[0025] The following will be combined with the accompanying drawings of the embodiments of the present application to clearly describe the technical solutions of the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0026] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0027] In order to better explain the embodiments of the present application, Figure 1 Explain the working process of the screen display:

[0028] like Figure 1 As shown in FIG, the system on chip (SOC) is responsible for processing image data and transmits the processed image data to the memory on the screen through the MIPI DSI interface.

[0029] The screen includes a high-frequency TE oscillator and RAM memory. The high-frequency TE oscillator generates a sync signal called TE (Timing Enable), which triggers the screen driver circuit to start operating. The RAM memory stores image data and periodically reads image data and sends it to the screen driver circuit.

[0030] The screen driver circuit generates electrical signals that drive the screen based on the image data read from the RAM and the received TE synchronization signal. These electrical signals are transmitted to the display module, causing the screen to display the image.

[0031] Therefore, the SoC is responsible for image processing and transferring the image data to the screen RAM via the MIPI DSI interface. Then, the high-frequency TE oscillator inside the screen generates a synchronization signal. The driver circuit sends the correct electrical signal to the screen panel based on the image data and synchronization signal in the RAM, ultimately displaying the image on the screen.

[0032] To solve the problems in the related art, the embodiment of the present application provides a working parameter adjustment method, device, electronic equipment and readable storage medium, which can solve the problem that the current local refresh technical solution cannot achieve the purpose of power saving in the related art.

[0033] The working parameter adjustment method provided by the embodiment of the present application will be described in detail in combination with the drawings, specific embodiments and application scenarios.

[0034] Figure 2 A flowchart of the working parameter adjustment method provided by the embodiment of the present application.

[0035] As shown in the figure, the working parameter adjustment method can include steps 210-230, and the method is applied to a working parameter adjustment device, as follows: Figure 2

[0036] Step 210, in the case of local refresh, determining N first local areas corresponding to the local refresh, wherein N is a positive integer;

[0037] As shown in the figure, the N first local areas include a first local area 310, a first local area 320 and a first local area 330. Figure 3

[0038] Determining the N first local areas corresponding to the local refresh facilitates subsequent targeted local refresh of the N first local areas, and adjusting the working parameters of the associated module according to the N first local areas to achieve the purpose of power saving.

[0039] Step 220, determining a first working parameter value according to the N first local areas, wherein the first working parameter value includes a first frequency value and a first voltage value.

[0040] The first frequency value is the refresh frequency or working frequency of the electronic equipment when processing the local area. The higher the frequency value, the more times it processes in a unit of time, and the faster the processing speed.

[0041] The first voltage value is the voltage level required by the electronic equipment when processing the local area. The higher the voltage value, the higher the processing capacity and the faster the response speed that the device can provide.

[0042] For each local area, its size is calculated, and the first working parameter value is dynamically adjusted according to the size of the first local area, which can more effectively allocate resources. Larger local areas will obtain higher frequency and voltage, thereby improving processing efficiency.

[0043] In step 220, the following steps can be included:

[0044] ​​In a case where the frame rate of the local refresh is greater than the preset frame rate, a local refresh scheduling coefficient value is determined according to the N first local areas.

[0045] The preset frame rate can be 3 frames, 5 frames, or 8 frames.

[0046] For example, when the local refresh continues to trigger, in a case where the frame rate of the local refresh is greater than 5 frames, the dynamic adjustment state is automatically entered, and a local refresh scheduling coefficient value is determined according to the N first local areas.

[0047] Therefore, in a case where the frame rate of the local refresh is greater than the preset frame rate, a local refresh scheduling coefficient value is determined according to the N first local areas, so that a first working parameter value is determined according to the local refresh scheduling coefficient value, which can avoid frequent fluctuations of the working parameters of the associated module and ensure the working stability of the associated module.

[0048] In a possible embodiment, step 220 can specifically include the following steps:

[0049] In step 221, a local refresh scheduling coefficient value is determined according to the N first local areas, and the local refresh scheduling coefficient value is proportional to the area size of the N first local areas.

[0050] In step 222, a first working parameter value is determined according to the local refresh scheduling coefficient value, and the local refresh scheduling coefficient value is proportional to the first working parameter value.

[0051] The local refresh scheduling coefficient value is a coefficient for scheduling local area refresh, which is used to control the resource allocation of the device when processing the local area and reflects the importance and processing priority of the local area.

