TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic devices, and more particularly, to an electronic device. BACKGROUND

[0002] With the continuous development of electronic devices, electronic devices with display screens (such as mobile phones, tablets, etc.) have become an indispensable part of people's daily life and work. For performance optimization considerations, the display screen on the electronic device is usually designed to be grounded, that is, the display screen is electrically connected with the metal parts (such as shielding cans, etc.) in the electronic device to form a grounding path, thereby realizing the grounding of the display screen.

[0003] Currently, conductive foam is usually used to realize the electrical connection of the display screen, but the conductive foam requires a large working height and contact area, which seriously affects the overall thickness and device layout space. Moreover, the conductive foam is compressed when working, which generates a large screen pressing force, and the risk of screen film printing and screen delamination is large, which affects the reliability of the screen.

[0004] Therefore, there is an urgent need to provide a display screen electrical connection scheme that can reduce the overall thickness while improving the reliability of the screen and the device layout space in the electronic device. SUMMARY

The specific form of the electronic device 100 is not specially limited in the embodiment of the present application, and the following description is given by taking the electronic device 100 as a folding mobile phone for the convenience of description and understanding.

[0096] For the convenience of description, the direction parallel to the folding axis of the electronic device 100 is defined 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 an unfolded state is defined as the Y direction, and the direction perpendicular to the screen when the electronic device 100 is in the unfolded state is defined as the Z direction.

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 components in the embodiment of the present application, and should not be understood as a limitation on the embodiment of the present application.

[0097] Referring to Figure 1 and Figure 2 , the electronic device 100 can include a flexible screen 110 and a housing 120. The housing 120 is formed with an accommodation space for accommodating various components of the electronic device 100, and the flexible screen 110 is arranged in the accommodation space formed by the housing 120 and connected to the housing 120. The housing 120 can also serve to protect the electronic device 100 and support the entire device.

[0098] The flexible screen 110 is used to display images, Figure 1 and Figure 2The flexible screen 110 is schematically represented by a structure filled with a dot matrix pattern. The flexible screen 110 has strong flexibility and bendability, and can provide a new interaction mode based on the bendability for a user. 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 (AMOLED), a flexible light-emitting diode (FLED), a quantum dot light emitting diode (QLED), and the like, which is not limited in the embodiments of the present application.

[0099] In the embodiments of the present application, the flexible screen 110 has a light-out surface capable of displaying a picture, and a side surface of the flexible screen 110 opposite to the light-out surface can be referred to as a back surface of the flexible screen 110. The back surface of the flexible screen 110 is accommodated in the accommodating space formed by the shell 120 and is not visible to a user.

[0100] The shell 120 can include a first shell 121 and a second shell 122, and the first shell 121 and the second shell 122 can rotate relative to each other about a folding axis 1301 of the electronic device 100.

The middle frame 123 is generally formed of a metal material such as copper, magnesium alloy, stainless steel, etc. In the embodiments of the present application, the middle frame 123 can be used to support and fix the flexible screen 110. For example, as shown in FIG. 1, the flexible screen 110 (specifically, the back of the flexible screen 110) can be bonded to the middle frame 123 by an adhesive 150.

[0107] ​​In some embodiments, the middle frame 123, the side frame 124, and the back cover 125 can be three parts of the housing 120 of the electronic device 100. That is, the middle frame 123 and the side frame 124 can be connected, and the side frame 124 and the back cover 125 can be connected. The connection methods include, but are not limited to, snap-fit, adhesive, welding, riveting, clearance fit, and other detachable or non-detachable connection methods. In other embodiments, the side frame 124 and the middle frame 123 can be an integral structure (or a one-piece molded structure); or, the side frame 124 and the back cover 125 can be an integral structure.

[0108] In some embodiments, reference Figure 2 As shown, the middle frame 123 may include a direction perpendicular to the folding axis 1301 (e.g., Figure 2 The first middle frame portion 1231 and the second middle frame portion 1232 are arranged in the Y direction shown, wherein the first middle frame portion 1231 and the second middle frame portion 1232 are located on both sides of the folding axis 1301.

[0109] In some embodiments, the border 124 may include a direction perpendicular to the folding axis 1301 (e.g., Figure 2 The first border portion 1241 and the second border portion 1242 are arranged in the Y direction shown, wherein the first border portion 1241 and the second border portion 1242 are located on both sides of the folding axis 1301, respectively.

[0110] In some embodiments, the back cover 125 may include a direction perpendicular to the folding axis 1301 (e.g., Figure 2 The first back cover portion 1251 and the second back cover portion 1252 are arranged in the Y direction shown, wherein the first back cover portion 1251 and the second back cover portion 1252 are located on both sides of the folding axis 1301, respectively.

[0111] In this embodiment of the application, at least a portion 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 may form a first housing 121 and a second housing 122 for supporting the flexible screen 110.

[0112] For example, the first housing 121 may include a first middle frame portion 1231, a first side 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 side frame portion 1242, and a second back cover portion 1252. The first middle frame portion 1231, the first side 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 side frame portion 1242, and the second back cover portion 1252 are also located on the same side of the folding axis 1301.

[0113] In some embodiments, the flexible screen 110 can include a first display part 111 corresponding to the first shell 121, a second display part 112 corresponding to the second shell 122, and a third display part 113 corresponding to the hinge mechanism 130, the third display part 113 being located between the first display part 111 and the second display part 112, and the third display part 113 being a foldable display part. For example, the first display part 111 is fixed to the first shell 121, the second display part 112 is fixed to the second shell 122, and the third display part 113 is fixed to the hinge mechanism 130. Under the action of the hinge mechanism 130, the first shell 121 and the second shell 122 can be close to or away from each other, and correspondingly, the first display part 111 and the second display part 112 can be close to or away from each other, and the third display part 113 will be bent, so that the flexible screen 110 can be folded or unfolded.

