All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this application belong to the protection scope of this application.

It should be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application can be practiced in sequences other than those illustrated or described herein, and that references to "first," "second," etc. distinguish Objects are generally of one type, and the number of objects is not limited. For example, there may be one or more first objects. In addition, "and/or" in the specification and claims means at least one of the connected objects, and the character "/" generally means that the related objects are an "or" relationship.

The method for adjusting the refresh rate of the display screen provided by the embodiment of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

FIG. 1 is a schematic flowchart of a method for adjusting the refresh rate of a display screen provided by an embodiment of the present application. The method for adjusting the refresh rate of the display screen may include the following steps:

Step 101 , acquire visual influencing factors associated with the display screen of the electronic device, the visual influencing factors include at least one of brightness values of screen pixels, current light environment parameters of the environment where the electronic device is located, user characteristic information and application program type.

Generally speaking, the impact of the display screen of an electronic device on the user's vision is usually related to factors such as the content displayed on the display screen, the environment in which the electronic device is located, the user's own physical fitness and/or behavioral habits, and the duration of using the electronic device. The visual impact factors may indicate those factors related to the visual impact of the display on the user. For example, the visual influencing factors may include at least one of brightness values of screen pixels, current light environment parameters of the environment where the electronic device is located, user characteristic information, and application program types.

In other words, the visual impact factor can be any one of the brightness value of the screen pixel, the current light environment parameters of the environment where the electronic device is located, user characteristic information and application program type, and the visual impact factor can also include any of the above four any combination between. In this way, the target refresh frequency can be determined by considering the influence of four factors, the brightness value of the screen pixels, the current light environment parameters of the environment where the electronic device is located, the user characteristic information and the application program type, which effectively ensures the adjustment of the refresh rate of the display screen. Frequency accuracy and comprehensiveness.

In step 101, when the display screen of the electronic device is working, that is, the display screen of the electronic device is not in a screen-off state, but is displaying some content, the visual influencing factors associated with the display screen of the electronic device may be acquired.

Step 102, adjusting the refresh rate of the display screen to a target refresh rate matching the visual impact factor according to the visual impact factor.

The refresh rate of the display screen may also be referred to as the drive frequency of the display screen, which is used to reflect the number of times the screen of the display screen is refreshed per second. In step 102, the preset refresh frequency adjustment rule can be determined according to the visual influence factor, and then the target refresh frequency matching the visual influence factor can be determined according to the preset refresh frequency adjustment rule, and then the refresh frequency of the display screen can be adjusted to Adjust to target refresh rate. The preset refresh rate adjustment rule may refer to a rule that when the display screen has less impact on the user's eyes, the target refresh rate is lower, and when the screen screen has a greater impact on the user's eyes, the target refresh rate is higher. . In this way, when the display screen has a greater impact on the user's eyes, the refresh rate of the display screen can be increased to give priority to meeting the needs of reducing the user's visual fatigue. Reduce the user's visual fatigue, so the refresh rate of the display screen can be reduced to meet the needs of electronic devices to save power consumption, so as to dynamically adjust the refresh rate of the display screen, and more flexibly balance the needs of reducing visual fatigue and power consumption of electronic devices Purpose.

It can be understood that if the visual influencing factor is the brightness value of the screen pixel, the lower the brightness value of the screen pixel, such as the black background part, the smaller the impact on the user's human eyes, and the lower the target refresh rate at this time; on the contrary, The higher the brightness value of the screen pixel, the greater its impact on the user's human eyes, and the higher the target refresh rate at this time.

If the visual influencing factor is the current light environment parameter of the environment where the electronic device is located, when the current light environment parameter of the environment where the electronic device is located is more irritating to the user's human eyes, the impact of the display screen on the user's human eye is smaller. On the contrary, when the current light environment parameters of the environment where the electronic device is located are less stimulating to the user's human eyes, the impact of the display screen on the user's human eyes is increased, and the target refresh frequency is higher at this time.

If the visual influencing factor is user feature information, the user feature information may include user age, frequency of use of electronic devices by the user, and the like. Different user groups can be divided according to the user characteristic information, and the degree of influence of the display screen on the human eyes of different user groups can be used to determine the corresponding target refresh frequency. In other words, different target refresh frequencies may be adopted according to different user groups.

If the visual influencing factor is the type of application, different target refresh frequencies may be adopted according to different applications. For example, for applications with a long single use time such as video playback type and e-book type, a higher target refresh rate can be used; for applications with a short single use time such as dialing and text messages, a lower target refresh rate can be used. The target refresh rate.

