[0002] Display devices such as mobile phones and tablets have their screen panels glued to the mid-frame using adhesive and backing adhesive. When there is a component malfunction, it may be necessary to disassemble the panel and mid-frame for repair. In related technologies, a desolventizing agent is applied to the sides of the screen during disassembly. However, because there is a protective layer structure between the panel and the mid-frame, the desolventizing agent can easily cause the protective layer structure to delaminate, rendering the screen unusable. Summary of the Invention
[0003] The main objective of this application is to provide a display screen structure, a method for disassembling the display screen structure, and a display device. The aim is to at least solve the technical problem in the related art where, during disassembly, a desoldering liquid is applied to the side of the screen, but because there is a protective layer structure between the panel and the middle frame, the desoldering liquid can easily cause the protective layer structure to delaminate, rendering the screen unusable.
[0004] To achieve the above objectives, an embodiment of this application proposes a display screen structure, comprising:
[0005] A panel having an inner mounting area, the mounting area comprising a first area and at least one second area, the area of the second area being smaller than that of the first area;
[0006] A protective component includes a buffer layer and a protective layer, the buffer layer being adhered to the inner side of the panel, and the protective layer being adhered to the inner side of the buffer layer. The protective layer includes a first protective portion and at least one second protective portion disposed separately, the first protective portion being disposed in a first region, and the second protective portion being disposed in a second region; and...
[0007] The middle frame is bonded to the other side of the protective layer.
[0008] This application also proposes a method for disassembling a display screen structure, the display screen structure comprising:
[0009] A panel having an inner mounting area, the mounting area comprising a first area and at least one second area, the area of the second area being smaller than that of the first area;
[0010] A protective component includes a buffer layer and a protective layer, the buffer layer being adhered to the inner side of the panel, and the protective layer being adhered to the inner side of the buffer layer. The protective layer includes a first protective portion and at least one second protective portion disposed separately, the first protective portion being disposed in a first region, and the second protective portion being disposed in a second region; and...
[0011] The middle frame is bonded to the other side of the protective layer;
[0012] The method for disassembling the display screen structure includes:
[0013] Apply the desolvation solution to the bonding area between the buffer layer and the panel corresponding to the second region;
[0014] Separate the panel from the portion of the buffer layer corresponding to the second region;
[0015] Separate the panel from the portion of the buffer layer corresponding to the first region.
[0016] This application also proposes a display device, including the above-described display screen structure.
[0017] In the technical solution of this application embodiment, the display screen structure includes a panel, a protective component, and a mid-frame. The inner side of the panel has a mounting area, which includes a first area and at least one second area. The area of the second area is smaller than that of the first area. The protective component includes a buffer layer and a protective layer. The buffer layer is adhered to the inner side of the panel, and the protective layer is adhered to the inner side of the buffer layer. The protective layer includes a first protective part and at least one second protective part that are separately arranged. The first protective part is disposed in the first area, and the second protective part is disposed in the second area. The mid-frame is adhered to the other side of the protective layer. With this configuration, when the display screen is mounted... When disassembling the panel and the middle frame, a dissolving agent is applied to the bonding area between the buffer layer and the panel, corresponding to the second area. This dissolving agent causes the adhesive between the panel and the buffer layer to loosen, gradually separating the panel from the overall buffer layer and completing the disassembly. Since the area of the second region is smaller than that of the first region, meaning the corresponding second protective portion is smaller than the proportion of the first protective portion in the overall protective layer, even if the dissolving agent penetrates between the second protective portion and the buffer layer, causing delamination, the overall protective layer can still maintain its protective performance, thereby improving the disassembly success rate and reducing the screen scrap rate.

[0030] Display devices such as mobile phones and tablets have screen panels that are glued to the mid-frame using adhesive and backing adhesive. When there is a component malfunction, it may be necessary to disassemble the panel and mid-frame for repair. In related technologies, a desiccant is applied to the sides of the screen during disassembly. However, because there is a protective layer structure between the panel and the mid-frame, it is difficult to determine whether the adhesion between the panel and the protective layer structure or the adhesion within the protective layer structure is stronger after the desiccant is applied. During disassembly, the protective layer structure is prone to delamination, damaging very thin copper foils, graphite sheets, etc. in the protective layer structure, rendering the screen unusable and difficult to repair.
[0031] The main objective of this application is to provide a display screen structure, a method for disassembling the display screen structure, and a display device. The aim is to at least solve the technical problem in the related art where, during disassembly, a desoldering liquid is applied to the side of the screen, but because there is a protective layer structure between the panel and the middle frame, the desoldering liquid can easily cause the protective layer structure to delaminate, rendering the screen unusable.
