[0038] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] In one embodiment, Figure 1 As shown, a display frequency conversion method is provided. This embodiment is illustrated by applying the method to an application processor of an electronic device. In this embodiment, the method includes the following steps:

[0040] S201, determining a target frame rate corresponding to a display screen of the electronic device according to operating parameters of the electronic device.

[0041] The operating parameters of the electronic device may include the temperature of the electronic device and / or the load of the electronic device, etc. The temperature change of the electronic device may be caused by the load change of the central processing unit (CPU) of the electronic device during operation, for example, the CPU is overloaded or the load is reduced, etc., or it may be caused by the change of the temperature of the environment in which the electronic device is located. Optionally, the load of the electronic device may be related to the number of applications running on the electronic device, or it may be related to the frame rate of the applications running on the electronic device.

[0042] In an embodiment of the present application, the frame rate of the display screen of the electronic device is the number of times the display screen refreshes the image per second, in Hz. Among them, the smoothness of the screen display is related to the frame rate of the display screen, and the higher the frame rate, the higher the smoothness of the screen display. Optionally, the display screen in the embodiment of the present application can be a display screen that supports N-frequency division, wherein N is a positive integer, and the variable frame rate of the display screen = the base frequency frame rate of the display screen * N / (N+M), M≥0, M is an integer, and taking the basic frame rate of the display screen as 120Hz as an example, assuming that the display screen supports 3-frequency division, the variable frame rate of the display screen can be 120Hz, 90Hz, 72Hz, 60Hz, 51Hz, 40Hz...

[0043] Optionally, in this embodiment, the change information of the operating parameters can be determined according to the operating parameters of the electronic device, and then the target frame rate corresponding to the display screen of the electronic device can be determined based on the change information of the operating parameters. Taking the operating parameters including temperature as an example, it can be determined whether the temperature of the electronic device is increased or decreased according to the temperature of the electronic device. If it is determined that the temperature of the electronic device is increased, the initial frame rate of the display screen of the electronic device can be reduced to determine the target frame rate. If it is determined that the temperature of the electronic device is decreased, the initial frame rate of the display screen of the electronic device can be increased to determine the target frame rate. It can be understood that if the operating parameters of the electronic device include load, the target frame rate corresponding to the display screen of the electronic device can also be determined based on this principle. It can be understood that in this embodiment, the finer the granularity of the operating parameters of the electronic device, the finer the granularity of the determined target frame rate, so that the display screen of the electronic device can perform smoother frame rate switching.

[0044] It should be noted that the target frame rate determined in this embodiment is the frame rate supported by the display screen of the electronic device. Optionally, the determined target frame rate can be the baseband frame rate of the display screen or the high-precision variable frequency frame rate of the display screen. This embodiment does not limit the type of the determined target frame rate.

[0045] S202: Generate a frame rate adjustment instruction according to the target frame rate and the initial frame rate of the display screen.

[0046] Optionally, in this embodiment, the application processor may determine how to adjust the initial frame rate of the display screen to the target frame rate based on the difference between the target frame rate and the initial frame rate of the display screen, and then generate a frame rate adjustment instruction based on the determined adjustment method. Exemplarily, if the difference between the target frame rate and the initial frame rate is less than a preset threshold, the application processor may determine to adjust the initial frame rate to the target frame rate by frequency hopping, and the generated frame rate adjustment instruction may be a frequency hopping instruction; if the difference between the target frame rate and the initial frame rate is greater than the preset threshold, the application processor may determine to adjust the initial frame rate to the target frame rate by frequency hopping first and then by frequency conversion, and the generated frame rate adjustment instruction may be an adjustment instruction that first indicates frequency hopping and then indicates frequency conversion.

[0047] S203, sending a frame rate adjustment instruction to the display driver chip; the frame rate adjustment instruction is used to instruct the display driver chip to adjust the frame rate of the display screen.

