Description

Technical Field

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

[0002] With the rapid development of the electronics industry, electronic devices have gradually become indispensable products in people's daily lives. Electronic devices mainly consist of a casing and a display screen assembly, which enables functions such as screen display and program control.

[0003] In related technologies, decorative frames are typically included in electronic devices to connect the display assembly to the housing. The display assembly is mounted on the housing, and the decorative frame surrounds the display assembly, with one end connected to the housing and the other end pressing against the display assembly. This secures the display assembly to both sides via the housing and the decorative frame, preventing it from detaching. However, the decorative frame pressing against the display assembly creates a protrusion on one side of the screen, increasing the overall thickness of the electronic device. Furthermore, to prevent damage to the display assembly from the decorative frame pressing against it, foam is installed on the side of the decorative frame facing the display assembly, with gaps between the foam and the display assembly. Static electricity is unavoidable in daily life; when static electricity is generated, it can enter the electronic device through the gaps between the foam and the display assembly, potentially shocking the display assembly and affecting its display function. In the event of high voltage, static electricity can also enter the electronic device through the cavitation structure within the foam, affecting its display function.

[0004] Therefore, in related technologies, a decorative frame is also provided to fix the display component. However, the setting of the decorative frame will make the electronic device thicker, and the setting of the decorative frame and the display component will also provide a path for the transmission of static electricity. Static electricity can easily enter the inside of the electronic device and affect the display function of the display component. Summary of the Invention

[0005] This application provides an electronic device to address the problem in related technologies where the decorative frame makes the electronic device thicker and allows static electricity to easily enter the device, affecting the display function of the display assembly.

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

[0007] In a first aspect, embodiments of this application provide an electronic device, the electronic device including a display screen assembly and a housing, the display screen assembly including a protective layer and a display layer stacked together, the protective layer being connected to the display layer, the housing having a receiving cavity, the display layer being disposed in the receiving cavity and connected to the cavity wall of the receiving cavity, the protective layer being disposed at the cavity opening of the receiving cavity and connected to the housing, and in the direction from the protective layer to the display layer, the projection of the protective layer covering the projection of the display layer.

[0008] In this embodiment, the electronic device includes a display assembly and a housing. The display assembly includes a protective layer and a display layer stacked together, with the protective layer connected to the display layer. The housing has a receiving cavity, and the display layer is disposed within the receiving cavity and connected to the cavity wall. The protective layer is disposed at the cavity opening, allowing the display assembly to be installed within the housing. Since the protective layer is also connected to the housing, it can connect the display assembly to the housing, securing the display assembly and preventing it from detaching from the housing. In the direction from the protective layer to the display layer, the projection of the protective layer overlaps the projection of the display layer, resulting in a larger protective layer that extends beyond the edge of the display layer. This extended portion of the protective layer can extend outward at the cavity opening and connect to the housing; furthermore, the protective layer can completely cover the display layer, providing protection.

[0009] In other words, this application achieves the fixation of the display assembly through a protective layer, eliminating the need for a conventional decorative frame. On the one hand, since the decorative frame itself has thickness, the thickness of the electronic device proposed in this application will be reduced compared to electronic devices with decorative frames. On the other hand, the protective layer is directly connected to the housing and covers the display layer, avoiding the problem of gaps between the display layer assembly and the housing. This can prevent static electricity from entering the mounting cavity and striking the display assembly, thus preventing abnormal display function of the display assembly.

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of this application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0027] like Figures 3 to 13 As shown, the electronic device 100 includes a display screen assembly 10 and a housing 20. The display screen assembly 10 includes a protective layer 11 and a display layer 12 stacked together. The protective layer 11 is connected to the display layer 12. The housing 20 has a receiving cavity 21. The display layer 12 is disposed in the receiving cavity 21 and is connected to the cavity wall of the receiving cavity 21. The protective layer 11 is disposed at the cavity opening of the receiving cavity 21 and is connected to the housing 20. In the direction from the protective layer 11 to the display layer 12, the projection of the protective layer 11 covers the projection of the display layer 12.

[0028] In this embodiment, the electronic device 100 includes a display screen assembly 10 and a housing 20. The display screen assembly 10 includes a protective layer 11 and a display layer 12 stacked together, with the protective layer 11 connected to the display layer 12. The housing 20 has a receiving cavity 21, with the display layer 12 disposed in the receiving cavity 21 and connected to the cavity wall. The protective layer 11 is disposed at the opening of the receiving cavity 21, thereby allowing the display screen assembly 10 to be installed in the housing 20. Since the protective layer 11 is also connected to the housing 20, the display screen assembly 10 can be connected to the housing 20 through the protective layer 11, thus fixing the display screen assembly 10 and preventing the display screen assembly 10 from detaching from the housing 20. In the direction from the protective layer 11 to the display layer 12, the projection of the protective layer 11 covers the projection of the display layer 12, so the size of the protective layer 11 is large, allowing the protective layer 11 to extend beyond the edge of the display layer 12. Thus, the extended part of the protective layer 11 can extend outward at the cavity opening of the receiving cavity 21 and connect with the housing 20; and the protective layer 11 can also completely cover the display layer 12 to protect it.

