Description

Technical Field

[0001] The present application relates to the technical field of terminal equipment, and in particular to a screen and electronic equipment. Background Art

[0002] A foldable electronic device generally includes a first shell, a second shell, a hinge assembly, and a flexible screen, wherein the first shell and the second shell are rotatably connected via the hinge assembly, and the flexible screen covers the first shell, the second shell, and the hinge assembly. The electronic device may be provided with a portion of electronic devices on the inner side of the first shell, and another portion of electronic devices on the inner side of the second shell. When electrical signals need to be transmitted between the two portions of the electronic devices, this is generally achieved through a flexible circuit board that spans the hinge assembly. Since the electronic device has a folded state and an opened state, the flexible circuit board needs to be folded and opened along with the electronic device. Therefore, a space needs to be reserved around the hinge assembly of the electronic device to allow the flexible circuit board to deform, and the space is relatively large, resulting in a larger electronic device. Summary of the invention

[0003] The present application provides a screen and an electronic device.

[0004] In the first aspect, the embodiment of the present application provides a screen. The screen includes a display screen and a support member. The display screen includes a first part, a second part and a third part connected in sequence, and the second part can be deformed. The support member includes a first support portion, a second support portion and an electrical connection portion, the first support portion and the second support portion are rigid structural members, the electrical connection portion is a flexible structural member, the first support portion is fixed to the non-display surface of the first part, the second support portion is fixed to the non-display surface of the third part, and the electrical connection portion is connected between the first support portion and the second support portion. The first support portion includes a first circuit signal line, the second support portion includes a second circuit signal line, the electrical connection portion includes a third circuit signal line, and the third circuit signal line is electrically connected between the first circuit signal line and the second circuit signal line. Among them, the rigid structural member is relative to the flexible structural member, and is not easy to bend and deform. The structural member as a whole has a certain hardness and is not easy to deform, that is, it can be considered as a rigid structural member. If the rigid structural member includes a plurality of stacked structural layers, when there is a rigid structural layer, a flexible structural layer is also allowed to exist therein.

[0005] It can be understood that the first circuit signal line, the second circuit signal line, and the third circuit signal line can be used to transmit electrical signals, and the screen can also be used to transmit electrical signals. When the screen is applied to a foldable electronic device, the electrical signal transmission between two electronic components respectively arranged on different housings in the electronic device can be directly achieved through the support member of the screen, without the need to additionally provide a flexible circuit board for electrical signal transmission. During the arrangement of the internal components of the electronic device, there is no need to additionally reserve a space inside the electronic device to allow the flexible circuit board to deform, and the arrangement of the internal components of the electronic device is more compact, which is beneficial to reducing the volume of the electronic device.

[0006] In some possible implementation manners, the first support portion includes a first rigid circuit board, and the first rigid circuit board includes a first circuit signal line. The second support portion includes a second rigid circuit board, and the second rigid circuit board includes a second circuit signal line.

[0007] It can be understood that the first rigid circuit board can be used to transmit electrical signals and can also support the first part of the display screen. The second rigid circuit board can be used to transmit electrical signals and can also support the third part of the display screen.

[0008] In some possible implementation manners, the electrical connection portion is formed by a flexible circuit board, and the first rigid circuit board, the electrical connection portion, and the second rigid circuit board are respectively part of an integrated rigid-flexible circuit board. The rigid-flexible circuit board is formed by combining a flexible circuit board and a rigid circuit board through processes such as lamination and combining them together according to relevant process requirements to form a circuit board with the characteristics of an FPC and a PCB.

[0009] It can be understood that when using a rigid-flexible circuit board to transmit electrical signals, during the switching process of the electronic device between being opened and closed, the electrical connection portion is not easily disconnected from the first rigid circuit board or the second rigid circuit board. The connection reliability between the electrical connection portion and the first rigid circuit board and the second rigid circuit board is higher.

[0010] In some possible implementation manners, the first support portion further includes a first reinforcing member, the first reinforcing member is fixed between the non-display surface of the first rigid circuit board and the first part, and the hardness of the first reinforcing member is greater than the hardness of the first part. The second support portion further includes a second reinforcing member, the second reinforcing member is fixed between the non-display surface of the second rigid circuit board and the third part, and the hardness of the second reinforcing member is greater than the hardness of the third part. The electrical connection portion is connected between the first rigid circuit board and the second rigid circuit board.

[0011] It can be understood that the first reinforcing member can be used to further reinforce the support of the first part of the display screen. The second reinforcing member can be used to further reinforce the support of the third part of the display screen.

[0012] In some possible implementation manners, the support member further includes a third reinforcing member, the third reinforcing member is connected between the first reinforcing member and the second reinforcing member, and the third reinforcing member is provided with a first through hole. The third reinforcing member is fixed to the non-display surface of the second portion and is disposed opposite to the electrical connection portion.

[0013] In this way, the third reinforcing member can be used to support the second portion of the display screen. The third reinforcing member is provided with a first through hole, which can increase the bendable performance of the third reinforcing member.

[0014] In some possible implementation manners, the first reinforcing member, the second reinforcing member and the third reinforcing member are respectively a part of an integral metal plate member. In this way, the connection reliability between the first reinforcing member, the second reinforcing member and the third reinforcing member is relatively good.

[0015] In some possible implementation manners, the first support portion includes a first reinforcing member and a first flexible circuit board, the first reinforcing member is fixed between the first flexible circuit board and the non-display surface of the first portion, and the first flexible circuit board includes a first circuit signal line. The second support portion includes a second reinforcing member and a second flexible circuit board, the second reinforcing member is fixed between the second flexible circuit board and the non-display surface of the third portion, and the second flexible circuit board includes a second circuit signal line. The electrical connection portion is connected between the first flexible circuit board and the second flexible circuit board.

