Description

Technical Field

[0001] This application belongs to the field of terminal technology, specifically relating to a display module and an electronic device. Background Technology

[0002] Typically, the screen assembly of an electronic device includes a touchscreen and a screen cover. The touchscreen is used to display content, while the screen cover protects it. When assembling the screen of an electronic device, the touchscreen is first glued to the back of the screen cover to form the screen assembly. Then, the back of the screen cover is glued to the support steps of the rear shell to fix the screen assembly to the rear shell, thus completing the screen assembly of the electronic device.

[0003] However, in order to ensure assembly reliability and waterproof sealing, the area where the back of the screen cover is bonded to the support step of the back shell is usually large. In order to bond the touch screen to the back of the screen cover, the size of the touch screen is usually set to be small. Therefore, it may result in a smaller area on the screen cover where the content can be displayed, resulting in a lower screen-to-body ratio of the electronic device. Utility Model Content

[0004] The purpose of this application is to provide a display module and electronic device that can solve the problem of low screen-to-body ratio in electronic devices.

[0005] In a first aspect, embodiments of this application propose a display module, comprising: a screen assembly including a screen cover and a touch screen component connected to a first side of the screen cover; a mid-frame surrounding a second side of the screen cover, the second side being adjacent to the first side; and a first adhesive component bonded between the second side and the inner wall of the mid-frame near the second side.

[0006] Secondly, embodiments of this application provide an electronic device including a display module as described in the first aspect.

[0007] In embodiments of this application, the display module may include a screen assembly, a mid-frame, and a first adhesive member. The screen assembly includes a screen cover and a touchscreen component. The touchscreen component is connected to a first surface of the screen cover. The mid-frame surrounds a second surface of the screen cover, which is adjacent to the first surface. The first adhesive member is bonded between the second surface and the inner wall of the mid-frame near the second surface. Because the first adhesive member is bonded between the second surface of the screen cover and the inner wall of the mid-frame near the second surface, the surface of the screen cover bonded to the inner wall of the frame (i.e., the second surface) is different from the surface connected to the touchscreen component (i.e., the first surface). Therefore, even if the area where the inner wall is bonded to the second surface is large, it will not affect the area of ​​the first surface of the screen cover where the touchscreen component can be bonded. Thus, the size of the touchscreen component can be set larger, thereby increasing the area of ​​the screen cover where content can be displayed while ensuring assembly reliability and waterproof sealing. In this way, when the display module is installed in an electronic device, the screen-to-body ratio of the electronic device can be increased while ensuring assembly reliability and waterproof sealing.

[0008] In embodiments of this application, the electronic device includes the aforementioned display module. Since the first adhesive component of the display module is bonded between the second surface of the screen cover of the display module's screen assembly and the inner wall of the display module's frame near the second surface, the surface of the screen cover bonded to the inner wall of the frame (i.e., the second surface) is different from the surface connected to the touchscreen component of the screen assembly (i.e., the first surface). Therefore, even if the area where the inner wall is bonded to the second surface is large, it will not affect the area of ​​the first surface of the screen cover where the touchscreen component can be bonded. Thus, the size of the touchscreen component can be set larger, thereby increasing the area of ​​the displayable content area on the screen cover while ensuring assembly reliability and waterproof sealing. In this way, the screen-to-body ratio of the electronic device can be increased while ensuring assembly reliability and waterproof sealing.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] The display module and electronic device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0034] In recent years, with the continuous development of smart electronic products, users' pursuit of screen-to-body ratio has been constantly increasing. For example, electronic devices such as watches, mobile phones, and tablets all have screen components. The size of the black border between the screen and the frame will give users different experiences. Currently, the industry is moving towards narrower black borders. Smaller black borders can bring users a larger screen-to-body ratio, a more refined appearance, and a wider touch experience. For a watch touchscreen of the same size, if the black border area is smaller, the actual display area will be larger.

[0035] Typically, the screen assembly of an electronic device includes a screen cover and a touchscreen component. The touchscreen component is used to display content, while the screen cover protects it. When assembling the screen of an electronic device, a front-side adhesive bonding process can be used. Specifically, the touchscreen component can first be bonded to the back of the screen cover to form the screen assembly. Then, adhesive is applied to the support steps of the rear shell, and the back of the screen cover is bonded to the support steps of the rear shell to fix the screen assembly to the rear shell, thereby completing the screen assembly of the electronic device. However, to ensure assembly reliability and waterproof sealing, the area where the back of the screen cover is bonded to the support step of the back shell is usually large. In addition, to avoid the influence of glue on the touch screen, a clearance space must be provided, which further reduces the area on the back of the screen cover where the touch screen can be installed. Thus, in order to bond the touch screen to the back of the screen cover, the size of the touch screen is usually set to be small, resulting in a large black border area on the screen cover. Therefore, the area on the screen cover where content can be displayed (such as the actual display area mentioned above) may be small, resulting in a low screen-to-body ratio of the electronic device.

