[0050] Figure 1 FIG. 1 is a schematic diagram of the structure of a display module provided by an embodiment of the present application. Figure 1 As shown, in the first aspect, the embodiment of the present application provides a display module 100, which includes a cover plate 110, a display panel 120, a middle frame 130 and a glue layer 140; the display panel 120 is located on one side of the cover plate 110; the middle frame 130 is located on the side of the display panel 120 away from the cover plate 110; the glue layer 140 is located between the cover plate 110 and the middle frame 130. Among them, the orthographic projection of the cover plate 110 on the middle frame 130 covers the orthographic projection of the middle frame 130 and the glue layer 140 on the middle frame 130. In this way, the frame size of the display module is determined by the cover plate size, and the frame size will not be increased due to the middle frame, thereby achieving a narrow frame.

[0051] In one embodiment, the cover plate 110 , the circumferential sidewalls of the display panel 120 , and the middle frame 130 enclose a first groove, and the adhesive layer 140 fills the first groove.

[0052] In one embodiment, the middle frame 130 includes a reinforcement structure 131 . The reinforcement structure 131 is in contact with the adhesive layer 140 . The reinforcement structure 131 is used to enhance the bonding force between the middle frame 130 and the adhesive layer 140 .

[0053] By providing the reinforcing structure 131 in the middle frame 130, the bonding force between the middle frame 130 and the adhesive layer 140 is enhanced, thereby ensuring that the middle frame 130 and the adhesive layer 140 will not separate or peel off during long-term use, thereby improving the overall durability and firmness of the display module 100. In addition, the strong bonding force between the middle frame 130 and the adhesive layer 140 allows the middle frame 130 and the adhesive layer 140 to be firmly bonded, thereby effectively preventing light leakage; at the same time, the separation of the middle frame 130 and the adhesive layer 140 when a collision or impact occurs during the use of the display module 100 is effectively prevented, thereby improving the impact resistance of the display module 100; and the adhesive layer 140 can effectively prevent external environmental factors such as dust and water vapor from invading the interior of the display module 100, protecting the internal electronic components from being damaged, that is, enhancing the protective performance of the display module 100.

[0054] refer to Figure 1 , the reinforcement structure 131 includes a limiting portion 1311; the middle frame 130 also includes a main body 132, the limiting portion 1311 is located on the side of the main body 132 close to the display panel 120, and surrounds the display panel 120. The limiting portion 1311 and the main body 132 are enclosed to form a second groove, and the second groove is recessed toward the side away from the display panel 120. In one embodiment, the orthographic projection of the display panel 120 on the main body 132 is located within the orthographic projection range of the second groove on the main body 132.

[0055] The embodiment of the present application provides an implementation method of a reinforcement structure 131. The reinforcement structure 131 may specifically be a limiting portion 1311. The limiting portion 1311 limits at least part of the adhesive layer 140 to the inner side of the limiting portion 1311, thereby effectively reducing the risk of the adhesive layer 140 cracking due to adverse factors on the outer side of the adhesive layer 140.

[0056] Preferably, in the cross section of the display panel 120 in the thickness direction, the outer edge of the limiting portion 1311 and the outer edge of the cover plate 110 are collinear, thereby improving the appearance quality of the display module 100; secondly, the structural stability and strength of the display module 100 are improved, and the stress concentration and deformation caused by the misalignment or unevenness of the limiting portion 1311 and the cover plate 110 are reduced, thereby extending the service life of the display module 100; in addition, the adhesive layer 140 can effectively prevent external environmental factors such as dust and water vapor from invading the interior of the display module 100, thereby improving the dustproof and waterproof performance of the display module 100, and protecting internal components from damage.

[0057] Figure 2FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present application. Figure 2 As shown, in the display module 100 provided in the embodiment of the present application, preferably, the display module 100 further includes a support film 150 and a buffer layer 160 stacked and arranged on the side of the display panel 120 away from the cover plate 110. Further preferably, the limiting portion 1311 surrounds the side wall of at least one of the support film 150 and the buffer layer 160.

[0058] The support film 150 is used to support and stabilize other components in the display module 100, ensuring the stability and firmness of the overall structure of the display module 100; at the same time, the support film 150 enhances the mechanical properties of the display module 100, such as bending resistance, tensile resistance and impact resistance, thereby improving the durability and reliability of the display module 100.

[0059] The buffer layer 160 reduces the stress caused by the mismatch of thermal expansion coefficients between different materials, thereby reducing the stress concentration between film layers and improving the stability and durability of the display module 100. In addition, the buffer layer 160 plays a role in buffering and absorbing external impact forces, reducing the degree of damage to the display module 100 when it is subjected to external impact, and improving the impact resistance of the display module 100.