[0029] That is, this application fixes the display assembly 10 by means of the protective layer 11 of the display assembly 10, eliminating the conventional decorative frame 200. On the one hand, since the decorative frame 200 itself has thickness, the thickness of the electronic device 100 proposed in this application will be reduced compared to the electronic device 100 with the decorative frame 200. On the other hand, the protective layer 11 is directly connected to the housing 20 and covers the display layer 12, avoiding the problem of gaps between the display layer assembly 10 and the housing 20. This can prevent static electricity from entering the mounting cavity 21 and hitting the display assembly 10, which could cause abnormal display function of the display assembly 10.

[0030] In addition, in related technologies, the decorative frame protrudes from the display assembly, which causes a protruding part on one side of the screen of the electronic device, resulting in a problem of scratching the hand. However, this application eliminates the decorative frame, which also makes the side of the electronic device 100 where the display assembly 10 is located smoother, avoiding the protruding part on the electronic device 100 caused by the decorative frame 200, and preventing the problem of scratching the hand.

[0031] It should be noted that the electronic device 100 in this application can be a variety of devices with a display screen assembly 10, including but not limited to mobile phones, tablets, laptops, PDAs, and other terminals. Especially for devices such as foldable screen phones, the display screen assembly 10 is a foldable screen, which will be used in daily use by unfolding and folding. During the unfolding and folding process, there will be misalignment of the layers in the foldable screen and movement relative to the shell 20, which poses a significant risk of the foldable screen falling off. This application can better fix and protect the foldable screen, reducing the thickness of the foldable screen phone. In the embodiments of this application, no specific limitation is made in this regard.

[0032] In addition, such as Figure 1 As shown, Figure 1 The diagram illustrates the connection between the display assembly 10 and the housing 20 in an electronic device 100 in the related art. A decorative frame 200 presses against the display assembly 10. Due to limitations in the thickness of the material and assembly tolerances of the decorative frame 200, it is generally about 0.4 mm higher than the display assembly 10. Figure 1As shown in Figure H, eliminating the decorative frame 200 in this application reduces the thickness of the electronic device 100 by approximately 0.4 mm. Furthermore, to ensure the display assembly 10 can function properly, the display layer 12 contains numerous micron-level control circuits and light-emitting materials. To protect these control circuits and light-emitting materials, a protective layer 11 is provided on top of the display layer 12. In this application, when connecting the display assembly 10 to the housing 20, the outermost protective layer 11 of the original display assembly 10 can be enlarged, directly connecting the protective layer 11 to the housing 20. This avoids introducing an additional protective layer 11 component, resulting in a better thickness reduction effect for the electronic device 100.

[0033] Continue to refer to Figure 1 When the electronic device 100 is displaying normally, a black border may appear, such as... Figure 1 As mentioned in section L, the black border cannot be displayed, and a wide black border reduces the user experience. The width L of the black border is mainly limited by a, b, c, and d, such as... Figure 2 As shown. Where a is the distance between the edge of the display area of ​​the display assembly 10 and its outer edge, which is related to the size and manufacturing of the display layer 12; b is the distance between the outer edge of the display assembly 10 and the cavity wall of the receiving cavity 21, which is related to the manufacturing of the housing 20, the fit tolerance between the housing 20 and the display assembly 10, and, when the display assembly 10 is a foldable screen, this dimension is also related to the misalignment during folding and the relative movement of the foldable screen to the housing 20; c is the overlap width between the decorative frame 200 and the housing 20, to support the decorative frame 200 and prevent it from sagging or even damaging the display assembly 10; d is the distance between the outer side of the decorative frame 200 and the outer side of the housing 20. Currently, the industry standard for overall black border width is above 4mm.

[0034] In this application, such as Figure 4 As shown, after removing the decorative frame 200, the width of the black border is defined by a, b, and e. a and b can be referred to the above explanation, and e is the distance between the edge of the housing 20 and the cavity wall of the receiving cavity 21. In the prior art, the distance between the edge of the housing 20 and the cavity wall of the receiving cavity 21 is c+d. Since the decorative frame 200 is removed, there is no need to set the overlap width c between the decorative frame 200 and the housing 20, making e < c+d. This reduces the width of the black border of the electronic device 100, improving the user experience. In the prior art, to achieve a better overlap effect of the decorative frame 200, the overlap between the decorative frame 200 and the housing 20 is usually set to exceed 1mm. Therefore, the width of the black border of the electronic device 100 proposed in this application can be reduced by about 1mm, making the black border width less than 3mm.

