Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0044] It should be understood that when a layer or element is referred to as being on another layer or substrate, it may be directly on the other layer or substrate, or there may be an intermediate layer between the layer or element and the other layer or substrate.

[0045] As one of the essential important components of a display product, the heat dissipation layer needs to be attached to the display panel to improve the heat dissipation performance of the display module.

[0046] However, with the development of display technology, the application fields of display devices are becoming more and more extensive, and people's requirements for various performances of display products are gradually increasing. This makes the heat dissipation performance of the heat dissipation layer in the current display module unable to meet the needs of higher-end display products. Therefore, how to improve the heat dissipation performance of the heat dissipation layer in a display product has become an urgent problem to be solved in the art.

[0047] In view of this, an embodiment of the present application proposes a bonding assembly, and the bonding assembly bonds to the display panel of the display module for functions such as heat dissipation and protection of the display module. Figure 1 Shows a schematic diagram of the hierarchical structure of a bonding assembly proposed in an embodiment of the present application, as Figure 1 shown, the bonding assembly 11 includes: at least one functional layer; removable first protective film 111 and second protective film 112, and the first protective film 111 and the second protective film 112 are disposed on opposite sides of the functional layer.

[0048] In the embodiments of the present application, the first protective film 111 and the second protective film 112 are used to protect the functional layer from physical damage (such as scratches, abrasions or impacts, etc.) and effectively prevent dust contamination and electromagnetic wave shielding when the bonding component 11 is not bonded to the display panel, so as to maintain the cleanliness and stability of each functional layer in the bonding component 11. Among them, since the bonding component 11 needs to be bonded to the display panel, the bonding surface of the bonding component 11 needs to be fixedly connected to the display panel through the functional layer. In the embodiments of the present application, the first protective film 111 and the second protective film 112 are configured as removable film layers on the bonding component 11. During the bonding process, by removing the protective film on one side, it is ensured that the bonding surface of the functional layer and the display panel are successfully fixedly connected.

[0049] In addition, in the embodiments of the present application, by providing the removable first protective film 111 and the second protective film 112, the occurrence of defects such as degumming, residual glue, bubbles, fogging, and dirt can be reduced during the bonding process, ensuring that the bonding effect reaches the best state, which helps to improve the overall quality and user experience of the display product.

[0050] In some alternative embodiments, in order to ensure the protective effect of the first protective film 111 and the second protective film 112 on the functional layer, the areas of the first protective film 111 and the second protective film 112 are the same, and the orthographic projection area of the functional layer on the first protective film 111 is smaller than the area of the first protective film 111.

[0051] In the embodiments of the present application, the functional layer can be one (as Figure 1 shown). When the functional layer is one, the functional layer includes a heat dissipation layer 113. When the functional layer is multiple, the functional layer at least includes the heat dissipation layer 113. The heat dissipation layer 113 is configured to improve the heat dissipation efficiency of the display module, reduce the temperature of the display module, and prevent the electronic components in the display module from having reduced lifespan and performance due to excessive temperature.

[0052] In the embodiments of the present application, Figure 3 shows a schematic diagram of a composite material of graphene and carbon nanotubes proposed in an embodiment of the present application, as Figure 3As shown, the material of the heat dissipation layer 113 is a composite material of graphene 1131 and carbon nanotubes 1132. Specifically, the thermal conductivity of single-layer graphene is as high as 5300 W / (m·K), which is one of the materials with the best thermal conductivity among currently known materials. Its high thermal conductivity mainly benefits from its unique two-dimensional structure and perfect lattice arrangement, enabling heat to be quickly conducted within the plane. Carbon nanotubes also have excellent thermal conductivity. Especially for single-walled carbon nanotubes, their thermal conductivity at room temperature can reach 6000 W / m·K, and that of multi-walled carbon nanotubes can also reach about 3000 W / m·K. The one-dimensional structure of carbon nanotubes gives them extremely high thermal conductivity in the axial direction. When graphene and carbon nanotubes combine to form a composite material, the two can cooperate with each other. The heat absorbed by graphene 1131 can be transmitted more quickly to another graphene 1131 in the heat dissipation layer 113 through carbon nanotubes 1132, thereby ensuring that heat is quickly conducted from the inside of the heat dissipation layer 113 to the surface and then dissipated through the thermal radiation of graphene 1131, further improving the overall thermal conductivity of the heat dissipation layer 113. Compared with the thermal conductivity of pure graphene, the heat dissipation layer 113 made of the composite material of graphene 1131 and carbon nanotubes 1132 can increase the thermal conductivity by 2.5 times.