[0036] However, in this embodiment, the display module may include a screen assembly, a mid-frame, and a first adhesive member. The screen assembly includes a screen cover and a touchscreen component. The touchscreen component is connected to a first surface of the screen cover, and the mid-frame surrounds a second surface of the screen cover, adjacent to the first surface. The first adhesive member is bonded between the second surface and the inner wall of the mid-frame near the second surface. Because the first adhesive member is bonded between the second surface of the screen cover and the inner wall of the mid-frame near the second surface, the surface of the screen cover bonded to the inner wall of the frame (i.e., the second surface) is different from the surface connected to the touchscreen component (i.e., the first surface). Therefore, even if the area where the inner wall is bonded to the second surface is large, it will not affect the area of ​​the first surface of the screen cover where the touchscreen component can be bonded. Thus, the size of the touchscreen component can be set larger, thereby increasing the area of ​​the screen cover where content can be displayed while ensuring assembly reliability and waterproof sealing. In this way, when the display module is installed in an electronic device, the screen-to-body ratio of the electronic device can be increased while ensuring assembly reliability and waterproof sealing.

[0037] Figures 1 to 15 A schematic diagram of the structure of a display module provided in an embodiment of this application is shown. Figure 1 As shown, the display module provided in this application embodiment may include: a screen assembly 100, which includes a screen cover 101 and a touch screen 102, the touch screen 102 being connected to a first surface 1011 of the screen cover 101; a middle frame 200, which surrounds a second surface 1012 of the screen cover 101, the second surface 1012 being adjacent to the first surface 1011; and a first adhesive member 300, which is bonded between the second surface 1012 and the inner wall 201 of the middle frame 200 near the second surface 1012.

[0038] In some embodiments of this application, the screen component 100 described above is used to display content.

[0039] In some embodiments of this application, the screen cover 101 can be a glass cover, but it can also be a cover made of other materials. This application does not limit this.

[0040] In some embodiments of this application, the touch screen component 102 may include a flexible printed circuit (FPC) module, which may include, but is not limited to, a circuit layer, a liquid crystal layer, etc. The touch screen FPC module can be used to display content and can convert the user's input on the screen component 100 into corresponding electrical signals.

[0041] It should be noted that for the description of the touch screen FPC module, please refer to the specific description in the relevant technology, and the embodiments of this application will not be repeated here.

[0042] In some embodiments of this application, the first surface 1011 can be understood as the side facing away from the user when the display module is in use. The user can view the content displayed on the touch screen 102 through the side of the screen cover 101 that is opposite to the first surface 1011.

[0043] It is understandable that if the touchscreen 102 is larger, the area of ​​the displayed content that the user can see through the side of the screen cover 101 opposite to the first surface 1011 will be larger. In other words, the actual display area of ​​the screen assembly 100 will be larger, and the black border area of ​​the screen assembly 100 will be smaller. Conversely, if the touchscreen 102 is smaller, the area of ​​the displayed content that the user can see through the side of the screen cover 101 opposite to the first surface 1011 will be smaller. In other words, the actual display area of ​​the screen assembly 100 will be smaller, and the black border area of ​​the screen assembly 100 will be larger.

[0044] In some embodiments of this application, the second surface 1012 of the screen cover 101 may be a surface adjacent to the first surface 1011 or at least two surfaces. It is understood that the first surface 1011 and the second surface 1012 are different surfaces.

[0045] In some embodiments of this application, the aforementioned middle frame 200 can be a metal middle frame. Of course, the middle frame 200 can also be made of other materials, and this application does not limit this.

[0046] In some embodiments of this application, such as Figure 2 As shown, the distance between the inner wall 201 of the middle frame 200 near the second surface 1012 and the second surface 1012 can be 0.05mm to 0.1mm. Of course, the distance between the inner wall 201 and the second surface 1012 can also be other values, and this application embodiment does not limit this.

[0047] In some embodiments of this application, the first adhesive 300 can be any of the following: glue, foam adhesive, etc. Of course, the first adhesive 300 can also be other adhesives, and this application does not limit the specific adhesive used.

