Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] Foldable screen technology is now widely used in mobile phones and other electronic devices. Foldable screens can dynamically change the display size by bending to meet users' diverse needs for device size and display area.

[0003] In related technologies, due to the gap between the decorative frame and the foldable screen, dust can enter the interior of the device through the gap and come into contact with the foldable screen within the gap. The foldable screen has a multi-layered structure, which contains designed gaps and / or exposed areas. Dust entering the device may adhere to the designed gaps or exposed areas.

[0004] During the dynamic bending process of foldable screens, sand and dust in the design gaps can cause cracks or even breakage of the screen. Sand and dust in exposed areas can scratch the surface or even damage the wiring. As a result, electronic devices suffer from technical problems such as sand and dust easily damaging the foldable screen during folding, poor reliability of the foldable screen, and short service life. Summary of the Invention

[0005] This application aims to provide an electronic device that at least solves the technical problems of sand and dust easily damaging folding screens during folding, as well as the poor reliability and short service life of folding screens.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] This application provides an electronic device, which includes: a foldable screen assembly, the foldable screen assembly including multiple layers stacked together, the multiple layers including a screen protective layer, other layers stacked below the screen protective layer, at least one layer below the screen protective layer being recessed relative to the peripheral side of the screen protective layer to form a notch; and a first sealing member disposed on the peripheral side of the foldable screen assembly, the first sealing member sealing the notch.

[0008] The electronic device provided in this application includes a foldable screen assembly, which is formed by stacking multiple layers. Among the multiple layers is a screen protection layer, which is located on the top of the foldable screen assembly. The screen protection layer has sufficient rigidity and can provide shielding and protection for the other layers below it to prevent the remaining layers below from being damaged by external impact.

[0009] Specifically, in order to ensure the shielding and protection effect of the screen protective layer and to meet the display design requirements of the screen, at least one layer below the screen protective layer is recessed relative to the peripheral side of the screen protective layer to form a recessed notch below the screen protective layer. This notch is connected to the design gap between two adjacent layers below the screen protective layer, and in the case that the layers below are uneven, the surface of some layers will be exposed in the notch.

[0010] Building upon this, the electronic device also includes a first sealing component. This first sealing component is positioned at the notch on the periphery of the folding screen assembly, and after assembly, it covers the notch to create a seal. In this configuration, the first sealing component blocks sand and dust from the outside of the folding screen assembly, preventing it from entering the notch. This prevents sand and dust from entering the design gaps between adjacent layers and from adhering to exposed areas of the layers, ensuring the layers are not disturbed or damaged by sand and dust during dynamic bending. This solves the technical problems of sand and dust easily damaging the folding screen during folding, resulting in poor screen reliability and short lifespan. Ultimately, this achieves the technical effects of improving the sealing effectiveness of the folding screen assembly, increasing its reliability, reducing its failure rate, and extending its lifespan.

[0011] At the same time, the first sealing component can also prevent liquid from entering the gap, thereby reducing the possibility of short circuits and leakage faults in the foldable screen assembly, improving the waterproof rating of electronic devices, and thus achieving the technical effect of improving the practicality of electronic devices and optimizing the user experience.

[0025] The following is combined with Figures 1 to 6This application describes an electronic device according to an embodiment of the present application.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, according to some embodiments of this application, an electronic device 100 includes: a foldable screen assembly 110, the foldable screen assembly 110 including a plurality of stacked layers, the plurality of stacked layers including a screen protective layer 111, other stacked layers besides the screen protective layer 111 stacked below the screen protective layer 111, at least one stack below the screen protective layer 111 being recessed relative to the peripheral side of the screen protective layer 111 to form a notch 1102; and a first sealing member 120 disposed on the peripheral side of the foldable screen assembly 110, the first sealing member 120 sealing the notch 1102.

[0027] Figure 1 This is a schematic diagram of the structure of an electronic device 100 according to an embodiment of this application. Figure 1 The middle arrow c indicates the first direction of the foldable screen assembly 110.

