However, when the above method solves the problem of radio frequency sensitivity attenuation, the thickness of the mobile terminal may be increased, the structural stability may be reduced, and the yield of the module may be reduced due to long FPC wiring, Cof (Chip on Film) process limitation, and the like.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a flowchart illustrating a method of setting MIPI frequencies, which may be used in a terminal device, such as a mobile phone, a tablet computer, etc., as shown in fig. 1, according to an exemplary embodiment, and which may include the following steps.

In step S11, the currently set MIPI frequency is acquired as the current frequency.

The MIPI frequency may be used to represent a clock frequency of the MIPI. Fig. 2 is a schematic diagram of a MIPI communication scenario in accordance with an example embodiment. The processor can be a CPU, and the MIPI of the processor side is connected with the DSI of the screen side. MIPI is synchronized with the DSI's clock. The processor may send display data to the DSI at the clock frequency. In one possible implementation, there may be one or more data lanes between the MIPI and the DSI, each data lane may support high-speed unidirectional communication, and each data lane may transmit display data to the DSI according to a clock frequency. The terminal equipment can acquire the currently set MIPI frequency by acquiring the clock frequency of the current MIPI.

In a high-speed mode, the maximum frequency of the MIPI can reach more than 1.2GHz, and factors such as the process and stability of a screen (such as an LCD, an LED, and the like) limit the clock frequency of the MIPI, for example, the MIPI frequency is limited between 600MHz and 1 GHz. Therefore, the clock frequency of the MIPI overlaps with the frequency band of the radio frequency signal used for mobile communication. Thus, when the MIPI on the processor side transmits display data to the DSI on the screen side, the radio frequency signal of the terminal device may be affected. In the related technology, the influence of MIPI communication on radio frequency signals is reduced by adopting modes of wrapping a silver film with an FPC (flexible printed circuit) and grounding, and the like, and the problems of increased thickness of terminal equipment, reduced structural stability, reduced module yield and the like exist.

In step S12, network information for identifying the network with which the terminal device is registered is acquired.

The network information may be used to identify a network in which the terminal device is registered, such as a 3G network or a 4G network in which the terminal device is registered, a network in which area the terminal device is registered, a network in which system the terminal device is registered (for example, a CDMA (Code Division Multiple Access) network, a GSM (global system for Mobile communication) network), and the like. The present disclosure does not limit the network division method, the network category, and the like. In a possible implementation manner, the network information may be a name of a network, a number of the network, a network system, a network operator, and the like, and the disclosure is not limited thereto.

The network in which the terminal device is registered may comprise one or more frequency bands. In order to reasonably use frequency bands and prevent various communications in various regions from interfering with each other, the international telecommunication union allocates frequency bands suitable for various communication systems, corresponding values of frequencies and wavelengths of the frequency bands and names of the frequencies and the wavelengths of the frequency bands. The terminal device may determine a frequency band of a network in which the terminal device is registered according to the network information.

In one possible implementation, the Network information includes one or both of MCC (Mobile Country Code), MNC (Mobile Network Code).

The MCC is a mobile country code, which is 3 digits in total, and the MCC resources are uniformly allocated and managed by the international telecommunication union, so that the country to which the mobile subscriber belongs can be uniquely identified, for example, the MCC adopted in china is 460. The MNC is a mobile network code, 2 bits in total, and can be used to identify the mobile network to which the mobile subscriber belongs. For example, the MNC used by the Time Division (TD) System is 00, the MNC used by the GSM (Global System for Mobile communication) System is 01, the MNC used by the CSM System is 02, and the MNC used by the CDMA System is 03.

In one example, the network information is an MCC, and the network registered by the terminal device at this time is a mobile communication network of a country corresponding to the MCC. In one example, the network information is an MNC, and the network registered by the terminal device at this time is a mobile communication network corresponding to the MNC. In one example, the network information is MCC and MNC, and the network registered by the terminal device at this time is a mobile communication network corresponding to the MNC in a country corresponding to the MCC.

