[0038] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to indicate the same or similar elements, unless otherwise represented. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0039] In the field of display technology, there are two different display screen assembly technologies, namely frame bonding and full bonding. They are used in the manufacturing process to combine a touch panel (TP) with a liquid crystal display (LCD) or other panel. Frame bonding generally refers to bonding the edge part of the touch panel to the peripheral frame of the liquid crystal display (display screen outer frame), usually using double-sided tape or other types of adhesive to fix the touch panel.

[0040] In the production process of a display screen using frame bonding technology, there are cases where the display screen needs to be disassembled for repair due to yield problems of the touch panel, display panel, etc. or misalignment during the bonding process of the display screen outer frame and the touch panel. In the disassembly process, the display screen outer frame needs to be separated from the touch panel, but the display screen outer frame and the touch panel or display panel are bonded together by strong glue, making disassembly difficult. Especially in the field of large-size display screens, the touch panel glass is thick, and there is no structure around to support the touch panel, and there is no structure on the front side to press the touch panel. If the bonding strength between the display screen outer frame and the touch panel is not enough, there is a risk of separation, which poses a great safety hazard. Therefore, VHB (Very High Bond) tape and AB glue (usually refers to two-component epoxy resin glue) are used in combination for bonding. Although this reduces the safety hazard, it greatly increases the difficulty of disassembling the display screen.

[0041] In existing disassembly technology, the display screen outer frame and the touch panel bonded thereto are placed together on a heating platform for heating. After the glue layer between the display screen outer frame and the touch panel fails and the adhesion becomes poor, a fishing line is used to cut around to separate the touch panel and the display screen outer frame. However, the fishing line is prone to breaking during the separation process, which not only increases production costs but also greatly reduces disassembly efficiency.

[0042] Secondly, for ease of transportation, the display screen outer frame is generally a segmented frame, i.e., different bezels are spliced together by splicing aluminum strips and splicing screws. In existing display screen outer frames, the splicing screws used for fastening at the splicing part between the bezels are bonded together with VHB glue and / or AB glue. If the display screen outer frame needs to be disassembled, it must first be separated from the touch panel before the display screen outer frame can be disassembled, resulting in low disassembly efficiency.

[0043] Reference Figures 1-6 The present application provides a frame structure 1 comprising a frame body 10, a connecting assembly 30, and a disassembly assembly 40. The frame body 10 comprises a first bezel 11 and a second bezel 12 arranged oppositely, and a third bezel 13 and a fourth bezel 14 arranged oppositely. The first bezel 11, the second bezel 12, the third bezel 13, and the fourth bezel 14 are each provided with a splicing part 20 at both ends, and the splicing part 20 is located on the inner frame side of the frame body 10.

[0044] It should be noted that the frame structure 1 in the present application is a sectional frame. Therefore, the splicing part 20 can also be understood as a part of each frame for connecting with other frames. The splicing part 20 is generally integrally formed with other parts of the frame. In the present application, in order to clearly and accurately describe the connection relationship between the frames, the splicing part 20 is described separately.

[0045] In some embodiments, the materials of the first frame 11, the second frame 12, the third frame 13 and the fourth frame 14 are selected from aluminum materials. In one embodiment, the frame structure 1 is configured as a rectangular aluminum frame.

[0046] Continuing to refer to Figure 2 The splicing part 20 has a first mating surface 21, a second mating surface 22 and a third mating surface 23. The first mating surface 21 and the second mating surface 22 are perpendicular, and the third mating surface 23 is located in the area surrounded by the first mating surface 21 and the second mating surface 22, and the third mating surface 23 of adjacent two frames is correspondingly arranged. The connecting assembly 30 includes a first connecting piece 31 and a second connecting piece 32. The first connecting piece 31 and the second connecting piece 32 are both arranged inside each frame through the third mating surface 23, the first connecting piece 31 is installed at or near the first mating surface 21, and the second connecting piece 32 is installed at or near the second mating surface 22.

[0047] Specifically, continuing to refer to Figure 6 In the production process of the display screen, one side of the frame structure 1 is used for bonding with the touch screen 4, and the other side is used for mounting other display panels or structures. Therefore, the side of the frame structure 1 bonded with the touch screen 4 is defined as the bonding surface, and the side away from the touch screen 4 is defined as the mounting surface. The surface of the side wall of the area surrounded by each frame is the inner frame surface.

