[0008] The main objective of the embodiments of the present application is to propose a flexible screen terminal, an antenna adjustment method and a storage medium, aiming at least to ensure that the flexible screen terminal antenna is in an optimal working state, improve the working efficiency of the antenna, thereby improving the communication performance of the flexible screen terminal, and better meeting the business needs of users.

[0009] In order to clarify the purpose, technical solution and advantages of the embodiments of the present application, the following describes each embodiment of the present application in detail with the aid of drawings. However, those skilled in the art can understand that many technical details are proposed in each embodiment of the present application to better understand the present application. However, the technical solution claimed in the present application can be realized without these technical details and various changes and modifications based on the following embodiments. The division of the following embodiments is for the convenience of explanation and should not be construed as any limitation on the specific implementation form of the present application, and each embodiment can be cited in combination with each other on the premise that there is no contradiction.

[0010] An embodiment of the present application relates to a flexible screen terminal, and in a specific implementation, the flexible screen terminal of the embodiment of the present application can be a folding screen mobile phone, a folding screen computer, a hinge screen mobile phone, and various flexible screen wearable devices. The structural conceptual diagram of the flexible screen terminal of this embodiment can be as shown in FIG. 1, and the flexible screen terminal 10 of this embodiment can include, but is not limited to, the following modules and components: a first detection module 11, a control module 12, a second detection module 13, an adjustment module 14, and an antenna 15. Here, the control module 12 is respectively connected to the first detection module 11, the second detection module 13, and the adjustment module 14, and the adjustment module 14 is connected to the antenna 15.

[0011] In one example, the flexible screen terminal of this embodiment may be a folding screen mobile phone, and the first detection module 11, the control module 12, the second detection module 13, the adjustment module 14 and the antenna 15 may be arranged under the screen of the folding screen mobile phone, or may be arranged on the motherboard of the folding screen mobile phone, and the control module 12 is respectively connected to the first detection module 11, the second detection module 13 and the adjustment module 14, and the adjustment module 14 is also connected to the antenna 15. Here, the first detection module 11, the control module 12, the second detection module 13 and the adjustment module 14 may be integrated into an antenna adjustment device, or may be separately installed in the flexible screen mobile phone. Figure 2 is a structural conceptual diagram of a folding screen mobile phone.

[0012] The first detection module 11 is used for detecting and collecting communication performance parameters of the terminal, and sending the parameters to the control module 12 .

[0013] Specifically, the first detection module 11 can continue to detect and collect the communication performance parameters of the terminal, and send these communication performance parameters to the control module 12 after collecting the communication performance parameters of the terminal.

[0014] In a specific implementation, the first detection module can be realized based on a transceiver inside the terminal, including but not limited to a transceiver, a communication radio frequency master chip and several amplifiers.

[0015] In one example, the first detection module 11 can collect the communication performance parameters of the terminal once every predetermined time, and the intermittent collection method can effectively save power resources.

[0016] In one example, the first detection module 11 can collect the communication performance parameters of the terminal once, that is, after the folding state of the terminal changes.

[0017] In one example, the communication performance parameters acquired by the first detection module 11 include the overall communication performance parameters of the terminal, which include any combination of the terminal's emission power, reference signal receiving power value (abbreviated as RSPR), received signal strength indication value (abbreviated as RSSI), signal noise ratio (abbreviated as SNR), multiple-in multiple out rank (abbreviated as MIMO Rank), modulation and coding scheme (abbreviated as MCS), modulation rank, modulation coefficient, throughput rate, error rate, etc.

[0018] In another example, the communication performance parameters acquired by the first detection module 11 further include communication performance parameters of each antenna of the terminal, and the communication performance parameters of each antenna of the terminal include any combination of the emission power of each antenna, the reference signal received power value RSPR of each antenna, the received signal strength indication value RSSI of each antenna, the channel detection reference signal value (Sounding Reference Signal, abbreviated as SRS) of each antenna path, etc.

[0019] When the control module 12 determines that the received parameters do not meet the predetermined business requirements, it controls the second detection module 13 to detect and collect the folding angle of the terminal.

