[0043] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0044] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0045] like Figure 1 As shown, Figure 1It is a structural diagram of an electronic device in the prior art. Taking the electronic device as a folding screen mobile phone product as an example, the prior art generally detects different angles of the folding screen by integrating at least two sensors 10' in the electronic device 000'. The electronic device 000' is bent through the bending area 00'. The folding angles are different, the relative positions of the two sensors 10' are different, and the sensing signals obtained by the communication between the two sensors 10' are different, thereby detecting and identifying different folding angles. However, this design structure has the following multiple disadvantages. First, the sensor 10' needs to be integrated into the screen end of the electronic device 000', occupying the layout space of the screen display or other screen components. Second, it increases the use cost of the sensor device. Third, the control of the sensor device requires changing the control circuit, which will affect the layout of the control circuit of the electronic device itself. Fourth, if there is an interference source such as metal or other conductive objects in the communication between sensors, the detection and recognition accuracy will be affected.

[0046] Based on the above problems, the present application proposes an electronic device capable of detecting a bending angle and a detection method thereof, which can improve the detection accuracy of the bending angle and greatly reduce the cost. Specific embodiments of the electronic device capable of detecting a bending angle and a detection method thereof proposed in the present application are described in detail as follows.

[0047] Please refer to Figure 2 and Figure 3 , Figure 2 is a schematic diagram of a planar structure of an electronic device capable of detecting a bending angle provided by an embodiment of the present invention, Figure 3 yes Figure 2 A schematic diagram of an electrical connection structure of a near field communication module, a time-sharing control module and a near field communication processing module, an electronic device 000 capable of detecting a bending angle provided in this embodiment, such as Figure 2 As shown, it can be an electronic device with a bending function, such as a flexible folding screen mobile phone. The drawings of this embodiment are only for illustrative purposes. When it is implemented specifically, it can also be other electronic products, which is not limited in this embodiment. The electronic device 000 of this embodiment includes at least one bending area 00, and the electronic device 000 is bent in the bending area 00 to achieve the bending or folding of the electronic device 000; or optionally, the electronic device 000 includes at least one bending axis (not shown in the drawings), and the electronic device 000 is bent or folded based on the bending axis. The structure of the bendable electronic device 000 is not described in detail in this embodiment, and it can be understood by referring to the setting structure in the relevant technology.

[0048] The electronic device 000 of this embodiment includes a near field communication module 10, a time-sharing control module 20 and a near field communication processing module 30, and the time-sharing control module 20 and the near field communication processing module 30 are both electrically connected to the near field communication module 10;

[0049] The time-sharing control module 20 is used to control the near field communication module 10 to detect the bending angle of the electronic device 000 in the first mode; the time-sharing control module 20 is used to control the near field communication module 10 to perform wireless communication in the second mode;

[0050] The near field communication processing module 30 is used to store a preset table, which includes a comparison table of the bending angle Δα and the magnetic field strength value ΔB. The near field communication processing module 30 is also used to compare and obtain the bending angle detected by the near field communication module 10 in the first mode according to the preset table, and output the result to the electronic device 000;

[0051] At least a portion of the near field communication module 10 is located in the bending area 00 .

[0052] Specifically, the electronic device 000 provided in this embodiment includes a near field communication module 10, a time-sharing control module 20 and a near field communication processing module 30, wherein the near field communication module 10 can be a structure included in the electronic device itself, such as an NFC structure included in a mobile phone or other communication device. The application of NFC (Near Field Communication) technology in mobile terminals has become more and more common, and generally folding screen mobile phones are equipped with NFC communication technology as standard. Therefore, when the electronic device 000 of this embodiment realizes bending angle detection, the near field communication module 10 included in the electronic device 000 itself is reused, which is conducive to saving production costs.

[0053] The working mode of the electronic device 000 may include a first mode and a second mode. In the first mode, the time-sharing control module 20 controls the near field communication module 10 to detect the bending angle of the electronic device 000, that is, the function of the near field communication module 10 is to detect the bending angle of the electronic device 000. In the second mode, the time-sharing control module 20 controls the near field communication module 10 to perform wireless communication, that is, the function of the near field communication module 10 is to realize normal wireless communication of the electronic device.

