Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to a housing assembly, a support assembly, a flexible display screen, and an electronic device. Background Technology

[0002] People generate static electricity during activities, which is then transferred to electronic devices when using them. Because electronic devices often contain carbon fiber composite panels, and the carbon fibers in these panels continuously accumulate charge, and because the carbon fiber filaments are sealed with insulating adhesive, the static charge concentrated in the composite panel cannot dissipate. When the charge accumulates to a certain threshold, it is directly released to the nearest electronic device, causing it to burn out.

[0003] Therefore, how to solve the above problems has become an urgent issue to be addressed. Utility Model Content

[0004] This application provides a housing assembly, a support assembly, a flexible display screen, and an electronic device. The housing assembly has a conductive part that is electrically connected to carbon fiber filaments to release the charge generated by the carbon fiber filaments to the outside.

[0005] In a first aspect, this application provides a housing assembly. The housing assembly includes a housing body, a conductive portion, and a shielding portion. The housing body includes a light-transmitting area and carbon fiber filaments. The housing body has a first surface and a second surface disposed opposite to each other. A portion of the carbon fiber filaments is exposed on the first surface of the housing. The conductive portion and the shielding portion are both disposed on the first surface of the housing body. Specifically, the projection of the shielding portion onto the first surface at least partially covers the projection of the light-transmitting area onto the first surface; at least a portion of the conductive portion contacts and is electrically connected to the exposed carbon fiber filaments; and the end of the conductive portion away from the first surface is used for electrical connection with a conductive element.

[0006] In this embodiment, the conductive part of the housing assembly can be connected to the carbon fiber filaments exposed on the first surface of the housing body. Static charge in the housing body can be discharged through the conductive part and then released to other grounded components through a conductive element connected to the conductive part. This prevents charge from being directly released to the nearest electronic device, thus improving the lifespan of the electronic device. Furthermore, the projection of the blocking part on the first surface at least partially covers the projection of the light-transmitting area on the first surface, reducing the light transmittance of the light-transmitting area and thereby reducing the light transmission of the housing assembly.

[0007] In one embodiment, the shell body may include an insulating layer and carbon sheets, the carbon sheets comprising carbon fiber filaments. The carbon sheets are embedded in the insulating layer, with gaps existing between at least partially adjacent carbon sheets, and multiple gaps at least partially overlapping along the thickness direction of the insulating layer, forming a light-transmitting area. The insulating layer may be resin, which is transparent; therefore, the carbon sheets disposed within the resin (insulating layer) can be observed. When gaps exist between adjacent carbon sheets, and these gaps are interconnected along the thickness direction of the resin, a transparent area is formed on the resin, i.e., a light-transmitting area is formed on the insulating layer.

[0008] In one embodiment, the shielding portion includes a paint layer, a portion of the first surface is coated with the paint layer, and the projection of the paint layer on the first surface at least partially covers the projection of the light-transmitting area on the first surface. The conductive portion is disposed on the portion of the first surface not covered by the paint layer and contacts and is electrically connected to the carbon fiber filaments exposed in that portion. In this embodiment, the shielding portion and the conductive portion can be disposed in the same layer, and the conductive portion can completely cover the portion not covered by the paint layer.

[0009] In one embodiment, the shielding portion includes a paint layer, with a portion of the first surface coated with the paint layer. The projection of the paint layer onto the first surface at least partially covers the projection of the light-transmitting area onto the first surface. The conductive portion is disposed on the side of the paint layer facing away from the shell body, and a portion of the exposed carbon fiber filaments of the conductive portion contacts and is electrically connected to it. In this embodiment, the shielding portion can be understood as being embedded between the conductive portion and the first surface of the shell body, with a portion of the conductive portion able to contact the first surface of the shell body to ensure that electrostatic charges in the shell body can be discharged.

[0010] In one embodiment, the conductive portion includes a silver paste layer, at least a portion of which is applied to the first surface of the shell body via a printing process, contacting and electrically connecting with the exposed carbon fiber filaments. The conductive portion also includes a metal layer, at least a portion of which is applied to the first surface of the shell body via a physical vapor deposition process, contacting and electrically connecting with the exposed carbon fiber filaments. The conductive portion can also be of other forms, as long as it can contact and electrically connect with the exposed carbon fiber filaments to discharge electrostatic charges within the shell body. The material of the conductive portion can be one or a mixture of nickel, chromium, silver, or copper.