[0016] In this way, the first reinforcing member can be used to reinforce the first portion of the display screen. The second reinforcing member can be used to reinforce the third portion of the display screen. The first flexible circuit board, the second flexible circuit board and the electrical connection portion are used to transmit electrical signals.

[0017] In some possible implementation manners, the electrical connection portion, the first flexible circuit board and the second flexible circuit board are respectively a part of an integral flexible circuit board. In this way, the connection reliability between the electrical connection portion, the first flexible circuit board and the second flexible circuit board is relatively good, and during the folding and unfolding process of the screen, the electrical connection portion is not easily disconnected from the first flexible circuit board or the second flexible circuit board.

[0018] In some possible implementation manners, the first support portion and the second support portion are spaced apart, and along the direction from the first portion to the third portion, the length of the electrical connection portion is greater than the distance between the first support portion and the second support portion. In this way, when the screen switches between bending and flattening, the electrical connection portion has a redundant length, which is beneficial to reducing the risk of damage to the electrical connection portion during the stretching process. The distance between the first support portion and the second support portion refers to the distance between two adjacent side surfaces of the first support portion and the second support portion.

[0019] In some possible implementation manners, the difference between the length of the electrical connection part and the distance between the first support part and the second support part is in the range of.mm to.mm. In this way, the length of the electrical connection part is slightly greater than the distance between the first support part and the second support part, and there is no need to reserve a large activity space for the deformation of the electrical connection part.

[0020] In some possible implementation manners, the electrical connection part is provided with a second through hole, and the opening of the second through hole is arranged opposite to the second part.

[0021] In some possible implementation manners, the second circuit signal line includes a display signal line, the display signal line is electrically connected to the display screen, and the display signal line is used for transmitting display signals.

[0022] In some possible implementation manners, the first support part further includes a first electrical connector, and the first electrical connector is electrically connected to the first circuit signal line. The second support part further includes a second electrical connector, and the second electrical connector is electrically connected to the second circuit signal line.

[0023] It can be understood that the first electrical connector can be used to transmit the electrical signal on the first circuit signal line to other structural members. The second electrical connector can be used to transmit the electrical signal on the second circuit signal line to other structural members.

[0024] In a second aspect, an embodiment of the present application provides an electronic device. The electronic device includes a first housing, a second housing, a rotating shaft assembly, and a screen. The rotating shaft assembly is connected between the first housing and the second housing, and the first housing and the second housing are rotatably connected through the rotating shaft assembly. The first support part is arranged between the first part of the display screen and the first housing, the electrical connection part is arranged between the rotating shaft assembly and the second part of the display screen, and the second support part is arranged between the third part of the display screen and the second housing. The electronic device further includes a first main board and a second main board, the first main board and the second main board are respectively installed on the first housing and the second housing, the first main board is electrically connected to the first circuit signal line, and the second main board is electrically connected to the second circuit signal line.

[0025] It can be understood that the electrical signal transmission between two electronic devices respectively arranged on the first housing and the second housing is directly realized through the support member of the screen, and there is no need to additionally arrange a flexible circuit board for electrical signal transmission. During the arrangement of the internal components of the electronic device, there is no need to additionally reserve a space in the electronic device for allowing the flexible circuit board to deform, and the arrangement of the internal components of the electronic device is more compact, which is beneficial to reducing the volume of the electronic device.

[0026] Compared with the solution in which the electronic device sets up electrical connection components, and the rotating shaft assembly is provided with a wire threading channel, and the electrical connection components pass through the wire threading channel to achieve electrical signal transmission between two electronic devices respectively arranged on the first housing and the second housing. On the one hand, the rotating shaft assembly of the present application does not need to be provided with a wire threading channel, the structural complexity of the rotating shaft assembly is reduced, the process complexity of manufacturing the rotating shaft assembly is reduced, the reliability of the rotating shaft assembly can be improved, and at the same time, the thickness of the rotating shaft assembly in the Z-axis direction can also be reduced, which is beneficial to the thinning of the electronic device and reduces the assembly difficulty of the electronic device. On the other hand, the electrical signal transmission between two electronic devices respectively arranged on the first housing and the second housing is directly achieved through the support member of the screen. The number of circuit signal lines (including the first circuit signal line, the second circuit signal line and the third circuit signal line) arranged on the support member of the screen can be increased, and the cross-sectional size of the circuit signal lines is less restricted, which can reduce the impedance of the wire routing.

[0027] In some possible implementation manners, the electrical connection part is fixedly connected to the second part of the display screen, and the rotating shaft assembly is fixedly connected to the second part of the display screen. In this way, when the first housing and the second housing are closed and opened through the rotating shaft assembly, the second screen can be driven to bend. The first screen and the third screen overlap each other in the Z direction.

[0028] In some possible implementation manners, the rotating shaft assembly is fixedly connected to the non-display surface of the second part of the display screen through the second through hole of the electrical connection part.

[0029] In some possible implementation manners, the first circuit signal line includes at least one of an antenna radio frequency signal line, a power supply signal line, a camera signal line, an audio signal line, a clock signal line, and a chip read / write signal line. And / or the second circuit signal line includes at least one of an antenna radio frequency signal line, a power supply signal line, a display signal line, a camera signal line, an audio signal line, a clock signal line, and a chip read / write signal line.

[0030] It can be understood that the types and quantities of the signal lines included in the first circuit signal line and the second circuit signal line can be designed according to the electronic devices installed in the first housing and the second housing, and the types and quantities of the signal lines included in the first circuit signal line, the second circuit signal line, and the third circuit signal line can be different from each other.

