The method for adjusting the screen refresh rate according to the exemplary embodiment of the present disclosure is specifically described below with reference to fig. 3. As shown in fig. 3, the screen refresh rate adjustment method may include the following steps S310 to S330:

in step S310, a preset input event is received.

The preset input event refers to an operation of a user inputting a preset type, and is generally an input event interacting with a graphical user interface displayed on a screen, for example, a user selects content, inputs content, moves a page, jumps to other pages, and the like in the graphical user interface through input devices such as a mouse, a keyboard, keys, and the like. If the electronic device is a touch terminal, the preset input event may include a touch event, for example, when a user clicks a touch screen or performs a touch operation such as sliding or pressing on the touch screen, it may be determined that the preset input event is received.

In an alternative embodiment, the screen refresh rate may be set to a first preset value when a preset input event is received. The receiving of the preset input event indicates that the device is currently in an interactive state, and a higher screen refresh rate is required, so the first preset value may be a higher value, for example, the highest refresh rate supported by the device screen (e.g., 90fps and 120fps), or the highest refresh rate required by the currently running App, or other empirical values, which is not specifically limited by the present disclosure.

In step S320, timing is started from the end of the preset input event to record the interval time to the next preset input event.

In the exemplary embodiment, the system may maintain a timer that starts from 0 when a preset input event ends until the next preset input event occurs. The timer records the time interval from the preset input event which is currently ended to the next preset event. Generally, in the timing process, whether the next preset input event occurs needs to be monitored in real time, and the system can perform monitoring through a specific process. For example, in an Android system, input events received by a driver layer all enter a dev/input directory and scan information in dev/input through an input reader process, so that all input events at each moment can be monitored, and whether preset input events exist is detected.

And step S330, adjusting the screen refresh rate according to the timed duration.

The timed duration indicates how long the current system has not received any preset input event, meaning how long the user has not actively initiated the interaction, and therefore the screen refresh rate can be adjusted. The screen refresh rate can be reduced as often as appropriate.

In an alternative embodiment, in the process of timing accumulation, the screen refresh rate may be adjusted downward in a step manner according to a predetermined correspondence relationship between the time length and the screen refresh rate, for example, when the time length of timing reaches 50ms, the screen refresh rate is adjusted downward from 120fps to 90fps, when the time length reaches 100ms, the screen refresh rate is adjusted downward to 60fps, when the time length reaches 300ms, the screen refresh rate is adjusted downward to 30fps, and so on. Therefore, the down-regulation process of the screen refresh rate is smooth, and a user does not feel the down-regulation process.

In an alternative embodiment, when the timed duration reaches the first threshold, the screen refresh rate may be adjusted to a second preset value. The first threshold is a time threshold for judging whether the duration of the next preset input event which is not input by the user is too long, and can be set according to experience or actual requirements. For example, the first threshold may be determined according to the response time of the currently running App, and if the page refresh response time of App xyz is 50ms, the first threshold is set to 50 ms; or according to historical operation data of a user in the App, counting the interval time of two continuous preset input events (if conditions can be set, the two continuous preset input events within 5s are regarded as continuous, otherwise, the two continuous preset input events are regarded as discontinuous), and taking the maximum value or the average value plus four times of standard deviation as the first threshold. The second preset value is smaller than the first preset value, which indicates a screen refresh rate required by the App when user interaction is inactive, and may be set according to experience and actual requirements in combination with hardware parameters of the screen, for example, for a screen that supports a refresh rate of 120fps at maximum, the second preset value may be set to 60fps, or in some App scenes with a low page refresh requirement, such as an App with text content as a main, e.g., an electronic book, news, etc., a lower second preset value may be set.

From the above, in the process of timing, once the set condition is reached, such as the time length reaches the first threshold value, the adjustment of the screen refresh rate can be implemented, and the adjustment does not need to be performed after the timing is finished.

In an alternative embodiment, referring to fig. 4, the first threshold may be determined by the following steps S410 and S420:

in step S410, when the application program starts to run, a first threshold is set according to the response time of the application program.

In step S420, during the running of the application program, when a preset input event is received, the first threshold is adjusted according to the last preset input interval time.

When the application program starts to run, the first threshold value may be set as the response time of the application program as the initial value of the first threshold value.

The previous preset input interval time is an interval time from the end of the previous preset input event to the start of the current preset input event, and is also a time length counted by a timer after the end of the previous preset input event. That is, during the running of the application program, each time a new preset input event is received, a last preset input interval time may be determined, where the last preset input interval time represents a current operation frequency of the user, and the first threshold may be adaptively adjusted according to the last preset input interval time.

Generally, the first threshold may be appropriately increased when the last preset input interval is longer, and the first threshold may be appropriately decreased when the last preset input interval is shorter, but the disclosure is not limited thereto. Several embodiments are further provided below:

referring to fig. 5, step S420 may specifically include the following steps S510 to S530:

in step S510, during the running of the application program, when a preset input event is received, a last preset input interval time is obtained.

In step S520, if the previous preset input interval is greater than the second threshold, the first threshold is updated by the sum of the previous preset input interval and the preset step size.