[0032] Please see Figure 1 and Figure 2 In this embodiment of the application, the display screen structure 100 includes a panel 1, a protective component 2, and a middle frame 3. The inner side of the panel 1 has an installation area, which includes a first area 101 and at least one second area 102. The area of the second area 102 is smaller than that of the first area 101. The protective component 2 includes a buffer layer 21 and a protective layer 22. The buffer layer 21 is adhered to the inner side of the panel 1, and the protective layer 22 is adhered to the inner side of the buffer layer 21. The protective layer 22 includes a first protective part 221 and at least one second protective part 222 that are separately arranged. The first protective part 221 is disposed in the first area 101, and the second protective part 222 is disposed in the second area 102. The middle frame 3 is adhered to the other side of the protective layer 22.
[0033] In the technical solution of this application embodiment, the display screen structure 100 includes a panel 1, a protective component 2, and a middle frame 3. The inner side of the panel 1 has an installation area, which includes a first area 101 and at least one second area 102. The area of the second area 102 is smaller than that of the first area 101. The protective component 2 includes a buffer layer 21 and a protective layer 22. The buffer layer 21 is adhered to the inner side of the panel 1, and the protective layer 22 is adhered to the inner side of the buffer layer 21. The protective layer 22 includes a first protective part 221 and at least one second protective part 222 that are separately arranged. The first protective part 221 is disposed in the first area 101, and the second protective part 222 is disposed in the second area 102. The middle frame 3 is adhered to the protective layer 22. On the other side; with this configuration, when disassembling the panel 1 and the middle frame 3, a debonding liquid is applied to the bonding area between the buffer layer 21 and the panel 1 at the portion corresponding to the second region 102. This causes the adhesive between the panel 1 and the buffer layer 21 to debond under the action of the debonding liquid, gradually separating the panel 1 from the entire buffer layer 21 and completing the disassembly. Since the area of the second region 102 is smaller than that of the first region 101, that is, the corresponding second protective part 222 is smaller than the proportion of the first protective part 221 in the entire protective layer 22, even if the debonding liquid penetrates between the second protective part 222 and the buffer layer 21 and causes delamination, the entire protective layer 22 can still maintain its protective performance, thereby improving the disassembly success rate and reducing the screen scrap rate.
[0034] The buffer layer 21 is used to cushion the panel 1 and can be made of various materials. In some embodiments, the buffer layer 21 can be foam or silicone, etc.
[0035] This design does not limit the specific type of debonding liquid. When selecting the debonding liquid, it depends on the adhesive between the panel 1 and the buffer layer 21. If the adhesive between the panel 1 and the buffer layer 21 loses its stickiness when it comes into contact with water, then water is used as the debonding liquid. If the adhesive between the panel 1 and the buffer layer 21 loses its stickiness when it comes into contact with alcohol, then alcohol is used as the debonding liquid.
[0036] In this embodiment, the protective layer 22 can be made of different materials depending on its protective function. In some embodiments, when the protective layer 22 is used to provide electromagnetic shielding and anti-static functions for the display screen structure 100, it can be copper foil or aluminum foil, etc.; in some embodiments, when the protective layer 22 is used to provide heat dissipation protection for the display screen structure 100, it can be graphite sheet or thermally conductive silicone sheet, etc. Of course, the protective layer 22 can also provide electromagnetic shielding, anti-static, and heat dissipation protection functions simultaneously. For example, in some embodiments, the protective layer 22 is a stack of aluminum foil and graphite sheet.
[0037] To ensure the protective function of the protective layer 22 for the display screen structure 100 as much as possible, it is understood that the proportion of the second protective part 222 in the overall protective layer 22 should not be too large, so as to avoid excessive loss of the protective performance of the overall protective layer 22 when the desolvating liquid penetrates between the second protective part 222 and the buffer layer 21 and causes delamination. Therefore, in this embodiment, the ratio of the area of the second region 102 to the area of the first region 101 is less than 0.1, that is, the second protective part 222 occupies at most 0.1 of the first protective part 221. Even if the second protective part 222 is damaged during disassembly, it will not have a significant impact on the overall protective effect of the protective layer 22.