[0114] Reference Figure 2 As shown, the electronic device 100 further includes a circuit board 140, which is accommodated in the accommodating space formed by the shell 120 and connected with the shell 120 (for example, the middle frame 123). The circuit board 140 has the function of supporting and interconnecting circuit elements. Specifically, the circuit board 140 is a support body of 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, flashlights, microphones, batteries, antennas, etc. In some embodiments, the circuit board integrated with electronic components (such as processors, radio frequency chips, board-to-board connectors, controllers or external interfaces, etc.) can be referred to as a mainboard.

[0115] In some embodiments, the circuit board 140 can include a first circuit board (or first mainboard) 141 and a second circuit board (or second mainboard) 142, and the first circuit board 141 and the second circuit board 142 are located on both sides of the folding axis 1301, for example, the first circuit board 141 is accommodated in the accommodating space formed by the first shell 121 and the first display part 111, and the second circuit board 142 is accommodated in the accommodating space formed by the second shell 122 and the second display part 112.

[0116] In the embodiments of the present application, the electronic device 100 can be switched between a folded state and an unfolded state. When the electronic device 100 is in the folded state, the occupied space of 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 viewable range of the user.

[0117] For example, Figure 1The electronic device 100 shown is in an unfolded state, and accordingly, the flexible screen 110 is in an unfolded state, the first display part 111 and the second display part 112 are located on the same plane, and the user can conveniently use a large screen.

[0118] Exemplarily, Figure 3 Two possible folding states of the electronic device 100 are shown. In the embodiments of the present application, the electronic device 100 in a folded state can mean that the electronic device 100 is currently bent, and the bending degree of the electronic device 100 reaches the maximum. At this time, the first display part 111 and the second display part 112 can be regarded as being located on different planes.

[0119] Figure 3 (a) in FIG. 1 shows a state in which the screen of the electronic device 100 is folded outward, i.e., an outward folding state. In the outward folding state, the first display part 111, the second display part 112 and the third display part 113 can form a housing area for accommodating the first housing 121, the second housing 122 and the hinge mechanism 130. That is, the first housing 121, the second housing 122 and the hinge mechanism 130 can be accommodated in the interval space between the first display part 111 and the second display part 112. At this time, the first display part 111 is opposite to the second display part 112, the first housing 121 is opposite to the second housing 122, and the third display part 113 is bent.

[0120] Figure 3 (b) in FIG. 1 shows a state in which the screen of the electronic device 100 is folded inward, i.e., an inward folding state. In the inward folding state, the first housing 121, the second housing 122 and the hinge mechanism 130 can form a screen housing area for accommodating the flexible screen 110. That is, the flexible screen 110 can be accommodated in the interval space between the first housing 121 and the second housing 122. At this time, the first display part 111 is opposite to the second display part 112, the first housing 121 is opposite to the second housing 122, and the third display part 113 is bent.

[0121] In some embodiments, when the flexible screen 110 is an inner folding screen, the electronic device 100 can further include an outer screen 160, which is generally disposed on one side of the back cover 125 and opposite to the non-bending area (e.g., the first display part 111 or the second display part 112) of the flexible screen 110. For example, the outer screen 160 can be disposed on the front surface of the electronic device 100 in the folded state. The outer screen 160 can be used to display a user interface, an application, an image, a video, a notification, or information that is convenient for the user to operate or view in daily life. In some embodiments, the outer screen 160 can have a touch function to facilitate the user to interact with the electronic device 100 through the outer screen 160. The outer screen 160 (specifically, the back surface of the outer screen 160) can be bonded to the middle frame 123 by the adhesive 150. Generally, the outer screen 160 includes a glass cover plate disposed on the outermost side of the light-emitting surface of the outer screen 160.

[0122] In some embodiments, the flexible screen 110 can also be referred to as a main screen or a folding screen, and the outer screen 160 can 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 outer screen 160 are collectively referred to as a display screen. In the following embodiments, if the electronic device 100 includes multiple display screens, different display screens are distinguished as a first display screen, a second display screen, and the like.

[0123] It should be understood that Figures 1 to 3 It is only schematically shown that the electronic device 100 includes two foldable parts (the first housing 121 and the second housing 122), i.e., the electronic device 100 has one folding axis. In other embodiments, the electronic device 100 can further include three or more foldable parts, and accordingly, the electronic device 100 has two or more folding axes, such as a two-fold phone, a three-fold phone, and a multi-fold phone, etc., so that the user can fold multiple times along multiple folding axes. With the increase in the number of foldable parts of the electronic device 100, the electronic device 100 can further reduce the occupied space in the folded state while keeping the same screen size in the unfolded state; or the electronic device 100 can further enlarge the displayed screen area in the unfolded state while occupying the same space in the folded state.

[0124] It should also be understood that Figures 1 to 3 It is only schematically shown that the electronic device 100 includes some components, and the shape, size, and structure of these components are not limited Figures 1 to 3 In other embodiments, the electronic device 100 can further include more or fewer components than those shown, and the embodiments of the present application are not limited thereto. In other embodiments, the type of the electronic device 100 is different, and the components included in the electronic device 100 are different, for example, the electronic device 100 can also be a side sliding phone, a straight phone, etc., and the foldable phone structure provided in the embodiments of the present application is only exemplary.