Step S530, if the last preset input interval time is less than the second threshold, the first threshold is updated by subtracting the preset step length from the first threshold;

the preset step size is a step value of time increase or decrease determined according to experience or actual demand, and a smaller value, such as 10ms, 20ms, etc., can be generally adopted. The second threshold is larger than the first threshold and is another empirical value or a calculated value for measuring time, for example, the second threshold may be the sum of the first threshold and a preset step length, and the second threshold is changed during the dynamic update of the first threshold.

The first threshold is denoted by T1, the second threshold is denoted by T2, s denotes a preset step size, and B denotes a last preset input interval time. The T1 update procedure is as follows:

if B > T2, then T1 ═ B + s;

if B < T2, T1 ═ T1-s.

In this way, the updating process of the first threshold is smoother, and can better adapt to the interaction state of the user.

The (second) T1 update procedure may also be as follows:

if B > T1+ s, then T1 ═ B + s;

if B is T1+ s, T1 is T1-s.

The (third) T1 update procedure may also be as follows:

if B > T1+ s, T1 ═ T1+ s;

if T1-s < B < T1+ s, then T1 remains unchanged.

If B < T1-s, then T1 ═ T1-s.

The (tetra) T1 update procedure may also be as follows:

if B > T1+ s, then T1 ═ B + s;

if T1-s < B < T1, then T1 ═ T1-s;

if B < T1-s, then T1 is T0 and T0 is the response time of the application.

In addition, in any of the above manners, when the first threshold is updated, the response time of the application program may be taken as the minimum value of the first threshold, for example, the response time is 50ms, and when the first threshold is reduced to 50ms, the reduction is not continued, so as to ensure that the first threshold is not lower than the response time, thereby maintaining the basic screen refresh requirement of the application program.

Based on the above, in the present exemplary embodiment, the time is counted from the end of the preset input event, and the screen refresh rate is adjusted according to the length of the time. On one hand, the timing duration represents how long the next preset event is not performed from the time when the user performs the preset input event, the current human-computer interaction state is reflected, the screen refresh rate is adjusted according to the timing duration, generally, the screen refresh rate is reduced, the current interaction requirement can be met, and meanwhile, unnecessary refreshing of the screen is reduced, so that the resource utilization efficiency is improved, and the problems of power consumption increase, serious heating and the like caused by high refresh rate are solved. On the other hand, no matter which App runs, the screen refresh rate can be dynamically adjusted according to the time length of the timing, and the screen refresh rate is prevented from being unchanged when the App runs, so that the scheme has higher flexibility compared with the related technology and has stronger universality for various different apps.

In an alternative embodiment, during the time counting process, as shown in fig. 6, the following steps S610 and S620 may also be performed:

in step S610, when the next preset input event is received, timing is stopped.

In step S620, the timing is restarted from the end of the next preset input event.

As can be seen from the steps in fig. 4, when each preset input event is ended, timing is started from 0, and when the timing reaches a set condition, the screen refresh rate is triggered and adjusted, and App continues to run; when the next preset input event is received, timing is stopped, timing can be cleared, and a higher screen refresh rate can be recovered; when the next preset input event ends, timing is restarted from 0 and the adjustment of the screen refresh rate is again triggered when the condition is reached. That is to say, in the App running period, the interval time of the user for presetting the input event can be recorded in real time in the whole course, and the screen refresh rate is continuously and dynamically adjusted according to the interval time, so that the robustness of the scheme is improved.

if the last preset input interval time is larger than the second threshold, updating the first threshold by the sum of the last preset input interval time and the preset step length;

if the last preset input interval time is smaller than a second threshold, subtracting a preset step length from the first threshold to update the first threshold;

wherein the second threshold is greater than the first threshold.

Claims

1. A method for adjusting a screen refresh rate, comprising:

receiving a preset input event;

starting timing from the end of the preset input event to record the interval time to the next preset input event;

and adjusting the screen refresh rate according to the timed duration.

2. The method of claim 1, wherein, in performing timing, the method further comprises:

stopping timing when the next preset input event is received;

and restarting timing from the end of the next preset input event.

3. The method of claim 1, further comprising:

and when a preset input event is received, setting the screen refresh rate to be a first preset numerical value.

4. The method of claim 3, wherein adjusting the screen refresh rate based on the timed length comprises:

when the timed duration reaches a first threshold value, adjusting the screen refresh rate to a second preset value; the second preset value is smaller than the first preset value.

5. The method of claim 4, wherein the first threshold is determined by:

when an application program starts to run, setting the first threshold according to the response time of the application program;

during the running of the application program, when a preset input event is received, adjusting the first threshold according to the last preset input interval time; the last preset input interval time is the interval time from the end of the last preset input event to the start of the current preset input event.

6. The method of claim 5, wherein adjusting the first threshold value according to a last preset input interval time when a preset input event is received during the running of the application program comprises:

during the running period of the application program, when a preset input event is received, acquiring the last preset input interval time;

if the last preset input interval time is larger than a second threshold, updating the first threshold by the sum of the last preset input interval time and a preset step length;

if the last preset input interval time is smaller than the second threshold, the first threshold is updated by subtracting the preset step length from the first threshold;

wherein the second threshold is greater than the first threshold.

7. The method of any one of claims 1 to 6, wherein the preset input event comprises a touch event.

8. A screen refresh rate adjustment apparatus, comprising:
