Description

Screen brightness adjusting method and device, storage medium and electronic equipment

Technical Field

The technical scheme of the disclosure relates to the technical field of thermal management, and in particular relates to a screen brightness adjusting method and device, a storage medium and an electronic device.

Background

Currently, most terminals, such as mobile phones, have a function of automatically adjusting the brightness value of the screen. The above functions of the terminal can provide a feasible method for the temperature control function of the terminal. Specifically, it is possible to suppress an increase in the temperature of the terminal by decreasing the luminance value of the screen when the temperature of the terminal reaches a certain value.

For example, the maximum brightness value of the screen may be limited to 1000 nits when the temperature of the terminal reaches 35 ℃, and 800 nits when the temperature of the terminal reaches 37 ℃. In the above method, when the temperature of the terminal was in the range of [35 ℃ C., 37 ℃ C.), the maximum luminance values of the terminal were all 1000 nits. That is, when the temperature of the terminal fluctuates within the above temperature range, the maximum brightness value of the screen is maintained, and only when the temperature of the terminal reaches 37 ℃, the maximum brightness value of the screen is changed from 1000 nit to 800 nit.

The screen brightness adjusting method according to the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

Fig. 1 is a flowchart illustrating a screen brightness adjustment method according to an exemplary embodiment of the present disclosure. As shown in fig. 1, the exemplary embodiment method may be applied to a terminal including, but not limited to, a mobile phone, a notebook computer, a desktop computer, an ipad, etc. Specifically, the method of this exemplary embodiment may be executed by an operating system of the terminal, where the operating system includes, but is not limited to, an android (android) system, an IOS system, and the like. As shown in FIG. 1, the exemplary embodiment method may include the steps of:

in step 100, a first temperature value of the terminal is determined in response to determining that the adjustment of the brightness value of the screen is triggered.

In an alternative example, the temperature value may be based on a measured temperature value of the terminal. A brightness value that triggers an adjustment screen is determined. Optionally, the terminal may trigger measurement of the temperature value of the terminal every first time interval. Wherein. The temperature value of the terminal refers to the shell temperature of the terminal. The terminal measures one temperature value at a time and determines the brightness value triggering the adjustment screen.

In one optional example, the first temperature value of the terminal may be determined based on a case temperature of the terminal. The shell temperature of the terminal can be obtained by an operating system of the terminal according to the temperature fitting of each device in the terminal.

Specifically, the operating system of the terminal may detect the temperature of each device inside the terminal in real time. For example, the temperature of devices such as a CPU (Central Processing Unit), a motherboard, and a battery inside the terminal can be detected in real time. And then, fitting according to a preset algorithm to obtain the shell temperature of the terminal.

Optionally, the first temperature value may be a current temperature value of the terminal shell temperature, or may be an average value of the shell temperature of the terminal within a preset time period.

In an alternative example, the terminal may also determine to trigger adjusting the brightness value of the screen based on other conditions, such as a received brightness bar adjustment instruction or a change in ambient lighting.

In an optional example, in case that it is determined to trigger adjustment of a brightness value of a screen based on a brightness bar adjustment instruction or a change in ambient illumination, the terminal may determine a temperature value of the terminal measured at the time of trigger adjustment of the brightness value of the screen as the first temperature value.

In step 102, a first temperature control brightness value corresponding to the first temperature value is determined according to a preset temperature control curve.

The temperature control curve is a curve of the maximum brightness value of the screen changing along with the terminal temperature.

In an optional example, the temperature control curve can be preset by related staff based on actual conditions and stored in the cloud. And when the terminal is started every time, the temperature control curve is automatically loaded from the cloud.

For example, the temperature control curve may be as shown in fig. 2. The data structure of the temperature control curve is a three-dimensional array: namely, the temperature control curve = { [ temperature value 1, luminance value 1, slope 1], [ temperature value 2, luminance value 2, slope 2], [ temperature value 3, luminance value 3, slope 3] … … }.

The slope is used to indicate the degree of bending of the temperature control curve. For example, "slope 1" in [ temperature value 1, luminance value 1, slope 1] described above is used to indicate that the slope of the curve at (temperature value 1, luminance value 1) is "slope 1".

