[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on March 21, 2024, with application number 202410332543.7 and invention name “Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic devices, and more particularly, to an electronic device. Background Art

[0003] With the continuous development of electronic devices, electronic devices with displays (such as mobile phones and tablets) have become an indispensable part of people's daily lives and work. To optimize performance, the display screens on electronic devices are often grounded. This means that the display screen is electrically connected to metal components within the device (such as the shielding case) to form a ground path, thereby achieving grounding for the display screen.

[0004] Currently, conductive foam is commonly used to achieve electrical connections in displays. However, this requires a large working height and contact area, significantly impacting the overall thickness of the device and the space required for component layout. Furthermore, the conductive foam is compressed during operation, generating a significant force against the screen. This increases the risk of film printing and debonding on the display, impacting screen reliability.

[0005] Therefore, there is an urgent need to provide a display screen electrical connection solution that can reduce the thickness of the entire device while improving the reliability of the screen and the device layout space within the electronic device. Summary of the Invention

[0095] Figures 1 and 2 are schematic structural diagrams of an electronic device 100 provided in an embodiment of the present application, wherein Figure 1 is an assembled schematic diagram of the electronic device 100, and Figure 2 is an exploded schematic diagram of the electronic device 100.

[0096] In the embodiments of the present application, the electronic device 100 may be a mobile phone, tablet computer, smart watch, e-reader, laptop computer, wearable device, camera, car computer, smart screen, or other electronic device with a display function. The embodiments of the present application do not impose any particular restrictions on the specific form of the electronic device 100. For ease of explanation and understanding, the following description takes the electronic device 100 as an example of a foldable mobile phone.

[0097] For the convenience of description, the following definition defines the direction parallel to the folding axis of the electronic device 100 as the X direction, the direction parallel to the screen and perpendicular to the folding axis of the electronic device 100 when the electronic device 100 is in the unfolded state as the Y direction, and the direction perpendicular to the screen when the electronic device 100 is in the unfolded state as the Z direction, which is perpendicular to the X direction and perpendicular to the Y direction. The definitions of the X, Y, and Z directions here also apply to the various drawings to be described later. It should be noted that the above definitions of the X, Y, and Z directions are only for the convenience of describing the positional relationship and connection relationship between the various components in the embodiments of the present application, and should not be understood as limiting the embodiments of the present application.

[0098] Referring to Figures 1 and 2 , electronic device 100 may include a flexible screen 110 and a housing 120. Housing 120 defines a storage space for accommodating various components of electronic device 100. Flexible screen 110 is disposed within the storage space formed by housing 120 and is connected to housing 120. Housing 120 also serves to protect electronic device 100 and support the entire device.

[0099] The flexible screen 110 is used to display images. In Figures 1 and 2, the flexible screen 110 is schematically represented by a structure filled with a dot matrix pattern. The flexible screen 110 has the characteristics of strong flexibility and bendability, and can provide users with a new interaction method based on its bendable characteristics. The display panel of the flexible screen 110 can adopt any one of, for example, a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light emitting diode or an active-matrix organic light emitting diode (AMOLED), a flexible light-emitting diode (FLED), a quantum dot light emitting diode (QLED), etc., and the embodiments of the present application are not limited to this.

[0100] In the embodiment of the present application, the flexible screen 110 has a light-emitting surface capable of displaying images. The side surface of the flexible screen 110 opposite the light-emitting surface can be referred to as the back surface of the flexible screen 110. The back surface of the flexible screen 110 is accommodated in the accommodation space formed by the housing 120 and is not visible to the user.

[0101] The housing 120 may include a first housing 121 and a second housing 122, and the first housing 121 and the second housing 122 may rotate relative to each other about a folding axis 1301 of the electronic device 100. For example, the first housing 121 may rotate relative to the second housing 122 about the folding axis 1301, and / or the second housing 122 may rotate relative to the first housing 121 about the folding axis 1301, so that the electronic device 100 can be converted between a folded state and an open state.

[0102] In some embodiments, the electronic device 100 may further include a hinge mechanism 130, which is used to connect the first housing 121 and the second housing 122 to enable the first housing 121 and the second housing 122 to rotate relative to each other around a folding axis 1301. Accordingly, the electronic components provided on the first housing 121 or the electronic components provided on the second housing 122 can rotate around the folding axis 1301.

[0103] Because the first housing 121 and the second housing 122 are hingedly connected by the hinge mechanism 130, the first housing 121 and the second housing 122 can be in a stacked state or in an unfolded state with an angle between them. For example, when the electronic device 100 is folded, the angle between the first housing 121 and the second housing 122 can be close to 0°. For another example, when the electronic device 100 is unfolded, the angle between the first housing 121 and the second housing 122 can be close to 180°.

[0104] In one example, the hinge mechanism 130 may include a main shaft, a first connecting component, and a second connecting component. The first connecting component may be fixed to the first housing 121, and the second connecting component may be fixed to the second housing 122. The first and second connecting components are rotatable relative to the main shaft. The mutual movement of the first and second connecting components can drive the mutual movement of the first and second housings 121, 122, thereby realizing the opening and closing function of the electronic device 100.

[0105] In some embodiments, as shown in FIG2 , the housing 120 may include a middle frame 123 . The middle frame 123 is a support frame located inside the electronic device 100 . The middle frame 123 is generally formed of a metal material such as copper, magnesium alloy, stainless steel, etc. In an embodiment of the present application, the middle frame 123 can be used to support and fix the flexible screen 110 . For example, as shown in FIG2 , the flexible screen 110 (specifically, the back of the flexible screen 110 ) can be bonded to the middle frame 123 by an adhesive 150 .

[0106] In some embodiments, as shown in FIG2 , the housing 120 may include a frame 124. The frame 124 is a structure surrounding the periphery of the electronic device 100. For example, the frame 124 may be provided around the periphery of the flexible screen 110 to help secure the flexible screen 110. For example, the frame 124 may be provided around the periphery of the middle frame 123, and the frame 124 is connected to the middle frame 123. The frame 124 may be made of metal, such as copper, magnesium alloy, stainless steel, etc., or may be made of non-metallic materials, such as plastic, glass, ceramic, etc.

[0107] In some embodiments, as shown in FIG2 , the housing 120 may include a back cover 125 . The back cover 125 is typically located on the back of the electronic device 100 . For example, the back cover 125 is located on the side of the middle frame 123 facing away from the flexible screen 110 . The back cover 125 is primarily used to protect components and batteries within the electronic device 100 . For example, the back cover 125 can prevent external impurities such as dust and water from entering the phone. In some embodiments, the back cover 125 can also be used to secure other display screens besides the flexible screen 110 or to secure antennas.

[0108] In some embodiments, the middle frame 123, the frame 124, and the back cover 125 may be three parts of the housing 120 of the electronic device 100. That is, the middle frame 123 and the frame 124 may be connected, and the frame 124 and the back cover 125 may be connected, wherein the connection forms include but are not limited to snap-fitting, bonding, welding, riveting, clearance fitting, and other detachable or non-detachable connection methods. In other embodiments, the frame 124 and the middle frame 123 may be an integrated structure (or an integrated molded structure); or, the frame 124 and the back cover 125 may be an integrated structure.