In a possible implementation manner, the terminal device may determine the frequency band adopted by the mobile communication by the terminal device according to the network registered by the terminal device. For example, the China Mobile GSM system includes 900MHz band and 1800MHz band, and the China telecom CDMA system includes 800MHz band. In one example, when the network information is MCC and MNC, and MCC is 460 and MNC is 2, the frequency bands corresponding to the network information are 900MHz frequency bands and 1800MHz frequency bands. When the network information is MCC and MNC, and the MCC is 460 and the MNC is 03, the frequency band corresponding to the network information is an 800MHz frequency band.

In step S13, if the frequency band corresponding to the network information is a designated frequency band, a recommended frequency corresponding to the network information is obtained, where the recommended frequency is a frequency that avoids interference with the designated frequency band.

The designated frequency band may be used to indicate a frequency band that may be interfered by MIPI frequencies. The designated frequency band may be a preset frequency band. The recommended frequency may be a frequency that avoids interference with the specified frequency band, and the recommended frequency may be determined through actual testing. When the frequency band corresponding to the network information is the designated frequency band, the MIPI communication affects the radio frequency signal, and the MIPI frequency needs to be switched, so that the influence of the MIPI communication on the radio frequency signal of the terminal device is reduced.

The number of assigned frequency bands may be one or more. The terminal device may search for a frequency band corresponding to the network information in the one or more specified frequency bands. And if the frequency band corresponding to the network information is found, determining the frequency band corresponding to the network information as the specified frequency band. In a possible implementation manner, the terminal device may search, according to the network information, a frequency band corresponding to the network information in the specified frequency band. For example, the terminal device may record network information corresponding to each designated frequency band. The terminal device may search for network information matching the network information acquired by the terminal device from the network information corresponding to the designated frequency band. If the terminal device finds the network information matched with the acquired network information, the terminal device may determine that the frequency band corresponding to the network information is the designated frequency band.

In a possible implementation manner, the terminal device may obtain a corresponding relationship between the network information and the recommended frequency by combining the corresponding relationship between the specified frequency band and the network information and the corresponding relationship between the specified frequency band and the recommended frequency. If the frequency band corresponding to the network information is the designated frequency band, the terminal device may obtain the recommended frequency corresponding to the network information according to the correspondence between the network information and the recommended frequency.

In step S14, the MIPI frequency is switched to the recommended frequency if the difference between the recommended frequency and the current frequency is less than or equal to the frequency threshold.

Wherein, the frequency threshold value can be set according to the requirement. The frequency threshold may be used to preserve the hardware of the screen and the stability of the screen display. When the MIPI frequency is excessively changed, screen flicker, heat generation, and the like may be caused, which may easily damage screen hardware and reduce screen display stability. Therefore, the terminal device may switch the MIPI frequency to the recommended frequency in a case where a difference between the recommended frequency and the current frequency is less than or equal to a frequency threshold.

Thus, the frequency band corresponding to the network information is the designated frequency band, and the frequency of the radio frequency signal is in the designated frequency band. The recommended frequency is a frequency which avoids interference with the specified frequency band, and after the terminal equipment switches the MIPI frequency to the recommended frequency, MIPI communication can avoid interference with the specified frequency band. Therefore, after the terminal device switches the MIPI to the recommended frequency, the influence of MIPI communication on the radio frequency signal quality can be reduced.

The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: in the embodiment of the present disclosure, the currently set MIPI frequency is taken as the current frequency; acquiring network information, and if the frequency band corresponding to the network information is a designated frequency band, acquiring a recommended frequency corresponding to the network information; and under the condition that the difference value between the recommended frequency and the current frequency is less than or equal to the frequency threshold, switching the MIPI frequency to the recommended frequency. According to the method for setting the MIPI frequency, the MIPI frequency can be switched to the recommended frequency according to the network environment where the terminal equipment is located, and therefore the influence of MIPI communication on the radio frequency signal quality is reduced.

In the related art, the MIPI frequency may be determined according to the resolution of a screen, the format of display data, the number of MIPI data channels, and the like. For different network environments, MIPI frequencies set by the related art are the same. At this time, MIPI communication may have a small influence on a radio frequency signal in a partial network environment, and have a large influence on a radio frequency signal in a partial network environment. In a possible implementation manner of the embodiment of the present disclosure, the terminal device may perform steps S11 to S14 each time the terminal device completes the network search and registration. Therefore, under the conditions that the terminal equipment is started, the network signal strength is changed, the access network is switched (for example, 3G is switched to 4G), and the like, the terminal equipment can switch the MIPI frequency to the recommended frequency according to the current network environment, and therefore the influence of MIPI communication on the radio frequency signal quality is reduced. When the network environment where the terminal equipment is located occurs, the frequency of the MIPI can adapt to switching, the problem of introduced sensitivity test is avoided, more flexible space design can be achieved, and better compatibility is provided.