[0048] In some embodiments of this application, the first adhesive 300 can be bonded between the second surface 1012 and the inner wall 201 by dispensing adhesive.

[0049] Of course, in order to further improve the sealing and waterproof performance of the display module, a waterproof layer can also be provided on the surface of the inner wall 201 and the second surface 1012, as illustrated below.

[0050] In some embodiments of this application, combined with Figure 1 ,like Figure 3 As shown, a laser-engraved layer 2011 is provided on the surface of the inner wall 201.

[0051] In this embodiment, since the laser engraving layer 2011 has the ability to improve the adhesion performance of the adhesive, the laser engraving layer 2011 is provided on the surface of the inner wall 201, which can improve the adhesion performance of the first adhesive 300 and improve the sealing and waterproof performance of the display module.

[0052] Thus, it can be seen that since a laser engraving layer can be set on the surface of the inner wall, the adhesion performance of the first adhesive can be effectively improved, so that the first adhesive can be tightly bonded between the second surface and the inner wall. Therefore, the sealing and waterproof performance of the display module can be further improved.

[0053] In some embodiments of this application, combined with Figure 1 ,like Figure 4 As shown, an ink layer 10121 is provided on the second surface 1012.

[0054] In some examples, an ink layer 10121 can be applied to the second surface 1012 by ink spraying.

[0055] In this embodiment, since the ink layer 10121 has waterproof capabilities, setting the ink layer 10121 on the second surface 1012 can further improve the sealing and waterproof performance of the display module.

[0056] Therefore, since an ink layer can be applied to the second surface, the sealing and waterproof performance of the display module can be further improved.

[0057] In some embodiments of this application, combined with Figure 1 ,like Figure 5 As shown, the display module provided in this application embodiment further includes: a support member 400, which is disposed on the inner wall 201 of the middle frame 200 near the second surface 1012, and the support member 400 is in contact with the first surface 1011; wherein, the first adhesive member 300 is bonded between the first surface 1011, the second surface 1012, the inner wall 201 and the support member 400.

[0058] In some examples, the aforementioned support member 400 is a support block, and the shape of the support block can be any of the following: cuboid, quadrilateral, cylinder, irregular shape, etc. The support block can be made of polyethylene terephthalate (PET), but of course, the support block can also be made of other materials, which are not limited in this application embodiment.

[0059] In some examples, the support 400 can be used to support the screen cover 101 and seal against water.

[0060] Understandably, on the one hand, when a user uses the display module, the user can input on the screen cover 101. At this time, the screen cover 101 is subjected to a force towards the touch screen 102. Therefore, a support member 400 can be provided to prevent relative movement between the screen cover 101 and the middle frame 200 when the user inputs on the screen cover 101. In other words, the support member 400 can be used to support the screen cover 101. On the other hand, the support member 400 can contact the first surface 1011 of the screen cover 101, which can prevent water from entering the display module through the gap between the inner wall 201 and the second surface 1012 of the middle frame 200. In other words, the support member 400 can also be used for sealing and waterproofing.

[0061] In some examples, combined Figure 2 The distance between the first end of the middle frame 200 and the support member 400 can be 0.6mm to 1mm. The first end of the middle frame 200 can be the end of the middle frame 200 away from the support member 400. Of course, the distance between the first end of the middle frame 200 and the support member 400 can also be other values. This application embodiment does not limit this.

[0062] It is understood that the waterproof path of the display module is from the first end of the middle frame 200 to the support member 400. Therefore, the distance between the first end of the middle frame 200 and the support member 400 can be set to 0.6mm to 1mm to ensure assembly reliability and waterproof sealing.

[0063] In this embodiment, the waterproof path of the display module is from the first end of the middle frame 200 to the support member 400. To ensure assembly reliability and waterproof sealing, the waterproof path can be set to be relatively long, for example, the length of the waterproof path (hereinafter referred to as the waterproof height) can be set to 0.6mm to 1mm. This allows for a larger area where the inner wall 201 of the middle frame 200 is bonded to the second surface 1012 of the screen cover 101. Furthermore, since the surface of the screen cover 101 bonded to the inner wall 201 (i.e., the second surface 1012) is different from the surface connected to the touchscreen 102 (i.e., the first surface 1011), even if the area where the inner wall 201 is bonded to the second surface 1012 of the screen cover 101 is large, it will not affect the area where the first surface 1011 of the screen cover 101 can bond to the touchscreen 102. Therefore, the size of the touchscreen 102 can be set to be larger. Furthermore, since assembly reliability and waterproof sealing can be ensured by making the area where the inner wall 201 is bonded to the second side 1012 of the screen cover 101 larger, the area where the support member 400 is bonded to the first side 1011 of the screen cover 101 can be smaller. For example, the area where the support member 400 is bonded to the first side 1011 of the screen cover 101 is smaller than the area where the back side (first side) of the screen cover is bonded to the support step of the back shell in the related art. This also achieves support for the back side of the screen cover. Therefore, the size of the touch screen component 102 can be set to be larger.

