[0014] This utility model proposes a contour-following double-sided adhesive 100.

[0015] Please see Figure 1 In one embodiment of this utility model, the contour-following double-sided adhesive 100 is applied to a curved display module. The curved display module includes a metal back plate 200 and a frame. The metal back plate 200 has a top edge 210, a left edge 220, and a right edge 230. The frame is used to assemble onto the metal back plate 200. The contour-following double-sided adhesive 100 includes an adhesive body 1. The adhesive body 1 is attached to the top edge 210, the left edge 220, and the right edge 230 of the metal back plate 200. The adhesive body 1 is used to prevent the frame from rubbing against the edges of the metal back plate 200 and to adhere to the foreign matter generated by the rubbing against the edges of the metal back plate 200.

[0016] In this technical solution, the contour-following double-sided adhesive 100 includes an adhesive body 1, which is attached to the top edge 210, left edge 220, and right edge 230 of the iron backplate 200. The shape and size of the adhesive body 1 match the edges of the iron backplate 200 to ensure that it can be tightly attached to the edges. The material of the adhesive body 1 has good adhesive properties. On the one hand, it can firmly adhere to the edges of the iron backplate 200. On the other hand, during the assembly of the adhesive frame, when the adhesive frame rubs against the edges of the iron backplate 200, it can effectively prevent the generation of foreign objects such as adhesive residue. Even if a small amount of foreign objects are generated, the adhesive body 1 can adhere to these foreign objects, preventing them from entering the module backlight area or falling into the visible area of ​​the product screen. This avoids problems such as module backlight defects caused by foreign objects and affects the appearance and performance of the product, thereby improving production efficiency and product quality.

[0017] Please see Figure 1 , Figure 4 and Figure 5In one embodiment, the adhesive body 1 includes a first adhesive segment 11 and two second adhesive segments 12. The first adhesive segment 11 is disposed corresponding to the top edge 210 of the iron back plate 200, and the two second adhesive segments 12 are disposed corresponding to the left edge 220 and the right edge 230 of the iron back plate 200, respectively. The adhesive body 1 includes a first adhesive segment 11 and two second adhesive segments 12. The first adhesive segment 11 is disposed corresponding to the top edge 210 of the iron back plate 200, and its shape and size match the top edge 210, so that it can be tightly attached to the top edge 210. Two second adhesive segments 12 are respectively provided corresponding to the left fold 220 and right fold 230 of the iron back plate 200. The shape and size of the second adhesive segments 12 also match the corresponding left fold 220 and right fold 230, thereby ensuring that they can be tightly attached to the corresponding folds. The left fold 220 and right fold 230 have the same shape and size, so the second adhesive segments 12 can be used for both the left fold 220 and right fold 230. In practical applications, the materials of the first adhesive segment 11 and the second adhesive segment 12 both have good adhesive properties. The first adhesive segment 11 can effectively prevent the adhesive frame from rubbing against the top fold 210 of the iron back plate 200 to generate foreign objects, and can also adhere to any small amount of foreign objects that may be generated. Similarly, the two second adhesive segments 12 can also prevent the adhesive frame from rubbing against the left fold 220 and right fold 230 of the iron back plate 200 to generate foreign objects, and can also adhere to any small amount of foreign objects that may be generated. Through this structural design, the contoured double-sided adhesive 100 can fully protect the folded edges of the iron backplate 200, avoiding problems such as module backlight defects caused by foreign objects generated during the assembly of the adhesive frame, as well as issues affecting the product's appearance and performance, thereby improving production efficiency and product quality.

[0018] Specifically, please refer to Figure 5 In one embodiment, the extension line of the first adhesive segment 11 is an arc. This arc design allows the first adhesive segment 11 to better adapt to the shape of the curved display module, especially on the curved surface of the top edge 210. The arc-shaped first adhesive segment 11 can more closely conform to the curved contour of the top edge 210, thereby more effectively preventing the frame from rubbing against the top edge 210 and generating foreign matter during the frame assembly process. Simultaneously, the arc-shaped first adhesive segment 11 can also better adhere to any small amount of foreign matter that may be generated, further improving the reliability of the module and product quality.

[0019] Please see Figure 4In one embodiment, the extension line of the second adhesive segment 12 is a straight line. This straight-line design allows the second adhesive segment 12 to better adapt to the straight contours of the left fold 220 and right fold 230 of the iron back plate 200. The straight-line shape of the second adhesive segment 12 can fit tightly against the straight portions of the left fold 220 and right fold 230, thereby effectively preventing the adhesive frame from rubbing against the left fold 220 and right fold 230 and generating foreign matter during the assembly process. At the same time, the straight-line shape of the second adhesive segment 12 can also better adhere to any small amount of foreign matter that may be generated, further improving the reliability of the module and the product quality.

[0020] Please see Figure 1 , Figure 3 and Figure 5 In one embodiment, the top edge 210 of the iron back plate 200 is provided with a plurality of first buckles 211 at intervals, and the first rubber segment 11 is provided with a plurality of first protrusions 111 at intervals. Each first protrusion 111 corresponds to and covers a first buckle 211. The top edge 210 of the iron back plate 200 is provided with a plurality of first buckles 211 at intervals. These first buckles 211 are used to fix the rubber frame during assembly to ensure the structural stability of the module. The first rubber segment 11 is provided with a groove at intervals corresponding to the top edge 210, and some of the first protrusions 111 are connected to the bottom wall of the groove so that the first rubber segment 11 can better adapt to the top edge 210. The first adhesive segment 11 has multiple first protrusions 111 spaced apart. Each first protrusion 111 corresponds to and covers a first buckle 211. This design allows the first adhesive segment 11 to not only adhere to the top edge 210 but also cover the first buckle 211, further preventing the adhesive frame from rubbing against the first buckle 211 and generating foreign objects. At the same time, the design of the first protrusions 111 can also better adhere to any small amount of foreign objects that may be generated, further improving the reliability of the module and the product quality.