The orientation terms mentioned in the embodiments of the present application, such as "top", "bottom", "upper", "lower", "left" or "right", etc., are only with reference to the direction of the attached drawings. Therefore, the orientation terms used are for better and clearer description and understanding of the embodiments of the present application, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the embodiments of the present application. Hereinafter, the terms "first", "second", etc. are used only for descriptive purposes and cannot be understood as implying or indicating relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In addition, "plurality" means at least two.

[0046] The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0047] Figure 1 It is a schematic structural diagram of the electronic device 1000 provided by the embodiment of the present application in an open state. It should be noted that the figure only schematically shows some components included in the electronic device 1000, and the actual size, actual position, and actual structure of these components are not limited by the figure. The following accompanying drawings also only schematically show some components, and the actual size, actual position, and actual structure of these components are not limited by the following accompanying drawings either. Specifically, it will not be elaborated further below.

Figure 1 The electronic device 1000 in the illustrated embodiment is described by taking a foldable mobile phone as an example. Among them, for the convenience of description, as Figure 1 shown, the width direction of the electronic device 1000 is defined as the X-axis. The length direction of the electronic device 1000 is defined as the Y-axis. The thickness direction of the electronic device 1000 is defined as the Z-axis. In other embodiments, the coordinate system can also be flexibly set according to other requirements.

[0050] As Figure 1 , Figure 2 and Figure 3 shown, the electronic device 1000 includes a screen 100, a housing 200, and a rotating shaft assembly 300. The housing 200 includes a first housing 210 and a second housing 220. The rotating shaft assembly 300 is connected between the first housing 210 and the second housing 220, and the first housing 210 and the second housing 220 are rotatably connected through the rotating shaft assembly 300. Thus, the first housing 210 and the second housing 220 can be switched between a closed state and an open state. Among them, Figure 1 illustrates that the electronic device 1000 is in an open state. Figure 2 illustrates that the electronic device 1000 is in a closed state.

[0052] When the electronic device 1000 is in an open state, the first screen 101, the second screen 102, and the third screen 103 are approximately 180° (allowing slight deviations, such as 165°, 177°, or 185°). At this time, the screen 100 has a continuous large display area, that is, the screen 100 can achieve large-screen display, and the user experience is better. When the electronic device 1000 is in a closed state, the screens 100 are folded together. Specifically, the second screen 102 is bent. The first screen 101 and the third screen 103 overlap each other in the Z direction. At this time, the planar size of the electronic device 1000 is smaller, which is convenient for users to carry and store.

[0053] In addition, Figure 2 illustrates that when the electronic device 1000 is in a closed state, the first screen 101 and the third screen 103 can be located between the first housing 210 and the second housing 220, that is, the screen 100 can be folded inward. In other embodiments, when the electronic device 1000 is in a closed state, the first housing 210 and the second housing 220 can also be located between the first screen 101 and the third screen 103, that is, the screen 100 can be folded outward. Specifically, this embodiment is not limited.

[0054] In addition, the attached Figure 1 and the attached Figure 2 both illustrate that the electronic device 1000 can be folded once. In other embodiments, the electronic device 1000 can also be folded multiple times, that is, the screen 100 can include multiple bendable parts. The multi-fold electronic device 1000 will be introduced later through the accompanying drawings, and will not be elaborated here.

The light reflected by an object to be photographed from the outside generates an optical image through the lens and is projected onto the photosensitive element. The photosensitive element is used to convert the optical signal into an electrical signal. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. In some embodiments, the electronic device 1000 can include one or more cameras. Among them, the camera can implement functions such as autofocus function and optical image stabilization function.

Exemplarily, the image signal processor in the processor can be used to control the camera to take pictures or record videos, and is also used to convert the electrical signal output by the camera into an image signal.

[0064] The audio module is used to convert digital audio information into an analog audio signal for output, and is also used to convert an analog audio input into digital audio signal. The audio module can also be used to encode and decode audio signals.

[0065] The internal memory can be used to store computer-executable program code, and the executable program code includes instructions. The processor executes various functional applications and data processing of the electronic device 1000 by running the instructions stored in the internal memory. The internal memory can include a program storage area and a data storage area. Among them, the program storage area can store an operating system, application programs required for at least one function (such as a sound playback function, an image playback function, etc.). The data storage area can store data created during the use of the electronic device 1000 (such as audio data, phone book, etc.). In some embodiments, the internal memory can be a chip.

[0066] The speaker, also known as the "loudspeaker", is used to convert an audio electrical signal into a sound signal. The electronic device 1000 can listen to music or hands-free calls through the speaker.

[0067] The receiver, also known as the "earpiece", is used to convert an audio electrical signal into a sound signal. When the electronic device 1000 answers a call or a voice message, the voice can be listened to by placing the receiver close to the human ear.

[0068] The microphone, also known as the "microphone" or "transmitter", is used to convert a sound signal into an electrical signal. When making a call or sending a voice message, the user can speak close to the microphone with the mouth to input the sound signal into the microphone. The electronic device 1000 can be provided with at least one microphone. In some other embodiments, the electronic device 1000 can be provided with two microphones, which can not only collect sound signals but also achieve a noise reduction function. In some other embodiments, the electronic device 1000 can also be provided with three, four or more microphones to achieve functions such as collecting sound signals, noise reduction, identifying the sound source, and realizing a directional recording function.