[0038] Please refer to Figure 3 , Figure 4 and Figure 5 In this embodiment, the second region 102 can be one or more, such as two or three, and the corresponding second protective part 222 can also be multiple. When the proportion of the second protective part 222 in the overall protective layer 22 is constant, the more second protective parts 222 there are, the less dissolving liquid is required for each second region 102 during actual disassembly. Thus, while waiting for the dissolving liquid to dissolve the adhesive between the panel 1 and the buffer layer 21, the dissolving liquid is less likely to flow to the first region 101, making it less likely for the first protective part 221 and the buffer layer 21 to separate, and also less likely for the adhesive between the second protective part 222 and the buffer layer 21 to lose its stickiness. This reduces the possibility of damage to the first protective part 221 and the second protective part 222, improving the disassembly yield. When there is only one second protective part 222, the assembly of the entire protective layer is easier. In summary, different numbers of the second region 102 have different effects, and the appropriate number can be selected according to actual needs during design.
[0039] Understandably, during actual disassembly, the disassembly begins from the second region 102. The location of the second region 102, i.e. the location of the second protective part 222, can be set in the middle or at the edge. If the second region 102 is set in the middle, after the glue corresponding to the second region 102 between the panel 1 and the buffer layer 21 dissolves, the surrounding area remains stuck together, resulting in greater resistance and more effort when disassembling the first region 101. Therefore, in this embodiment, the thickness direction of the panel 1 is the first direction, and one of the width and length directions of the panel 1 is the second direction. The panel 1 has a first side 11 located in the second direction, and the second protective part 222 is disposed adjacent to the first side 11. In this way, by setting the second region 102 at the edge, it is more convenient to disassemble the part of the panel 1 corresponding to the first region 101. At the same time, it is also more convenient to apply the dissolving liquid, as it can be applied directly. However, when the second region 102 is located in the middle, it is necessary to use an external tool such as a syringe to introduce the dissolving liquid between the panel 1 and the buffer layer 21.
[0040] In some embodiments, the first side 11 can be one side of the panel 1 in the width direction or one side in the length direction. It is understood that when the first side 11 is one side in the length direction, such as... Figure 4 As shown, when disassembling towards the second region 102, the disassembly is performed gradually along the length direction, resulting in a smaller contact area between the panel 1 and the buffer layer 21, making disassembly easier. Therefore, in one embodiment of this application, the second direction is the length direction of the panel 1.
[0041] As described above, the closer the second protective part 222 is to the edge, the easier it is to disassemble. In some embodiments, the other direction of the width and length of the panel 1 is a third direction, and the panel 1 has a second side 12 in the third direction; the second protective part 222 is provided near the junction of the first side 11 and the second side 12. Thus, the second protective part 222 is provided at the corner position. After applying the desiccant, the portion of the panel 1 and the buffer layer 21 corresponding to the second region 102 is not bonded on both sides, resulting in less resistance from the adhesive and easier disassembly.
[0042] When applying the desolvent, it is usually necessary to coat both sides of the screen to facilitate disassembly, as shown in the attached image. Figure 2As shown, when coating the first side 11 and then coating the second side 12, the dissolving liquid from the first side 11 may flow to the bonding area between the panel 1 and the buffer layer 21 corresponding to the first region 101, potentially leading to delamination between the first protective part 221 and the buffer layer 21. Therefore, in this embodiment, at least one injection hole 31 is provided on the middle frame 3, corresponding to the second region 102, for injecting the dissolving liquid. This arrangement guides the dissolving liquid through the injection hole 31, directing it to the second region 102. When injecting the dissolving liquid, the panel 1 can be placed downwards, allowing the dissolving liquid to gradually dissolve downwards under gravity at the bonding area between the panel 1 and the buffer layer 21. This increases the difficulty of the dissolving liquid penetrating between the first protective part 221 and the buffer layer 21, reducing the likelihood of delamination between the first protective part 221 and the buffer layer 21.
[0043] Please refer to Figure 4 and Figure 5 The injection hole 31 on the middle frame 3 can correspond to one or more of the second region 102. When the area of the same second region 102 remains fixed, the fewer the number of injection holes 31, the less liquid needs to be injected into each injection hole 31, and the less likely the liquid will flow into the first region 101. The fewer the number of injection holes 31, the fewer injections are needed, and the simpler the process. Of course, if... Figure 4 As shown, when the span of the second region 102 is large, setting multiple injection holes 31 will make disassembly easier; at the same time, the display screen structure 100 has many internal components, and there are parts on the middle frame 3 that need to be avoided or where other components need to be installed. Therefore, the position of the second region 102 and the number and position of the injection holes 31 need to be considered comprehensively.
[0044] It is understood that the closer the injection hole 31 is to the edge, the less likely the liquid will flow between the first protective part 221 and the buffer layer 21. Therefore, in this embodiment, the distance between the injection hole 31 and the first side 11 in the second direction is less than 4mm, and can be 1mm, 2mm, 3mm, 4mm, etc.
