FIG. 2 is a flowchart illustrating a method for adjusting a screen refresh rate according to an embodiment. As shown in fig. 2, the method for adjusting the screen refresh rate includes steps 202 to 206.
It can be understood that, the power saving mode of the electronic device can make the electronic device save more power, and prolong the service time of the battery power. In the power saving mode, the electronic device may turn off and disable certain functions, such as turning off the navigation function, turning off the bluetooth function, turning off the vibration function, etc.; the electronic device can also close some applications running in the background; the electronic device may also reduce the refresh rate of the screen, etc.
In one embodiment, an opening instruction of the power saving mode is received in a display interface of the power saving mode, and the power saving mode is entered.
As shown in fig. 3a, in the display interface of the power saving mode, 302 is a power saving mode control, and when a user clicks a switch in the power saving mode control 302, that is, the electronic device receives an opening instruction of the power saving mode, the electronic device enters the power saving mode. In the power saving mode, the user may click 304 the exit control to exit the power saving mode.
In another embodiment, a power level of an electronic device is detected; when the electric quantity is smaller than the electric quantity threshold value, generating a power-saving mode popup window, and displaying the power-saving mode popup window in a display interface of a screen; and receiving an opening instruction in the popup window of the power saving mode, and entering the power saving mode.
As shown in fig. 3b, when the power amount is less than the power amount threshold, a power saving mode popup 306 is generated and displayed in a display interface of the screen to prompt the current low power amount and suggest the user to start the power saving mode; when a user clicks the opening button, namely the electronic equipment receives an opening instruction in the power saving mode popup window, the electronic equipment enters the power saving mode. In the power saving mode, the user may click 304 the exit control to exit the power saving mode.
In another embodiment, receiving voice, and analyzing the voice to obtain an analysis result; and entering a power saving mode when the analysis result contains a power saving mode starting instruction.
As shown in fig. 3c, the voice is received and analyzed to obtain an analysis result 308, and a power saving mode opening instruction "help me open the power saving mode" exists in the analysis result 308, and the device enters the power saving mode. In the power saving mode, the user may click 304 the exit control to exit the power saving mode.
In another embodiment, the temperature of the electronic device is detected, and the electronic device is controlled to enter the power saving mode when the temperature of the electronic device is higher than a temperature threshold. It is understood that various components of the electronic device, such as a Central Processing Unit (CPU), a battery, and various circuits, generate heat during operation, so that the temperature of the electronic device is increased. However, the temperature of the electronic device is too high, and each component inside the electronic device is easily burned out.
Therefore, when the temperature of the electronic equipment is higher than the temperature threshold value, the temperature of the electronic equipment is over-high, the electronic equipment is controlled to enter the power saving mode, resources of the electronic equipment can be saved, the temperature of the electronic equipment can be reduced, and safety of each component in the electronic equipment is guaranteed.
The refresh rate refers to the number of times the electron beam repeatedly scans the image on the screen. The higher the refresh rate, the better the image (picture) stability displayed by the screen. For example, the screen refresh rate may be 60HZ, 120 HZ; while an image picture displayed at a screen refresh rate of 120HZ is more stable than an image picture displayed at a screen refresh rate of 60 HZ.
It is understood that, in order to make the screen invisible to the human eye, the refresh rate of the screen needs to be greater than or equal to the lower limit value; in order to make the battery power of the electronic device usable for a longer time, the refresh rate of the screen needs to be less than or equal to the upper limit value, and the range from the upper limit value to the lower limit value, i.e., the refresh rate range of the screen. Wherein the upper and lower limit values may be empirical values.
If the first refresh rate is within the refresh rate range of the screen, the screen can be ensured to be in a normal use state when the refresh rate of the screen of the electronic equipment is adjusted to the first refresh rate; and the first refresh rate is smaller than the refresh rate threshold, so that the maximum value of the first refresh rate is limited, and the screen power consumption can be saved. The first refresh rate may also be a specific gear, such as one of 60Hz, 90Hz, 120Hz, 144Hz, etc.
Wherein the refresh rate threshold may be one of the values in a sub-range between the lower limit value and the median value of the refresh rate range. Where the median refers to the value centered in the middle of a set of data in order. For example, if the refresh rate range is [60,120], then the lower limit of the refresh rate range is 60, the median is 90, and then the refresh rate threshold may be one of the values in the sub-range [60,90], e.g., 60,70,85, etc.