[0064] Thus, since a support member can be set in the display module, and this support member can contact the first surface, the first adhesive member can be bonded between the first surface, the second surface, the inner wall 201, and the support member. In this way, even if the area where the support member is bonded to the back of the screen cover is small, for example, smaller than the area where the back of the screen cover is bonded to the support step of the back shell in related technologies, the back of the screen cover can still be supported. This avoids relative movement between the screen assembly and the middle frame due to large input pressure from the user. Therefore, the size of the touch screen assembly can be set to be larger, thereby increasing the area of ​​the displayable content on the screen cover while ensuring assembly reliability. In this way, the screen ratio of the electronic device can be increased while ensuring assembly reliability and waterproof sealing.

[0065] In some embodiments of this application, combined with Figure 5 ,like Figure 6 As shown, a first protrusion 203 is also provided on the inner wall 201, which protrudes in the direction toward the touch screen 102; the support member 400 is provided on the first protrusion 203.

[0066] In some examples, the first protrusion 203 described above can be integrally formed with the middle frame 200.

[0067] In some examples, combined Figure 2 The distance between the first protrusion 203 and the touch screen 102 is greater than 0.35mm. It is understood that since the touch screen 102 may collide with the first protrusion 203 due to the movement of the display module, the distance between the first protrusion 203 and the touch screen 102 can be set to a value greater than 0.35mm. This can avoid the collision between the touch screen 102 and the first protrusion 203, thereby improving the durability of the touch screen 102.

[0068] Thus, since a first protrusion is provided on the inner wall and the support member is provided on the first protrusion, the support member's ability to support the screen cover can be increased, thereby further improving the assembly reliability of the display module.

[0069] In some examples, the height of the support member 400 in the direction away from the first protrusion 203 is greater than or equal to 0.1 mm and less than or equal to 0.2 mm.

[0070] Thus, since the height of the support member along the direction away from the first protrusion is greater than or equal to 0.1 mm and less than or equal to 0.2 mm, the support member's support capacity can be ensured while the height of the support member is small. Therefore, the internal space of the display module can be saved while ensuring the support capacity of the support member.

[0071] In some examples, combined Figure 6 ,like Figure 7 As shown, a laser-engraved layer 2031 is provided on the surface of the first protrusion 203.

[0072] In this embodiment, since the laser engraving layer 2031 has the ability to improve the adhesion performance of the adhesive, the laser engraving layer 2031 is provided on the surface of the first protrusion 203, which can improve the adhesion performance of the first adhesive 300 and improve the sealing and waterproof performance of the display module.

[0073] Thus, it can be seen that since a laser engraving layer can be set on the surface of the first protrusion, the adhesion performance of the first adhesive can be effectively improved, so that the first adhesive can be tightly bonded to the surface of the first protrusion and the second surface. Therefore, the sealing and waterproof performance of the display module can be further improved.

[0074] The following will illustrate the process of screen merging for the display module in an embodiment of this application.

[0075] like Figures 8 to 11As shown, the process of combining the display modules of this application embodiment may include the following steps:

[0076] Step 1: Perform plasma treatment on the inner wall 201 of the middle frame 200 to clean the surface of the inner wall 201, and then use a five-axis dispensing machine to apply adhesive (e.g., glue) to the inner wall 201 to form the first adhesive component 300. Figure 8 As shown;

[0077] Step 2: Perform plasma treatment on the second surface 1012 of the screen cover 101 to clean it, and use a screen joining device to center and join the screens so that the support member 400 contacts the first surface 1011 of the screen cover 101, and the first adhesive member 300 is attached between the first surface 1011, the second surface 1012, the inner wall 201, and the support member 400. At this time, the first adhesive member 300 (e.g., glue) is evenly pressed out and overflows, wherein the overflowing adhesive member is the overflow adhesive member 301, such as... Figure 9 As shown;