[0048] Among them, the display driver chip is used to drive the display screen to display images, and has the functions of controlling the display screen to self-luminous, display images, etc. Optionally, in this embodiment, the application processor can send a frame rate adjustment instruction to the display driver chip through the Mobile Industry Processor Interface (MIPI), and the display driver chip can adjust the frame rate of the display screen based on the frame rate adjustment instruction, and adjust the frame rate of the display screen to a determined target frame rate. Exemplarily, if the frame rate adjustment instruction is a frequency hopping instruction, the display driver chip will adjust the frame rate of the display screen by frequency hopping; if the frame rate adjustment instruction is an instruction to first hop and then change frequency, the display driver chip can adjust the frame rate of the display screen by first hopping and then changing frequency.

[0049] In the above-mentioned display screen frequency conversion method, since the target frame rate corresponding to the display screen of the electronic device is determined according to the operating parameters of the electronic device, and the operating parameters of the electronic device change slowly at adjacent moments, the difference between the determined target frame rate and the initial frame rate of the display screen will not be too large, and the granularity of the change will be finer, so that a frame rate adjustment instruction can be generated according to the determined target frame rate and the initial frame rate of the display screen, and the frame rate adjustment instruction is sent to the display driver chip to instruct the display driver chip to adjust the frame rate of the display screen. By fine-tuning the frame rate of the display screen, the switching of the display screen frame rate is smoother, and while balancing the load of the electronic device central processor and the frame rate of the display screen, it will not bring a large experience gap to the user.

[0050] In this embodiment, the process of generating a frame rate adjustment instruction according to the target frame rate and the initial frame rate of the display screen is explained in detail. In one embodiment, the above S202 includes:

[0051] Step A: generating a frame rate adjustment instruction according to the type of the target frame rate and the type of the initial frame rate.

[0052] The type of the target frame rate refers to whether the target frame rate is a basic frame rate of the display screen or a frequency hopping frame rate. Similarly, the type of the initial frame rate refers to whether the initial frame rate is a basic frame rate of the display screen or a frequency hopping frame rate.

[0053] Taking the basic frame rate of the display screen as 120Hz as an example, assuming that the display screen supports 3-frequency division, the variable basic frame rate of the display screen can be 120Hz, 90Hz, 72Hz, 60Hz, 51Hz, 40Hz...; assuming that the display screen supports 6-frequency division, the variable basic frame rate of the display screen can be 120Hz, 113Hz, 90Hz, 80Hz, 72Hz, 65Hz, 60Hz, 55Hz, 51Hz, 45Hz, 40Hz...

[0054] Optionally, in this embodiment, the application processor can first determine the variable basic frame rate of the display screen based on the division number supported by the display screen, and then determine whether the initial frame rate is a variable basic frame rate based on the value of the initial frame rate of the display screen, thereby determining the type of the initial frame rate; similarly, the application processor can determine whether the target frame rate is a variable basic frame rate based on the value of the target frame rate, thereby determining the type of the target frame rate.

[0055] Optionally, in this embodiment, the application processor may generate a frame rate adjustment instruction including the following three situations. The following will explain the detailed process of the application processor generating a frame rate adjustment instruction according to the type of the target frame rate and the type of the initial frame rate.

[0056] The first type: if the initial frame rate is the basic frame rate of the display screen, a first frequency hopping instruction is generated; the first frequency hopping instruction is used to instruct the display driver chip to adjust the frame rate of the display screen by frequency hopping.

[0057] In this embodiment, if the initial frame rate is the basic frame rate of the display screen, then when adjusting the frame rate of the display screen, if it is directly adjusted to the next basic frame rate, the frame rate change difference of the display screen is large, and it can be adjusted to the frequency hopping frame rate of the display screen first. In this scenario, the application processor can generate a first frequency hopping instruction, and instruct the display driver chip to adjust the frame rate of the display screen by frequency hopping through the first frequency hopping instruction. For example, Figure 2 As shown, Figure 2 The frame rate in the left column is the basic frame rate of the display. Figure 2 The frame rate in the middle right column is the frequency hopping frame rate of the display. Assuming that the initial frame rate of the display is 120Hz and the target frame rate is 116Hz, the application processor can generate a first frequency hopping instruction to instruct the display driver chip to adjust the frame rate of the display from 120Hz to 116Hz by frequency hopping. It can be understood that compared with the adjustment from 120Hz to 90Hz in traditional technology, the adjustment process of adjusting the frame rate of the display from 120Hz to 116Hz makes the granularity of the display frame rate change higher and the frame rate change smoother. It is a fine-tuning of the frame rate of the display, which will not cause a huge change in the picture of the display and affect the user experience.