In one embodiment, the first refresh rate may be a lower limit value of a refresh rate range of the screen, i.e., a minimum value in the refresh rate range, and the screen power may be saved to the maximum extent.
The refresh rate threshold may be set as desired by the user. Further, the electronic device obtains a refresh rate before entering the power saving mode, and sets a refresh rate threshold smaller than the refresh rate before entering the power saving mode. After the electronic equipment enters the power saving mode, the refresh rate of the screen of the electronic equipment is adjusted to be a first refresh rate, the first refresh rate is smaller than a refresh rate threshold value, the refresh rate threshold value is smaller than the refresh rate before the electronic equipment enters the power saving mode, and then the first refresh rate after the electronic equipment enters the power saving mode is smaller than the refresh rate before the electronic equipment enters the power saving mode, so that the refresh rate of the screen is reduced, and the power consumption of the screen is saved.
The current system state refers to a state in which the current system of the electronic device is located. The current system state may be one of a game state, a video play state, an application switching state, an animation play state, a running designated application state, a social chat state, a music play state, and the like.
The current system state may be a system state with a high requirement on the screen refresh rate, such as one of a game state, a video playing state, an application switching state, an animation playing state, or a state of running a specified application; or may be a system state with low requirements on the screen refresh rate, such as a social chat state, a music playing state, or the like. The current system states are different, and the corresponding screen refresh rate requirements may be different.
In one embodiment, the electronic device detects the current system state by at least one of a polling read mechanism and a registration callback listening.
In another embodiment, the electronic device detects an application program in the current screen display interface and each element in the screen display interface, and determines the current system state based on the application program in the current screen display interface and each element in the screen display interface.
The application currently in the screen display interface refers to the application currently in the screen display interface. If the user uses the WeChat, the WeChat is an application program in the current screen display interface; when the user uses the WeChat and simultaneously uses the lyric floating window function of the music application program to display the lyrics of the song in the screen display interface, the WeChat and the music application program are both the application programs in the current screen display interface.
The number of the application programs in the current screen display interface can be one or more. The currently used application program may be an application program of the electronic device, such as a camera, music, an album, and the like, and may also include an application program downloaded by the user, such as WeChat, Paibao, and the like.
The elements in the screen display interface can include pictures, videos, audios and texts, and also can include the brightness of the screen, the size of the screen and the like.
For example, if the application currently used by the electronic device is WeChat and the screen display interface includes a video, it may be determined that the current system state is a video playing state. For another example, if the application currently used by the electronic device is a game, and the screen display interface includes a game element defense tower, an enemy soldier, and the like, it may be determined that the current system state is a game state. For another example, if the application currently used by the electronic device includes WeChat, the WeChat is running at the front end, and each element in the screen display interface includes text and pictures, it may be determined that the current system state is the social chat state.
And step 206, determining a target refresh rate based on the current system state, and adjusting the refresh rate of the screen from the first refresh rate to the target refresh rate.
If the current system states are different, the corresponding screen refresh rate requirements may be different, and the target refresh rate determined based on the current system states may also be different.
For example, if the current system state is a system state with a high requirement on the screen refresh rate, such as a game state, a video playing state, an application switching state, an animation playing state, or a state in which a specified application is run, the determined target refresh rate may be higher; when the current system state is a system state with a low requirement on the screen refresh rate, such as a social chat state, a music playing state, or the like, the determined target refresh rate may be lower.
The electronic equipment presets the corresponding relation between each system state and the refresh rate and acquires the corresponding relation between the system states and the refresh rate; matching the corresponding relation between the system state and the refresh rate with the current system state, determining the refresh rate of the current system state from the corresponding relation between the system state and the refresh rate, and taking the determined refresh rate as the target refresh rate.
For example, when the current system state is the game state, it is determined from the correspondence between the system state and the refresh rate that the refresh rate of the game state is 90HZ, that is, the target refresh rate is 90 HZ; when the current system state is the music playing state, it is determined from the correspondence between the system state and the refresh rate that the refresh rate of the music playing state is 60HZ, that is, the target refresh rate is 60 HZ.
According to the method for adjusting the screen refresh rate, when the electronic equipment enters the power saving mode, the refresh rate of the screen of the electronic equipment is adjusted to the first refresh rate, so that the power consumption of the screen of the electronic equipment can be reduced firstly, and the electric quantity of the electronic equipment is saved; the current system state is detected, the target refresh rate is determined based on the current system state, and the refresh rate of the screen can be adjusted from the first refresh rate to the target refresh rate, so that the refresh rate of the screen is matched with the current system state, and the accuracy of the adjusted screen refresh rate is improved.
