[0002] Currently, mobile phones and other display terminal devices are fixed to their display modules using a mid-frame and adhesive bonding process. As screen bezels become increasingly narrow, the adhesive bonding surface on the mid-frame also becomes narrower. However, to meet the actual fixing requirements, the adhesive surface between the display module and the mid-frame cannot be narrowed further, causing the adhesive to overflow. This overflowing adhesive easily adheres to the inner side of the mid-frame. During assembly, the adhesive overflowing onto the inner side of the mid-frame can interfere with the screen, causing top-screen issues and affecting the display module's display performance. Summary of the Invention

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are protected by this application.

[0049] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of one embodiment of the display device of this application. Figure 2 yes Figure 1 A cross-sectional structural diagram.

[0050] The display device includes a housing assembly 100 and a display panel 200. The housing assembly 100 consists of a base plate 101 and a side plate 102. Specifically, the base plate 101 has a first surface 1010; the side plate 102 is disposed around the periphery of the base plate 101 on the first surface 1010, and the side plate 102 and the base plate 101 cooperate to form an internal accommodating space 103.

[0051] In one application scenario, the base plate 101 and the side plate 102 can be a separate structure, and fixed together by a snap-fit ​​structure or an adhesive structure. In other application scenarios, in order to improve the structural sealing, the base plate 101 and the side plate 102 can also be a one-piece molded structure, which can achieve the effect of this embodiment.

[0052] The display panel 200 can be an OLED panel, LCD panel, Micro-LED panel, etc., all of which can achieve the effects of this embodiment. In this embodiment, the display panel 200 includes a glass substrate 201, a polarizer 202, a panel layer 203, and a buffer layer 204, which are sequentially glued together. The glass substrate 201 is covered on the accommodating space 103 and fixed to the side plate 102, sealing the accommodating space 103 to prevent the external environment from affecting the battery, motherboard, flexible circuit board, and other components installed in the accommodating space 103; the polarizer 202, panel layer 203, and buffer layer 204 are disposed within the accommodating space 103.

[0053] Specifically, the side plate 102 has a second surface 1020 located on the side closer to the accommodating space 103 and a third surface 1021 located on the side away from the bottom plate 101.

[0054] The third surface 1021 carries the adhesive 300, and the display panel 200 is fixed to the housing assembly 100 by carrying the cured adhesive 300 on the third surface 1021.

[0055] It is understood that in other embodiments, adhesive can also be applied to both sides of the third surface 1021, so that the display panel 200 is fixed to the housing assembly 100 by the adhesive on both sides of the third surface 1021, and the effect of this embodiment can be achieved.

[0056] In order to increase the load capacity of adhesive 300 on the third surface 1021, and at the same time improve the fixing stability and sealing of the display panel 200 and the side plate 102, an adhesive placement groove 1022 is provided on the third surface 1021. The adhesive placement groove 1022 extends along the extension direction of the side plate 102 and is arranged on the third surface 1021, and adhesive 300 is placed in the adhesive placement groove 1022.

[0057] The display panel 200 covers the accommodating space 103 and is fixedly attached to the adhesive 300 in the adhesive tray 1022.

[0058] In one application scenario, adhesive 300 can be a hot melt adhesive. Hot melt adhesives are plastic adhesives whose physical state changes with temperature within a certain temperature range, while their chemical properties remain unchanged. Compared to ordinary adhesives, hot melt adhesives have greater bonding strength and better curing effect. They are also easier to control in terms of consistency, better meeting the design requirements of narrow bezels in electronic devices. Furthermore, hot melt adhesives are thermoplastic polyurethanes, making products bonded with them easier to disassemble or repair. In other application scenarios, adhesive 300 can also be other colloids whose viscosity decreases upon heating, achieving the same effects as described in this embodiment.

[0059] In pursuit of better display quality, the bezel of the display panel 200 is becoming increasingly narrow, resulting in a gradual reduction in the fixing area between the third surface 1021 and the display panel 200. However, to ensure the fixing effect between the display panel 200 and the housing assembly 100, the amount of adhesive cannot be reduced. Therefore, after the display panel 200 is placed on the housing assembly 100 and bonded and pressurized, adhesive 300 overflows from the adhesive tray 1022 and easily accumulates on the second surface 1020 of the side panel 102. After the adhesive 300 accumulated on the second surface 1020 cures, it will interfere with the panel layer 203 of the display panel 200, causing problems such as screen misalignment and affecting the display effect.