[0020] In a specific implementation, the control module 12 obtains the communication performance parameters sent by the first detection module 11, and then judges whether the communication performance of the terminal meets the predetermined business requirements based on the communication performance parameters. If the communication performance of the terminal does not meet the predetermined business requirements, the control module 12 transmits a folding angle detection command to the second detection module 13 at any time, and controls the second detection module 13 to detect and collect the folding angle of the terminal. This allows the terminal to quickly respond when communication performance deteriorates, and protects the business from interruption. Here, the predetermined business requirements can be set by those skilled in the art according to actual needs, and the embodiment of the present application is not specifically limited thereto.

[0021] In one example, if the communication performance of the terminal can meet the requirements of the current business, the flexible screen terminal does not adjust the antenna, maintains the normal operation of the first detection module 11, and continuously or periodically detects and collects the communication performance parameters of the terminal.

[0022] The second detection module 13 is used for detecting and collecting the folding angle of the terminal, and transmitting the folding angle of the terminal to the control module 1212 .

[0023] Specifically, after the control module 12 determines that the communication performance of the terminal does not meet the specified business requirements, it sends a folding angle detection command to the second detection module 13, and after receiving the command, the second detection module 13 can detect and collect the folding angle of the terminal and send the folding angle to the control module 12.

[0024] In a specific implementation, the second detection module 13 can also detect and collect the folding state of the terminal, which can include a folded state, a fully closed state, and a fully unfolded state.

[0025] In one example, the second detection module 13 may include an infrared sensor, and after receiving a command, the second detection module 13 uses the infrared sensor to emit infrared rays to detect and collect the folding angle of the flexible screen terminal.

[0026] In one example, the second detection module 13 obtains information of a baseband display page, and detects and collects the folding angle of the flexible screen terminal according to the information of the baseband display page.

[0027] In another example, the concept diagram of the second detection module 13 detecting and collecting the folding angle of the terminal is as shown in FIG. 3, the flexible screen terminal further includes a first screen and a second screen, the first screen and the second screen may be two regions of a complete screen, and the first screen and the second screen are divided for ease of explanation. The second detection module 13 emits a charge signal to the outside through the first screen of the terminal, and when the emitted charge signal encounters the second screen, some charges will be reflected back, and the second detection module 13 can determine the number of charges reflected by the second screen to the first screen, and based on the number of charges of the first screen reflected by the second screen, recombine the correspondence between the number of predetermined charges and the folding angle to obtain the folding angle of the terminal. However, the correspondence between the number of predetermined charges and the folding angle can be set by a person skilled in the art based on a large amount of experiments. The method of emitting and reflecting charges allows the folding angle of the terminal to be accurately detected and collected without using an additional sensor.

[0028] Specifically, the flexible screen terminal of this embodiment further includes a descending electromagnetic wave absorption ratio chip (abbreviated as descending SAR chip), and the second detection module 13 is connected to the descending SAR chip, which is further connected to each antenna of the first screen and each antenna of the second screen respectively. When the second detection module 13 detects and collects the folding angle of the terminal, it can continue to emit charge signals to the outside through the charge bar circuit of the descending SAR chip through each antenna of the first screen, and when the emitted charge signal encounters each antenna of the second screen, some charges are reflected and returned, and the second detection module 13 collects the charges reflected and returned by each antenna of the second screen through the induction circuit of the descending SAR chip and stores them in a register, and after analog-to-digital conversion, each antenna of the second screen determines the number of charges reflected by each antenna of the first screen, and the second detection module 13 obtains the folding angle of the terminal based on the number of charges of each antenna reflected by the first screen by combining the correspondence between the predetermined number of charges and the folding angle. The accuracy of the obtained folding angle can be further improved by simultaneously emitting charges from multiple antennas and performing simultaneous multi-channel multiple detection.

[0029] In one example, the drop SAR chip may be connected to other metal coupling units on the terminal screen, and the second detection module 13 continues to emit charge signals to the outside through these metal coupling units via the charge rod circuit of the drop SAR chip.

[0030] In one embodiment, the number of charges reflected back may be expressed as a SAR value, which is inversely proportional to the distance and the folding angle, and proportional to the induced projection area. The correspondence between a given number of charges and the folding angle may be as shown in Table 1.

[0031] [Table 1]

[0032] For example, if the second detection module 13 determines that the number of charges reflected by the second screen to the first screen is 1.0 W / kg, it further combines the correspondence between the predetermined number of charges and the folding angle based on the number of charges reflected by the second screen to the first screen, and determines that the folding angle of the terminal at that time is 120°.