[0052] The first working parameter value is a parameter value for controlling the device or working state, such as refresh frequency, processing speed, etc., which directly affects the working efficiency and performance of the device or.

[0053] Regarding step 221: The larger the size of the local area, the more resources are generally needed for processing or refreshing. Therefore, the local refresh scheduling coefficient value is proportional to the size of the local area. The size of each local area is calculated, and then a corresponding scheduling coefficient value is assigned according to the size. The larger the size, the higher the scheduling coefficient value, and the first working parameter value is determined according to the local refresh scheduling coefficient value.

[0054] Regarding step 222: The higher the local refresh scheduling coefficient value, the more resources and higher processing priority are needed for the local area. Therefore, the first working parameter value should also be increased accordingly. The first working parameter value is adjusted according to the size of the local refresh scheduling coefficient value. The higher the scheduling coefficient value, the higher the first working parameter value.

[0055] Thus, by dynamically adjusting the scheduling coefficient value and the working parameter value according to the size of the local area, resources can be allocated more effectively. Larger local areas will obtain more resources, thereby improving processing efficiency. Larger local areas usually require higher processing priority, and by adjusting the working parameter value, it can be ensured that these areas are processed in time, avoiding delays or errors due to insufficient resources. Dynamic adjustment of resource allocation and working parameters according to changes in local areas enhances the adaptability and flexibility of the system, and can maintain efficient operation in different scenarios.

[0056] In one possible embodiment, step 221 can specifically include the following steps:

[0057] According to the N first local areas, the interval size between two adjacent first local areas, the area size of each first local area, and the refresh rate of each first local area are determined to obtain N-1 interval sizes, N area sizes, and N refresh rates; and the resolution of the display screen is determined.

[0058] According to the N-1 interval sizes, the N area sizes, the N refresh rates, and the resolution of the display screen, a local refresh scheduling coefficient value is determined.

[0059] The local refresh scheduling coefficient value needs to consider the following factors:

[0060] The size of the local area, the larger the area, the higher the local refresh scheduling coefficient value should be to ensure that it obtains sufficient computing resources for high-quality refresh.

[0061] The refresh rate of the local area, the higher the refresh rate of the area, the higher the local refresh scheduling coefficient value should be to ensure that these rapidly changing areas can be updated in time.

[0062] The interval size between adjacent areas, the larger the interval between adjacent areas, the more computing resources need to be allocated to these areas individually, so the local refresh scheduling coefficient value will also be relatively higher.

[0063] The resolution of the overall display screen, the higher the screen resolution, the number of local areas will also increase accordingly, which will affect the overall coefficient allocation.

[0064] After considering these factors, an accurate local refresh scheduling coefficient value can be determined, which will directly determine the computing resources and working parameters obtained by each local area subsequently.

[0065] Therefore, by accurate local area identification and parameter setting, the refresh quality of important areas can be maximized, global information such as screen resolution is fully utilized, more intelligent and optimized local refresh scheduling is realized, and power saving effect can be improved.

[0066] The local refresh scheduling coefficient value is determined according to the N-1 interval sizes, the N region sizes, the N refresh rates, and the resolution of the display screen.

[0067] For each first local area, a local refresh parameter value is determined according to the interval size, the region size, and the refresh rate of the first local area, to obtain N local refresh parameter values; the interval size of the first local area is the size of the interval between the first local area and the adjacent local area in a preset direction.

[0068] The local refresh scheduling coefficient value is determined according to the N local refresh parameter values and the resolution of the display screen.

[0069] Interval size: the distance or interval between the first local area and the adjacent local area in a preset direction. The interval size affects the independence and mutual influence of the local areas. For example, in the calculation of the second local area, the interval size of the second local area is the interval size between the first local area and the second local area; in the calculation of the third local area, the interval size of the third local area is the interval size between the second local area and the third local area.

[0070] Region size: the size of the first local area itself. The larger the region size, the more resources are needed for processing or refreshing.

[0071] Refresh rate: the number of times the local area is refreshed per unit time. The higher the refresh rate, the faster the frequency of local area update and the faster the processing speed.

[0072] Local refresh parameter value: used to describe the refresh demand and resource allocation of the local area.