After the operating system of the terminal determines the first temperature value of the terminal, a first temperature control brightness value corresponding to the first temperature value can be obtained according to the preset temperature control curve.

For example, the partial temperature control curve shown in fig. 2 can be expressed in the case of differentiation as in the case of fig. 3. In the figure, x2 (temperature value 2), y2 (brightness value 2), x3 (temperature value 3), and y3 (brightness value 3) are known values. When the operating system of the terminal detects a first temperature value of the current terminal, for example, x, a corresponding y value, that is, a first temperature control brightness value corresponding to the first temperature value, may be obtained according to two points (x 2, y 2) and (x 3, y 3) adjacent to the point.

Specifically, the above process may be represented as:

first temperature control brightness value

In step 104, the brightness value of the screen is adjusted based on at least the first temperature control brightness value.

In an alternative example, in case that it is determined to trigger the adjustment of the brightness value of the screen based on the measured temperature value of the terminal, the terminal may adjust the brightness value of the screen based on the first temperature-controlled brightness value and the current brightness value of the screen.

Wherein if the current brightness value of the screen is greater than the first temperature control brightness value, the brightness value of the screen may be reduced to the first temperature control brightness value.

In an alternative example, in the case that it is determined to trigger the adjustment of the brightness value of the screen based on the brightness bar adjustment instruction or the change of the ambient light, the terminal may adjust the brightness value of the screen based on a desired brightness value of the screen and the first temperature-controlled brightness value.

Wherein if the desired brightness value is greater than the first temperature control brightness value, the brightness value of the screen is adjusted to the first temperature control brightness value, and if the desired brightness value is less than or equal to the first temperature control brightness value, the brightness value of the screen is adjusted to the desired brightness value.

Compared with the situation that the maximum brightness value of the screen is kept unchanged when the temperature of the terminal changes within the same temperature range in the related art, each temperature value of the terminal disclosed by the embodiment of the disclosure has a temperature control brightness value corresponding to the temperature value, the brightness value of the current screen is adjusted based on the temperature control brightness value corresponding to any acquired temperature value, and the fluctuation of the brightness of the screen can be reduced.

Fig. 4 is a flowchart illustrating another screen brightness adjustment method according to an exemplary embodiment of the present disclosure. In the description of this embodiment, the same steps as those in any of the foregoing embodiments will be briefly described, and detailed descriptions thereof will be omitted, specifically referring to any of the foregoing embodiments. As shown in FIG. 4, the exemplary embodiment method may include the steps of:

in step 400, at intervals of a first duration, triggering measurement of a temperature value of the terminal.

In this example, the determination may trigger the adjustment of the brightness value of the screen every first time period, wherein the terminal may determine to trigger the adjustment of the brightness value of the screen based on the measured temperature value of the terminal. Specifically, the terminal may trigger to measure the temperature value of the terminal every time the first duration is set, so as to trigger to adjust the brightness value of the screen.

The first time period may be set by the relevant staff based on the actual situation.

In an alternative example, the first time period may be set to 10 seconds. Namely, every 10 seconds, the operating system of the terminal can be triggered to measure and acquire the temperature value of the terminal.

In another alternative example, the first time period may be set to 6 seconds. Namely, every 6 seconds, the operating system of the terminal can be triggered to measure and acquire the shell temperature of the terminal. Thereby increasing the frequency of adjusting the brightness value of the screen to a certain extent, so that the brightness fluctuation of the screen is smaller.

In step 402, it is determined whether the current temperature value of the terminal is greater than the previous temperature value.

From the foregoing, it can be obtained that the temperature value of the terminal is measured and obtained every time the operating system of the terminal is spaced for the first duration. In the description of the present example, the first time period is described as 10 seconds.

And when the temperature value of the terminal acquired by the operating system of the terminal is greater than the temperature value of the terminal acquired before 10 seconds, indicating that the terminal is in the temperature rise process. For example, the temperature value of the terminal obtained currently is 37 ℃, the temperature value of the terminal obtained 10 seconds ago is 36.8 ℃, and the temperature value of the terminal obtained 37 ℃ is greater than 36.8 ℃, which indicates that the terminal is in the temperature rise process. At this point, step 404a continues.