[0011] In one embodiment, the housing assembly further includes a conductive element electrically connected to the end of the conductive portion away from the housing body. The conductive element is capable of dissipating electrostatic charge flowing to the conductive portion to prevent the accumulation of electrostatic charge within the housing body.

[0012] Secondly, this application also provides an electronic device comprising: a first middle frame, a conductive element, a first adhesive element, and a housing assembly as described in the first aspect, wherein: one end of the first adhesive element is bonded to the housing assembly, the other end of the first adhesive element is bonded to the first middle frame, one end of the conductive element is connected to the conductive portion, and the other end of the conductive element is connected to the first middle frame.

[0013] In this embodiment, the first adhesive can improve the stability of the connection between the housing assembly and the first middle frame. When static charge is generated in the housing assembly, the static charge can be conducted to the first middle frame through the conductive part and the conductive component, so as to prevent the charge from being directly released to the nearest electronic device and reduce the probability of electronic devices in the electronic device burning out.

[0014] Thirdly, this application also provides a support assembly. The support assembly includes: a support plate and a conductive portion; the support plate includes a bent portion and a fixing portion disposed on both sides of the bent portion, the fixing portion includes a first surface and a second surface disposed opposite to each other, the fixing portion has carbon fiber filaments inside, and a portion of the carbon fiber filaments is exposed on the first surface of the fixing portion; the conductive portion is attached to the first surface of the fixing portion, and at least a portion of the conductive portion is in contact with and electrically connected to the exposed carbon fiber filaments.

[0015] In this embodiment, when the support plate accumulates static charge, the static charge can be conducted to the conductive part by the carbon fiber filament. The conductive part can then conduct the static charge to the grounding component to prevent the static charge from accumulating in the support plate. This reduces the probability that the charge in the support component will be directly released to the nearest electronic device when the support component is used in an electronic device, thus preventing the electronic device in the electronic device from burning out.

[0016] In one embodiment, a groove is provided on the first surface of the fixing part, and a portion of the carbon fiber filament is exposed in the groove; at least a portion of the conductive part is attached to the groove, and the at least a portion of the conductive part contacts and is electrically connected to the carbon fiber filament in the groove. The groove ensures that the carbon fiber filament can be exposed in the fixing part, allowing the conductive part to contact and be electrically connected to the carbon fiber filament.

[0017] In one embodiment, the support plate is formed with grooves, recesses, and / or through holes through an etching process. The area with the grooves is the fixing portion, and the area with the recesses and / or through holes is the bending portion. Alternatively, the grooves on the fixing portion can be directly formed during the fabrication of the support plate using a mold.

[0018] In one embodiment, the support assembly further includes a conductive element disposed at the end of the conductive portion away from the fixing portion, the conductive element being used to connect the conductive portion to a grounding assembly. The conductive element allows the support assembly to be directly connected to a second frame in an electronic device when applied to the device.

[0019] In one embodiment, the support assembly further includes a second adhesive member disposed on the side of the support plate opposite to the conductive portion, the second adhesive member being used to connect the support plate to the display panel. This approach can improve the integration of the support assembly, facilitating its application in flexible displays.

[0020] Fourthly, this application also provides a flexible display screen. The flexible display screen includes a display panel and the support assembly described in the third aspect. The display panel has a display surface and a non-display surface, and the surfaces of the fixing portion and the bending portion facing away from the conductive portion are bonded to the non-display surface. In this manner, the support assembly can be connected to a conductive element, and the conductive element can discharge electrostatic charges in the support assembly, thereby preventing the accumulation of charge in the flexible display screen having the support assembly.

[0021] In one embodiment, the flexible display screen further includes a second adhesive member disposed on the side of the support plate opposite to the conductive portion, the second adhesive member being used to connect the support plate to the display panel. The inclusion of a third adhesive member can improve the integration of the flexible display screen.

[0022] Fifthly, embodiments of this application also provide an electronic device. This electronic device may include a second frame, a third adhesive member, a conductive member, a folding assembly, and a flexible display screen (fourth aspect). The folding assembly is connected between two of the second frames. One end of the conductive member is connected to the conductive portion, and the other end of the conductive member is connected to the second frame. One end of the third adhesive member is connected to the conductive portion, and the other end of the third adhesive member is connected to the second frame. The two second frames can be relatively unfolded or folded relative to each other via the folding assembly. This electronic device does not accumulate electrostatic charge, thus reducing the probability of electronic components burning out.

