Detailed Implementation

[0044] As described in the background section, current display modules suffer from a problem of large bezel sizes.

[0045] To address the aforementioned technical problems, this application is proposed. This application provides a display module including a cover plate, a display panel, a mid-frame, and an adhesive layer; the display panel is located on one side of the cover plate; the mid-frame is located on the side of the display panel opposite to the cover plate; the adhesive layer is located between the cover plate and the mid-frame; wherein the orthographic projection of the cover plate onto the mid-frame covers the orthographic projections of the mid-frame and the adhesive layer onto the mid-frame. Thus, the bezel size of the display module is determined by the size of the cover plate, and the bezel size does not increase due to the mid-frame, thereby achieving a narrow bezel.

[0046] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods and means well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0048] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0049] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0050] Figure 1 The diagram shown is a structural schematic of a display module provided in one embodiment of this application. Figure 1 As shown, in a first aspect, embodiments of this application provide a display module 100, which includes a cover plate 110, a display panel 120, a mid-frame 130, and an adhesive layer 140. The display panel 120 is located on one side of the cover plate 110; the mid-frame 130 is located on the side of the display panel 120 opposite to the cover plate 110; and the adhesive layer 140 is located between the cover plate 110 and the mid-frame 130. The orthographic projection of the cover plate 110 onto the mid-frame 130 covers the orthographic projections of both the mid-frame 130 and the adhesive layer 140 onto the mid-frame 130. Thus, the bezel size of the display module is determined by the size of the cover plate, and the bezel size does not increase due to the mid-frame, thereby achieving a narrow bezel.

[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 reinforcing structure 131 that contacts the adhesive layer 140 and enhances the bond between the middle frame 130 and the adhesive layer 140.

[0053] By incorporating a reinforcing structure 131 within the mid-frame 130, the bonding strength between the mid-frame 130 and the adhesive layer 140 is enhanced, ensuring that the mid-frame 130 and the adhesive layer 140 will not separate or peel off during long-term use, thereby improving the overall durability and robustness of the display module 100. Furthermore, the strong bonding strength between the mid-frame 130 and the adhesive layer 140 ensures a secure bond, effectively preventing light leakage. It also effectively prevents separation of the mid-frame 130 and the adhesive layer 140 during collisions or impacts, improving the impact resistance of the display module 100. Moreover, the adhesive layer 140 effectively prevents external environmental factors such as dust and moisture from penetrating the interior of the display module 100, protecting internal electronic components from damage, thus enhancing the protective performance of the display module 100.

[0054] refer to Figure 1 The reinforcing structure 131 includes a limiting portion 1311; the middle frame 130 also includes a main body portion 132, with the limiting portion 1311 located on the side of the main body portion 132 near the display panel 120 and surrounding the display panel 120. The limiting portion 1311 and the main body portion 132 together form a second groove, which is recessed towards the side opposite to the display panel 120. In one embodiment, the orthographic projection of the display panel 120 onto the main body portion 132 is within the orthographic projection range of the second groove onto the main body portion 132.

[0055] This application provides an implementation of a reinforcing structure 131, which can be a limiting part 1311. The limiting part 1311 restricts at least a portion of the adhesive layer 140 to the inside of the limiting part 1311, thereby effectively reducing the risk of cracking of the adhesive layer 140 caused by adverse factors on the outside of the adhesive layer 140.

[0056] Preferably, in the cross-section along the thickness direction of the display panel 120, the outer edge of the limiting part 1311 and the outer edge of the cover plate 110 are collinear, thereby improving the appearance quality of the display module 100. Secondly, it improves the structural stability and strength of the display module 100, reduces stress concentration and deformation caused by misalignment or unevenness of the limiting part 1311 and the cover plate 110, and extends the service life of the display module 100. In addition, the adhesive layer 140 can effectively prevent external environmental factors such as dust and moisture from penetrating into the interior of the display module 100, improve the dustproof and waterproof performance of the display module 100, and protect the internal components from damage.

[0057] Figure 2The diagram shown is a structural schematic of a display module provided in another embodiment of this application. Figure 2 As shown, in the display module 100 provided in this application embodiment, preferably, the display module 100 further includes a support film 150 and a buffer layer 160 stacked on the side of the display panel 120 facing away from the cover plate 110. More preferably, the limiting portion 1311 surrounds the sidewall 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 robustness 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 strength 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 in thermal expansion coefficients between different materials, thereby reducing stress concentration between film layers and improving the stability and durability of the display module 100. In addition, the buffer layer 160 buffers and absorbs external impact forces, reducing the degree of damage to the display module 100 when subjected to external impacts and improving the impact resistance of the display module 100.

