[0038] The technical solution of this embodiment is to solve the above technical problems, and the general idea is as follows:

[0039] Embodiment 1

[0040] Reference appendix Figure 1 Figure 1 , the electronic device provided in this embodiment includes a frame body 1, a display panel 2, and a sealing portion 3. The frame body 1 includes a support plate 11, and the support plate 11 is provided with a first through hole 12 to communicate the first side and the second side of the support plate 1. The display panel 2 is fixed to the support plate 11, the display panel 2 is located on the first side of the support plate 11, the display panel 2 includes a flexible printed circuit 21 extending from a target edge of the display panel 2, the flexible printed circuit 21 passes through the first through hole 12, and a connection end 22 of the flexible printed circuit 21 is located on the second side of the support plate 11. The sealing portion 3 fills a gap between the flexible printed circuit 21 and an inner wall of the first through hole 12 to seal the first through hole 12.

[0041] It can be understood that, in order to solve the problem that the multi-layer structure of the main screen in the prior art and the step difference of different heights on the surface of the middle frame corresponding to the main screen result in poor sealing stability and potential leakage hazards, in the electronic device provided in this embodiment, a first through hole 12 is opened on the support plate 11 to provide a channel for the flexible printed circuit 21 and the connection end 22 of the display panel 2, so that the connection section 22 of the flexible printed circuit 21 can pass through the first through hole 12 to reach the second side of the support plate 11 to connect to the main board or other electronic components of the electronic device. Cooperatively, a sealing portion 3 is provided in the first through hole 12 to seal the first through hole 12, preventing water vapor on the first side of the support plate 11 from entering the second side of the support plate 11 through the first through hole 12 and affecting the main board or the electronic components connected to the connection end 22, and ensuring the sealing performance and the overall performance of the machine.

[0042] Among them, the electronic device provided in this embodiment can be, but is not limited to, devices with a display screen such as a mobile phone, a tablet computer, a monitor, a television, etc.

[0043] Among them, the frame body 1 is a rigid structure. The frame body 1 may include a closed annular frame 13 and an internal support plate 11. The shape of the closed annular frame 13 is not limited herein and can be designed and adjusted according to the shape of the electronic device. The closed annular frame 13 can be the side frame of the electronic device. The support plate 11 extends inward from the inner wall of the closed annular frame 13. The support plate 11 can cover all the areas enclosed by the closed annular frame 13 or only cover part of the areas enclosed by the closed annular frame 13. The support plate 11 can be a flat plate or a stepped plate, and can be designed and adjusted according to the actual component configuration inside the electronic device. In this embodiment, the support plate 11 can extend from the middle in the height direction of the closed annular frame 13 to divide the space in the height direction of the closed annular frame 13 into a first space on the first side of the support plate 13 and a second space on the second side of the support plate 13. The first space and the second space are relatively independent. The first space can be used to accommodate the display panel 2, and the second space can be used to accommodate components such as the main board, CPU, and GPU. A first through hole 12 is provided on the support plate 11. The shape and size of the first through hole 12 are not limited herein and can be designed and adjusted according to actual needs. For example: circular, rectangular, triangular, etc., as long as it can ensure that the wiring 21 and the connection end 22 of the display panel 2 can pass through. In this embodiment, the setting of the first through hole 12 enables the first space and the second space to communicate, and the connection end 22 of the display panel 2 can be connected to the main board or other components in the second space through the first through hole 12 to realize the power supply and display control of the display panel 2. The axial dimension of the first through hole 12 can be the same as the plate thickness of the first support plate 11. The first through hole 12 can also be a first through hole 12 with a larger axial dimension formed by extending a cylindrical structure on the first support plate 11, that is Figure 1 and Figure 2 the state shown to ensure the sealing effect of the seal 3.

[0044] Among them, the display panel 2 is a device in the electronic device for converting digital signals into visible images. The display panel 2 in this embodiment can be, but is not limited to, an LCD panel, an LED panel, an OLED panel, a mini LED panel, etc. The display panel 2 itself has waterproof properties in this embodiment. The display panel 2 is fixed to the first side of the support plate 11 parallel to the support plate 11, that is, placed in the first space, and can be connected by, but is not limited to, bonding or screwing; the target edge of the display panel 2 can be designed and selected according to actual needs. For example, the edge at the bottom end of the display panel 2, that is, the end facing the user when the user holds it; the flexible cable 21 is a flexible circuit board with circuits etched thereon, which can electrically connect the display panel 2 to the main board or other components to achieve the transmission of digital signals and display signals. In this embodiment, the shape and size of the flexible cable 21 can be designed and adjusted according to actual needs. For example, it can be designed as a cylindrical shape or a flat shape according to the shape of the first through hole 12. The connection end 22 is an electrical connection end, which can be, but is not limited to, a VGA (Video Graphics Array) interface, an HDMI (High-Definition Multimedia Interface) interface, a DVI (Digital Visual Interface) interface, a DisplayPort interface, a USB interface, etc.

