Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and more specifically, relates to a display module and its manufacturing method, and a display device. Background Technology

[0002] In related technologies, the display module, as the core component of the display device, can effectively display images or text. However, its design usually focuses more on optimizing display performance (such as resolution, brightness, response speed, etc.) and relatively neglects fire resistance performance. Summary of the Invention

[0003] The purpose of this application is to provide a display module and its manufacturing method, as well as a display device, in order to solve the technical problem of insufficient fire resistance of display modules in related technologies.

[0004] To achieve the above objectives, according to one aspect of this application, a display module is provided, comprising: a fireproof transparent component having a display surface and a mounting surface disposed opposite to each other; a light-emitting component disposed on the mounting surface; a control component located on the side of the light-emitting component away from the display surface and electrically connected to the light-emitting component; and the light-emitting component being mounted on the control component.

[0005] The fire-resistant transparent component provides direct fire protection for the light-emitting and control components, reducing the risk of the display module igniting due to external fire sources or high temperatures. Simultaneously, because the light-emitting component is directly mounted on the mounting surface of the fire-resistant transparent component, this structural design ensures that the light emitted by the component propagates directly from one side of the mounting surface to the other side of the display surface, helping to reduce optical path loss at the medium interface during light propagation. This not only enhances the display effect but also reduces the power consumption of the display module to some extent. Furthermore, the fire-resistant transparent component protects the light-emitting and control components, reducing the risk of scratches or damage, and eliminates the need for additional protective covers, thereby reducing the number of components in the display module and lowering costs. Additionally, the control component serves to support and mount the light-emitting and fire-resistant transparent components.

[0006] Optionally, the display module further includes a first connector and a second connector electrically connected to each other. The first connector is disposed on the light-emitting element and electrically connected to the light-emitting element; the second connector is disposed on the control element and electrically connected to the control element.

[0007] The first and second connectors, used in conjunction, not only establish an electrical connection channel between the light-emitting and control components, acting as a connecting bridge, but also allow for rapid fault location by individually testing the first and second connectors when an electrical connection fault occurs in the display module. This simplifies the troubleshooting process and improves maintenance efficiency and convenience. Furthermore, the first and second connectors can be configured with different types of mating components according to the actual needs of the display module, broadening the design flexibility and scenario adaptability of the display module.

[0008] Optionally, the light-emitting element includes a plurality of light-emitting bodies spaced apart; the first connector includes a plurality of first connectors, the number of which is twice the number of light-emitting bodies, and two first connectors electrically connected to the light-emitting bodies are spaced apart on the surface of the light-emitting body away from the display surface; the second connector includes a plurality of second connectors, the number of which is twice the number of light-emitting bodies, and the plurality of second connectors are spaced apart on the surface of the control element near the light-emitting element, and are electrically connected to the plurality of first connectors one-to-one.

[0009] On the one hand, each light-emitting element is equipped with two first connectors, and each of the two first connectors is electrically connected to two corresponding second connectors. This structural design allows current to be more evenly distributed to the light-emitting element, reducing current concentration caused by single-point connections, thereby reducing the risk of local overheating or brightness decay of the light-emitting element. Simultaneously, stable current transmission can reduce brightness and color temperature deviations between different light-emitting elements, effectively improving the uniformity of the display module's image. On the other hand, each light-emitting element achieves independent power supply and electrical signal transmission through its corresponding two first connectors and two second connectors, ensuring that the working circuits of each light-emitting element do not interfere with each other. When a single light-emitting element fails, the remaining light-emitting elements can still operate normally, maximizing the overall luminous effect and display function of the display module; furthermore, during maintenance, it is not necessary to replace the entire light-emitting component, but only to replace the faulty light-emitting element, first connector, or second connector, thereby reducing maintenance difficulty and cost. On the other hand, when the light emitter malfunctions, the source of the fault can be quickly determined by detecting the on / off status of its two corresponding first connectors: if both first connectors are disconnected, the light emitter itself may be faulty; if only a single first connector is disconnected, only the faulty first connector needs to be replaced, without replacing the entire light emitter or control components, thereby shortening maintenance time and reducing costs.

[0010] Optionally, one of the first connector and the second connector is provided with a connection structure, and the first connector and the second connector are kept in contact with the connection structure and electrically connected; and / or, one of the first connector and the second connector is a connection electrode, and the other is a connection pad.

[0011] The designed connection structure not only enables the first and second connectors to connect, but also ensures that both connectors remain firmly pressed against the connection structure. This design offers several advantages: First, it allows the first and second connectors to apply continuous pressure to the connection structure, ensuring a tight fit between their contact surfaces, effectively eliminating minute gaps, reducing contact resistance, and minimizing signal attenuation during current transmission. Second, the static pressure generated by the tight fit prevents the connection points between the first and second connectors and the connection structure from loosening or separating due to vibration or impact, thus improving the stability and reliability of the connection.

[0012] The matching connecting electrodes and pads not only enable automatic positioning and reduce assembly errors, but also allow the protruding shape of the connecting electrodes to form a tight contact with the connecting pads, thereby increasing the effective conductive area, reducing contact resistance, and ensuring stable transmission of current and signals. Furthermore, the connecting electrodes and pads are compatible with a variety of connection methods, enhancing design and manufacturing flexibility.

[0013] Optionally, the display module further includes a package, which is disposed on the mounting surface and encapsulates the light-emitting element and the first connector; the surface of the package away from the display surface is provided with a plurality of first epitaxial holes at intervals, the number of first epitaxial holes being the same as the number of first connectors, and the plurality of first connectors being located one-to-one in the plurality of first epitaxial holes.

