Among them, the above video mode includes the electronic device in a live video mode or the electronic device in a video call mode. The video call mode includes a mode in which the electronic device makes a video call through a third-party application, or the electronic device is based on a long-term evolution voice service Long term (Evolution, VOLTE) video call mode. In the embodiment of the present application, when the electronic device is in the video mode, the frame rate and resolution of the display screen of the display screen are high, and the real-time requirement of the transmission data of the display screen is high.

11. Obtain the moving speed of the electronic device;

12. If the moving speed meets the preset speed range, determine a target time period according to the moving speed, and receive the target operating frequency reported by the modem in the target time period.

In the embodiments of the present application, it is considered that when the electronic device is in the video mode, the display frame rate and resolution requirements are high, the network real-time requirement is high, and the power consumption of the electronic device is high. If the modem continues to report to the AP at high frequency The target operating frequency will increase the data processing pressure of the AP and increase power consumption. Therefore, the speed detection device of the electronic device, such as a speed sensor, can be used to detect the moving speed of the electronic device. If the moving speed belongs to the preset speed range, Determine the target time period corresponding to the moving speed according to the mapping relationship between the preset speed and the time period, and control the modem to report the target operating frequency to the AP according to the target time period, specifically, when the first moving speed is greater than the second moving speed, The first time period corresponding to the first moving speed is less than the second time period corresponding to the second moving speed, so that the time period for the modem to report the target operating frequency can be flexibly adjusted according to the different moving speeds of the electronic device, saving the electronic device Power consumption.

Optionally, when the electronic device is in a screen-off state, the operation of the modem to report the target operating frequency may be stopped, thereby reducing the power consumption of the electronic device.

102. Obtain the first MIPI working frequency of the processor interface MIPI of the display screen mobile industry.

In the embodiment of the present application, the application processor AP may obtain the first MIPI working frequency of the display MIPI bus according to the time period of the target working frequency, and when the detection period of the target working frequency is adjusted from the first time period to the second time period, The time period for obtaining the first MIPI operating frequency can also be adjusted accordingly.

103. Determine whether the target operating frequency is interfered according to the first MIPI operating frequency.

In the embodiment of the present application, after receiving the target operating frequency of the modem and acquiring the first MIPI operating frequency, the application processor AP may determine whether the target operating frequency is affected by the first MIPI operating frequency according to the target operating frequency and the first MIPI operating frequency Interference.

Optionally, in step 103 above, determining whether the target operating frequency is interfered according to the first MIPI operating frequency may include the following steps:

31. Determine a target interference frequency list corresponding to the first MIPI operating frequency according to a preset correspondence between the MIPI operating frequency and the interference frequency list, the target interference frequency list including the first MIPI operating frequency Corresponding multiple first interference frequencies;

32. Match the target operating frequency with the plurality of first interference frequencies in the target interference frequency list in sequence, if the target operating frequency and any first interference among the plurality of first interference frequencies The frequency matching is successful, and it is determined that the target operating frequency is interfered.

Among them, the electronic device can obtain multiple interference frequency lists of the display screen MIPI under multiple MIPI operating frequencies in advance, each MIPI operating frequency corresponds to an interference frequency list, and each interference frequency list includes multiple interference frequencies, and then set the MIPI Correspondence between the operating frequency and the interference frequency list, so that after acquiring the first MIPI operating frequency, a first interference frequency list corresponding to the first MIPI operating frequency can be determined, the first interference frequency list includes working with the first MIPI The multiple first interference frequencies corresponding to the frequency indicate that the first MIPI operating frequency will interfere with any first interference frequency among the multiple first interference frequencies, where each first interference frequency among the multiple first interference frequencies is Refers to the operating frequency at which the modem will be disturbed during communication.

Among them, the target operating frequency of the modem may be sequentially matched with multiple first interference frequencies in the target interference frequency list, and if there is a first interference frequency equal to the target operating frequency among the multiple first interference frequencies, the matching is successful, That is, the target operating frequency of the modem falls within the range of the target interference frequency list, and it is determined that the target operating frequency is interfered by the first MIPI operating frequency.