For example, taking visual factors including the brightness value of screen pixels as an example, the preset refresh rate rule can be embodied as a preset correspondence between multiple preset brightness values and refresh rates, for example, brightness value L1 corresponds to refresh rate F1, and brightness value L2 corresponds to the refresh frequency F2, and the brightness value L3 corresponds to the refresh frequency F3... Among them, the number of screen pixels is usually multiple, and the brightness value of each screen pixel may be different according to the content displayed on the screen. Based on this, in some examples, the average brightness value of the screen pixels can be calculated according to the brightness values corresponding to each screen pixel, and then the average brightness value can be matched with multiple preset brightness values, so that the average brightness value is matched to brightness If the value is L1, the refresh frequency F1 can be determined as the target refresh frequency. In other words, the refresh frequency of the display screen can be adjusted to the refresh frequency F1 at this time.

In the embodiment of the present application, the method for adjusting the refresh rate of the display screen can obtain the visual influence factors associated with the display screen of the electronic device. At least one of feature information and application type; according to the visual impact factor, adjust the refresh rate of the display screen to a target refresh rate matching the visual impact factor. In this way, the refresh rate of the display screen can be dynamically adjusted through visual influence factors, avoiding the high power consumption of electronic equipment caused by the fixed refresh rate being too high, or the visual fatigue of the user caused by the fixed refresh rate being too low. Depending on the situation, the dynamic target refresh rate can more flexibly balance the needs of reducing visual fatigue and reducing power consumption of electronic equipment.

In some embodiments, when the visual influencing factor includes the brightness value of the screen pixel, the above step 102 may include the following steps:

According to the brightness value of the screen pixel, the area of the display screen is divided into N brightness sub-regions, the brightness value of the screen pixel in each brightness sub-region is within the same preset brightness value interval, and N is a positive integer;

According to the preset brightness value intervals where the brightness values of the screen pixels in each brightness sub-region are located, and the preset corresponding relationship between the brightness value range and the refresh frequency, determine the N sub-target refresh frequencies corresponding to the N brightness sub-regions one-to-one;

Adjust the refresh frequency of the first brightness sub-region to the first sub-target refresh frequency, the first brightness sub-region is any brightness sub-region in the N brightness sub-regions, and the first sub-target refresh frequency is one of the N sub-target refresh frequencies The sub-target refresh rate corresponding to the first brightness sub-region.

In this embodiment, the visual influencing factor may include the brightness value of the screen pixel, and the area of the display screen may be divided according to the brightness value of the screen pixel. Taking an image whose display content is 8bit as an example, the brightness value of the screen pixel The value range can be 0~255, and according to the preset division rules, the screen pixels can be divided into multiple preset brightnesses according to their brightness values of 0~L ₁ , L ₁ ~L ₂ , L ₂ ~L ₃ ...etc. value range, so as to classify and divide the regions to obtain N brightness sub-regions. It can be understood that the brightness values of the screen pixels in each brightness sub-region are all within the same preset brightness value range.

N sub-target refresh frequencies corresponding to N brightness sub-regions one-to-one can be determined according to the preset brightness value intervals in which the brightness values of the screen pixels in each brightness sub-region are located, and the preset correspondence between the brightness value intervals and the refresh frequency . For example, the brightness sub-area whose brightness value of the screen pixel is in the interval of 0- _L1 may correspond to the refresh frequency F1; the brightness sub-area of the screen pixel whose brightness value is in the interval _L1 - _L2 may correspond to the refresh frequency F2; the screen pixel The luminance sub-area whose luminance value is in the interval L ₂ ~ L ₃ can correspond to the refresh frequency F3... Among them, the value range of the refresh frequency F can be 1HZ ~ 10000HZ, and the specific value can be selected according to the actual situation, which is not specified here. Specific limits. For example, L ₁ can be 50, F1 can be 200HZ; L ₂ can be 100, F1 can be 1000HZ; L ₃ can be 150, F1 can be 1440HZ...

According to the preset luminance value intervals of the luminance values of the screen pixels in each luminance sub-region, N sub-target refresh frequencies corresponding to N brightness sub-regions one-to-one can be determined, that is, the target refresh frequency can include N sub-target refresh frequencies, The refresh frequency of the display screen can be adjusted according to the N sub-target refresh frequencies. For example, the refresh frequency of the first brightness sub-region (any brightness sub-region in the N brightness sub-regions) may be adjusted to the first sub-target refresh frequency corresponding to the first brightness sub-region. In other words, different refresh rates may be applied to different brightness sub-regions of the display screen.

It can be understood that, when the display content of the display screen changes, brightness sub-regions of the display screen may be re-divided according to brightness values of screen pixels.