[0014] The encapsulation component encapsulates the light-emitting element and the first connector and is mounted on the mounting surface, providing mechanical protection for them and isolating them from external dust, moisture, and impurities, thus reducing performance degradation caused by environmental factors. Simultaneously, the encapsulation structure buffers external impacts, reducing the risk of the light-emitting element and the first connector detaching or being damaged. Through the encapsulation process, the encapsulation component forms an integrated structure with the light-emitting element and the first connector, restricting the displacement of the light-emitting element and preventing it from shifting due to thermal expansion and contraction, vibration, etc., during long-term use. This enhances the stability of the light-emitting element mounted on the fireproof transparent component and the first connector mounted on the light-emitting element. Furthermore, the first connector is located within the first extended hole, and the hole wall of the first extended hole provides radial constraint to the first connector, preventing bending or deformation and ensuring its alignment accuracy with the second connector.

[0015] Optionally, a filler is provided on the surface of the control component near the light-emitting component, and the filler wraps the second connector; the surface of the filler near the light-emitting component is provided with a plurality of second epitaxial holes, the number of second epitaxial holes being the same as the number of second connectors, and the plurality of second connectors being located in the plurality of second epitaxial holes respectively.

[0016] The filler material surrounding the second connector not only fills the gaps between adjacent second connectors, enhancing the stability of the second connector when installed on the control component, but also forms a protective layer. This layer effectively isolates the second connector from external dust, moisture, or corrosive gases, absorbing vibrations and impacts experienced by the display module during transportation, installation, or use. It prevents the second connector from bending, deforming, or detaching due to external collisions, thus extending its service life.

[0017] Optionally, the filler is a dark ink or a dark filler adhesive; and / or, the surface of the filler near the light-emitting element is flush with the surface of the second connector near the light-emitting element and contacts the surface of the encapsulation away from the display surface.

[0018] Dark-colored materials have a strong ability to absorb light. On the one hand, they can effectively absorb ambient light and stray light from inside the display module, reducing the whitening or glare interference caused by these lights reflecting onto the display surface, thereby improving the display contrast of the display module. On the other hand, the dark appearance of the filler can also cover the control components, preventing the exposure of complex structures and affecting visual cleanliness, thus improving the aesthetics of the display module.

[0019] The surface of the filler near the light-emitting element is flush with the surface of the second connector near the light-emitting element, forming a flat mating surface. This mating surface makes tight contact with the surface of the package component away from the display surface. This structural design minimizes gaps between the filler and the package component. This surface contact not only allows the package component, filler, and second connector to form a stable integrated structure, effectively limiting the relative displacement of components when the display module is subjected to vibration or impact, but also ensures stable relative positions between components. Simultaneously, the flat surface contact evenly distributes contact stress across the entire mating surface, thereby extending the lifespan of the display module.

[0020] Optionally, the light-emitting element includes multiple spaced light-emitting bodies; multiple mounting grooves are provided on the mounting surface, the number of mounting grooves being the same as the number of light-emitting bodies, and partial structures of the multiple light-emitting bodies are embedded into the multiple mounting grooves in a one-to-one correspondence; and / or, an optical adjustment element is provided on the display surface, the optical adjustment element covering the light-emitting element, for the purpose of preventing ultraviolet rays and / or reducing reflected light and / or improving light transmittance.

[0021] The mounting groove not only secures the light-emitting element but also provides a mounting reference, improving the assembly efficiency of the light-emitting component and the fireproof transparent component.

[0022] Optical adjustment components that reduce reflected light and / or increase light transmittance can improve the display effect of the display module and enhance the visual experience. Optical adjustment components that can protect against ultraviolet rays can extend the lifespan of the display module and enhance its environmental adaptability.

[0023] According to another aspect of this application, a method for manufacturing a display module is provided, comprising: providing a fireproof transparent component and a control component, the fireproof transparent component having a display surface and a mounting surface disposed opposite to each other; transferring a light-emitting component in bulk to the mounting surface; and pressing and bonding the light-emitting component and the control component together to make the light-emitting component and the control component electrically connected.

[0024] On the one hand, the display module manufactured using the above-mentioned method has high structural strength, effectively preventing the fire-resistant transparent component from falling off during high-temperature combustion and thus losing its fire-retardant effect. On the other hand, using mass transfer technology to transfer the light-emitting component to the mounting surface of the fire-resistant transparent component allows for the precise transfer of a large number of tiny light-emitting chips (i.e., light emitters) in one go. Compared to the traditional method of mounting one chip at a time, this greatly shortens assembly time and improves the production efficiency of the display module. Furthermore, pressing and bonding the fire-resistant transparent component with the light-emitting component to the control component ensures tight contact between them, achieving a stable electrical connection and reducing the risk of display abnormalities due to poor contact, thereby improving the stability and reliability of the display module's operation.

[0025] According to another aspect of this application, a display device is provided, including the display module described above.

[0026] The fireproof transparent component provides direct fire protection for the light-emitting and control components, reducing the risk of the display module burning due to external fire sources or high temperatures. At the same time, since the light-emitting component is directly mounted on the mounting surface of the fireproof transparent component, this structural design ensures that the light emitted by the light-emitting component can be directly transmitted from the mounting surface to the display surface, which helps to reduce the optical path loss at the medium interface during light transmission. This not only helps to enhance the display effect of the display module, but also reduces the power consumption of the display module to a certain extent.

[0027] The beneficial effects of the display module provided in this application are as follows: the fireproof transparent component can directly provide fire protection for the light-emitting component and the control component, reducing the risk of the display module burning due to external fire sources or high temperatures; at the same time, since the light-emitting component is directly mounted on the mounting surface of the fireproof transparent component, this structural design can ensure that the light emitted by the light-emitting component can be directly transmitted from one side of the mounting surface to one side of the display surface, which helps to reduce the optical path loss at the medium interface during the light transmission process. This not only helps to enhance the display effect of the display module, but also reduces the power consumption of the display module to a certain extent.

[0028] Furthermore, the fire-resistant transparent component protects the light-emitting and control components, reducing the risk of scratches or damage, and eliminates the need for additional protective covers, thereby reducing the number of components in the display module and lowering costs. Additionally, the control component serves to support and mount the light-emitting and fire-resistant transparent components. Attached Figure Description

[0031] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0032] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly or indirectly on that other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to that other element. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application 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. Therefore, they should not be construed as limitations on this application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0035] As described in the background section, in related technologies, display modules, as the core components of display devices, can effectively display images or text. However, their design usually focuses more on optimizing display performance (such as resolution, brightness, response speed, etc.) and relatively neglects fire resistance performance.

[0036] Reference Figures 1 to 4To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides a display module, which includes a fireproof transparent component 100, a light-emitting component 200, and a control component 300. The fireproof transparent component 100 has a display surface 110 and a mounting surface 120 disposed opposite to each other; the light-emitting component 200 is disposed on the mounting surface 120; the control component 300 is located on the side of the light-emitting component 200 away from the display surface 110 and is electrically connected to the light-emitting component 200; the light-emitting component 200 is mounted on the control component 300.

[0037] In this embodiment, the display module is an LED module, where LED stands for Light Emitting Diode. It is understood that the display module can also be an OLED display module, where OLED stands for Organic Light-Emitting Diode Module. The fire-resistant transparent component 100 can be fire-resistant glass, fire-resistant transparent plastic, fire-resistant transparent ceramic, or a composite fire-resistant transparent film. The light-emitting component 200 is completely disposed on the mounting surface 120, meaning the mounting surface 120 of the fire-resistant transparent component 100 completely covers the light-emitting component 200. The display surface 110 and the mounting surface 120 are arranged opposite each other along the thickness direction of the fire-resistant transparent component 100. When the user observes the display module, the display surface 110 is the front side to be observed, and the mounting surface 120 is the back side to be observed. The light-emitting component 200 is fixedly mounted on the mounting surface 120. The control component 300 is a PCB. The full English name of PCB is Printed Circuit Board. Specifically, the control component 300 is a PCB with FR-4 and copper wire as its core. The full English name of FR is Flame Retardant. The Chinese name is flame retardant. 4 refers to the grade number of this type of material.

[0038] The fireproof transparent component 100 provides direct fire protection for the light-emitting component 200 and the control component 300, reducing the risk of the display module burning due to external fire sources or high temperatures. At the same time, since the light-emitting component 200 is directly mounted on the mounting surface 120 of the fireproof transparent component 100, this structural design ensures that the light emitted by the light-emitting component 200 can be directly transmitted from the mounting surface 120 side to the display surface 110 side, which helps to reduce the optical path loss at the medium interface during light transmission. This not only helps to enhance the display effect of the display module, but also reduces the power consumption of the display module to a certain extent.

[0039] Furthermore, the fireproof transparent component 100 protects the light-emitting component 200 and the control component 300, reducing the risk of scratches or damage, and eliminates the need for additional protective covers, thereby reducing the number of components in the display module and lowering costs. Additionally, the control component 300 serves to support and mount the light-emitting component 200 and the fireproof transparent component 100.

[0040] In addition, the fireproof transparent component 100 is made of UTG glass. UTG stands for Ultra Thin Glass.

[0041] The fire-resistant transparent component 100 made of UTG glass has several advantages: First, high hardness: Although UTG glass has a certain degree of flexibility, it still maintains the inherent high hardness of glass materials. Its Mohs hardness is usually between 6 and 7. Compared with the traditional plastic fire-resistant transparent component 100, UTG glass is more resistant to scratches and wear.

[0042] Secondly, extreme thinness: The thickness of UTG glass is usually between 0.1mm and 0.3mm, and can even be thinner. This characteristic allows the display module equipped with UTG glass to be significantly reduced in overall weight and thickness, greatly improving the portability and exquisite appearance of the product.

[0043] Thirdly, excellent optical performance: UTG glass has excellent light transmittance, generally exceeding 90%. High light transmittance ensures the vividness of colors and the clarity of images displayed on the screen. At the same time, it also has good optical uniformity, with consistent display effects in all areas of the screen, without obvious color differences or brightness variations.

[0044] Fourth, UTG glass is chemically stable, maintaining its structure and performance even when exposed to common acids, alkalis, sweat, and oil. This characteristic ensures the reliability of UTG glass in complex operating environments.

[0045] Reference Figures 1 to 6 In one embodiment, the display module further includes a first connector 400 and a second connector 500 electrically connected to each other. The first connector 400 is disposed on the light-emitting element 200 and electrically connected to the light-emitting element 200; the second connector 500 is disposed on the control element 300 and electrically connected to the control element 300.

[0046] In this embodiment, the first connector 400 and the second connector 500 may be a needle socket and a needle plug, a male connector and a female connector, or a conductive spring and a conductive contact.