[0125] For performance optimization, the display screen on the electronic device is usually designed to be grounded, that is, the display screen is electrically connected with metal parts (such as middle frame, mainboard support, shielding cover, etc.) in the electronic device to form a ground return path, thereby realizing the grounding of the display screen. For example, users of electronic devices often have static electricity, which will hit the display screen after contacting the electronic device, causing electro-static discharge (ESD). In order to improve the anti-static ability of the display screen, the display screen is usually grounded. For another example, when the display screen is working normally, the electronic devices (such as light-emitting diodes, semiconductors, etc.) in the display screen will accumulate electric charges, or static electricity will be generated between the electronic device and the impact object after the electronic device falls. These electric charges will gradually accumulate on the display screen. If the electric charges accumulate too much on the display screen, it may affect the normal use of the display screen, such as causing the phenomenon of bright circle or light leakage due to the inability to effectively control the bright and dark of the local area of the display screen. Grounding the display screen can transfer the excess electric charges on the display screen, thereby avoiding the influence of the accumulation of too much electric charges on the display effect of the display screen. For another example, if an antenna is arranged between two display screens (such as the flexible screen 110 and the outer screen 160) arranged opposite to each other, the electric charges on the display screen will cause the spurious problem of the antenna, such as radiated spurious emission (RSE). Grounding at least one display screen can transfer the electric charges on the display screen, which is beneficial to improve the radio frequency performance of the electronic device.

[0126] Currently, conductive foam is usually used to realize the electrical connection of the display screen. The conductive foam is a kind of foam material with conductive performance, which is mixed with fillers with good conductive performance, such as carbon fibers and copper powder, so that the foam material has conductive characteristics. However, the conductive foam needs a large working height and contact area, for example, in order to solve the display screen film printing problem, the conventional design usually selects the conductive foam with an initial height of 1.5 mm and a working height of 0.5 mm-0.8 mm, for another example, in order to avoid the RSE problem, the conductive foam has a minimum design area requirement (such as a contact area of 2.5 mm*6.5 mm), and multiple conductive foams usually need to be arranged in the electronic device, which seriously affects the thickness of the whole machine and the device layout space. Moreover, the conductive foam is compressed when working, and the top screen force generated by each piece of conductive foam on the display screen is about 1 newton (symbol: N). The more the number of conductive foams, the greater the top screen force, and the greater the risk of film printing and screen delamination of the display screen, which affects the reliability of the screen.

[0127] For the convenience of understanding, an example is shown as follows. Figure 4 A schematic diagram of a scheme for realizing the electrical connection of the display screen by using the conductive foam is shown.

[0128] For example, Figure 4In the (a) shown in the above, in one scheme, the conductive foam can be arranged between the mainboard support (usually having one or more functions of press plate-to-plate connector, laser antenna for laser direct structuring technology (LDS), bearing parts, reinforcement, etc., generally being metal material or including metal material) and the display screen, and the two ends of the conductive foam abut against the mainboard support and the display screen respectively, so as to realize the electrical connection of the display screen. However, this scheme has a high requirement on the thickness of the whole machine. Specifically, the mainboard support is usually arranged between the mainboard and the display screen, wherein the gap between the mainboard support metal surface and the devices on the mainboard needs to be more than 0.2 mm, the mainboard support metal wall thickness needs to be more than 0.2 mm, and the working height of the conductive foam needs to be more than 0.5 mm. In the case that the types of the devices are consistent, when the conductive foam is used to electrically connect the mainboard support and the display screen, the height dimension from the mainboard to the display screen needs to be additionally increased by more than 0.9 mm of the internal cavity space of the whole machine, wherein 0.9 mm = 0.2 mm + 0.2 mm + 0.5 mm, which leads to the thickening of the whole machine and cannot meet the user's demand for the thinning of the electronic device (especially the folding machine).

[0129] As shown in the (b) shown in the above, Figure 4 In another scheme, the conductive foam can be arranged between the shielding cover (usually being metal material, used for shielding electromagnetic interference and / or reinforcing the strength of the mainboard, etc.) and the display screen, and the two ends of the conductive foam abut against the shielding cover and the display screen respectively, so as to realize the electrical connection of the display screen. Compared with the scheme shown in the (a) shown in the above, Figure 4 The scheme has a low requirement on the thickness of the whole machine. Specifically, the shielding cover can be arranged on the mainboard by surface mount technology (SMT), wherein the shielding cover metal wall thickness needs to be more than 0.2 mm, and the working height of the conductive foam needs to be more than 0.5 mm. 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 needs at least 0.7 mm of the internal cavity space of the whole machine, and the height of the SMT device (including the shielding cover) welded on the mainboard is greater than this value, so the thickness of the whole machine will not be increased due to the conductive foam. However, since the conductive foam is in contact with the shielding cover, the area of the surface of the shielding cover in contact with the conductive foam is greater than the area of the conductive foam, for example, when the contact surface area of a single conductive foam is 2.5 mm*6.5 mm=16.25 mm 2 , the shielding cover needs to occupy an area of 16.25 mm 2 on the mainboard. In order not to increase the height of the whole machine, the internal part of the shielding cover is insufficient to arrange devices, that is, the area of the mainboard occupied by the shielding cover cannot be used to arrange devices, thereby causing the loss of the device arrangement area on the mainboard. When the number of the conductive foams needed is more, the loss of the device arrangement area on the mainboard is more, for example, when more than 6 pieces of conductive foams are arranged, the loss of the device arrangement area on the mainboard is 100 mm2 The above seriously affects the device layout space. Moreover, since the shape of the foam is relatively regular, the scheme also increases the layout difficulty.

[0130] Since the conductive foam is compressed when working, it will generate a screen pressing force on the display screen, which affects the reliability of the display screen. Generally, the screen pressing force generated by a single conductive foam is about 1N, and the more the number of conductive foams needed, the greater the screen pressing force. For example, when more than 6 conductive foams are arranged, a screen pressing force of more than 6N will be generated. On the one hand, the conductive foam exerts a screen pressing force on the local display screen, which greatly affects the film printing. On the other hand, the current display screen and the shell of the electronic device are usually bonded by point gluing or back gluing, and the screen pressing force generated by the conductive foam causes the screen to have a risk of delamination.