[0045] It should be noted that the protective layer 22 and the middle frame 3 are also bonded together with adhesive. The presence of adhesive will hinder the flow of curing liquid from the injection hole 31 to the area between the panel 1 and the buffer layer 21. Therefore, the adhesive layer between the protective layer 22 and the middle frame 3 needs to be separated. If the protective layer 22 and the middle frame 3 are directly bonded together with adhesive, a post can be inserted at the position corresponding to the injection hole 31 before bonding. After the adhesive solidifies, the post can be pulled out to form a clearance hole. If the protective layer 22 and the middle frame 3 are bonded together with adhesive and glue, a clearance hole corresponding to the injection hole 31 can be directly opened on the adhesive before bonding.
[0046] To further reduce the possibility of the liquid dissolving flowing between the first protective section 221 and the buffer layer 21, in some embodiments, please refer to... Figure 2 A first isolation layer 4 is coated on the side of the first protective part 221 facing the second protective part 222 where it adheres to the buffer layer 21. Thus, when the dissolving liquid is coated or injected into the second region 102 through the injection hole 31, the first isolation layer 4 can effectively prevent the dissolving liquid from flowing into the space between the first protective part 221 and the buffer layer 21 through the gap between the first protective part 221 and the second protective part 222, thereby reducing the possibility of delamination between the first protective part 221 and the buffer layer 21 and improving the disassembly yield.
[0047] In some embodiments, a second isolation layer 5 is coated on the periphery of the second protective part 222 at the bonding point with the buffer layer 21. By providing the second isolation layer 5, the possibility of the desolvation liquid flowing between the second isolation layer 5 and the buffer layer 21 can be reduced, thereby reducing the possibility of damage to the second protective part 222 and ensuring the integrity of the protective layer 22 as much as possible.
[0048] The specific materials of the first isolation layer 4 and the second isolation layer 5 depend on the selected desolvation liquid. For example, when the desolvation liquid is water, the first isolation layer 4 and the second isolation layer 5 can be made of some waterproof adhesive or waterproof coating. This design does not impose any restrictions, as long as it can prevent the penetration of the desolvation liquid.
[0049] This application embodiment also proposes a method for disassembling a display screen structure 100. The display screen structure 100 includes a panel 1, a protective component 2, and a middle frame 3. The inner side of the panel 1 has an installation area, which includes a first area 101 and at least one second area 102. The area of the second area 102 is smaller than that of the first area 101. The protective component 2 includes a buffer layer 21 and a protective layer 22. The buffer layer 21 is adhered to the inner side of the panel 1, and the protective layer 22 is adhered to the inner side of the buffer layer 21. The protective layer 22 includes a first protective part 221 and at least one second protective part 222 that are separately arranged. The first protective part 221 is disposed in the first area 101, and the second protective part 222 is disposed in the second area 102. The middle frame 3 is adhered to the other side of the protective layer 22. The method for disassembling the display screen structure 100 includes:
[0050] S100: Apply the desoldering liquid to the bonding area between the buffer layer 21 and the panel 1, corresponding to the second region 102.
[0051] S200: Separate the panel 1 from the portion of the buffer layer 21 corresponding to the second region 102;
[0052] S300: Separate the panel 1 from the portion of the buffer layer 21 corresponding to the first region 101.
[0053] In the technical solution of this application embodiment, when disassembling the panel 1 and the middle frame 3, a debonding liquid is applied to the bonding area between the portion of the buffer layer 21 corresponding to the second region 102 and the panel 1. This causes the adhesive between the panel 1 and the buffer layer 21 to debond under the action of the debonding liquid. First, the panel 1 is separated from the portion of the buffer layer 21 corresponding to the second region 102, and then the portion of the panel 1 is separated from the buffer layer 21 corresponding to the first region 101, thus completing the disassembly. Since the area of the second region 102 is smaller than that of the first region 101, that is, the corresponding second protective part 222 is smaller than the proportion of the first protective part 221 in the overall protective layer 22, even if the debonding liquid penetrates between the second protective part 222 and the buffer layer 21 and causes delamination, the overall protective layer 22 can still maintain its protective performance, thereby improving the disassembly success rate and reducing the screen scrap rate.
[0054] It is understandable that, since the dissolving liquid is not applied to the first area 101, it requires considerable force to separate the panel 1 from the portion of the buffer layer 21 corresponding to the first area 101. Excessive force may not only damage the first protective part 221, but may even damage the panel 1. In order to improve the convenience and success rate of disassembly, in some embodiments, the steps between steps S100 include preheating the display structure 100 according to preset parameters, so that the adhesive between the buffer layer 21 and the panel 1 softens, making disassembly easier, and also reducing the amount of dissolving liquid required, thereby further reducing the possibility of the dissolving liquid flowing to the first area 101.
