Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The refresh rate refers to the number of times that the electron beam repeatedly scans an image on the screen, and the higher the refresh rate is, the better the stability of the displayed image is, and for the currently popular liquid crystal display or LED display, the refresh rate can be understood as the number of times that the screen is refreshed per second, and the refresh rate can be generally divided into a vertical refresh rate and a horizontal refresh rate, and the currently common refresh rate generally refers to the vertical refresh rate. The vertical refresh rate identifies the number of redraws of an image of a screen per second, i.e., the number of screen refreshes per second, in Hz. The higher the refresh rate, the better, the more stable the image, the more natural and clear the image display, the less impact on the eyes, but the higher the power consumption. The lower the refresh rate, the more flickering and jittering the image, the faster the eye is tired, but the less power is consumed.

With the increasing requirements of people on mobile terminals, the mobile terminals are required to have better audio-visual experience. Therefore, most of the existing mobile terminals have a screen that can support a high refresh rate, where the high refresh rate refers to any one of 90Hz, 120Hz, or 144 Hz. However, there are applications whose frame rates do not match these high refresh rates, which can result in wasted power consumption by the mobile terminal if the high refresh rate is still used while the mobile terminal is running the applications.

In the related art, the application programs with the frame rates which cannot be matched with the high refresh rate are placed in the blacklist, when the system runs the application programs in the blacklist, the power consumption of the mobile terminal is saved by reducing the screen refresh rate, and when the system does not run the application programs in the blacklist, the visual experience of a user is improved by adopting the high refresh rate. However, if the frame rate of the application program in the blacklist can already match the high refresh rate, if the blacklist is not updated timely, the application program that can already match the high refresh rate can continue to be operated at the low refresh rate, which is obviously not favorable for the visual experience of the user. Therefore, the adjustment of the screen refresh rate by using the blacklist is obviously not flexible enough, and the maintenance cost of the blacklist is high.

Therefore, what way to better consider the power consumption and the visual experience of the mobile terminal becomes a technical problem which needs to be solved urgently.

The embodiment of the disclosure aims to provide a new mode, which can better give consideration to the power consumption and the visual experience of the mobile terminal.

Fig. 1 is a flowchart illustrating a screen refresh rate adjustment method according to an exemplary embodiment, where the method is applied to a mobile terminal, as shown in fig. 1, and the method includes the following steps:

step 11: determining the operating parameters of a foreground application program;

step 12: determining whether the foreground application program is in an abnormal refreshing state or not according to the running parameters of the foreground application program and the current screen refreshing rate;

step 13: if the foreground application program is in a refresh abnormal state, determining a target screen refresh rate;

step 13: and adjusting the refresh rate of the screen to the target screen refresh rate.

Here, the mobile terminal may be a mobile phone, a tablet computer, a notebook computer, or a wearable device; wherein, wearable equipment can be intelligent wrist-watch or intelligent bracelet etc.. It is understood that the mobile terminal may include all mobile terminals having a display function.

Here, a foreground application is understood to be an application that is running in the foreground. The operation parameters of the foreground application include, but are not limited to, application process parameters and/or system process parameters that can be read by the foreground application in the operation process. The application process parameters include, but are not limited to: the application process identifier may be used to characterize the corresponding application process, for example, an identifier of an image rendering process in the application program is different from an identifier of a start process of the application program. System process parameters including, but not limited to: the identifier of the system process, the running time length of the system process, or the running times of the system process, and the like, where the identifier of the system process may be used to characterize the corresponding system process, for example, the identifier of the system process is displayed to be different from the identifier of the operating system process.

Here, the target screen refresh rate may be understood as a refresh rate matching the frame rate of the foreground application.

Here, the frame rate refers to the frequency rate at which pictures appear on the screen, and the higher the frame rate is, the more pictures are captured by human eyes, and the pictures look smoother. For example, if the frame rate of the application program running in the foreground is 60 frames per second, the corresponding target screen refresh rate is 60Hz; if the frame rate of the application program running in the foreground is 90 frames per second, the corresponding target screen refresh rate is 90Hz. It can be understood that if the frame rate of the application program running on the foreground is matched with the screen refresh rate, the foreground application program is not in a refresh abnormal state; and when the frame rate of the application program operated in the foreground is not matched with the screen refresh rate, the foreground application program is considered to be in an abnormal refresh state. That is, under the condition that the application program operated by the current station is displayed at the target refresh rate, the problem of overhigh power consumption caused by the fact that the screen refresh rate is higher than the frame rate can be solved, and the problem of poor visual experience caused by the fact that the screen refresh rate is lower than the frame rate can also be solved.