[0131] In view of this, the present application provides a display screen electrical connection scheme, which can reduce the thickness of the whole machine while improving the reliability of the screen and the device layout space in the electronic device.

[0132] Figure 5 And Figure 6 A schematic structural diagram of an electronic device provided by an embodiment of the present application is shown. Figure 5 FIG. 1 is an exploded schematic diagram of an electronic device, Figure 6 FIG. 2 is a partial cross-sectional schematic diagram of the electronic device. Figure 5 And Figure 6 The electronic device 200 shown can be Figure 1 one example of the electronic device 100 in FIG. 1.

[0133] As shown in Figure 5 and Figure 6 The electronic device 200 includes a display screen 21, a conductive assembly 22, an elastic member 23, and a metal member 24. The conductive assembly 22 and the elastic member 23 are arranged between the display screen 21 and the metal member 24, wherein the display screen 21 is electrically connected to the conductive assembly 22, and the elastic member 23 is electrically connected to the metal member 24.

[0134] The conductive assembly 22 is arranged between the display screen 21 and the elastic member 23. The conductive assembly 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.

[0135] The elastic member 23 is arranged between the conductive assembly 22 and the metal member 24. The elastic member 23 includes a first end 231, a second end 232, and a deformation segment 233, the deformation segment 233 is located between the first end 231 and the second end 232 and can be elastically deformed. The first end 231 is connected to the metal member 24, and the second end 232 abuts against the abutting portion 222 under the action of the elastic force generated by the deformation segment 233, so as to electrically connect the elastic member 23 and the conductive assembly 22.

[0136] Reference Figure 6 as shown, Figure 6 The elastic member 23 shown in (a) of FIG. 6 is in a free state, and has an initial height Z1. The elastic member 23 shown in (b) of FIG. 6 is in a compressed state, and has a working height Z2. Exemplarily, the working height of the elastic member 23 is about 0.25 mm, which is less than the working height of the conductive foam, which is 0.5 mm-0.8 mm.

[0137] In the embodiments of the present application, the display screen 21 is electrically connected with the conductive assembly 22, and the elastic member 23 is electrically connected with the metal member 24. Under the elastic force of the elastic member 23, the conductive assembly 22 and the elastic member 23 can be reliably electrically connected, so as to reliably electrically connect the display screen 21 and the metal member 24. Compared with the conductive foam, the working height and the contact area of the elastic member 23 are smaller, and the occupied space is smaller, which is beneficial to reduce the thickness of the whole machine and improve the device layout space in the electronic equipment and the space utilization. In addition, the screen pressing force generated by the elastic member 23 is small, which can reduce or avoid the risk of screen delamination, and the elastic force of the elastic member 23 can be dispersed to the surface by the conductive assembly 22, which can reduce or avoid the screen film printing problem, so as to improve the reliability of the screen. Moreover, the display screen electrical connection scheme provided by the embodiments of the present application has simple structure and low cost.

[0138] In the embodiments of the present application, the display screen 21 and the conductive assembly 22 can be directly electrically connected or indirectly electrically connected. The elastic member 23 and the metal member 24 can be directly electrically connected or indirectly electrically connected.

The display layer 211 is used to display interface content, such as image and / or text data. The first conductive layer 212 is used to realize the electrical connection of the display screen 21, and specifically, the first conductive layer 212 is electrically connected with the conductive assembly 22. In some embodiments, the first conductive layer 212 also serves as a support layer of the display layer 211, and plays a supporting role.

[0141] In the embodiments of the present application, the first conductive layer 212 can be a single-layer structure or a multi-layer structure (i.e., a composite layer).

[0142] As an example, when the first conductive layer 212 is a single-layer structure, the material of the first conductive layer 212 can be a metal conductive material, such as stainless steel, titanium alloy, aluminum alloy, copper, silver, etc., or a non-metal conductive material, such as carbon fiber, carbon nanotube, titanium carbide, graphene, zinc oxide, and some conductive polymer materials, conductive ceramic materials, etc. For example, the first conductive layer 212 is in a sheet shape.

[0143] As another example, referring to Figure 7 , when the first conductive layer 212 is a multi-layer structure, the first conductive layer 212 can include a first dielectric layer 2121 and a first metal layer 2122 stacked together, the first dielectric layer 2121 is arranged between the display layer 211 and the first metal layer 2122, the first dielectric layer 2121 serves as a buffer and protection, and the first metal layer 2122 is used to electrically connect with the conductive component 22 and serves as a conductive layer. In some cases, the first metal layer 2122 can also serve as a heat dissipation, support, light shielding, etc.

[0147] In some embodiments, the first conductive layer 212 further includes a second adhesive layer 2124 arranged between the display layer 211 and the first dielectric layer 2121, for bonding the first dielectric layer 2121 and the display layer 211.

[0148] For example, the material of the first adhesive layer 2123 and / or the second adhesive layer 2124 can be optical clear adhesive (OCA), double-sided grid adhesive, or other conductive adhesive layer, etc.

[0149] In some embodiments, the first conductive layer 212 can be a buffer heat dissipation film, which can also be referred to as a super clean foam (SCF). In other embodiments, the first conductive layer 212 can be a support plate (e.g., a foldable support plate) for providing support force for the display screen.

[0150] In the embodiments of the present application, the display layer 211 is a multi-layer structure (i.e., a composite layer).

[0151] In one example, referring to FIG. 2A, the display layer 211 can include a polarizer (POL) 2112, a display function layer 2113, and a protective layer 2114 arranged in a stack. Figure 8

[0152] In some embodiments, the display screen 21 further includes a cover glass (CG) 2111. The cover glass 2111 is arranged above the polarizer 2112. Specifically, the polarizer 2112 is arranged between the cover glass 2111 and the display function layer 2113, and the display function layer 2113 is arranged between the polarizer 2112 and the protective layer 2114.