104. If yes, obtain the target video frame rate of the video.

The target video frame rate is the video frame rate of the video to be displayed obtained by the camera of the current electronic device. In the embodiment of the present application, if it is determined that the target working frequency of the modem is interfered, the target video frame rate of the video may be obtained.

105. Determine a second MIPI operating frequency corresponding to the target video frame rate, the interference of the second MIPI operating frequency on the target operating frequency is less than that of the first MIPI operating frequency on the target operating frequency interference.

Considering that different video frame rates have different requirements on the MIPI operating frequency, the second MIPI operating frequency corresponding to the current target video frame rate can be determined, so that the display MIPI works at the second MIPI operating frequency, which can guarantee the video The target video frame rate is displayed normally, and the interference caused by the second MIPI operating frequency to the target operating frequency is smaller than the interference caused by the first MIPI operating frequency to the target operating frequency, thereby reducing the operating interference to the modem.

Optionally, in step 105 above, determining the second MIPI operating frequency corresponding to the target video frame rate may include the following steps:

51. Determine a target MIPI working frequency range list corresponding to the target video frame rate, where the target MIPI working frequency range list includes multiple MIPI working frequencies;

52. Determine the interference intensity value of each MIPI operating frequency of the multiple MIPI operating frequencies to the target operating frequency to obtain multiple interference intensity values;

53. Determine a second MIPI operating frequency corresponding to an interference intensity value less than a preset threshold among the multiple interference intensity values.

Wherein, if the target MIPI working frequency range list corresponding to the target video frame rate is determined, the display screen MIPI can work at the MIPI working frequency within the target MIPI working frequency range list range, thereby ensuring that the current video is under the target video frame rate Stable display.

In the embodiment of the present application, after determining the target MIPI operating frequency range list corresponding to the target video frame rate, since the target MIPI operating frequency range list includes multiple MIPI operating frequencies, the interference intensity value for the modem's target operating frequency can be further determined The second MIPI operating frequency is less than the preset threshold, so that the interference of the MIPI operating frequency of the display screen on the target operating frequency of the modem can be reduced, and better communication performance can be obtained.

Optionally, in the above step 51, determining the target MIPI working frequency range list corresponding to the target video frame rate may include the following steps:

The target MIPI working frequency range list corresponding to the target video frame rate is determined according to the correspondence between the preset video frame rate and the MIPI working frequency range list.

Among them, the electronic device can obtain in advance multiple MIPI operating frequency range lists at multiple video frame rates, each game frame rate corresponds to a MIPI operating frequency range list, and then set the video frame rate between the MIPI operating frequency range list Correspondence relationship, thus, after acquiring the target video frame rate of the video, a list of target MIPI operating frequency ranges corresponding to the target video frame rate can be determined, and the target MIPI operating frequency range list includes multiple MIPI operating frequencies corresponding to the target video frame rate In this way, the display screen MIPI operates at any MIPI operating frequency among multiple MIPI operating frequencies, which enables the video to be displayed stably at the target video frame rate.

54. Determine a target MIPI operating frequency range list corresponding to the target video frame rate, the target MIPI operating frequency range list includes multiple MIPI operating frequencies;

55. Determine a reference interference frequency list corresponding to each MIPI working frequency of the plurality of MIPI working frequencies according to a preset correspondence relationship between the MIPI working frequency and the interference frequency list, and obtain multiple reference interference frequency lists;

56. Match the target operating frequency with multiple interference frequencies in each reference interference frequency list in the multiple reference interference frequency lists to obtain a matching result corresponding to the second interference frequency list;

57. If the matching result is that all the interference frequencies in the second interference frequency list and the target operating frequency have failed to match, determine according to the correspondence between the MIPI operating frequency and the interference frequency list. The second MIPI operating frequency corresponding to the second interference frequency list.