In this way, the area of the display screen can be identified and divided into different brightness sub-regions according to the brightness values of the screen pixels, and different sub-target refresh frequencies can be applied to different brightness sub-regions, thereby reducing visual fatigue and saving power consumption of electronic devices. balance.

In some embodiments, in the case that the visual influencing factors include the current light environment parameters of the environment where the electronic device is located, the above step 102 may include the following steps:

According to the current light environment parameter and the preset corresponding relationship between the light environment parameter and the refresh rate, the refresh rate of the display screen is adjusted to a target refresh rate matching the current light environment parameter.

In this embodiment, the visual influencing factors may include the current light environment parameters of the environment where the electronic device is located, an ambient light sensing module may be installed in the electronic device, and the ambient light sensing module may be used to detect and record the current light environment parameters around the electronic device . Wherein, the current light environment parameter may include at least one item of current ambient light brightness, current ambient light color temperature and current ambient light chromaticity value.

According to the current light environment parameters and the preset corresponding relationship between the light environment parameters and the refresh frequency, the target refresh frequency matching the current light environment parameters can be determined, and the refresh frequency of the display screen can be adjusted to the target refresh frequency. It can be understood that if the current light environment parameter indicates that the current ambient light is more irritating to the user's human eyes, and the display screen has less impact on the user's human eyes at this time, then a lower refresh rate can be applied to the display screen at this time; Conversely, if the current light environment parameters of the environment where the electronic device is located indicate that the current ambient light is less irritating to the user's eyes, and the impact of the display screen on the user's eyes is increased, then the display screen can use a higher light intensity at this time. Refresh frequency.

For example, when the current light environment parameter is below AL ₁ , the target refresh frequency can be determined as refresh frequency F1; when the current light environment parameter is between AL ₁ and AL ₂ , the target refresh frequency can be determined as refresh frequency F2; When the environmental parameter is between AL ₂ and AL ₃ , the target refresh frequency may be determined as refresh frequency F3 . . . . Wherein, the value range of F may be 1HZ˜10000HZ. The current light environment parameter AL may be the current ambient light brightness, the current ambient light color temperature, or the current ambient light chromaticity value, or a combination of any two of the three, or a combination of the three. Among them, the value range of the current ambient light brightness can be 0nit to 100000nit; the value of the current ambient light color temperature can be 1000K to 10000K; the current ambient light chromaticity value can be calculated according to the horseshoe-shaped chromaticity diagram shown in Figure 2. Divided, different chromaticity areas can correspond to different refresh rates.

It can be understood that the preset correspondence between the light environment parameters (at least one of the current ambient light brightness, the current ambient light color temperature and the current ambient light chromaticity value) and the refresh frequency can be preset according to actual needs and stored in the electronic The specific values of the equipment and its corresponding relationship are not specifically limited here. It can also be understood that when it is detected that the environment where the electronic device is located changes, the current light environment parameters of the environment where the electronic device is located may be reacquired, and the refresh frequency of the display screen may be readjusted based on the new current light environment parameters.

In this embodiment, by identifying the light environment parameters of the environment where the electronic device is located, the stimulation of the surrounding ambient light to the user's human eyes is judged, thereby inferring the influence of the display screen on the user's human eyes, and the Different target refresh rates are applied to achieve a balance between reducing visual fatigue and saving power consumption of electronic devices.

In some embodiments, the current light environment parameters of the environment where the electronic device is located include at least one of current ambient light brightness, current ambient light color temperature and current ambient light chromaticity value.

In this embodiment, if the current light environment parameter is the current ambient light brightness, the higher the current ambient light brightness, the greater the stimulation of the current environment to the human eye, which reduces the impact of the display screen on the human eye. When the display screen can use a lower refresh rate; on the contrary, the lower the current ambient light brightness, it can indicate that the current environment is less irritating to the human eye, but it will increase the impact of the display screen on the human eye. Apply a higher refresh rate.

If the current light environment parameter is the current ambient light color temperature, the higher the current ambient light color temperature, it can indicate that the current environment is a cooler color tone, which is more irritating to the human eye, which in turn reduces the impact of the display on the human eye. The screen can use a lower refresh rate; on the contrary, the lower the color temperature of the current ambient light, it can indicate that the current environment is a warm color, the less irritating to the human eye, but the impact of the display on the human eye is increased, and the display at this time The screen can apply a higher refresh rate.

