In order to illustrate the technical solutions described in this application, specific examples are used below to illustrate.

Referring to FIG. 1 , it is a schematic diagram of the implementation flow of the clock signal frequency hopping method provided in Embodiment 1 of the present application. The frequency hopping method is applied to a mobile terminal. As shown in the figure, the frequency hopping method may include the following steps:

Step S101, when jumping the first frequency of the clock signal of the display screen of the mobile terminal to the target frequency of the clock signal, acquiring the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal.

In the embodiment of this application, the transfer of the interference frequency point can be realized by jumping two frequencies of the clock signal of the display screen. For example, the first frequency of the clock signal is A, and the target frequency of the clock signal is B. If channel 1 has interference, then the interference to channel 1 can be eliminated by switching from A to B. Similarly, if B interferes with channel 2, then the interference to channel 2 can be eliminated by switching B to A. At this time, B is the first frequency of the clock signal, and A is the target frequency of the clock signal.

Step S102, dividing the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal into N segments, where N is an integer greater than 1.

For broadband communication (such as LTE), due to the wide bandwidth, directly jumping the first frequency of the clock signal to the target frequency of the clock signal may affect the repair or recovery of the frame rate of the display screen. In order to avoid the impact of frequency hopping The display screen, at this time, the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal can be divided into N segments, so as to ensure a narrow bandwidth between adjacent frequency points. For example, the first frequency of the clock signal is 514.5MHz, the target frequency of the clock signal is 529MHz, the bandwidth between 514.5MHz and 529MHz is divided into four sections, the first section is 514.5MHz~517.5MHz, and the second section is 517.5MHz ~520.5MHz, the third section is 520.5MHz~525.5MHz, and the fourth section is 525.5MHz~529MHz.

Step S103 , jumping the first frequency of the clock signal to the target frequency of the clock signal after N times of hopping according to the divided N bandwidths.

In the embodiment of the present application, after dividing the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal into N segments, the bandwidth of each jump of the frequency of the clock signal can be reduced, so that through multiple steps Type hopping realizes wideband hopping. Wherein, the step jump may refer to realizing multiple jumps in a manner like climbing stairs.

In this embodiment of the application, the user can set the value of N by himself, or the value of N is preset by the system, or the mobile terminal can set the value of N according to the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal and the bandwidth of each segment after segmentation. Bandwidth requirements, set the value of N, which is not limited here. For example, the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal is 30 MHz, and it is required that the bandwidth of each segment after segmentation does not exceed 8 MHz, then N can be set to 5 or greater than 5.

In the embodiment of the present application, by jumping the first frequency of the clock signal to the target frequency of the clock signal after N times of step jumps, wide-band jumps can be realized. Since the frequency band of each jump is narrowed, it can be While realizing the jump of the broadband, realize the restoration of the frame rate of the display screen.

Referring to FIG. 2 , it is a schematic diagram of the implementation flow of the clock signal frequency hopping method provided in Embodiment 2 of the present application. The frequency hopping method is applied to a mobile terminal. As shown in the figure, the frequency hopping method may include the following steps:

Step S201, when jumping the first frequency of the clock signal of the display screen of the mobile terminal to the target frequency of the clock signal, acquiring the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal.

In the embodiment of this application, the transfer of the interference frequency point can be realized by jumping two frequencies of the clock signal of the display screen. For example, the first frequency of the clock signal is A, and the target frequency of the clock signal is B. If channel 1 has interference, then the interference to channel 1 can be eliminated by switching from A to B. Similarly, if B interferes with channel 2, then the interference to channel 2 can be eliminated by switching B to A. At this time, B is the first frequency of the clock signal, and A is the target frequency of the clock signal.

Optionally, the embodiment of this application also includes:

The mobile terminal uses a Long Term Evolution LTE network;

A bandwidth between the first frequency of the clock signal and the target frequency of the clock signal exceeds a maximum value of an LTE bandwidth.

In the embodiment of the present application, due to the wide bandwidth of the LTE frequency band, in order to prevent the frequency point that interferes with LTE between the first frequency of the clock signal and the target frequency of the clock signal, the first frequency of the clock signal and the target frequency of the clock signal are set. When determining the target frequency of the clock signal, it is necessary to ensure that the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal exceeds the maximum value of the LTE bandwidth. Since common LTE bandwidths are 1.4MHz, 2.5MHz, 5MHz, 10MHz, 15MHz, and 20MHz, the maximum LTE bandwidth can be 20MHz.

Step S202, dividing the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal into N segments, where N is an integer greater than 1.

For broadband communication (such as LTE), due to the wide bandwidth, jumping the first frequency of the clock signal directly to the target frequency of the clock signal may affect the repair of the frame rate of the display screen. In order to avoid the frequency jump from affecting the display screen , at this time, the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal can be divided into N segments, so as to ensure a narrow bandwidth between adjacent frequency points. For example, the first frequency of the clock signal is 514.5MHz, the target frequency of the clock signal is 529MHz, the bandwidth between 514.5MHz and 529MHz is divided into four sections, the first section is 514.5MHz~517.5MHz, and the second section is 517.5MHz ~520.5MHz, the third section is 520.5MHz~525.5MHz, the fourth section is 525.5MHz~529MHz, 514.5MHz, 517.5MHz, 520.5MHz, 525.5MHz and 529MHz can correspond to a frequency point respectively, according to the first frequency of the slave clock signal The sequence from the frequency to the target frequency of the clock signal specifies that the first frequency point corresponds to 514.5MHz, the second frequency point corresponds to 517.5MHz, the third frequency point corresponds to 520.5MHz, the fourth frequency point corresponds to 525.5MHz, and the fifth frequency point corresponds to 525.5MHz. The frequency corresponds to 529MHz.