[0033] The control module 12 is further used for determining a target working state of the antenna based on the folding angle, by combining the folding angle and the corresponding relationship between the predetermined folding angle and the optimal working state of the antenna of the terminal.

[0034] Specifically, after receiving the folding angle of the terminal transmitted from the second detection module 13, the control module 12 can determine the target working state of the antenna based on the folding angle by combining the corresponding relationship between a predetermined folding angle and the optimal working state of the antenna of the terminal. Considering that the positions of the antennas of the flexible screen terminal are all fixed, the arrangement of the communication performance of the antenna of the flexible screen terminal is only arranged based on the fully opened or fully closed state of the flexible screen terminal, so that the orthogonal characteristic of the antenna of the flexible screen terminal is deteriorated during the folding process, and the working efficiency of the antenna is also reduced, and the antenna target working state is determined based on the folding angle, that is, the optimal working state of the antenna at the folding angle can improve the working efficiency of the antenna of the flexible screen terminal, thereby improving the communication performance of the flexible screen terminal and better meeting the business requirements of users.

[0035] In a specific implementation, the flexible screen terminal further includes a memory, and the correspondence between a predetermined folding angle and the optimal working state of the antenna of the terminal can be obtained based on a large amount of simulation experiments and pre-stored in the memory of the flexible screen terminal in the form of an algorithm. After receiving the folding angle of the terminal, the control module 12 can call the pre-stored algorithm to determine the target working state of the antenna.

[0036] The adjustment module 14 is used to adjust the operating conditions of the antenna 15 to target operating conditions.

[0037] In a specific implementation, the adjustment module 14 is connected to N antennas of the terminal, where N is an integer greater than 0. The antenna operating state may be the number of operating antennas and / or a combination of operating antennas. The control module 12 is further used for determining M target antennas among the N antennas based on the folding angle by combining the corresponding relationship between the predetermined folding angle and the target antenna, where M is an integer greater than 0 and less than N. The adjustment module 14 is used for turning on the M target antennas and turning off antennas other than the M target antennas. Considering that the antenna arrangement of the relevant 5G flexible screen terminal is fixed and single, the relevant antenna combination is arranged on the basis of the fully unfolded state and / or the fully closed state of the flexible screen terminal. When the folding angle of the terminal is any angle, the isolation and orthogonal characteristics of the conventional antenna combination cannot meet the business needs. The flexible screen terminal of this embodiment invokes different antenna combinations at different folding angles, thereby ensuring that the isolation between each antenna in the antenna combination is optimal, the orthogonal performance is best, and the total gain of the antennas is strongest, which further improves the operating efficiency of the antennas of the flexible screen terminal and further improves the communication performance of the flexible screen terminal.

[0038] In one example, the adjustment module 14 can be realized based on an array switch for each antenna.

[0039] In one example, the correspondence between the predetermined folding angles and the target antennas can be obtained based on a large amount of simulation experiments and pre-stored in the memory of the flexible screen terminal in the form of an algorithm. After receiving the folding angles of the terminal, the control module 12 can call the pre-stored algorithm to determine the M target antennas from the N antennas.

[0040] For example, seven antennas are arranged on the terminal, and the arrangement positions of the seven antennas may be as shown in Figure 4, where antenna 1, antenna 2, antenna 3, and antenna 4 are conventional 4x4 MIMO antennas, antenna 5 and antenna 6 are newly added auxiliary antennas that can operate in the 5G frequency band, and antenna 7 is an LTE antenna that can operate in the 5G frequency band after modification. The correspondence relationship between the predetermined folding angle and the target antenna may be as shown in Table 2.

[0041] [Table 2]

[0042] When the folding angle of the terminal acquired by the second detection module 13 is 150°, the control module 12 combines the correspondence between the predetermined folding angle and the target antenna based on the folding angle of the terminal, and determines the target antennas to be antenna 1, antenna 2, antenna 4, and antenna 5. The adjustment module 14 turns on antenna 1, antenna 2, antenna 4, and antenna 5, and turns off antenna 3, antenna 6, and antenna 7.

[0043] In one example, after the adjustment module 14 adjusts the operating state of the antenna to the target operating state, the first detection module 11 can continue to detect and acquire the communication performance parameters of the terminal and send the parameters to the control module 12, and the control module 12 continues to determine whether the communication performance of the terminal meets the current business demands, and if not, continues to adjust the operating state of the antenna until the communication performance of the terminal meets the current business demands.