It should be noted that, for some game applications, some game applications do not have a high frame rate due to considerations such as development cost of the game applications, and therefore do not support a high screen refresh rate, and if these application programs are run on a mobile terminal set to the high refresh rate, power consumption of the mobile terminal is inevitably wasted. However, if the refresh rate of the screen of the mobile terminal is set to a low refresh rate in order to reduce power consumption, for applications with a high frame rate that can support a high screen refresh rate, the visual experience of the user is not good if the applications are run on the mobile terminal set to a low refresh rate.

Based on this, firstly, compared with the related art in which the screen refresh rate is adjusted by means of blacklist recording, in the embodiment of the present disclosure, since the operating parameter of the foreground application is determined, and whether the foreground application program is in the refresh abnormal state is determined according to the operating parameter of the foreground application, the adjustment is more flexible, and the phenomenon of misadjustment caused by untimely updating of the blacklist is reduced. Secondly, the embodiment of the disclosure can obtain the judgment result of whether the foreground application program is in abnormal refresh in real time based on the operation parameters of the foreground; then based on the judgment result, when the foreground application program is in the abnormal refreshing state, the refreshing rate of the screen is adjusted to the target screen refreshing rate, so that the current screen refreshing rate of the mobile terminal cannot be higher than the target screen refreshing rate corresponding to the foreground running application program, the power consumption of the mobile terminal is wasted, the visual experience of a user on the mobile terminal is not influenced due to the lower target screen refreshing rate corresponding to the foreground running application program, and the consideration of the power consumption and the visual experience is realized. The performance of the mobile terminal is improved.

In summary, compared with the related art, the embodiment of the disclosure has higher adjustment flexibility and less mis-adjustment phenomenon, and can better realize the consideration of power consumption and visual experience of the mobile terminal, thereby further improving the performance of the mobile terminal.

It should be added that, for some applications, the same application is given different frame rates in different use states or different display pages, and therefore, the application has different target screen refresh rates in different use states or different display pages. Based on this, in some embodiments, the determining the operation parameter of the foreground application may include:

and when the application program is operated, determining the operation parameters of the foreground application program according to a preset period.

Thus, the present embodiment can timely update the determination result of whether the foreground application is in the refresh abnormal state according to the predetermined period. Based on the judgment result, the refresh rate of the screen is adjusted in time, and the timeliness of adjustment is improved.

In other embodiments, the determining the operating parameter of the foreground application may include:

and determining the running parameters of the foreground application program in response to the page change of the foreground application program.

Therefore, the method and the device for judging whether the foreground application program is in the abnormal refreshing state can be updated in time when the page of the foreground application program changes. And based on the judgment result, the refresh rate of the screen is adjusted in time, so that the adjustment timeliness is improved.

In the above embodiment, the refresh rate of the screen can be adjusted in time for the foreground application under different use states or different display pages, so that the refresh rate of the screen can be adapted to the current display state of the foreground application in time, the timeliness of screen adjustment is further improved, the power consumption and the visual experience of the mobile terminal are further considered, and the performance of the mobile terminal is improved.

It should be noted that, referring to fig. 2, fig. 2 is a scene diagram illustrating a method for adjusting a screen refresh rate according to an exemplary embodiment, as shown in fig. 2, a source data end of an application program will put a generated image data frame into a queue buffer, and a display system in system service of a mobile terminal will request to display the image data frame from the queue buffer and perform display processing on the image data frame. The image data frame is subjected to display processing, which includes but is not limited to: the image data frame is subjected to image synthesis processing. The display system in the android system is SurfaceFlinger. The role of the surfaceflag here is to receive graphical display data from multiple sources, synthesize it, and then send it to a display device.

The queue buffer here may be: the image rendering process of the application is used to store a temporary buffer of frames of image data.

It can be understood that the source data side of the application performs the generation of the image data frames according to the current frame rate of the application. Taking the current frame rate of the application program as 90 frames/second as an example, the source data end of the application program stores data to the queue buffer at the speed of 90 frames per second, and the display system requests an image data frame from the queue buffer according to the current refresh rate of the mobile terminal, for example, the current refresh rate of the mobile terminal is 60Hz, and the image data frame obtained from the queue buffer per second is 60 frames; as another example, if the current refresh rate of the mobile terminal is 120Hz, the frames of image data obtained from the queue buffer per second would be 120 frames. Obviously, if the rate of the image data frames generated by the source data side of the application program is not consistent with the rate of the image data frames acquired by the display system, the above phenomenon that the power consumption of the mobile terminal is wasted or the display effect is poor will occur.

