At the beginning, most of the movies were screened in special venues, such as movie theaters. With the development of electronic devices and the development of communication technology, electronic devices such as smartphones have also become devices for the regular playback of movies. Compared with the configuration in movie theaters, electronic devices The video processing capabilities of movies are much worse. But for movies, the user experience includes video experience and audio experience. For video experience, the improvement is mainly through the display screen technology. Since the display of current electronic devices is also based on 2D display technology, it is mainly for the clarity of the movie Claim. For electronic devices, taking a smartphone as an example, most of them are equipped with a communication demodulator modem. The modem will periodically report the modem's operating frequency, which may interfere with the MIPI frequency of the display screen. Interference will inevitably affect the display effect of the display screen, thus affecting the user's experience with movie videos.

The following describes the embodiments of the present application in detail.

Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a method for adjusting the operating frequency of a display screen MIPI disclosed in an embodiment of the present application. The method is applied to the electronic device described in FIG. 1. The method for adjusting the operating frequency of the display screen MIPI includes the following steps:

Step S201: In the bright screen state, the electronic device receives the data packet and identifies the type of the data packet;

There may be multiple methods for confirming the bright screen state. For example, in an optional embodiment, the bright screen state may be determined by whether the electronic device is unlocked, that is, the unlocked state is the bright screen state, and the non-unlocked state is Non-bright screen state.

Of course, the above method for confirming the bright screen state can also be confirmed by other methods, for example, detecting the current brightness of the screen, if the current brightness is greater than the set brightness threshold, it is determined to be in the bright screen state, if the current brightness is less than the set brightness threshold, it is determined to be in Breath screen status (non-bright screen status). Of course, the above determination method of the bright screen can also be confirmed by other methods, and this application does not limit the specific confirmation method of the above bright screen state.

The above method for receiving data packets by the electronic device can be received through a mobile communication network, including but not limited to: 2G, 3G, 4G, 5G and other standard protocol mobile communication networks. Of course, in practical applications, other methods can also be used. Reception, for example, through wifi, Bluetooth, etc.

The above-mentioned identification of the type of the data packet may specifically include:

Identify the data packet to determine the first format of the data packet, and determine whether the first format is the format of the non-live video service. If the first format belongs to the format of the non-live video service, determine that the data packet is a non-video service data packet Otherwise, it is determined that the data packet is not a non-video service data packet.

The suffixes of the above non-video service formats include, but are not limited to: vob, ifo, mpg, mpeg, dat, mp4, 3gp, mov, rm, ram, rmvb, wmv, asf, avi, asx.

Specifically, the above identification of the type of the data packet may further include:

Obtain the first application that parses the data packet, determine whether the first application belongs to an application of non-live video services, for example, determine that the first application belongs to non-live video services, determine that the data packet belongs to non-live video services, if determine that the first application Belong to the non-live video service, determine that the data packet does not belong to the non-live video service.

For example, if it is determined that the first application for parsing the data packet is an instant messaging application, since the instant messaging application belongs to a live video service application, it is determined that the data packet does not belong to a non-live video service. Resolve it if you are sure

Step S202: When the electronic device recognizes that the type of the data packet is a non-live video service data packet, it adjusts the reporting period of the operating frequency of the modem to the first period corresponding to the non-live video service;

Optionally, the adjustment of the reporting period of the working frequency point of the modem to the first period corresponding to the non-live video service may specifically include:

Query the first cycle corresponding to the non-live video service from the mapping relationship between the service and the reporting frequency of the working frequency, and report the period adjustment value of the working frequency of the modem to the first cycle. The specific adjustment method may be to extend the reporting period of the working frequency point, that is, by extending the reporting period to reduce the number of interferences between the modem's working frequency point and the display MIPI frequency, which can reduce the number of MIPI interferences on the display screen and reduce the interference.

Step S203: The electronic device adjusts the MIPI frequency of the display screen according to the current operating frequency of the modem.

The implementation method of the above step S203 may specifically be:

The electronic equipment is pre-configured with the interference frequency lists desense_list_1 ~ desense_list_n corresponding to the display screen MIPI operating frequencies freq_1 ~ freq_n, and the MIPI frequency range lists freq_list_1 ~ freq_list_n corresponding to different user scenarios scenario_1 ~ scenario_n;

The electronic device determines the modem interference frequency corresponding to each MIPI frequency in freq_list_target according to the freq_list_target display freq_list_target corresponding to the non-live video service in freq_list_1 to freq_list_n. The MIPI frequency of the display is adjusted to the first frequency.

This technical solution queries the minimum interference frequency of the modem operating frequency by querying a pre-configured list. In this way, the corresponding first frequency is selected to prevent the modem operating frequency from interfering with the MIPI frequency of the display screen and improve the non-live video service of the display screen. Clarity.

It should be noted that the above freq_list_1 ~ freq_list_n may be a list composed of some mapping relationships, and the above freq_list_1 ~ freq_list_n may also be a list composed of some mapping relationships.