[0153] The cover glass 2111 mainly plays a protective role and can also play a role of beautifying appearance and decoration in some cases. For example, the cover glass 2111 can be a 2D glass, a 2.5D glass, or a 3D glass, in which the 2D glass is a straight glass, and the 2.5D glass and the 3D glass are curved glasses. In some cases, the cover glass 2111 can also be referred to as a glass cover plate.

[0154] The polarizer 2112 is used to convert unpolarized light into polarized light or change the polarization direction of polarized light.

For example, the third adhesive layer 2115 can be made of optical adhesive, double-sided grid adhesive, or the like.

[0158] In some embodiments, the display layer 211 further comprises a fourth adhesive layer 2116 disposed between the display functional layer 2113 and the protective layer 2114, for bonding the display functional layer 2113 and the protective layer 2114. For example, the fourth adhesive layer 2116 can be made of optical adhesive, double-sided grid adhesive, pressure sensitive adhesive (PSA), or the like.

[0159] It can be understood that, Figure 8 The stack structure of the display layer 211 shown is only exemplary, and the stack structure of the display layer of different types of electronic devices is also different, which will not be described one by one here.

[0160] In some embodiments, the conductive assembly 22 can be a single-layer structure, for example, the connecting portion 221 and the abutting portion 222 each comprise a single-layer material, for example, the connecting portion 221 comprises a support layer, and the abutting portion 222 comprises a conductive layer.

[0161] In other embodiments, the conductive assembly 22 is a stack structure, which will be introduced below in combination with Figure 9 and Figure 10 .

The first cover layer 223 and the second cover layer 225 can play a protective role or cover subsequent surface treatment. The second conductive layer 224 is used for conduction, in particular, the second conductive layer 224 of the abutting portion 222 is used for electrical connection with the elastic member 23.

[0163] Thus, the processing technology requirement of the conductive assembly 22 is low, and the local thinning of the conductive assembly 22 is realized due to the number of the stacked layers of the abutting portion 222 being less than the number of the stacked layers of the connecting portion 221, the space saved can provide space for the working height of the elastic member 23, which is conducive to reducing the thickness of the whole machine, and is beneficial to the inner cavity of the electronic device.

[0164] In some embodiments, the first cover film 223 and the second cover film 225 are made of polyimide.

[0165] Similarly to the first conductive layer 212, the second conductive layer 224 can be a single-layer structure or a multi-layer structure.

[0166] 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, copper, silver, etc., or a non-metal conductive material, such as carbon fiber, carbon nanotube, titanium carbide, graphene, zinc oxide, and some conductive polymer materials, conductive ceramic materials, etc.

[0167] For another example, when the second conductive layer 224 is a multi-layer structure, the second conductive layer 224 can include at least one metal layer. For example, Figure 9 The second conductive layer 224 can include a second metal layer 2242, a second dielectric layer 2241 and a third metal layer 2243 which are stacked, the second metal layer 2242 and the third metal layer 2243 are respectively arranged on two sides of the second dielectric layer 2241 in the thickness direction of the display screen, for example, the second metal layer 2242 is arranged on the side of the second dielectric layer 2241 close to the display screen 21, and the third metal layer 2243 is arranged on the side of the second dielectric layer 2241 close to the elastic member 23. For 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 mainly plays a supporting role for supporting the second metal layer 2242 and the third metal layer 2243.

[0168] The stacked structure design of the second conductive layer 224 can improve the strength and stability of the conductive assembly 22 while ensuring the conductive performance of the conductive assembly 22.

[0169] In the above embodiments, 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 the present application. Alternatively, the second conductive layer 224 can include the second metal layer 2242 or the third metal layer 2243.

[0170] In some embodiments, referring to Figure 10As shown, 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 near the display screen 21, and the second plating layer 2245 is disposed on the side of the third metal layer 2243 near the elastic member 23. For 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 improving at least one of the following properties: corrosion resistance, wear resistance, conductivity, or hardness.

[0171] 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. A silver plating layer can improve the conductivity of the conductive component 22. A nickel plating layer can improve the corrosion resistance and wear resistance of the conductive component 22. A gold plating layer can improve the conductive contact resistance and enhance conductivity.

[0172] As another example, see Figure 11 As shown, the connecting portion 221 includes a first cover film 223, a support layer 227, and a second cover film 225 stacked together. 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 closer to the display screen 21, and the second cover film 225 is disposed on the side of the support layer 227 closer to the elastic member 23. The abutting portion 222 includes a second conductive layer 224.

[0173] In other words, Figure 11 The stacked structure shown is Figure 9 The difference in the stacked structure shown is that the second conductive layer 224 in the connecting portion 221 is replaced by a support layer 227, and no metal layer is included. This can further reduce the thickness of the conductive component 22.

[0174] Of course, in some embodiments, the connecting portion 221 may include one of the first covering film 223 and the second covering film 225, or may not include the covering film, but only the support layer 227.

[0175] For example, the second conductive layer 224 may include a second metal layer 2242, a second dielectric layer 2241, and a third metal layer 2243 stacked together. 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 the side of the second dielectric layer 2241 closer to the display screen 21, and the third metal layer 2243 is disposed on the side of the second dielectric layer 2241 closer to the elastic member 23.

[0176] In some embodiments, Figure 11 In the illustrated laminated structure, the second conductive layer 224 can further include a second metal layer 2242, a third metal layer 2243, and a fourth metal layer 2244. Figure 10 The first plating layer 2244 is disposed on the side of the second metal layer 2242 close to the display screen 21, and the second plating layer 2245 is disposed on the side of the third metal layer 2243 close to the elastic member 23.