[0028] Figure 2 This is a schematic diagram of the structure of an electronic device 100 according to an embodiment of this application. Figure 2 The middle arrow c indicates the first direction of the foldable screen assembly 110.

[0029] Figure 3 This is a schematic diagram of the structure of an electronic device 100 according to an embodiment of this application. Figure 3 The middle arrow c indicates the first direction of the foldable screen assembly 110.

[0030] This technical solution provides an electronic device 100, which includes a foldable screen assembly 110. The foldable screen assembly 110 can change its shape by dynamically bending, thereby changing its display area. Specifically, the foldable screen assembly 110 can reduce the size of the electronic device 100 by folding, making it easier for the user to hold. In this smaller size state, the display area is smaller, suitable for quickly viewing information. Correspondingly, the foldable screen assembly 110 can also increase the size of the electronic device 100 by unfolding, resulting in a larger display area suitable for reading, gaming, and watching videos.

[0031] The foldable screen assembly 110 is formed by stacking multiple layers, including a screen protection layer 111. The screen protection layer 111 is located at the top of the foldable screen assembly 110. The screen protection layer 111 has sufficient rigidity and can provide shielding and protection for the other layers below it to prevent the remaining layers below from being damaged by external impact.

[0032] Specifically, in order to ensure the shielding and protection effect of the screen protective layer 111 and to meet the display design requirements of the screen, at least one stacked layer below the screen protective layer 111 is recessed relative to the peripheral side of the screen protective layer 111 to form a recessed notch 1102 below the screen protective layer 111. The notch 1102 is connected to the design gap between two adjacent stacked layers below the screen protective layer 111, and when the stacked layers below are uneven, the surface of some stacked layers will be exposed in the notch 1102.

[0033] Based on this, the electronic device 100 also includes a first sealing component 120, which is disposed at the notch 1102 on the periphery of the folding screen assembly 110. After the assembly of the first sealing component 120 is completed, the first sealing component 120 can cover the notch 1102 to form a seal. In this case, the first sealing component 120 can block sand and dust from the outside of the folding screen assembly 110, preventing sand and dust from entering the notch 1102 on the periphery of the folding screen assembly 110. On the one hand, it prevents sand and dust from entering the design gap between two adjacent layers, and on the other hand, it prevents sand and dust from adhering to the exposed areas of the layers, so that the layers will not be disturbed or damaged by sand and dust during dynamic bending. This solves the technical problems of sand and dust easily damaging the folding screen during folding, resulting in poor reliability and short service life of the folding screen. Thus, it achieves the technical effects of improving the sealing effectiveness of the folding screen assembly 110, improving the reliability of the folding screen assembly 110, reducing the failure rate of the folding screen, and extending the service life of the folding screen.

[0034] At the same time, the first sealing component 120 that can provide to the notch 1102 can also prevent liquid from entering the notch 1102, thereby reducing the possibility of short circuit or leakage failure of the folding screen assembly 110, improving the waterproof rating of the electronic device 100, and thus achieving the technical effect of improving the practicality of the electronic device 100 and optimizing the user experience.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, optionally, the first sealing member 120 fills the notch 1102; the first sealing member 120 is disposed around the periphery of the folding screen assembly 110.

[0036] In this technical solution, the first sealing component 120 fills the gap 1102 on the periphery of the foldable screen assembly 110. By setting the first sealing component 120 to fill the gap 1102, the first sealing component 120 can occupy the space inside the gap 1102, eliminating the possibility of dust entering the gap, thereby improving the sealing effectiveness of the first sealing component 120 on the gap 1102.

[0037] Meanwhile, compared with the sealing scheme in which the first sealing component 120 leaves a margin inside the notch 1102, the first sealing component 120 that fills the notch 1102 has a higher fit and stronger positioning reliability. Even if the foldable screen assembly 110 is frequently bent, it will not be misaligned due to the margin in the notch 1102, thereby achieving the technical effect of improving the sealing reliability of the first sealing component 120.