[0069] The sensor module can include a pressure sensor, a gyroscope sensor, a barometric pressure sensor, an acceleration sensor, a distance sensor, a proximity light sensor, a fingerprint sensor, a temperature sensor, a touch sensor, an ambient light sensor, a bone conduction sensor, etc.

[0070] Exemplarily, the pressure sensor can be disposed on the screen 100. When there is a touch operation on the screen 100, the electronic device 1000 can detect the intensity of the touch operation according to the pressure sensor. The electronic device 1000 can also calculate the position of the touch according to the detection signal of the pressure sensor.

[0071] The gyroscope sensor can be used to determine the motion posture of the electronic device 1000. The barometric pressure value measured by the barometric pressure sensor can be used to calculate the altitude and assist the electronic device 1000 in positioning and navigation.

[0072] The acceleration sensor can detect the magnitude of the acceleration of the electronic device 1000 in various directions (generally three axes). When the electronic device 1000 is stationary, the magnitude and direction of gravity can be detected. It can also be used to identify the posture of the electronic device 1000 and is applied to applications such as horizontal and vertical screen switching and pedometers.

[0073] The distance sensor is used to measure distance. The electronic device 1000 can measure distance through infrared or laser. In some embodiments, when shooting a scene, the electronic device 1000 can use the distance sensor to measure distance to achieve rapid focusing.

[0074] The proximity light sensor may include, for example, a light-emitting diode and a light detector, such as a photodiode. The light-emitting diode can be an infrared light-emitting diode. The electronic device 1000 emits infrared light outward through the light-emitting diode. The electronic device 1000 uses the photodiode to detect the infrared reflected light from nearby objects. When sufficient reflected light is detected, it can be determined that there is an object near the electronic device 1000. When insufficient reflected light is detected, the electronic device 1000 can determine that there is no object near the electronic device 1000.

[0075] The ambient light sensor can be used to sense the ambient light brightness. The electronic device 1000 can adaptively adjust the screen 100 brightness according to the sensed ambient light brightness. The ambient light sensor can also be used to automatically adjust the white balance when taking pictures. The ambient light sensor can also cooperate with the proximity light sensor to detect whether the electronic device 1000 is in the pocket to prevent accidental touch.

[0076] The fingerprint sensor can be used to collect fingerprints. The electronic device 1000 can use the collected fingerprint characteristics to achieve fingerprint unlocking, access application locks, fingerprint photography, fingerprint answering calls, etc.

The bone conduction sensor can also contact the human pulse and receive blood pressure pulsation signals. In some embodiments, the bone conduction sensor can also be disposed in the earphone to form a bone conduction earphone. The audio module can parse the voice signal based on the vibration signals of the vibrating bone mass of the vocal part acquired by the bone conduction sensor to implement the voice function. The processor can parse the heart rate information based on the blood pressure pulsation signals acquired by the bone conduction sensor to implement the heart rate detection function.

[0078] In other embodiments, the electronic device 1000 may have more or fewer components than those described above.

[0079] It can be understood that the designer can install different electronic devices 500 on the first housing 210 or the second housing 220 according to requirements. For example, a battery, an antenna, a charging management module, a camera module 510, a processor, and an audio module can be installed on the first housing 210 and electrically connected to the first main board 410. An internal memory, a speaker, a receiver, and a microphone can be installed on the second housing 220 and electrically connected to the second main board 420. Exemplarily, the electronic device 500 and the first main board 410 or the electronic device 500 and the second main board 420 can be electrically connected by arranging a flexible circuit board.

[0080] The number of the first main boards 410 can be one or multiple. The number of the second main boards 420 can be one or multiple. Figure 3 Only one first main board 410 and one second main board 420 are schematically shown in []. Exemplarily, when the number of the first main boards 410 is multiple, the multiple first main boards 410 can be used to electrically connect different electronic devices 500, and then transmit different electrical signals.

[0081] When the electronic device 1000 works, the electronic devices 500 on both sides can be electrically connected through the first main board 410, the screen 100, and the second main board 420. The specific electrical connection method will be specifically introduced by combining the drawings below.

[0082] Figure 4 is Figure 3 a schematic exploded view of an implementation manner of the screen 100 shown in [].

[0083] As Figure 4 shown, the screen 100 can include a display screen 10 and a support member 20. The display screen 10 is used for displaying images. The support member 20 is used for supporting the display screen 10. The display screen 10 can adopt a flexible display screen. For example, the display screen 10 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode display screen, a microorganic light-emitting diode display screen, a micro organic light-emitting diode display screen, or a quantum dot light emitting diodes (QLED) display screen.

[0084] The display screen 10 includes a display surface 11 and a non-display surface 12. The display surface 11 and the non-display surface 12 are arranged opposite to each other. The display surface 11 of the display screen 10 refers to a side surface of the display screen 10 that can display an image when the user normally uses the electronic device 1000. The display surface 11 faces the user, and the non-display surface 12 faces the inside of the electronic device 1000. The support member 20 is fixed to the non-display surface 12 of the display screen 10. In some embodiments, the support member 20 can be fixed to the non-display surface 12 of the display screen 10 by gluing.

[0085] Exemplarily, the display screen 10 includes a first portion 13, a second portion 14, and a third portion 15 connected in sequence. The second portion 14 is connected between the first portion 13 and the third portion 15. Exemplarily, Figure 1 Take the arrangement of the first part 13, the second part 14 and the third part 15 along the Y-axis direction as an example for illustration. The second part 14 can be deformed. When the electronic device 1000 is in an open state, the first part 13, the second part 14 and the third part 15 are approximately 180° (slight deviation is allowed, such as 165°, 177° or 185°). When the electronic device 1000 is in a closed state, the second part 14 is bent, and the first part 13 and the third part 15 are arranged facing each other.