[0109] In some embodiments, as shown in Figure 2, the middle frame 123 may include a first middle frame portion 1231 and a second middle frame portion 1232 arranged along a direction perpendicular to the folding axis 1301 (the Y direction as shown in Figure 2), wherein the first middle frame portion 1231 and the second middle frame portion 1232 are respectively located on both sides of the folding axis 1301.

[0110] In some embodiments, the frame 124 may include a first frame portion 1241 and a second frame portion 1242 arranged along a direction perpendicular to the folding axis 1301 (the Y direction as shown in Figure 2), wherein the first frame portion 1241 and the second frame portion 1242 are respectively located on both sides of the folding axis 1301.

[0111] In some embodiments, the back cover 125 may include a first back cover portion 1251 and a second back cover portion 1252 arranged along a direction perpendicular to the folding axis 1301 (the Y direction as shown in Figure 2), wherein the first back cover portion 1251 and the second back cover portion 1252 are respectively located on both sides of the folding axis 1301.

[0112] In an embodiment of the present application, at least part of the first middle frame portion 1231, the second middle frame portion 1232, the first border portion 1241, the second border portion 1242, the first back cover portion 1251 and the second back cover portion 1252 can form a first shell 121 and a second shell 122 for supporting the flexible screen 110.

[0113] For example, the first housing 121 may include a first middle frame portion 1231, a first frame portion 1241, and a first back cover portion 1251, and the second housing 122 may include a second middle frame portion 1232, a second frame portion 1242, and a second back cover portion 1252. The first middle frame portion 1231, the first frame portion 1241, and the first back cover portion 1251 are located on the same side of the folding axis 1301, and the second middle frame portion 1232, the second frame portion 1242, and the second back cover portion 1252 are located on the same side of the folding axis 1301.

[0114] In some embodiments, the flexible screen 110 may include a first display portion 111 corresponding to the first housing 121, a second display portion 112 corresponding to the second housing 122, and a third display portion 113 corresponding to the hinge mechanism 130. The third display portion 113 is located between the first display portion 111 and the second display portion 112 and is a foldable display portion. For example, the first display portion 111 is fixed to the first housing 121, the second display portion 112 is fixed to the second housing 122, and the third display portion 113 is fixed to the hinge mechanism 130. Under the action of the hinge mechanism 130, the first housing 121 and the second housing 122 can move closer to or farther away from each other. Accordingly, the first display portion 111 and the second display portion 112 can move closer to or farther away from each other, and the third display portion 113 will bend, allowing the flexible screen 110 to be folded or unfolded.

[0115] As shown in reference figure 2, the electronic device 100 also includes a circuit board 140, which is accommodated in the accommodating space formed by the shell 120 and is connected to the shell 120 (such as the middle frame 123). The circuit board 140 has the function of supporting circuit elements and interconnecting circuit elements. Specifically, the circuit board 140 is a support body for electronic components and a carrier for electrical connection of electronic components. The electronic components provided on the circuit board 140 include but are not limited to capacitors, inductors, resistors, shielding covers, processors, memories, connectors, cameras, flashes, microphones, batteries, antennas, etc. In some embodiments, a circuit board integrated with electronic components (such as a processor, a radio frequency chip, a board-to-board connector, a controller or an external interface, etc.) can be called a motherboard.

[0116] In some embodiments, the circuit board 140 may include a first circuit board (or first main board) 141 and a second circuit board (or second main board) 142. The first circuit board 141 and the second circuit board 142 are respectively located on both sides of the folding axis 1301. For example, the first circuit board 141 is accommodated in the accommodation space formed by the first shell 121 and the first display unit 111, and the second circuit board 142 is accommodated in the accommodation space formed by the second shell 122 and the second display unit 112.

[0117] In the embodiment of the present application, the electronic device 100 can switch between a folded state and an unfolded state. When the electronic device 100 is in the folded state, the space occupied by the electronic device 100 is relatively small; when the electronic device 100 is in the unfolded state, the electronic device 100 can display a relatively large screen to increase the user's viewing range.

[0118] Illustratively, the electronic device 100 shown in FIG1 is in an unfolded state, and accordingly, the flexible screen 110 is in an unfolded state, and the first display portion 111 and the second display portion 112 are located on the same plane, which can facilitate users to use the large screen.

[0119] For example, FIG3 shows two possible folded states of the electronic device 100. In the embodiment of the present application, the electronic device 100 being in the folded state may mean that the electronic device 100 is currently bent and the degree of bending of the electronic device 100 has reached the maximum. In this case, the first display portion 111 and the second display portion 112 can be considered to be located on different planes.

[0120] (a) in FIG3 shows a state in which the screen of the electronic device 100 is folded outward, i.e., in the outward folded state. In the outward folded state, the first display portion 111, the second display portion 112, and the third display portion 113 can form a housing area for accommodating the first shell 121, the second shell 122, and the hinge mechanism 130. In other words, the first shell 121, the second shell 122, and the hinge mechanism 130 can be accommodated in the interval space between the first display portion 111 and the second display portion 112. At this time, the first display portion 111 and the second display portion 112 are facing each other, the first shell 121 and the second shell 122 are opposite each other, and the third display portion 113 is bent.

[0121] (b) in Figure 3 shows the state where the screen of the electronic device 100 is folded inward, that is, the inward folded state. In the inward folded state, the first shell 121, the second shell 122 and the hinge mechanism 130 can form a screen area for accommodating the flexible screen 110. In other words, the flexible screen 110 can be accommodated in the space between the first shell 121 and the second shell 122. At this time, the first display portion 111 and the second display portion 112 are opposite to each other, the first shell 121 and the second shell 122 are facing away from each other, and the third display portion 113 is bent.

[0122] In some embodiments, when the flexible screen 110 is an inward folding screen, the electronic device 100 may further include an external screen 160. The external screen 160 is generally disposed on one side of the back cover 125, opposite to the non-bending area of ​​the flexible screen 110 (such as the first display portion 111 or the second display portion 112). For example, the external screen 160 may be disposed on the front of the electronic device 100 when it is in a folded state. The external screen 160 may be used to display user interfaces, applications, images, videos, notifications, or information that facilitates daily operations or viewing by the user. In some embodiments, the external screen 160 may have a touch function to facilitate user interaction with the electronic device 100 through the external screen 160. The external screen 160 (specifically, the back of the external screen 160) may be adhered to the middle frame 123 by an adhesive 150. Generally, the external screen 160 includes a glass cover plate, which is disposed on the outermost side of the light-emitting surface of the external screen 160.

[0123] In some embodiments, the flexible screen 110 may also be referred to as a main screen or a folding screen, and the external screen 160 may also be referred to as a secondary screen or a front screen. In the embodiments of the present application, the flexible screen 110 and the external screen 160 are collectively referred to as display screens. In the following embodiments, if the electronic device 100 includes multiple display screens, the different display screens are distinguished by the corresponding terms "first display screen," "second display screen," and so on.