[0045] Among them, the sealing part 3 is filled in the first through hole 12. The sealing part 3 can be a single structure or a combined structure. For example: a single colloid structure of silicone gel or liquid trough glue, wrapping the colloid on the flexible cable 21 and then stuffing it into the first through hole 12 to ensure complete fitting with the inner wall of the first through hole 12, and it can be sealed after curing and shaping; another example: a combined structure of a fixing structure and glue, positioning the flexible cable 21 in the first through hole 12, filling glue on the side of the fixing structure facing away from the first space. At this time, the glue can be liquid glue or gel, and it is cured and shaped in cooperation with the fixing structure and the first through hole 12 to achieve sealing. The sealing part 3 seals the first through hole 12 in the first through hole 12, thereby isolating the first space and the second space, and preventing water vapor outside the electronic device or in the first space from entering the second space through the first through hole 12 and affecting the main board or other components.

[0046] According to the above, the electronic device provided by the present application can specifically perform bonding to seal the first through hole 12 by providing the sealing part 3 in the first through hole 12, thereby sealing and isolating the first side and the second side of the support plate 11, preventing water vapor on the second side from entering the first side of the support plate 11 through the first through hole 21 and affecting the components on the first side or even the performance of the whole machine; thus solving the problem in the prior art that the multi-layer structure of the main screen and the step difference with different heights on the surface of the middle frame corresponding to the main screen result in poor sealing stability and potential leakage hazards.

[0047] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B, which is specifically understood as: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may exist.

[0048] Further, see Attachment Figure 1 In the electronic device provided in this embodiment, in a specific implementation, the sealing portion 3 includes a barrier 31 and a sealing 32; the barrier 31 is arranged in the first through hole 12, and the outer wall of the barrier 31 is in contact with the inner wall of the first through hole 12; the sealing 32 is arranged on the side of the barrier 31 away from the display panel 2, and the sealing 32 is sealed with the barrier 31 and the inner wall of the first through hole 12.

[0049] It is understandable that in order to ensure the sealing effect and prevent the flow of glue from affecting the sealing effect or even affecting other components, the sealing part 3 in this embodiment can be set to include a barrier 31 and a seal 32. The barrier 31 positions the cable 12 in the first through hole 12, and forms a groove-shaped space on the side of the first through hole 12 facing the second space to accommodate the seal 32, ensuring the capacity of the seal 32 and preventing the seal 32 from flowing into the first space; the barrier 31 can be a rigid structure or a deformable structure, for example: a rubber part, which can be compressed and inserted into the first through hole 12, and then expanded to ensure a close fit with the inner wall of the first through hole 12. The barrier 31 can be an annular structure, so that the cable 21 can pass through the barrier 31 for easy installation and positioning. The annular structure can be an integral structure or a split structure. Accordingly, the seal 32 can be a gel-like colloid or a liquid colloid. After the barrier 31 is set, the seal 32 can be glued in cooperation with the cable 21 to ensure that the inner wall of the seal 32 and the outer wall of the cable 21, and the outer wall of the seal 32 and the inner wall of the first through hole 12 are all in a sealed state. It can be understood that the position of the cable 21 in the first through hole 12 or the barrier 31 can be designed and adjusted according to actual needs. For example, it can be in the middle of the first through hole 12 to ensure that the circumferential outer wall of the cable 21 is wrapped by the barrier 31 and the seal 32; it can also be pressed and fitted on the inner wall of the first through hole 12 in cooperation with the barrier 31, and the cable 21 is kept in the middle of the first through hole 12 when the seal 32 is set later; it can also be in the form of the cable 21 always fitting on the inner wall of the first through hole 12.

[0050] Furthermore, in the electronic device provided in this embodiment, in a specific implementation, the size of the seal 32 along the first direction a is at least 1 / 2 of the size of the first through hole 12 in the first direction a; wherein the first direction a is the axial direction of the first through hole 12 .

[0051] It can be understood that in order to ensure the sealing effect of the seal 32 and avoid failure, the setting position of the barrier 31 in this embodiment is specially designed to ensure that there is enough space for the first through hole 12 on the side of the barrier 31 facing the second space, so that when the seal 32 is accommodated in the first through hole 12, its size is at least 1 / 2 of the axial size of the first through hole 12, so as to ensure that its sealing path is long enough, thereby ensuring the sealing effect.

[0052] Further, see Attachment Figure 2 The electronic device provided in this embodiment, in a specific implementation, further includes a second barrier 4; the second barrier 4 is arranged on the side of the sealing member 32 away from the barrier 31, and the outer wall of the second barrier 4 is in contact with the inner wall of the first through hole 12.

[0053] It is understandable that in order to ensure the service life of the seal 32 and prevent it from falling off, a second barrier 4 is provided in this embodiment. The second barrier 4 is provided on the side of the seal 32 away from the barrier 31. The second barrier 4 can be provided in the first through hole 12 or outside the first through hole 12, and can also be partially provided in the first through hole 12 and partially provided outside the first through hole 12, so as to block and seal the seal 32 and prevent it from falling off; as for the outer wall of the second barrier 4 in the first through hole 12, it fits with the inner wall of the first through hole 12, and can also play a certain sealing role again. The second barrier 4 can be a rigid structure or a deformable structure, and can be the same as or different from the barrier 31, for example: a blocking cover; the second barrier 4 can be a structural member or a colloid structure, for example: a blocking glue.