[0086] The support member 20 may include a first support portion 21, a second support portion 22 and an electrical connection portion 23. The electrical connection portion 23 is connected between the first support portion 21 and the second support portion 22. The first support portion 21 may be fixed to the non-display surface of the first portion 13. The second support portion 22 may be fixed to the non-display surface of the third portion 15. The first support portion 21 and the second support portion 22 are rigid structural members, and the electrical connection portion 23 is a flexible structural member. In this way, the first support portion 21 and the second support portion 22 may be used to support the first portion 13 and the third portion 15 of the display screen 10. During the process of opening or closing the electronic device 1000, the electrical connection portion 23 may have better bending performance. Among them, the non-display surface of the first portion 13 is a part of the non-display surface 12 of the display screen 10. The non-display surface of the third portion 15 is a part of the non-display surface 12 of the display screen 10.

[0087] It is understandable that a rigid structural part is relative to a flexible structural part and is not prone to bending or deformation. A structural part as a whole has a certain hardness and is not prone to deformation, which can be considered a rigid structural part. If a rigid structural part includes multiple stacked structural layers, a flexible structural layer is also allowed to exist in the rigid structural layer.

[0088] In some embodiments, the hardness of the first support portion 21 and the second support portion 22 is greater than the hardness of the electrical connection portion 23. The bendability of the electrical connection portion 23 is greater than the bendability of the first support portion 21 and the second support portion 22.

[0089] The first support portion 21 and the first part 13 of the display screen 10 can form a first screen 101. The electrical connection portion 23 and the second part 14 of the display screen 10 can form a second screen 102. The second support portion 22 and the third part 15 of the display screen 10 can form a third screen 103. In the Z-axis direction, the first support portion 21 is disposed between the first part 13 of the display screen 10 and the first housing 210, the electrical connection portion 23 is disposed between the rotating shaft assembly 300 and the second part 14 of the display screen 10, and the second support portion 22 is disposed between the third part 15 of the display screen 10 and the second housing 220.

[0090] Figure 5 It is an assembly schematic diagram of an embodiment of the first rigid circuit board 212, the second rigid circuit board 222, the electrical connection portion 23, the first main board 410, and the second main board 420 from another angle.

[0091] As Figure 4 and Figure 5 shown, the first support portion 21 includes a first circuit signal line 211 ( Figure 5 schematically indicated by a dotted line in Figure 5 ), the second support portion 22 includes a second circuit signal line 221 ( Figure 5 schematically indicated by a dotted line in

[0092] Exemplarily, the first support portion 21 may include a first rigid circuit board 212 and a first reinforcing member 213. The first reinforcing member 213 may be fixed between the non-display surface of the first rigid circuit board 212 and the first portion 13. The hardness of the first reinforcing member 213 may be greater than the hardness of the first portion 13. The second support portion 22 may include a second rigid circuit board 222 and a second reinforcing member 223. The second reinforcing member 223 may be fixed between the non-display surface of the second rigid circuit board 222 and the third portion 15. The electrical connection portion 23 may be connected between the first rigid circuit board 212 and the second rigid circuit board 222. The hardness of the second reinforcing member 223 may be greater than the hardness of the third portion 15. The first rigid circuit board 212 may include a first circuit signal line 211. The second rigid circuit board 222 may include a second circuit signal line 221. In this way, the first rigid circuit board 212 can be used for electrical signal transmission. The second rigid circuit board 222 can be used for electrical signal transmission. The first reinforcing member 213 can be used to further reinforce the support of the first portion 13 of the display screen 10. The second reinforcing member 223 can be used to further reinforce the support of the third portion 15 of the display screen 10.

[0093] In some embodiments, the electrical connection portion 23 is formed by a flexible printed circuit board (FPCB). In other embodiments, the electrical connection portion 23 can also be formed by a cable.

[0094] In some embodiments, the first rigid circuit board 212 may employ a printed circuit board (PCB). The first rigid circuit board 212 may include a substrate and metal traces embedded in the substrate. The metal traces embedded in the substrate can be used to transmit electrical signals, that is, the traces are the first circuit signal lines 211.

[0095] In some embodiments, the second rigid circuit board 222 may employ a printed circuit board (PCB). The second rigid circuit board 222 may include a substrate and traces embedded in the substrate. The traces embedded in the substrate can be used to transmit electrical signals, and the traces are the second circuit signal lines 221.

[0096] In some embodiments, the first rigid circuit board 212, the electrical connection portion 23, and the second rigid circuit board 222 are respectively part of an integrated flexible-rigid circuit board. A flexible-rigid circuit board is formed by combining a flexible circuit board and a rigid circuit board through processes such as lamination and assembling them together according to relevant process requirements, resulting in a circuit board with both FPC and PCB characteristics. It can be understood that when using a flexible-rigid circuit board for transmitting electrical signals, during the switching process of the opening and closing of the electronic device 1000, the electrical connection portion 23 is not easily disconnected from the first rigid circuit board 212 or the second rigid circuit board 222. The connection reliability between the electrical connection portion 23 and the first rigid circuit board 212 and the second rigid circuit board 222 is higher.

[0097] In other embodiments, the electrical connection portion 23 can be electrically connected between the first circuit signal line 211 and the second circuit signal line 221 by soldering or by providing some electrical connectors.