[0038] Based on this, after the first sealing component 120 is installed on the folding screen assembly 110, the first sealing component 120 surrounds the folding screen. By setting the surrounding first sealing component 120, the folding screen assembly 110 can be sealed in all directions, avoiding sealing dead corners in the gaps 1102 around the folding screen, thereby reducing the possibility of sand and dust entering the inside of the folding screen assembly 110 and achieving the technical effect of improving the sealing effectiveness and reliability of the gaps 1102.

[0039] Specifically, adhesive can be injected around the foldable screen assembly 110 using a low-temperature injection process. After the adhesive cures at a low temperature, the first sealing component 120 is integrally formed. This low-temperature injection process can reduce the process complexity and assembly complexity of the electronic device 100, which is beneficial to reducing the production cost of the electronic device 100.

[0040] like Figure 1 As shown, in some embodiments, optionally, the stack also includes a support plate 112, the support plate 112 and the screen protective layer 111 being spaced apart; the peripheral side of the support plate 112 is at least partially recessed relative to the peripheral side of the screen protective layer 111, the recessed distance being a first distance ( Figure 1 Medium dimension a); wherein the range of the first distance is: greater than or equal to 0.15mm and less than or equal to 0.2mm.

[0041] In this technical solution, the stack also includes a support plate 112, which is disposed below the screen protective layer 111. The support plate 112 and the screen protective layer 111 are spaced apart, and multiple other stacks are stacked between the support plate 112 and the screen protective layer 111. The support plate 112 can provide effective support for the stack between the screen protective layer 111 and the support plate 112, reducing the possibility of irreversible deformation, stack collapse, and stack misalignment of the stack, thereby achieving the technical effect of improving the structural stability of the foldable screen assembly 110 and reducing the failure rate of the foldable screen assembly 110.

[0042] The screen protector 111 faces the outer side of the electronic device 100, and is the structure directly observed by the user during use. Specifically, the information to be displayed can be seen through the screen protector 111. The support plate 112 faces the inner side of the electronic device 100. The support plate 112 works with the frame 140 to position the folding screen assembly 110, ensuring that the folding screen is in the predetermined installation position.

[0043] Based on this, the peripheral side of the support plate 112 is recessed relative to the peripheral side of the screen protective layer 111. By setting the recessed support plate 112, a notch 1102 can be formed around the support plate 112. After the first sealing component 120 is formed, the first sealing component 120 can wrap around the support plate 112, thereby improving the positioning stability of the support plate 112 and the structural stability of the folding screen assembly 110. Furthermore, the wrapping first sealing component 120 has a better sealing effect on the notch 1102, which can further reduce the possibility of sand and dust entering the notch 1102, thereby improving the reliability of the folding screen assembly 110 and extending the service life of the folding screen assembly 110.

[0044] Specifically, the inward distance between the peripheral side of the first sealing component 120 and the peripheral side of the screen protective layer 111 is the first distance. In the circumferential direction of the folding screen assembly 110, different angles can correspond to different first distances, and different angles can also correspond to the same first distance.

[0045] Specifically, the first distance must be greater than or equal to 0.15 mm and less than or equal to 0.2 mm. By limiting the first distance to greater than or equal to 0.15 mm, the wrapping effect of the first sealing component 120 on the support plate 112 and the sealing effect of the first sealing component 120 on the notch 1102 can be guaranteed, preventing the overly thin first sealing component 120 from irreversibly flipping outward. By limiting the first distance to less than or equal to 0.2 mm, the supporting effect of the support plate 112 on the stack between the screen protective layer 111 and the support plate 112 can be guaranteed, preventing the outer ring of the stack from collapsing due to excessive inward shrinkage of the support plate 112.