[0060] Figure 3 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present application. Figure 3 As shown, in the display module 100 provided in the embodiment of the present application, the middle frame 130 includes a main body 132, and the reinforcement structure 131 includes a concave-convex surface 1312, which is located on the side of the main body 132 close to the cover plate. Exemplarily, the concave-convex surface 1312 is arranged at the peripheral edge area of ​​the main body 132.

[0061] The embodiment of the present application provides another implementation method of the reinforcement structure 131 . The reinforcement structure 131 may also include a concave-convex surface 1312 , thereby enhancing the bonding force between the middle frame 130 and the adhesive layer 140 , thereby improving the durability and firmness of the display module 100 .

[0062] Preferably, the concave-convex surface 1312 includes any one of a serrated surface and a textured surface.

[0063] Figure 4 Shown is a schematic structural diagram of a display module provided in another embodiment of the present application. Figure 5 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present application. Figure 4 and 5 As shown, in the cross section of the display panel 120 in the thickness direction, the outer edge of the glue layer 140 and the outer edge of the cover plate 110 are collinear.

[0064] The embodiment of the present application improves the appearance quality of the display module 100; secondly, it improves the structural stability and strength of the display module 100, reduces the stress concentration and deformation caused by the misalignment or unevenness of the adhesive layer 140 and the cover plate 110, and extends the service life of the display module 100; in addition, it effectively prevents external environmental factors such as dust and water vapor from invading the interior of the display module 100, improves the dustproof and waterproof performance of the display module 100, and protects internal components from damage.

[0065] Preferably, the adhesive layer 140 includes a first adhesive portion 141 (see Figure 4 and 5 ). In the cross section of the display panel in the thickness direction, the outer edge of the first adhesive portion 141 and the outer edge of the cover plate 110 are collinear. In one embodiment, the first adhesive portion 141 and the cover plate 110 have the same appearance, thereby improving the appearance quality of the display module 100 and improving the visual experience.

[0066] The consistent appearance may be that the color of the first adhesive portion 141 is consistent with the color of the cover plate 110 .

[0067] Preferably, the adhesive layer 140 further includes a second adhesive portion 142 (see Figure 4 and 5 ), the second glue portion 142 is located between the first glue portion 141 and the display panel 120, the second glue portion 142 contacts the cover plate 110, and the material of the second glue portion 142 is a light shielding material, thereby preventing light leakage from the edge of the display module 100.

[0068] It should be noted that, since the space for accommodating the second glue part 142 is small, it is not easy to fully fill the space by spraying the second glue part 142 once. Therefore, the second glue part 142 can be sprayed multiple times (for example, twice or three times) to fully fill the space.

[0069] Preferably, the adhesive layer 140 further includes a third adhesive portion 143 (see Figure 4 ), the third glue portion 143 is located between the first glue portion 141 and the display panel 120, and is located on the side of the second glue portion 142 close to the middle frame 130, the third glue portion 143 is in contact with the middle frame 130, and the third glue portion 143 and at least one of the first glue portion 141 and the second glue portion 142 are made of different materials.

[0070] The third adhesive part 143 is used to fill the gaps between the first adhesive part 141, the second adhesive part 142, the display panel 120 and the middle frame 130. Since the first adhesive part 141, the second adhesive part 142 and the third adhesive part 143 have different functions, the third adhesive part 143 and at least one of the first adhesive part 141 and the second adhesive part 142 are made of different materials, thereby meeting the diverse requirements of the adhesive layer 140.

[0071] Preferably, the display panel 120 includes a display area AA and a non-display area ND surrounding the display area AA, and the distance between the orthographic projection of the boundary line of the display area AA and the non-display area ND on the cover plate 110 and the outer edge of the cover plate 110 is greater than or equal to 0.2 mm and less than or equal to 0.8 mm. Exemplarily, the distance may be 0.2 mm, 0.4 mm, 0.6 mm, or 0.8 mm, etc.

[0072] Figure 6a Shown is a schematic structural diagram of a display module provided in another embodiment of the present application. Figure 6b for Figure 6a The diagram shows a partial top view of the structure of the display module. Figure 6a correspond Figure 6b Middle A1A2 section line. Figure 6b Only indicated Figure 6a The middle frame 130, the adhesive layer 140 and the antenna 170 are combined. Figure 6a and Figure 6b As shown, the display module 100 further includes an antenna 170 , and the antenna 170 is in contact with the adhesive layer 140 at a side away from the display area of ​​the display panel 120 .