[0060] Figure 3 The diagram shown is a structural schematic of a display module provided in another embodiment of this application. Figure 3 As shown, in the display module 100 provided in this embodiment, the middle frame 130 includes a main body 132, and the reinforcing structure 131 includes a concave-convex surface 1312, which is located on the side of the main body 132 near the cover plate. For example, the concave-convex surface 1312 is disposed in the peripheral edge region of the main body 132.

[0061] This application provides another implementation of the reinforcing structure 131. The reinforcing 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 robustness of the display module 100.

[0062] Preferably, the uneven surface 1312 includes either a serrated surface or a textured surface.

[0063] Figure 4 The diagram shown is a structural schematic of a display module provided in another embodiment of this application. Figure 5 The diagram shown is a structural schematic of a display module provided in another embodiment of this application. Figure 4 and 5 As shown, in the cross-section along the thickness direction of the display panel 120, the outer edge of the adhesive layer 140 and the outer edge of the cover plate 110 are collinear.

[0064] The embodiments of this application improve the appearance quality of the display module 100; secondly, they improve the structural stability and strength of the display module 100, reduce stress concentration and deformation caused by misalignment or unevenness of the adhesive layer 140 and the cover plate 110, and extend the service life of the display module 100; in addition, they effectively prevent external environmental factors such as dust and moisture from entering the interior of the display module 100, improve the dustproof and waterproof performance of the display module 100, and protect the internal components from damage.

[0065] Preferably, the adhesive layer 140 includes a first adhesive portion 141 (see reference). Figure 4 and 5 In a cross-section along 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. 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 enhancing the visual experience.

[0066] The appearance can be consistent, meaning the color of the first adhesive part 141 and the cover plate 110 can be the same.

[0067] Preferably, the adhesive layer 140 further includes a second adhesive portion 142 (see reference). Figure 4 and 5 The second adhesive part 142 is located between the first adhesive part 141 and the display panel 120. The second adhesive part 142 is in contact with the cover plate 110. The material of the second adhesive part 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 adhesive portion 142 is small, it is not easy to fully fill the space by spraying the second adhesive portion 142 in one go. Therefore, the second adhesive portion 142 can be sprayed multiple times (e.g., two or three times) to fully fill the space.

[0069] Preferably, the adhesive layer 140 further includes a third adhesive portion 143 (see reference). Figure 4 The third adhesive part 143 is located between the first adhesive part 141 and the display panel 120, and is located on the side of the second adhesive part 142 near the middle frame 130. The third adhesive part 143 is in contact with the middle frame 130, and the material of the third adhesive part 143 is different from that of at least one of the first adhesive part 141 and the second adhesive part 142.

[0070] The third adhesive portion 143 is used to fill the gaps between the first adhesive portion 141, the second adhesive portion 142, the display panel 120, and the middle frame 130. Since the first adhesive portion 141, the second adhesive portion 142, and the third adhesive portion 143 have different functions, the third adhesive portion 143 is made of a different material than at least one of the first adhesive portion 141 and the second adhesive portion 142, thereby meeting the diverse needs 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. The distance between the orthographic projection of the boundary line of the display area AA and the non-display area ND onto 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. For example, this distance can be 0.2 mm, 0.4 mm, 0.6 mm, or 0.8 mm, etc.

[0072] Figure 6a The diagram shown is a structural schematic of a display module provided in another embodiment of this application. Figure 6b for Figure 6a The diagram shown is a partial top view of the display module. Figure 6a correspond Figure 6b Section line A1A2 in the middle. Figure 6b Only indicated Figure 6a The middle frame 130, adhesive layer 140, and antenna 170 are combined. Figure 6a and Figure 6b As shown, the display module 100 also includes an antenna 170, which contacts the adhesive layer 140 on the side of the display panel 120 away from the display area.