[0054] The near field communication processing module 30 is used to store a preset table, which may be pre-formulated and stored in the near field communication processing module 30, and the preset table includes a comparison table of the bending angle Δα and the magnetic field strength value ΔB. It is understandable that the present embodiment does not elaborate on the process of pre-formulating the preset table, and the corresponding relationship between the bending angle Δα and the magnetic field strength value ΔB may be constructed through multiple experiments.

[0055] The near field communication processing module 30 is also used to compare the magnetic field strength value detected by the near field communication module 10 with the corresponding relationship of the bending angle in the preset table according to the preset table, thereby obtaining the bending angle of the near field communication module 10 in the first mode corresponding to the magnetic field strength value, and output the result to the electronic device 000, such as outputting it to the system chip of the electronic device 000. The near field communication processing module 30 in this embodiment is equivalent to playing the role of a processor, which is used for data storage, processing and output.

[0056] Since the NFC function in NFC communication technology is mainly implemented by the NFC controller chip, it can be understood that the near field communication module 10 of this embodiment includes an NFC controller chip, and the NFC controller chip (NFC Controller, NFCC) is used to implement the functions of RF front-end devices such as NFC IC chip, differential matching circuit, NFC antenna, etc. The time-sharing control module 20 and the near field communication processing module 30 of this embodiment are both electrically connected to the near field communication module 10, so the time-sharing control module 20 and the near field communication processing module 30 can be integrated into the NFC controller chip (it can be understood that Figure 2 The time-sharing control module 20 and the near field communication processing module 30 are not shown in FIG. Figure 3 Understanding the electrical connection relationship between the three is helpful to reduce the layout cost of the circuit board.

[0057] In this embodiment, at least part of the near field communication module 10 is disposed in the bending area 00 of the electronic device 000. The commonly used theory of near field communication radiation is the Biot-Savant law. This law describes that the magnitude of the magnetic field strength dB generated by the current element Idl at a point P in space is proportional to the magnitude of the current element Idl, proportional to the sine of the angle between the position vector of the current element Idl and the point P and the current element Idl, and inversely proportional to the square of the distance from the current element Idl to the point P; the magnetic field strength can be expressed as follows: Among them, μ0 is the vacuum permeability, and its value is 4π×10 -7 N˙A -2 , I is the source current, and dl is the tiny linear element of the source current. It can be seen that when the NFC antenna in the near field communication module 10 is deformed, the electrical length will change; secondly, the circuit resonance changes, the current I will also change, and then the magnetic field strength will definitely change.

[0058] Therefore, in this embodiment, at least part of the near field communication module 10 is disposed in the bending area 00 of the electronic device 000. The bending angles are different, and the NFC antenna in the near field communication module 10 undergoes different deformation degrees, and the magnetic field strength values ​​will also be different.

[0059] like Figure 4 As shown, Figure 4 It is a schematic diagram of different bending angles of an electronic device provided by an embodiment of the present invention, and an electronic device 000 is taken as an example with eight bending angles, such as 30°, 45°, 60°, 75°, 90°, 120°, 135°, 180°, etc. It should be noted that, in specific implementation, the bending angle of the electronic device includes but is not limited to the eight bending angles exemplified above, and may be other bending angles, such as any bending angle between 0-180°, and the bending angle detection accuracy may be within 5°, for example, any bending angle in a range of 0-180° with a step of 5° can be detected by this embodiment, and this embodiment is only an example.

[0060] As shown in Table 1 below, Table 1 is a preset table for example, that is, a comparison table of eight bending angles generally included in the electronic device 000, the bending angle Δα, and the magnetic field strength value ΔB.

[0061] Table 1:

[0062] Magnetic field strength value ΔB Bending angle Δα Display device bending angle ΔB1 Δα1 30° ΔB2 Δα2 45° ΔB3 Δα3 60° ΔB4 Δα4 75° ΔB5 Δα5 90° ΔB6 Δα6 120° ΔB7 Δα7 135° ΔB8 Δα8 180°

[0063] If the corresponding magnetic field strength value detected by the near field communication module 10 is ΔB1, then the corresponding bending angle is found to be Δα1 through the comparison table of the bending angle Δα and the magnetic field strength value ΔB in the preset table, and then the bending angle of the display device 000 is obtained to be 30° at this time;