[0047] The first connector 400 and the second connector 500, used in conjunction, not only establish an electrical connection channel between the light-emitting component 200 and the control component 300, acting as a connecting bridge, but also, when an electrical connection fault occurs in the display module, the source of the fault can be quickly located by individually testing the first connector 400 and the second connector 500, simplifying the troubleshooting process and improving maintenance efficiency and convenience. Furthermore, the first connector 400 and the second connector 500 can be equipped with different types of mating components according to the actual needs of the display module, broadening the design flexibility and scenario adaptability of the display module.

[0048] Reference Figures 1 to 7 In one embodiment, the light-emitting element 200 includes a plurality of spaced-apart light-emitting bodies 210; the first connector 400 includes a plurality of first connectors 410, the number of first connectors 410 being twice the number of light-emitting bodies 210, and two first connectors 410 electrically connected to the light-emitting bodies 210 are spaced apart on the surface of the light-emitting body 210 away from the display surface 110; the second connector 500 includes a plurality of second connectors 510, the number of second connectors 510 being twice the number of light-emitting bodies 210, and the plurality of second connectors 510 are spaced apart on the surface of the control element 300 near the light-emitting element 200, and are electrically connected to the plurality of first connectors 410 in a one-to-one correspondence.

[0049] In this embodiment, the light emitter 210 is any one of the RGB chips, where R represents Red, G represents Green, and B represents Blue. The red light chip is made of aluminum indium gallium phosphide (AIGaphos), while the blue and green light chips are made of gallium nitride (GaN) or indium gallium phosphide (IGGaS). Multiple light emitters 210 are arranged in a rectangular pattern on the mounting surface 120. Each light emitter 210 has two first connectors 410, and these two first connectors 410 are electrically connected to the light emitter 210 that carries them. Furthermore, the two first connectors 410 on the same light emitter 210 are respectively formed as positive and negative electrodes. Two adjacent second connectors 510, corresponding to the two first connectors 410 on the same light emitter 210, are respectively formed as positive and negative electrodes.

[0050] On the one hand, each light-emitting element 210 is equipped with two first connectors 410, and the two first connectors 410 are electrically connected to two corresponding second connectors 510. This structural design allows the current to be introduced to the light-emitting element 210 more evenly, reducing current concentration caused by single-point connection, thereby reducing the risk of local overheating or brightness decay of the light-emitting element 210. At the same time, stable current transmission can reduce the brightness and color temperature deviation between different light-emitting elements 210, thereby effectively improving the uniformity of the display module image.

[0051] On the other hand, each light-emitting element 210 is independently powered and transmits electrical signals through two corresponding first connectors 410 and two second connectors 510, and the working circuits of each light-emitting element 210 do not interfere with each other. When a single light-emitting element 210 fails, the remaining light-emitting elements 210 can still operate normally, maximizing the overall luminous effect and display function of the display module; and during maintenance, it is not necessary to replace the entire light-emitting component 200, but only to replace the faulty light-emitting element 210, first connector 410 or second connector 510, thereby reducing maintenance difficulty and cost.

[0052] On the other hand, when the light emitter 210 malfunctions, the source of the fault can be quickly determined by detecting the on / off status of its two corresponding first connectors 410: if both first connectors 410 are disconnected, the light emitter 210 itself may be faulty; if only a single first connector 410 is disconnected, only the faulty first connector 410 needs to be replaced, without replacing the entire light emitter 210 or control component 300, thereby shortening maintenance time and reducing costs.

[0053] Reference Figure 2 as well as Figures 5 to 7 In one embodiment, one of the first connector 410 and the second connector 510 is provided with a connecting structure 420, and the first connector 410 and the second connector 510 are kept in contact with the connecting structure 420 and electrically connected.

[0054] In this embodiment, the connecting structure 420 is a tin connecting piece disposed on the surface of the first connector 410 away from the light-emitting element 210, and the tin connecting piece is made by melting tin balls; the surface of the first connector 410 away from the light-emitting element 210 is kept in contact with the connecting structure 420, and the surface of the second connector 510 close to the light-emitting element 210 is kept in contact with the connecting structure 420.

[0055] The connecting structure 420 is a tin connecting piece. This structural design not only ensures that the first connector 410 and the second connector 510 form a reliable and low-resistance conductive path, but also that the molten tin ball automatically fills the connection gap and achieves precise alignment due to surface tension, which can accommodate a certain degree of assembly deviation and reduce the requirements for assembly accuracy. In addition, the liquid tin can coat the tiny oxide layer on the surface of the first connector 410 and the second connector 510, ensuring the continuity of the conductive path and reducing the problem of poor contact caused by oxidation.

[0056] In addition, other metallic materials (such as copper, silver or bismuth) may be incorporated into the connecting structure 420 to adjust its melting point, strength and conductivity.

[0057] It is understood that the connection structure 420 may also be disposed on the surface of the second connector 510 near the light source 210, and the connection structure 420 may also be conductive adhesive, silver paste, metal spring, metal probe, conductive foam or solder paste.

[0058] The connection structure 420 not only enables the first connector 410 and the second connector 510 to be connected, but also ensures that both the first connector 410 and the second connector 510 are firmly abutted against the connection structure 420. This structural design has multiple advantages: Firstly, this structure allows the first connector 410 and the second connector 510 to apply continuous pressure to the connecting structure 420, ensuring that the contact surfaces of the three are tightly fitted, effectively eliminating minute gaps, thereby reducing contact resistance and reducing signal attenuation during current transmission.

[0059] Secondly, the static pressure generated in the tight state can prevent the connection between the first connector 410, the second connector 510 and the connection structure 420 from loosening or separating due to vibration or impact, thereby improving the stability and reliability of the connection.