Further, according to the method for adjusting the screen refresh rate, when the electronic device enters the power saving mode, power consumption can be optimized, that is, power consumption of the screen of the electronic device is reduced, the target refresh rate is determined based on the current system state, and then the refresh rate of the screen is adjusted from the first refresh rate to the target refresh rate, so that the display effect and the user experience of the screen display interface in the current system state can be ensured, and balance between power consumption and experience is achieved.
In one embodiment, after adjusting the refresh rate of the screen from the first refresh rate to the target refresh rate, the method further includes: when the electronic equipment exits the power saving mode, acquiring a second refresh rate; the second refresh rate is higher than or equal to the first refresh rate; the refresh rate of the screen is adjusted from the target refresh rate to a second refresh rate.
And when the electronic equipment exits the power saving mode, the electronic equipment is restored to the normal mode, in order to ensure that the screen display interface is clearer, smoother and more accurate, the obtained second refresh rate is higher than or equal to the first refresh rate, and then the refresh rate of the screen is adjusted to the second refresh rate from the target refresh rate.
Further, before the electronic device enters the power saving mode, the method further includes: acquiring the current original refresh rate of a screen; when the electronic device exits the power saving mode, obtaining a second refresh rate, comprising: when the electronic equipment exits the power saving mode, acquiring an original refresh rate; adjusting the refresh rate of the screen from the target refresh rate to a second refresh rate, comprising: and restoring the refresh rate of the screen from the target refresh rate to the original refresh rate.
Before the electronic device enters the power saving mode, the current original refresh rate of the screen, that is, the refresh rate of the screen in the normal mode of the electronic device, is obtained, and the refresh rate is stored in a storage medium (such as a flash memory) of the electronic device. When the electronic equipment exits the power saving mode, the original refresh rate is obtained from the storage medium, and the refresh rate of the screen is adjusted from the target refresh rate to the second refresh rate, namely the refresh rate of the screen is restored to the refresh rate before entering the power saving mode.
In another embodiment, as shown in fig. 4, when the electronic device receives a power saving mode on command, step 402 is executed to save the original refresh rate; step 404 is executed to enter a power saving mode; step 406 is executed to determine whether the current refresh rate is the lowest refresh rate; if yes, that is, the current refresh rate is the lowest refresh rate, then the refresh rate does not need to be adjusted, step 408; if not, executing step 410 to adjust the refresh rate to the lowest refresh rate; step 414 is executed to detect the current system state.
In one embodiment, after detecting the current system state, the method further comprises: acquiring the priority of the current system state; determining a target refresh rate based on a current system state, comprising: a target refresh rate is determined based on the priority of the current system state.
A higher priority of the current system state, indicating a higher level of importance of the current system state, may determine a higher target refresh rate. The priority of the current system state is proportional to the size of the target refresh rate.
The electronic equipment presets the corresponding relation between each system state and the priority, matches the corresponding relation between the system states and the priorities with the current system state, and determines the priority of the current system state from the corresponding relation between the system states and the priorities.
For example, when the current system state is the game state, if it is determined from the correspondence between the system state and the priority that the priority of the game state is 4, it is determined that the target refresh rate is 90 HZ; when the current system state is the music playing state, it is determined from the correspondence between the system state and the priority that the priority of the game state is 2, and the target refresh rate is determined to be 60 HZ.
In one embodiment, after detecting the current system state, the method further comprises: acquiring an application program running in the current system state; determining a target refresh rate based on a current system state, comprising: and determining a target refresh rate based on the category of the application program operated in the current system state.
And if the different application programs belong to different categories, the corresponding target refresh rate can be determined based on the categories of the different application programs. For example, the category to which the WeChat and the microblog belong is a social application program, and the target refresh rate corresponding to the social application program may be 60 HZ; the category to which the tremble and the fast hand belong is a short video application, and the target refresh rate corresponding to the short video application may be 90 HZ.
Further, the priority of the application program running in the current system state is obtained, and the target refresh rate is determined based on the priority of the application program running in the current system state. The higher the priority of the application, the higher the determined target refresh rate.
Further, when detecting that the specified refresh rate exists in the application program running in the current system state, taking the specified refresh rate as a target refresh rate, and adjusting the refresh rate of the screen from the first refresh rate to the specified refresh rate of the application program.