[0023] In one embodiment, the electronic device further includes the housing assembly from the first aspect, the housing assembly being connected to the side of the second mid-frame opposite to the flexible display screen. In this configuration, electrostatic charges generated in both the housing assembly and the support components of the flexible display screen can be discharged through the second mid-frame.

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0042] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more” unless the context clearly indicates otherwise.

[0043] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0044] With societal progress, the types of electronic devices have diversified. These include mobile phones, tablets, and laptops, among others. Mobile phones, tablets, and laptops can be categorized as either foldable or candybar-style. Foldable electronic devices can be folded more than once, meaning they can be either two-fold or three-fold. High-performance composite materials, such as carbon fiber and ceramic composites, are also widely used in electronic devices. In one application, carbon fiber can be used in the support components of electronic devices; in another, it can be used in the outer casing. These two applications will be discussed in detail below.

[0045] Figure 1 A schematic diagram of the structure of an electronic device provided in an embodiment of this application; Figure 2 This is another structural schematic diagram of the electronic device provided in an embodiment of this application. (Refer to...) Figure 1 and Figure 2The electronic device 100 may include a first frame 10, a first adhesive member 20, conductive members 30a and 30b, a flexible display screen 40, and a housing assembly 50. The housing assembly 50 has a conductive portion 51 on the side facing the first frame. The first frame 10 has a first surface and a second surface disposed opposite to each other. The flexible display screen 40 is disposed on the first surface of the first frame 10. A conductive member 30b may be disposed between the flexible display screen 40 and the first surface of the first frame 10, connecting the flexible display screen 40 and the first frame 10. A first adhesive member 20 may be disposed between the second surface of the first frame 10 and the housing assembly 50, bonding the second surface of the first frame 10 to the housing assembly 50 to ensure that the first frame 10 is disposed within the housing assembly 50. Additionally, a conductive element 30a may be provided between the housing assembly 50 and the first middle frame 10. The conductive element 30a connects the conductive portion 51 in the housing assembly 50 to the second surface of the first middle frame 10. Thus, when electrostatic charge accumulates in the housing assembly 50, the electrostatic charge can be conducted to the first middle frame 10 through the conductive portion 51, preventing the charge from being directly released to the nearest electronic device, reducing the probability of burn-out of the electronic device 100, and improving the operational stability of the electronic device 100. The conductive elements 30a and 30b may include hollow foam and conductive materials disposed within the hollow foam, such as conductive adhesive or conductive metal. In some other embodiments, the flexible display screen 40 included in the electronic device 100 may be replaced with a non-flexible display screen, which may also include the following support components.

[0046] In some embodiments, the electronic device 100 may further include multiple components (not shown in the figures). These components may include, for example, a processor, internal memory, an external memory interface, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a communication module, a camera, an audio module, a speaker, a receiver, a microphone, a headphone jack, a sensor module, buttons, a motor, an indicator, and a subscriber identification module (SIM) card interface, etc.

[0047] The processor may include one or more processing units, such as application processors (APs), modem processors, graphics processing units (GPUs), image signal processors (ISPs), controllers, video codecs, digital signal processors (DSPs), baseband processors, and / or neural network processing units (NPUs). Different processing units may be independent devices or integrated into one or more processors.

[0048] Figure 3 This is a schematic diagram of a housing assembly provided in an embodiment of this application. (Refer to...) Figure 2 and Figure 3 The housing assembly 50 includes a housing body 53, a conductive portion 51, and a shielding portion 52. The housing body 53 has a first surface and a second surface disposed opposite to each other, with the first surface facing the first middle frame 10. The conductive portion 51 and the shielding portion 52 are disposed on the first surface of the housing body 53. Specifically, the conductive portion 51 can be disposed on the first surface by PVD (physical vapor deposition) or printing process, and the shielding portion 52 can be disposed on the first surface by printing process or spray painting. The housing body 53 includes an insulating layer 530 and carbon sheets 531. The carbon sheets 531 include carbon fiber filaments and are embedded in the insulating layer 530. At least some of the adjacent carbon sheets 531 have gaps between them, and along the thickness direction of the insulating layer 530, the gaps at least partially overlap. The multiple overlapping gaps can form a light-transmitting area 532, so that the housing body 53 includes a light-transmitting area 532. The insulating layer 530 can be made of resin, and the resin is transparent. Therefore, the carbon sheets 531 disposed in the resin (insulating layer 530) can be observed. When there is a gap between two adjacent carbon sheets 531, and the gap is connected along the thickness direction of the resin, a transparent area will be formed on the resin, that is, a light-transmitting area 532 will be formed on the insulating layer 530. The shape of the carbon sheets 531 can be rhomboid, rectangular, or circular, etc. In addition, the number of carbon sheets 531 in the resin can be adjusted according to actual needs, and no specific limitation is made here.