[0098] When two electronic devices 500 respectively disposed on the first housing 210 and the second housing 220 need to transmit electrical signals, the two electronic devices 500 respectively disposed on the first housing 210 and the second housing 220 can be correspondingly electrically connected to the first main board 410 or the second main board 420 on that side. The first main board 410 is electrically connected to the first circuit signal line 211 on the first support portion 21, and the second main board 420 is electrically connected to the second circuit signal line 221 on the second support portion 22. In this way, the electronic devices 500 respectively installed on the first housing 210 and the second housing 220 can be electrically connected through the first main board 410, the first circuit signal line 211, the third circuit signal line 231, the second circuit signal line 221, and the second main board 420.

[0099] It can be understood that the electrical signal transmission between the two electronic devices 500 respectively disposed on the first housing 210 and the second housing 220 is directly achieved through the support member 20 of the screen 100, without the need to additionally provide a flexible circuit board for electrical signal transmission. During the arrangement of the internal components of the electronic device 1000, there is no need to additionally reserve a space inside the electronic device 1000 to allow the flexible circuit board to deform, and the arrangement of the internal components of the electronic device 1000 is more compact, which is beneficial to reducing the volume of the electronic device 1000.

[0100] In addition, compared with the solution in which the electronic device 1000 sets up electrical connection components, and the rotating shaft assembly 300 is provided with a wire threading channel, and the electrical connection components pass through the wire threading channel to achieve electrical signal transmission between two electronic devices 500 respectively arranged on the first housing 210 and the second housing 220. On the one hand, the rotating shaft assembly 300 of the present application does not need to be provided with a wire threading channel, the complexity of the structure of the rotating shaft assembly 300 is reduced, the complexity of the process for manufacturing the rotating shaft assembly 300 is reduced, the reliability of the rotating shaft assembly 300 can be improved, and at the same time, the thickness of the rotating shaft assembly 300 in the Z-axis direction can also be reduced, which is beneficial to the thinning of the electronic device 1000 and reduces the assembly difficulty of the electronic device 1000. On the other hand, the electrical signal transmission between two electronic devices 500 respectively arranged on the first housing 210 and the second housing 220 is directly realized through the support member 20 of the screen 100. The number of circuit signal lines (including the first circuit signal line 211, the second circuit signal line 221, and the third circuit signal line 231) arranged on the support member 20 of the screen 100 can be increased, and the cross-sectional size of the circuit signal lines is less restricted, which can reduce the impedance of the wire routing.

[0101] In some embodiments, the first support portion 21 may further include a first electrical connector 214, and the first electrical connector 214 is electrically connected to the first circuit signal line 211. The first electrical connector 214 may be electrically connected to the first main board 410 for electrical signal transmission between the first circuit signal line 211 and the first main board 410. Exemplarily, the first electrical connector 214 may be a board-to-board connector (BTB).

[0102] In some embodiments, the first electrical connector 214 may be directly fixedly connected to the substrate of the first rigid circuit board 212 and electrically connected to the first circuit signal line 211; or it may be connected to the first rigid circuit board 212 through a flexible circuit board and electrically connected to the first circuit signal line 211.

[0103] In some embodiments, the first main board 410 may be provided with a female seat of a board-to-board connector (BTB) (not shown in the figure), and the first electrical connector 214 is a male head of the board-to-board connector. In this way, the first electrical connector 214 can cooperate with the female seat of the board-to-board connector on the first main board 410 to achieve electrical signal transmission. In other embodiments, the first electrical connector 214 may also be a zero insertion force connector (ZIF), and the present application does not make any restrictions. The number of the first electrical connectors 214 may be one or multiple.

[0104] In some embodiments, the second support portion 22 may further include a second electrical connector 224, and the second electrical connector 224 is electrically connected to the second circuit signal line 221. The second electrical connector 224 may be electrically connected to the second main board 420 for electrical signal transmission between the second circuit signal line 221 and the second main board 420. For the specific setting of the second electrical connector 224, reference may be made to the setting of the first electrical connector 214, which will not be elaborated here.

[0105] The number of the second electrical connectors 224 may be one or more. ( Figure 5 Two second electrical connectors 224 are illustrated in [].) It can be understood that when multiple second electrical connectors 224 are provided, different second electrical connectors 224 may be electrically connected to different types of second circuit signal lines 221 for outputting different types of electrical signals. Exemplarily, when the number of the second electrical connectors 224 is multiple, the number of the second main boards 420 may also be multiple, and the multiple second electrical connectors 224 and the multiple second main boards 420 may be electrically connected in one-to-one correspondence, so as to transmit the electrical signals of different electronic devices 500.

[0106] Figure 6 FIG. [] is a schematic diagram of the electrical connection relationship of an embodiment between the camera module 510 and the image processor 520.

[0107] As Figure 5 and Figure 6 shown, taking the electrical signal transmission when the camera module 510 of the electronic device 1000 takes pictures as an example, a specific introduction is made as follows:

[0108] The camera module 510 can be mounted on the first housing 210. The image processor 520 can be mounted on the second housing 220. The camera module 510 can be electrically connected to the first main board 410. The first main board 410 is electrically connected to the first circuit signal line 211 on the first support portion 21. The image processor 520 can be electrically connected to the second main board 420. The second main board 420 is electrically connected to the second circuit signal line 221 on the second support portion 22. The first circuit signal line 211 can include a camera signal line 2111 (hereinafter referred to as the first camera signal line 2111 for convenience of distinction). The second circuit signal line 221 can include a camera signal line 2211 (hereinafter referred to as the second camera signal line 2211). The third circuit signal line 231 can include a camera signal line 2311 (hereinafter referred to as the third camera signal line 2311). The third camera signal line 2311 is electrically connected between the first camera signal line 2111 and the second camera signal line 2211. The signal generated by the camera module 510 after receiving external light can be transmitted to the image processor 520 through the first main board 410, the first camera signal line 2111, the third camera signal line 2311, the second camera signal line 2211, and the second main board 420 in sequence. The image processor 520 converts the electrical signal output by the camera module 510 into an image signal.