In one embodiment, the target refresh rate includes a first refresh rate, a second target refresh rate, and a third target refresh rate; determining a target refresh rate based on the category to which the application program running in the current system state belongs, wherein the determining comprises the following steps: when the class of the application program running in the current system state is a video class, determining a first target refresh rate; when the class to which the application program running in the current system state belongs is a social class, determining a second target refresh rate; when the class to which the application program running in the current system state belongs is other than the video class and the social class, determining a third target refresh rate; the first target refresh rate, the second target refresh rate, and the third target refresh rate are sequentially decreased.
Applications for video categories such as trembling, fast-hand, Tik Tok, etc. Social category applications such as WeChat, microblog, QQ, twitter, etc. Other categories besides video categories and social categories may include game categories, sports categories, office categories, financial categories, and the like.
When the class of the application program running in the current system state is the video class, the video is played in the application program, and the requirement of the video on the refresh rate of the screen of the electronic equipment is high, so that the determined first refresh rate is high, and the video can be clearly and accurately played by the application program of the video class in the running process.
When the category to which the application program running in the current system state belongs is the social category, the user communicates with other users by adopting the application program, and the requirement on the refresh rate of the screen of the electronic equipment is moderate during communication.
When the class to which the application program running in the current system state belongs is other than the video class and the social class, the requirement of the application program running in the current system state on the refresh rate of the screen is low, a lower third target refresh rate can be determined, and the power consumption of the screen is saved.
It is understood that, if the requirements of the application programs of the video category, the application programs of the social category, and the application programs of other categories except the video category and the social category on the refresh rate of the screen of the electronic device are sequentially reduced, the first target refresh rate, the second target refresh rate, and the third target refresh rate are also sequentially reduced.
In one embodiment, the method further comprises: counting the use duration of each application program in a historical time period; acquiring the use duration of an application program running in the current system state in a historical time period; determining a target refresh rate based on the category to which the application program running in the current system state belongs, wherein the determining comprises the following steps: and determining a target refresh rate based on the category of the application program running in the current system state and the usage time length in the historical time period.
The historical time period can be set according to the needs of the user, such as one month before the current time, 5 days before the current time, and the like.
After the electronic equipment acquires the application program operated in the current system state, acquiring the use duration of the application program operated in the current system state in a historical time period. The usage duration refers to a duration of using the application. The service life is long, which indicates that the application program is a common application program for users; the usage time is long, which means that the application is an application that is not commonly used by the user.
When the category of the application program running in the current system state is fixed, the use duration of the application program in the historical time period is in positive correlation with the target refresh rate.
When the category of the application program running in the current system state is fixed, the longer the use time of the application program in the historical time period is, the more the application program is the application program frequently used by the user, and the higher the importance degree of the application program is, so that a larger target refresh rate can be determined, and the page content of the application program can be displayed more clearly and accurately when the application program is running in the current system state.
When the category of the application program running in the current system state is fixed, the shorter the usage time of the application program in the historical time period is, the less frequently used application program is indicated, and the lower the importance degree of the application program is, so that the smaller target refresh rate can be determined, and the power consumption of the screen of the electronic equipment can be saved when the application program is running in the current system state.
In one embodiment, after the electronic device enters the power saving mode, the electric quantity of the electronic device is detected in real time; and when the electric quantity of the electronic equipment reaches the electric quantity threshold value, detecting that the currently running application program comprises the target application program, and exiting the power saving mode. Wherein, the target application refers to an application program interacting with a user.
When the electric quantity of the electronic equipment reaches the electric quantity threshold value, the electric quantity of the electronic equipment is more, normal use and operation of the electronic equipment can be guaranteed, and when the currently-operated application program is detected to comprise the target application program, namely the current electronic equipment interacts with a user, the content of a display interface in a screen is important, and the power saving mode can be quitted. After exiting the power saving mode, the refresh rate of the electronic device is increased, the functions are increased, and the electronic device can interact with the user more accurately.
In one embodiment, the current system state comprises a first system state or a second system state, the refresh rate requirement of the first system state being higher than the refresh rate requirement of the second system state; determining a target refresh rate based on a current system state, and adjusting a refresh rate of a screen from a first refresh rate to the target refresh rate, including: when the current system state is a first system state, acquiring a first reference refresh rate corresponding to the first system state, and adjusting the refresh rate of the screen from the first refresh rate to the first reference refresh rate; when the current system state is a second system state, acquiring a second reference refresh rate corresponding to the second system state, and adjusting the refresh rate of the screen from the first refresh rate to the second reference refresh rate; the first reference refresh rate is higher than the second reference refresh rate.