[0049] Understandably, the resin can be in film form, and carbon sheets 531 can be distributed on the cured film resin. The carbon sheets and resin are forged and pressed together under high temperature and pressure to form a carbon fiber composite material, also known as forged carbon. This composite material can be formed into a sheet through machining. Then, the sheet is processed to the required thickness and shape using CNC machining or grinding processes. This sheet is the aforementioned shell body 53. Specifically, in the formed shell body 53, carbon fiber filaments are exposed on the shell body 53, meaning the first surface of the shell body 53 naturally exposes the carbon fiber filaments. Alternatively, the first surface of the prepared shell body 53 is processed so that at least a portion of the carbon fiber filaments in the insulating layer 530 are exposed on the first surface of the shell body 53. A conductive part 51 is disposed on the first surface of the shell body 53. The conductive part 51 can contact and electrically connect with the exposed carbon fiber filaments, and the charge is discharged through a conductive member 30a connected to the conductive part 51 and located on the side opposite to the shell body 53. In this manner, static charge in the shell body 53 can be discharged by the carbon fiber filaments, preventing the accumulation of static charge in the shell body 53. This can reduce the probability that when the housing assembly 50 is used in the electronic device 100, the charge in the housing assembly 50 is directly released to the nearest electronic device, causing the electronic device in the electronic device to burn out.

[0050] Furthermore, since the housing body 53 has a light-transmitting area 532, the light-transmitting area 532 affects the appearance of the entire housing assembly 50, causing the housing assembly 50 to have light spots. Moreover, when the housing assembly 50 is applied to the electronic device 100, the light-transmitting area 532 also affects the appearance of the electronic device 100. Therefore, the housing assembly 50 in this embodiment further includes the aforementioned shielding portion 52. The shielding portion 52 and the conductive portion 51 are disposed on the first surface of the housing body 53. The shielding portion 52 at least partially covers the light-transmitting area 532 in the projection of the housing body 53, which can prevent or reduce the light transmission of the light-transmitting area 532, thereby preventing or reducing the light transmittance in the housing assembly 50.

[0051] There are various positional relationships between the shielding part 52 and the conductive part 51 located on the first surface of the shell body 90. Figure 4a This is another structural schematic diagram of the shell body in the shell assembly provided in this application embodiment. (Refer to...) Figure 4a A portion of the first surface of the shell body 53 is provided with a shielding part 52. The projection of the shielding part 52 on the first surface covers the projection portion of the light-transmitting area 532 of the shell body 53 on the first surface. At least a portion of the carbon fiber filaments are exposed in the uncoated portion of the first surface. A conductive part 51 is disposed in the uncoated portion of the first surface and contacts and is electrically connected to the exposed portion of the carbon fiber filaments to ensure that the charge in the shell body 53 can be released and to prevent the accumulation of static charge. In some other embodiments, Figure 4b This is another structural schematic diagram of the shell body in the shell assembly provided in the embodiments of this application, referred to... Figure 4b A shielding part 52 is provided on the first surface of the shell body 53. The projection of the shielding part 52 on the first surface completely covers the projection of the light-transmitting area 532 of the shell body 53 on the first surface. At least part of the carbon fiber filaments are exposed on the part of the first surface that is not coated by the shielding part. The conductive part 51 is provided on the part of the first surface that is not coated by the shielding part 52 and contacts and is electrically connected to the carbon fiber filaments exposed on the part of the first surface that is not coated by the shielding part. In this way, the shell assembly 50 will not be light-transmitting.

[0052] The shielding portion 52 may include a paint layer, which can be black or other dark colors, to prevent light from passing through the light-transmitting area 532. The number of paint layers can be adjusted according to actual needs. Specifically, when applying the paint layer to the first surface of the shell body 53, a baffle can be pre-set on the first surface of the shell body 53 (at least part of the carbon fiber filaments are exposed in the area corresponding to the baffle and the shell body 53; the location of the baffle can be understood as the paint layer). The paint layer is applied to the first surface of the shell body using a printing process, and then the baffle is removed. If there is a light-transmitting area in this region, the paint layer can be applied to the first surface of the shell body 53 by dotting or spraying, so that the shielding portion completely covers the light-transmitting area. If the shielding portion at least partially covers the light-transmitting area, the paint layer may not be required at this location. Metal is sputtered onto the area of ​​the baffle using a PVD process to form a conductive portion 51. In this case, the conductive portion 51 and the shielding portion 52 can be located in the same plane. Alternatively, the conductive portion 51 can be a silver paste layer, which can be applied to the portion of the first surface not coated with a paint layer using a printing process. The silver paste layer can be pure silver paste or silver paste mixed with different colors.