[0060] To solve the above problems, a heating unit 400 is provided on the second surface 1020. The heating unit 400 heats the adhesive 300 overflowing from the third surface 1021, causing the adhesive 300 to flow to other locations or level on the third surface 1021, so as to prevent it from curing and accumulating on the third surface 1021.

[0061] It is understandable that the heated adhesive 300 can maintain its fluidity and flow along the second surface 1020. In one application scenario, the overflowing adhesive 300 flows onto the base plate 101 after passing through the second surface 1020. In other application scenarios, the overflowing adhesive 300 can also remain partially or completely on the second surface 1020 and spread evenly on the second surface 1020, thus achieving the effect of this embodiment.

[0062] In other embodiments, the heating unit 400 can also be located in other positions, as long as it can heat the second surface 1020 or directly heat the adhesive 300. For example, the heating unit 400 can be located outside the housing assembly 100 to heat the side plate 102 to heat the second surface 1020, or the heating unit 400 can be located inside the accommodating space 103 to directly heat the adhesive 300, or the heating unit 400 can directly heat the working environment so that the second surface 1020 and the adhesive 300 are heated. All of these can achieve the effect of this embodiment.

[0063] Specifically, please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of one embodiment of the housing assembly of this application. Figure 4 yes Figure 3 A cross-sectional structural schematic diagram. The heating unit 400 includes a heating element 401 that can be coupled to a power source (not shown in the figure) to generate heat. The heating element 401 is attached to the second surface 1020 and fixed to the side plate 102. The power source supplies power to the heating element 401 to control its heating.

[0064] In one application scenario, the power supply can be the display device's own battery, which is located within the accommodating space 103. The heating element 401 is controlled by connecting its power supply circuit to the battery. In other application scenarios, the power supply can be an external power supply dedicated to controlling the heating element 401. The external power supply is electrically connected to the heating element 401 via a connecting wire (not shown in the figure) passing through the base plate 101 to control its heating. The specific power supply configuration can be selected according to the display device. For example, in a display device with a rear fingerprint recognition module, when the rear fingerprint recognition module is not installed, a connecting wire can be set to electrically connect the heating element 401 and the external battery. After the heating element 401 finishes working, the connecting wire can be removed and the rear fingerprint recognition module can be installed.

[0065] In one application scenario, the heating element 401 can be a conductive metal sheet, such as a copper sheet or a resistor sheet. In other application scenarios, the heating element 401 can also be an energized coil, a graphene material plate, a semiconductor material plate, or other components that can generate heat through electricity.

[0066] To ensure that no adhesive 300 accumulates around the annular area of ​​the second surface 1020, heating elements 401 are arranged around the second surface 1020, covering all areas of the second surface 1020. In other embodiments, multiple electrically connected heating elements 401 arranged at intervals can be provided on the second surface 1020; or heating elements 401 can be individually provided at locations where a large amount of adhesive 300 is applied and where adhesive 300 is more likely to accumulate, such as at the corners of the housing assembly 100, all of which can achieve the effect of this embodiment.

[0067] To facilitate the maintenance and disassembly of the display device, the heating element 401 is fixed to the second surface 1020 using a thermosensitive adhesive 500 with a melting point greater than 300°C. In other embodiments, the heating element 401 can also be fixed to the side plate 102 using bolts; or a positioning pin can be provided on the second surface 1020, and a positioning hole matching the positioning pin can be made on the heating element 401 to achieve the installation and fixation of the heating element 401; or a buckle matching the heating element 401 can be provided on the second surface 1021 to fix the heating element 401. All of these methods can achieve the same effect as this embodiment.

[0068] In order to improve the fixing stability of the heating element 401, a slot 1023 matching the heating element 401 is provided on the second surface 1020, so that the heating element 401 can be embedded in the slot 1023 and fixed to the side plate 102.

[0069] Since the adhesive 300 overflowing from the third surface 1021 will pass through the heating element 401, in order to avoid the adhesive 300 accumulating on the end of the heating element 401 away from the first surface 1010, the height of the heating element 401 is set to be flush with the end of the heating element 401 away from the first surface 1010 and the end of the third surface 1021 near the accommodating space 103.

[0070] To further improve the fluidity of the adhesive 300 on the heating element 401, a hydrophobic and oleophobic coating 600 is provided on the surface of the heating element 401. In one application scenario, the hydrophobic and oleophobic coating 600 can be a viscosity modifier layer or an AF anti-fingerprint film layer. In other application scenarios, the hydrophobic and oleophobic coating 600 can also be other coating materials with a large surface water droplet angle, all of which can achieve the effect of this embodiment.

