment of this disclosure. Figure 8 As shown, the optical adhesive layer 370 is located on the side of the cover plate 310 near the screen body 320, and includes a third opening 371. The optical adhesive layer 370 can bond the cover plate 310 and other film layers of the display module, ensuring the stability and integrity of the display module structure. Simultaneously, 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 adhesive, epoxy resin adhesive, silicone, etc.

[0064] In some embodiments, continue to refer to Figure 8The orthographic projection of the third opening 371 onto the cover plate 310 coincides with the orthographic projections of the first through hole, the second through hole, and the third through hole onto the cover plate 310. That is, compared to... Figure 1 In the display module shown, in this embodiment, the screen 320, the support film layer, the polarizing film layer, and the optical adhesive layer 370 simultaneously expand outwards in a direction away from the hole area, providing a space to accommodate the protective block. In this embodiment, the first surface of the protective block is in contact with the metal layer of the composite adhesive tape, and the second surface of the protective block is bonded to the cover plate 310 by adhesive material.

[0065] The following is a brief description of the fabrication process of the display module provided in the above embodiments. During the fabrication process, firstly, holes are drilled in the supporting film layer, screen body, polarizer layer, and other film layers; secondly, an optical adhesive layer is attached to one side surface of the polarizer layer, and holes are drilled in the optical adhesive layer; next, a cover plate is attached to the optical adhesive layer, and a protective block is attached to the cover plate; finally, composite tape is attached to one side surface of the supporting film layer.

[0066] Alternatively, in some other embodiments, the optical adhesive layer can also be used to bond the protective block to the cover plate because of its adhesive properties. For example... Figure 9 As shown, the orthographic projection of the third opening 371 of the optical adhesive layer 370 onto the cover plate 310 is within the orthographic projection range of the first through hole onto the cover plate 310. The orthographic projection of the protective block onto the cover plate 310 is within the orthographic projection range of the optical adhesive layer 370 onto the cover plate 310, and the protective block and the optical adhesive layer 370 are in contact. That is, compared to Figure 1 In the display module shown, in this embodiment, the screen 320, the support film layer, the polarizer layer, and the adhesive layer of the composite adhesive tape extend outwards away from the hole area, while the optical adhesive layer 370 and the metal layer of the composite adhesive tape retract inwards towards the hole area. A portion of the optical adhesive layer 370 is exposed within the hole area, and the protective block is bonded to one side of the cover plate 310 via the portion of the optical adhesive layer 370 exposed within the hole area.

[0067] The following is a brief description of the manufacturing process of the display module provided in the above embodiments. In the manufacturing process, firstly, holes are drilled in the supporting film layer, screen body, polarizer layer, and other film layers; secondly, an optical adhesive layer is attached to one side surface of the polarizer layer, and holes are drilled in the optical adhesive layer; then, the cover plate and protective block are respectively attached to both sides of the optical adhesive layer; finally, composite tape is attached to one side surface of the supporting film layer.

[0068] As can be seen, compared with the preparation process in the above embodiments, the optical adhesive layer can simultaneously bond the protective block during the cover plate bonding process. Therefore, there is no need to use additional adhesive to bond the protective block to the cover plate, which improves production efficiency and reduces manufacturing costs.

[0069] Based on the same inventive concept, this disclosure also provides an electronic device, including the display module provided in the above embodiments of this disclosure. In the embodiments of this disclosure, the electronic device may include a mobile phone, tablet computer, smart wearable device, television, laptop computer, monitor, or other device with display functionality. This disclosure does not impose specific limitations on the specific form of the electronic device.