[0053] Figure 5a This is another structural schematic diagram of the shell body in the shell assembly provided in this application embodiment. (Refer to...) Figure 5aThe shielding portion 52 is coated on the first surface of the shell body 53. The shielding portion 52 is correspondingly disposed with respect to the light-transmitting area 532, and the projection of the shielding portion 52 on the first surface of the shell body 53 completely covers the projection of the light-transmitting area 532 on the first surface. At this time, the shielding portion 52 may include multiple pieces, and each shielding portion 52 corresponds to at least one light-transmitting area 532. The shielding portion 52 includes a paint layer, and the color of the paint layer can be black or other dark colors to prevent light from passing through the light-transmitting area 532. The number of paint layers can be adjusted according to actual needs. The paint layer can be formed by dotting or spraying. Alternatively, the shielding portion 52 may include a metal sheet or plastic sheet with black, blue or other dark colors, and each metal sheet or plastic sheet is bonded to the shell body 53 corresponding to the light-transmitting area 532. In this case, the conductive portion 51 can be disposed on the side of the shielding portion 52 away from the shell body 53. Since the shielding portion 52 only shields the part of the shell body 53 with the light-transmitting area 532, part of the conductive portion 51 can contact and electrically connect with the exposed carbon fiber filaments. In this configuration, the conductive part 51 can completely cover the shielding part, meaning the shielding part 52 is positioned between the conductive part 51 and the shell body 53. The conductive part 51 can be a silver paste layer, applied to the first surface of the shell body via a printing process, covering the shielding part 92 during the application. Alternatively, the conductive part 51 can be a metal layer, deposited on the first surface of the shell body via physical vapor deposition, also covering the shielding part.

[0054] Figure 5b This is another structural schematic diagram of the shell body in the shell assembly provided in this application embodiment. (Refer to...) Figure 5a When the conductive part 51 is disposed on the shielding part 52 away from the first surface, the projection of the shielding part 52 on the shell body 53 completely covers the light-transmitting area 532. At this time, the shielding part 52 may include multiple parts, and at least one light-transmitting area 532 does not correspond to the shielding part 52.

[0055] In the above embodiments, the conductive part 51 can be made of one or a mixture of nickel, chromium, silver or copper. In addition, the conductive part 51 can also include multiple layers, and the material used for each layer can be different.

[0056] Figure 6 This is another structural schematic diagram of the shell body in the shell assembly provided in this application embodiment. (Refer to...) Figure 6The housing assembly 50 further includes a conductive element 30a, which is used to electrically connect the conductive part 51 to the first middle frame 10. This ensures that when the housing assembly 50 is applied to the electronic device 100, the charge generated in the housing body 53 can be conducted to the first middle frame 10 through the conductive part 51 and the conductive element 30a for release, preventing damage to the components in the electronic device. The housing assembly 50 may also include a first adhesive element 20, which is used to connect the conductive part 51 and / or the shielding part 52 to the first middle frame 10, ensuring that the housing assembly 50 can be stably disposed in the electronic device 100.

[0057] Figure 7 This is a schematic diagram of an electronic device in an unfolded state, as provided in an embodiment of this application. Figure 8 This is a schematic diagram of an electronic device in a folded state, as provided in an embodiment of this application. Figure 7 for Figure 8 The folded state of electronic devices. (Refer to...) Figure 7 and Figure 8 The electronic device provided in this application is a foldable electronic device 100. Specifically, the electronic device 100 may include a flexible display screen 40, two second mid-frames 60, and a folding assembly 70. The flexible display screen 40 is connected to the two second mid-frames 60, and the folding assembly 70 is connected to the two second mid-frames 60. The folding assembly 70 is used to unfold or fold the two second mid-frames 60 relative to each other. The folding assembly 70 may be an inner folding assembly 70 or an outer folding assembly 70. An inner folding assembly 70 refers to a folding assembly 70 that can fold at least partially of the flexible display screen 40 between the two second mid-frames 60. An outer folding assembly 70 refers to a folding assembly 70 that can fold at least partially of the flexible display screen 40 outside the second mid-frames 60.