[0064] If the corresponding magnetic field strength value detected by the near field communication module 10 is ΔB2, then the corresponding bending angle is found to be Δα2 through the comparison table of the bending angle Δα and the magnetic field strength value ΔB in the preset table, and then the bending angle of the display device 000 is obtained to be 45° at this time;

[0065] If the corresponding magnetic field strength value detected by the near field communication module 10 is ΔB3, then the corresponding bending angle is found to be Δα3 through the comparison table of the bending angle Δα and the magnetic field strength value ΔB in the preset table, and then the bending angle of the display device 000 is obtained to be 60° at this time;

[0066] If the corresponding magnetic field strength value detected by the near field communication module 10 is ΔB4, then the corresponding bending angle is found to be Δα4 through the comparison table of the bending angle Δα and the magnetic field strength value ΔB in the preset table, and then the bending angle of the display device 000 is obtained to be 75° at this time;

[0067] If the corresponding magnetic field strength value detected by the near field communication module 10 is ΔB5, then the corresponding bending angle is found to be Δα5 through the comparison table of the bending angle Δα and the magnetic field strength value ΔB in the preset table, and then the bending angle of the display device 000 is obtained to be 90° at this time;

[0068] If the corresponding magnetic field strength value detected by the near field communication module 10 is ΔB6, then the corresponding bending angle is found to be Δα6 through the comparison table of the bending angle Δα and the magnetic field strength value ΔB in the preset table, and then the bending angle of the display device 000 is obtained to be 120° at this time;

[0069] If the corresponding magnetic field strength value detected by the near field communication module 10 is ΔB7, then the corresponding bending angle is found to be Δα7 through the comparison table of the bending angle Δα and the magnetic field strength value ΔB in the preset table, and then the bending angle of the display device 000 is obtained to be 135° at this time;

[0070] If the corresponding magnetic field strength value detected by the near field communication module 10 is ΔB8, then the corresponding bending angle is found to be Δα8 through the comparison table of the bending angle Δα and the magnetic field strength value ΔB in the preset table, and then the bending angle of the display device 000 is obtained to be 180°.

[0071] It can be understood that the present embodiment is only an example in which the near field communication module 10 detects the corresponding magnetic field strength value as ΔB1, and finds the corresponding bending angle as Δα1 through the preset table, and then the bending angle of the display device 000 is 30°. In some other optional embodiments, the bending angle Δα1 may also correspond to the bending angle of the display device 000 of 45° or 60°, etc., which is not limited in the present embodiment.

[0072] Finally, the near-field communication processing module 30 compares the magnetic field strength value and the bending angle detected by the near-field communication module 10 in the first mode according to the above-mentioned preset table, obtains the bending angle of the electronic device 000 at this time, and outputs the result to the electronic device 000. For example, if it is reported to the system chip of the electronic device, it is beneficial to increase the playability of the electronic device, enhance the user experience, and maintain user stickiness.

[0073] The electronic device 000 provided in this embodiment realizes the detection of the bending angle by multiplexing the near field communication module 10 included in it. In the first mode, the time-sharing control module 20 controls the near field communication module 10 to detect the bending angle of the electronic device 000, that is, the function of the near field communication module 10 at this time is to detect the bending angle of the electronic device 000; in the second mode, the time-sharing control module 20 controls the near field communication module 10 to perform wireless communication, that is, the function of the near field communication module 10 at this time is to realize the normal wireless communication of the electronic device 000. At least part of the near field communication module 10 is arranged in the bending area 00 of the electronic device 000. The bending angle of the electronic device 000 is different, and the NFC antenna in the near field communication module 10 has different deformation degrees, and the magnetic field strength value will also be different. The near field communication processing module 30 is used to store a preset table, which can be pre-formed and stored in the near field communication processing module 30. The preset table includes a comparison table of the bending angle Δα and the magnetic field strength value ΔB. After the display device 000 is bent, the near field communication module 10 detects the magnetic field strength value after the bending, and the near field communication processing module 30 compares the magnetic field strength value and the bending angle detected by the near field communication module 10 in the first mode according to the above preset table, and obtains the bending angle of the electronic device 000 at this time. The time-sharing control module 20 and the near field communication processing module 30 can be integrated into the control chip of the electronic device 000, which reduces the layout space of the device structure without affecting the performance of the device and reduces the cost of the whole machine. And because the electronic device 000 itself needs to be provided with the near field communication module 10 to realize the wireless communication function, the design of the present disclosure is only to set it in the bending area 00, and the near field communication processing module 30 compares the magnetic field strength value and the bending angle detected by the near field communication module 10 in the first mode according to the stored preset table, and obtains the bending angle of the electronic device 000 at this time, which can realize accurate detection of different bending angles of the electronic device 00, thereby increasing the playability of the electronic device 000, improving the user experience, and maintaining user stickiness.