[0124] It should be understood that Figures 1 to 3 only schematically illustrate that the electronic device 100 includes two foldable parts (a first shell 121 and a second shell 122), that is, the electronic device 100 has a folding axis. In some other embodiments, the electronic device 100 may also include three or more foldable parts. Accordingly, the electronic device 100 has two or more folding axes, such as a two-fold mobile phone, a three-fold mobile phone, and a multi-fold mobile phone, so that the user can fold it multiple times along multiple folding axes. As the number of foldable parts of the electronic device 100 increases, while maintaining the same screen size in the unfolded state, the occupied space of the electronic device 100 can be further reduced in the folded state; or while occupying the same space in the folded state, the displayed screen area can be further enlarged in the unfolded state.

[0125] It should also be understood that Figures 1 to 3 only schematically illustrate some components included in the electronic device 100, and the shape, size, and structure of these components are not limited by Figures 1 to 3. In some other embodiments, the electronic device 100 may also include more or fewer components than shown in the figure, and the embodiments of the present application are not limited thereto. In other embodiments, the type of electronic device 100 is different, and the components included in the electronic device 100 are different. For example, the electronic device 100 may also be a side-sliding mobile phone, a straight-screen phone, etc. The foldable mobile phone structure provided in the embodiments of the present application is only for illustrative purposes.

[0126] For performance optimization, displays on electronic devices are often grounded. This means the display is electrically connected to metal components within the device (such as the midframe, motherboard bracket, and shielding case), creating a return path to ground the display. For example, users of electronic devices often carry static electricity. Upon touching the device, this static electricity can strike the display, causing electrostatic discharge (ESD). To improve the display's anti-static capabilities, the display is often grounded. For another example, when a display is operating normally, its electronic components (such as light-emitting diodes and semiconductors) accumulate charge. Alternatively, when an electronic device is dropped and rubbed against an object, static electricity is generated, which gradually accumulates on the display. Excessive charge accumulation on the display can affect its normal operation, such as causing problems such as light rings or light leakage in localized areas of the display. Grounding the display can transfer excess charge, preventing excessive charge accumulation from affecting the display's performance. For example, if an antenna is installed between two oppositely arranged display screens (such as the aforementioned flexible screen 110 and the outer screen 160), the charge on the display screen will cause antenna clutter problems, such as radiated spurious emission (RSE). Grounding at least one display screen can transfer the charge on the display screen, which is beneficial to improving the radio frequency performance of the electronic device.

[0127] Currently, conductive foam is commonly used to achieve electrical connections for display screens. Conductive foam is a foam material with conductive properties. The principle is to mix a filler with good conductivity, such as carbon fiber and copper powder, into the foam material to make the foam material conductive. However, conductive foam requires a large working height and contact area. For example, to solve the problem of film printing on the display screen, conventional designs often use conductive foam with an initial height of 1.5mm and a working height of 0.5mm-0.8mm. For another example, to avoid RSE problems, conductive foam has a minimum design area requirement (such as a contact area of ​​2.5mm*6.5mm). However, multiple conductive foams are usually required in electronic devices, which seriously affects the thickness of the entire device and the space for device layout. In addition, the conductive foam is compressed during operation. Each piece of conductive foam exerts a top-screen force of about 1 Newton (symbolized by N) on the display screen. The more conductive foam there is, the greater the top-screen force, the greater the risk of film printing on the display screen and the risk of screen debonding, which affects the reliability of the screen.

[0128] For ease of understanding, FIG4 shows, by way of example, a schematic diagram of a display screen electrical connection solution using conductive foam.

[0129] As shown in Figure 4 (a), in one solution, conductive foam can be placed between the motherboard bracket (which typically has one or more of the following functions: press-fit board-to-board connector, laser antenna for laser direct structuring (LDS), load-bearing components, reinforcement, etc., and is generally made of or includes metal) and the display screen. The ends of the conductive foam abut the motherboard bracket and the display screen, respectively, to achieve electrical connection to the display screen. However, this solution has high requirements for the thickness of the entire device. Specifically, the motherboard bracket is usually arranged between the motherboard and the display screen, where the gap between the metal surface of the motherboard bracket and the devices on the motherboard needs to be more than 0.2mm, the metal wall thickness of the motherboard bracket needs to be more than 0.2mm, and the working height of the conductive foam needs to be more than 0.5mm. When the selection of various components is consistent, when conductive foam is used to electrically connect the motherboard bracket and the display screen, the height dimension from the motherboard to the display screen needs to increase the internal cavity space of the entire machine by more than 0.9mm, where 0.9mm=0.2mm+0.2mm+0.5mm, resulting in the thickening of the entire machine, which cannot meet the user's demand for lightweight and thin electronic devices (especially folding machines).

[0130] As shown in (b) of FIG4 , in another solution, the conductive foam can be set between the shielding cover (used to shield electromagnetic interference and / or strengthen the mainboard strength, etc., generally made of metal) and the display screen, and the two ends of the conductive foam are respectively in contact with the shielding cover and the display screen, thereby realizing the electrical connection of the display screen. Compared with the solution shown in (a) of FIG4 , this solution does not require high thickness of the whole machine. Specifically, the shielding cover can be set on the mainboard through surface mount technology (SMT), wherein the metal wall thickness of the shielding cover needs to be more than 0.2mm, and the working height of the conductive foam needs to be more than 0.5mm. When the conductive foam is used to electrically connect the shielding cover and the display screen, the height dimension from the mainboard to the display screen requires at least 0.7mm of the whole machine cavity space, and the height of the SMT components (including the shielding cover) soldered on the mainboard is greater than this value, so the thickness of the whole machine will not be increased due to the addition of the conductive foam. However, since the conductive foam is in contact with the shielding cover, the surface of the shielding cover that contacts the conductive foam is larger than the area of ​​the conductive foam. For example, the contact surface area of ​​a single piece of conductive foam is 2.5mm*6.5mm=16.25mm 2 When the shielding cover is installed, it needs to occupy 16.25mm on the motherboard. 2 In order to avoid increasing the height of the whole machine, the shielding cover is not enough to arrange the components. That is, the mainboard area occupied by the shielding cover cannot be used to arrange the components, resulting in a loss of mainboard layout area. The more conductive foam is needed, the greater the loss of layout area. For example, when more than 6 pieces of conductive foam are used, the layout area loss on the mainboard is 100mm. 2The above seriously affects the device layout space. In addition, due to the relatively regular shape design of the foam, this solution also increases the difficulty of layout.

[0131] Because the conductive foam is compressed during operation, it generates a force against the display screen, which affects the reliability of the display screen. Generally, the force against the screen generated by a single piece of conductive foam is about 1N. The more conductive foams are needed, the greater the force against the screen. For example, when more than 6 pieces of conductive foam are used, a force against the screen of more than 6N will be generated. On the one hand, the conductive foam applies a force against the screen to a part of the display screen, which has a greater impact on the film printing. On the other hand, the current display screen and the housing of the electronic device are usually bonded by dispensing or backing glue. The force against the screen generated by the conductive foam leads to the risk of debonding of the screen.

[0132] In view of this, the present application provides an electrical connection solution for a display screen, which can reduce the thickness of the entire device while improving the reliability of the screen and the device layout space within the electronic device.

[0133] Figures 5 and 6 illustrate schematic structural diagrams of an electronic device provided in an embodiment of the present application. Figure 5 is an exploded schematic diagram of electronic device 200, and Figure 6 is a partial cross-sectional schematic diagram of electronic device 200. The electronic device 200 shown in Figures 5 and 6 may be an example of the electronic device 100 in Figure 1.

[0134] As shown in Figures 5 and 6, electronic device 200 includes a display screen 21, a conductive component 22, an elastic member 23, and a metal member 24. The conductive component 22 and the elastic member 23 are disposed between the display screen 21 and the metal member 24, wherein the display screen 21 is electrically connected to the conductive component 22, and the elastic member 23 is electrically connected to the metal member 24.

[0135] The conductive component 22 is disposed between the display screen 21 and the elastic member 23 . The conductive component 22 includes a connecting portion 221 and an abutting portion 222 . The connecting portion 221 is connected to the display screen 21 , and the abutting portion 222 abuts against the elastic member 23 .

[0136] The elastic member 23 is disposed between the conductive component 22 and the metal component 24. The elastic member 23 includes a first end 231, a second end 232, and a deformable section 233. The deformable section 233 is located between the first and second ends 231 and is elastically deformable. The first end 231 is connected to the metal component 24, and the second end 232 abuts against the abutment portion 222 under the elastic force generated by the deformable section 233, thereby electrically connecting the elastic member 23 and the conductive component 22.

[0137] Referring to Figure 6 , (a) shows the elastic member 23 in a free state, with an initial height of Z1. (b) shows the elastic member 23 in a compressed state, with an operating height of Z2. For example, the operating height of the elastic member 23 is approximately 0.25 mm, which is smaller than the operating height of the conductive foam, which is 0.5 mm to 0.8 mm.

[0138] In the embodiment of the present application, the display screen 21 is electrically connected to the conductive component 22, and the elastic member 23 is electrically connected to the metal member 24. Under the elastic force of the elastic member 23, the conductive component 22 and the elastic member 23 can be reliably electrically connected, thereby achieving a reliable electrical connection between the display screen 21 and the metal member 24. Compared with conductive foam, the elastic member 23 has a smaller working height and contact area, and occupies less space, which is beneficial to reducing the thickness of the entire machine and increasing the device layout space within the electronic device, thereby improving space utilization. In addition, the top screen force generated by the elastic member 23 is small, which can reduce or avoid the risk of screen degumming, and the conductive component 22 can disperse the elastic force of the elastic member 23 to the surface, which can reduce or avoid the problem of screen film printing, thereby improving the reliability of the screen. In addition, the display screen electrical connection solution provided in the embodiment of the present application is simple in structure and low in cost.

[0139] In the embodiment of the present application, the display screen 21 and the conductive component 22 may be directly or indirectly electrically connected. The elastic member 23 and the metal member 24 may be directly or indirectly electrically connected.

[0140] In some embodiments, the second end 232 and the abutting portion 222 are in point contact, and the abutting portion 222 and the display screen 21 are in surface contact.

[0141] In some embodiments, referring to Figures 5 and 6 , the display screen 21 includes a stacked display layer 211 and a first conductive layer 212. The first conductive layer 212 is disposed on the side of the display layer 211 facing away from the light-emitting surface. The display layer 211 is used to display interface content, such as images and / or text data. The first conductive layer 212 is used to achieve electrical connection to the display screen 21. Specifically, the first conductive layer 212 is electrically connected to the conductive component 22. In some embodiments, the first conductive layer 212 also serves as a support layer for the display layer 211.

[0142] In the embodiment of the present application, the first conductive layer 212 may be a single-layer structure or a multi-layer structure (ie, a composite layer).

[0143] As an example, when the first conductive layer 212 has a single-layer structure, the material of the first conductive layer 212 can be a metallic conductive material, such as stainless steel, titanium alloy, aluminum alloy, vinyl carbonate (VC), copper, silver, etc.; or a non-metallic conductive material, such as carbon fiber, carbon nanotubes, titanium carbide, graphene, zinc oxide, and some conductive polymer materials, conductive ceramic materials, etc. Exemplarily, the first conductive layer 212 is in a sheet shape.

[0144] As another example, referring to FIG7 , when the first conductive layer 212 has a multi-layer structure, the first conductive layer 212 may include a stacked first dielectric layer 2121 and a first metal layer 2122. The first dielectric layer 2121 is disposed between the display layer 211 and the first metal layer 2122. The first dielectric layer 2121 provides a buffer and protective function, while the first metal layer 2122 is used to electrically connect to the conductive component 22 and provide electrical conductivity. In some cases, the first metal layer 2122 may also provide heat dissipation, support, or light shielding.

[0145] For example, the material of the first dielectric layer 2121 may include at least one of thermoplastic polyurethanes (TPU), polypropylene, polyethylene terephthalate (PET), polyvinylidene fluoride, or foam.

[0146] Exemplarily, the material of the first metal layer 2122 may include at least one of stainless steel, copper, titanium alloy, aluminum alloy or silver.

[0147] In some embodiments, the first conductive layer 212 further includes a first adhesive layer 2123 . The first adhesive layer 2123 is disposed between the first dielectric layer 2121 and the first metal layer 2122 to bond the first dielectric layer 2121 and the first metal layer 2122 .

[0148] In some embodiments, the first conductive layer 212 further includes a second adhesive layer 2124 . The second adhesive layer 2124 is disposed between the display layer 211 and the first dielectric layer 2121 for bonding the first dielectric layer 2121 and the display layer 211 .

[0149] Exemplarily, the material of the first adhesive layer 2123 and / or the second adhesive layer 2124 may be optical clear adhesive (OCA), double-sided grid adhesive or other conductive adhesive layers.

[0150] In some embodiments, the first conductive layer 212 may be a buffer heat dissipation film, also known as super clean foam (SCF). In other embodiments, the first conductive layer 212 may be a support plate (eg, a foldable support plate) for providing support for the display screen.

[0151] In the embodiment of the present application, the display layer 211 is a multi-layer structure (ie, a composite layer).

[0152] 8 , the display layer 211 may include a stacked polarizer (POL) 2112 , a display function layer 2113 , and a protective layer 2114 . The display function layer 2113 is disposed between the polarizer 2112 and the protective layer 2114 .

[0153] In some embodiments, the display screen 21 further includes a cover glass (CG) 2111. The cover glass 2111 is disposed on a polarizer 2112. Specifically, the polarizer 2112 is disposed between the cover glass 2111 and the display function layer 2113, and the display function layer 2113 is disposed between the polarizer 2112 and the protective layer 2114.

[0154] The cover glass 2111 primarily serves a protective function and, in some cases, can also enhance the appearance and provide decorative effects. For example, the cover glass 2111 can be 2D glass, 2.5D glass, or 3D glass. 2D glass is straight glass, while 2.5D and 3D glass are curved glass. In some cases, the cover glass 2111 can also be referred to as a glass cover plate.

[0155] The polarizer 2112 is used to convert unpolarized light into polarized light, or to change the polarization direction of polarized light.

[0156] The display function layer 2113 is a layer that mainly realizes the display function and can convert electrical signals into visual information. In some embodiments, the display function layer 2113 is a screen display control panel (PNL).

[0157] The protective layer 2114 primarily serves a protective function. It is connected to the first conductive layer 212. In some embodiments, the protective layer 2114 may be a back film (BF). For example, the protective layer 2114 may be made of polyethylene terephthalate (PET) or polyimide (PI).

[0158] In some embodiments, the display layer 211 further includes a third adhesive layer 2115, which is disposed between the cover glass 2111 and the polarizer 2112 to bond the cover glass 2111 and the polarizer 2112. For example, the third adhesive layer 2115 may be made of optical adhesive or double-sided grid adhesive.

[0159] In some embodiments, the display layer 211 further includes a fourth adhesive layer 2116, which is disposed between the display function layer 2113 and the protective layer 2114 and is used to bond the display function layer 2113 and the protective layer 2114. Exemplarily, the fourth adhesive layer 2116 may be made of optical adhesive, double-sided grid adhesive, pressure sensitive adhesive (PSA), or the like.

[0160] It can be understood that the stacked structure of the display layer 211 shown in FIG8 is merely exemplary. For different types of electronic devices, the stacked structures of the display layers are also different, which will not be described one by one here.

[0161] In some embodiments, the conductive component 22 may be a single-layer structure. For example, the connecting portion 221 and the abutting portion 222 each include a single-layer material. For example, the connecting portion 221 includes a supporting layer, and the abutting portion 222 includes a conductive layer.

[0162] In other embodiments, the conductive component 22 is a stacked structure, which will be described below with reference to FIG. 9 and FIG. 10 .

[0163] As an example, referring to FIG9 , both the connecting portion 221 and the abutting portion 222 include a second conductive layer 224, and the connecting portion 221 further includes a first cover layer (CVL) 223 and a second cover film 225 stacked with the second conductive layer 224. The first cover film 223 and the second cover film 225 are respectively arranged on both sides of the second conductive layer 224 in the thickness direction of the display screen. For example, the first cover film 223 is arranged on the side of the second conductive layer 224 close to the display screen 21, and the second cover film 225 is arranged on the side of the second conductive layer 224 close to the elastic member 23. The first cover film 223 and the second cover film 225 can play a protective role or provide coverage for subsequent surface treatment. The second conductive layer 224 is used for electrical conduction. In particular, the second conductive layer 224 of the abutting portion 222 is used for electrical connection with the elastic member 23.

[0164] This has lower processing requirements for the conductive component 22, and since the number of stacked layers of the abutment portion 222 is less than the number of stacked layers of the connection portion 221, local thinning of the conductive component 22 is achieved. The saved space can provide space for the working height of the elastic member 23, which is beneficial to reducing the thickness of the entire machine and has greater benefits for the inner cavity of the electronic device.

[0165] In some embodiments, the first cover film 223 and the second cover film 225 are made of polyimide.

[0166] Similar to the first conductive layer 212 , the second conductive layer 224 may be a single-layer structure or a multi-layer structure.

[0167] For example, when the second conductive layer 224 is a single-layer structure, the material of the second conductive layer 224 can be a metal conductive material, such as stainless steel, titanium alloy, aluminum alloy, vinyl carbonate (VC), copper, silver, etc.; or a non-metallic conductive material, such as carbon fiber, carbon nanotubes, titanium carbide, graphene, zinc oxide, and some conductive polymer materials, conductive ceramic materials, etc.

[0168] For another example, when the second conductive layer 224 has a multi-layer structure, the second conductive layer 224 may include at least one metal layer. Referring to FIG9 , the second conductive layer 224 may include a stacked second metal layer 2242, a second dielectric layer 2241, and a third metal layer 2243. The second metal layer 2242 and the third metal layer 2243 are respectively disposed on opposite sides of the second dielectric layer 2241 in the thickness direction of the display screen. For example, the second metal layer 2242 is disposed on the side of the second dielectric layer 2241 closest to the display screen 21, and the third metal layer 2243 is disposed on the side of the second dielectric layer 2241 closest to the elastic member 23. With respect to the connecting portion 221, the second metal layer 2242 is located between the second dielectric layer 2241 and the first cover film 223, and the third metal layer 2243 is located between the second dielectric layer 2241 and the second cover film 225. Here, the second dielectric layer 2241 primarily serves as a support for the second metal layer 2242 and the third metal layer 2243.

[0169] The laminated structure design of the second conductive layer 224 can improve the strength and stability of the conductive component 22 while ensuring the conductive performance of the conductive component 22 .

[0170] In the above embodiment, the second metal layer 2242 and the third metal layer 2243 can be a single-layer structure or a multi-layer structure, which is not limited in this application. Alternatively, the second conductive layer 224 can include the second metal layer 2242 or the third metal layer 2243.

[0171] In some embodiments, as shown in FIG10 , the second conductive layer 224 may further include a first plating layer 2244 and a second plating layer 2245. The first plating layer 2244 is disposed on the side of the second metal layer 2242 closer to the display screen 21, and the second plating layer 2245 is disposed on the side of the third metal layer 2243 closer to the elastic member 23. With respect to the connecting portion 221, the first plating layer 2244 is disposed between the second metal layer 2242 and the first cover film 223, and the second plating layer 2245 is disposed between the third metal layer 2243 and the second cover film 225. The first plating layer 2244 and the second plating layer 2245 are used to improve the performance of the conductive component 22, such as enhancing at least one of corrosion resistance, wear resistance, conductivity, or hardness.

[0172] For example, the first plating layer 2244 and / or the second plating layer 2245 may include at least one of a gold plating layer, a nickel plating layer, and a silver plating layer. The silver plating layer can improve the conductivity of the conductive component 22. The nickel plating layer can improve the corrosion resistance and wear resistance of the conductive component 22. The gold plating layer can improve the conductive contact impedance and enhance the conductive performance.

[0173] As another example, referring to FIG11 , the connection portion 221 includes a stacked first cover film 223, a support layer 227, and a second cover film 225. The first cover film 223 and the second cover film 225 are respectively disposed on both sides of the support layer 227 in the thickness direction of the display screen. For example, the first cover film 223 is disposed on the side of the support layer 227 close to the display screen 21, and the second cover film 225 is disposed on the side of the support layer 227 close to the elastic member 23. The contact portion 222 includes a second conductive layer 224.

[0174] That is, the difference between the laminated structure shown in FIG11 and the laminated structure shown in FIG9 is that the second conductive layer 224 in the connecting portion 221 is replaced by a support layer 227 without including a metal layer, which can further reduce the thickness of the conductive component 22.

