[0030] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0031] The present disclosure provides a middle frame of a display device, comprising a side frame, an end frame and a connecting frame. A first bonding platform is arranged on the inner side of the side frame; the end frame is connected to one end of the side frame, and a second bonding platform is arranged on the inner side of the end frame; the connecting frame is respectively connected to the side frame and the end frame, and a glue injection hole is arranged on the connecting frame, and the glue injection hole passes through the connecting frame in the thickness direction of the display device.

[0032] In the present disclosure, an adhesive material (such as foam glue) is used on the first adhesive platform of the middle frame to bond the back plate of the screen to the middle frame, so as to strongly fix the screen and the middle frame, and then another adhesive material (such as caulking glue) is used on the second adhesive platform of the middle frame to bond the upper and lower edges of the screen cover to the middle frame, so as to form a seal between the upper and lower edges of the second adhesive platform and the screen cover. Finally, glue is poured between the first adhesive platform and the second adhesive platform from the glue injection hole opened on the connecting frame, and the two adhesive materials filled on the first adhesive platform and the second adhesive platform are joined to form a complete bonding and sealing of the screen and the middle frame, effectively achieving high-level waterproofing.

[0033] Display devices refer to devices equipped with a screen 4 that can output information through images, such as mobile phones, computer monitors, televisions, etc.

[0034] The middle frame refers to a structure in the display device that is used to mount the screen 4 and forms the circumferential contour of the display device. Generally speaking, the screen 4 is mounted on the middle frame and needs to be tightly bonded to the middle frame to achieve fixation and sealing to prevent the screen 4 from falling off or water from entering the display device.

[0035] Figure 1 is a middle frame of a display device according to an exemplary embodiment. Figure 2 yes Figure 1 The enlarged view of A in the middle is as follows: Figure 1 , Figure 2 As shown, the middle frame may include a side frame 1, an end frame 2 and a connecting frame 3. A first bonding platform 11 may be provided on the inner side of the side frame 1; the end frame 2 is connected to one end of the side frame 1, and a second bonding platform 21 may be provided on the inner side of the end frame 2; the connecting frame 3 connects the side frame 1 and the end frame 2 respectively, and the connecting frame 3 may be provided with a glue injection hole 31, which penetrates the connecting frame 3 in the thickness direction of the display device.

[0036] When the display device is in normal use, the side frames 1 are frames located on both sides, and the end frames 2 are frames located on the upper and lower ends. For example, the display device is a mobile phone, and the mobile phone has a receiver that is close to the user's ear and used to play sound when answering a call, and a microphone that is close to the user's mouth and used to receive sound when answering a call. The end frames 2 are the upper frame close to the receiver and the lower frame close to the microphone. In addition, the end frame 2 can refer to both the upper frame and the lower frame, or to one of the upper frame and the lower frame. The side frame 1 refers to the frames located on the left and right sides of the end frame 2, and the side frame 1 and the end frame 2 together form a continuous, closed middle frame.

[0037] In this embodiment, a first bonding platform 11 and a second bonding platform 21 for accommodating different adhesive materials are respectively provided in the side frame 1 and the end frame 2 of the middle frame. The screen 4 is strongly fixed by the adhesive material on the first bonding platform 11, and the upper and lower edges of the screen 4 are sealed by the adhesive material on the second bonding platform 21. Finally, glue is poured into the joint of the first bonding platform 11 and the second bonding platform 21 through the glue pouring holes 31 provided on the connecting frame 3. The adhesive materials on the first bonding platform 11 and the second bonding platform 21 are firmly and tightly bonded by glue pouring, thereby forming a complete closed sealing structure surrounding the middle frame, thereby achieving a high level of waterproofing of the joint gap between the middle frame and the screen 4.

[0038] In some embodiments, the number of glue holes 31 can be selected as needed. For example, glue holes 31 can be opened only on the connecting frames 3 on both sides of the upper frame, or glue holes 31 can be opened only on the connecting frames 3 on both sides of the lower frame, or glue holes 31 can be opened on the connecting frames 3 on both sides of the upper frame and the lower frame.

[0039] As an implementation of this embodiment, the middle frame includes a front surface for mounting the screen 4 , and the first bonding platform 11 is farther from the front surface than the second bonding platform 21 .

[0040] The front surface may refer to the side of the middle frame facing the user when the user reads information on the screen 4 after the middle frame is assembled into a display device. Specifically, it may refer to the plane surrounded by the edge of the middle frame close to the user, or it may refer to the direction in which the user is at this time.