When the temperature value of the terminal acquired by the operating system of the terminal is less than or equal to the temperature value of the terminal acquired before 10 seconds, it is indicated that the terminal is in a cooling process or the temperature of the terminal is in a relatively stable stage. For example, the temperature value of the terminal obtained currently is 37 ℃, the temperature value of the terminal obtained 10 seconds ago is 37.2 ℃, and the temperature value of the terminal is less than 37.2 ℃ because the temperature of the terminal is less than 37.2 ℃, which indicates that the terminal is in the cooling process. At this point, step 404b continues.

In step 404a, the current temperature value is determined as the first temperature value.

In step 404b, an average temperature value of the terminal in a second time period is determined as the first temperature value.

In one optional example, the second duration may be greater than the first duration.

When the terminal calculates the average temperature value in the second time period, the average value of one or more temperature values measured in the second time period may be used as the average temperature value, and the average temperature value may be determined as the first temperature value.

For example, the first time period is 6 seconds, the second time period is 15 seconds, two temperature values are measured by the terminal in the second time period, and the terminal may use an average value of the two temperature values as an average temperature value of the terminal in the second time period, and then determine the average temperature value as the first temperature value.

In one optional example, the second duration may be greater than the first duration and a positive integer multiple of the first duration.

For example, when the first time period is the aforementioned 6 seconds, the second time period may be 12 seconds, 18 seconds, or the like. When the first time period is the aforementioned 10 seconds, the second time period may be 20 seconds, 30 seconds, or the like.

It should be noted that, in order to prevent the brightness fluctuation of the screen from being too large, the setting of the second time period described above is not necessarily too long. For example, it should be no greater than 30 seconds, etc.

In an optional example, when a difference between the historical temperature value and the average temperature value is greater than a preset difference, the average temperature value may be determined as the first temperature value.

And the historical temperature value is the temperature value of the terminal when the brightness value of the screen is triggered and adjusted last time. The preset difference may be, for example, 0.5 ℃,1 ℃, etc., which is not limited in the present disclosure.

For example, the historical temperature value may be 37 degrees celsius, and the preset difference may be 0.5 degrees celsius, for example. That is, when the average temperature value is less than 36.5 ℃, the average temperature value may be determined as the first temperature value.

The operation of this step will be described in detail by taking the following as an example:

if the historical temperature value is 37 ℃, the predetermined difference is 0.5 ℃. The first time period is 10 seconds, and the second time period is 30 seconds.

The temperature values of the terminal acquired by the terminal within 30 seconds may be, for example: the average temperature value within 30 seconds is 36.675 ℃ calculated at 37 ℃, 36.8 ℃, 36.5 ℃ and 36.4 ℃. Since the difference between 37 ℃ and 36.675 ℃ is 0.325 ℃ and less than the preset difference of 0.5 ℃, the step of determining the average temperature value as the first temperature value is not performed.

Correspondingly, the operating system of the terminal will continue to monitor the temperature of the terminal, and if the temperature of the terminal obtained after 10 seconds is 36 ℃. Then, the temperature value of the terminal acquired by the terminal within 30 seconds becomes: the average temperature value within 30 seconds is calculated to be 36.425 ℃ at 36.8 ℃, 36.5 ℃, 36.4 ℃ and 36 ℃. Since the difference between 37 ℃ and 36.425 ℃ is 0.575 ℃ and is greater than the preset difference by 0.5 ℃, at this time, the step of determining the average temperature value as the first temperature value is performed.

It should be noted that the above description of the data regarding the time length, the preset difference value, etc. is only illustrative, and is intended to enable those skilled in the art to better understand the technical solution of the present disclosure. In a specific implementation process, the above data may be set by a person skilled in the art based on practical situations, and the disclosure does not limit the present disclosure.

According to the screen brightness adjusting method, when the terminal is in a cooling process or the temperature of the terminal is in a relatively stable stage, and when the difference between the average temperature value of the terminal in a preset time period and the temperature value of the terminal in the previous trigger adjustment of the brightness value of the screen is greater than a preset difference value, the average temperature value is determined as the first temperature value, and a subsequent screen brightness adjusting process is performed according to the first temperature value. Therefore, on the premise of ensuring that the brightness fluctuation of the terminal screen is not large, the times of adjusting the screen brightness are further reduced.