[0058] The second type: if the initial frame rate is the frequency hopping frame rate of the display screen and the target frame rate is the frequency hopping frame rate of the display screen, a second frequency hopping instruction is generated; the second frequency hopping instruction is used to instruct the display driver chip to adjust the frame rate of the display screen by frequency hopping.

[0059] In this embodiment, if the initial frame rate of the display screen is the frequency hopping frame rate of the display screen, and the target frame rate is also the frequency hopping frame rate of the display screen, then the frame rate of the display screen can be adjusted by frequency hopping. In this scenario, the application processor can generate a second frequency hopping instruction, and instruct the display driver chip to adjust the frame rate of the display screen by frequency hopping through the second frequency hopping instruction. For example, Figure 3 As shown, Figure 3 The frame rate in the left column is the basic frame rate of the display. Figure 3 The frame rates in the middle column and the right column are the frequency hopping frame rates of the display. Assuming that the initial frame rate of the display is 116Hz and the determined target frame rate is 110Hz, the application processor can generate a second frequency hopping instruction to instruct the display driver chip to adjust the frame rate of the display from 116Hz to 110Hz by frequency hopping. It should be noted that Figure 2 and Figure 3 The frame rate in the figure is just an example. The frequency can be divided more finely based on the frequency division number supported by the display.

[0060] The third type: if the initial frame rate is the frequency hopping frame rate of the display screen and the target frame rate is the basic frame rate of the display screen, a frequency conversion instruction is generated; the frequency conversion instruction is used to instruct the display driver chip to adjust the frame rate of the display screen by frequency hopping and frequency conversion.

[0061] In this embodiment, if the initial frame rate of the display screen is the frequency hopping frame rate of the display screen, and the target frame rate is the basic frame rate of the display screen, then the frame rate of the display screen can be adjusted to the basic frame rate corresponding to the initial frame rate by frequency hopping, and then the frame rate of the display screen can be adjusted to the target frame rate by frequency conversion. In this scenario, the application processor can generate a frequency conversion instruction, and through the frequency conversion instruction, instruct the display driver chip to adjust the frame rate of the display screen by frequency hopping and frequency conversion. For example, please continue to refer to Figure 2 , assuming that the initial frame rate of the display is 116Hz, the determined target frame rate is 90Hz, the initial frame rate is the frequency hopping frame rate of the display, and the target frame rate is the variable frequency frame rate of the display. In this scenario, the application processor can generate a frequency conversion instruction to instruct the display driver chip to adjust the frame rate of the display from 116Hz to 90Hz by frequency hopping and frequency conversion.

[0062] It should be noted that, in the present embodiment, when the frame rate of the display screen is adjusted by frequency hopping, the frequency hopping method is a common frequency hopping method in the prior art. Optionally, the frequency hopping instruction sent by the application processor to the display driver chip may be to instruct the display driver chip to adjust the internal clock crystal oscillator and adjust all timing signals of the display driver chip to adjust the frame rate of the display screen. It may also be to instruct the display driver chip to adjust the number of rows of the front and rear corridors to adjust the frame rate of the display screen. The present embodiment does not limit the specific implementation method of frequency hopping.