[0035] It should also be noted that the electronic device typically includes a back cover, a display assembly 10, and a mid-frame. The back cover and the display assembly 10 are positioned opposite each other and are located on both sides of the mid-frame. In this application, the housing 20 can be the mid-frame. Of course, with the continuous development of technology, the back cover and the mid-frame in the electronic device 100 can also be manufactured as a whole. In this case, the housing 20 is the whole of the mid-frame and the back cover. The specific form of the housing 20 is not specifically limited in this embodiment.

[0036] Additionally, in some embodiments, such as Figure 3 , Figure 6 , Figure 8 As shown, a carrier 22 can be connected to the cavity wall of the receiving cavity 21. The carrier 22 carries the display layer 12. At the cavity opening of the receiving cavity 21, an installation groove 23 is provided on the outer wall of the housing 20. Part of the protective layer 11 is connected to the bottom of the installation groove 23.

[0037] A support member 22 is connected to the cavity wall of the receiving cavity 21. The support member 22 can support the display layer 12, thereby placing the display assembly 10 of the housing 20 in the housing 20 and preventing the display from sagging. At the cavity opening of the receiving cavity 21, a mounting groove 23 is provided on the outer wall of the housing 20, so that the part of the protective layer 11 extending from the cavity opening can be located in the mounting groove 23 and connected to the bottom of the mounting groove 23, so as to realize the connection between the protective layer 11 and the housing 20.

[0038] The housing 20 has a cavity 21 inside, so that the housing 20 has an inner wall inside the cavity 21 and an outer wall outside the cavity 21. In the electronic device 100, the outer wall of the housing 20 can form the outer surface of the electronic device 100, constituting the appearance of the electronic device 100, which can be touched by the user. The mounting groove 23 can provide mounting space for the protective layer 11, which can avoid the problem of the protective layer 11 protruding from the housing 20 when it is directly connected to the outer wall of the housing 20 without the mounting groove 23. This can make the appearance of the electronic device 100 smoother and prevent the protective layer 11 from scratching the hand.

[0039] In order for the electronic device to function properly and for the display assembly 10 to display correctly, a cut-out area is typically provided in the middle of the support member 22. Other components, such as batteries, are usually placed on the side of the support member 22 away from the display assembly 10 or at the cut-out area. The display assembly 10 is electrically connected to these components via the cut-out area. Therefore, in this application, the support member 22 specifically supports the edge of the display 12 and is connected to the edge of the display layer 12.

[0040] It should be noted that double-sided adhesive, waterproof adhesive, or other adhesives can be applied to the portion where the protective layer 11 connects to the bottom of the mounting groove 23, and between the bottom of the mounting groove 23 and the protective layer 11, to bond them together. The protective layer 11 can be bonded using an adhesive dispensing process. (See also...) Figure 1 In related technologies, the protective layer 11 and the pressure-sensitive adhesive 17 are stacked to connect with other parts of the display assembly 10. In this application, when the adhesive is provided between the protective layer 11 and the bottom of the mounting groove 23, the adhesive can be the pressure-sensitive adhesive 17.

[0041] It should also be noted that, in order to make the surface of the electronic device 100 smoother, the depth of the mounting groove 23 can be set according to the thickness of the protective layer 11 and the thickness of the colloid, so that after the protective layer 11 is connected to the bottom of the mounting groove 23, the protective layer 11 can be flush with the outer wall of the housing 20.

[0042] Additionally, in some embodiments, such as Figure 3 , Figure 6 , Figure 8 The surface of the bottom of the mounting groove 23 shown can be an arc surface or a plane, and the protective layer 11 located in the mounting groove 23 covers the bottom of the mounting groove 23.

[0043] The bottom of the mounting groove 23 can have either a curved surface or a flat surface. Therefore, when setting the connecting protective layer 11, the protective layer 11 can also have either a curved surface or a flat surface. The following describes the two forms in detail:

[0044] The surface of the bottom of the mounting groove 23 is curved. Since the protective layer 11 located in the mounting groove 23 covers the bottom of the mounting groove 23, the part of the protective layer 11 connected to the mounting groove 23 has the same shape as the bottom of the mounting groove 23, which is also curved. Thus, the part of the protective layer 11 extending out of the cavity and the bottom of the mounting groove 23 are both curved, and they are compatible with each other. The curvature of the protective layer 11 and the bottom of the mounting groove 23 are consistent, which facilitates the connection between the two. That is, in this embodiment, after the shape of the protective layer 11 is enlarged, the protective layer 11 can be curved along the mounting groove 23 and connect with the curved bottom of the mounting groove 23. Thus, the extended part of the protective layer 11 can be curved. Since the edge of the housing 20 is the area where the user holds and touches it, it is generally also curved. This makes it easier to set the mounting groove 23 on the housing 20. The protective layer 11 also bends with the curved surface of the housing 20, which makes the grip and touch feel of the electronic device 100 smoother.