In step 406, a first temperature control brightness value corresponding to the first temperature value is determined according to a preset temperature control curve.

In step 408, the brightness value of the screen is adjusted based on at least the first temperature control brightness value.

In an alternative example, a current brightness value of the screen may be obtained. And if the current brightness value of the screen is greater than the first temperature control brightness value, reducing the brightness value of the screen to the first temperature control brightness value.

And the current brightness value of the screen is used for representing the current brightness condition of the screen.

In an alternative example, the current brightness value of the screen may be obtained from a brightness bar of the terminal. Specifically, the current brightness bar state of the terminal may be automatically read by an operating system of the terminal, and the corresponding brightness value may be determined according to the read brightness bar state. The different brightness bar states correspond to different brightness values one to one, and the mapping relationship can be stored in an operating system of the terminal in advance. After the current brightness bar state is read, the corresponding brightness value can be determined according to the mapping relation.

In another alternative example, the operating system of the terminal may directly monitor the brightness value of the terminal screen in real time, which is not limited in this disclosure.

After the current brightness value of the terminal screen is obtained, the current brightness value may be compared with the first temperature control brightness value.

And when the current brightness value is larger than the first temperature control brightness value, reducing the brightness value of the screen from the current brightness value to the first temperature control brightness value, so that the power consumption is reduced, and the increase of the temperature is inhibited.

When the current brightness value is smaller than or equal to the first temperature control brightness value, the brightness value of the current terminal is within the current control range, and therefore the brightness value of the screen does not need to be adjusted.

In an alternative example, the first temperature control brightness value may be set to a maximum brightness value of the screen when the current brightness value is greater than the first temperature control brightness value. Therefore, the brightness value of the terminal screen cannot exceed the first temperature control brightness value in a subsequent period of time, and the temperature rise speed of the terminal is effectively inhibited. In this disclosure, once the terminal detects that the current brightness value of the screen is greater than the first temperature control brightness value, which indicates that the current brightness value of the screen does not meet the requirement of temperature control adjustment, the terminal may set the first temperature control brightness value as the maximum brightness value of the screen.

According to the screen brightness adjusting method provided by the embodiment of the disclosure, when the terminal is detected to be in a temperature rise process, when the temperature of the terminal rises, the current temperature value is determined as the first temperature value, and the brightness value of the terminal screen is adjusted based on the first temperature control brightness value corresponding to the first temperature value. Thereby better stabilizing the temperature rise rate. And when the terminal is detected to be in a cooling state or the temperature of the terminal is in a relatively stable stage, determining an average temperature value of the terminal in a preset time period as the first temperature value, and adjusting the brightness value of the terminal screen based on a first temperature control brightness value corresponding to the first temperature value. Therefore, on the premise of ensuring that the screen brightness fluctuation is not large, the times of adjusting the screen brightness are reduced.

Fig. 5 is a flowchart illustrating another screen brightness adjustment method according to an exemplary embodiment of the present disclosure. In the description of the present embodiment, the same steps as those in any of the foregoing embodiments will be briefly described, and detailed descriptions thereof will be omitted, so that reference may be made to any of the foregoing embodiments. As shown in FIG. 5, the exemplary embodiment method may include the steps of:

in step 500, if a brightness bar adjustment command is received or a change in ambient light is detected, a first temperature value of the terminal is determined.

In an optional example, when the terminal receives an instruction for adjusting a brightness bar of the terminal from a user, or when the terminal senses that current ambient light is changed, for example, the light is dark and dark, it may determine to trigger adjustment of a brightness value of the screen, and at this time, the terminal may obtain a temperature value of the terminal measured when the brightness value of the screen is triggered to be adjusted, where the temperature value measured in real time is the first temperature value.

In step 502, a first temperature control brightness value corresponding to the first temperature value is determined according to a preset temperature control curve.

In step 504, a desired brightness value of the screen is determined based on the brightness bar adjustment instruction or the changed ambient illumination.

In an alternative example, the desired brightness value may be determined based on a user's adjustment instruction for a brightness bar of the terminal. At this time, the desired brightness value is a brightness value that the user desires the terminal screen to display.