[0078] Step 3: After the screens are joined, due to the curing characteristics of the first adhesive component 300 (e.g., glue), it is necessary to wait 20-30 minutes for the first adhesive component 300 (e.g., glue) to cure. Then, use a scraping device or tool to scrape off the semi-cured glue, for example, to scrape off any excess glue on the outer adhesive component 301. Figure 10 As shown;

[0079] Step 4: After scraping off the adhesive, wait another 20-30 minutes. After 20-30 minutes, the smooth adhesive surface left from the previous scraping step will gradually harden, and the residual adhesive left on the side of the screen cover 101 and the middle frame 200 will also gradually harden. At this time, you can use alcohol to wipe off the adhesive residue on the surface, as shown below. Figure 11 As shown; the adhesive application is divided into two parts: rough application and fine application. Rough application mainly targets the curved positions 202 of the mid-frame 200 and 1013 of the screen cover 101, while fine application mainly focuses on the triangular area 1014.

[0080] Based on steps 1 to 4 above, the adhesive dispensing operation can be completed. This solution can simultaneously achieve three dimensions: sealing and waterproofing, ensuring strength and reliability, and guaranteeing a refined appearance. Furthermore, the operation process is simple and has significant cost advantages. The characteristic of this application lies in side dispensing, specifically dispensing adhesive between the inner wall 201 and the second surface 1012. Since side dispensing allows for various methods of cleaning up the adhesive, the solution presented in this application has been verified to achieve a relatively perfect adhesive path appearance.

[0081] Alternatively, a dry ice cleaning solution can be considered. Figure 12As shown, dry ice is used for cleaning within 20-30 minutes after applying the adhesive. Dry ice cleaning requires sealing the bottom of the screen assembly (e.g., touchscreen 102) to prevent moisture from entering the screen assembly, such as into touchscreen 102. Since the screen assembly itself can withstand extremely low temperatures, a short dry ice cleaning process will not damage the screen assembly.

[0082] This application provides a display module, which may include a screen assembly, a mid-frame, and a first adhesive member. The screen assembly includes a screen cover and a touchscreen component. The touchscreen component is connected to a first surface of the screen cover. The mid-frame surrounds a second surface of the screen cover, which is adjacent to the first surface. The first adhesive member is bonded between the second surface and the inner wall of the mid-frame near the second surface. Because the first adhesive member is bonded between the second surface of the screen cover and the inner wall of the mid-frame near the second surface, the surface of the screen cover bonded to the inner wall of the frame (i.e., the second surface) is different from the surface connected to the touchscreen component (i.e., the first surface). Therefore, even if the area where the inner wall is bonded to the second surface is large, it will not affect the area of ​​the first surface of the screen cover where the touchscreen component can be bonded. Thus, the size of the touchscreen component can be set larger, thereby increasing the area of ​​the screen cover where content can be displayed while ensuring assembly reliability and waterproof sealing. In this way, when the display module is installed in an electronic device, the screen-to-body ratio of the electronic device can be increased while ensuring assembly reliability and waterproof sealing.

[0083] Understandably, unlike related technologies, the screen cover 101 is not directly glued to the back cover, but rather directly glued to the mid-frame 200. The mid-frame 200 is no longer just an aesthetic component, but also a waterproofing element for the entire device. More importantly, the glue application between the screen cover 101 and the mid-frame 200 is located on the inner wall 201 of the mid-frame 200. The glue application width has been changed from the existing 1mm horizontal waterproof length to an improved side waterproof height. Waterproof sealing is achieved through this side application.

[0084] Furthermore, this application employs a side-side direct dispensing process, saving significant equipment and process costs. For example... Figure 13 As shown, the middle frame 200 is placed inside the five-axis dispensing machine. The middle frame 200 will rotate within the machine, and adhesive can be dispensed from the side. Due to the adhesiveness of the first bonding component 300 (e.g., glue), the glue will adhere to the inner wall 201 and will not fall off. This is very beneficial for subsequent screen assembly operations.

[0085] This application provides a structure and method for sealing and bonding a touchscreen and mid-frame using side-applied adhesive. It innovates the adhesive connection method between the touchscreen and mid-frame from three dimensions: structural design, adhesive properties, and process implementation. Unlike related technologies, this application applies adhesive (e.g., glue) to the inner wall 201 of the mid-frame 200, using the inner wall 201 and the second surface 1012 for adhesive bonding and waterproofing. This does not affect the planar space of the bottom touchscreen component 102, effectively reducing the black border of the screen assembly 100. Compared to related technologies, the side-applied adhesive solution effectively reduces the black border size, and the adhesive application is simple, efficient, and cost-effective, requiring only a conventional five-axis dispensing machine for side-applied adhesive application. It eliminates the need for complex vacuum injection molding, resulting in a significant cost advantage.