Fig. 3 is a flowchart illustrating a method of setting MIPI frequencies according to an exemplary embodiment, and as shown in fig. 3, the method may further include the steps of:

in step S15, in a case that a difference between the recommended frequency and the current frequency is greater than the frequency threshold, the MIPI frequency is switched to the recommended frequency when the screen of the terminal device is next turned on.

As described above, too large variation in MIPI frequency may cause problems such as damage to screen hardware, instability of screen display, and the like. Therefore, in the case that the difference between the recommended frequency and the current frequency is greater than the frequency threshold, the terminal device may keep the current MIPI frequency unchanged and record the recommended frequency. And when the terminal equipment turns on the screen next time, the MIPI frequency is switched to the recommended frequency. Therefore, the problems of hardware damage, unstable display and the like caused by the change of the MIPI frequency can be solved by keeping the current MIPI frequency unchanged, and the influence of MIPI communication on the radio frequency signal quality can be reduced by switching the MIPI frequency to the recommended frequency when the screen is turned on next time.

Fig. 4 is a flowchart illustrating a method of setting MIPI frequencies according to an exemplary embodiment, as shown in fig. 4, the method may further include the steps of:

in step S21, at least one frequency band interfered by a default frequency is determined as an assigned frequency band, where the default frequency is an MIPI frequency used in the power-on process.

The default frequency may be an MIPI frequency used in the terminal device power-on process. In one possible implementation, the default frequency may be a frequency that causes the least interference to the frequency band used for mobile communications. The frequency band adopted by the mobile communication can be determined according to the frequency band division result of the international telecommunication union.

The default frequency may be determined by actual testing. The default frequency may be set to avoid the frequency bands commonly used for basic calls, such as 850MHz, 900MHz, 1800MHz, 1900MHz, etc., and the frequency with the lowest interference to other channels.

There may be one or more frequency bands interfered by the default frequency, and there may be one or more frequency bands assigned.

In step S22, for each designated frequency band, network information and recommended frequency corresponding to the designated frequency band are acquired.

In a possible implementation manner, the network information may be one or both of the MNC and the MCC, and the network information corresponding to the specified frequency band may be determined according to a frequency band division result issued by the international telecommunication union.

In one possible implementation, the recommended frequency corresponding to the designated frequency band may be determined through actual testing.

In step S23, for each designated frequency band, the correspondence between the network information corresponding to the designated frequency band and the recommended frequency corresponding to the designated frequency band is recorded.

For each designated frequency band, the terminal device may record a correspondence between network information corresponding to the designated frequency band and a recommended frequency corresponding to the designated frequency band. Therefore, after the terminal equipment can acquire the network information, the recommended frequency corresponding to the acquired network information can be searched according to the corresponding relation, and the MIPI frequency switching is carried out.

It should be noted that steps S21 to S23 may be executed before step S11.

Application example

Application scenarios: the frequency F is a default frequency, and the frequency bands (designated frequency bands) interfered by the frequency F are a frequency band 1, a frequency band 2, and a frequency band 3. As shown in table 1, the MNC corresponding to the frequency band 1 is 01, and the recommended frequency corresponding to the frequency band 1 is f 1; the MNC corresponding to the frequency band 2 is 02, and the recommended frequency corresponding to the frequency band 1 is f 2; the MNC for band 3 is 03 and the recommended frequency for band 3 is f3.

And the terminal equipment determines that the difference value between f2 and f1 is less than the frequency threshold value, and switches the MIPI frequency to f 2.

The terminal device determines that the difference between f3 and f1 is greater than the frequency threshold, maintains the MIPI frequency as f3, and records f 1. When the screen of the terminal device is lighted again, the terminal device can switch the MIPI frequency to f 1.