[0048] In the present embodiment, the first mating surface 21 is located on the inner frame surface, and the second mating surface 22 is located on the mounting surface. This arrangement avoids bonding the mating surface of each frame with the edge of the touch screen 4, and allows the frame structure 1 to be disassembled into four independent frames when the frame structure 1 is not separated from the touch screen 4, and the separation operation of each independent frame from the touch screen 4 is performed. This operation can greatly improve the efficiency of disassembling the display screen and reduce the cost of disassembling.

[0049] In some embodiments, the first connecting piece 31 and the second connecting piece 32 are in the shape of a strip, and the material is selected from aluminum materials. The frames are spliced by splicing aluminum strips (i.e., the first connecting piece 31 and the second connecting piece 32). The aluminum strips are inserted into each frame through the third mating surface 23, and then matched with the mating surface of the splicing part 20 to realize the connection between the frames.

[0050] In some embodiments, the frame structure 1 has four first connecting pieces 31 and four second connecting pieces 32. It can also be understood that the frame structure 1 has a total of eight splicing aluminum strips. At the connection of each two side frames, there are two splicing aluminum strips, i.e., one first connecting piece 31 and one second connecting piece 32.

[0051] In some embodiments, the disassembling components 40 are evenly distributed on the first side frame 11, the second side frame 12, the third side frame 13 and the fourth side frame 14, respectively. When the frame structure 1 is disassembled into independent side frames, the first side frame 11, the second side frame 12, the third side frame 13 and the fourth side frame 14 also need to be peeled off from the adhesive layer 2 in sequence to achieve separation from the touch screen 4.

[0052] In the peeling process from the adhesive layer 2, the operator can install a disassembling tool on the disassembling component 40, which serves as a support for the disassembling tool, i.e., taking the disassembling component 40 as a fulcrum. When the disassembling tool is displaced in a certain direction, the lever force between the disassembling tool and the disassembling component 40 causes the side frames to gradually peel off from the adhesive layer (VHB glue and / or AB glue), thereby achieving separation of the side frames from the touch screen 4.

[0053] In the present embodiment, by providing the disassembling components 40, the time for disassembling and separating the side frames from the touch screen 4 can be reduced to improve the disassembling efficiency, and the disassembling tool can be operated uniformly by a mechanical device to save manpower and further reduce costs.

[0054] In some embodiments, the number of disassembling components 40 provided on each side frame can be customized according to the size and requirements of the display screen. It is particularly worth noting that the position of the disassembling component 40 needs to avoid the part of the wire outlet on the edge of the touch screen 4 to which it is bonded, and the position of the disassembling component 40 is adjusted accordingly according to the position of the wire outlet.

[0055] In one embodiment, taking a 65-inch display screen as an example, four disassembling components 40 are provided on the first side frame 11. Three disassembling components 40 are provided on the second side frame 12, the third side frame 13 and the fourth side frame 14, respectively. This arrangement can not only ensure the disassembling efficiency of the display screen, but also further reduce the production cost of the frame structure 1 by optimizing the number of disassembling components 40.

[0056] In some embodiments, referring to Figure 2 and Figure 4 Each disassembling component 40 includes a support piece 41 and a disassembling hole 42 provided on the support piece 41. The support piece 41 is located on the inner frame side of the frame body 10, and the disassembling hole 42 is provided on the support piece 41 for connecting an external disassembling tool to achieve disassembly of the frame structure 1.

[0057] In one embodiment, the support 41 is configured as a sheet structure with hollows 43 at the bottom, and the hollows 43 are located between the disassembling holes 42. Preferably, the hollows 43 are configured as long circular holes. This configuration can effectively disperse the force exerted by the disassembling tool, so as to ensure the rigidity and stability of the frames during separation from the glue layer.

[0058] In some embodiments, continuing to refer to Figure 2 , the disassembling tool can be configured as a crowbar 5. One end of the crowbar 5 is provided with a connecting hole 53 corresponding to the disassembling hole 42. The disassembling hole 42 and the connecting hole 53 are connected by a crowbar screw 54. Preferably, the number of disassembling holes 42, connecting holes, and crowbar screws is 2.

[0059] In some embodiments, continuing to refer to Figure 4 , the third frame 13 and the fourth frame 14 each include a main body part 130 and a bent part 140, the bent part 140 is located at both ends of the main body part 130, and the bent part 140 is perpendicular to the main body part 130, so that the third frame 13 and the fourth frame 14 are in a groove shape. The splicing part 20 is located on the bent part 140, and the bent part 140 of the third frame 13 and the fourth frame 14 cooperates with the first frame 11 and the second frame 12 to form the frame body 10.