[0058] When the two second frames 60 and the folding assembly 70 are in a relatively unfolded state, the electronic device 100 is in an unfolded state. For example, when the electronic device 100 is in the unfolded state, the two second frames 60 and the folding assembly 70 can be laid flat, that is, the two second frames 60 and the folding assembly 70 can be approximately 180° apart (where approximately 180° can be understood to allow for slight deviations, such as: 175°, 178°, 182° or 184°, etc.).

[0059] Figure 9 This is another structural schematic diagram of the electronic device provided in the embodiments of this application in its unfolded state, referred to... Figure 9The electronic device 100 further includes a conductive element 30c and a third adhesive element 80; the flexible display screen 40 may include a support assembly 41 on the side facing the second middle frame 60, wherein: one end of the conductive element 30c is connected to the support assembly 41, and the other end of the conductive element 30c is connected to the second middle frame 60, the conductive element 30c is used to conduct the charge generated in the support assembly 41 to the second middle frame 60, so as to release the charge generated in the support assembly 41. The third adhesive element 80 is disposed on the side of the flexible display screen 40 facing the two second middle frames 60, and the third adhesive element 80 can fix the flexible display screen 40 to the second middle frame.

[0060] The conductive element 30c can be multiple, and a conductive element 30c can be disposed between each of the second middle frame 60 and the support component 41 in the flexible display screen 40. The conductive element 30c can also be connected to other grounding components in the electronic device 100 to conduct electrostatic charges in the support component 41, such as connecting the conductive element 30c to the ground of the flexible circuit board of the electronic device 01. The conductive element 30c may include hollow foam and conductive material disposed within the hollow foam, such as conductive adhesive or conductive metal.

[0061] The third adhesive 80 can be an insulating adhesive, which can be distributed between the edge of the second middle frame 60 and the flexible display screen 40 so that the flexible display screen 40 is bonded to the second middle frame 60.

[0062] Figure 10 This is a schematic diagram of a flexible display screen provided in an embodiment of this application. (Refer to...) Figure 9 and Figure 10 The flexible display screen 40 includes a display panel 42 and a support component 41, which are stacked together in the thickness direction of the flexible display screen 40. The display panel 42 has a display surface and a non-display surface, and the non-display surface is bonded to the support component 41. A second adhesive member 43 may be provided between the display panel 42 and the support component 41 to bond the support plate 411 of the support component 41 to the display panel 42. The side of the support component 41 facing away from the display panel 42 can be used to connect to a second middle frame 60 or to a first middle frame 10.

[0063] Figure 11 This is another structural schematic diagram of the flexible display screen provided in an embodiment of this application. Relative to... Figure 10 In other words, Figure 11 The conductive component 30c and the third adhesive component 80 have been added, as shown in the reference. Figure 11In some other embodiments, the flexible display screen 40 may further include a conductive element 30c and a third adhesive element 80. One end of the conductive element 30c is connected to the conductive portion 410 in the support assembly 41, and the other end of the conductive element 30c is used to connect to the second middle frame 60. The conductive element 30c is used to conduct the charge generated by the support plate 411 in the support assembly 41 to the second middle frame 60, thereby releasing the charge in the support assembly 41. The third adhesive element 80 is disposed on the side of the support assembly 41 facing away from the display panel 42, and is used to fix the conductive portion 410 to the second middle frame 60. The third adhesive element 80 may also be used to connect the conductive portion 410 to the first middle frame 10.

[0064] Display panel 42 is used to display images, etc. Display panel 42 can be a flexible display panel. For example, display panel 42 can be an organic light-emitting diode (OLED) display panel, an active-matrix organic light-emitting diode (AMOLED) display panel, a mini organic light-emitting diode (MLED) display panel, a micro organic light-emitting diode (MOLED) display panel, or a quantum dot light-emitting diode (QLED) display panel, etc.

[0065] For example, the flexible display screen may also include structures such as a back film (not shown), a polarizer (POL) (not shown), and a protective cover (not shown). In one embodiment, the flexible display screen may also include a touchpad (not shown).