[0060] Reference Figures 5 to 7 In one embodiment, one of the first connector 410 and the second connector 510 is a connecting electrode, and the other is a connecting pad.

[0061] In this embodiment, the first connector 410 is a connecting electrode, and the second connector 510 is a connecting pad. Specifically, the connecting electrode uses gold and silver as core materials, and balances conductivity, reliability, and cost through a single-layer or multi-layer composite structure (such as gold / nickel / copper, silver / nickel). The connecting pad uses copper as a substrate, and optimizes welding and oxidation resistance through surface plating (such as nickel-gold, silver, sintered silver, etc.), achieving a balance between thermal conductivity and reliability in synergy with the substrate. It can be understood that the first connector 410 can also be a connecting pad, and the second connector 510 can be a connecting electrode.

[0062] The matching connecting electrodes and pads not only enable automatic positioning and reduce assembly errors, but also allow the protruding shape of the connecting electrodes to form a tight contact with the connecting pads, thereby increasing the effective conductive area, reducing contact resistance, and ensuring stable transmission of current and signals. Furthermore, the connecting electrodes and pads are compatible with a variety of connection methods, enhancing design and manufacturing flexibility.

[0063] The light emitter 210 is typically small in size and light in weight. The first connector 410 associated with it is designed as a connecting electrode, eliminating the need for an additional heavy structure and helping to maintain the lightweight characteristics of the light emitter 210. The control component 300 has enough space to support the connecting pads. The combination of the two can avoid the risk of the light emitter 210 falling off due to the excessive weight of the connecting components.

[0064] Reference Figure 1 , Figure 2 , Figure 4 , Figure 7 as well as Figure 8 In one embodiment, the display module further includes a package 600, which is disposed on the mounting surface 120 and encapsulates the light-emitting element 200 and the first connector 400. The surface of the package 600 away from the display surface 110 is provided with a plurality of first extension holes 610 at intervals. The number of first extension holes 610 is the same as the number of first connectors 410, and the plurality of first connectors 410 are respectively located in the plurality of first extension holes 610.

[0065] In this embodiment, the encapsulation 600 is fixedly installed on the mounting surface 120 and completely encapsulates the light-emitting element 200 and the first connector 400. That is, the light-emitting element 200 and the first connector 400 are completely wrapped by the encapsulation 600, and the first connector 400 makes contact with the second connector 510 through the first extension hole 610.

[0066] The encapsulation component 600 is made of flame-retardant epoxy resin, bisphenol A epoxy resin, or silicone-modified epoxy resin. Specifically, when the encapsulation component 600 is made of flame-retardant epoxy resin, its inherent flame-retardant properties and structural strength can enhance the mechanical strength of the light-emitting component 200 and the first connector 400 while providing fire protection, reducing damage to the light-emitting component 200 and the first connector 400 caused by external impacts and vibrations. When the encapsulation component 600 is made of bisphenol A epoxy resin, its molecular structure has good transparency, which can effectively reduce the absorption and scattering of light from the light-emitting component 200, thereby improving the light transmittance of the light-emitting component 200 and ensuring display brightness. When the encapsulation component 600 is made of silicone-modified epoxy resin, the silicone component can improve the material's weather resistance and UV aging resistance, delaying the yellowing phenomenon caused by light and high temperature during long-term use of the encapsulation component 600, thereby improving the yellowing resistance of the light-emitting component 200 and the first connector 400 and maintaining the stability of the long-term display effect.

[0067] Furthermore, the surface of the first connector 410 away from the mounting surface 120 is flush with the surface of the package 600 away from the mounting surface. The shape and size of the profile of the package 600 projected onto the mounting surface 120 are the same as the shape and size of the profile of the mounting surface 120; however, it is understood that the shape and size of the profile of the package 600 projected onto the mounting surface 120 may also be different from the shape and size of the profile of the mounting surface 120. The first connector 410 maintains close contact with the wall of the first extension hole 610.

[0068] The encapsulation component 600 encapsulates the light-emitting component 200 and the first connector 400 and is disposed on the mounting surface 120. It can provide mechanical protection for the light-emitting component 200 and the first connector 400, isolate them from external dust, moisture and impurities, and reduce the performance degradation of the light-emitting component 200 and the first connector 400 caused by environmental factors. At the same time, the encapsulation structure can buffer external impacts and reduce the risk of the light-emitting component 200 and the first connector 400 falling off or being damaged.

[0069] The encapsulation component 600 is integrated with the light-emitting component 200 and the first connector 410 through the encapsulation process. This can limit the displacement of the light-emitting component 200 and prevent it from shifting due to thermal expansion and contraction, vibration, etc. during long-term use. This enhances the stability of the light-emitting component 200 installed on the fireproof transparent component 100 and the first connector 410 installed on the light-emitting component 210. At the same time, the first connector 410 is located in the first extension hole 610. The hole wall of the first extension hole 610 can form a radial constraint on the first connector 410, preventing the first connector 410 from bending or deforming and ensuring its alignment accuracy with the second connector 510.

[0070] Reference Figure 1 , Figure 2 , Figure 7 as well as Figure 9 In one embodiment, a filler 700 is provided on the surface of the control member 300 near the light-emitting member 200, and the filler 700 encloses the second connector 500; a plurality of second extension holes 710 are provided on the surface of the filler 700 near the light-emitting member 200, the number of second extension holes 710 is the same as the number of second connectors 510, and the plurality of second connectors 510 are respectively located in the plurality of second extension holes 710.