[0109] In some embodiments, the second circuit signal line 221 may further include a display signal line 2212 ( Figure 5 schematically shown by a dashed line in the figure), the display signal line 2212 is electrically connected to the display screen 10, and the display signal line 2212 is used to transmit a display signal. The second main board 420 can be electrically connected to the display signal line 2212. In this way, the image signal converted from the electrical signal output by the camera by the image processor can be transmitted to the display screen 10 through the second main board 420 and the display signal line 2212 on the second support portion 22, and finally displayed on the display screen 10. In other embodiments, the first circuit signal line 211 may also include a display signal line, and the display signal line included in the first circuit signal line 211 is electrically connected to the display screen 10.

[0110] The number of the first circuit signal lines 211 can be multiple or one. Exemplarily, the first circuit signal lines 211 can further include at least one of an antenna radio frequency signal line, a power supply signal line, an audio signal line, a clock signal line, and a chip read / write signal line. The antenna radio frequency signal line can be electrically connected to an antenna for transmitting antenna signals. The power supply signal line can be electrically connected to an electronic device 500 that needs to be powered for transmitting power. The audio signal line can be electrically connected to electronic devices 500 such as a speaker, an audio module, a receiver, and a handset for transmitting audio information. The clock signal line and the chip read / write signal line can be electrically connected to an internal memory for transmitting clock signals and chip read / write signals. When the number of the first circuit signal lines 211 is multiple, the multiple first circuit signal lines 211 are arranged at intervals and insulated from each other.

[0111] The number of the second circuit signal lines 221 can be multiple or one. Exemplarily, the second circuit signal lines 221 can further include at least one of an antenna radio frequency signal line, a power supply signal line, a display signal line, an audio signal line, a clock signal line, and a chip read / write signal line.

[0112] The number of the third circuit signal lines 231 can be multiple or one. Exemplarily, the third circuit signal lines 231 can include at least one of an antenna radio frequency signal line, a power supply signal line, a display signal line, a camera signal line, an audio signal line, a clock signal line, and a chip read / write signal line. When the third circuit signal lines 231 are electrically connected between the first circuit signal lines 211 and the second circuit signal lines 221, the corresponding types of circuit signal lines are correspondingly connected (refer to the connection method of the camera signal line in the foregoing), and are insulated from other circuit signal lines.

[0113] It can be understood that the types and numbers of the signal lines included in the first circuit signal lines 211, the second circuit signal lines 221, and the third circuit signal lines 231 can be designed according to the electronic devices 500 installed in the first housing 210 and the second housing 220, and the types and numbers of the signal lines included in the first circuit signal lines 211, the second circuit signal lines 221, and the third circuit signal lines 231 can be different from each other.

[0114] Such as Figure 4As shown, the first support portion 21 and the second support portion 22 are spaced apart. The length of the electrical connection portion 23 is greater than the distance between the first support portion 21 and the second support portion 22 in the direction of the first portion 13 towards the third portion 15. In this way, during the opening and closing of the electronic device 1000, the screen 100 switches between bending and flattening, and the electrical connection portion 23 has a redundant length, which helps to reduce the risk of damage to the electrical connection portion 23 during the stretching process. The distance between the first support portion 21 and the second support portion 22 refers to the distance between two adjacent sides of the first support portion 21 and the second support portion 22.

[0115] Exemplarily, the first rigid circuit board 212 and the second rigid circuit board 222 are spaced apart. The length of the electrical connection portion 23 is greater than the distance H in the Y-axis direction between the first rigid circuit board 212 and the second rigid circuit board 222 ( Figure 5 schematically indicated by the marked line in). In this way, when the screen 100 switches between bending and flattening, the gap between the first rigid circuit board 212 and the second rigid circuit board 222 can serve as an active space reserved for the deformation of the electrical connection portion 23.

[0116] In some embodiments, the difference between the length of the electrical connection portion 23 and the distance between the first support portion 21 and the second support portion 22 is in the range of 0.3 mm to 0.5 mm. The length of the electrical connection portion 23 is slightly greater than the distance between the first support portion 21 and the second support portion 22, and there is no need to reserve a large active space for the deformation of the electrical connection portion 23.

[0117] In some embodiments, the material of the first reinforcement member 213 can be a metal material, such as stainless steel, copper, titanium alloy, aluminum alloy, etc., or other composite materials, such as glass fiber, carbon fiber, etc.

[0118] In some embodiments, the thickness of the first reinforcement member 213 (i.e., the height of the first reinforcement member 213 in the Z-axis direction) can be in the range of 0.01 mm to 0.1 mm. Exemplarily, the thickness of the first reinforcement member 213 can be in the range of 0.02 mm to 0.03 mm.

[0119] In some embodiments, the material of the second reinforcement member 223 can be a metal material, such as stainless steel, titanium alloy, aluminum alloy, etc., or other composite materials, such as glass fiber, carbon fiber, etc.

[0120] Figure 7 is Figure 1 a partial cross-sectional view of an embodiment of the electronic device shown in at the section line A-A.

[0121] As Figure 5 and Figure 7As shown, the electrical connection part 23 is provided with a second through hole 232, and the opening of the second through hole 232 is arranged opposite to the second part 14. The rotating shaft assembly 300 can be fixedly connected to the non-display surface of the second part 14 of the display screen 10 through the second through hole 232. Exemplarily, the rotating shaft assembly 300 can be fixedly connected to the non-display surface 12 of the second part 14 of the display screen 10 by means of gluing. Figure 7 The dispensing structure 600 is schematically shown in it.