[0074] Optionally, the preset table stored in the near field communication processing module 30 of this embodiment can be constructed by constructing a correspondence between the magnetic field strength value and the bending angle, and the magnetic field strength value and the bending angle have a monotonic relationship. According to the Biot-Savart law of the near field communication radiation theory mentioned above, the correspondence between the magnetic field strength value and the bending angle conforms to the monotonic relationship and is monotonically decreasing. When the bending angle is larger, such as the maximum 180°, the magnetic field strength value is the largest, and when the bending angle is smaller, such as 0° or 30°, the magnetic field strength value is the smallest or decreases. Therefore, the accuracy of the measured angle can be improved by detecting the magnetic field strength value to correspondingly search for the bending angle.

[0075] Optional, such as Figure 2As shown, the near field communication module 10 in this embodiment includes a near field communication antenna 101, and the near field communication antenna 101 includes a coil formed by at least one conductive line; at least part of the coil is located in the bending area 00. This embodiment explains the principle that the near field communication module 10 can detect changes in magnetic field strength. The near field communication module 10 includes a near field communication antenna 101, and the near field communication antenna 101 can be a coil structure formed by at least one conductive line, and at least part of the coil in the near field communication antenna 101 is located in the bending area 00. When the electronic device 000 is bent in the bending zone 00, the coil located in the bending zone 00 is deformed, the electrical length will change, and then the circuit resonance will change, the current will also change, and then the magnetic field strength of the near-field communication antenna 101 in the near-field communication module 10 at the bending zone 00 will also change. Therefore, after the electronic device 000 is bent, the near-field communication module 10 can detect the value of the changed magnetic field strength, and the near-field communication processing module 30 compares the corresponding relationship between the magnetic field strength value and the bending angle, and then obtains the bending angle of the electronic device at this time. Not only is the measurement accuracy accurate, but also no other devices such as sensors are required, which is conducive to cost saving.

[0076] In some optional embodiments, please refer to Figure 3 and Figure 5 , Figure 5 It is another planar structural schematic diagram of an electronic device capable of detecting bending angles provided in an embodiment of the present invention. In this embodiment, the number of turns of the coil of the near-field communication antenna 101 is N, where N is a positive integer; in the near-field communication antenna 101, at least one turn of the coil is located outside the bending area 00.

[0077] This embodiment explains that the near field communication module 10 includes a near field communication antenna 101, and the near field communication antenna 101 can be a coil structure formed by at least one conductive wire. In order to detect the bending angle, that is, to meet the requirement that the electronic device 000 drives the near field communication antenna 101 to deform after bending at the bending area 00, at least part of the coil needs to be located in the bending area 00. The number of turns of the coil of the near field communication antenna 101 is N turns. In the near field communication antenna 101 composed of N turns of coils, at least one turn of the coil is arranged outside the bending area 00, which can ensure that in the second mode, when the near field communication module 10 is used to realize the wireless communication function of the electronic device 000, the communication performance requirement of the near field communication antenna 101 is met.

[0078] It can be understood that Figure 5In the near-field communication antenna 101 composed of only N turns of coils, a complete circle of coils is set outside the bending zone 00. In a specific implementation, the coils with partial turns (such as partial turns of the outer circle) can be located in the bending zone 00, and the coils with the remaining partial turns (such as partial turns of the inner circle) can be located outside the bending zone 00, so as to ensure that the near-field communication antenna 101 can detect the magnetic field strength value through deformation in the first mode and can improve the effect of normal wireless communication in the second mode.