If the current light environment parameter is the chromaticity value of the current ambient light, the chromaticity value is usually a two-dimensional coordinate expressed by the color coordinates (x, y), as shown in Figure 2, the chromaticity can be calculated according to the horseshoe-shaped chromaticity diagram. Region division (such as chroma region A, chroma region B, chroma region C and chroma region D). According to the target chromaticity region matched with the chromaticity value of the current ambient light, and then according to the preset corresponding relationship between the chromaticity region and the refresh frequency, the target refresh frequency matching the target chromaticity region can be determined, and the target refresh frequency can be used on the display. It can be understood that, in FIG. 2 , the ambient light in the chromaticity area A to the chromaticity area D gradually becomes warmer, so the refresh frequency corresponding to the chromaticity area A to the chromaticity area D increases gradually.

It can also be understood that the current light environment parameter may also include any combination of current ambient light brightness, current ambient light color temperature and current ambient light chromaticity value, which is not specifically limited this time.

In this embodiment, the stimulation of the current ambient light to the user's human eyes can be judged by considering the current ambient light brightness, the current ambient light color temperature and the current ambient light chromaticity value, so as to determine the impact of the display screen on the user's human eyes, and then can A more accurate target refresh rate is determined, which further ensures the accuracy of adjusting the refresh rate of the display screen.

In some embodiments, when the visual influencing factors include brightness values of screen pixels and current light environment parameters of the environment where the electronic device is located, the above step 102 may include the following steps:

Determine the average brightness value corresponding to the display screen according to the brightness value of the screen pixels;

According to the average brightness value and the current light environment parameter, the refresh rate of the display screen is adjusted to a target refresh rate matching the average brightness value and the current light environment parameter.

In this embodiment, the visual influencing factors may include brightness values of screen pixels and current light environment parameters of the environment where the electronic device is located. The average brightness value corresponding to the display screen can be determined according to the brightness value of the screen pixels. For example, the content displayed on the display screen can be regarded as an image, and the brightness of the pixels on the screen can be regarded as the brightness of the image pixels of the image, and the average brightness value corresponding to the display screen can be calculated by performing grayscale processing on the image , to obtain the grayscale value of each image pixel, and then calculate the ratio of the sum of the grayscale values of all image pixels to the number of all image pixels to obtain the average grayscale of the image, which can determine the corresponding average brightness of the display screen value. Taking an 8-bit display screen as an example, the average brightness value can range from 0 to 255.

The ambient light perception module in the electronic device can detect and record the current light environment parameters around the electronic device, and then adjust the refresh rate of the display screen to match the average brightness value and the current light environment parameters. parameter to match the target refresh rate.

For example, when the average brightness value is relatively dark, and the current light environment parameter indicates that the current ambient light is more irritating to the user's eyes, the first target refresh frequency can be applied to the display screen; when the average brightness value is relatively bright, and When the current light environment parameter indicates that the current ambient light is less irritating to the user's eyes, apply the second target refresh frequency to the display screen; the average brightness value may be brighter, and the current light environment parameter indicates that the current ambient light has a greater impact on the user's human eye. When the eye irritation is greater, or when the average brightness value is darker, and the current light environment parameter indicates that the current ambient light stimulates the user's eyes less, the third target refresh frequency is applied to the display screen. Wherein, the first target refresh frequency, the second target refresh frequency and the third target refresh frequency satisfy the following condition: first target refresh frequency<third target refresh frequency<second target refresh frequency.

It can be understood that the above example is only used as a specific example to describe an implementation manner of this embodiment, so as to facilitate understanding of the technical solution of this embodiment, and is not intended as a specific limitation on the implementation manner of this embodiment. For example, according to the value range of the average brightness value, and the value or area range of the current light environment parameter (at least one of the current ambient light brightness, the current ambient light color temperature and the current ambient light chromaticity value), the common Match the target refresh rate. For another example, the target weight factor corresponding to the refresh frequency can be determined according to the sum of the weight corresponding to the average brightness value and the weight corresponding to the current light environment parameter, and then according to the target weight factor and the preset corresponding relationship between the weight factor and the refresh frequency, A target refresh rate matching the target weighting factor is determined and applied to the display.

In this embodiment, the refresh rate of the display screen can be adjusted by combining the brightness values of different screen pixels and the light environment parameters of the environment where the electronic device is located, so as to further ensure the accuracy of the target refresh rate, thereby reducing visual fatigue and The balance of saving power consumption of electronic equipment.

In some embodiments, when the visual influencing factors include user feature information, the above step 101 may also include the following steps:

Obtain the face image of the target user;

Determining the target user feature information of the target user according to the face image;

The above step 102 may include the following steps:

Determining a target refresh frequency that matches the characteristic information of the target user;

Adjust the refresh rate of the display to the target refresh rate.