The first system state is one of a game state, a video playing state, an application program switching state, an animation playing state or a state of running a specified application program; the second system state is a social chat state or a music playing state. The designated application program may be an application program that needs a high refresh rate and is set by a user, such as a microblog, a wechat, or the like, or an application program that supports a high refresh rate. When the appointed application program is operated, the page of the appointed application program is displayed on the display interface of the screen, the screen is refreshed by adopting the first reference refresh rate, and the clearer page of the appointed application program can be obtained. The first system state has a high demand on visual effect, and the second system state has a low demand on visual effect, i.e. the refresh rate demand of the first system state is higher than the refresh rate demand of the second system state.
When the current system state is a first system state, the screen refresh rate corresponding to the first system state is a first reference refresh rate; and when the current system state is a second system state, the screen refresh rate corresponding to the second system state is a second reference refresh rate. The first reference refresh rate is higher than the second reference refresh rate because the refresh rate requirement of the first system state is higher than the refresh rate requirement of the second system state.
In this embodiment, the current system state includes a first system state or a second system state, when the current system state is the first system state, a corresponding first reference refresh rate is obtained, when the current system state is the second system state, a corresponding second reference refresh rate is obtained, and if the refresh rate requirement of the first system state is higher than the refresh rate requirement of the second system state, the first reference refresh rate is higher than the second reference refresh rate, so that the screen refresh rate can be adjusted more accurately.
In one embodiment, when the first system state is a video playing state, acquiring a first reference refresh rate corresponding to the first system state, and adjusting the refresh rate of the screen from the first refresh rate to the first reference refresh rate includes: the method comprises the steps of obtaining a video frame rate corresponding to a video playing state, taking the video frame rate as a first reference refresh rate, and adjusting the refresh rate of a screen from the first refresh rate to the first reference refresh rate.
Frame rate is the frequency (rate) at which images appear continuously on the display in units of frames. When the electronic equipment plays the video in the screen, the frame rate of the video is consistent with the refresh rate of the screen.
Therefore, when the video is in the video playing state in the first system state, the frame rate of the video corresponding to the video playing state is acquired, the frame rate of the video is used as the first reference refresh rate, and the refresh rate of the screen is adjusted from the first refresh rate to the first reference refresh rate, so that the frame rate of the video is consistent with the refresh rate of the screen, and the normal playing of the video can be ensured.
In one embodiment, when the first system state is the application program switching state, acquiring a first reference refresh rate corresponding to the first system state, and adjusting the refresh rate of the screen from the first refresh rate to the first reference refresh rate includes: acquiring a first reference refresh rate corresponding to the switching state of the application program, and adjusting the refresh rate of the screen from the first refresh rate to the first reference refresh rate; the method further comprises the following steps: and after the application program switching is completed, adjusting the refresh rate of the screen from the first reference refresh rate to the first refresh rate.
And the application program switching state is the state of the application program used in the current interface when switching. For example, the application program used in the current interface is a, and the electronic device switches the application program used in the current interface from a to B when receiving a start instruction of the application program B. If the application program is not used in the current interface, and the electronic device receives a start instruction of the application program C, the application program C is started, and the current interface is switched to the application program C. The state of the application program A when switched to the application program B and the state of the application program C when switched to the application program C from no application program are both the application program switching states.
It can be understood that, when the current system state of the electronic device is the application switching state, if the refresh rate of the screen is low, the user may think that the switching application is wrong and restart the application, which wastes time and reduces the efficiency of switching the application.
Therefore, when the current system state of the electronic device is the application switching state, the current interface in the screen of the electronic device switches the application, and the requirement on the refresh rate of the screen is high, that is, the first reference refresh rate corresponding to the application switching state is high, so that the application can be accurately switched.
In one embodiment, as shown in FIG. 5, the electronic device performs step 502 to obtain an original refresh rate before entering the power saving mode. The electronic device executes step 504 to determine whether the electronic device is in a low power state, and if so, executes step 522 to adjust the refresh rate to the lowest refresh rate; when the determination is no, step 506 is performed. The low battery state is a state where the battery is below a battery threshold.
Executing step 510, determining whether the current system state is a game state (further, a high frame rate game state), and if yes, executing step 524, adjusting the refresh rate to the original refresh rate; when the determination is no, step 514 is performed.