[0055] The preset parameters include a preheating temperature. Since the protective layer 22 and the buffer layer 21 are also bonded together with adhesive, the preheating temperature should not be too high. Otherwise, the first protective part 221 may delaminate from the buffer layer 21, resulting in a lower success rate of disassembly. It may also cause other components of the display screen structure 100 to be damaged by heat. Of course, the preheating temperature should not be too low either, otherwise it will be difficult to soften the adhesive or a longer preheating time will be required. In summary, the preheating temperature is between 80 degrees Celsius and 85 degrees Celsius, and can be 80, 82, 85 degrees Celsius, etc.
[0056] The preset parameters include preheating time. The preheating time should not be too short or too long. If it is too short, it will not achieve a good softening effect and disassembly will still be difficult. If it is too long, it may over-soften, causing the first protective part 221 to delaminate from the buffer layer 21. In summary, the preheating time is between 10 minutes and 15 minutes, such as 10, 13, or 15 minutes.
[0057] In one embodiment of this application, the preset parameters include a preheating temperature between 80 and 85 degrees Celsius, and a preheating time between 10 and 15 minutes. When both the preheating temperature and the preheating time are satisfied, preheating will not cause delamination between the first protective part 221 and the buffer layer 21, while reducing the need for dissolution liquid and improving the convenience and success rate of disassembly.
[0058] Before step S200, a preset reaction time is required to allow the dissolving liquid and adhesive to react. The preset reaction time should not be too long, so as to prevent the dissolving liquid from flowing to the first area 101 or other places and affecting the success rate of disassembly. Of course, the preset reaction time should not be too short either, as it may result in insufficient reaction between the adhesive and the dissolving liquid, making disassembly more difficult. Therefore, the preset reaction time is set between one and two minutes, which allows the dissolving liquid and adhesive to react sufficiently without the dissolving liquid flowing to other places.
[0059] During steps S200 and S300, the panel 1 can be disassembled by using a suction cup to hold it in place or by using tape to stick it to the panel 1.
[0060] Another embodiment of this application also proposes a method for disassembling a display screen structure 100. The display screen structure 100 includes a panel 1, a protective component 2, and a middle frame 3. The inner side of the panel 1 has an installation area, which includes a first area 101 and at least one second area 102. The area of the second area 102 is smaller than that of the first area 101. The protective component 2 includes a buffer layer 21 and a protective layer 22. The buffer layer 21 is adhered to the inner side of the panel 1, and the protective layer 22 is adhered to the inner side of the buffer layer 21. The protective layer 22 includes a first protective part 221 and at least one second protective part 222 that are separately arranged. The first protective part 221 is disposed in the first region 101, and the second protective part 222 is disposed in the second region 102. The middle frame 3 is adhered to the other side of the protective layer 22. The thickness direction of the panel 1 is a first direction, and one of the width and length directions of the panel 1 is a second direction. The panel 1 has a first side 11 located in the second direction. The second protective part 222 is disposed adjacent to the first side 11. At least one injection hole 31 is disposed on the middle frame 3, and the injection hole 31 is disposed corresponding to the second region 102 for injecting a liquid to dissolve the solidification fluid. The method for disassembling the display screen structure 100 includes:
[0061] S100': Injecting a desolvation liquid through the injection hole 31, so that the desolvation liquid flows to the bonding point between the buffer layer 21 and the second region 102.
[0062] S200': Separate the panel 1 from the portion of the buffer layer 21 corresponding to the second region 102;
[0063] S300': Separate the panel 1 from the portion of the buffer layer 21 corresponding to the first region 101.
[0064] In the technical solution of this application embodiment, when disassembling the panel 1 and the middle frame 3, a dissolving liquid is injected through the injection hole 31, so that the dissolving liquid flows to the bonding area between the part of the buffer layer 21 corresponding to the second region 102 and the panel 1, so that the glue between the panel 1 and the buffer layer 21 is dissolved under the action of the dissolving liquid. The panel 1 is first separated from the part of the buffer layer 21 corresponding to the second region 102, and then the part of the panel 1 corresponding to the buffer layer 21 corresponding to the first region 101 can be separated to complete the disassembly. Since the area of the second region 102 is smaller than that of the first region 101, that is, the corresponding second protective part 222 is smaller than the proportion of the first protective part 221 in the overall protective layer 22, even if the dissolving liquid penetrates between the second protective part 222 and the buffer layer 21 and causes delamination, the overall protective layer 22 can still maintain its protective performance, thereby improving the disassembly success rate and reducing the screen scrap rate.