[0053] In addition, when the composite material of graphene 1131 and carbon nanotubes 1132 is used as the heat dissipation layer 113, it can also greatly improve the electrical conductivity of the heat dissipation layer 113.

[0054] In some optional embodiments, Figure 6 shows a preparation flow chart of a composite material of graphene and carbon nanotubes proposed in an embodiment of the present application. As Figure 6 shown, the composite material of graphene and carbon nanotubes can be prepared as follows: Obtain a graphene solution and a carbon nanotube solution, and the concentrations of both the graphene solution and the carbon nanotube solution are 2 mg / ml; ultrasonically mix the graphene solution and the carbon nanotube solution in a mass ratio of 2:1 to obtain a mixed solution; place the mixed solution in a reaction kettle and carry out a hydrothermal reaction in a high-temperature furnace to obtain a hydrogel. Among them, the reaction conditions for the hydrothermal reaction are a temperature of 180 °C and a time of 12 h; take out the hydrogel formed by the high-temperature hydrothermal reaction and place it in a freeze dryer for freezing for 12 h, then the dryer is evacuated for drying. After taking it out, place the aerogel in a hot press for hot pressing treatment, with a pressure of 70 MPa, a temperature of 70 °C, and a time of 6 h. After the aerogel is hot-pressed into an aerogel film, take it out and place it in a tube furnace for annealing treatment at 1000 K to obtain the composite material of graphene and carbon nanotubes.

[0055] In the embodiment of the present application, the bonding component 11 provided is an integrated component. When there are multiple functional layers, the multiple functional layers are stacked, and adjacent functional layers are configured to be in direct contact with each other. Specifically, during the manufacturing process, the bonding component 11 directly pre-assembles multiple functional layers to form an integrated structure. Therefore, when forming each functional layer, there is no need to provide additional protective films formed on the opposite sides of the surface of each functional layer. Only after all functional layers are formed, the first protective film 111 and the second protective film 112 are provided on the opposite sides of the functional layer, thus avoiding the process of setting additional protective films on the opposite sides of each functional layer due to split assembly, significantly reducing the production steps and the number of protective films, simplifying the production process, thereby improving production efficiency and reducing production and material transportation costs.

[0056] In some alternative embodiments, Figure 2 shows a schematic diagram of the hierarchical structure of another bonding component proposed in an embodiment of the present application, as Figure 2 shown, the functional layer further includes a metal layer 114, and the metal layer 114 is disposed between the heat dissipation layer 113 and the first protective film 111. Optionally, the material of the metal layer 114 is copper foil. The metal layer 114 is used to provide mechanical support and stability for the display panel to ensure the structural performance of the display panel. At the same time, it is used to quickly conduct the heat generated during the light-emitting process of the display panel to the heat dissipation layer 113, improving the durability and performance of the display panel; in addition, the metal layer 114 is also used for electromagnetic shielding, and effectively absorbs electromagnetic waves through the metal layer 114, thereby achieving the effect of shielding interference, and further ensuring the normal operation of the display product. The electromagnetic shielding includes two types: electrical signal shielding and magnetic signal shielding. Exemplarily, when the material of the metal layer 114 is copper foil, the electrical signal shielding mainly relies on the excellent electrical conductivity of copper itself, while the magnetic shielding requires the conductive substance "nickel" on the adhesive surface of the copper foil tape to achieve the magnetic shielding effect. Among them, the purity of the copper foil is higher than 99.95%, and its function is to eliminate electromagnetic interference (EMI), isolate the harm of electromagnetic waves to the human body, and avoid affecting the function due to unnecessary voltage and current.