[0063] In this embodiment, the process of generating frame rate adjustment instructions by the application processor according to the type of target frame rate and initial frame rate of the display screen is relatively simple and requires less calculation, thereby ensuring the efficiency of generating frame rate adjustment instructions. The application processor can determine the target frame rate according to the operating parameters of the electronic device, and then generate frame rate adjustment instructions in a timely manner to adjust the frame rate of the display screen in a timely manner, thereby ensuring a balance between the load of the electronic device and the frame rate of the display screen. At the same time, the determined target frame rate will not cause large fluctuations in the picture of the electronic device, thereby minimizing the impact on user experience.

[0064] In some scenarios, after the frame rate of the display screen is adjusted by frequency hopping, light compensation can also be performed on the display screen to reduce the impact of frequency hopping on the optical characteristics of the display screen. Based on the above embodiment, in one embodiment, the above method also includes:

[0065] Step B: sending a compensation instruction to the display driver chip; the compensation instruction is used to instruct the display driver chip to perform light compensation on the display screen when frequency hopping is performed.

[0066] Optionally, in this embodiment, the compensation instruction may be sent by the application processor at the same time as the frequency hopping instruction is sent to the display driver chip, or the application processor may first send the frequency hopping instruction to the display driver chip and then send the compensation instruction to the display driver chip. In addition, it should be noted that in the embodiment of the present application, the frequency conversion instruction sent by the application processor to the display driver chip is used to instruct the display driver chip to adjust the frame rate of the display screen by frequency hopping and frequency conversion. Therefore, when the application processor sends the frequency conversion instruction to the display driver chip, it may also send the compensation instruction to the display driver chip to instruct the display driver chip to perform light compensation on the display screen when performing frequency hopping.

[0067] Optionally, in this embodiment, after the application processor sends a compensation instruction to the display driver chip, it can instruct the display driver chip through the compensation instruction to modify the data remapping function of the display driver chip when frequency hopping, so as to fine-tune the display brightness and display chromaticity of the display screen and maintain the brightness of the display picture at the brightness corresponding to the basic frame rate of the display screen.

[0068] In this embodiment, the application processor sends a compensation instruction to the display driver chip, which can instruct the display driver chip to perform light compensation on the display screen when frequency hopping is performed, so as to compensate for the impact of frequency hopping on the brightness of the display screen, thereby ensuring that the brightness of the display screen is not affected while adjusting the frame rate of the display screen.

[0069] In the above scenario of determining the target frame rate corresponding to the operating parameters according to the operating parameters of the electronic device, the target frame rate corresponding to the operating parameters can be determined according to the operating parameters and a preset correspondence table. Based on the above embodiment, in one embodiment, the above S201 includes: determining the target frame rate according to the operating parameters and a preset correspondence table; the preset correspondence table includes the correspondence between the operating parameters and the frame rate; the operating parameters include the temperature of the electronic device.

[0070] The operating parameters of the electronic device may include the temperature and load of the electronic device. Preferably, in this embodiment, the operating parameters of the electronic device may be the temperature of the electronic device, that is, in this embodiment, the preset correspondence table may include the correspondence between the temperature of the electronic device and the frame rate of the display screen. For example, the correspondence between the temperature of the electronic device and the frame rate of the display screen can be seen in Figure 4 The corresponding relationship shown in the example.

[0071] Optionally, in this embodiment, the temperature of the electronic device can be measured in real time, and then the target frame rate corresponding to the real-time temperature of the electronic device can be determined based on the real-time temperature of the electronic device and a preset correspondence table, and the frame rate of the display screen can be adjusted based on the target frame rate corresponding to the real-time temperature of the electronic device.

[0072] In the present embodiment, the process of determining the target frame rate of the display screen according to the operating parameters of the electronic device and the preset correspondence table is relatively simple, and the efficiency of determining the target frame rate can be ensured; in addition, since the preset correspondence table includes the correspondence between the operating parameters of the electronic device and the frame rate of the display screen, the target frame rate determined in this way corresponds to the operating parameters of the electronic device, so that the determined target frame rate is more in line with the actual operating conditions of the electronic device, thereby avoiding large adjustments when adjusting the frame rate of the display screen, making the switching of the frame rate of the display screen smoother, thereby reducing the impact of the switching of the display screen frame rate on the user experience.

[0073] In one embodiment, Figure 5 As shown, a display frequency conversion method is provided. This embodiment takes the method applied to a display driver chip of an electronic device as an example. In this embodiment, the method includes the following steps:

[0074] S301, receiving a frame rate adjustment instruction sent by an application processor; the frame rate adjustment instruction is generated by the application processor according to the target frame rate and the initial frame rate of the display screen of the electronic device based on the operating parameters of the electronic device.

[0075] The operating parameters of the electronic device may include the temperature of the electronic device and / or the load of the electronic device, etc. The temperature change of the electronic device may be caused by the load change of the central processing unit (CPU) of the electronic device during operation, for example, the CPU is overloaded or the load is reduced, etc., or it may be caused by the change of the temperature of the environment in which the electronic device is located. Optionally, the load of the electronic device may be related to the number of applications running on the electronic device, or it may be related to the frame rate of the applications running on the electronic device.

[0076] In an embodiment of the present application, the frame rate of the display screen of the electronic device is the number of times the display screen refreshes the image per second, in Hz. Among them, the smoothness of the screen display is related to the frame rate of the display screen, and the higher the frame rate, the higher the smoothness of the screen display. Optionally, the display screen in the embodiment of the present application can be a display screen that supports N-frequency division, wherein N is a positive integer, and the variable frame rate of the display screen = the base frequency frame rate of the display screen * N / (N+M), M≥0, M is an integer, and taking the basic frame rate of the display screen as 120Hz as an example, assuming that the display screen supports 3-frequency division, the variable frame rate of the display screen can be 120Hz, 90Hz, 72Hz, 60Hz, 51Hz, 40Hz...

[0077] Optionally, in this embodiment, the change information of the operating parameters can be determined according to the operating parameters of the electronic device, and then the target frame rate corresponding to the display screen of the electronic device can be determined based on the change information of the operating parameters. Taking the operating parameters including temperature as an example, it can be determined whether the temperature of the electronic device is increased or decreased according to the temperature of the electronic device. If it is determined that the temperature of the electronic device is increased, the initial frame rate of the display screen of the electronic device can be reduced to determine the target frame rate. If it is determined that the temperature of the electronic device is decreased, the initial frame rate of the display screen of the electronic device can be increased to determine the target frame rate. It can be understood that if the operating parameters of the electronic device include load, the target frame rate corresponding to the display screen of the electronic device can also be determined based on this principle. It can be understood that in this embodiment, the finer the granularity of the operating parameters of the electronic device, the finer the granularity of the determined target frame rate, so that the display screen of the electronic device can perform smoother frame rate switching.

[0078] It should be noted that the target frame rate determined in this embodiment is the frame rate supported by the display screen of the electronic device. Optionally, the determined target frame rate can be the baseband frame rate of the display screen or the high-precision variable frequency frame rate of the display screen. This embodiment does not limit the type of the determined target frame rate.

[0079] Optionally, in this embodiment, the application processor may determine how to adjust the initial frame rate of the display screen to the target frame rate based on the difference between the target frame rate and the initial frame rate of the display screen, and then generate a frame rate adjustment instruction based on the determined adjustment method. Exemplarily, if the difference between the target frame rate and the initial frame rate is less than a preset threshold, the application processor may determine to adjust the initial frame rate to the target frame rate by frequency hopping, and the generated frame rate adjustment instruction may be a frequency hopping instruction; if the difference between the target frame rate and the initial frame rate is greater than the preset threshold, the application processor may determine to adjust the initial frame rate to the target frame rate by frequency hopping first and then by frequency conversion, and the generated frame rate adjustment instruction may be an adjustment instruction that first indicates frequency hopping and then indicates frequency conversion. As another optional implementation, in this embodiment, the application processor can first determine the variable basic frame rate of the display screen according to the frequency division number supported by the display screen, and then determine whether the initial frame rate is a variable basic frame rate according to the value of the initial frame rate of the display screen, thereby determining the type of the initial frame rate; similarly, the application processor can determine whether the target frame rate is a variable basic frame rate according to the value of the target frame rate, thereby determining the type of the target frame rate, and generating a frame rate adjustment instruction according to the type of the initial frame rate and the type of the target frame rate. Optionally, in this embodiment, the application processor may generate a frame rate adjustment instruction including the following three situations, and the detailed process of the application processor generating a frame rate adjustment instruction according to the type of the target frame rate and the type of the initial frame rate will be explained below.