In some exemplary embodiments, the operating parameters of the foreground application include, but are not limited to: waiting time for queue calling in an image rendering process in a first unit time length; referring to fig. 3, fig. 3 is another flowchart illustrating a method for adjusting a screen refresh rate according to an exemplary embodiment, as shown in fig. 3, in step 11, the determining an operation parameter of a foreground application may include:

step 111: monitoring an image rendering process of the foreground application program, and determining the waiting time of queue calling in the image rendering process within a first unit time;

in step 12, the determining whether the foreground application is in an abnormal refresh state according to the operating parameters of the foreground application and the current screen refresh rate may include:

step 121: and if the waiting time is greater than the time threshold, determining that the foreground application program is in an abnormal refreshing state, wherein the time threshold is determined according to the current screen refreshing rate.

Here, the image rendering process is configured to receive image data of an application program and render and display a corresponding image based on the image data. That is, the image rendering process is a process of displaying image data of an application on a screen in the form of an image. Here, the image rendering process stores frames of image data in a queue. The image rendering process renders the display image by calling the frame of image data in the queue.

Here, the first unit time length may be a default unit time length, for example, a unit time length in seconds.

It is added that, under the condition that the frame rate of the foreground application program is consistent with the current screen refresh rate, the queue call in the image rendering process of the foreground application program hardly needs to wait. That is, the application program generates a frame of image data, and the image rendering process calls the frame of image data. If the frame rate of the foreground application is not consistent with the current screen refresh rate, for example, the frame rate of the current application is higher than the current screen refresh rate, the application generates a frame of image data, and the image rendering process may not have time to call away the frame of image data.

For example, referring to fig. 4, as shown in fig. 4, when the frame rate of the current application program is consistent with the current screen refresh rate, only one frame of image data is to be called, and at this time, the set duration threshold may be set according to the current screen refresh rate, for example, the set duration threshold is the duration for calling one frame of image data. For example, the duration threshold may be set to 153us, which is the duration for calling one frame of image data.

For example, referring to fig. 5, as shown in fig. 5, when the frame rate of the foreground application is not consistent with the current screen refresh rate, there are a plurality of frame image data waiting to be called, and the waiting time at this time is greater than the time threshold. Illustratively, when the waiting duration is 5.978ms, the waiting duration is greater than the duration threshold 153us, so in the scenario shown in fig. 5, it may be determined that the frame rate of the foreground application is inconsistent with the current screen refresh rate, that is, the foreground application is in a refresh abnormal state.

For example, if the waiting duration is greater than the duration threshold, it indicates that the frame rate of the application is faster than the current screen refresh rate, that is, the current screen refresh rate cannot keep up with the frame rate of the application, which affects the visual experience of the user, and then the screen refresh rate needs to be increased.

In the embodiment of the disclosure, the waiting time for queue calling in the image rendering process in the first unit time length is determined by monitoring the image rendering process of the foreground application, and then if the waiting time is judged to be greater than the time length threshold, the foreground application is determined to be in the refresh abnormal state, so that whether the foreground application is in the refresh abnormal state can be conveniently and quickly judged, and the adjustment efficiency is improved.

It should be added that the waiting time of the image data frame in the queue of the image rendering process not only depends on the current screen refresh rate, but also needs to take into account the system operating conditions of the mobile terminal and other factors.

In some embodiments, the method further comprises:

and determining the time length threshold according to the current screen refresh rate and the system operation condition.

The system operation conditions include: at least one of the memory remaining status of the system, the CPU performance status or the network signal status. It can be understood that the less the system memory remains, the longer the duration threshold can be set; the longer the CPU performance condition is, the longer the time length threshold value can be set; the duration threshold may also be set longer the worse the network signal condition.

For example, referring to fig. 4 again, if 153us in fig. 4 only considers the time length required for calling one frame under the current screen refresh rate, when the call time length of the system is increased due to the phenomenon of memory retention, the system may mistakenly determine that the foreground application is in a refresh abnormal state, thereby causing a false adjustment phenomenon.

In the embodiment of the disclosure, the duration threshold is determined according to the current screen refresh rate and the system operation condition, so that the phenomenon that the duration threshold set only by considering the current screen refresh rate and neglecting the system operation condition is taken as a judgment factor, the obtained judgment result is inaccurate, and the phenomenon of misadjustment is reduced.