[0177] In some embodiments, the material of the second dielectric layer 2241 or the support layer 227 mentioned above can include at least one of polyimide (PI), TPU, polypropylene, PET, or polyvinylidene fluoride. The material of the second dielectric layer 2241 and the material of the support layer 227 can be the same or different, which is not limited in the present application.

[0178] In some embodiments, the second dielectric layer 2241 and the support layer 227 are located in the same layer, or 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 and the material of the support layer 227 are the same.

[0179] In some embodiments, referring to Figures 9 to 11 As shown, the connecting portion 221 can further include a fifth adhesive layer 226, which is disposed on the side of the first cover film 223 close to the display screen 21, and is used to bond the connecting portion 221 to the display screen 21 (for example, specifically to the first conductive layer 212). In some embodiments, the fifth adhesive layer 226 can also be referred to as a back adhesive. For example, the material of the fifth adhesive layer 226 can be optical adhesive, double-sided grid adhesive, or insulating foam adhesive, etc.

[0180] Figure 12 A schematic structural diagram of a conductive assembly provided by an embodiment of the present application is shown.

[0181] As shown in (a) in Figure 12 The gap H between the surface of the abutting portion 222 facing the display screen 21 and the surface of the display screen 21 facing the abutting portion 222. When the second end 232 of the elastic member 23 exerts a force on the abutting portion 222, the abutting portion 222 can move relative to the connecting portion 221 in the direction close to the display screen 21, eventually contact the display screen 21, and abut against the display screen 21 under the elastic force of the elastic member 23, realizing reliable electrical connection between the abutting portion 222 and the display screen 21. It can be understood that the gap H referred to here is formed after the conductive assembly 22 is assembled with the display screen 21. In the complete assembly state, after the elastic member 23 exerts a force on the abutting portion 222, the abutting portion 222 will move or deform in the thickness direction of the display screen in the gap H, and the gap H can be eliminated.

[0182] In other words, when the conductive component 22 is in its initial state (i.e., when it is not assembled with other components), that is, when the abutting part 222 is not in contact with the second end 232, there is a preset distance between the surface of the abutting part 222 facing the display screen 21 and the surface of the connecting part 221 facing the display screen 21. This preset distance is used when the conductive component 22 is in the assembled state, and the abutting part 222 moves along the thickness direction of the display screen in the gap H formed by the elastic member 23 until it abuts with the display screen 21.

[0183] Because there is a gap H between the abutting part 222 and the display screen 21, the force of contact between the abutting part 222 and the display screen 21 is provided only by the elastic element 23, which is highly controllable and facilitates the design of the size parameters and elastic force of the elastic element 23. Furthermore, the existence of gap H can offset errors generated during processing and assembly, avoiding or aggravating film printing problems. If there were no gap H between the abutting part 222 and the display screen 21, and if there were errors in the processing and assembly of the conductive component 22, the surface of the abutting part 222 facing the display screen 21 might be closer to the display screen 21 than the surface of the connecting part facing the display screen 21. In this case, after attaching the conductive component 22 to the display screen 21, the abutting part 222 would apply a certain pressure to a local area of ​​the display screen 21, which would affect the film printing.

[0184] In some embodiments, such as Figure 12 As shown in (b), the conductive component 22 may include a connecting portion 221, an abutting portion 222, and an elastic arm 228, with the elastic arm 228 connecting 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 towards the display screen 21. This helps to distribute the elastic force applied by the elastic member 23 to a larger surface, improving or avoiding film printing problems.

[0185] In some embodiments, the material of the elastic arm 228 may include at least one of PI, TPU, polypropylene, PET or polyvinylidene fluoride.

[0186] 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 abutment portion 222. Thus, the aforementioned gap H and the elastic arm 228 can be achieved through the differences in the stacked structure of each part of the conductive component 22, resulting in a simple structure and cost savings.

[0187] In some embodiments, the conductive assembly 22 can include two connecting portions 221 and an abutting portion 222 disposed between the two connecting portions 221. For distinction, one of the two connecting portions 221 is referred to as a first connecting portion, and the other is referred to as a second connecting portion. Thus, the two opposite ends of the abutting portion 222 are connected to the first connecting portion and the second connecting portion, respectively. In this way, the reliable connection between the conductive assembly 22 and the display screen 21 can be ensured.

[0188] In some embodiments, the conductive assembly 22 can include two elastic arms 228. For distinction, one of the two elastic arms 228 is referred to as a first elastic arm, and the other is referred to 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. In this way, the reliability of the overall movement of the abutting portion 222 can be ensured.

[0189] Figure 13 A schematic structural diagram of an elastic member is shown.

[0190] As shown in Figure 13 , the elastic member 23 includes a first end 231, a second end 232, and a deformation segment 233 located between the first end 231 and the second end 232 and capable of elastic deformation. Specifically, the deformation segment 233 is a curved sheet capable of storing and releasing energy by bending when an external force is applied to the deformation segment 233. For example, the shape of the deformation segment 233 can be arc-shaped. In the present embodiment, the first end 231 is a fixed end, the second end 232 is a free end, and the deformation segment 233 is capable of elastic deformation. Thus, the elastic member 23 is designed as a single cantilever, and the stability of the electrical connection can be ensured.

[0191] In some embodiments, the second end 232 faces a circular arc surface 2321 protruding toward the display screen 21. When the second end 232 abuts against the abutting portion 222, it is actually the circular arc surface 2321 that contacts the abutting portion 222. The design of the arc surface can ensure the reliability of the electrical connection between the second end 232 and the abutting portion 222.

[0192] In some embodiments, the second end 232 includes at least part of a sphere. For example, the second end 232 is spherical or hemispherical.