[0079] In some optional embodiments, please refer to Figure 3 and Figure 6 , Figure 6 It is another planar structural schematic diagram of an electronic device that can detect bending angles provided in an embodiment of the present invention. In this embodiment, the near-field communication module 10 includes two electrically connected near-field communication antennas 101, and each near-field communication antenna 101 includes a coil formed by at least one conductive wire; at least one near-field communication antenna 101 is located in the bending area 00.

[0080] This embodiment explains that the near field communication module 10 may include two near field communication antennas 101, and each near field communication antenna 101 may be a coil structure formed by at least one conductive wire. In order to realize the detection of the bending angle, that is, in order to satisfy the deformation of the near field communication antenna 101 caused by the electronic device 000 after bending at the bending area 00, at least part of the near field communication antenna 101 needs to be located in the bending area 00. In this embodiment, the near field communication module 10 includes two electrically connected near field communication antennas 101. At least one near field communication antenna 101 is located in the bending area 00. The near field communication antenna 101 located in the bending area 00 can be used for the detection of the bending angle in the first mode. In the second mode, the two near field communication antennas 101 included in the near field communication module 10 are electrically connected, that is, the two electrically connected near field communication antennas 101 can be used together to realize the wireless communication function of the electronic device 000, which is conducive to improving the antenna performance.

[0081] Optionally, when the near field communication module 10 includes two near field communication antennas 101, the two near field communication antennas 101 can be electrically connected in series; or, the two near field communication antennas 101 can be electrically connected in parallel. By connecting the two near field communication antennas 101 included in the near field communication module 10 in series or in parallel, the two near field communication antennas 101 can be controlled by a set of control circuits, which can save costs.

[0082] It should be noted that, in this embodiment, when the near-field communication module 10 includes two near-field communication antennas 101, the series and parallel structures of the two near-field communication antennas 101 are not described in detail. The two near-field communication antennas 101 may be the same or different, and this embodiment does not make any limitation. It is only necessary that at least one of the two near-field communication antennas 101 is located in the bending zone 00, so that the effect of bending angle detection can be achieved by multiplexing the near-field communication antenna 101 in this embodiment.

[0083] In some optional embodiments, please refer to Figure 2 and Figure 7 , Figure 7 yes Figure 2 Another electrical connection structure diagram of the near field communication module, the time-sharing control module and the near field communication processing module. In this embodiment, the near field communication processing module 30 also includes a conversion module 301, and the conversion module 301 is used to convert the magnetic field strength value detected by the near field communication module 10 into an analog quantity; wherein the analog quantity includes any one of a voltage value, a current value, a phase value, and a frequency value;

[0084] The preset table stored in the near field communication processing module 30 includes a comparison table of bending angles and analog quantities.

[0085] This embodiment explains that the near field communication processing module 30 also includes a conversion module 301, and the conversion module 301 is used to convert the magnetic field strength value detected by the near field communication module 10 into an analog quantity. Since in NFC communication technology, the NFC function is mainly realized by the NFC controller chip, that is, it can be understood that the near field communication module 10 of this embodiment includes an NFC controller chip, and the NFC controller chip is used to realize the functions of the RF front end such as the NFC IC chip, differential matching circuit, NFC antenna and other devices. The time-sharing control module 20 and the near field communication processing module 30 of this embodiment are both electrically connected to the near field communication module 10, so the time-sharing control module 20 and the near field communication processing module 30 can be integrated in the NFC controller chip, and the NFC IC chip can detect the changes in electrical signals such as voltage, current, phase, and frequency on the NFC control circuit. Therefore, the near field communication processing module 30 is also provided with a conversion module 301, that is, when the near field communication processing module 30 is integrated into the NFC controller chip, the function inherent in the NFC controller chip itself can realize the conversion of the magnetic field strength value into an analog quantity, wherein the analog quantity can be any one of the voltage value, current value, phase value, and frequency value commonly used in the integrated circuit. The conversion module 301 converts the magnetic field strength value detected by the near field communication module 10 into an analog quantity, which is equivalent to being understood as the magnetic field changing into an electric field. There are only electrical signals in the circuit, while there are magnetic signals in space. Due to its characteristics, the magnetic field is not easy to measure in practical applications, and it is difficult to define a value. Therefore, after the conversion module 301 in this embodiment converts the analog quantity into the analog quantity in the circuit, the internal integrated circuit of the near field communication processing module 30 can measure itself, and then the analog quantity can more intuitively reflect the change of the magnetic field strength value, making the detection result more intuitive.