[0057] In some alternative embodiments, the functional layer further includes a first bonding layer 115, and the first bonding layer 115 is disposed between the metal layer 114 and the heat dissipation layer 113. The first bonding layer 115 is configured to achieve the fixed connection between the metal layer 114 and the heat dissipation layer 113. Optionally, the material of the first bonding layer 115 is double-sided tape.

[0058] In some alternative embodiments, the functional layer further includes a buffer layer 117 disposed between the heat dissipation layer 113 and the second protective film 112. The buffer layer 117 has a certain deformation ability and hardness, and is used to disperse the adverse effects on the display panel caused by stress through the deformation ability when the display module is affected by external stress due to foreign objects or the external environment, and at the same time plays a certain supporting and protecting role. Optionally, the material of the buffer layer 117 is foam.

[0059] In some alternative embodiments, the functional layer further includes a second adhesive layer 116 disposed between the buffer layer 117 and the heat dissipation layer 113. The second adhesive layer 116 is configured to achieve the fixed connection between the buffer layer 117 and the heat dissipation layer 113. Optionally, the material of the second adhesive layer 116 is double-sided tape.

[0060] In some alternative embodiments, the functional layer further includes a reticulated adhesive layer 118 disposed between the buffer layer 117 and the second protective film 112. The reticulated adhesive layer 118 is configured to achieve the fixed connection between the buffer layer 117 and the second protective film 112.

[0061] Exemplarily, such as Figure 2As shown, the bonding assembly 11 includes a plurality of functional layers, and the plurality of functional layers include: a heat dissipation layer 113, which is a composite material of graphene and carbon nanotubes; a metal layer 114, which is disposed between the heat dissipation layer 113 and the first protective film 111; a first bonding layer 115, which is disposed between the metal layer 114 and the heat dissipation layer 113; a buffer layer 117, which is disposed between the heat dissipation layer 113 and the second protective film 112; a second bonding layer 116, which is disposed between the buffer layer 117 and the heat dissipation layer 113; and a reticulated adhesive layer 118, which is disposed between the buffer layer 117 and the second protective film 112. In the embodiment of the present application, by providing an integrated bonding assembly 11, adjacent functional layers are configured to be in direct contact with each other, and no protective film needs to be provided between adjacent functional layers. Compared with separately disposing each functional layer, in the integrated bonding assembly 11 provided in the embodiment of the present application, only the first protective film 111 disposed on the side of the metal layer 114 away from the heat dissipation layer 113 and the second protective film 112 disposed on the side of the reticulated adhesive layer 118 away from the heat dissipation layer 113 need to be retained, and the protective film on the side of the metal layer 114 close to the heat dissipation layer 113, the protective film on the side of the reticulated adhesive layer 118 close to the heat dissipation layer 113, the protective films on the opposite sides of the buffer layer 117, and the protective films on the opposite sides of the heat dissipation layer are omitted, reducing a total of 6 layers of protective film formation, significantly reducing the production steps and the number of protective films, simplifying the production process, thereby improving the production efficiency and reducing the production and material transportation costs.

[0062] The embodiment of the present application provides a bonding assembly, a display module, and a display device. The bonding assembly includes: at least one functional layer. When there are a plurality of functional layers, the plurality of functional layers are stacked, and adjacent functional layers are configured to be in direct contact with each other; a removable first protective film and a second protective film, which are disposed on opposite sides of the functional layer; wherein, the functional layer includes a heat dissipation layer, and the heat dissipation layer is a composite material of graphene and carbon nanotubes. In the embodiment of the present application, by setting the material of the heat dissipation layer as a composite material of graphene and carbon nanotubes, after the heat dissipation layer absorbs heat, the heat of the graphene sheet can be transmitted to another graphene sheet more quickly through the carbon nanotubes, thereby effectively improving the heat dissipation performance of the heat dissipation layer.