In other embodiments, the determining the target screen refresh rate may include:

Here, the waiting time period may be obtained by calling a corresponding timer through the read queue. Illustratively, the waiting duration is determined by reading the end time and the start time of the corresponding buffer of the queue call. Here, the buffer corresponding to the queue call is the queue buffer described in the above embodiment.

In some embodiments, taking the first unit duration as 1000ms, that is, 1 second as an example, the determining the target screen refresh rate according to the current screen refresh rate and the waiting duration may be performed according to the following calculation formula (1).

(1000-wait duration)/current screen refresh rate (1)

Illustratively, if the current screen refresh rate is 60Hz, the first unit time length is 1s, and the waiting time length is 333ms, that is, within the time length of subtracting 333ms from 1000ms, that is, within the time length of 667ms, 60 frames are called, 90 frames are calculated per second, and thus, the target screen refresh rate is then determined by the calculated frame rate of the application. Here, if the calculated frame rate of the application is 90 frames/sec, the corresponding target screen refresh rate is 90Hz.

For example, in the case that the current screen refresh rate is 60Hz, if the frame rate of the application program is 90 frames and seconds, the waiting time length is 333ms; if the frame rate of the application is 120 frames/second, the waiting time is 500ms.

Illustratively, in the case where the current screen refresh rate is 90Hz, if the frame rate of the application is 120 frames/second, the waiting time period corresponds to 253ms.

Therefore, the target screen refresh rate can be accurately obtained through calculation, and the refresh rate of the screen is adjusted based on the target screen refresh rate.

In other embodiments, the determining the target screen refresh rate according to the current screen refresh rate and the wait duration may further include:

and determining the target screen refresh rate corresponding to the waiting time length and the current screen refresh rate according to the corresponding relation among the current screen refresh rate, the waiting time length and the target screen refresh rate.

Therefore, according to the embodiment of the disclosure, the corresponding relation between the waiting duration, the current screen refresh rate and the target screen refresh rate is stored in the local or cloud server in advance, so that the system can directly obtain the target screen refresh rate corresponding to the waiting duration, the system does not need to calculate, the calculation resources are reduced, and the processing efficiency is improved.

The cloud server obtains the target screen refresh rate, the storage resources in the mobile terminal do not need to be wasted, and the performance of the mobile terminal can be further improved.

In some embodiments, referring to fig. 6, fig. 6 is a flowchart illustrating a method for adjusting a screen refresh rate according to an exemplary embodiment, where, as shown in fig. 6, the determining the operating parameter of the foreground application in step 11 may include:

step 112: monitoring a display system process, and determining the synthesis times of the image data frames in the display system process in a second unit time length;

in step 12, the determining whether the foreground application is in an abnormal refresh state according to the operating parameters of the foreground application and the current screen refresh rate includes:

step 122: and if the synthesis times are less than a time threshold value, determining that the foreground application program is in a refresh abnormal state, wherein the time threshold value is determined according to the current screen refresh rate.

Referring to fig. 2, as mentioned above, if the rate of the image data frame generated by the source data end of the application is not consistent with the rate of the image data frame acquired by the display system, the above-mentioned phenomenon of wasting the power consumption of the mobile terminal or having poor display effect may occur.

The display system process here is a process generated by the display system executing the service.

The second time unit length may be different from or the same as the first time unit length. For example, the first unit time length may be 1 second, the second unit time length may be 2 seconds, and the like, and the second unit time length is not limited in any way.

The number threshold may be the number of requests for the image data frame by the display system, or the number of image combinations based on the image data frame by the display system. In general, the threshold number of times corresponds to the current screen refresh rate. It is understood that, taking the second unit duration as 1 second as an example, if the current screen refresh rate is 60Hz, the corresponding number threshold may be 60 times. Of course, the unit duration here can also be set to 2s, and if the current screen refresh rate is 60Hz, the corresponding threshold of times can be 120 times, and so on.

For example, if the number of composition times is less than the number threshold, it indicates that the frame rate of the application is slower than the current screen refresh rate, that is, the current screen refresh rate is too fast, which may cause power consumption loss, and then the refresh rate of the screen needs to be increased.

Therefore, in the embodiment of the present disclosure, the synthesis frequency for the image data frame in the display system process in the second unit duration is determined by monitoring the display system process, and then if it is determined that the synthesis frequency is smaller than the frequency threshold, it is determined that the foreground application is in the refresh abnormal state, so that it can be conveniently and quickly determined whether the frame rate of the application is matched with the current screen refresh rate, and the adjustment efficiency is improved.