[0045] When the surface where the bottom of the mounting groove 23 is located is curved, the protective layer 11 can take different forms, such as... Figure 3As shown, the protective layer 11 can also be a waterfall-style protective layer 11. In this configuration, the mounting groove 23 is longer, and the extension of the protective layer 11 is also longer. In the stacking direction of the protective layer 11 and the display layer 12, the distance between the edge of the flat portion in the middle of the protective layer 11 and the edge of the extended curved portion can be greater than 2mm, for example, it can be 3mm, 2.9mm, 2.8mm, etc. Figure 6 As shown, the protective layer 11 can also be a slightly curved protective layer 11. In this configuration, the length of the mounting groove 23 is shorter, and the extension of the protective layer 11 is also shorter. In the stacking direction of the protective layer 11 and the display layer 12, the distance between the edge of the planar portion in the middle of the protective layer 11 and the edge of the extended curved portion can be less than or equal to 2 mm, for example, it can be 1.5 mm, 1 mm, 1.7 mm, etc. The length of the mounting groove 23 and the extension length of the protective layer 11 are not specifically limited in this embodiment.

[0046] The surface where the bottom of the mounting slot 23 is located is a plane, such as... Figure 8 As shown, since a portion of the protective layer 11 located in the mounting groove 23 covers the bottom of the groove 23, the portion of the protective layer 11 connected to the mounting groove 23 has the same shape as the bottom of the groove 23, which is also planar. This allows the bottom of the mounting groove 23 and the protective layer 11 to fit together, facilitating their connection. In this configuration, the protective layer 11 is planar; by simply enlarging its shape, the original shape of the protective layer 11 can be maintained, avoiding bending operations and simplifying the manufacturing process.

[0047] Additionally, when the surface where the bottom of the mounting groove 23 is located is flat, the protective layer 11 of the housing 20 can also be made to be at the same height, such as... Figure 8 As shown, the mounting groove 23 can be set on the flat portion of the housing 20. After the protective layer 11 is connected, the flat portion of the housing 20 is at the same height as the protective layer 11, so the housing 20 can also protect the protective layer 11. For example, if the electronic device 100 is dropped from a height, in addition to the protective layer 11 outside the display assembly 10, the housing 20 can also bear part of the force, distributing the force acting on the display assembly 10, which can prevent the force from acting directly on the protective layer 11 and easily damaging it. Furthermore, if the electronic device 100 is bumped or hits an edge, the edge of the housing 20 will also bear the force first, which can prevent the force from acting directly on the protective layer 11.

[0048] Additionally, in some embodiments, such as Figure 4 , Figure 6 , Figure 8As shown, the display assembly 10 may further include a support layer 13, which is disposed on the side of the display layer 12 away from the protective layer 11. The support layer 13 has a connecting portion 131 and a protective portion 132. The protective portion 132 extends along the circumferential direction of the connecting portion 131 and is connected to the periphery of the connecting portion 131. The connecting portion 131 is connected to the display layer 12, and the protective portion 132 extends out of the display layer 12. Both the connecting portion 131 and the protective portion 132 are connected to the cavity wall of the receiving cavity 21. The protective portion 132 is used to protect the display layer 12.

[0049] The display assembly 10 also includes a support layer 13, which is disposed on the side of the display layer 12 away from the protective layer 11, so that the protective layer 11, the display layer 12, and the support layer 13 are stacked in sequence. The connecting part 131 and the protective part 132 can both be connected to the cavity wall of the receiving cavity 21, so that the connection between the display assembly 10 and the housing 20 is relatively stable.