[0041] The first bonding platform 11 is farther from the front surface than the second bonding platform 21, that is, the first bonding platform 11 and the second bonding platform 21 have a gradient in the thickness direction of the display device, and this gradient can match the thickness of the screen 4. When the screen 4 is installed on the middle frame, the back plate 41 of the screen 4 contacts the first bonding platform 11, and the cover plate 43 of the screen 4 contacts the second bonding platform 21. The back plate 41 has a large area for bonding, and adhesive materials such as foam glue can be used to tightly bond the screen 4, while the edge of the cover plate 43 is narrow, and the edge of the cover plate 43 of the screen 4 can be sealed with a caulking adhesive, which not only meets the stability of bonding, but also realizes the sealing of the edge of the cover plate 43.

[0042] The screen 4 is generally a multi-layer structure, and the part exposed to the outside after installation is called the cover plate 43, and the part located inside the middle frame and farthest from the cover plate 43 is the back plate 41. The edge of the cover plate 43 protrudes from the back plate 41, so when the screen 4 is installed in the middle frame, the back plate 41 can contact the first bonding platform 11, and the cover plate 43 can contact the second bonding platform 21.

[0043] In this embodiment, the first bonding platform 11 and the second bonding platform 21 are arranged in a gradient manner, so that the middle frame can be firmly bonded to the screen 4 through the first bonding platform 11, and can be sealed with the upper and lower edges of the screen 4 through the second bonding platform 21, thereby meeting the waterproof requirements while ensuring that the screen 4 is firmly installed.

[0044] In some instances, such as Figure 1 , Figure 2 As shown, the first bonding platform 11 extends from the side frame 1 to the connecting frame 3 , and the second bonding platform 21 extends from the end frame 2 to the connecting frame 3 . The first bonding platform 11 and the second bonding platform 21 at least partially overlap in the extending direction of the connecting frame 3 to form an overlapping portion 32 .

[0045] In some embodiments, the first bonding platform 11 extends from the side frame 1 to the connecting frame 3 and is connected to the connecting frame 3 ; the second bonding platform 21 extends from the end frame 2 to the connecting frame 3 and is connected to the connecting frame 3 .

[0046] In this embodiment, the first bonding platform 11 and the second bonding platform 21 are extended to the connecting frame 3 and partially overlapped, so that the adhesive material filled on the first bonding platform 11 and the second bonding platform 21 can partially overlap in the thickness direction of the display device, thereby enhancing the sealing and waterproof capabilities of the connecting frame 3.

[0047] At the same time, the first bonding platform 11 extends to the connection frame 3, and the screen 4 and the middle frame can be sealed without using a dispensing process at the connection frame 3, and no space needs to be reserved for dispensing at the connection frame 3, which effectively reduces the width of the connection frame 3. For example, the display device is a mobile phone, and the connection frame 3 is the rounded corner part of the mobile phone, which can effectively reduce the width of the middle frame at the rounded corner.

[0048] In some embodiments, the second bonding platform 21 can extend to the side frame 1 and be connected to the side frame 1; the second bonding platform 21 can also extend around the middle frame to form a closed structure for achieving complete circumferential contact with the screen 4 to enhance the sealing effect.

[0049] In some embodiments, Figure 1 , Figure 2 As shown, the glue injection hole 31 at least partially penetrates the overlapping portion 32 of the first bonding platform 11 , and the second bonding platform 21 partially blocks the glue injection hole 31 .

[0050] The second bonding platform 21 partially blocks the glue injection hole 31 , and it is not necessary for the second bonding platform 21 to be in contact with the edge of the glue injection hole 31 . It is only necessary to block the display device in the thickness direction.

[0051] In this embodiment, the glue injection hole 31 is set on the overlapping portion 32, and the glue injected from the glue injection hole 31 can complete the connection of the adhesive material on the first adhesive platform 11 and the second adhesive platform 21 without extending too much in the extension direction of the connecting frame 3, which can reduce the amount of glue injected in the glue injection hole 31 and enhance the connection strength of the glue injection to the adhesive material on the first adhesive platform 11 and the second adhesive platform 21. Even if the width of the end frame 2 is reduced to the same as that of the side frame 1, the waterproof requirement can still be met.

[0052] In some embodiments, the glue injection hole 31 penetrates the first bonding platform 11 and extends to the portion connected to the frame 3 , and the glue injection hole 31 is spaced apart from the edge of the first bonding platform 11 .