[0054] Furthermore, in the electronic device provided in this embodiment, the barrier 31 may be provided in at least the following forms:

[0055] In the first embodiment, the barrier member 31 comprises an annular member; the annular member is embedded in the first through hole 12 .

[0056] In this configuration, the barrier 31 can be a rigid structure or an elastic structure, for example, the barrier 31 can be a plastic part, whose size is adapted to the first through hole 12, and can be inserted along the axial direction of the first through hole 12, and keep the outer wall and the inner wall of the first through hole 12 in contact and fit, and can be interference fit or a small amount of fit; a through hole is opened on the barrier 31 to facilitate the passage of the cable 21. The barrier 31 can also be a rubber part, which can be inserted into the first through hole 12 by compression deformation, and after entering, it recovers its deformation and expands to keep a close fit with the inner wall of the first through hole 12.

[0057] The second type: refer to the attached Figure 3, the barrier member 31 includes a second through hole 33 and a first opening 34; the second through hole 33 is arranged along the axial direction of the barrier member 31, the first opening 34 is arranged on the outer wall of the axial direction of the barrier member 31, and the first opening 34 is communicated with the second through hole 33.

[0058] In this setting mode, the second through hole 33 is coaxial with the first through hole 12, and the first opening 34 provides a lateral channel for the cable 21 to enter the second through hole 33, ensuring the smooth positioning of the cable 21. For example: since the size of the through hole on the barrier member 31 is adapted to the size of the cable 21, when the radial dimension of the connection end 22 on the cable 21 is larger than the radial dimension of the cable 21, inserting the connection end 22 into the through hole on the barrier member 31 will encounter resistance. Therefore, in this embodiment, the first opening 34 is provided, and the connection end 22 can be placed at the other end of the axial direction of the barrier member 31 and then only the cable 22 is passed through the first opening 34 into the second through hole 33, which improves convenience and reduces the installation difficulty; the shape and size of the first opening 34 are not limited here and can be designed and adjusted according to the shape of the cable 21.

[0059] The third: the barrier member 31 has elasticity.

[0060] In this setting mode, a through hole is provided on the barrier member 31 for the cable 21 to pass through. With the elastic property, the barrier member 31 can be conveniently inserted into the first through hole 12, and can also ensure a state of being closely attached to the outer wall of the first through hole 12 under the action of the force of restoring deformation. During this process, the inner wall of the through hole on the barrier member 31 can also be closely attached to the outer wall of the cable 21, which helps to improve the sealing effect.

[0061] Furthermore, in the electronic device provided in this embodiment, in specific implementation, the barrier member 31 is an integrally formed structure.

[0062] It can be understood that, in order to ensure the strength and performance of the barrier member 31, the barrier member 31 can be set as an integrally formed structure in this embodiment. For any one of the above three setting modes, it can effectively improve the strength of the barrier member 31, effectively improve the plugging effect and service life when cooperating with the first through hole 12, and avoid the glue flow or glue leakage during the setting process of the sealing member 32.

[0063] Furthermore, referring to the appendix Figure 4 , in the electronic device provided in this embodiment, in specific implementation, it further includes a first back glue 5 and a second back glue 6; the first back glue 5 and the second back glue 6 are arranged at intervals along the circumferential direction of the display panel 2, and the display panel 2 is bonded to the support plate 11 through the first back glue 5 and the second back glue 6;

[0064] Among them, the sealing path from the first side to the second side of the support plate 11 does not include the area enclosed by the first back glue 5 and the second back glue 6 in the second direction b; the second direction b is parallel to the plate surface of the display panel 2.

[0065] It can be understood that: in order to realize the fixed connection between the display panel 2 and the support plate 11, the first back glue 5 and the second back glue 6 can be set in this embodiment. The forms of the first back glue 5 and the second back glue 6 are not limited here. They can be two U-shaped rubber strips arranged along the edge of the support plate 11, or a combination of a U-shaped rubber strip and a straight-shaped rubber strip. The first back glue 5 and the second back glue 6 can only be designed in a surrounding manner along the circumferential edge of the support plate 11, or additional rubber strips can be set at the position corresponding to the middle plate surface of the support plate 11, which is not limited in this embodiment. In this embodiment, the ends of the first back glue 5 and the second back glue 6 can be spaced apart or connected to each other, which does not affect the sealing path between the first space and the second space.

[0066] Embodiment 2

[0067] This embodiment provides a display screen, which includes a display panel 2, a flexible printed circuit (FPC) 21 and a protective member. The FPC 21 is electrically connected to the display panel 2 and has a connection end 22 away from the display panel 2; the protective member covers the FPC 21 between the display panel 2 and the connection end 22, and the protective member has a first form and a second form;

[0068] Among them, in the process of the protective member changing from the first form to the second form, it can be embedded into the through hole.

[0069] It can be understood that the protective member in this embodiment is the sealing member 3 described in Embodiment 1. For its structure and working principle, please refer to the detailed description of Embodiment 1, and no more details will be given here.