[0044] The flexible screen terminal of this embodiment includes a first detection module, a second detection module, a control module, an adjustment module, and an antenna, the first detection module is used for detecting and collecting communication performance parameters of the terminal and sending the parameters to the control module, the control module is used for controlling the second detection module to detect and collect the folding angle of the terminal when the received parameters do not meet the predetermined business requirements, so as to monitor the communication performance of the terminal in real time, and can quickly respond when the terminal communication performance deteriorates to prevent business interruption. The second detection module is further used for sending the folding angle to the control module, the control module is further used for combining the correspondence between the predetermined folding angle and the optimal operating state of the antenna based on the folding angle to determine the target operating state of the antenna, and the adjustment module is used for adjusting the operating state of the antenna to the target operating state. When the communication performance of the terminal does not meet the specified business requirements, the flexible screen terminal of the present application can determine the current folding angle and adjust the operating state of the antenna to the operating state corresponding to the folding angle, i.e., the optimal operating state, so as to improve the operating efficiency of the antenna of the flexible screen terminal, thereby improving the OTA performance of the flexible screen terminal, increasing the business data throughput of the terminal, and better meeting the user's business needs.

[0045] Furthermore, in order to highlight the innovative aspects of the present application, this embodiment does not introduce modules that are not closely related to solving the technical problem proposed in the present application, but this does not indicate that there are no other modules in this embodiment.

[0046] Another embodiment of the present application relates to a flexible screen terminal, and the structural conceptual diagram of the flexible screen terminal of this embodiment may be as shown in FIG. 5, and the flexible screen terminal 10 of this embodiment includes a first detection module 11, a control module 12, a second detection module 13, an adjustment module 14, a first screen antenna 251, a second screen antenna 252, and a stretched contact module 26. Here, the control module 12 is connected to the first detection module 11, the second detection module 13, and the adjustment module 14 respectively, and the adjustment module 14 is also connected to the first screen antenna 251, the second screen antenna 252, and the stretched contact module 26 respectively, and the stretched contact module 26 is also connected to the first screen antenna 251 and the second screen antenna 252 respectively. Here, the stretched contact module 26 includes P stretched contacts for communicating the first screen antenna 251 and the second screen antenna 252, where P is an integer greater than 0.

[0047] The control module 12 is further used for determining Q target extension contacts among the P extension contacts based on the folding angle by combining the corresponding relationship between the predetermined folding angle and the target extension contacts, where Q is an integer greater than 0 and less than P.

[0048] The adjustment module 14 is further used to turn on the Q target extension contacts to communicate with the antenna 251 of the first screen and the antenna 252 of the second screen.

[0049] In a specific implementation, the P extension contacts of the extension contact module 26 are respectively connected to the antenna 251 of the first screen and the antenna 252 of the second screen, and the control module 12 receives the folding angle of the terminal transmitted from the second detection module 13, and then, based on the folding angle, combines the corresponding relationship between the predetermined folding angle and the target extension contact to determine Q target extension contacts among the P extension contacts, and the adjustment module 14 turns on the Q target extension contacts to communicate with the antenna of the first screen and the antenna of the second screen. Due to the need for folding in the folding screen terminal, there are metal devices such as metal hinges, suction magnets, metal piece decorations and the like between the first screen and the second screen, and the two screens are relatively independent, so the net spatial area of ​​the antenna is not a completely continuous radiator, the net spatial area of ​​the antenna is small, and the effective length of the antenna is short. The flexible screen terminal of this embodiment includes P extended contacts, and Q extended contacts are turned on according to the folding angle, so as to connect the antenna 251 of the first screen and the antenna 252 of the second screen, thereby making the net spatial area of ​​the terminal antenna a completely continuous radiator, increasing the effective length of the additional antenna, and expanding the net spatial area of ​​the terminal antenna.

[0050] In one example, the regulation module 14 can be realized based on several single-ended double-throw switches that control each of the stretch contacts in the stretch contact module.

[0051] In one example, the correspondence between the predetermined folding angle and the target stretching contacts may be obtained based on a large amount of simulation experiments and pre-stored in the memory of the flexible screen terminal in the form of an algorithm. After receiving the folding angle of the terminal, the control module 12 can call the pre-stored algorithm to determine the Q target stretching contacts from the P stretching contacts.