When the technical solution provided by this application is in the bright screen state, it identifies whether the received data packet belongs to a non-live broadcast video data packet. If it belongs to a non-live broadcast video data packet, the reporting period of the modem's working frequency is reduced. Adjust the MIPI frequency of the display screen to avoid interference between the operating frequency of the modem and the MIPI frequency. This avoids MIPI frequency interference, improves the clarity of the display screen, and improves the user experience.

Optionally, the above method may further include:

Detect the resolution corresponding to each MIPI frequency in freq_list_target, determine the reporting time of the modem according to the first period Set the frequency to the second frequency. If the current time belongs to the reporting time, set the MIPI frequency of the display to the first frequency.

For this technical solution, since the period of the modem is adjusted to report according to the first period, the specific time for the modem to report can be determined. The interference between the modem operating frequency and the MIPI frequency will only occur at the time of reporting, and at the time of non-reporting , Because the modem does not work, its operating frequency is 0, and it will not interfere with the MIPI frequency. Therefore, at a non-reporting time, you can choose the second frequency with the highest resolution to work without having to consider modem interference, so it improves This improves the clarity of non-live video services, and further improves the user experience of watching non-live video services.

Optionally, the above method may further include:

This technical solution can reduce the frequency of MIPI frequency adjustment of the display screen. For non-live video services, movies are used as an example. For movie videos, it generally includes two parts, namely, the advertising part and the non-advertising part (generally the positive segment of the movie) For the user experience, the clarity and interference of the advertising part will not affect the viewing experience, so if it is determined that it is in the advertising part, it can be directly adjusted without any interference, and it is just that the viewing effect of the advertisement is just a little bit worse. Will not affect the viewing of the original film.

The above identification of the multiple pictures to determine the types of the multiple pictures may specifically include:

The method for recognizing the icons within the set range may specifically be implemented by a classifier, which includes, but is not limited to, machine learning classifiers, such as neural network models, deep learning models, support vector machines, etc. Classification model.

For this solution, the idea is that for the advertising part, in order to improve the effectiveness of the advertisement, the position of the trademark in most of the advertisements is near the center point. If the entire picture is entered into the classification model for recognition, because the picture There are many pixels, so it will increase the amount of calculation. Therefore, according to the characteristics of the advertisement, input the pictures within the range of the center point to the corresponding classification model for classification can effectively reduce the amount of calculation and improve the calculation efficiency.

For this solution, the idea is that most of the pictures of the advertisement will appear in the shape of the product, such as the shape of the packaging. Taking the shampoo as an example, most of the shampoo advertisements will appear in the packaging of the shampoo. The packaging, most of its RGB value is the same color, and the external lines are relatively fixed, such as straight lines or arcs of the same arc, then by determining the edge line, you can recognize whether the set range includes packaging, and for the positive film , There is rarely a large area of packaging in the center, so this way you can distinguish between advertising parts.

Referring to FIG. 3, FIG. 3 provides a method for adjusting the operating frequency of the display screen MIPI. The method is shown in FIG. 3 and includes the following steps:

Step S301: The electronic device detects the current brightness value of the screen, if the brightness value is greater than the brightness threshold, determines that it is in a bright screen state, and recognizes the type of the received data packet;

Step S302: When the electronic device recognizes that the type of the data packet belongs to a movie data packet, it adjusts the reporting period of the operating frequency of the modem to the first period corresponding to the movie;

Step S303: The electronic device determines multiple reporting time points according to the first period, and determines the modem interference frequency corresponding to each MIPI frequency in freq_list_target based on the freq_list_target of the display screen MIPI frequency list corresponding to the non-live video services in freq_list_1 ~ freq_list_n, From freq_list_target, select the first frequency that has no or minimal interference with modem;

Step S304: The electronic device obtains multiple pictures of the non-live video service corresponding to the multiple reporting time points, and identifies the multiple pictures to determine the types of the multiple pictures. If the multiple pictures belong to the type of advertisement, do not change the Display screen MIPI frequency, if the multiple pictures belong to non-advertising type, adjust the display screen MIPI frequency to the first frequency.

When the technical solution provided by this application is in the bright screen state, it identifies whether the received data packet belongs to a non-live broadcast video data packet. If it belongs to a non-live broadcast video data packet, the reporting period of the modem's working frequency is reduced. In addition, according to the working frequency of the modem Adjust the MIPI frequency of the display screen to avoid interference between the operating frequency of the modem and the MIPI frequency. This avoids MIPI frequency interference, improves the clarity of the display screen, and improves the user experience.

Optionally, the processing unit is also used to detect the resolution corresponding to each MIPI frequency in freq_list_target, and determine the reporting time of the modem according to the first period. If the current time belongs to a non-reporting time, search for the highest resolution from freq_list_target Set the MIPI frequency of the display to the second frequency.