[0193] In some embodiments, the first end 231 includes a positioning portion 2311 for positioning the elastic member 23 when assembled. For example, the positioning portion 2311 can 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 disposed on the side of the first end 231 facing the metal member 24. Correspondingly, the metal member 24 includes a positioning portion design at the position corresponding to the first end 231, such as a corresponding design hole feature (e.g., a through hole or a blind hole) or a protrusion feature. When the metal member 24 includes a protrusion, the protrusion is disposed on the side of the metal member 24 facing the first end 231. For example, but not limited to, in actual applications, the positioning can be achieved by a positioning hole on the first end 231 and a positioning hole on the metal member 24, or by a protrusion on the first end 231 and a positioning hole on the metal member 24, or by a positioning hole on the first end 231 and a protrusion on the metal member 24. The positioning method of the elastic member 23 is not limited in the present application.

[0194] In some embodiments, the first end 231 includes a welding portion 2312 (as shown by the dashed line in the figure) for welding with the metal member 24. For example, the welding portion 2312 has a welding area of about 2 mm*2 mm. Compared with the welding area requirement of 2 mm*8 mm for the conductive foam, the elastic member 23 provided in the embodiments of the present application can occupy a smaller area to achieve welding with the metal member 24, saving space and facilitating the improvement of device layout space. Figure 13

[0195] Figure 14 A force-displacement curve of the elastic member 23 is shown. As shown in the figure, the vertical axis represents the reaction force generated by the applied force on the second end 232 of the elastic member 23, with the unit of newton (N). Figure 14

[0196] ​​As shown in the figure, when the displacement of the elastic element 23 is in the range of 0-0.6mm, the resulting reaction force is approximately 0-0.5N. In practical applications, the working height of the elastic element 23 can be controlled at around 0.25mm (e.g., between 0.2mm and 0.55mm). Compared to the 0.5mm-0.8mm working height required by conductive foam, the elastic element 23 provided in this embodiment occupies a significantly smaller dimension in the thickness direction of the display screen, which is beneficial for reducing the overall thickness. Correspondingly, the top force of the elastic element 23 can be controlled between 0.2N and 0.5N. Compared to the top force of over 1N generated by conductive foam, the top force generated by the elastic element 23 provided in this embodiment is significantly reduced, which is beneficial for improving the film printing problem and reducing the risk of screen delamination. Furthermore, electrical connections for displays typically require 5-8 grounding points. If conductive foam is used to electrically connect the display, the screen needs to be held in place by widening the bonding area and the adhesive application area to prevent it from detaching, which would increase the black borders on the screen. However, by using the elastic element 23 provided in this application to electrically connect the display, the elastic element 23 generates less force on the screen, which can greatly reduce the risk of screen detachment, improve screen reliability, and also improve the black borders on the screen, thereby enhancing the overall competitiveness of the device.

[0197] In addition, since the top screen force generated by the elastic element 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 display screen layers, so as to achieve a thinner and lighter design for electronic devices.

[0198] refer to Figure 6 In some embodiments, the electronic device 200 further includes a circuit board 25, on which the metal part 24 may be disposed.

[0199] In this application embodiment, the metal part 24 can be of various types.

[0200] As an example, see reference Figure 15 As shown in (a), the electronic device 200 may include a circuit board 25, and the metal part 24 may be a circuit board bracket, or a motherboard bracket.

[0201] As another example, see Figure 15 As shown in (b), the metal component 24 can be a shielding cover. The shielding cover can be used to protect the internal components of electronic devices from external radiation and interference. In some embodiments, the shielding cover can be disposed on the circuit board 25 and electrically connected to the circuit board 25. Since the elastic component 23 has a small working height requirement, connecting the elastic component 23 to the shielding cover can improve the utilization rate of the motherboard layout.

[0202] As another example, metal part 24 can be a board-to-board (BTB) connector bracket. BTB connectors are mainly used for connections between printed circuit boards (PCBs), directly connecting the power and signal of the board, effectively simplifying parallel stacked PCB applications. The BTB connector bracket is used to press-fit the BTB connectors, and can also be called a press-fit BTB bracket.

[0203] As yet another example, metal component 24 could be a mid-frame, for example... Figure 1 The middle frame 123 is shown.

[0204] In some embodiments, reference Figure 15 As shown in (a) and (b), the surface of the metal part 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 used to connect with the first end 231 of the elastic member 23. Since the metal part 24 occupies a small space, providing a recessed portion 241 on the metal part 24 to connect the elastic member 23 can reduce the overall height of the machine without affecting other components.

[0205] In some embodiments, such as Figure 15 As shown in (a), the projection of the first end 231 of the metal part 24 in the thickness direction of the display screen is located within the projection range of the recess 241 in the thickness direction of the display screen.

[0206] In some embodiments, such as Figure 15 As shown in (b), the projection of the metal part 24 in the thickness direction of the display screen is located within the projection range of the recess 241 in the thickness direction of the display screen.

[0207] In this application embodiment, there are multiple assembly methods for the display screen electrical connection scheme.

[0208] As an example, the elastic member 23 can be connected (e.g., welded) to the metal member 24 (e.g., a shielding cover, a metal bracket) first, and then the assembly (which can be referred to as an elastic assembly) of the elastic member 23 and the metal member 24 connected (e.g., welded) to the circuit board 25 (e.g., a mainboard). The conductive assembly 22 is connected (e.g., by adhesive back or adhesive foam) to the display screen 21, and specifically the connecting portion 221 of the conductive assembly 22 is connected to the layer (e.g., SCF layer or stainless steel layer, etc.) of the display screen 21 closest to the circuit board. Finally, the display screen 21 and the circuit board 25 are assembled together, and the second end 232 of the elastic member 23 abuts against the abutting portion 222 (e.g., the central region of the abutting portion 222) of the conductive assembly 22, for example, the second end 232 abuts against the second conductive layer 224 of the abutting portion 222. Since the abutting portion 222 is in contact with or has a small gap with the display screen 21, under the elastic force of the elastic member 23, the second end 232 exerts a force on the abutting portion 222 to deform the abutting portion 222 to abut against the display screen 21, thereby forming a complete electrical connection scheme.