[0071] The adhesive 300 heated by the heating element 401 flows onto the first surface 1010 of the base plate 101 and accumulates, occupying space on the base plate 101 and adhering to the parts. To solve this problem, please refer to... Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of another embodiment of the housing assembly of this application. Figure 6 yes Figure 5 A cross-sectional structural diagram.

[0072] A base plate 101 has an adhesive receiving groove 1011, which is arranged around the periphery of the first surface 1010 to receive the adhesive 300 flowing onto the base plate 101 after passing through the heating element 401 which is arranged around the second surface 1020. In other embodiments, when the heating element 401 only covers a part of the second surface 1020, the adhesive receiving groove 1011 can be located on the first surface 1010 at a position corresponding to the heating element 401, or it can be arranged around the periphery of the first surface 1010 to receive other adhesive that has not been heated by the heating element 401.

[0073] To ensure that the adhesive 300 flows into the adhesive container 1011 after passing through the heating element 401, the orthographic projection of the heating element 401 on the first surface 1010 and the orthographic projection of the adhesive container 1011 on the first surface 1010 overlap by at least a portion. In other embodiments, to further ensure that the adhesive heated by the heating element 401 can flow completely into the adhesive container 1011, the orthographic projection of the heating element 401 on the first surface 1010 can also be located within the adhesive container 1011, thus achieving the effect of this embodiment.

[0074] The heating element 401 is only used to heat the adhesive 300 accumulated on the second surface 1020 after the display panel 200 is installed. Once all the overflowing adhesive 300 has flowed to the first surface 1010, the heating element 401 will stop working. At this time, the heating element 401 remains next to the panel layer 203 of the display panel 200. The heating element 401 shortens the clearance distance between the panel layer 203 of the display panel 200 and the side panel 102, affecting the performance of the display device. To solve this problem, please refer to... Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the first working state structure of another embodiment of the housing assembly of this application. Figure 8 This is a schematic diagram of the second working state structure of another embodiment of the housing assembly of this application.

[0075] The heating unit also includes a mounting component 402, which is attached to the second surface 1020 and fixed to the side plate 102. The mounting component 402 is fixed in the same way as the heating element 401 in the aforementioned embodiment, using a thermosensitive adhesive 500 with a melting point greater than 300. In other embodiments, the mounting component 402 can also be fixed using a positioning pin, a buckle, or other structure.

[0076] Mounting member 402 has a fifth surface 4020 located on the side away from the first surface 1010. A mounting groove 4021 is provided on the fifth surface 4020, extending in the direction from the fifth surface 4020 to the first surface 1010. The heating element 401 is partially embedded in the mounting groove 4021. A thermosensitive adhesive 403 for fixing the heating element 401 is provided between the heating element 401 and the inner wall of the mounting groove 4021. When the temperature reaches the melting point, the thermosensitive adhesive 403 melts and releases the heating element 401, so that the heating element 401 slides into the mounting groove 4021 along the extension direction of the mounting groove 4021.

[0077] In this embodiment, the heating element 401 is partially embedded and fixed in the mounting groove 4021 before heating operation. At this time, the heating element 401 is located next to the panel layer 203 of the display panel 200, and can heat the adhesive 300 overflowing from the third surface 1021, such as... Figure 7 As shown; after the work is completed, the heat-sensitive adhesive 403 melts and releases the heating element 401. The heating element 401 slides into the mounting groove 4021, which increases the distance between the display panel 200 and the side panel 102, and increases the clearance distance of the display panel 200, such as... Figure 8 As shown.

[0078] Understandably, in order to control the release timing of the heating element 401, the melting point of the thermal adhesive 403 should be greater than that of the liquid adhesive 300, but less than that of the thermal adhesive 500. In practice, the heating element 401 should first be kept running until the temperature of the second surface reaches the melting point of the liquid adhesive 300, keeping the liquid adhesive 300 in a molten and flowing state. After maintaining this state for a period of time, the heating element 401 should then be kept running until the temperature of the second surface reaches the melting point of the thermal adhesive 403, allowing the thermal adhesive 403 to melt and release the heating element 401.

[0079] To ensure that the adhesive 300 flows into the adhesive reservoir 1011 after passing through the heating element 401 and the mounting member 402, the orthographic projection of the mounting member 402 on the first surface 1010 overlaps with at least a portion of the orthographic projection of the adhesive reservoir 1011 on the first surface 1010. In other embodiments, to further ensure that the adhesive heated by the heating element 401 can flow completely into the adhesive reservoir 1011, the orthographic projection of the mounting member 402 on the first surface 1010 can also be located within the adhesive reservoir 1011, thus achieving the effect of this embodiment.