[0086] In some embodiments of this application, combined with Figure 1 ,like Figure 14 As shown, a receiving groove 204 is also provided on the inner wall 201, which is recessed in a direction away from the second surface 1012.

[0087] In some examples, the aforementioned receiving groove 204 can be a groove machined by a T-tool. Of course, the receiving groove 204 can also be other grooves, and this application embodiment does not limit this.

[0088] In some examples, the aforementioned receiving groove 204 is used to receive the first adhesive element 300.

[0089] In some examples, a laser-engraved layer is provided on the wall of the aforementioned receiving groove 204.

[0090] In this embodiment, since the laser engraving layer has the ability to improve the adhesion performance of the adhesive, setting the laser engraving layer on the groove wall of the receiving groove 204 can improve the adhesion performance of the first adhesive 300, thereby improving the sealing and waterproof performance of the display module.

[0091] Thus, since a receiving groove can be set on the inner wall, the volume of the first adhesive component between the inner wall and the second surface can be increased, thereby further increasing the assembly reliability and sealing and waterproof performance of the display module.

[0092] Furthermore, since the volume of the first adhesive component can be increased by setting a receiving groove on the inner wall, rather than by increasing the distance between the second surface and the inner wall, it can be ensured that the distance between the second surface and the inner wall does not increase, thus not affecting the refinement of the display module.

[0093] In some examples, combined Figure 2 The depth of the recess in the aforementioned receiving groove 204 is greater than 0.1 mm.

[0094] Optionally, the depth of the above-mentioned recess can be: the depth of the recess of the receiving groove 204 in the direction away from the second surface 1012.

[0095] Thus, since the depth of the recessed groove is greater than 0.1mm, it can be ensured that the groove can accommodate a large volume of the first adhesive component, thereby ensuring the assembly reliability and sealing and waterproof performance of the display module.

[0096] In some embodiments of this application, combined with Figure 1 ,like Figure 15 As shown, the display module provided in this application embodiment may further include: a housing 500, which is connected to the third surface 205 of the middle frame 200 away from the touch screen 102.

[0097] In some examples, the housing 500 may be made of plastic. Of course, the housing 500 may also be made of other materials, and this application embodiment does not limit this.

[0098] Thus, since the housing of the display module can be connected to the third side of the mid-frame away from the touch screen, water can be prevented from entering the interior of the display module from the third side of the mid-frame, thereby further improving the sealing and waterproof performance of the display module.

[0099] In some examples, combined Figure 15 The display module provided in this application embodiment may further include: a second adhesive 600, which is bonded between the third surface 205 and the housing 500.

[0100] Optionally, the second adhesive 600 can be any of the following: glue, foam adhesive, etc. Of course, the second adhesive 600 can also be other adhesives, which are not limited in this embodiment.

[0101] Thus, since the display module may also include a second adhesive component, and this second adhesive component is bonded between the third surface and the housing, the third surface and the housing can be tightly connected by the second adhesive component, thereby improving the sealing and waterproof performance of the display module.

[0102] Figure 16 A schematic diagram of the structure of an electronic device provided in an embodiment of this application is shown. Figure 16 As shown, the electronic device 600 provided in this application embodiment may include: the display module 601 in the above embodiment.

[0103] The electronic device in this application embodiment can be a terminal, or it can be any other device besides a terminal. For example, the electronic device can be a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. It can also be a server, network attached storage (NAS), personal computer (PC), television set (TV), ATM, or self-service machine, etc. This application embodiment does not specifically limit the scope of the electronic device.

[0104] This application provides an electronic device including the aforementioned display module. Since the first adhesive component of the display module is bonded between the second surface of the screen cover of the display module's screen assembly and the inner wall of the display module's frame near the second surface, the surface of the screen cover bonded to the inner wall of the frame (i.e., the second surface) is different from the surface connected to the touchscreen component of the screen assembly (i.e., the first surface). Therefore, even if the area where the inner wall is bonded to the second surface is large, it will not affect the area of ​​the first surface of the screen cover where the touchscreen component can be bonded. Thus, the size of the touchscreen component can be set larger, thereby increasing the area of ​​the displayable content area on the screen cover while ensuring assembly reliability and waterproof sealing. In this way, the screen-to-body ratio of the electronic device can be increased while ensuring assembly reliability and waterproof sealing.