[0053] The adhesive material (such as foam glue) filled on the first bonding platform 11 will surround the glue filling hole 31 opened on the first bonding platform 11. In this way, the glue poured from the glue filling hole 31 will be surrounded by the adhesive material filled on the first bonding platform 11, and then isolated from the bonding part 42 (i.e., bonding in English, including the thin film transistor substrate and wiring used for COP) of the screen 4, thereby avoiding the glue poured into the glue filling hole 31 from directly contacting the bonding part 42 of the screen 4 and having an adverse effect on the bonding part 42.

[0054] In some embodiments, the side frame 1 includes a pair of side frames 1 arranged opposite to each other, and the end frame 2 is located at the bottom of the middle frame.

[0055] At this time, the end frame 2 refers only to the lower frame of the middle frame. The glue injection holes 31 are opened on the connecting frames 3 on both sides of the lower frame, so that the lower frame of the display device can be made as narrow as possible, and the upper frame uses a dispensing glue or a foam glue process on the back plate 41 to improve the bonding strength.

[0056] Figure 3 A display device is shown according to an exemplary embodiment. Figure 3 In the figure, the screen 4 is made transparent, and only the outline is shown; Figure 4 is a schematic diagram of a partial structure of a display device according to an exemplary embodiment. Figure 5 yes Figure 4 The enlarged view of B in the figure, and Figure 5 and Figure 4 The difference is, Figure 5 The figure shows the outline and shielding effect of the back plate 41 of the screen 4 by way of example, while the cover plate 43 of the screen 4 is ignored. Figure 6 yes Figure 3 The enlarged view of point C in the middle. Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the display device includes the middle frame of the present disclosure and a screen 4 with a multi-layer structure, the screen 4 includes a back plate 41 and a cover plate 43, the back plate 41 is the inner layer of the screen 4, and contacts the first bonding platform 11; the cover plate 43 is the outer layer of the screen 4, the edge of the cover plate 43 protrudes from the back plate 41, and the edge of the cover plate 43 contacts the second bonding platform 21. For ease of description, Figure 3 The screen 4 is made transparent and only the outline is shown.

[0057] The cover plate 43 is a layer that is exposed to the outside and directly faces the user after the screen 4 is installed on the middle frame, that is, the outermost layer; the back plate 41 is the innermost layer of the screen 4. After the screen 4 is installed on the middle frame, the back plate 41 is farthest from the user. The cover plate 43 can be transparent glass, plastic, etc. Generally, the cover plate 43 can be called cover glass or glass cover plate.

[0058] The first bonding platform 11 is connected to the back plate 41 of the screen 4, and the back plate 41 has a large space to bond with the first bonding platform 11, so that the screen 4 and the first bonding platform 11 can be tightly and firmly bonded. At the same time, the edge of the cover plate 43 is in contact with and connected to the second bonding platform 21, which can ensure that the edge of the screen 4 and the end frame 2 are strongly sealed when the end frame 2 is narrow.

[0059] like Figure 3 , Figure 5As shown, in some embodiments, the display device includes a first adhesive substance and a second adhesive substance, the first adhesive substance is filled between the first adhesive platform 11 and the back panel 41, and is used to bond the first adhesive platform 11 and the back panel 41; the second adhesive substance is filled between the second adhesive platform 21 and the edge of the cover panel 43, and is used to bond the second adhesive platform 21 and the edge of the cover panel 43; the fluidity of the second adhesive substance is greater than that of the first adhesive substance.

[0060] The first adhesive material is used to bond the back panel 41 of the screen 4 to the first bonding platform 11, and then the second adhesive material is filled between the second bonding platform 21 and the cover panel 43. The better fluidity of the second adhesive material ensures that it can enter the gap between the edge of the cover panel 43 and the second bonding platform 21 after the first adhesive material bonds the back panel 41 to the first bonding platform 11 to complete the bonding seal.

[0061] As an implementation of this embodiment, the first adhesive material may include one or more of foam adhesive, double-sided adhesive, silicone, and polyurethane adhesive. In the present disclosure, the second adhesive material is a caulking adhesive including one or more of shadowless adhesive, PUR hot melt adhesive, and epoxy structural adhesive.

[0062] The first adhesive material has strong viscosity and can achieve firm adhesion between the center frame and the screen 4. The second adhesive material has good fluidity and can directly enter the gap between the edge of the cover plate 43 and the second adhesive platform 21 to complete the adhesive sealing.