[0066] Figure 12 A side view of a support component provided in an embodiment of this application, with reference to... Figure 9 , Figure 10 , Figure 11 and Figure 12The support assembly 41 may include a support plate 411 and a conductive portion 410. The support plate 411 includes a bent portion 4110 and a fixing portion 4111 disposed on both sides of the bent portion 4110. The fixing portion 4111 has a first surface and a second surface disposed opposite to each other, wherein the first surface is the side facing the second middle frame 60 and the second surface is the side facing the display panel. The fixing portion 4111 contains carbon fiber filaments 41110, and a portion of the carbon fiber filaments 41110 is exposed on the first surface of the fixing portion 4111. The conductive portion 410 is attached to the first surface of the fixing portion 4111, and at least a portion of the conductive portion 410 is in contact with and electrically connected to the exposed carbon fiber filaments 41110. When static charge accumulates in the support plate 411, the static charge can be conducted to the conductive part 410 through the carbon fiber filament 41110. The conductive part 410 can conduct the static charge to the grounding component to prevent the static charge from accumulating in the support plate 411. This reduces the probability that the charge in the support plate 411 will be directly released to the nearest electronic device when the support component 41 is used in electronic devices, thus preventing the electronic device in the electronic device from burning out.

[0067] Figure 13 A cross-sectional view of the central support plate of the support assembly provided in an embodiment of this application. (Refer to...) Figure 13 The number of bending portions 4110 can be one or two. When there is one bending portion 4110, the support component 41 can have one bend; when there are two bending portions 4110, the support component 41 can have two bends; the number of bending portions 4110 can also be three or four, etc. Furthermore, the hardness of the bending portion 4110 is less than the hardness of the fixing portion 4111. A transition portion 4112 can also be provided between the bending portion 4110 and the fixing portion 4111, connecting the bending portion 4110 and the fixing portion 4111. The hardness of the transition portion 4112 is greater than that of the bending portion 4110, and the hardness of the transition portion 4112 is less than that of the fixing portion 4111. In this embodiment, the different strengths of the fixing part 4111, the transition part 4112, and the bending part 4110 can be achieved by varying the number of grooves and / or through holes provided in each part. That is, the number of grooves on the fixing part 4111 is less than the number of grooves and / or through holes on the transition part 4112, and the number of grooves and / or through holes on the transition part 4112 is less than the number of grooves and / or through holes on the bending part 4110. Alternatively, the strength of the fixing part 4111, the transition part 4112, and the bending part 4110 can also be controlled by controlling the size of the grooves and / or through holes. The quantities and sizes mentioned here refer to the size and number of grooves and / or through holes per unit area.

[0068] Figure 14 This application provides another structural schematic diagram of the support plate 411. (Refer to...) Figure 14The support plate 411 may include an insulating layer 4113 and carbon fiber filaments 41110 embedded in the insulating layer, wherein the carbon fiber filaments 41110 may be arranged alternately in the horizontal direction X and the vertical direction Y. Figure 8 The spacing between the carbon fiber filaments 41110 in the diagram is not the actual spacing between the carbon fiber filaments 41110 in the support plate 411; it merely represents a schematic diagram of the distribution of the carbon fiber filaments 41110. The actual density of the carbon fiber filaments 41110 in the support plate 411 is much greater than that in the diagram. Figure 8 The density is illustrated in the diagram. During the preparation process of carbon fiber filaments 41110 and insulation layer 4113 (matrix resin, specifically epoxy resin, phenolic resin, or thermoplastic resin) through a single-layer prepreg or multi-layer prepreg stacking and then compression molding, the carbon fiber filaments 41110 overlap, twist, and twist with each other, allowing them to conduct electricity to each other. Simultaneously, due to the relatively high density of the carbon fiber filaments 41110, the spacing between them is small. When the support plate includes multiple insulation layers 4113, indirect coupling can exist between the carbon fiber filaments 41110 of each insulation layer 4113, thus enabling them to conduct electricity to each other.

[0069] Among them, the carbon fiber filaments 41110 can be naturally exposed on the support plate 411. That is, during the molding process, some of the carbon fiber filaments 41110 are exposed on the side of the insulating layer 4113 facing the second middle frame, so that the conductive part can contact and electrically connect with the carbon fiber filaments 41110.