[0060] In this embodiment, the bent parts 140 of the third frame 13 and the fourth frame 14 in a groove shape are correspondingly arranged, which can also be understood that the third cooperation faces 23 of the third frame 13 and the fourth frame 14 located on the bent parts 140 are opposite to each other, the first connecting piece 31 and the second connecting piece 32 respectively extend into the first frame 11, the second frame 12, the third frame 13, and the fourth frame 14 from the third cooperation faces 23 of the frames, and then cooperate with the first cooperation face 21 and the second cooperation face 22 respectively, so as to form a rectangular frame structure 1.

[0061] In some embodiments, the length of the bent part 140 is less than the length of the first connecting piece 31 and the second connecting piece 32. The bent part 140 only needs to accommodate part of the first connecting piece 31 and the second connecting piece 32 to complete the connection function.

[0062] In some embodiments, the size of the part of the first connecting piece 31 and the second connecting piece 32 located in the first frame 11 and the second frame 12 is equal to the size of the part of the first connecting piece 31 and the second connecting piece 32 located in the bent part 140. This configuration helps to stabilize the connection between the frames.

[0063] In some embodiments, referring to Figure 5The first frame 11 and the second frame 12 each include a first accommodating cavity 110 and a second accommodating cavity 120. End faces of the first accommodating cavity 110 and the second accommodating cavity 120 form a third matching surface 23. The first accommodating cavity 110 and the second accommodating cavity 120 each pass through the first frame 11 and the second frame 12, and the first accommodating cavity 110 is used for accommodating the first connecting piece 31, and the second accommodating cavity 120 is used for accommodating the second connecting piece 32.

[0064] It can be understood that the first frame 11 and the second frame 12 are hollow frames. The first connecting piece 31 and the second connecting piece 32 are locked by matching with the respective matching surfaces in the respective frames. When disassembling the frame structure 1, after canceling the matching of the first connecting piece 31 and the second connecting piece 32 with the corresponding matching surfaces, the first connecting piece 31 is moved into the first accommodating cavity 110, and the second connecting piece 32 is moved into the second accommodating cavity 120, that is, the first connecting piece 31 and the second connecting piece 32 are all placed in the first frame 11 and the second frame 12. To achieve the independence between the respective frames, the disassembly of the frame structure 1 is completed.

[0065] Specifically, when transporting or reassembling the disassembled frame, the first connecting piece 31 and the second connecting piece 32 need to be separated from the frame for storage or reconnection of the respective frames. Since the first accommodating cavity 110 and the second accommodating cavity 120 pass through the first frame 11 and the second frame 12, it is only necessary to move the first frame 11 and the second frame 12 in a suitable direction, so that the first connecting piece 31 and the second connecting piece 32 move along the first accommodating cavity 110 and the second accommodating cavity 120, so that the first connecting piece 31 and the second connecting piece 32 are moved out of any one of the two ends of the first frame 11 and the second frame 12. The separation of the connecting piece and the frame can be easily realized, and the transportation and assembly of the frame structure 1 are facilitated, and the production efficiency is improved.

[0066] In some embodiments, referring to Figure 4 The first connecting piece 31 has a first connecting surface 311, and the second connecting piece 32 has a second connecting surface 321. The first connecting surface 311 corresponds to the first matching surface 21, and the second connecting surface 321 corresponds to the second matching surface 22.

[0067] In this embodiment, the first connecting surface 311 is consistent with the first matching surface 21, and both are located on the inner frame surface of the frame structure 1. In the separation process of the first connecting piece 31 and the respective frames, the first connecting piece 31 is not affected by the adhesive layer 2, and the disassembly can be directly completed without waiting for the frame structure 1 to be separated from the touch screen 4 before disassembly. Not only the disassembly efficiency of the frame structure 1 and the touch screen 4 is improved, but also the disassembly cost is effectively reduced.

[0068] Similarly, the second connecting surface 321 and the second mating surface 22 are identical and are both located on the mounting surface of the frame structure 1. During the separation process of the second connector 32 and each frame, it is not affected by the touch screen 4 and the adhesive layer, and can be directly disassembled without waiting for the frame structure 1 to separate from the touch screen 4. This also improves disassembly efficiency and reduces costs.

[0069] In some embodiments, the frame structure 1 further includes a locking assembly. The locking assembly includes a plurality of first locking members 51 and second locking members 52, the first locking members 51 being used to fasten the first connecting member 31 and each frame, and the second locking members 52 being used to fasten the second connecting member 32 and each frame.