[0093] If the corresponding magnetic field strength value detected by the near field communication module 10 is ΔB4, the analog value corresponding to the magnetic field strength value ΔB4 obtained by the conversion module 301 after conversion is ΔH4, then the corresponding bending angle is found to be Δα4 through the comparison table of the bending angle Δα and the magnetic field strength value ΔH in the preset table, and then the bending angle of the display device 000 at this time is obtained to be 75°;

[0094] If the corresponding magnetic field strength value detected by the near field communication module 10 is ΔB5, the analog value corresponding to the magnetic field strength value ΔB5 obtained by the conversion module 301 after conversion is ΔH5, then the corresponding bending angle is found to be Δα5 through the comparison table of the bending angle Δα and the magnetic field strength value ΔH in the preset table, and then the bending angle of the display device 000 is obtained to be 90° at this time;

[0095] If the corresponding magnetic field strength value detected by the near field communication module 10 is ΔB6, the analog value corresponding to the magnetic field strength value ΔB6 obtained by the conversion module 301 after conversion is ΔH6, then the corresponding bending angle is found to be Δα6 through the comparison table of the bending angle Δα and the magnetic field strength value ΔH in the preset table, and then the bending angle of the display device 000 at this time is obtained to be 120°;

[0096] If the corresponding magnetic field strength value detected by the near field communication module 10 is ΔB7, the analog value corresponding to the magnetic field strength value ΔB7 obtained by the conversion module 301 after conversion is ΔH7, then the corresponding bending angle is found to be Δα7 through the comparison table of the bending angle Δα and the magnetic field strength value ΔH in the preset table, and then the bending angle of the display device 000 at this time is obtained to be 135°;

[0097] If the corresponding magnetic field strength value is ΔB8 detected by the near field communication module 10, the analog quantity corresponding to the magnetic field strength value ΔB8 obtained after conversion by the conversion module 301 is ΔH8, then the corresponding bending angle is found to be Δα8 through the comparison table of the bending angle Δα and the magnetic field strength value ΔH in the preset table, and then the bending angle of the display device 000 is obtained to be 180° at this time.

[0098] Finally, the near-field communication processing module 30 outputs the result to the electronic device 000, such as reporting it to the system chip of the electronic device, so as to accurately detect the different bending angles of the electronic device 000, thereby improving the user experience. At the same time, the change in the magnetic field strength value can be more intuitively reflected through analog quantity, making the detection result more intuitive.

In this embodiment, the near field communication module 10 may include two near field communication antennas 101. The two near field communication antennas 101 may be respectively arranged on both sides of the bending area 00, and the relative position of the other near field communication antenna 101 is detected by one of the near field communication antennas 101. Assuming that the near field communication antenna 101A is in a stationary state, the display device 000 is bent, which will cause the distance of the near field communication antenna 101B relative to the near field communication antenna 101A to change. For the near field communication antenna 101A, the load will change, thereby affecting the change of the analog quantity in the NFC controller chip of the near field communication module 10, and realizing the function of detecting different bending angles.

[0100] It is understandable that the two near field communication antennas 101 of this embodiment can be integrated into an electronic device (such as Figure 8 As shown), the two near field communication antennas 101 may also be arranged in a metal middle frame of the electronic device (as shown Fig. 9 As shown), the bending angle can be detected.

The time-sharing control module 20 and the near field communication processing module 30 can be integrated into the control chip of the electronic device, which reduces the layout space of the device structure without affecting the performance of the device, and reduces the cost of the whole machine. And because the electronic device itself needs to be provided with a near field communication module 10 to realize the wireless communication function, the design of this embodiment is only to set it in the bending area 00, the bending angle of the electronic device 000 is different, and the NFC antenna in the near field communication module 10 has different deformation degrees, and the magnetic field strength value will also be different. Therefore, the near field communication processing module 30 compares the magnetic field strength value and the bending angle detected by the near field communication module 10 in the first mode according to the stored preset table, and the bending angle of the electronic device 000 at this time can be obtained, which can realize accurate detection of different bending angles of the electronic device 000, thereby increasing the playability of the electronic device, improving the user experience, and maintaining user stickiness.