Optionally, dividing the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal into N segments includes:

Divide the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal into N segments equally.

In the embodiment of the present application, the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal can be divided into N sections on average, and each section has the same bandwidth. As shown in Figure 3a, the first frequency A of the clock signal and The bandwidth 24MHz between the target frequency B of the clock signal is divided into four sections, each section has a bandwidth of 6MHz, B1 is the second frequency, B2 is the third frequency, B3 is the fourth frequency, and t is to jump the first frequency to the target The total time of frequency, t1 is the time to hop the first frequency A to the second frequency B1, t2 is the time to hop the second frequency B1 to the third frequency B2, t3 is the time to hop the third frequency B2 to the fourth frequency B3 t4 is the time for jumping the fourth frequency B3 to the target frequency B, and t is the sum of t1, t2, t3 and t4.

Optionally, dividing the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal into N segments includes:

Unequally divide the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal into N segments.

In the embodiment of the present application, the bandwidth between the first frequency of the clock signal and the target frequency of the clock signal can be divided into N segments unevenly, and the bandwidths of the N segments are not completely the same (for example, when the segments start from the first frequency of the clock signal , each segment of bandwidth is incremented by 1MHz), as shown in Figure 3b, the bandwidth 22MHz between the first frequency A of the clock signal and the target frequency B of the clock signal is divided into four segments, the bandwidth between A and B1 is 4MHz, and the bandwidth between B1 and The bandwidth between B2 is 5MHz, the bandwidth between B2 and B3 is 6MHz, the bandwidth between B3 and B is 7MHz, B1 is the second frequency, B2 is the third frequency, B3 is the fourth frequency, t is the The total time for jumping from one frequency to the target frequency, t1 is the time for jumping the first frequency A to the second frequency B1, t2 is the time for jumping the second frequency B1 to the third frequency B2, t3 is the time for jumping the third frequency B2 The time to the fourth frequency B3, t4 is the time to hop the fourth frequency B3 to the target frequency B, and t is the sum of t1, t2, t3 and t4.

Step S203, jumping the first frequency of the clock signal to the second frequency of the clock signal.

Wherein, the N sections of bandwidth correspond to N+1 frequency points, the first frequency point corresponds to the first frequency of the clock signal, the second frequency point corresponds to the second frequency of the clock signal, and so on, the N+th 1 frequency point corresponds to the target frequency of the clock signal;

Step S204, jumping the second frequency of the clock signal to the third frequency of the clock signal.

Step S205, and so on until the Nth frequency of the clock signal is jumped to the target frequency of the clock signal.

Exemplarily, when the first frequency of 514.5MHz of the clock signal is jumped to the target frequency of 529MHz of the clock signal after four step jumps, the first frequency of 514.5MHz can be jumped to 517.5MHz, and then 517.5MHz can be jumped to 520.5MHz MHz, jump from 520.5MHz to 525.5MHz, and finally jump from 525.5MHz to 529MHz. Since the bandwidth of each jump is narrow (for example, less than 20M becomes a narrow bandwidth), it can effectively avoid the impact on the display.

Optionally, the embodiment of this application also includes:

The time for each jump of the frequency of the clock signal does not exceed the frame rate recovery time of the display screen, wherein the frame rate recovery time of the display screen refers to after the frequency of the clock signal of the display screen changes, Fix the timing of self display effects.

In the embodiment of the present application, by controlling the frequency of the clock signal to jump each time to not exceed the frame rate recovery time of the display screen, it can be ensured that the display of the display screen will not be affected when the frequency of the clock signal jumps each time, and the control of the display screen can be realized. Framerate fixes. As shown in Fig. 3a, t1, t2, t3 and t4 all do not exceed the frame rate restoration time of the display screen.

Optionally, the embodiment of this application also includes:

The total time for the first frequency of the clock signal to jump to the target frequency of the clock signal after N times of hopping is less than the time for establishing communication, wherein the time for establishing communication means that the base station establishes communication with the mobile terminal The time of connection.

In the embodiment of the present application, by controlling the first frequency of the clock signal to jump to the target frequency of the clock signal after N jumps, the total time spent (t in Fig. 3a) is less than the time for establishing communication, thereby ensuring There is no interference after a communication handover (for example, switching from one channel to another, requiring the base station to re-establish a communication connection with the mobile terminal).

In the embodiment of the present application, by jumping the first frequency of the clock signal to the target frequency of the clock signal after N times of step jumps, wide-band jumps can be realized. Since the frequency band of each jump is narrowed, it can be While realizing the jump of the broadband, realize the restoration of the frame rate of the display screen.