[0080] The first type: if the initial frame rate is the basic frame rate of the display screen, a first frequency hopping instruction is generated; the first frequency hopping instruction is used to instruct the display driver chip to adjust the frame rate of the display screen by frequency hopping.

[0081] The second type: if the initial frame rate is the frequency hopping frame rate of the display screen and the target frame rate is the frequency hopping frame rate of the display screen, a second frequency hopping instruction is generated; the second frequency hopping instruction is used to instruct the display driver chip to adjust the frame rate of the display screen by frequency hopping.

[0082] The third type: if the initial frame rate is the frequency hopping frame rate of the display screen and the target frame rate is the basic frame rate of the display screen, a frequency conversion instruction is generated; the frequency conversion instruction is used to instruct the display driver chip to adjust the frame rate of the display screen by frequency hopping and frequency conversion.

[0083] For a detailed description of the above three situations in which the application processor generates a frame rate adjustment instruction, please refer to the above description of the application processor side, which will not be repeated here in this embodiment.

[0084] Optionally, in this embodiment, the display driver chip may receive a frame rate adjustment instruction sent by the application processor through a mobile industry processor interface (Mobile Industry Processor Interface, MIPI).

[0085] S302, adjusting the frame rate of the display screen according to the frame rate adjustment instruction.

[0086] Optionally, in this embodiment, the display driver chip can adjust the frame rate of the display screen according to the type of the frame rate adjustment instruction. For example, if the frame rate adjustment instruction is a frequency hopping instruction, the display driver chip will adjust the frame rate of the display screen by frequency hopping; if the frame rate adjustment instruction is an instruction of frequency hopping first and then frequency conversion, the display driver chip can adjust the frame rate of the display screen by frequency hopping first and then frequency conversion.

[0087] Optionally, in this embodiment, if the frame rate adjustment instruction is a frequency hopping instruction, the display driver chip can adjust the frame rate of the display screen to the target frame rate by frequency hopping; if the frame rate adjustment instruction is a frequency conversion instruction, the display driver chip can first adjust the initial frame rate to a basic frame rate corresponding to the initial frame rate by frequency hopping, and then convert the frequency from the basic frame rate corresponding to the initial frame rate to the target frame rate by frequency conversion.

[0088] In addition, it should be noted that, in this embodiment, the display driver chip can also receive the compensation instruction sent by the application processor, and perform light compensation on the display screen based on the compensation instruction when the frame rate of the display screen is adjusted by frequency hopping. Optionally, in this embodiment, the display driver chip can fine-tune the display brightness and display chromaticity of the display screen by modifying the data remapping function of the display driver chip when frequency hopping is performed, so as to maintain the brightness of the display screen at the brightness corresponding to the basic frame rate of the display screen.

[0089] In the above-mentioned display screen frequency conversion method, since the target frame rate corresponding to the display screen of the electronic device is determined according to the operating parameters of the electronic device, and the operating parameters of the electronic device change slowly at adjacent moments, the difference between the determined target frame rate and the initial frame rate of the display screen will not be too large, and the granularity of the change will be finer. The frame rate adjustment instruction received by the display driver chip is generated by the application processor according to the determined target frame rate and the initial frame rate of the display screen. In this way, the display driver chip can adjust the frame rate of the display screen based on the received frame rate adjustment instruction, and make the switching of the display screen frame rate smoother by fine-tuning the frame rate of the display screen. While balancing the load of the central processor of the electronic device and the frame rate of the display screen, it will not bring a large experience gap to the user.