[0050] The support layer 13 has a connecting portion 131 and a protective portion 132. The protective portion 132 extends along the circumferential direction of the connecting portion 131 and is connected to the periphery of the connecting portion 131. That is, the protective portion 132 is connected around the circumference of the connecting portion 131. The connecting portion 131 is located in the middle of the support layer 13. The connecting portion 131 can be connected to the display layer 12 to realize the stacked connection of the display layer 12 and the support layer 13. The protective portion 132 can extend beyond the display layer 12, thereby protecting the protective layer 11 and the display layer 12 in the stacking direction. The projection of the protective part 132 is located outside the projection of the display layer 12. That is, the size of the support layer 13 is larger than that of the display layer 12, so a portion of the support layer 13 (the protective part 132) can extend from the edge of the display layer 12. Therefore, the protective part 132 is located outside the display assembly 10. When the display assembly 10 collides with other external components, the protective part 132 can first abut against the other external components, preventing them from directly impacting the display layer 12 and thus protecting it. Especially during the manufacturing process of the display assembly 10, clamps, tweezers, and other devices are required. The protective part 132 provides a working position for the clamps and tweezers and prevents them from touching the display layer 12 and causing damage.

[0051] Additionally, in some embodiments, such as Figure 6 As shown, the protective part 132 may include a first folded edge 1321, which is connected to the connecting part 131. The first folded edge 1321 and the connecting part 131 have a first angle. The first folded edge 1321 is located between the cavity wall of the receiving cavity 21 and the display layer 12. The first folded edge 1321 is connected to the cavity wall of the receiving cavity 21.

[0052] The protective portion 132 includes a first folded edge 1321, which is connected to both the connecting portion 131 and the cavity wall of the receiving cavity 21. Since there is a first angle between the first folded edge 1321 and the connecting portion 131, they are located on different planes. Therefore, the protective portion 132 and the connecting portion 131 can form an L-shaped structure. Because the first folded edge 1321 is located between the cavity wall of the receiving cavity 21 and the display layer 12, it can wrap around the edge of the display layer 12, thereby protecting the display layer 12.

[0053] It should be noted that, as Figure 6 , Figure 3 As shown in the figure, α is the first angle. The first angle can determine the degree of inclination of the first folded edge 1321. In order to avoid the first folded edge 1321 tilting towards the display layer 12 and to prevent the first folded edge 1321 from colliding with the display layer 12 and damaging the display layer 12, the first angle can satisfy: 90°≤α<180°. Specifically, the first angle can be 90°, 135°, 140°, 150°, 120°, 144°, etc. The specific value of the first angle is not specifically limited in this embodiment of the application.

[0054] Additionally, in some embodiments, such as Figure 3 As shown, the protective part 132 may also include a second folded edge 1322, which is connected to the first folded edge 1321. The second folded edge 1322 and the first folded edge 1321 have a second angle. The second folded edge 1322 is located between the cavity wall of the receiving cavity 21 and the display layer 12, and is connected to both the cavity wall of the receiving cavity 21 and the protective layer 11.

[0055] The protective portion 132 may further include a second folded edge 1322, which is connected to the first folded edge 1321. The second folded edge 1322 and the first folded edge 1321 have a second angle, thus the second folded edge 1322 can be located on different planes from the first folded edge 1321. In this case, the protective portion 132 and the connecting portion 131 can form a shape similar to a "Z". Since the second folded edge 1322 is also located between the cavity wall of the receiving cavity 21 and the display layer 12, the first folded edge 1321 wraps around the edge of the display layer 12, and the second folded edge 1322 allows the protective portion 132 to extend further outward, resulting in a longer extended portion and better protection for the display layer 12.

[0056] The second folded edge 1322 is connected to the cavity wall of the receiving cavity 21 and the protective layer 11, so that the protective layer 11 and the protective part 132 can form a sealed space, which can seal the display layer 12 and also play a role in preventing water vapor and dust.

[0057] It should be noted that, as Figure 3 As shown in the figure, β is the second angle, which determines the inclination of the second fold 1322. To avoid interference between the inclination of the second fold 1322 and the protective layer 11, the second angle can satisfy: 0 < β ≤ 90°. Specifically, the first angle can be 90°, 70°, 80°, 86°, 65°, etc. The specific value of the second angle is not specifically limited in this embodiment. In order to simplify the manufacturing of the support layer 13, when the protective part 132 includes the first fold 1321 and the second fold 1322, both the first angle and the second angle can be 90°.

[0058] It should also be noted that, in the two cases where the protective part 132 includes the first folded edge 1321 and the protective part 132 includes both the first folded edge 1321 and the second folded edge 1322, in order to make the protective part 132 provide better protection for the display layer 12, the distance between the projection of the edge of the protective part 132 and the projection of the edge of the connecting part 131 on the plane where the display layer 12 is located should be greater than 0.2mm.

[0059] Additionally, in some embodiments, such as Figure 8 As shown, the protective part 132 and the connecting part 131 can be located on the same plane.

[0060] The protective part 132 and the connecting part 131 are located on the same plane, so the support layer 13 is a planar structure, and the part of the support layer 13 that extends out of the display layer 12 is coplanar with the connecting part 131. The protective part 132 and the connecting part 131 can form a "I" shaped structure, which facilitates the production of the support layer 13.