In this embodiment, the visual influencing factors may also include user feature information. A face image of a target user may be acquired, where the target user may refer to a user who is using the electronic device. After the face image is obtained, the target user feature information of the target user can be determined through recognition. Wherein, the characteristic information of the target user may include the age of the target user and/or the target frequency of using the electronic device by the target user. Determining the age of the target user may be to directly obtain the identity information of the target user stored in the electronic device to determine the age of the target user, or it may be to perform face recognition based on big data to infer the age of the target user. Determining the target frequency of use of the electronic device by the target user may be obtained by obtaining the daily use time of the electronic device by the target user within a period of time, and then the target frequency may be calculated according to the average time.

The corresponding target refresh frequency can be matched according to the characteristic information of the target user. For example, the younger the target user is, the higher the corresponding target refresh frequency is. Conversely, the older the target user is, the lower the corresponding target refresh frequency is. For another example, the higher the target user's target frequency of using electronic equipment, the higher the corresponding target refresh frequency; conversely, the lower the target user's target frequency of using electronic equipment, the lower the corresponding target refresh frequency.

In this embodiment, the refresh frequency of the display screen can be adjusted according to user characteristic information, and user groups corresponding to different user characteristic information apply different target refresh frequencies, so as to achieve a balance between reducing visual fatigue and saving power consumption of electronic devices.

In some embodiments, when the visual influencing factor includes the application type, the above step 101 may also include the following steps:

identifying the target application corresponding to the current display interface of the display screen;

Determining a target application type corresponding to the target application from a plurality of preset application types;

The above step 102 may include the following steps:

Determine a target refresh rate that matches the target application type;

Adjust the refresh rate of the display to the target refresh rate.

In this embodiment, the visual influencing factors may also include application program types. The target application corresponding to the current display interface of the display screen can be identified, and the target application type corresponding to the target application can be determined from multiple preset application types.

It is understandable that different types of application programs have different functions, and the corresponding duration of use of these application programs by users will also be different. For example, video playback type applications and reading type applications, users usually need to spend more time when using these applications. In other words, when the target application type of the target application is determined to be video playback type or reading type , it usually indicates that the user needs to look at the display for an extended period of time. Another example is communication-type applications (dial-up, text messages), system general-type applications (clock, calendar), and users usually only need to spend a short time to meet their needs when using these applications, in other words , when the target application program type of the target application is determined to be a communication type or a system general type, it may indicate that the user only needs to watch the display screen for a short time.

Based on the different types of applications corresponding to the different durations of users watching the display, the corresponding target refresh frequency can be matched according to the target application type. For example, when the target application type is determined to be a video playback type or a reading type, the corresponding target The higher the refresh frequency is, on the contrary, when the target application program type of the target application is determined to be the communication type or the general system type, the corresponding target refresh frequency is lower.

In this embodiment, the refresh rate of the display screen can be adjusted according to the application program type, and different target refresh rates are applied to the display interfaces corresponding to different application program types, so as to achieve a balance between reducing visual fatigue and saving power consumption of electronic devices.

The method for adjusting the refresh rate of a display screen provided in the embodiment of the present application may be executed by a device for adjusting the refresh rate of a display screen. In the embodiment of the present application, the method for adjusting the refresh rate of the display screen performed by the device for adjusting the refresh rate of the display screen is taken as an example to describe the device for adjusting the refresh rate of the display screen provided in the embodiment of the present application.

As shown in Figure 3, the refresh rate adjusting device 300 of the display screen may include:

At least one of feature information and application type; according to the visual impact factor, adjust the refresh rate of the display screen to a target refresh rate matching the visual impact factor. In this way, the refresh rate of the display screen can be dynamically adjusted through visual influence factors, avoiding the high power consumption of electronic equipment caused by the fixed refresh rate being too high, or the visual fatigue of the user caused by the fixed refresh rate being too low. Depending on the situation, the dynamic target refresh rate can more flexibly balance the needs of reducing visual fatigue and reducing power consumption of electronic equipment.

In some embodiments, in the case that the visual influencing factors include brightness values of screen pixels, the adjustment module 302 may be used to:

According to the brightness value of the screen pixel, the area of the display screen is divided into N brightness sub-regions, the brightness value of the screen pixel in each brightness sub-region is within the same preset brightness value interval, and N is a positive integer;

Adjust the refresh frequency of the first brightness sub-region to the first sub-target refresh frequency, the first brightness sub-region is any brightness sub-region in the N brightness sub-regions, and the first sub-target refresh frequency is one of the N sub-target refresh frequencies The sub-target refresh rate corresponding to the first brightness sub-region.