In one embodiment, the method further comprises: obtaining the brightness of the environment; determining a target refresh rate based on a current system state, and adjusting a refresh rate of a screen from a first refresh rate to the target refresh rate, including: acquiring a reference refresh rate corresponding to the current system state; and adjusting the reference refresh rate based on the ambient light brightness to obtain a target refresh rate, and adjusting the refresh rate of the screen from the first refresh rate to the target refresh rate.
Ambient light brightness refers to the brightness of the environment in which the electronic device is located. The reference refresh rate refers to a refresh rate corresponding to the current system state. If the current system states are different, the corresponding screen refresh rate requirements may be different, and the reference refresh rates corresponding to the current system states may also be different.
The electronic equipment firstly obtains a reference refresh rate corresponding to the current system state, and then adjusts the reference refresh rate based on the ambient light brightness to obtain a target refresh rate. For example, the electronic device first obtains a reference refresh rate a corresponding to the current system state, and when the ambient light brightness is high in the daytime, the reference refresh rate can be increased to obtain a target refresh rate; and at night, namely when the ambient light brightness is low, the reference refresh rate can be reduced to obtain the target refresh rate.
In this embodiment, a reference refresh rate corresponding to the current system state is obtained, the reference refresh rate is adjusted based on the ambient light brightness to obtain a target refresh rate, and the refresh rate of the screen is adjusted to the target refresh rate, so that the accuracy of the adjusted refresh rate can be improved.
In one embodiment, the current system state comprises a first system state or a second system state, the refresh rate requirement of the first system state being higher than the refresh rate requirement of the second system state; obtaining a reference refresh rate corresponding to a current system state, including: when the current system state is a first system state, acquiring a first reference refresh rate corresponding to the first system state; when the current system state is a second system state, acquiring a second reference refresh rate corresponding to the second system state; adjusting the reference refresh rate based on the ambient light brightness to obtain a target refresh rate, and adjusting the refresh rate of the screen from the first refresh rate to the target refresh rate, including: when the current system state is a first system state, adjusting a first reference refresh rate based on the ambient light brightness to obtain a target refresh rate, and adjusting the refresh rate of the screen from the first refresh rate to the target refresh rate; and when the current system state is a second system state, adjusting a second reference refresh rate based on the ambient light brightness to obtain a target refresh rate, and adjusting the refresh rate of the screen from the first refresh rate to the target refresh rate.
The first system state is one of a game state, a video playing state, an application program switching state animation playing state or a running appointed application program state; the second system state is a social chat state or a music playing state. The first system state has a high demand on visual effect, and the second system state has a low demand on visual effect, i.e. the refresh rate demand of the first system state is higher than the refresh rate demand of the second system state.
When the current system state is a first system state, the screen refresh rate corresponding to the first system state is a first reference refresh rate; and when the current system state is a second system state, the screen refresh rate corresponding to the second system state is a second reference refresh rate. The first reference refresh rate is higher than the second reference refresh rate because the refresh rate requirement of the first system state is higher than the refresh rate requirement of the second system state.
In this embodiment, the current system state includes a first system state or a second system state, and when the current system state is the first system state, a corresponding first reference refresh rate is obtained, and then the first reference refresh rate is adjusted based on the ambient light brightness to obtain a target refresh rate; when the current system state is a second system state, acquiring a corresponding second reference refresh rate, and adjusting the second reference refresh rate based on the ambient light brightness to obtain a target refresh rate; and finally, adjusting the refresh rate of the screen to the target refresh rate, so that the accuracy of the adjusted refresh rate can be improved.
In one embodiment, adjusting the reference refresh rate based on the ambient light level to obtain the target refresh rate comprises: when the ambient light brightness is lower than the ambient light brightness threshold value, reducing the reference refresh rate to obtain a target refresh rate; and when the ambient light brightness is higher than or equal to the ambient light brightness threshold value, increasing the reference refresh rate to obtain the target refresh rate.
When the ambient light brightness is lower than the ambient light brightness threshold (such as at night), the ambient light brightness is low, human eyes are sensitive to the screen brightness of the electronic equipment, and the reference refresh rate can be reduced to obtain the target refresh rate, so that the screen power consumption of the electronic equipment is saved.
When the ambient light brightness is higher than or equal to the ambient light brightness threshold (such as daytime), the ambient light brightness is high, human eyes are insensitive to the screen brightness of the electronic equipment, and the content in the screen display interface is not easy to see clearly, so that the reference refresh rate can be increased to obtain the target refresh rate, the quality of the display content in the screen display interface is improved, and the content in the display interface is displayed more clearly and more accurately.