[0061] It should be noted that, in order to ensure that the protective part 132 provides better protection for the display layer 12, the distance between the edge of the protective part 132 and the edge of the connecting part 131 should be greater than 0.2 mm.

[0062] Additionally, in some embodiments, such as Figure 8 As shown, the display layer 12 may have a first surface 121, a second surface 122 and a side surface 123. The first surface 121 and the second surface 122 are opposite to each other. The first surface 121 is connected to the protective layer 11. The second surface 122 is connected to the cavity wall of the receiving cavity 21. The side surface 123 is located between the first surface 121 and the second surface 122. At least one of the second surface 122 and the side surface 123 is provided with a coating 18.

[0063] The display layer 12 has a first surface 121, a second surface 122, and a side surface 123. The first surface 121 and the second surface 122 are opposite to each other, and the side surface 123 is located between the first surface 121 and the second surface 122. The first surface 121 can be connected to the protective layer 11, and the second surface 122 can be connected to the cavity wall of the receiving cavity 21. That is, the stacking direction of the protective layer 11 and the display layer 12 is from the first surface 121 to the second surface 122. At least one of the second surface 122 and the side surface 123 is provided with a coating 18. The coating 18 can enable the display assembly 10 to have other properties to meet the usage requirements.

[0064] Additionally, in some embodiments, such as Figure 5 , Figure 7 , Figure 9 As shown, the coating 18 can be at least one of waterproof coating 181, conductive coating 182, heat dissipation coating 183, and microwave absorbing coating 184.

[0065] The coating 18 can be of various types, and each coating 18 can have specific properties to enable the display assembly 10 to also have other functions. For example, the coating 18 can include a waterproof coating 181, a conductive coating 182, a heat dissipation coating 183, and a microwave absorbing coating 184. The coating 18 can be at least one of the following: a waterproof coating 181, a conductive coating 182, a heat dissipation coating 183, and a microwave absorbing coating 184.

[0066] The second surface 122 of the display layer 12 is the location where the display assembly 10 is made conductive. At the location on the second surface 122 where conductivity is required, only a conductive coating 182 may be provided. Other locations on the second surface 122 may be provided with at least one of the following: a waterproof coating 181, a conductive coating 182, a heat dissipation coating 183, and a microwave absorbing coating 184. Figure 13 As shown in the figure, the area indicated by point E may not have conductive properties and is an area where one or more of the following are applied: waterproof coating 181, conductive coating 182, heat dissipation coating 183, and wave-absorbing coating 184.

[0067] A waterproof coating 181 is formed by depositing a hydrophobic material on the second surface 122 and / or the side surface 123, thereby giving the display assembly 10 waterproof properties.

[0068] The heat dissipation coating 183 is a material with heat dissipation properties deposited on the second surface 122 and / or side surface 123. For example, graphene can be sprayed onto the second surface 122 and / or side surface 123. Since graphene has good thermal conductivity, this coating can enable the display module to have good heat dissipation performance.

[0069] Wave-absorbing coating 184: This involves depositing wave-absorbing material onto the second surface 122 and / or side surface 123. The wave-absorbing material refers to a functional material that can absorb and attenuate the energy of incident electromagnetic waves and reduce or eliminate reflected electromagnetic waves. Examples include ferrite wave-absorbing materials, metal micropowder wave-absorbing materials, polycrystalline iron fiber wave-absorbing materials, nano-wave-absorbing materials, and plasma wave-absorbing materials. One or more layers of wave-absorbing material can be sprayed onto the second surface 122 and / or side surface 123 to give the display assembly 10 the function of absorbing and attenuating electromagnetic waves.

[0070] Conductive coating 182: Conductive spheres 1821 are added to the coating material, and the coating material and conductive spheres 1821 are deposited on the second surface 122 and / or side surface 123 by physical vapor deposition or chemical vapor deposition. For example... Figure 10 As shown, the conductive sphere 1821 includes a gold or copper sphere core 1822, and the outer surface of the sphere core 1822 has an insulating resin coating layer 1823. After depositing the conductive film 182, pressure can be applied to the area on the second surface 122 that needs to be conductive, causing the insulating resin coating layer 1823 to rupture, such as... Figure 11 As shown, the exposed spherical core 1822 allows the inner shell of the spherical core to achieve conductivity between the second surface 122 and other components. For areas on the second surface 122 and side surfaces 123 where conductivity is not required, no pressure is applied; the insulating resin coating layer 1823 maintains its enclosure of the spherical core 1822, keeping it insulated. The direction of applied pressure can be aligned with the stacking direction of the protective layer 11 and the display layer 12. In this case, the top and bottom of the spherical core 1822 are exposed, and the top and bottom of the conductive coating 182 are conductive, enabling conductivity between the display layer 12 components. In areas where no pressure is applied, insulation is maintained to improve the anti-static performance of the electronic device 100. A nickel-plated layer or a gold-plated layer can also be provided around the periphery of the spherical core 1822.