[0122] In some embodiments, the electrical connection part 23 can also be fixedly connected to the second part 14 of the display screen 10. Exemplarily, the electrical connection part 23 can be fixedly connected to the non-display surface of the second part 14 of the display screen 10 by means of gluing. The non-display surface of the second part 14 is a part of the non-display surface 12 of the display screen 10. In some embodiments, the electrical connection part 23 can also be fixedly connected to the rotating shaft assembly 300.

[0123] As Figure 4 shown, the support member 20 can further include a third reinforcing member 24. The third reinforcing member 24 can be connected between the first reinforcing member 213 and the second reinforcing member 223. The third reinforcing member 24 can be fixed to the non-display surface 12 of the second part 14 and is arranged opposite to the electrical connection part 23. The third reinforcing member 24 can be used to support the second part 14 of the display screen 10.

[0124] In some embodiments, the material of the third reinforcing member 24 can be a metal material, such as stainless steel, copper, titanium alloy, aluminum alloy, etc., or other composite materials, such as glass fiber, carbon fiber, etc.

[0125] In some embodiments, the first reinforcing member 213, the second reinforcing member 223 and the third reinforcing member 24 are respectively a part of an integral metal plate member. In other words, the first reinforcing member 213, the second reinforcing member 223 and the third reinforcing member 24 are an integral metal plate member. In this way, the connection reliability between the first reinforcing member 213, the second reinforcing member 223 and the third reinforcing member 24 is relatively good, and it is not easy to disconnect between the first reinforcing member 213, the second reinforcing member 223 and the third reinforcing member 24 during the opening and closing process of the electronic device 1000.

[0126] Figure 8 is Figure 4 a schematic structural diagram of an embodiment of the third reinforcing member 24 shown in it.

[0127] As Figure 8As shown, the third reinforcing member 24 may be provided with a first through hole 241. Exemplarily, the first through hole 241 may penetrate the third reinforcing member 24 along the Z-axis direction. It can be understood that by providing the first through hole 241, the bendability of the third reinforcing member 24 can be increased. During the opening and closing processes of the electronic device 1000, the third reinforcing member 24 has better flexibility and has less influence on the bending of the display screen 10. In other embodiments, the first through hole 241 may also be in the form of a groove.

[0128] In some embodiments, the number of the first through holes 241 may be multiple. Exemplarily, the multiple first through holes 241 are arranged at intervals along the Y-axis direction.

[0129] In some embodiments, in the X-Y plane, the shape of the first through hole 241 may be Figure 7 in the shape of a bamboo joint as shown. In the Y-axis direction, the widths of the two ends of the first through hole 241 are greater than the width of the middle part. This shape may also be referred to as a dumbbell shape. In other embodiments, the shape of the first through hole 241 may also be rectangular, racetrack-shaped, etc. The number, arrangement manner, and shape of the first through holes 241 may be adaptively set according to requirements, and the present application does not make any limitations.

[0130] Figure 9 is Figure 4 a schematic structural diagram of another embodiment of the third reinforcing member 24 shown in

[0131] As Figure 9 shown, the third reinforcing member 24 may also be provided with a third through hole 242. The length of the third through hole 242 in the Y-axis direction is greater than the length of the third through hole 242 in the X-axis direction.

[0132] In some embodiments, the number of the third through holes 242 may be multiple. Exemplarily, the multiple third through holes 242 are arranged at intervals along the X-axis direction.

[0133] In some embodiments, the number of the first through holes 241 may be multiple. A part of the first through holes 241 is located on the side of the third through hole 242 close to the first reinforcing member 213, and another part of the first through holes 241 is located on the side of the third through hole 242 close to the second reinforcing member 223.

[0134] In some embodiments, the first support portion 21 may not be provided with the first reinforcing member 213. The first rigid circuit board 212 may be used to transmit electrical signals and may also support the first part 13 of the display screen 10.

[0135] In some embodiments, the second support portion 22 may not be provided with the second reinforcement member 223. The second rigid circuit board 222 can be used to transmit electrical signals and can also support the third portion 15 of the display screen 10.

[0136] In some embodiments, the same technical content as that of the screen 100 in the previous embodiments will not be described in detail.

[0137] The first support portion 21 may include a first reinforcement member 213 and a first flexible circuit board (not shown in the figure). The first reinforcement member 213 is fixed between the first flexible circuit board and the non-display surface of the first portion 13. The second support portion 22 includes a second reinforcement member 223 and a second flexible circuit board (not shown in the figure), and the second reinforcement member 223 is fixed between the second flexible circuit board and the non-display surface of the third portion 15. The electrical connection portion 23 can be connected between the first flexible circuit board and the second flexible circuit board. The first flexible circuit board includes a first circuit signal line 211. The second flexible circuit board includes a second circuit signal line 221.

[0138] In some embodiments, the electrical connection portion 23, the first flexible circuit board, and the second flexible circuit board are respectively part of an integral flexible circuit board. In this way, the connection reliability between the electrical connection portion 23, the first flexible circuit board, and the second flexible circuit board is relatively good, and during the folding and unfolding process of the screen 100, the electrical connection portion 23 is not easily disconnected from the first flexible circuit board or the second flexible circuit board.

[0139] It can be understood that several screens 100 are specifically introduced in combination with the accompanying drawings. The screen 100 includes a display screen 10 and a support member 20. The display screen 10 includes a first portion 13, a second portion 14, and a third portion 15 that are sequentially connected, and the second portion 14 can be deformed.