[0046] Specifically, on the periphery of the first flat section 1104 and the periphery of the second flat section 1106, the periphery of the support plate 112 needs to be recessed relative to the periphery of the screen protective layer 111 to allow the adhesive to flow away from the screen protective layer 111, forming the second sealing component 130. On the periphery of the bending section 1108, the periphery of the support plate 112 can be flush with the periphery of the screen protective layer 111, thereby forming a full-enclosed seal on the upper and lower sides of the first flat section 1104 and the second flat section 1106, and a semi-enclosed seal on the upper side of the bending section 1108, so as to prevent the second sealing component 130 from affecting the dynamic bending action of the folding screen assembly 110.

[0047] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, optionally, the foldable screen assembly 110 is foldable in a first direction; the stack also includes a display layer 113; in the first direction of the foldable screen assembly 110, the display layer 113 includes a first end and a second end, the first end of the display layer 113 is located between the screen protective layer 111 and the support plate 112, and the second end of the display layer 113 is wrapped around to the side of the support plate 112 away from the screen protective layer 111.

[0048] The foldable screen component 110 can be dynamically bent in the first direction to achieve folding and unfolding actions, thereby changing the size of the foldable screen component 110 in the first direction and correspondingly changing the size of the display area.

[0049] Based on this, the foldable screen assembly 110 also includes a display layer 113, which can display corresponding information when a specified electrical signal is applied. Specifically, in a first direction of the foldable screen assembly 110, the first end of the display layer 113 is located between the screen protective layer 111 and the support plate 112, and the first end of the display layer 113 is recessed relative to the peripheral side of the screen protective layer 111 to form a partial notch 1102. After the first sealing member 120 is formed, the first sealing member 120 covers the first end of the display layer 113.

[0050] The second end of the display layer 113 is an electrical connection section 1136, extending to the side of the support plate 112 away from the screen protective layer 111, to facilitate the connection of the display layer 113 to the electrical control structure below the support plate 112. The second end of the display layer 113 extends below the support plate 112 via a bending section 1134, which wraps around the outer side of the layer below the display layer 113. The outer surface of the bending section 1134 is recessed relative to the peripheral side of the screen protective layer 111, forming a partial notch 1102. After the first sealing member 120 is formed, it wraps around the outer side of the bending section 1134.

[0051] Therefore, by limiting the inward retraction of the first end and the bending section 1134, the shielding and sealing effect of the first sealing component 120 on the display layer 113 can be guaranteed, preventing sand and gravel from contacting the surface of the display layer 113, reducing the possibility of damage to the display layer 113 during dynamic bending, thereby reducing the failure rate of the display layer 113 and extending the service life of the display layer 113.

[0052] like Figure 1 As shown, in some embodiments, optionally, the inward distance of the first end of the display layer 113 relative to the peripheral side surface of the support plate 112 is a second distance ( Figure 1 Medium dimension b); wherein the range of the second distance is: greater than or equal to 0 mm and less than or equal to 0.2 mm.

[0053] In this technical solution, the inward distance between the first end of the display layer 113 and the peripheral side of the support plate 112 is the second distance. The second distance must be greater than or equal to 0 mm and less than or equal to 0.2 mm.

[0054] The peripheral side of the support plate 112 is recessed relative to the peripheral side of the screen protective layer 111. In this case, by limiting the second distance to be greater than or equal to 0 mm, the sealing effect of the first sealing component 120 on the first end of the display layer 113 can be guaranteed. When the second distance is equal to 0, the first end of the display layer 113 is flush with the peripheral side of the support plate 112. The first sealing component 120 can be used to wrap the display layer 113 and the support plate 112 by single low-temperature injection molding using a precision mold.

[0055] By limiting the second distance to less than or equal to 0.2mm, the size of the black border on the foldable screen component 110 can be reduced, thereby increasing the display ratio of the foldable screen component 110, and thus improving the display effect of the foldable screen component 110 and enhancing the user experience.

[0056] like Figure 1 As shown, in some embodiments, optionally, in a first direction of the foldable screen assembly 110, the display layer 113 includes a display segment 1132, a bending segment 1134, and an electrical connection segment 1136. The display segment 1132 is located between the screen protective layer 111 and the support plate 112, the electrical connection segment 1136 is located on the side of the support plate 112 away from the screen protective layer 111, and the bending segment 1134 connects the display segment 1132 and the electrical connection segment 1136. The outer surface of the bending segment 1134 is recessed relative to the peripheral side of the screen protective layer 111. A first sealing member 120 is wrapped around the outside of the bending segment 1134.

[0057] In this technical solution, the display layer 113 is divided into a display segment 1132, a bending segment 1134, and an electrical connection segment 1136 according to their location. The display segment 1132 is located above the support plate 112 and is used to display the graphic information required by the user. The first end of the display layer 113 is located at the display segment 1132. The first end of the bending segment 1134 is connected to the display segment 1132. The bending segment 1134 is located outside the support plate 112 and bends downwards towards the support plate 112. The electrical connection segment 1136 is located below the support plate 112 and is used to connect the electrical control structure. The second end of the bending segment 1134 is connected to the electrical connection segment 1136, and the second end of the display layer 113 is located at the electrical connection segment 1136. By dividing the display section 1132, the bending section 1134, and the electrical connection section 1136, the wiring requirements of the display layer 113 can be met without affecting the dynamic bending action of the display section 1132.

[0058] Based on this, the bent section 1134 wraps around the outside of the stack below the display layer 113, and the outer surface of the bent section 1134 is recessed relative to the peripheral side of the screen protective layer 111 to form a partial notch 1102. After the first sealing member 120 is formed, the first sealing member 120 wraps around the outside of the bent section 1134.

[0059] By limiting the inward retraction of the bending section 1134, the sealing effect of the first sealing component 120 on the bending section 1134 can be guaranteed, preventing sand and gravel from contacting the outer surface of the bending section 1134 and preventing sand and gravel from damaging the circuits in the bending section 1134. This reduces the possibility of damage to the display layer 113 during dynamic bending, thereby reducing the failure rate of the display layer 113 and extending its service life.

[0060] like Figure 1 As shown, in some embodiments, the electronic device 100 may optionally include: a second sealing component 130 connected to the first sealing component 120, the second sealing component 130 being located on the side of the folding screen assembly 110 away from the screen protective layer 111; wherein the first sealing component 120 and the second sealing component 130 are integral structures formed by injection molding.

[0061] In this technical solution, the electronic device 100 further includes a second sealing component 130. The second sealing component 130 is located on the side of the folding screen assembly 110 away from the screen protective layer 111. On the side where the first end of the display layer 113 is located, the second sealing component 130 is located below the support plate 112. On the side where the bending section 1134 is located, the second sealing component 130 is located below the bending section 1134. By setting the second sealing component 130, a wrap-around seal can be formed on the side of the folding screen assembly 110 away from the screen protective layer 111, thereby strengthening the sealing effect of the folding screen assembly 110 in conjunction with the first sealing component 120 around the folding screen assembly 110, thereby extending the service life of the folding screen assembly 110 and improving the waterproof rating of the folding screen assembly 110.

[0062] The second sealing component 130 is connected to the first sealing component 120 in the notch 1102. Specifically, the first sealing component 120 and the second sealing component 130 can be integrally formed by a low-temperature injection molding process, thereby reducing the process complexity and assembly complexity of the first sealing component 120 and the second sealing component 130, and reducing the production cost of the electronic device 100.

[0063] Specifically, during the low-temperature injection molding process, the foldable screen assembly 110 is placed in a mold, with the inner ring surface of the mold flush with the peripheral side surface of the screen protective layer 111. By limiting the peripheral side surface of the support plate 112 to be recessed relative to the peripheral side surface of the screen protective layer 111, an adhesive channel can be formed between the peripheral side of the support plate 112 and the inner ring surface of the mold, allowing the injected adhesive to flow on both the upper and lower sides of the support plate 112, thus facilitating the integral molding of the first sealing component 120 and the second sealing component 130. Similarly, by limiting the outer surface of the bending section 1134 to be recessed relative to the peripheral side surface of the screen protective layer 111, an adhesive channel can be formed between the outer surface of the bending section 1134 and the inner ring surface of the mold, allowing the injected adhesive to flow on both the upper and lower sides of the bending section 1134, thus facilitating the integral molding of the first sealing component 120 and the second sealing component 130.