[0070] Specifically, the discussion will take the connection between the splicing portion 20 at one end of the first frame 11 and the splicing portion 20 at one end of the third frame 13 as an example. (Refer to...) Figure 2 Part of the first connector 31 extends from the third mating surface 23 of the first frame 11 into the first frame 11, so that part of the first connecting surface 311 corresponds to the first mating surface 21 of the splicing part 20 on the first frame 11. Then, another part of the first connector 31 extends from the third mating surface 23 of the third frame 13 into the third frame 13, so that the remaining part of the first connecting surface 311 corresponds to the first mating surface 21 of the splicing part 20 on the third frame 13. Finally, the first locking member 51 passes through the first mating surface 21 and connects with the first connecting surface 311 in sequence to realize the splicing between the first frame 11 and the third frame 13.

[0071] Similarly, a portion of the second connector 32 extends into the first frame 11 from the third mating surface 23, such that a portion of the second connecting surface 321 corresponds to the second mating surface 22 of the splicing portion 20 on the first frame 11. Then, another portion of the second connector 32 extends into the third frame 13 from the third mating surface 23, such that the remaining portion of the second connecting surface 321 corresponds to the second mating surface 22 of the splicing portion 20 on the third frame 13. Finally, the second locking member 52 passes through the second mating surface 22 and connects with the second connecting surface 321 to achieve splicing between the first frame 11 and the third frame 13.

[0072] It should be noted that the order in which the connectors extend into the frame during the splicing of adjacent frame pieces is not limited. Taking the above example, during the splicing of the first frame 11 and the third frame 13, the first connector 31 and the second connector 32 can either extend into the first frame 11 first, and then the third frame 13 is spliced ​​accordingly based on the position of the connectors, or they can extend into the third frame 13 first, and the first frame 11 is shifted according to the position of the connectors to achieve the splicing. The specific choice depends on the actual situation and is not limited here.

[0073] In some embodiments, continuing to refer to Figure 2 and Figure 4 , a plurality of first connecting holes 310 are formed on the first connecting surface 311, a plurality of second connecting holes 320 are formed on the second connecting surface 321, a plurality of first matching holes 210 are formed on the first matching surface 21, and a plurality of second matching holes 220 are formed on the second matching surface 22.

[0074] In one embodiment, the first connecting holes 310 and the second connecting holes 320 are configured as threaded holes, the first matching holes 210 and the second matching holes 220 are configured as circular through holes, and the first locking members 51 and the second locking members 52 are configured as locking screws. Preferably, the first connecting holes 310 and the second connecting holes 320 are each provided as four, each first matching surface 21 has two first matching holes 210, and each second matching surface 22 has two second matching holes 220.

[0075] Specifically, referring to Figure 2 , still taking the connection between the joint part 20 at one end of the first frame 11 and the joint part 20 at one end of the third frame 13 as an example.

[0076] First, the first connecting member 31 is partially inserted into the first frame 11 through the third matching surface 23 at one end of the first frame 11, the two first connecting holes 310 on the first connecting surface 311 correspond to the two first matching holes 210 on the first matching surface 21 one by one, and then the two first locking members 51 are respectively threaded through the first matching holes 210 and screwed with the first connecting member 31.

[0077] Then, the second connecting member 32 is partially inserted into the first frame 11 through the third matching surface 23 at one end of the first frame 11, the two second connecting holes 320 on the second connecting surface 321 correspond to the two second matching holes 220 on the second matching surface 22 one by one, and then the two second locking members 52 are respectively threaded through the second matching holes 220 and screwed with the second connecting member 32.

[0078] Finally, the other part of the first connecting member 31 and the second connecting member 32 are sequentially inserted into the third frame 13, the remaining two first connecting holes 310 correspond to the two first matching holes 210 on the third frame 13 one by one, and the remaining two second connecting holes 320 correspond to the two second matching holes 220 on the third frame 13, and then the two first locking members 51 and the two second locking members 52 (i.e., four locking screws) are used for locking. Thus, the connection of the first frame 11 and the third frame 13 is completed.

[0079] In the present application, based on the design of the mating surface on each side frame end portion, the locking screws can be effectively prevented from contacting the adhesive layer 2, the locking screws are located on the inner frame surface and the mounting surface of the frame structure 1, and when the frame structure 1 is disassembled, the locking screws can be directly disassembled without being affected by the adhesive layer, thereby realizing the connection between the connecting piece and each side frame, and further realizing the disassembly of the frame structure 1. Subsequently, each independent side frame is separated from the adhesive layer or the touch screen 4.

