step S100: and when a screen refresh rate adjusting instruction is received, calculating the interface refresh rate of the current application of the terminal.
In this step, the screen refresh rate adjustment instruction is triggered according to a set time interval mode or an event trigger mode, where the trigger mode is specifically described as follows:
the method comprises the steps that firstly, triggering is carried out according to an event triggering mode, for example, when the current application of the terminal is started or awakened, a screen refresh rate adjusting instruction is automatically sent out; or when the current application of the terminal is switched, namely the current application is switched to the next application, automatically sending a screen refresh rate adjusting instruction.
Triggering according to a set time interval mode, automatically sending a screen refresh rate adjusting instruction after the set time interval of the previous sampling is finished, recalculating the interface refresh rate of the current application of the terminal in the next preset sampling time, and calculating the interface refresh rate of the current application of the terminal in real time so as to dynamically adjust the screen refresh rate of the terminal in real time; the time interval is set according to actual requirements, for example, the time interval is set to be 30ms, so that the adjustment times of the screen refresh rate in unit time can be reduced, the working efficiency of the terminal screen is improved, and the power consumption of the terminal is reduced.
In the step, when a screen refresh rate adjustment instruction is received, firstly, counting the number of image frames for interface refresh in the current application of the terminal within a preset sampling time; and then, calculating the interface refresh rate currently applied by the terminal according to the image frame number and the sampling time. The specific implementation mode is as follows:

In this step, the interface refresh rate currently applied by the terminal may also be calculated in other manners, and the embodiment of calculating the interface refresh rate currently applied by the terminal is not particularly limited herein.
Step S101: and adjusting the screen refresh rate of the terminal according to the interface refresh rate of the current application.
In this step, the initial screen refresh rate is a default value set by the system, and the specific implementation manner of adjusting the screen refresh rate of the terminal according to the currently applied interface refresh rate is as follows:
firstly, setting an interface refresh rate threshold according to an actual interface refresh rate range, namely: a first interface refresh rate threshold, which is generally a preset first interface refresh rate threshold with a value range of 5-20 frames/second, divides the interface refresh rate into two segments, and sets two scene modes corresponding to the two segments; namely: the method comprises the steps that in order to take visual effect and compatibility of screen parameters of most terminals into consideration, a first screen refresh rate is set corresponding to a first mode, and a second screen refresh rate is set corresponding to a second mode; wherein the first screen refresh rate is lower than the second screen refresh rate.
Specifically, if the interface refresh rate of the current application is less than or equal to the first interface refresh rate threshold, the corresponding scene mode is the first mode, and at this time, the screen refresh rate of the terminal is adjusted to be the first screen refresh rate, that is: reading a first screen refresh rate and a current screen refresh rate according to an interface provided by a screen driver, judging whether the first screen refresh rate is the same as the current screen refresh rate, and if not, updating the current screen change rate to be the first screen refresh rate; if the currently applied interface refresh rate is greater than the first interface refresh rate threshold, the corresponding scene mode is the second mode, and at this time, the screen refresh rate of the terminal is adjusted to be the second screen refresh rate, so that the screen refresh rate of the terminal can be dynamically adjusted, and the purpose of saving the electric quantity of the terminal is achieved.
Preferably, two appropriate interface refresh rate thresholds may also be set according to the actual interface refresh rate range, namely: the method comprises the steps that a first interface refresh rate threshold value and a second interface refresh rate threshold value are generally set, the value range of a preset second interface refresh rate threshold value is 5-10 frames/second, the value range of a preset third interface refresh rate threshold value is 10-20 frames/second, the interface refresh rate is divided into three sections, and three scene modes are set corresponding to the three sections; namely: in order to take visual effect and the compatibility of most of terminal screen parameters into consideration, a first mode, a second mode and a third mode are used, wherein a first screen refresh rate is set corresponding to the first mode, a second screen refresh rate is set corresponding to the second mode, and a third screen refresh rate is set corresponding to the third mode; the first interface refresh rate threshold is smaller than a second interface refresh rate threshold, the first screen refresh rate is the lowest, and the third screen refresh rate is the highest; and judging which scene corresponds to according to the currently applied interface refresh rate, the first interface refresh rate threshold value and the second interface refresh rate threshold value, and adjusting the screen refresh rate according to different scenes.