[0064] Specifically, the first sealing component 120 and the second sealing component 130 need to be molded using an adhesive with good elasticity and strong filling properties.

[0065] like Figure 1 As shown, in some embodiments, optionally, the foldable screen assembly 110 can be folded in a first direction; in the first direction of the foldable screen assembly 110, the foldable screen assembly 110 includes a first flat section 1104, a bending section 1108 and a second flat section 1106 connected in sequence, the first flat section 1104 and the second flat section 1106 can complete the folding action through the deformation of the bending section 1108; the second sealing member 130 avoids the side of the bending section 1108 away from the screen protective layer 111.

[0066] In this technical solution, in the first direction of the foldable screen assembly 110, the foldable screen assembly 110 includes a first flat section 1104, a bending section 1108, and a second flat section 1106 connected in sequence. The first flat section 1104 and the second flat section 1106 cannot deform and are two display areas that can be used individually or together. The bending section 1108, located between the first flat section 1104 and the second flat section 1106, can deform and can change the angle between the first flat section 1104 and the second flat section through a bending action, thus changing the folding angle of the foldable screen assembly 110.

[0067] Specifically, when the foldable screen assembly 110 is in the folded state, one of the first flat section 1104 and the second flat section 1106 displays content, while the other is off. Alternatively, the first flat section 1104 and the second flat section 1106 may display different content on their respective sides. When the foldable screen assembly 110 is in the unfolded state, the first flat section 1104, the bent section 1108, and the second flat section 1106 together form a complete large-size display area.

[0068] Based on this, the shape of the back of the bending segment 1108 changes accordingly during the dynamic bending process. By limiting the area of ​​the bending segment 1108 away from the screen protective layer 111 by the second sealing component 130, interference between the second sealing component 130 and the bending segment 1108 can be avoided, thereby ensuring the smoothness of the dynamic bending process of the folding screen assembly 110, and achieving the technical effect of improving the operability of the folding screen assembly 110 and optimizing the user operating experience.

[0069] Specifically, on the periphery of the bent section 1108, the periphery of the support plate 112 is flush with the periphery of the screen protective layer 111, or the periphery of the support plate 112 is recessed relative to the periphery of the screen protective layer 111, and the recessed dimension must be greater than or equal to 0.2mm.

[0070] like Figure 4 and Figure 5 As shown, in some embodiments, optionally, the second sealing member 130 includes: a first annular seal 132 disposed on the side of the first flat section 1104 away from the screen protective layer 111; and a second annular seal 134 disposed on the side of the second flat section 1106 away from the screen protective layer 111.

[0071] Figure 4 This is a schematic diagram of the structure of an electronic device 100 according to an embodiment of this application. Figure 4 The middle arrow c indicates the first direction of the foldable screen assembly 110. Figure 4 The middle circuit area 1109 is used to arrange the electrical control structure.

[0072] Figure 5 This is a schematic diagram of the structure of the first sealing component 120 and the second sealing component 130 according to embodiments of this application. Figure 5 The first annular seal 132 corresponds to the first flat section 1104 of the folding screen assembly 110, the second annular seal 134 corresponds to the second flat section 1106 of the folding screen assembly 110, and the first sealing component 120 corresponds to the bent section 1108 of the folding screen assembly 110. During the low-temperature injection process, the adhesive can flow in the area between the mold and the folding screen assembly 110 to facilitate overall injection.

[0073] The entire injection molding process involves one-time or multiple injection molding with multiple gates in a high-precision module. Multiple injection molding can ensure the accuracy and integrity of the filling.

[0074] In this technical solution, the second sealing component 130 includes a first annular seal 132 and a second annular seal 134. The first annular seal 132 is disposed on the side of the first flat area away from the screen protective layer 111, and the first annular seal 132 is conforming to the outer contour of the first flat area. By disposing of the first annular seal 132, a full-range sealing can be formed on the side of the first flat area away from the screen protective layer 111, thereby further reducing the possibility of sand and liquid contacting the internal layers of the foldable screen assembly 110, thus extending the service life of the foldable screen assembly 110 and improving the waterproof rating of the foldable screen assembly 110. The second annular seal 134 is disposed on the side of the second flat area away from the screen protective layer 111, and the second annular seal 134 is conforming to the outer contour of the second flat area. Its function is the same as that of the first annular seal 132, and will not be described in detail here.

[0075] like Figure 6 As shown, in some embodiments, the electronic device 100 may optionally include: a frame 140, the frame 140 including a frame 142 and a back panel 144, the folding screen assembly 110 being disposed inside the frame 142; a waterproof foam 150 being disposed on the back panel 144; and a second sealing member 130 being located between the folding screen assembly 110 and the waterproof foam 150.

[0076] Figure 6 This is a schematic diagram of the structure of an electronic device 100 according to an embodiment of this application.

[0077] In this technical solution, the electronic device 100 also includes a frame 140, and the foldable screen assembly 110 is disposed inside the frame 140.

[0078] Specifically, the frame 140 includes a frame 142 and a back panel 144. The frame 142 surrounds the folding screen assembly 110. A gap is left between the inner ring surface of the frame 142 and the folding screen assembly 110. A gap is also left between the inner surface of the frame 142 and the first sealing member 120 and the second sealing member 130 to allow for deformation allowance.

[0079] The back panel 144 is connected to the frame 140, and the back panel 144 is connected to the support plate 112 through a waterproof foam 150. The waterproof foam 150 can help the back panel 144 to position the folding screen assembly 110, and can also prevent liquid from entering the space below the back panel 144, thus preventing the electrical control structure below the back panel 144 from being damaged by contact with liquid, thereby improving the waterproof rating of the electronic device 100.

[0080] like Figure 6As shown, in some embodiments, optionally, the side of the screen protective layer 111 away from the first sealing member 120 is the front side of the folding screen assembly 110; the frame 142 avoids the front side of the folding screen assembly 110.

[0081] In this technical solution, the frame 142 avoids the space on the front side of the foldable screen assembly 110, that is, the frame 142 does not obstruct the foldable screen assembly 110.

[0082] Compared with related technologies, this application, by setting a first sealing component 120 that fully surrounds the foldable screen assembly 110 on all sides, and a second sealing component 130 that partially surrounds the foldable screen assembly 110 on one side away from the screen protective layer 111, enables the foldable screen assembly 110 to achieve a high level of dust and water resistance without the aid of decorative rings and pressure strips. This eliminates obstruction on the front of the foldable screen assembly 110, reduces the overall black border size, and improves the display performance of the electronic device 100. Furthermore, it saves on the cost of decorative rings and pressure strips, enhancing the market competitiveness of the electronic device 100. Additionally, it eliminates the need for adhesive application, simplifying the foldable screen module manufacturing process and reducing local costs.

[0083] Specifically, the electronic device 100 provided in this application has a waterproof rating of IP68.

[0084] Specifically, such as Figure 1 As shown, a first adhesive layer 114, a bent glass 115, and a second adhesive layer 116 are sequentially stacked between the screen protective layer 111 and the display layer 113. A support film 117 is also stacked between the display layer 113 and the support plate 112.

[0085] like Figure 2 As shown, a third adhesive layer 119 and a support foam 118 are stacked sequentially between the support plate 112 and the electrical connection section 1136.

[0086] The electronic device 100 can be a terminal or other devices besides a terminal. For example, the electronic device 100 can be a mobile phone, tablet computer, laptop computer, handheld computer, 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 personal computer (PC), television (TV), ATM, or self-service machine, etc. The embodiments of this application do not specifically limit it.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