[0071] It should be noted that the coating is at least one of a waterproof coating 181, a conductive coating 182, a heat dissipation coating 183, and a microwave absorbing coating 184. When the coating is of one type, it can be directly deposited on the second surface 122 and / or the side surface 123. When there are multiple coatings, they can be deposited sequentially to form a multilayer coating. For example, when the coating includes a waterproof coating 181, a conductive coating 182, a heat dissipation coating 183, and a microwave absorbing coating 184, the waterproof coating 181 can be deposited first, then the microwave absorbing coating 184 can be deposited on the waterproof coating 181, then the heat dissipation coating 183 can be deposited on the microwave absorbing coating 184, and then the conductive coating 182 can be deposited on the heat dissipation coating 183. The specific type and quantity of the coating can be set according to actual needs. When there are multiple coatings, the deposition order of the multiple coatings can also be set according to actual needs. This application embodiment does not make specific limitations here.

[0072] It should also be noted that the display assembly 10 includes other layers, such as Figure 3 As shown, for example, the components include ultra-thin glass 16, optical adhesive 15, foam tape 14, driver integrated circuit chip (D-IC), and rigid flexible printed circuit board 19 (RFPC). The D-IC is disposed on the RFPC, and the foam tape 14 is disposed on the side of the support layer 13 away from the display layer 12. The foam tape 14 has a cutout area, and the RFPC is disposed on the cutout area. The ultra-thin glass 16 and optical adhesive 15 are disposed between the protective layer 11 and the display layer 12, and are stacked. Coatings can be provided on the sides 123 of the ultra-thin glass 16, optical adhesive 15, foam tape 14, and display layer 12. If a conductive coating 182 is also provided on the side 123, the conductive coating 182 does not require conductivity and no pressure needs to be applied to it.

[0073] At this time, the surfaces of the foam tape 14 and the RFPC facing away from the display layer 12 constitute the back of the display assembly 10. To ensure the normal functioning of the display assembly 10, the back of the RFPC has exposed copper contact areas. These exposed copper contact areas need to achieve vertical conductivity. The coating on the exposed copper contact areas is a conductive coating 182. After applying the conductive coating 182, pressure needs to be applied to expose the crystal core 1822 and achieve conductivity. Other areas on the back of the display assembly 10 do not require conductivity. At least one of the following can be applied: a waterproof coating 181, a conductive coating 182, a heat dissipation coating 183, and a wave-absorbing coating 184. If a conductive coating 182 is applied to the back of the display assembly 10, pressure need not be applied. Since the protective portion 132 of the support layer 13 needs to connect to the cavity wall of the receiving cavity 21, the support layer 13 is relatively long and extends beyond the foam tape 14. A conductive coating 182 can also be applied to the edge area of ​​the back of the support layer 13, and pressure need not be applied. Figure 12 As shown in the figure, the area indicated by point D is the area where the conductive coating 182 is applied. The area indicated by D includes the edge area of ​​the back side of the support layer 13 and the exposed copper contact area on the back side of the RFPC.

[0074] Additionally, in some embodiments, such as Figure 3 , Figure 6 , Figure 8 As shown, an adhesive 30 may be connected between the protective part 132 and the cavity wall of the receiving cavity 21; the adhesive 30 has at least one of the following properties: waterproof, wave-absorbing, heat dissipation, and thermal conductivity.

[0075] An adhesive 30 is used to connect the protective part 132 and the cavity wall of the receiving cavity 21, so that the protective part 132 and the cavity wall of the receiving cavity 21 can be connected by the adhesive 30. The adhesive 30 has at least one of the following properties: waterproof, wave-absorbing, heat dissipation, and thermal conductivity, and can be configured according to the needs of different electronic devices 100.

[0076] The performance of the adhesive 30 can be configured by changing its components. For example, the adhesive 30 may include hydrophobic materials, ferrite, graphene, and conductive spheres 1821. The hydrophobic material enables the adhesive 30 to have waterproof properties, the ferrite enables it to have wave-absorbing properties, the graphene enables it to have heat dissipation properties, and the conductive spheres 1821 enable it to have conductive properties. The conductive spheres 1821 can be referenced in the above description of conductive spheres 1821 in point-to-point coating. When the adhesive 30 needs to have conductive properties, the adhesive 30 can be filled between the protective part 132 and the housing 20. Before the adhesive cures, pressure is applied to the adhesive to cause the insulating resin coating layer 1823 to rupture, exposing the internal sphere core 1822. The sphere core 1822 connects the folding screen module and the grounding area of ​​the housing 20. In different electronic devices 100, the adhesive 30 may need to have different properties, and the composition of the adhesive 30 can be adjusted to obtain adhesive 30 with different properties.