[0073] The determination of the local refresh parameter value needs to consider the interval size, the region size, and the refresh rate of the local area. The interval size affects the independence and mutual influence of the local areas, the region size affects the resource demand, and the refresh rate affects the processing speed.

[0074] For each first local area, the interval size between it and the adjacent local area in a preset direction is calculated. For each first local area, the size of itself is calculated; according to the characteristics of the local area or the system demand, the refresh rate of each first local area is determined.

[0075] Comprehensively calculate the local refresh parameter value: Based on the interval size, area size and refresh rate, comprehensively calculate the local refresh parameter value of each first local area. The smaller the interval size, the larger the area size, and the higher the refresh rate, the larger the local refresh parameter value.

[0076] According to the N first local areas, the area size of each first local area and the refresh rate of each first local area can be determined. As shown in formula (1):

[0077]

[0078] Among them, (1+k n )*h n *f n , is the local refresh parameter value;

[0079] n: refers to the total number of local refresh areas, n = 1, 2, 3…, n, which indicates the number of local refresh areas;

[0080] C: refers to the total number of lines corresponding to the screen resolution. Taking an electronic device with a resolution of 1080x2400 as an example, C = 2400;

[0081] k n : represents the distribution coefficient of the nth local refresh area, which is the quotient of the interval size and the resolution;

[0082] When n=1, k=0;

[0083] When n>1, k n =(Row-start n -Row-end n-1 -1) / C,Row-start n Refers to the first row position of the nth local brush area, Row-end n-1 Refers to the tail position of the n-1th local brush area;

[0084] h n : Indicates the number of local refresh rows in the nth local refresh area;

[0085] f n : Indicates the refresh rate of the nth local refresh area. 60 represents a 60FPS refresh rate.

[0086] like Figure 3 As shown, the first local area 310 has an area size of 100 lines and a refresh rate of 1 FPS;

[0087] The first local area 320 has an area size of 1200 lines and a refresh rate of 60 FPS;

[0088] The first local area 330 has an area size of 200 rows and a refresh rate of 30 FPS.

[0089] Specifically, the first local area corresponds to the local area information shown in Table 1. Figure 3

[0090] Table 1

[0091]

[0092] With the detailed local area information, the final local refresh scheduling coefficient value can be determined according to the data.

[0093] The local refresh scheduling coefficient value is determined according to the N local refresh parameter values and the resolution of the display screen, including:

[0094] The sum of the N local refresh parameter values is determined.

[0095] The quotient of the sum of the N local refresh parameter values and the resolution of the display screen is calculated.

[0096] The local refresh scheduling coefficient value is determined according to the quotient of the sum of the N local refresh parameter values and the resolution of the display screen.

[0097] As shown in Table 1, 100+720 30+700 2.5 = 79132.5, i.e. the sum of the N local refresh parameter values is 79132.5;

[0098] As shown in formula (1), 79132.5 ÷ 2400 ÷ 60 = 54.95%, i.e. the local refresh scheduling coefficient value is 54.95%.

[0099] In one possible embodiment, step 222 can specifically include the following steps:

[0100] The local refresh coefficient value associated local refresh coefficient interval is determined.

[0101] According to the mapping relationship set, the first working parameter value associated with the local refresh coefficient interval is determined; the mapping relationship set includes multiple sets of mapping relationship between local refresh coefficient intervals and working parameter values.

[0102] According to the local refresh scheduling coefficient value calculated in the foregoing, the specific interval range to which it belongs is determined. The range of the entire local refresh scheduling coefficient value can be divided into multiple different intervals, and each interval represents the size of the required computing resources.

[0103] A mapping relationship set needs to be established in advance, which includes the mapping relationship between multiple sets of local refresh coefficient intervals and corresponding working parameter values. As shown in Table 2: ​

[0104] Table 2

[0105] Local refresh coefficient interval CPU frequency CPU voltage GPU frequency GPU voltage 75％-100％ 3.0G 0.8V 734 Mhz 0.63V 50％-75％ 2.5G 0.7V 607 Mhz 0.58V 25％-50％ 1.5G 0.6V 389 Mhz 0.53V 0％-25％ 1.0G 0.5V 160 Mhz 0.48V Local refresh coefficient interval DPU frequency DPU voltage DDR frequency DDR voltage 75％-100％ 514 Mhz 0.73V 2.7G 1.08V 50％-75％ 375 Mhz 0.68V 1.7G 1.03V 25％-50％ 325 Mhz 0.63V 768 Mhz 0.98V 0％-25％ 200 Mhz 0.57V 547 Mhz 0.94V