[0071] In this embodiment, the surface of the control member 300 where the second connector 500 is located is the bearing surface 310. The filler 700 is disposed on the bearing surface 310, and the filler 700 completely encloses the second connector 500, that is, the second connector 500 is completely enclosed by the filler 700. It can be understood that the filler 700 may also only enclose a portion of the structure of the second connector 500, that is, a portion of the structure of the second connector 500 is located outside the filler 700. The second connector 510 maintains close contact with the wall of the second extension hole 710.

[0072] The filler 700 surrounds the second connector 500, not only filling the gap between adjacent second connectors 510 and enhancing the stability of the second connector 500 when installed on the control component 300, but also forming a protective layer. This layer effectively isolates the second connector 500 from external dust, moisture, or corrosive gases, absorbing vibrations and impacts experienced by the display module during transportation, installation, or use. This prevents the second connector 510 from bending, deforming, or detaching due to external impacts, thus extending the service life of the second connector 500.

[0073] Furthermore, the shape and size of the profile of the filler 700 projected onto the bearing surface 310 are the same as the shape and size of the bearing surface 310; it is understood that the shape and size of the profile of the filler 700 projected onto the bearing surface 310 may also be different from the shape and size of the bearing surface 310.

[0074] Reference Figure 1 , Figure 2 , Figure 7 as well as Figure 9 In one embodiment, the filler 700 is a dark ink or a dark filler adhesive. In this embodiment, the filler 700 is black ink; it is understood that the filler 700 may also be other dark inks, dark or black filler adhesives.

[0075] Dark-colored materials have a strong ability to absorb light. On the one hand, they can effectively absorb ambient light and stray light from inside the display module, reducing the whitening or glare interference caused by these lights reflecting onto the display surface 110, thereby improving the display contrast of the display module. On the other hand, the dark appearance of the filler 700 can also cover the control component 300, preventing the complex structure from being exposed and affecting visual cleanliness, thereby improving the aesthetics of the display module.

[0076] Reference Figure 1 and Figure 2 In one embodiment, the surface of the filler 700 near the light-emitting element 200 is flush with the surface of the second connector 510 near the light-emitting element 210, and contacts the surface of the encapsulation 600 away from the display surface 110.

[0077] In this embodiment, the surface of the filler 700 near the light-emitting element 200 is in contact with the surface of the encapsulation 600 away from the display surface 110. It can be understood that the surface of the filler 700 near the light-emitting element 200 may also be located on the side of the second connector 510 near the light-emitting element 200 away from the light-emitting element 200.

[0078] The surface of the filler 700 near the light-emitting element 200 is flush with the surface of the second connector 510 near the light-emitting element 210, forming a flat mating surface. This mating surface makes tight contact with the surface of the encapsulation 600 away from the display surface 110. This structural design minimizes gaps between the filler 700 and the encapsulation 600. This surface contact not only allows the encapsulation 600, the filler 700, and the second connector 500 to form a stable integrated structure, effectively limiting the relative displacement of components when the display module is subjected to vibration or impact, ensuring the stability of the relative positions between components, but also ensures that the flat surface contact evenly distributes contact stress across the entire mating surface, thereby extending the service life of the display module.

[0079] Reference Figure 3 and Figure 4 In one embodiment, the light-emitting element 200 includes a plurality of light-emitting bodies 210 spaced apart; a plurality of mounting grooves 130 are provided on the mounting surface 120, the number of mounting grooves 130 being the same as the number of light-emitting bodies 210, and a portion of the structure of the plurality of light-emitting bodies 210 is embedded into the plurality of mounting grooves 130 in a one-to-one correspondence.

[0080] In this embodiment, the inner diameter of the mounting groove 130 is 1 to 3 μm larger than the outer diameter of the light-emitting element 210. The mounting groove 130 not only fixes the light-emitting element 210, but also provides a mounting reference for the light-emitting element 210, thereby improving the assembly efficiency of the light-emitting element 200 and the fireproof transparent element 100.

[0081] Reference Figure 4 and Figure 10 In one embodiment, an optical adjustment element 800 is provided on the display surface 110, which covers the light-emitting element 200 for the purpose of preventing ultraviolet rays and / or reducing reflected light and / or improving light transmittance.

[0082] In this embodiment, the optical adjustment element 800 is a PET UV protection film, an OCA film, or a functional coating (such as a coating containing nano-titanium dioxide, zinc oxide, etc.).

[0083] PET UV-protective films, OCA films, and functional coatings are all used for UV protection. Specifically: PET stands for Polyethylene Terephthalate. PET UV-protective film is made from environmentally friendly UV-protective functional masterbatch, and is colorless and transparent with a high UV blocking rate.

[0084] OCA stands for Optically Clear Adhesive. OCA film is a special optically transparent adhesive film that, in addition to having high light transmittance and high adhesion, also has the ability to resist ultraviolet rays.

[0085] UV stands for Ultraviolet. The functional coating can contain nano-titanium dioxide, zinc oxide, and other components. This functional coating can be directly applied to the display surface 110 of the fireproof transparent component 100. The nanomaterials in the functional coating not only absorb and scatter ultraviolet rays, providing UV protection, but also enhance light transmittance by optimizing the coating's refractive index and microstructure, thereby improving the transmittance and optical performance of the fireproof transparent component 100.

[0086] It is understood that the optical adjustment component 800 may also include at least two components selected from PET UV protection film, OCA film or other functional coatings, and the two components are stacked.

[0087] Optical adjustment components 800, which can reduce reflected light and / or increase light transmittance, can improve the display effect of the display module and enhance the visual experience. Optical adjustment components 800 that provide UV protection can extend the lifespan of the display module and enhance its environmental adaptability.