Specifically, if the interface refresh rate of the current application is less than or equal to the first interface refresh rate threshold, the corresponding scene mode is the first mode, and at this time, the screen refresh rate of the terminal is adjusted to be the first screen refresh rate; if the currently applied interface refresh rate is greater than the first interface refresh rate threshold and less than or equal to the second interface refresh rate threshold, the corresponding scene mode is a second mode, and at the moment, the screen refresh rate of the terminal is adjusted to be a second screen refresh rate; and if the currently applied interface refresh rate is greater than the second interface refresh rate threshold, the corresponding scene mode is a third mode, and at the moment, the screen refresh rate of the terminal is adjusted to be the third screen refresh rate.
In the embodiment of the invention, a plurality of interface refresh rate thresholds can be set according to actual requirements, the interface refresh rate is divided into a plurality of segments, a plurality of self-defined scene modes are set corresponding to the segments, different screen refresh rates are set corresponding to each self-defined scene mode, and the screen refresh rate of the terminal is adjusted according to the currently applied interface refresh rate, so that the screen refresh rate of the terminal can be flexibly and dynamically adjusted to achieve the purpose of saving the electric quantity of the terminal.
Further, after the screen refresh rate of the terminal is adjusted according to the currently applied interface refresh rate, the currently applied interface refresh rate of the terminal can be recalculated according to a set time interval mode or an event trigger mode; and then, adjusting the screen refresh rate of the terminal according to the recalculated interface refresh rate of the current application, and dynamically adjusting the screen refresh rate of the terminal in real time.
Further, after the screen refresh rate of the terminal is adjusted, an image is displayed according to the adjusted screen refresh rate.
In the embodiment of the invention, when a screen refresh rate adjusting instruction is received, the interface refresh rate of the current application of the terminal is calculated; and adjusting the screen refresh rate of the terminal according to the currently applied interface refresh rate. Therefore, the screen refresh rate of the terminal is dynamically adjusted according to the interface refresh rate of the current application, so that the power consumption of the terminal can be reduced, and the standby time of the terminal is prolonged.
In order to more clearly illustrate the embodiment of the present invention, the following describes in detail the flow of adjusting the screen refresh rate in the embodiment of the present invention, taking the first embodiment as an example:
in the first embodiment, two appropriate interface refresh rate thresholds are set according to the actual interface refresh rate range, that is: the first interface refresh rate threshold value is 5 frames/second and the second interface refresh rate threshold value is 20 frames/second, the interface refresh rate is divided into three segments, and three self-defined scene modes are set corresponding to the three segments, namely: a reading mode, a normal mode and an extreme speed mode;
when the interface refresh rate of the current application is less than or equal to the first interface refresh rate threshold value by 5 frames/second, the current scene mode of the terminal is considered as a reading mode; when the interface refresh rate of the current application is greater than a first interface refresh rate threshold value by 5 frames/second and less than a second interface refresh rate threshold value by 20 frames/second, the current scene mode of the terminal is considered to be a common mode; and when the currently applied interface refresh rate is greater than the second interface refresh rate threshold value by 20 frames/second, the current scene mode of the terminal is considered to be the top speed mode.
In the first embodiment, in order to consider both the visual effect, the compatibility of the screen parameters of most terminals, and the power consumption, in the reading mode, the screen refresh rate is set to 30 frames/second; in the normal mode, setting the screen refresh rate to be 45 frames/second; in the top speed mode, setting the screen refresh rate to be 60 frames/second; the mapping relationship corresponding to the interface refresh rate, the scene mode and the screen refresh rate is shown in table 1.