[0106] Exemplarily, the local refresh scheduling coefficient value is 54.95%, the local refresh coefficient value is associated with a local refresh coefficient interval of 50%-75%, and according to the mapping relationship set, a first working parameter value associated with the local refresh coefficient interval of 50%-75% is determined. The first working parameter value includes: CPU frequency of 2.5G, CPU voltage of 0.7V, GPU frequency of 607Mhz, GPU voltage of 0.58V, DPU frequency of 375Mhz, DPU voltage of 0.68V, DDR frequency of 1.7G, and DDR voltage of 1.03V.

[0107] Based on the mapping relationship set, the corresponding first working parameter value can be directly found according to the previously determined local refresh coefficient interval, and dynamic mapping of the local refresh coefficient value to the specific working parameter value can be realized.

[0108] Therefore, the division of the local refresh coefficient interval and the setting of the working parameter value corresponding to each interval can be flexibly adjusted according to actual needs. According to the mapping relationship set, the first working parameter value associated with the local refresh coefficient interval can be determined, and the corresponding computing resources and performance parameters can be accurately allocated. Therefore, the advantages of local refresh can be fully utilized, and more intelligent and efficient power saving technology can be realized.

[0109] In step 230, the working parameters of the associated module are adjusted to the first working parameter value, and the associated module includes at least one of the following: CPU, GPU, DPU, DDR, and DDIC.

[0110] The associated module is a related hardware and software module responsible for driving and updating the local area.

[0111] The associated module will be described below:

[0112] The central processing unit (CPU) is the core processing unit of the computer, responsible for executing calculation and control instructions.

[0113] The graphics processing unit (GPU) is a processor specially used for processing graphics and image data, suitable for high-concurrency computing tasks.

[0114] The data processing unit (DPU) is a processor that focuses on efficient data processing, commonly used to accelerate data-intensive applications.

[0115] Double Data Rate Synchronous Dynamic Random-Access Memory (DDR), a type of memory that can transmit data on both the rising and falling edges of each clock cycle, increasing the data transfer rate.

[0116] Display Driver Integrated Circuit (DDIC), a circuit specifically designed to control displays, responsible for converting image data into display signals.

[0117] The working parameters include working frequency and working voltage, which will be explained separately as follows:

[0118] Working frequency refers to the number of instructions executed by the associated module per second, usually measured in Hertz (Hz). Higher working frequency means the processor can perform more calculations per second, providing higher performance. Common working frequencies for associated modules range from a few hundred megahertz (MHz) to several gigahertz (GHz).

[0119] Working voltage refers to the voltage supplied to the associated module, usually measured in volts (V). The size of the working voltage directly affects the power consumption and heat generation of the associated module.

[0120] Working frequency and working voltage are two key indicators of the performance and power consumption of the associated module. Higher working frequency means higher performance and higher power consumption. Higher voltage means higher power consumption and heat generation, and performance will also increase accordingly.

[0121] Therefore, by adjusting the working parameters of the associated module to the first working parameter value, the dynamic adjustment of the working parameters of the associated module is realized, which can be reasonably configured and adjusted according to specific needs, effectively balancing performance and power consumption.

[0122] In one possible embodiment, after step 230, the following steps can also be included:

[0123] In the case of local refresh, determine the M second local areas corresponding to the local refresh, where M is a positive integer;

[0124] In the case where the positions and sizes of the M second local areas and the N first local areas are consistent, the working parameters of the associated module are kept at the first working parameter value to update the local image of the M second local areas;

[0125] In the case that the positions and sizes of the M second local areas and the N first local areas are inconsistent, a second working parameter value is determined according to the M second local areas, the second working parameter value including a second frequency value and a second voltage value.

[0126] Second local area: A new local area that needs to be updated during the local refresh process. Compared with the first local area, the second local area can have different positions and sizes.

[0127] Second working parameter value: The working parameter value required when refreshing the second local area, including a second frequency value and a second voltage value, used to control the resource allocation and processing speed of the electronic device when processing the second local area.