Among them, the reference interference frequency list corresponding to each MIPI operating frequency in the above multiple MIPI operating frequencies can be determined according to the correspondence between the preset MIPI operating frequency and the interference frequency list to obtain multiple reference interference frequency lists. A MIPI operating frequency and its corresponding reference interference frequency list, which can match the target operating frequency with multiple interference frequencies in the reference interference frequency list in turn, if there are multiple interference frequencies in the reference interference frequency list that work with the target If the interference frequencies are equal, the match is successful. Furthermore, it can be determined that the target operating frequency falls within the range of the reference interference frequency list, so that multiple reference interference frequency lists can be determined, and the target operating frequency does not fall within the reference interference frequency list. The second interference frequency list in the range, that is, the target operating frequency and all interference frequencies in the second interference frequency list fail to match. Therefore, it can be determined that the second MIPI operating frequency corresponding to the second interference frequency list is the target of the modem The working frequency interferes with the MIPI working frequency with less interference.

106. Adjust the MIPI operating frequency of the display screen to the second MIPI operating frequency.

In the embodiment of the present application, after determining the second MIPI operating frequency, the MIPI operating frequency of the display screen MIPI can be adjusted from the first MIPI operating frequency to the second MIPI operating frequency, so that the display MIPI to modem communication can be eliminated or reduced Electromagnetic interference to obtain the best communication performance.

Further, in the process of adjusting the MIPI working frequency of the display screen, the display parameters of the display screen can also be adjusted to ensure the stable operation of the display screen.

Optionally, in the embodiment of the present application, when the MIPI working frequency of the display screen is adjusted to the second MIPI working frequency, the following steps may be further included:

A1, when the change amount of the frame rate of the display screen after the MIPI frequency switching is less than the first preset threshold, determine the reference screen parameter of the display screen according to the preset frame rate calculation formula and the second MIPI operating frequency value;

A2. Dynamically adjust the screen parameters of the display screen according to the reference screen parameter values to obtain the target screen parameter values, the screen parameters including at least one of the following porch values in the preset frame rate calculation formula: horizontal trailing edge HBP, horizontal leading edge HFP, vertical trailing edge VBP, vertical leading edge VFP, width of vertical synchronization signal VSA, width of horizontal synchronization signal HAS.

Wherein, the preset frame rate calculation formula is the following formula:

FPS ＝ CLK_rate * 2 * lane_num / ((height + VBP + VSA + VFP) * (weight + HBP + HFP + HSA) * bits_perpixel)

Among them, FPS indicates the frame rate of the display screen, CLK_rate indicates the MIPI frequency, lane_num indicates the number of channels, height and weight indicate the physical size of the display screen, VBP (vertical backporch) indicates that the vertical sync signal is invalid after the start of a frame of image The number of lines, VFB (vertical front porch) indicates the number of invalid lines before the vertical sync signal after the end of a frame, VSA (vertical sync) indicates the width of the vertical sync signal, and HBP (horizontal backporch) indicates the horizontal line. The number of clocks from the start of the synchronization signal to the start of the effective data of a line, HFP (horizontal frontporth) represents the number of clocks from the end of the effective data of a line to the start of the next horizontal synchronization signal, HSA (horizontal syncactive) : Indicates the width of the horizontal synchronization signal, bits_perpixel indicates the width of RGB display data.

Wherein, the first preset threshold may be an empirical value, which is used to ensure the stability of the content display of the display screen before and after the frequency switching, such as the maximum allowable error range of the display chip of 1%.

It can be seen that in the embodiment of the present application, after the frequency hopping is switched on by the electronic device, some parameters of the display screen of the electronic device will be changed, and the frame rate is an important parameter index to ensure the stability of the display after the frequency hopping switching of the display screen. The electronic device can pre-determine the reference screen parameter value of the screen parameter that needs to be synchronously adjusted during the frequency hopping process based on the frame rate formula. The electronic device can first adjust the screen parameter to the reference screen parameter value, and based on the reference screen parameter value Further dynamically adjust the screen parameters to finally reach the target screen parameter value, thereby improving the display stability of the display.