[0175] Of course, in some embodiments, the connection portion 221 may include one of the first cover film 223 and the second cover film 225 , or may not include a cover film but only include the support layer 227 .

[0176] Illustratively, the second conductive layer 224 may include a stacked second metal layer 2242, a second dielectric layer 2241, and a third metal layer 2243. The second metal layer 2242 and the third metal layer 2243 are respectively disposed on both sides of the second dielectric layer 2241 in the thickness direction of the display screen. For example, the second metal layer 2242 is disposed on a side of the second dielectric layer 2241 close to the display screen 21, and the third metal layer 2243 is disposed on a side of the second dielectric layer 2241 close to the elastic member 23.

[0177] In some embodiments, in the stacked structure shown in Figure 11, the second conductive layer 224 may also include a first plating layer 2244 and a second plating layer 2245 as shown in Figure 10, the first plating layer 2244 is arranged on the side of the second metal layer 2242 close to the display screen 21, and the second plating layer 2245 is arranged on the side of the third metal layer 2243 close to the elastic member 23.

[0178] In some embodiments, the material of the second dielectric layer 2241 or the support layer 227 mentioned above may include at least one of polyimide (PI), TPU, polypropylene, PET, or polyvinylidene fluoride. The material of the second dielectric layer 2241 and the support layer 227 may be the same or different, and this application does not limit this.

[0179] In some embodiments, the second dielectric layer 2241 and the support layer 227 are located on the same layer, or in other words, the second dielectric layer 2241 and the support layer 227 are formed at one time. For example, the material of the second dielectric layer 2241 is the same as that of the support layer 227.

[0180] In some embodiments, as shown in Figures 9 to 11 , the connection portion 221 may further include a fifth adhesive layer 226 . The fifth adhesive layer 226 is disposed on a side of the first cover film 223 that is adjacent to the display screen 21 and is used to bond the connection portion 221 to the display screen 21 (e.g., specifically, the first conductive layer 212 ). In some embodiments, the fifth adhesive layer 226 may also be referred to as adhesive backing. Exemplary materials for the fifth adhesive layer 226 include optical adhesive, double-sided mesh adhesive, or insulating foam adhesive.

[0181] FIG12 shows a schematic structural diagram of a conductive component provided in an embodiment of the present application.

[0182] As shown in (a) of Figure 12, there is a gap H between the surface of the abutment portion 222 facing the display screen 21 and the surface of the display screen 21 facing the abutment portion 222. When the second end 232 of the elastic member 23 applies a force to the abutment portion 222, the abutment portion 222 can move relative to the connecting portion 221 in a direction close to the display screen 21, and eventually contact the display screen 21. Under the elastic force of the elastic member 23, the abutment portion 222 abuts against the display screen 21, thereby achieving a reliable electrical connection between the abutment portion 222 and the display screen 21. It can be understood that the gap H involved here refers to the gap formed after the conductive component 22 and the display screen 21 are assembled. In the fully assembled state, after the elastic member 23 applies a force to the abutment portion 222, the abutment portion 222 will move or deform in the gap H along the thickness direction of the display screen, and the gap H may be eliminated.

[0183] That is to say, when the conductive component 22 is in the initial state (i.e., the state when it is not assembled with other components), that is, when the abutting portion 222 is not abutting against the second end 232, there is a preset distance between the surface of the abutting portion 222 facing the display screen 21 and the surface of the connecting portion 221 facing the display screen 21. The preset distance is used when the conductive component 22 is in the assembled state, and the abutting portion 222 moves along the thickness direction of the display screen in the gap H formed under the elastic force of the elastic member 23 until it abuts against the display screen 21.

[0184] Since there is a gap H between the abutting portion 222 and the display screen 21, the abutting force between the abutting portion 222 and the display screen 21 is only provided by the elastic member 23, which has good controllability and facilitates the design of the dimensional parameters and elastic force of the elastic member 23. In addition, the existence of the gap H can offset the errors generated during the processing and assembly process, avoiding the occurrence or aggravation of the film printing problem. Assuming that there is no gap H between the abutting portion 222 and the display screen 21, if there are errors in the processing and assembly of the conductive component 22, the surface of the abutting portion 222 facing the display screen 21 may be closer to the display screen 21 than the surface of the connecting portion facing the display screen 21. In this way, after the conductive component 22 is attached to the display screen 21, the abutting portion 222 will exert a certain pressure on a part of the display screen 21, and this pressure will affect the film printing.

[0185] In some embodiments, as shown in FIG12( b ), the conductive component 22 may include a connecting portion 221, an abutting portion 222, and an elastic arm 228. The elastic arm 228 connects the abutting portion 222 and the connecting portion 221. The elastic arm 228 is easily deformable, allowing the abutting portion 222 to move relative to the connecting portion 221 toward the display screen 21. This helps distribute the elastic force applied by the elastic member 23 over a larger surface, thereby improving or avoiding film printing.

[0186] In some embodiments, the material of the elastic arm 228 may include at least one of PI, TPU, polypropylene, PET, or polyvinylidene fluoride.

[0187] In some embodiments, the elastic arm 228 is located on the same layer as the second dielectric layer 2241 (or support layer 227) in the connecting portion 221 and the second dielectric layer 2241 in the abutting portion 222. Thus, the gap H and the elastic arm 228 can be achieved by utilizing the differences in the laminated structures of the various portions of the conductive component 22, resulting in a simple structure and cost savings.

[0188] In some embodiments, the conductive component 22 may include two connecting portions 221 and an abutting portion 222 disposed between the two connecting portions 221. For purposes of distinction, one of the two connecting portions 221 is referred to as the first connecting portion, and the other as the second connecting portion. Thus, opposite ends of the abutting portion 222 are connected to the first connecting portion and the second connecting portion, respectively. This ensures a reliable connection between the conductive component 22 and the display screen 21.

[0189] In some embodiments, the conductive component 22 may include two elastic arms 228. For purposes of distinction, one of the two elastic arms 228 is referred to as a first elastic arm, and the other as a second elastic arm. The first elastic arm is disposed between the first connecting portion and the abutting portion 222, and is used to connect the first connecting portion and the abutting portion 222. The second elastic arm is disposed between the second connecting portion and the abutting portion 222, and is used to connect the second connecting portion and the abutting portion 222. This ensures the reliability of the abutting portion 222 during its overall movement.

[0190] FIG13 shows a schematic structural diagram of an elastic member provided in an embodiment of the present application.

[0191] As shown in Figure 13, the elastic member 23 includes a first end 231, a second end 232 and a deformation section 233. The deformation section 233 is located between the first end 231 and the second end 232 and can undergo elastic deformation. Specifically, the deformation section 233 is in the shape of a curved sheet. When an external force is applied to the deformation section 233, it can store and release energy by bending. Exemplarily, the shape of the deformation section 233 can be an arc. In the embodiment of the present application, the first end 231 is a fixed end, the second end 232 is a free end, and the deformation section 233 can undergo elastic deformation. Therefore, the elastic member 23 is a single cantilever design, which can ensure the stability of the electrical connection.