Specifically, the operating system of the terminal may monitor the state of the brightness bar of the terminal in real time, and when it is determined that the state of the brightness bar is changed, determine a brightness value corresponding to the changed state of the brightness bar, where the brightness value is the expected brightness value.

In another alternative example, the desired brightness value may be determined based on the changed ambient illumination. At this time, the desired brightness value is a brightness value adapted to the intensity of the ambient light.

Specifically, a light source sensor may be installed in the terminal. The operating system of the terminal can adjust the screen brightness value of the terminal according to the light intensity of the light source sensor.

For example, the correspondence between the exposure intensity and the screen brightness value may be as shown in table 1 below:

TABLE 1

Intensity of light sensing	Screen brightness value
		[0，200)	25
[200，400)	55
		[400，1000)	70
[1000，3000)	90
		[3000, infinity)	250

When the value of the light sensing intensity of the light source sensor is in a certain interval, the screen brightness value of the terminal is the screen brightness value corresponding to the interval. For example, when the light intensity is 800, it is determined that the value is in the interval of [400, 1000) according to the above table 1, and the corresponding screen brightness value is 70. The desired luminance value is 70.

The above description of the correspondence relationship between the light-sensitive intensity and the screen brightness value is only illustrative, and in practical applications, the user may modify the range and the number of the light-sensitive intervals and the screen brightness value corresponding to each interval arbitrarily based on practical situations, which is not limited by the present disclosure.

In step 506, it is determined whether the desired brightness value is greater than the first temperature control brightness value.

And when the adjusted desired brightness value is greater than the first temperature control brightness value, executing step 508a.

When the adjusted desired brightness value is less than or equal to the first temperature control brightness value, step 508b is executed.

In step 508a, the brightness value of the screen is adjusted to the first temperature control brightness value.

In step 508b, the brightness value of the screen is adjusted to the desired brightness value.

In one optional example, the first temperature control brightness value may be set to a maximum brightness value of the screen when a current brightness value of the screen is greater than the first temperature control brightness value. Therefore, the brightness value of the terminal screen cannot exceed the first temperature control brightness value in a subsequent period of time, and the temperature rise speed of the terminal is effectively inhibited. In this disclosure, no matter whether the terminal receives the brightness bar adjustment instruction or whether it detects that the ambient illumination changes, once the terminal detects that the current brightness value of the screen is greater than the first temperature control brightness value, which indicates that the current brightness value of the screen does not meet the requirement of temperature control adjustment, the terminal may set the first temperature control brightness value as the maximum brightness value of the screen at this time.

According to the screen brightness adjusting method provided by the embodiment of the disclosure, when the adjusted expected brightness value is greater than the first temperature control brightness value, the brightness value of the screen can be adjusted to the first temperature control brightness value. And when the adjusted expected brightness value is smaller than or equal to the first temperature control brightness value, adjusting the brightness value of the screen to the expected brightness value, thereby effectively controlling the temperature rise speed of the terminal.

Fig. 6 shows a threshold dimming method (the maximum brightness value of the screen is limited to 1000 nits when the temperature of the terminal reaches 35 c, 800 nits when the temperature of the terminal reaches 37 c, and 1000 nits when the temperature of the terminal is in the range of 35 c, 37 c). ) And the contrast graph is actually measured during the operation of the screen brightness adjusting method provided by the embodiment of the disclosure. As can be seen from the figure, the screen brightness adjusting method provided by the embodiment of the disclosure has a better control effect on the terminal temperature rise. And, the adjustment process for the terminal brightness is smoother, and the fluctuation of the brightness of the screen can be reduced.

While, for purposes of simplicity of explanation, the foregoing method embodiments have been described as a series of acts or combination of acts, it will be appreciated by those skilled in the art that the present disclosure is not limited by the order of acts, as some steps may, in accordance with the present disclosure, occur in other orders and concurrently.

Further, those skilled in the art should also appreciate that the embodiments described in the specification are exemplary embodiments and that acts and modules referred to are not necessarily required by the disclosure.

Corresponding to the embodiment of the application function implementation method, the disclosure also provides an embodiment of an application function implementation device and a corresponding terminal.