[0128] Second frequency value: The refresh frequency or working frequency of the electronic device when processing the second local area. The higher the frequency value, the more times it is processed per unit time, and the faster the processing speed.

[0129] Second voltage value: The voltage level required by the electronic device when processing the second local area. The higher the voltage value, the higher the processing capability and faster response speed the device can provide.

[0130] During the local refresh process, it is necessary to determine which local areas need to be updated. These areas are referred to as second local areas. M is a positive integer representing the number of local areas that need to be updated.

[0131] If the positions and sizes of the second local areas are completely consistent with those of the first local areas, it means that the refresh requirement has not changed, so the first working parameter value can be used to update the local image. If the positions and sizes are consistent, the working parameters of the associated module are kept as the first working parameter value. If the positions and sizes of the second local areas are inconsistent with those of the first local areas, it means that the refresh requirement has changed, and the working parameter value needs to be re-determined.

[0132] By dynamically adjusting the working parameter value, resources can be allocated more accurately. If the second local areas are consistent with the first local areas, the first working parameter value can be continued to be used to avoid resource waste. If the positions and sizes are inconsistent, resources are re-allocated according to the new requirements. By dynamically adjusting the working parameter value, the processing priority can be determined more accurately. For example, local areas with inconsistent positions and sizes may require higher frequency and voltage to ensure timely updating. The ability to dynamically adjust the working parameter value according to the specific circumstances of the local area enhances adaptability and flexibility, enabling efficient operation in different scenarios.

[0133] In the subsequent partial refresh process, when the second partial region and the first partial region have the same size and position, the working parameters of the associated module are kept at the first working parameter value. Since the second partial region and the first partial region are completely consistent in position and size, the previously determined first working parameter value can be directly reused, i.e., there is no need to recalculate and assign new working parameters for the second partial region, but the previous parameter settings are retained.

[0134] In this way, without recalculating and assigning working parameters, the previous parameter settings can be directly reused, ensuring the update quality while reducing the consumption of computing resources, thereby improving the update efficiency.

[0135] In a possible embodiment, in the case of non-partial refresh, the working parameters of the associated module are adjusted to a third working parameter value, which is the working parameter value corresponding to full-screen refresh.

[0136] Non-partial refresh: the need to refresh the entire screen or entire region, rather than only refreshing the partial region. Non-partial refresh usually involves a larger amount of data and higher resource requirements.

[0137] Third working parameter value: the working parameter value required by the system or device in the case of non-partial refresh. These parameter values are used to control resource allocation and processing speed during full-screen refresh.

[0138] Full-screen refresh: refreshing the entire screen or entire region, usually involving updating all pixels or data points. Full-screen refresh usually requires higher frequency and voltage to ensure timely updating of all regions.

[0139] In the case of non-partial refresh, the entire screen or entire region needs to be refreshed, so higher frequency and voltage are required to ensure timely updating of all regions. The third working parameter value is the working parameter value corresponding to full-screen refresh. The working parameters of the associated module are adjusted to the third working parameter value. The third working parameter value usually includes higher frequency and voltage values to meet the requirements of full-screen refresh. Using the adjusted third working parameter value, the entire screen or entire region is refreshed.

[0140] In the case of non-partial refresh, that is, when there is no partial refresh condition triggered, the entire screen needs to be refreshed. The third working parameter value is the corresponding working parameter determined for the full-screen refresh scenario, which is different from the first working parameter value. The third working parameter value is determined according to the requirements of full-screen refresh, and the third working parameter value needs to be able to meet the performance and power consumption requirements of full-screen refresh, which is usually higher than the first working parameter value of partial refresh.

[0141] By dynamically adjusting the working parameter value, resources can be allocated more accurately. In the case of non-local refresh, the system can provide sufficient frequency and voltage according to the demand of full-screen refresh, ensuring that all areas can be updated in time. By dynamically adjusting the working parameter value according to the refresh demand, the adaptability and flexibility of the system are enhanced, and efficient operation can be maintained in different scenarios.

[0142] Thus, the working parameter configuration of the associated module can be flexibly switched according to different refresh scenarios, improving adaptability. In the full-screen refresh scenario, the second working parameter value optimized for this scenario is used to ensure refresh quality.

[0143] In the embodiments of the present application, in the case of local refresh, it is necessary to determine which local areas need to be refreshed.