[0070] In one embodiment, Figure 15 A cross-sectional view of the fixing portion in a support plate is provided for an embodiment of this application. (Refer to...) Figure 15The exposed support plate 411 has carbon fiber filaments 41110 that are artificially formed groove structures. Specifically, the first surface of the fixing part 4111 (the side facing the second middle frame) can be provided with a groove 41111, and part of the carbon fiber filaments 41110 is exposed in the groove 41111. There can be multiple grooves 41111, and these grooves 41111 can be unevenly distributed on the first surface of the fixing part 4111. Creating the groove 41111 on the first surface of the fixing part 4111 actually means creating the groove 41111 on the surface of the support plate (the side facing the second middle frame 60 and the first middle frame 10). The groove 41111 can be created using mechanical equipment through CNC (computer numerical control), polishing, grinding, wire drawing, or other processes, or it can be created on the side of the support plate facing the second middle frame using ion beam etching or photolithography. Furthermore, the formation of the groove 41111 on the side of the support plate facing the second middle frame can be different through different processes. This application does not specifically limit the shape of the groove 41111 on the first surface of the fixing part 4111.

[0071] It is worth mentioning that, since the support plate also includes a bent portion, while the groove is opened on the first surface of the fixing portion through the above process, a recess and / or through hole can also be formed on the part of the support plate corresponding to the bent portion.

[0072] The groove 41111 on the first surface of the fixing part 4111 may include a bottom wall 41111b and a side wall 41111a, which together form a receiving space. The exposed portion of the carbon fiber filament 41110 can extend into the receiving space through one of the side walls 41111a; and / or, the exposed portion of the carbon fiber filament 41110 can also extend into the receiving space through multiple side walls 41111a; and / or, the exposed portion of the carbon fiber filament 41110 can also extend into the receiving space through the bottom wall 41111b. Specifically, the carbon fiber filament 41110 simply needs to be located within the receiving space of the groove 41111. In some other embodiments, the bottom wall 41111b and the side wall 41111a can be planar or curved.

[0073] When the first surface of the fixing part 4111 has a groove 41111, at least a portion of the conductive part 410 can be located in the groove 41111 to ensure that the conductive part can contact and electrically connect with the carbon fiber filament 41110 exposed in the groove 41111. The conductive part 410 can cover the first surface of the fixing part 4111, and in the projection of the fixing part 4111, the conductive part can at least partially cover the carbon fiber filament 41110 exposed in the groove 41111.

[0074] Specifically, the conductive portion can be attached to the first surface of the fixed portion via PVD sputtering. Specifically, plasma bombardment of a metal target causes target atoms to be sputtered and deposited onto the first surface of the fixed portion to form the conductive portion. Thus, the connection between the first surface of the fixed portion 4111 and the conductive portion 410 can be understood as an atomic-level connection, thereby improving the stability of the connection between the fixed portion 4111 and the conductive portion 410. When the support assembly is applied to an electronic device, refer to... Figure 9 , Figure 10 , Figure 11 and Figure 12 The end of the support component 41 facing away from the display panel 42 may also have a third adhesive member 80, and is connected to the second middle frame 60 through the third adhesive member 80. The other end of the support component 41 is connected to the display panel 42. When the support component 41 and the second middle frame 60 need to be separated, the third adhesive member 80 will apply a pulling force to the conductive part 410. Since the conductive part 410 is fixed to the fixing part 4111 of the support plate 411 by the PVD process, the stability of the connection between the conductive part 410 and the fixing part 4111 is greater than the adhesive force between the third adhesive member 80 and the conductive part 410. This ensures that when the support component 41 is disassembled from the second middle frame 60, the conductive part 410 will not separate from the fixing part 4111, which can improve the stability of the support component 41 itself, thereby improving the stability of the flexible display screen 40 with the support component 41 and reducing the scrap rate of the flexible display screen 40 when disassembled from the second middle frame 60. Similarly, when the flexible display screen 40 with the support component 41 is disposed on the first middle frame 10, the scrap rate of the flexible display screen 40 after being removed from the first middle frame 10 can also be reduced.

[0075] The conductive part 410 may be made of one or a mixture of nickel, chromium, silver, or copper. In some embodiments, the conductive part 410 may include a first layer and a second layer, which are stacked together, wherein the materials of the first layer and the second layer may be different. The conductive part 410 may also include a third layer or a fourth layer, which will not be described in detail here.

[0076] In some embodiments, the support assembly 41 may further include the aforementioned second adhesive member 43, which is disposed on the side of the support plate 411 opposite to the conductive portion 410. There may be multiple second adhesive members 43, which may be evenly distributed on the fixing portion 4111 and the bending portion 4110, or the second adhesive member 43 may be coated on the side of the fixing portion 4111 opposite to the conductive portion 410.

[0077] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