[0063] like Figure 5 As shown, in some embodiments, the display device includes a third adhesive material arranged on the connecting frame 3, the first adhesive material extends from the first adhesive platform 11 to the connecting frame 3 and contacts the third adhesive material, and the second adhesive material extends from the second adhesive platform 21 to the connecting frame 3 and contacts the third adhesive material.

[0064] The third adhesive material is poured into the glue injection hole 31 to bond and link the first adhesive material and the second adhesive material.

[0065] The first adhesive substance and the second adhesive substance are linked under the action of the third adhesive substance, and the first adhesive substance and the second adhesive substance are respectively bonded to the third adhesive substance. Thus, the first adhesive substance, the third adhesive substance, and the second adhesive substance can form a closed sealing ring layer to achieve a higher level of waterproof effect.

[0066] As an implementation method of this embodiment, the first adhesive material is arranged around the third adhesive material, and the third adhesive material is isolated from the bonding part 42 of the screen 4 by the first adhesive material, so as to prevent the third adhesive material entering from the glue injection hole 31 from affecting the bonding part 42. The first adhesive material can be a solid foam glue, which will not flow and diffuse, and will not affect the bonding part 42.

[0067] like Figure 4 As shown, in some embodiments, the screen 4 includes a bonding portion 42 (i.e., bonding in English, including a thin film transistor substrate and wiring for COP, etc.), and the bonding portion 42 extends from the back plate 41 toward the end frame 2 to avoid the setting of the glue injection hole 31.

[0068] The bonding part 42 has a certain width. If the bonding part 42 is not specially designed, the bonding part 42 will occupy most of the area inside the connecting frame 3, affecting the opening of the glue injection hole 31. Using laser cutting technology, the bonding part 42 is cut without affecting the function of the screen 4, and space is reserved for the glue injection hole 31. At the same time, space is also reserved for the first adhesive material to isolate the third adhesive material from the bonding part 42.

[0069] As an implementation method of this embodiment, Figure 3 , Figure 4 As shown, the bonding portion 42 is contracted from one end close to the back plate 41 to one end away from the back plate 41 , forming a structure for avoiding the glue injection hole 31 .

[0070] In this embodiment, the bonding portion 42 is gradually contracted from the back panel 41 to the lower end frame, thereby reducing the space occupied by the bonding portion 42 on the inner side of the connecting frame 3, thereby reserving space for the glue filling hole 31 and providing sufficient space for the first adhesive material to isolate the bonding portion 42 from the third adhesive material.

[0071] Figure 7 It is a schematic structural diagram of a display device according to an exemplary embodiment. The screen 4 includes a conductive area 44 arranged at the edge of the screen 4. The conductive area 44 is arranged on a side of the glue injection hole 31 away from the end frame 2.

[0072] For example, the display device is a mobile phone, and the conductive area 44 is arranged at the rounded corner of the edge of the screen 4 .

[0073] The conductive area 44 is a structure for releasing static electricity in the screen 4, and conducts the static electricity inside the screen 4 to the outside of the screen 4 to avoid static electricity from damaging the screen 4, while avoiding affecting the width of the foam glue, thereby ensuring the bonding effect.

[0074] The conductive area 44 generally uses silver paste as a conductive medium, and may also be made of other conductive materials.

[0075] The conductive area 44 is arranged on the side of the glue filling hole 31 away from the end frame 2. It will not affect the extremely narrow end frame 2, and will not be contaminated and wrapped by the third adhesive material poured into the glue filling hole 31 to affect the conductive performance, thereby ensuring electrostatic protection of the screen 4.

[0076] It is to be understood that in the present disclosure, "plurality" refers to two or more than two, and other quantifiers are similar. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. The singular forms "a", "the" and "the" are also intended to include plural forms, unless the context clearly indicates other meanings.

These terms are only used to distinguish the same type of information from each other, and do not indicate a specific order or degree of importance. In fact, the expressions "first", "second", etc. can be used interchangeably. For example, without departing from the scope of the present disclosure, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information.

[0078] It will be further understood that the terms “center”, “longitudinal”, “lateral”, “front”, “back”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

[0079] It can be further understood that, unless otherwise specified, “connection” includes a direct connection without other components between the two, and also includes an indirect connection with other components between the two.

[0080] It is further understood that, although the operations are described in a specific order in the drawings in the embodiments of the present disclosure, it should not be understood as requiring the operations to be performed in the specific order shown or in a serial order, or requiring the execution of all the operations shown to obtain the desired results.