[0073] Since the adhesive layer 140 is a non-metallic material, the adhesive layer 140 will not shield the antenna 170 signal, thereby eliminating the influencing factors (such as metal materials) that shield the antenna 170 signal, and the antenna 170 can be set at any position between the display panel 120 and the middle frame 130, thereby expanding the layout area of ​​the antenna 170; in addition, since the outer side of the antenna 170 is in contact with the adhesive layer 140, the adhesive layer 140 will not shield the antenna 170 signal. Compared with the conventional frame, which needs to use the nano injection molding process to prepare the non-shielding part at the corresponding antenna 170 position, the former eliminates the nano injection molding process, thereby reducing the production cost.

[0074] Figure 7a Shown is a schematic structural diagram of a display module provided in another embodiment of the present application. Figure 7b for Figure 7a The diagram shows a partial top view of the structure of the display module. Figure 7a correspond Figure 7b Middle A3A4 section line. Figure 7b Only indicated Figure 7a The middle frame 130, the adhesive layer 140 and the antenna 170 are combined. Figure 7a and Figure 7b As shown, preferably, the adhesive layer 140 has a fourth groove recessed toward a side away from the display panel 120 , and the antenna 170 is located in the fourth groove.

[0075] In one embodiment, the adhesive layer 140 has a fourth groove that is recessed toward the side away from the display panel 120 , and the antenna 170 is located in the fourth groove. In this case, all surfaces of the antenna 170 other than the surface close to the display panel are covered by the adhesive layer 140 .

[0076] refer to Figure 7a and Figure 7b Preferably, the middle frame 130 includes a third groove recessed toward a side away from the cover plate 110 , and the antenna 170 is located in the third groove.

[0077] Second, reference Figure 6a-Figure 7b An embodiment of the present application provides a display module 100, which includes a cover plate 110, a display panel 120, an antenna 170, a middle frame 130 and a glue layer 140; the display panel 120 is located on one side of the cover plate 110; the antenna 170 is located on the side of the display panel 120 away from the cover plate 110; the middle frame 130 is located on the side of the antenna 170 away from the cover plate 110, the glue layer 140 is located between the cover plate 110 and the middle frame 130, and the glue layer 140 is in contact with the side of the antenna 170 away from the display panel 120.

[0078] The display module 100 provided in the embodiment of the present application uses the adhesive layer 140 to cover the side of the antenna 170 away from the display area of ​​the display panel 120. Since the adhesive layer 140 is a non-metallic material, the adhesive layer 140 will not shield the antenna 170 signal, thereby eliminating the influencing factors (such as metal materials) that shield the antenna 170 signal, and the antenna 170 can be set at any position between the display panel 120 and the middle frame 130, thereby expanding the layout area of ​​the antenna 170; in addition, since the outer side of the antenna 170 is in contact with the adhesive layer 140, the adhesive layer 140 will not shield the antenna 170 signal. Compared with the solution that the conventional frame needs to use the nano injection molding process to prepare the non-shielding part at the corresponding antenna 170 position, the former eliminates the nano injection molding process, thereby reducing the production cost. On the other hand, the outer wall of the adhesive layer 140 is flush with the outer wall of the cover plate 110, thereby improving the appearance quality of the display module 100; secondly, the structural stability and strength of the display module 100 are improved, and the stress concentration and deformation caused by the misalignment or unevenness of the adhesive layer 140 and the cover plate 110 are reduced, thereby extending the service life of the display module 100; in addition, the adhesive layer 140 effectively prevents external environmental factors such as dust and water vapor from invading the interior of the display module 100, thereby improving the dustproof and waterproof performance of the display module 100 and protecting internal components from damage.

[0079] Thirdly, reference Figure 4 and Figure 5An embodiment of the present application provides a display module 100, which includes a cover plate 110, a display panel 120, a middle frame 130 and a glue layer 140; the display panel 120 is located on one side of the cover plate 110; the middle frame 130 is located on the side of the display panel 120 away from the cover plate 110; the glue layer 140 is located between the cover plate 110 and the middle frame 130, and the glue layer 140 includes a plurality of glue parts, and at least two of the glue parts are made of different materials.

[0080] by Figure 4 For example, the plurality of adhesive portions include a first adhesive portion 141, a second adhesive portion 142, and a third adhesive portion 143. In the thickness direction of the display panel, the outer edge of the first adhesive portion 141 and the outer edge of the cover plate 110 are collinear. The second adhesive portion 142 is located between the first adhesive portion 141 and the display panel 120, and the second adhesive portion 142 contacts the cover plate 110. The third glue part 143 is located between the first glue part 141 and the display panel 120, and is located on the side of the second glue part 142 close to the middle frame 130. The third glue part 143 contacts the middle frame 130. The first glue part 141 and the cover plate 110 have the same appearance, thereby improving the appearance quality of the display module 100 and improving the visual experience; the second glue part 142 is a light shielding part, thereby preventing light leakage from the edge of the display module 100; the third glue part 143 is used to fill the gap between the first glue part 141, the second glue part 142, the display panel 120 and the middle frame 130.