[0192] In some embodiments, the surface of the second end 232 facing the display screen 21 includes a circular arc surface 2321 that protrudes toward the display screen 21. When the second end 232 abuts the abutting portion 222, it is the circular arc surface 2321 that actually contacts the abutting portion 222. The design of the circular arc surface can ensure the reliability of the electrical connection between the second end 232 and the abutting portion 222.

[0193] In some embodiments, the second end 232 includes at least a portion of a sphere. Exemplarily, the second end 232 is spherical or hemispherical.

[0194] In some embodiments, the first end 231 includes a positioning portion 2311, which is used to position the elastic member 23 during assembly. For example, the positioning portion 2311 may be a through hole (e.g., a circular hole) or a protrusion (e.g., a cylinder). When the positioning portion 2311 is a protrusion, the protrusion is located on the side of the first end 231 facing the metal member 24. Accordingly, the location on the metal member 24 corresponding to the first end 231 includes a positioning feature, such as a corresponding hole feature (e.g., a through hole or a blind hole) or a protrusion feature. When the metal member 24 is provided with a protrusion, the protrusion is located on the side of the metal member 24 facing the first end 231. By way of example and not limitation, in actual applications, positioning can be achieved by aligning the positioning hole on the first end 231 with the positioning hole on the metal member 24; or by aligning the protrusion on the first end 231 with the positioning hole on the metal member 24; or by aligning the positioning hole on the metal member 24 with the positioning hole on the metal member 24. The present application is not limited to these positioning methods for the elastic member 23.

[0195] In some embodiments, the first end 231 includes a welding portion 2312 (such as the area indicated by the dashed line in FIG. 13 ), which is used to weld to the metal member 24. For example, the welding area of ​​the welding portion 2312 is approximately 2 mm by 2 mm. Compared to the 2 mm by 8 mm welding area required for conductive foam, the elastic member 23 provided in the embodiments of the present application can occupy a smaller area for welding to the metal member 24, saving space and facilitating device layout space.

[0196] Figure 14 shows a schematic diagram of an elastic force curve for an elastic member 23 provided in an embodiment of the present application. As shown in Figure 14 , the ordinate represents the reaction force generated by the force applied to the second end 232 of the elastic member 23, expressed in Newtons (N). The abscissa represents the displacement of the second end 232 of the elastic member 23 relative to its initial position along the thickness direction of the display screen when the force is applied to the second end 232 of the elastic member 23, expressed in millimeters (mm).

[0197] As can be seen from the figure, when the displacement of the elastic member 23 is in the range of 0-0.6mm, the reaction force generated is about 0-0.5N. In practical applications, the working height of the elastic member 23 can be controlled at about 0.25mm (such as between 0.2mm-0.55mm). Compared with the working height of 0.5mm-0.8mm required for the conductive foam, the elastic member 23 provided in the embodiment of the present application occupies a greatly reduced size in the thickness direction of the display screen, which is beneficial to reducing the thickness of the entire machine. Correspondingly, the top screen force of the elastic member 23 can be controlled between 0.2N-0.5N. Compared with the top screen force of more than 1N generated by the conductive foam, the top screen force generated by the elastic member 23 provided in the embodiment of the present application is greatly reduced, which is beneficial to improving the film printing problem and reducing the risk of screen degumming. Furthermore, the electrical connection of the display screen generally requires 5-8 grounding points. If conductive foam is used to electrically connect the display screen, in order to prevent the screen from falling off, it is necessary to pull the screen by widening the bonding area and the glue area, which will increase the black edge of the screen. However, when the elastic part 23 provided in the present application is used to electrically connect the display screen, the top screen force generated by the elastic part 23 is small, which can greatly reduce the risk of screen debonding and improve the reliability of the screen, and can also improve the black edge of the screen and improve the competitiveness of the entire machine.

[0198] In addition, since the top screen force generated by the elastic member 23 is relatively small, it is beneficial to design a thinner display screen while ensuring screen reliability, such as reducing the thickness and / or number of the display screen layers, etc., to achieve a lightweight design of the electronic device.

[0199] 6 , in some embodiments, the electronic device 200 further includes a circuit board 25 , and the metal member 24 may be disposed on the circuit board 25 .

[0200] In the embodiment of the present application, there are various types of metal parts 24 .

[0201] As an example, referring to (a) in FIG. 15 , the electronic device 200 may include a circuit board 25 , and the metal member 24 may be a circuit board bracket, or a mainboard bracket.

[0202] As another example, referring to FIG15( b ), the metal member 24 may be a shielding cover. The shielding cover can be used to protect the internal components of the electronic device from external radiation and interference from external radiation. In some embodiments, the shielding cover can be disposed on and electrically connected to the circuit board 25. Because the elastic member 23 requires a low operating height, connecting the elastic member 23 to the shielding cover can improve the utilization of the mainboard layout.

[0203] As another example, metal member 24 may be a board-to-board (BTB) connector bracket. BTB connectors are primarily used for connecting printed circuit boards (PCBs), directly connecting the power and signals of the boards, effectively simplifying the use of parallel stacked PCBs. The BTB connector bracket is used to press-fit the BTB connectors and is also referred to as a press-fit BTB bracket.

[0204] As another example, the metal member 24 may be a middle frame, such as the middle frame 123 shown in FIG. 1 .

[0205] In some embodiments, as shown in (a) and (b) of FIG. 15 , the surface of the metal member 24 facing the elastic member 23 may be provided with a recessed portion 241 that is recessed away from the elastic member 23. The bottom wall of the recessed portion 241 is configured to connect to the first end 231 of the elastic member 23. Because the metal member 24 occupies a relatively small space, providing the recessed portion 241 on the metal member 24 for connection to the elastic member 23 can reduce the overall height of the device without affecting other components.

[0206] In some embodiments, as shown in FIG. 15( a ), the projection of the first end 231 of the metal member 24 in the thickness direction of the display screen is located within the projection range of the recessed portion 241 in the thickness direction of the display screen.

[0207] In some embodiments, as shown in FIG. 15( b ), the projection of the metal member 24 in the thickness direction of the display screen is located within the projection range of the recessed portion 241 in the thickness direction of the display screen.

[0208] In the embodiments of the present application, there are multiple ways to assemble the display screen electrical connection solution.

[0209] As an example, the elastic member 23 can be first connected (e.g., welded) to a metal member 24 (e.g., a shielding cover, a metal bracket), and then the assembly formed by connecting the elastic member 23 and the metal member 24 (which can be referred to as an elastic member) can be connected (e.g., welded) to a circuit board 25 (e.g., a motherboard). The conductive member 22 can be connected (e.g., by bonding with insulating adhesive or insulating foam adhesive) to the display screen 21. Specifically, the connecting portion 221 of the conductive member 22 can be connected to the layer of the display screen 21 closest to the circuit board (e.g., an SCF layer, a VC layer, or a stainless steel layer). Finally, the display screen 21 and the circuit board 25 are assembled together, and the second end 232 of the elastic member 23 abuts the abutting portion 222 of the conductive member 22 (e.g., the center area of ​​the abutting portion 222), for example, the second end 232 abuts the second conductive layer 224 of the abutting portion 222. Since the abutting portion 222 is in contact with the display screen 21 or has a small gap therebetween, under the elastic force of the elastic member 23, the second end 232 applies a force to the abutting portion 222, causing the abutting portion 222 to deform and abut against the display screen 21, thereby forming a complete electrical connection solution.