[0088] Reference Figures 1 to 11 According to another aspect of this application, embodiments of this application also provide a method for manufacturing a display module, the method comprising: Step S100: Provide a fireproof transparent component 100 and a control component 300. The fireproof transparent component 100 has a display surface 110 and a mounting surface 120 that are disposed opposite to each other.

[0089] The fire-resistant transparent component 100 can be fire-resistant glass, fire-resistant transparent plastic, fire-resistant transparent ceramic, or composite fire-resistant transparent film. The display surface 110 and the mounting surface 120 are arranged opposite each other along the thickness direction of the fire-resistant transparent component 100. When the user observes the display module, the display surface 110 is the front to be observed, and the mounting surface 120 is the back to be observed. The control component 300 is a PCB; specifically, the control component 300 is a PCB with FR-4 and copper wire as its core.

[0090] Step S200: Transfer the light-emitting element 200 in large quantities to the mounting surface 120.

[0091] In this embodiment, a growth substrate on which light-emitting elements 200 are grown is first provided, and then the light-emitting elements 200 are transferred in large quantities from the growth substrate to the mounting surface 120.

[0092] The light-emitting element 200 is a wafer-level light-emitting chip array, and includes multiple spaced light-emitting bodies 210. The light-emitting chip is the light-emitting body 210. The early manufacturing process of the light-emitting element is as follows: a light-emitting epitaxial layer (such as GaN-based material) is formed on a semiconductor substrate (such as sapphire) through an epitaxial growth process, and then multiple spaced light-emitting chips are formed on a single wafer through pattern photolithography, etching and electrode preparation.

[0093] To ensure the stability of the light-emitting element 200 mounted on the fireproof transparent element 100, multiple mounting grooves 130 are etched on the mounting surface 120. The number of mounting grooves 130 is the same as the number of light-emitting elements 210. Parts of the structure of the multiple light-emitting elements 210 are respectively embedded into the multiple mounting grooves 130. Specifically, the groove depth of the mounting groove 130 is 5 to 15 μm, and the inner diameter of the mounting groove 130 is 1 to 3 μm larger than the outer diameter of the light-emitting element 210.

[0094] The light-emitting element 200 is transferred into the mounting groove 130 by laser mass transfer. Mass transfer refers to the batch assembly process of quickly and accurately transferring a large number of tiny light-emitting chips (i.e., light-emitting bodies 210) from their original growth substrate (such as sapphire substrate or temporary carrier) to a preset position on the target substrate. Laser mass transfer refers to the batch assembly process of accurately transporting a large number of micron-sized light-emitting chips from the original substrate to a designated position on the target substrate in one go by means of laser energy.

[0095] In addition, since the fireproof transparent component 100 made of UTG glass has a certain degree of flexibility, when transferring the light-emitting component 200 in large quantities, the display surface 110 of the fireproof transparent component 100 is vacuum adsorbed to ensure the stability and flatness of the fireproof transparent component 100.

[0096] Step S300: Press-bond the light-emitting element 200 and the control element 300 together to make the light-emitting element 200 and the control element 300 electrically connected.

[0097] A first connector 400 is disposed on the surface of the light-emitting element 200 away from the display surface 110. There are multiple first connectors 400, and the number of first connectors 410 is twice that of the light-emitting element 210. Two first connectors 410 electrically connected to the light-emitting element 210 are disposed at intervals on the surface of the light-emitting element 210 away from the display surface 110. Each first connector 410 serves as a connecting electrode. Specifically, the first connector 410 is formed through a process of "metal material deposition → photolithography pattern definition → etching": first, a metal thin film is deposited on the light-emitting element 210; then, an electrode pattern is defined on the surface of the metal layer using photolithography; finally, excess metal not protected by photoresist is removed by etching to form the required connecting electrode.

[0098] A second connector 500 is provided on the surface of the control component 300 near the light-emitting component 200. The second connector 500 includes a plurality of second connectors 510 spaced apart. The number of second connectors 510 is the same as the number of first connectors 410. The second connectors 510 are connection pads. The plurality of second connectors 510 are electrically connected to the plurality of first connectors 410 in a one-to-one correspondence.

[0099] Furthermore, a connection structure 420, which is a solder ball, is prepared on the surface of the first connector 410 away from the light emitter 210. This connection structure 420 not only ensures that the first connector 410 and the second connector 510 form a reliable and low-resistance conductive path, but also allows the solder ball to automatically fill the connection gap and achieve precise alignment due to surface tension after melting, which can accommodate a certain degree of assembly deviation and reduce the requirements for assembly accuracy. In addition, the liquid solder can coat the tiny oxide layer on the surface of the first connector 410 and the second connector 510, ensuring the continuity of the conductive path and reducing the problem of poor contact caused by oxidation.

[0100] Finally, the first connector 410 with the connecting structure 420 is flipped onto the preheated second connector 510 through hot pressing or reflow soldering process to realize the electrical connection between the light-emitting element 200 and the control element 300, thereby completing the preparation of the display module.

[0101] On the one hand, the display module made by the above preparation method has high structural strength and can effectively prevent the fireproof transparent part 100 from falling off during high-temperature combustion and losing its fireproof and flame-retardant effect.

[0102] On the other hand, by using mass transfer technology to transfer the light-emitting component 200 to the mounting surface 120 of the fireproof transparent component 100, a large number of tiny light-emitting chips (i.e., light-emitting bodies 210) can be accurately transferred at one time. Compared with the traditional method of mounting one by one, this can greatly shorten the assembly time and improve the production efficiency of the display module.