[0052] In one example, the stretch contact module 26 includes a total of six stretch contacts, including stretch contact 1, stretch contact 2, stretch contact 3, stretch contact 4, stretch contact 5, and stretch contact 6, and the position arrangement of the six stretch contacts may be as shown in FIG. 7. When the control module 12 determines that stretch contact 3 and stretch contact 4 are the target stretch contacts, the adjustment module 14 turns on stretch contact 3 and stretch contact 4 to communicate with the antenna of the first screen and the antenna of the second screen.

[0053] In one example, the conceptual diagram of the antennas after being connected at the extended contacts may be as shown in FIG. 7, where antenna 251 on the first screen is connected to antenna 252 on the second screen, and the net spatial area of ​​the antennas forms a perfect continuous radiator.

[0054] In this embodiment, the terminal includes a first screen and a second screen, and further includes an extension contact module used to connect the antenna of the first screen and the antenna of the second screen, and having P extension contacts, which is an integer greater than 0; the control module is further used to combine a corresponding relationship between a predetermined folding angle and a target extension contact based on the folding angle to determine Q target extension contacts, which is an integer greater than 0 and less than P, for the P extension contacts; and the adjustment module is further used to turn on the Q target extension contacts and connect the antenna of the first screen and the antenna of the second screen. Considering that the two screens of the flexible screen terminal are relatively independent, the net spatial area of ​​the antenna is not a complete continuous radiator, the net spatial area of ​​the antenna is small, and the effective length of the antenna is short, the flexible screen terminal of this embodiment further includes P extension contacts, and turns on Q target extension contacts based on the folding angle, so as to connect the antenna of the first screen and the antenna of the second screen, thereby making the net spatial area of ​​the terminal antenna a complete continuous radiator, increasing the effective length of the antenna, and expanding the net spatial area of ​​the terminal antenna.

[0055] Furthermore, in order to highlight the innovative aspects of the present application, this embodiment does not introduce modules that are not closely related to solving the technical problem proposed in the present application, but this does not indicate that there are no other modules in this embodiment.

Here, the control module 12 is respectively connected to the first detection module 11, the second detection module 13, and the adjustment module 14, and the adjustment module 14 is also connected to the antenna 15.

[0057] The conceptual diagram of the placement position of the flexible antenna 37 in this embodiment may be as shown in FIG. 9, where the flexible antenna 37 is respectively connected to the first screen of the terminal and the second screen of the terminal, and the first screen and the second screen are rotatably connected via a connection device.

[0058] The control module 12 is used for determining an optimal resonant frequency point of the flexible antenna 37, and combining the corresponding relationship between the predetermined optimal resonant frequency point and the folding angle, to determine a target folding angle corresponding to when the flexible antenna 37 operates at the optimal resonant frequency point. The adjustment module 14 is further used for driving the connection device between the first screen and the second screen, and rotating the terminal to the target folding angle.

[0059] Specifically, the control module 12 is used to determine an optimal resonant frequency point of the flexible antenna 37 according to the current operating frequency band of the terminal, and to determine a target folding angle corresponding to the flexible antenna 37 operating at the optimal resonant frequency point by combining the corresponding relationship between the predetermined optimal resonant frequency point and the folding angle. The adjustment module 14 drives the connection device between the first screen and the second screen according to the target folding angle, and rotates the terminal to the target folding angle, thereby increasing the electrical length of the flexible antenna 37, and making the flexible antenna 37 operate at the optimal resonant frequency point, so as to further improve the communication performance of the flexible screen terminal.

[0060] In one example, the tuning module 14 can be realized based on an antenna tuning chip.

[0061] In one example, the connecting device may be a drive motor.

[0062] In one example, the correspondence between the predetermined optimal resonant frequency point and the folding angle can be obtained based on a large amount of simulation experiments and pre-stored in the memory of the flexible screen terminal in the form of an algorithm. After receiving the folding angle of the terminal, the control module 12 can call the pre-stored algorithm to determine the corresponding target folding angle when the flexible antenna 37 operates at the optimal resonant frequency point.

[0063] In one example, the adjustment module 14 can also display the target adjustment angle on the first screen and / or the second screen of the terminal, and instruct the corresponding user of the terminal to rotate the terminal to the target folding angle. This embodiment allows the user to manually adjust the folding angle of the terminal, which can improve the interactivity between the user and the terminal.