Optionally, in the above step A2, the screen parameters include horizontal screen parameters, and the horizontal screen parameters include at least one of the following: the HBP, the HFP, and the HAS; wherein, according to the reference screen parameter value Dynamically adjusting the screen parameters of the display screen to obtain the target screen parameter values may include the following steps:

The horizontal screen parameter of the display screen is dynamically adjusted according to the reference screen parameter value, so that the change amount of the line scan duration of the display screen after the MIPI frequency switching is less than the second preset threshold.

Wherein, if the screen parameter is a horizontal screen parameter, the electronic device may first adjust the horizontal screen parameter to the reference screen parameter value, and further dynamically adjust the screen parameter based on the reference screen parameter value, so that the line scan duration of the display screen is at The amount of change after MIPI frequency switching is less than the second preset threshold, thereby improving the display stability of the display.

For example, when the MIPI main frequency of the display is 514.5MHz, the line scan time is 7.18us, and when the MIPI frequency is switched to the auxiliary frequency of 529MHz, fine-tuning is performed according to the reference value of the screen parameter, and the line scan time is measured simultaneously to determine the line scan. The value of the screen parameter after the fine-tuning under the time of 7.18us is the target value. This is mainly because the above preset frame rate calculation formula is only a theoretical calculation formula. In fact, due to the physical difference of the device, the accuracy of this reference value is not very high, and the actual MIPI transmission frequency and the value of the screen parameter are different. Large (the difference between MHz and tens and hundreds), and the horizontal screen parameters of the display screen have a greater impact on the display stability, so consider modifying the value of the horizontal screen parameters based on the actual detection results to improve stability.

In addition, if the screen parameters include only vertical screen parameters, and the vertical screen parameters include at least one of the following: the VBP, the VFP, and the VAS, the target screen parameter value may be equal to the reference screen parameter The value, that is, adjusting the porch value in the vertical direction has no effect on the line scan duration.

It can be seen that in the embodiment of the present application, in the case where the screen parameters include the horizontal screen parameters, the electronic device can modify the reference screen parameter value according to the constraint condition of the line scan duration and the actual detection result, thereby improving the stability of the display screen after frequency hopping.

It can be seen that the electromagnetic interference control method described in the embodiments of the present application obtains the target operating frequency of the modem and the first MIPI operation of the MIPI of the display screen when the electronic device is in the video mode and the display screen is bright. Frequency, determine whether the target operating frequency is disturbed according to the first MIPI operating frequency, if so, determine the target video frame rate of the video, determine the second MIPI operating frequency corresponding to the target video frame rate, and adjust the MIPI operating frequency of the display to all The second MIPI operating frequency is described. In this way, the MIPI operating frequency of the display screen can be dynamically adjusted when the electronic device is in the video mode without changing the hardware design of the electronic device, thereby eliminating or reducing its electromagnetic interference to modem communication, and obtaining the most Good communication performance.

Consistent with the above, FIG. 2 is a schematic flowchart of an electromagnetic interference control method disclosed in an embodiment of the present application.

206. Adjust the MIPI working frequency of the display screen to the second MIPI working frequency.

207. When the change amount of the frame rate of the display screen after the MIPI frequency switching is less than the first preset threshold, determine the reference screen parameter of the display screen according to the preset frame rate calculation formula and the second MIPI operating frequency value.

208. Dynamically adjust the screen parameters of the display screen according to the reference screen parameter values to obtain the target screen parameter values, the screen parameters including at least one of the following porch values in the preset frame rate calculation formula: horizontal trailing edge HBP, horizontal leading edge HFP, vertical trailing edge VBP, vertical leading edge VFP, width of vertical synchronization signal VSA, width of horizontal synchronization signal HAS.

For the specific description of the above steps 201 to 208, reference may be made to the corresponding description of the electromagnetic interference control method described in FIG. 1B, which will not be repeated here.