[0210] For example, this assembly method can be applied to flip-chip electronic devices. Flip-chip refers to the method of assembling an electronic device by first assembling the inner cavity and then the display screen.

[0211] As another example, the elastic member 23 can first be connected (e.g., welded) to the metal member 24 (e.g., a middle frame). The conductive component 22 can be connected (e.g., by bonding via insulating adhesive or insulating foam adhesive) to the display screen 21. Specifically, the connecting portion 221 of the conductive component 22 can be connected to the layer of the display screen 21 closest to the circuit board (e.g., an SCF layer, a VC layer, or a stainless steel layer). The display screen 21 connected to the conductive component 22 and the metal member 24 connected to the elastic member 23 can then be assembled together, such that the second end 232 of the elastic member 23 abuts the abutting portion 222 of the conductive component 22, for example, the second end 232 abuts the second conductive layer 224 of the abutting portion 222. Finally, the circuit board 25 can be assembled with the aforementioned assembled components.

[0212] For example, this assembly method can be applied to full-size electronic devices. Full-size refers to the method of assembling the screen and middle frame first and then the motherboard.

[0213] In some embodiments, for a foldable electronic device with an external screen, the inner screen is mounted upright and the outer screen is mounted in an inverted manner.

[0214] In some embodiments, the display screen 21 may be a flexible screen (ie, the screen can be bent and folded), or a rigid screen (ie, the screen cannot be bent and folded).

[0215] In an embodiment of the present application, the display screen 21 may include a display area and a non-display area, and the non-display area surrounds the display area. The display area is the area where the interface content can be displayed, and the non-display area is the area where the interface content is not displayed, which is usually black. For example, a cover plate (or screen frame or B shell) can be provided on the display screen 21, and the window area of ​​the cover plate is usually the display area, and the periphery of the window area is generally provided with an ink layer for shielding the non-display area of ​​the display screen 21. For another example, the display screen 21 can be fixed on a back plate (or A shell), and the area on the display screen 21 that overlaps with the back plate is usually the non-display area of ​​the display screen 21, and the area on the display screen 21 that does not overlap with the back plate is usually the display area of ​​the display screen 21.

[0216] In some embodiments, the projection of the elastic member 23 in the thickness direction of the display screen 21 overlaps with the projection of the display area of ​​the display screen 21 in the thickness direction of the display screen 21. Exemplarily, the projection of the elastic member 23 in the thickness direction of the display screen 21 is within the projection range of the display area of ​​the display screen 21 in the thickness direction of the display screen 21.

[0217] In some embodiments, the projection of the conductive component 22 in the thickness direction of the display screen 21 overlaps with the projection of the display area of ​​the display screen 21 in the thickness direction of the display screen 21. Exemplarily, the projection of the conductive component 22 in the thickness direction of the display screen 21 is within the projection range of the display area of ​​the display screen 21 in the thickness direction of the display screen 21.

[0218] The elastic member 23 and the conductive component 22 can be disposed in the display area of ​​the display screen, which is beneficial for the flexible layout of the electrical connection points and can also reduce the black edges formed in the non-display area.

[0219] In some embodiments, the display screen electrical connection solution provided by the embodiments of the present application can be applied to foldable electronic devices, such as foldable mobile phones.

[0220] Exemplarily, the electronic device 200 may be a foldable electronic device. As shown in Figure 16, the electronic device 200 may include two display screens 21, namely a folding screen 21a and a non-folding screen 21b, wherein the folding screen 21a may also be referred to as an inner screen, and the non-folding screen 21b may also be referred to as an outer screen. For the sake of distinction, in some cases, the non-folding screen 21b is referred to as a first display screen, and the folding screen 21a is referred to as a second display screen. The inner screen 21a can be folded or unfolded along a folding axis. The display area of ​​the outer screen 21b is less than half of the display area of ​​the inner screen 21a. The display screen electrical connection scheme provided in the embodiment of the present application can be applied to the inner screen 21a or to the outer screen 21b. When applied to the outer screen 21b, the conductive component 22, the elastic member 23 and the metal member 24 are arranged between the inner screen 21a and the outer screen 21b.

[0221] In some embodiments, the electronic device 200 (specifically the circuit board 25 mentioned above) may include a first circuit board 251 and a second circuit board 252, which are housed in a receiving space formed by the housing of the electronic device 200. The first circuit board 251 and the second circuit board 252 can rotate relative to each other around the folding axis of the electronic device 200. The first circuit board 251 is arranged between the inner screen 21a and the outer screen 21b, that is, the projection of the first circuit board 251 in the screen thickness direction (or the thickness direction of the electronic device) overlaps with the projection of the inner screen 21a in the screen thickness direction and the projection of the outer screen 21b in the screen thickness direction. The projection of the second circuit board 252 in the screen thickness direction overlaps with the projection of the inner screen 21a in the screen thickness direction, and does not overlap with the projection of the outer screen 21b in the screen thickness direction. It can be understood that the projections involved here are all projections when the flexible screen is in the unfolded state.

[0222] It should be noted that in the descriptions of the thickness direction such as "the thickness direction of the display screen", "the thickness direction of the screen", "the thickness direction of the electronic device" involved in the embodiments of the present application, when the display screen is a flexible screen, it refers to the thickness direction when the display screen is in the unfolded state.

[0223] In some embodiments, the electronic device 200 may further include a system on chip (SOC) 261 and a radio frequency integrated circuit (RFIC) (also called a radio frequency chip) 262, wherein the radio frequency chip 262 is arranged on the first circuit board 251 and the system on chip 261 is arranged on the second circuit board 252.

[0224] In some embodiments, the electronic device 200 may further include a first antenna and a second antenna, the first antenna being arranged in the housing where the RF chip 262 is located, and the second antenna being arranged in the housing where the system-level chip 261 is located. That is to say, the first antenna, the RF chip 262 and the first circuit board 251 can be located in the accommodation space formed by the first housing 121 as shown in Figure 2, and the second antenna, the system-level chip 261 and the second circuit board 252 can be located in the accommodation space formed by the second housing 122 as shown in Figure 2. Such a layout design can improve space utilization, improve the free and flexible layout of the antenna and the heat dissipation capacity. In addition, if the outer screen 21b is electrically connected using the solution provided in this application, the clutter problem of the first antenna can be solved. In addition, this layout can improve the battery-to-machine volume ratio, maximize the battery capacity in an extreme space, improve the overall battery life of the electronic device, and bring a better experience for mobile office.

[0225] The present application does not specifically limit the types of the first antenna and the second antenna. As an example and not a limitation, the first antenna is a cellular antenna and the second antenna is a short-range antenna.