Therefore, the frame rate of the foreground application program can be accurately obtained by calculating the synthesis times, so that the target screen refresh rate can be calculated, and the screen refresh rate can be adjusted to the target screen refresh rate. The calculation mode is simple and quick.

In other embodiments, the method further comprises:

Therefore, the current screen refresh rate is intelligently maintained by judging that the foreground application program is not in the refresh abnormal state, and the power consumption and the visual experience of the mobile terminal can be further ensured.

In other embodiments, the method further comprises:

Here, the preset refresh rate may be used for a preset screen refresh rate, and may be a fixed refresh rate.

In other embodiments, the preset refresh rate may also be a refresh rate corresponding to a frame rate of an application program commonly used by a user. For example, the application program commonly used by the user is a chat-type application program, and the application program can support a high refresh rate, and the preset refresh rate is 90Hz or one of 120Hz and 144 Hz. Of course, the preset refresh rate can be changed according to the change of the application program commonly used by the user.

In some embodiments, the preset refresh rate is set to the maximum refresh rate of the mobile terminal in order to preferentially satisfy the visual experience of the mobile terminal. Illustratively, the refresh rate of the screen is adjusted to a maximum refresh rate when the foreground application exits.

In the embodiment of the disclosure, when the foreground application exits, the refresh rate of the screen is restored to the preset refresh rate, so that when the user starts another application program again, the user can better match the other application program started next time, the frequent adjustment phenomenon of the screen refresh rate is reduced, and the performance of the mobile terminal is improved.

Further, the present disclosure provides a specific embodiment to further understand the method for adjusting the screen refresh rate provided by the embodiment of the present disclosure.

Referring to fig. 7, fig. 7 is a flowchart illustrating a method for adjusting a screen refresh rate according to an embodiment, where as shown in fig. 7, the method includes:

step 71: starting an application;

here, the newly launched application may be considered a foreground application. The application here can be understood as a foreground application described in the above embodiments.

Step 72: application operation;

here, the application runtime may generate some operation parameters, i.e. the determination of the operation parameters at which the application starts to be executed. This step may be understood as "determining the operating parameters of the foreground application" in the above embodiments. Illustratively, the step may further include: an image rendering process of the application is monitored, and/or a display system process is monitored.

Step 73: the waiting time called by the queue in the image rendering process exceeds a time threshold;

in this step 73, it may be understood that "determining whether the foreground application is in the refresh abnormal state according to the operating parameter of the foreground application and the current screen refresh rate" in the above embodiment, "and determining that the foreground application is in the refresh abnormal state if the waiting duration is greater than the duration threshold.

Step 74: and increasing the screen refresh rate to operate at the maximum refresh rate of the screen.

Here, if the waiting duration exceeds the duration threshold, it indicates that the frame rate of the application is slower than the current screen refresh rate, and therefore, the application can be operated by adjusting the screen refresh rate to the maximum refresh rate, so that the adjusted screen refresh rate can quickly match the frame rate of the application.

Step 75: the times of synthesis for the image data frames in the process of the display system are smaller than a time threshold value;

this step 74 may be understood as "determining whether the foreground application is in the abnormal refresh state according to the operating parameters of the foreground application" and "determining that the foreground application is in the abnormal refresh state if the synthesis frequency is less than the frequency threshold" in the foregoing embodiment.

Step 76: reducing the screen refresh rate;

here, if the number of times of composition is less than the number threshold, it indicates that the frame rate of the application is faster than the current screen refresh rate, and therefore, the screen refresh rate may be decreased so that the adjusted screen refresh rate can match the frame rate of the application.

In some embodiments, the reducing the screen refresh rate may include:

the screen refresh rate is reduced at predetermined reduction levels, for example, at 30Hz per level.

Step 77: the application exits;

this step 77 corresponds to "foreground application exit" as described in the above embodiment.

Step 78: the screen refresh rate is restored to the maximum refresh rate.

This step 78 is equivalent to "adjust the refresh rate of the screen to the preset refresh rate when the foreground application exits" in the above embodiment.

The method and the device for improving the screen refresh rate improve the screen refresh rate by detecting that the waiting time for queue calling in the image rendering process exceeds a time threshold, or reduce the screen refresh rate by detecting that the synthesis times for the image data frames in the display system process is less than a time threshold. Therefore, the refresh rate of the screen can be adjusted more flexibly, so that the power consumption and the visual experience of the mobile terminal are better considered, and the performance of the mobile terminal is improved.