[0080] The present application also provides a display module, referring to Figure 6 , comprising a touch screen 4, a display panel 3, an adhesive layer 2 and a frame structure 1 in any of the above embodiments arranged in sequence, the adhesive layer 2 is located between the touch screen 4 and the frame structure 1, and is used to bond the touch screen 4 and the frame structure 1.

[0081] In the present embodiment, the frame structure 1 and the touch screen 4 are bonded by frame bonding using the adhesive layer 2 (VHB glue, AB glue or a combination of the two). Based on the design of the splicing portion 20 of each frame in the above frame structure 1, during the insertion process of the display module, the frame structure 1 can be disassembled into relatively independent first side frame 11, second side frame 12, third side frame 13 and fourth side frame 14, and then each side frame is peeled off from the adhesive layer to realize the disassembly of the display module. This setting can effectively improve the disassembly efficiency of the display module, reduce manpower and production cost.

[0082] Specifically, the disassembly process of the display module specifically includes the following steps S10 to S740.

[0083] Step S10, referring to Figure 7 , the whole display module is placed on a heating platform 6 for heating. Preferably, the heating temperature of the heating platform 6 is set to 70℃.

[0084] In this step, the adhesive layer 2 (VHB glue, AB glue or a combination of the two) is heated for a certain period of time until the adhesive layer 2 gradually fails.

[0085] Step S20, referring to Figure 8 and Figure 8A , the locking screws at the connection of the frame structure 1 are disassembled in sequence. In this process, since the locking screws are located on the mounting surface and the inner frame surface of the frame structure 1 and are not in contact with the adhesive layer 2, they can be directly disassembled.

[0086] Step S30, after the locking screws are disassembled, the first connecting piece 31 is moved so that it is entirely placed in the first accommodating cavity 110 of the first side frame 11 and the second side frame 12. The second connecting piece 32 is moved so that it is entirely placed in the second accommodating cavity 120 of the first side frame 11 and the second side frame 12.

[0087] It should be noted that the role of this step is to achieve complete independence between the frames. In step S20, although the locking screw is disassembled, only the adjacent frames can be displaced in the length direction of the first connecting member 31 and the second connecting member 32. Since the two ends of the first connecting member 31 and the second connecting member 32 are respectively placed in the adjacent two frames, the adjacent frames cannot be displaced in other directions, and thus cannot be completely independent.

[0088] In step S40, the disassembly tool (crowbar 5) is connected with the support 41 in the disassembly assembly 40, and the independent frame and the adhesive layer are peeled off by using the lever principle.

[0089] In this step, for the sake of understanding, taking the viewing angle during the use of the display screen after the production of the display screen as an example, the first frame 11 can be understood as the top frame in this viewing angle, the second frame 12 can be understood as the bottom frame in this viewing angle, the third frame 13 can be understood as the left frame in this viewing angle, and the fourth frame 14 can be understood as the right frame in this viewing angle. The order of peeling off the frames is not limited.

[0090] In one embodiment, the top frame is peeled off first, then the left frame and the right frame are peeled off at the same time, and finally the bottom frame is peeled off.

[0091] Specifically, referring to Figure 9 , Figure 10 and Figure 10A , four crowbars 5 are connected with four supports 41 in four disassembly assemblies 40 on the top frame one by one, and then the crowbar 5 is moved by using the part connected with the support 41 as the fulcrum by manual or machine, the lever generates force to separate the top frame from the adhesive layer 2, until the top frame is peeled off.

[0092] Secondly, referring to Figure 11 , three crowbars 5 are connected with three supports 41 in three disassembly assemblies 40 on the left frame one by one, and then three crowbars 5 are connected with three supports 41 in three disassembly assemblies 40 on the right frame one by one, and then the crowbar 5 on the left frame and the right frame is moved in opposite directions by using the part connected with the support 41 as the fulcrum by manual or machine, to separate the left frame and the right frame from the adhesive layer.

[0093] Finally, referring to Figure 12 , four crowbars 5 are connected with four supports 41 in four disassembly assemblies 40 on the bottom frame one by one, and then the crowbar 5 is moved by using the part connected with the support 41 as the fulcrum by manual or machine, the lever generates force to separate the bottom frame from the adhesive layer. Thus, the separation of the frame structure 1 and the touch screen 4 is completed.

[0094] In this application, the terms "first", "second", "third", "fourth" are used only for descriptive purposes and not to be construed as indicating or implying relative importance. The terms "a number of", "several" mean two or more, unless otherwise indicated.

[0095] It is to be understood that the application is not limited to the precise construction already described and shown in the drawings, and that various modifications and changes can be made by those skilled in the art without departing from the scope of the application. The scope of the application is limited only by the claims that follow.