[0073] Since the adhesive layer 140 is a non-metallic material, it does not shield the antenna 170 signal, thus eliminating factors that could affect the antenna 170 signal (such as metallic materials). Furthermore, the antenna 170 can be positioned anywhere between the display panel 120 and the mid-frame 130, thereby expanding the antenna 170's placement area. Additionally, because the outer side of the antenna 170 is in contact with the adhesive layer 140, the adhesive layer 140 does not shield the antenna 170 signal. Compared to conventional solutions that require the use of nano-injection molding to fabricate the unshielded portion at the corresponding antenna 170 location, the former eliminates the need for nano-injection molding, thereby reducing production costs.

[0074] Figure 7a The diagram shown is a structural schematic of a display module provided in another embodiment of this application. Figure 7b for Figure 7a The diagram shown is a partial top view of the display module. Figure 7a correspond Figure 7b Section line A3A4 in the middle. Figure 7b Only indicated Figure 7a The middle frame 130, adhesive layer 140, and antenna 170 are combined. Figure 7a and Figure 7b As shown, preferably, the adhesive layer 140 has a fourth groove recessed on the side opposite to 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 recess recessed towards the side opposite to the display panel 120, and the antenna 170 is located within the fourth recess. In this case, the surface of the antenna 170 other than the surface near the display panel is covered by the adhesive layer 140.

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

[0077] Secondly, refer to Figures 6a-7b This application provides a display module 100, which includes a cover plate 110, a display panel 120, an antenna 170, a middle frame 130, and an adhesive 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 adhesive layer 140 is located between the cover plate 110 and the middle frame 130, and the adhesive layer 140 and the side of the antenna 170 away from the display panel 120 are in contact.

[0078] The display module 100 provided in this application embodiment uses an 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, it does not shield the antenna 170 signal, thereby eliminating the factors that would shield the antenna 170 signal (such as metallic materials). Furthermore, the antenna 170 can be positioned anywhere between the display panel 120 and the mid-frame 130, thus expanding the antenna 170's placement area. Additionally, since the outer side of the antenna 170 is in contact with the adhesive layer 140, the adhesive layer 140 does not shield the antenna 170 signal. Compared to conventional solutions where the frame needs to be fabricated using nano-injection molding at the corresponding antenna 170 location, the former eliminates the nano-injection molding process, thereby reducing production costs. 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, it improves the structural stability and strength of the display module 100, reduces stress concentration and deformation caused by 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, the adhesive layer 140 effectively prevents external environmental factors such as dust and moisture from entering the interior of the display module 100, improves the dustproof and waterproof performance of the display module 100, and protects the internal components from damage.

[0079] Thirdly, refer to Figure 4 and Figure 5This application provides a display module 100, which includes a cover plate 110, a display panel 120, a middle frame 130, and an adhesive 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 adhesive layer 140 is located between the cover plate 110 and the middle frame 130, and the adhesive layer 140 includes a plurality of adhesive portions, at least two of which are made of different materials.

[0080] by Figure 4 For example, the multiple 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 adhesive portion 143 is located between the first adhesive portion 141 and the display panel 120, and on the side of the second adhesive portion 142 near the middle frame 130, with the third adhesive portion 143 in contact with the middle frame 130. The first adhesive portion 141 and the cover plate 110 have the same appearance, thus improving the appearance quality of the display module 100 and enhancing the visual experience; the second adhesive portion 142 is a light-shielding portion, preventing light leakage at the edges of the display module 100; the third adhesive portion 143 fills the gaps between the first adhesive portion 141, the second adhesive portion 142, the display panel 120, and the middle frame 130. Since the first adhesive portion 141, the second adhesive portion 142, and the third adhesive portion 143 each have different functions, it is evident that by setting the adhesive layer into multiple adhesive portions, the diverse functional requirements of the adhesive layer 140 are met.

[0081] The structure of the display module 100 provided in this application has been described in detail above. The following describes the assembly method of the display module 100. It is understood that this assembly method corresponds to the structure of the display module 100; therefore, the structure mentioned in this assembly method can be referred to the above description of the display module 100, and will not be repeated here.

[0082] Figure 8 The diagram shown is a flowchart illustrating a method for assembling a display module according to an embodiment of this application. Figure 8 As shown in the figure, this application embodiment provides a method for assembling a display module, which includes the following steps.

[0083] Step S801: Attach the cover plate 110 to the display side of the display panel 120.

[0084] In step S802, a middle frame 130 is installed on the non-display side of the display panel 120, and the cover plate 110, the circumferential sidewall of the display panel 120 and the middle frame 130 form a first groove.