[0021] Please see Figure 1 , Figure 2 and Figure 4In one embodiment, the left folded edge 220 and the right folded edge 230 of the iron back plate 200 are each provided with a plurality of slots 222 and a plurality of second buckles 221 at intervals. The second rubber segment 12 is provided with a plurality of notches 122 and a plurality of second protrusions 121 at intervals. Each notch 122 corresponds to a slot 222, and each second protrusion 121 corresponds to a second buckle 221 and covers the second buckle 221. The left folded edge 220 and the right folded edge 230 of the iron back plate 200 are each provided with a plurality of slots 222 and a plurality of second buckles 221 at intervals. These buckles and slots 222 are used to fix the rubber frame during assembly to ensure the structural stability of the module. The second adhesive segment 12 has multiple second protrusions 121 spaced apart. Each second protrusion 121 corresponds to and covers a second buckle 221. This design allows the second adhesive segment 12 to not only adhere to the left folded edge 220 and the right folded edge 230, but also to cover the second buckle 221, further preventing the adhesive frame from rubbing against the second buckle 221 and generating foreign objects. At the same time, the design of the second protrusions 121 can also better adhere to any small amount of foreign objects that may be generated, further improving the reliability of the module and the product quality. The second adhesive segment 12 has multiple notches 122 spaced apart, each notch 122 corresponding to a slot 222. This design allows the second adhesive segment 12 to avoid the slot 222 while adhering to the folded edge of the iron back plate 200, thus not affecting the normal use of the slot 222. The notch 122 design ensures that the second adhesive segment 12 will not interfere with the assembly of the slot 222 and the adhesive frame during the assembly process, and also avoids assembly problems caused by interference between the second adhesive segment 12 and the slot 222, further improving the reliability and efficiency of the assembly.

[0022] In one embodiment, the thickness of the adhesive body 1 is D, where 0.08mm ≤ D ≤ 0.12mm. The thickness range of the adhesive body 1 is carefully designed to meet the requirements of the assembly gap. If the thickness of the adhesive body 1 is less than 0.08mm, it may result in insufficient adhesion, failing to effectively prevent rubbing and friction between the adhesive frame and the iron back plate 200, and also failing to properly adhere to any foreign matter that may be generated. If the thickness of the adhesive body 1 is greater than 0.12mm, it may result in an excessively small gap during assembly, increasing the difficulty of assembly and potentially affecting the tight assembly of the adhesive frame and the iron back plate 200. Therefore, designing the thickness of the adhesive body 1 between 0.08mm and 0.12mm ensures both good adhesion and meets the requirements of the assembly gap, ensuring smooth assembly and improving production efficiency and product quality.

[0023] In one embodiment, the contoured double-sided adhesive 100 includes two release films, with each side of the adhesive body 1 adhered to one release film and positioned between the two release films. The contoured double-sided adhesive 100 also includes two release films, with each side of the adhesive body 1 adhered to one release film and positioned between the two release films, so that the adhesive body 1 is protected by the release films before use, preventing contamination or damage during storage and transportation. When in use, the release films can be easily removed, and the adhesive body 1 can be attached to the folded edge of the iron backing plate 200. The use of release films not only improves the protective performance of the adhesive body 1 but also facilitates assembly by operators, further improving production efficiency and product reliability.

[0024] In one embodiment, both ends of the adhesive body 1 are provided with tear handles. The tear handles make it easier for operators to attach the adhesive body 1 to the folded edge of the iron backing plate 200 during use. The tear handles facilitate the operator's gripping, which not only improves the convenience of operation but also reduces the risk of damage to the adhesive body 1 during assembly, further improving production efficiency and product reliability.

[0025] This utility model also proposes a curved display module, which includes a metal back plate 200, a frame, and a contoured double-sided adhesive 100. The specific structure of the contoured double-sided adhesive 100 is as described in the above embodiments. Since this curved display module adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. Among them, the metal back plate 200 has a top edge 210, a left edge 220, and a right edge 230; the frame is used to assemble on the metal back plate 200; the contoured double-sided adhesive 100 in any of the above embodiments has an adhesive body 1 attached to the top edge 210, the left edge 220, and the right edge 230 of the metal back plate 200. The adhesive body 1 is used to prevent the frame from rubbing against the edges of the metal back plate 200 and to adhere to the foreign matter generated by the rubbing against the edges of the metal back plate 200.

[0026] By adopting the above-mentioned design of contour double-sided adhesive 100, this curved display module can effectively prevent the rubber frame and the iron back plate 200 from rubbing against each other and generating foreign objects during the assembly process. At the same time, it can adhere to any small amount of foreign objects that may be generated, avoiding problems such as poor backlighting of the module and affecting the appearance and performance of the product caused by foreign objects. This design not only improves production efficiency, but also significantly improves the reliability and quality of the product.

[0027] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