[0077] In addition, when the adhesive 30 has conductive properties, the crystal core 1822 can conduct electricity between the display assembly 10 (support layer 13) and the housing 20 (around the cavity 21), forming an electrostatic shielding cavity, which further improves the anti-static capability of the electronic device 100 and prevents electrostatic discharge from hitting the inside of the display assembly 10, thus avoiding abnormal display function of the display assembly 10.

[0078] In addition, in this embodiment, the protective layer 11 has three forms: waterfall-type protective layer 11, micro-curved surface protective layer 11, and planar protective layer 11. The mounting groove 23 of the waterfall-type protective layer 11 is relatively long, and the connection part 131 between the protective layer 11 and the shell 20 is relatively long, which can make the connection between the protective layer 11 and the shell 20 more stable. The mounting groove 23 of the micro-curved surface protective layer 11 is relatively short, and there is less bending of the protective layer 11, which is convenient for manufacturing. The planar protective layer 11 can avoid bending the protective layer 11, reduce the complexity of the process, improve the production yield and efficiency, and has a cost advantage. The protective layer formed by the protective part 132 and the connecting part 131 also has three forms: a "Z"-shaped support layer 13, an "L"-shaped support layer 13, and an "I"-shaped support layer 13. The "Z"-shaped support layer 13 can be connected to the protective layer 11 and can play a sealing role. The "L"-shaped support layer 13 has the same wrapping effect as the "Z"-shaped support layer 13 on the display layer 12 and can also reduce the complexity of the process. The "I"-shaped support layer 13 can greatly simplify the processing process while protecting the display layer 12. The three forms of the protective layer 11 and the three forms of the protective layer can be combined arbitrarily. For example, the waterfall-style protective layer 11 can be combined with the "Z"-shaped support layer 13, such as... Figure 3 As shown, the micro-curved protective layer 11 can be combined with the "L"-shaped support layer 13, such as... Figure 6 As shown, the planar protective layer 11 can be combined with the "I"-shaped support layer 13, such as... Figure 8 As shown, the waterfall-style protective layer 11 can also be combined with the "I"-shaped support layer 13, the planar protective layer 11 can be combined with the "Z"-shaped support layer 13, and so on. This application does not make specific limitations on this aspect.

[0079] Furthermore, as described above, the coating and adhesive 30 can also have various forms. One or more layers of coating can be set as needed, or the composition of adhesive 30 can be different as needed. The coating and adhesive 30 can also be arbitrarily combined with the three forms of the protective layer 11 and the three forms of the protective layer mentioned above.

[0080] In this embodiment, the electronic device 100 includes a display screen assembly 10 and a housing 20. The display screen assembly 10 includes a protective layer 11 and a display layer 12 stacked together, with the protective layer 11 connected to the display layer 12. The housing 20 has a receiving cavity 21, in which the display screen assembly 10 is disposed and connected to the cavity wall. The protective layer 11 is disposed at the opening of the receiving cavity 21, thereby allowing the display screen assembly 10 to be installed in the housing 20. Since the protective layer 11 is also connected to the housing 20, the display screen assembly 10 can be connected to the housing 20 through the protective layer 11, thus fixing the display screen assembly 10 and preventing it from detaching from the housing 20. In the direction from the protective layer 11 to the display layer 12, the projection of the protective layer 11 covers the projection of the display layer 12, so the size of the protective layer 11 is large, allowing the protective layer 11 to extend beyond the edge of the display layer 12. Thus, the extended part of the protective layer 11 can extend outward at the cavity opening of the receiving cavity 21 and connect with the housing 20; and the protective layer 11 can also completely cover the display layer 12 to protect it.

[0081] That is, this application fixes the display assembly 10 by means of the protective layer 11 of the display assembly 10, eliminating the conventional decorative frame 200. On the one hand, since the decorative frame 200 itself has thickness, the thickness of the electronic device 100 proposed in this application will be reduced compared to the electronic device 100 with the decorative frame 200. On the other hand, the protective layer 11 is directly connected to the housing 20 and covers the display layer 12, avoiding the problem of gaps between the display layer assembly 10 and the housing 20. This can prevent static electricity from entering the mounting cavity 21 and hitting the display assembly 10, which could cause abnormal display function of the display assembly 10.

[0082] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