[0080] In order to ensure that the heating element 401 fits against the second surface 1020 and prevent adhesive from entering the gap between the heating element 401 and the second surface 1020, a recess 1024 corresponding to the position of the mounting member 402 is provided on the second surface 1020. The mounting member 402 is partially embedded in the recess 1024 and fixed to the side plate 102. The portion of the heating element 401 extending out of the mounting groove 4021 is fitted against the second surface 1020.

[0081] In this embodiment, the mounting member 402 has a sixth surface 4022 located near the accommodating space 103. In order to prevent the adhesive 300 from accumulating on the sixth surface 4022, the sixth surface 4022 is inclined towards the accommodating space 103 in the direction from the fifth surface 4020 to the first surface 1010.

[0082] To further prevent the adhesive 300 from accumulating on the surface of the mounting component 402, the material of the mounting component 402 can be selected as a conductive heating material, such as metal or semiconductor, and the mounting component 402 can be electrically connected to a power source so that the mounting component 402 and the heating element 401 work and generate heat synchronously.

[0083] Understandably, in this embodiment, in order to further improve the fluidity of the adhesive 300 on the surface of the heating element 401 and the mounting component 402, a hydrophobic and oleophobic coating can be provided on the surface of both the heating element 401 and the mounting component 402, as in the aforementioned embodiment. The material selection for the hydrophobic and oleophobic coating is the same as in the aforementioned embodiment, which can further prevent the adhesive from accumulating on the surface of the heating element 401 and the mounting component 402.

[0084] Please see Figure 9 , Figure 9 This is a flowchart illustrating one method of manufacturing the display device according to this application.

[0085] The production method includes:

[0086] S100: Performing a dispensing operation on a housing assembly, wherein the housing assembly includes a base plate having a first surface and a side plate disposed on the first surface around the periphery of the base plate, the side plate and the base plate cooperating to form an accommodating space, the side plate having a second surface located on the side closer to the accommodating space and a third surface located on the side farther from the base plate, the dispensing operation specifically being to dispense adhesive onto the third surface.

[0087] Specifically, the dispensing operation is performed automatically by a dispensing machine. The dispensing machine's working nozzle circles the third surface of the side panel to dispense the adhesive, which is then sprayed from the dispensing machine's working nozzle and adheres to the third surface.

[0088] S200: The display panel is covered onto the side panel, and the display panel is fixed to the side panel by adhesive on the third surface.

[0089] S300: The second surface is heated to reach the first threshold temperature.

[0090] Specifically, the selection of the first threshold should be based on the melting point of the adhesive. The first threshold should be greater than or equal to the melting point of the adhesive so that the adhesive remains in a molten state when passing through the second surface and can flow onto the base plate.

[0091] Meanwhile, in the aforementioned embodiment where the heating unit includes a heating element and a mounting component, since the heating element and the mounting component are fixed together by a heat-sensitive adhesive, in order to prevent the heat-sensitive adhesive from melting before the overflowing adhesive has completely flowed onto the base plate, the first threshold should be less than the melting point of the heat-sensitive adhesive.

[0092] In one embodiment, the second surface is heated by setting a heating unit on the second surface and controlling the heating unit to work continuously. When a first threshold is reached, the heating unit maintains the temperature of the second surface by working intermittently or at low power, so that the overflowing adhesive remains in a molten state and flows along the second surface to the base plate. In other embodiments, the temperature of the second surface can also be adjusted by increasing the ambient temperature.

[0093] In one embodiment, after step S300, the method further includes: continuing to heat the second surface until its temperature reaches a second threshold.

[0094] Specifically, when the heating unit includes a heating element and a mounting component, and the heating element and the mounting component are fixed together by a heat-sensitive adhesive, after the temperature of the second surface is heated to the first threshold and held for a period of time, the heating unit can be controlled to continue working to raise the temperature of the second surface to the second threshold.

[0095] The second threshold should be greater than the melting point of the heat-sensitive adhesive so that the heat-sensitive adhesive can melt and release the heating element. At the same time, the second threshold should be less than the melting point of the heat-sensitive adhesive between the heating unit and the second surface to prevent the heating unit from falling off.

[0096] By heating the second surface to a second threshold, the heating element can be slid into the mounting groove of the mounting component, increasing the distance between the display panel and the side panel, and increasing the clearance distance of the display panel.

[0097] The above are merely embodiments of this application and do not limit the scope of patent protection of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