[0209] As an example, the assembly method can be suitable for inverted electronic devices. Inverted refers to the way of assembling electronic devices, that is, the inner cavity is assembled first and the display screen is assembled last.

[0210] As another example, the elastic member 23 can be connected (e.g., welded) to the metal member 24 (e.g., a middle frame) first. The conductive assembly 22 is connected (e.g., by adhesive back or adhesive foam) to the display screen 21, and specifically the connecting portion 221 of the conductive assembly 22 is connected to the layer (e.g., SCF layer or stainless steel layer, etc.) of the display screen 21 closest to the circuit board. Then, the display screen 21 connected with the conductive assembly 22 and the metal member 24 connected with the elastic member 23 are assembled together, so that the second end 232 of the elastic member 23 abuts against the abutting portion 222 of the conductive assembly 22, for example, the second end 232 abuts against the second conductive layer 224 of the abutting portion 222. Finally, the circuit board 25 is assembled with the aforementioned assembly.

[0211] As an example, the assembly method can be suitable for inverted electronic devices. Inverted refers to the way of assembling electronic devices, that is, the inner cavity is assembled first and the display screen is assembled last.

[0212] In some embodiments, for the foldable electronic device with an outer screen, the inner screen is in a normal way, and the outer screen is in an inverted way.

[0213] In some embodiments, the display screen 21 can be a flexible screen (i.e., the screen can be bent and folded), or a rigid screen (i.e., the screen cannot be bent and folded).

[0214] In the embodiments of the present application, the display screen 21 can include a display area and a non-display area, and the non-display area surrounds the display area. The display area is an area that can display interface content, and the non-display area is an area that does not display interface content, which is usually black. For example, a cover plate (or screen frame or B shell) can be arranged on the display screen 21, and the window area of the cover plate is usually the display area, and the outer 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 to a back plate (or A shell), and the area of the display screen 21 that overlaps the back plate is usually the non-display area of the display screen 21, and the area of the display screen 21 that does not overlap the back plate is usually the display area of the display screen 21.

[0215] In some embodiments, the projection of the elastic member 23 in the thickness direction of the display screen 21 overlaps the projection of the display area of the display screen 21 in the thickness direction of the display screen 21. For example, the projection of the elastic member 23 in the thickness direction of the display screen 21 is located within the projection range of the display area of the display screen 21 in the thickness direction of the display screen 21.

[0216] In some embodiments, the projection of the conductive assembly 22 in the thickness direction of the display screen 21 overlaps the projection of the display area of the display screen 21 in the thickness direction of the display screen 21. For example, the projection of the conductive assembly 22 in the thickness direction of the display screen 21 is located within the projection range of the display area of the display screen 21 in the thickness direction of the display screen 21.

[0217] The elastic member 23 and the conductive assembly 22 can be arranged in the display area of the display screen, which is beneficial to flexible layout of the electrical connection points and can also reduce the black border formed by the non-display area.

[0218] In some embodiments, the display screen electrical connection scheme provided in the embodiments of the present application can be applied to foldable electronic devices, such as foldable mobile phones.

[0219] For example, the electronic device 200 can be a foldable electronic device. As shown in Figure 16 The electronic device 200 can include two display screens 21, namely a folding screen 21a and a non-folding screen 21b, where the folding screen 21a can also be referred to as an inner screen, and the non-folding screen 21b can also be referred to as an outer screen. For 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 embodiments of the present application can be applied to the inner screen 21a or the outer screen 21b. When applied to the outer screen 21b, the conductive assembly 22, the elastic member 23 and the metal member 24 are arranged between the inner screen 21a and the outer screen 21b.

[0220] In some embodiments, the electronic device 200 (specifically, the circuit board 25 mentioned above) can include a first circuit board 251 and a second circuit board 252, which are accommodated in the accommodation space formed by the shell 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. Among them, 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 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 the projection of the inner screen 21a in the screen thickness direction, and does not overlap the projection of the outer screen 21b in the screen thickness direction. It can be understood that the projection referred to here is the projection when the flexible screen is in the unfolded state.

[0221] It should be noted that the description of the thickness direction in the "thickness direction of the display screen", "thickness direction of the screen", "thickness direction of the electronic device" and the like related to the thickness direction described in the embodiments of the present application refers to the thickness direction when the display screen is in the unfolded state.

[0222] In some embodiments, the electronic device 200 can further include a system on chip (SOC) 261 and a radio frequency integrated circuit (RFIC) (also referred to as 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.

[0223] In some embodiments, the electronic device 200 can further include a first antenna and a second antenna, wherein the first antenna is arranged in the shell where the radio frequency chip 262 is located, and the second antenna is arranged in the shell where the system on chip 261 is located. That is, the first antenna, the radio frequency chip 262 and the first circuit board 251 can be located in the accommodation space formed by the first shell 121 as shown in Figure 2 , and the second antenna, the system on chip 261 and the second circuit board 252 can be located in the accommodation space formed by the second shell 122 as shown in Figure 2 . Such a layout design can improve space utilization, improve antenna flexibility and heat dissipation capacity. In addition, if the outer screen 21b is electrically connected by using the scheme provided in the present application, the spurious problem of the first antenna can be solved. In addition, this layout can improve the battery volume ratio, maximize the battery capacity in the extreme space, and improve the overall endurance of the electronic device, bringing a better experience for mobile office.

[0224] The application does not specifically limit the types of the first antenna and the second antenna. As an example but not limitation, the first antenna is a cellular antenna, and the second antenna is a short-range antenna.

[0225] In some embodiments, the system chip 261 and the radio frequency chip 262 can also be disposed on the same circuit board, such as the first circuit board 251 or the second circuit board 252.