[0103] On the other hand, by pressing and bonding the fireproof transparent part 100 with the light-emitting element 200 to the control element 300, the light-emitting element 200 and the control element 300 can form a tight contact, realize a stable electrical connection between the light-emitting element 200 and the control element 300, reduce the risk of display abnormalities due to poor contact, and improve the stability and reliability of the display module operation.

[0104] Reference Figures 1 to 11 In one embodiment, after the first connector 400 is prepared, an encapsulation 600 is filled on the mounting surface 120 of the fireproof transparent component 100, and the encapsulation 600 encapsulates the light-emitting component 200 and the first connector 400.

[0105] In this embodiment, the surface of the encapsulation 600 away from the display surface 110 is provided with a plurality of first extension holes 610 at intervals. The number of first extension holes 610 is the same as the number of first connectors 410, and the plurality of first connectors 410 are respectively located in the plurality of first extension holes 610. The first connectors 410 are in close contact with the hole walls of the first extension holes 610. The encapsulation 600 is fixedly mounted on the mounting surface 120 and completely encapsulates the light-emitting element 200 and the first connectors 400, that is, the light-emitting element 200 and the first connectors 400 are completely wrapped by the encapsulation 600, and the first connectors 400 make contact with the second connectors 510 through the first extension holes 610.

[0106] Furthermore, the surface of the first connector 410 away from the mounting surface 120 is flush with the surface of the package 600 away from the mounting surface. The shape and size of the profile of the package 600 projected onto the mounting surface 120 are the same as the shape and size of the profile of the mounting surface 120. It is understood that the shape and size of the profile of the package 600 projected onto the mounting surface 120 may also be different from the shape and size of the profile of the mounting surface 120.

[0107] Reference Figures 1 to 11 In one embodiment, after the second connector 500 is prepared, a filler 700 is filled on the surface of the control member 300 on which the second connector 500 is provided, and the filler 700 covers the second connector 500.

[0108] In this embodiment, a plurality of second epitaxial holes 710 are provided on the surface of the filler 700 near the light-emitting element 200. The number of second epitaxial holes 710 is the same as the number of second connectors 510. The plurality of second connectors 510 are respectively located in the plurality of second epitaxial holes 710. The second connectors 510 are in close contact with the hole walls of the second epitaxial holes 710.

[0109] The surface of the control component 300 where the second connector 500 is located is a bearing surface 310. The filler 700 is disposed on the bearing surface 310, and the filler 700 completely encloses the second connector 500, that is, the second connector 500 is completely enclosed by the filler 700. It can be understood that the filler 700 may also only enclose a part of the structure of the second connector 500, that is, a part of the structure of the second connector 500 is located outside the filler 700.

[0110] Furthermore, the shape and size of the profile of the filler 700 projected onto the bearing surface 310 are the same as the shape and size of the bearing surface 310; it is understood that the shape and size of the profile of the filler 700 projected onto the bearing surface 310 may also be different from the shape and size of the bearing surface 310.

[0111] Reference Figures 1 to 11An optical adjustment element 800 is prepared on the display surface 110 of the fireproof transparent element 100.

[0112] In this embodiment, the optical adjustment element 800 is a PET UV protection film, an OCA film, or other functional coatings (such as coatings containing nano-titanium dioxide, zinc oxide, etc.).

[0113] When the optical adjustment element 800 is an anti-ultraviolet coating, the preparation process of the optical adjustment element 800 is as follows: first, an anti-ultraviolet coating is applied to the display surface 110 of the fireproof transparent element 100 by dry or wet method, and then protected with a release film; after the light emitter 210 and the control element 300 are electrically connected, the release film is finally removed.

[0114] Reference Figures 1 to 10 According to another aspect of this application, embodiments of this application also provide a display device, which includes the display module described above.

[0115] In this embodiment, the display module is an LED display module; however, it can also be an OLED display module. The display device further includes a display frame, on which the display module is mounted.

[0116] The fireproof transparent component 100 provides direct fire protection for the light-emitting component 200 and the control component 300, reducing the risk of the display module burning due to external fire sources or high temperatures. At the same time, since the light-emitting component 200 is directly mounted on the mounting surface 120 of the fireproof transparent component 100, this structural design ensures that the light emitted by the light-emitting component 200 can be directly transmitted from the mounting surface 120 side to the display surface 110 side, which helps to reduce the optical path loss at the medium interface during light transmission. This not only helps to enhance the display effect of the display module, but also reduces the power consumption of the display module to a certain extent.

[0117] In summary, the display module and its manufacturing method and display device provided in this embodiment have at least the following beneficial technical effects: the fireproof transparent component 100 can directly provide fire protection for the light-emitting component 200 and the control component 300, reducing the risk of the display module burning due to external fire sources or high temperatures; at the same time, since the light-emitting component 200 is directly mounted on the mounting surface 120 of the fireproof transparent component 100, this structural design can ensure that the light emitted by the light-emitting component 200 can be directly transmitted from the mounting surface 120 side to the display surface 110 side, which helps to reduce the optical path loss at the medium interface during the light transmission process, thereby not only helping to enhance the display effect of the display module, but also reducing the power consumption of the display module to a certain extent.

[0118] Furthermore, the fireproof transparent component 100 protects the light-emitting component 200 and the control component 300, reducing the risk of scratches or damage, and eliminates the need for additional protective covers, thereby reducing the number of components in the display module and lowering costs. Additionally, the control component 300 serves to support and mount the light-emitting component 200 and the fireproof transparent component 100.
