However, as the material in the screen ages, the brightness actually output by the screen is lower than a certain brightness value after the terminal adjusts the screen to the brightness value. Correspondingly, along with the increase of the service life of the terminal screen, after the terminal automatically adjusts the screen brightness according to the external environment brightness and the brightness adjustment curve, the brightness output by the screen is different from the actually required brightness, so that the terminal cannot reasonably adjust the screen brightness according to the external environment brightness.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
For example, referring to fig. 1, a flowchart of an embodiment of a brightness compensation method according to the present application is shown, and the embodiment can be applied to a terminal with a screen, such as a mobile phone, a tablet computer, and the like. The method of the embodiment may include:
101, obtaining the parameter value of the physical parameter which currently affects the service life of the screen in the terminal.
It can be understood that, as the service life of the screen is reduced, the aging degree of the material in the screen is increased, so that after the terminal adjusts the brightness value of the output brightness of the screen, the actual output brightness of the screen is smaller than the brightness value of the required output currently set by the terminal, and thus, the output brightness of the screen cannot be matched with the current ambient brightness of the terminal, and the user experience is affected.
Accordingly, in the embodiment of the present application, the physical parameter that affects the service life of the screen may also be considered as a physical parameter that may reduce the output brightness of the screen.
For example, in a possible case, the physical parameter may be a total duration of the screen usage in the terminal from a time when the terminal is first used to a current time when the screen of the terminal is used, considering that the brightness of the screen output may be attenuated as the duration of the screen usage in the terminal increases. For example, taking the screen as an Organic Light-Emitting Diode (OLED) display screen, tests on the brightness attenuation ratio of OLEDs generated by different manufacturers show that the minimum brightness attenuation of the display screen formed by the OLEDs is 3% and the maximum brightness attenuation can reach 11% after the OLEDs are continuously lit for a long time of 240 hours, and the brightness attenuation of the screen is permanent, so that as the total duration of the screen of the terminal used by a user increases, the brightness output by the screen is lower and lower under the condition that the screen of the terminal outputs the same brightness value.
In another possible case, the physical parameter may be an average temperature of the screen during the total duration of the screen, considering that the higher the temperature of the screen, the higher the loss of the screen, and if the screen is at a higher temperature for a long time, the brightness of the screen output may be attenuated as the material loss in the screen increases. In this case, the temperature of the screen can be collected over different time periods, and the temperature value of the average temperature of the screen during the use of the screen can be calculated.
And 102, determining a target brightness adjustment relation of the screen according to the parameter value of the physical parameter.
And the target brightness adjustment relation is obtained by compensating the output brightness in the historical brightness adjustment relation of the screen according to the brightness compensation coefficient matched with the parameter value of the physical parameter. The historical brightness adjustment relationship is a brightness adjustment relationship according to which the terminal adjusts the screen brightness according to the ambient brightness before the current moment.
It should be noted that, in the embodiment of the present application, both the target brightness adjustment relationship and the historical brightness adjustment relationship are brightness adjustment relationships, and for the purpose of distinction only, the brightness adjustment relationship according to which the terminal adjusts the screen output brightness according to the ambient brightness before the current time is referred to as the historical brightness adjustment relationship; and the brightness adjustment relationship, which is determined at the current moment and according to which the terminal adjusts the screen brightness according to the environment brightness, is called a target brightness adjustment relationship.
And for any brightness adjustment relation, the brightness adjustment relation represents the brightness value required to be output by the screen of the terminal under different ambient brightness of the terminal. Specifically, the brightness adjustment relationship may include a mapping relationship between the ambient brightness and the output brightness of the screen. The output brightness of the screen is the screen brightness of the screen output. For example, the brightness adjustment relationship may be a so-called brightness adjustment curve or a brightness curve, for example, see fig. 2a, which shows a schematic diagram of a brightness curve representing the brightness adjustment relationship. In fig. 2a, the abscissa represents the brightness value of the ambient brightness of the terminal, and the ordinate represents the brightness value output by the screen of the terminal, so that when the ambient brightness of the terminal is different, the screen brightness required to be output by the terminal is different, and when the ambient brightness is lower, the screen brightness output by the terminal is relatively lower.
It can be understood that, after the terminal determines the ambient brightness of the environment where the terminal is currently located, the terminal determines the screen brightness required to be output by one screen according to the brightness adjustment relationship required by the current setting. However, as the aging degree of the screen increases, the actual brightness value of the screen brightness output by the screen of the terminal gradually decreases under the condition that the terminal sets the same screen brightness, so that the actual brightness value output by the screen cannot reach the screen brightness set by the terminal. In order to avoid that the actual screen brightness output by the screen cannot meet the requirement due to screen aging, in the embodiment of the application, the brightness compensation is performed on the screen brightness in the historical brightness adjustment relation according to the current time of the terminal according to the parameter value of the physical parameter which affects the screen aging degree, so that the screen brightness corresponding to the same ambient brightness in the historical brightness adjustment relation is increased, and the target brightness adjustment relation after the brightness compensation is obtained.
For the same ambient brightness, the brightness value of the screen brightness corresponding to the ambient brightness in the target brightness adjustment relationship is greater than the brightness value of the ambient brightness in the historical brightness adjustment relationship.
For example, still taking the brightness adjustment relationship as the brightness curve as an example, see fig. 2b, which shows a comparison diagram of the brightness curve and the brightness curve after brightness compensation, in this fig. 2b, the solid line represents the brightness curve without brightness compensation, in the embodiment of the present application, the brightness curve represented by the solid line may be regarded as the brightness curve characterizing the historical brightness adjustment relationship, and is labeled as the original brightness curve in fig. 2 b; the dotted line represents a luminance curve after luminance compensation, i.e., an automatically corrected luminance curve indicated in fig. 2b, and the dotted line represents a luminance curve corresponding to a luminance curve representing the target luminance adjustment relationship. Comparing the brightness curves represented by the dotted line and the solid line, it can be seen that after the original brightness curve is subjected to brightness compensation, the brightness value of the screen brightness corresponding to the same ambient brightness is increased, so that the screen brightness of the screen output is increased, the brightness value reduction of the screen output caused by screen aging is compensated, and the actual screen brightness of the screen output is matched with the ambient brightness.
When the output brightness of the historical brightness adjustment relationship is compensated, a brightness compensation coefficient can be determined according to the parameter value of the physical parameter, and then the output brightness in the historical brightness adjustment relationship is compensated according to the brightness compensation coefficient. When the physical parameter and the parameter value of the physical parameter are different, the brightness compensation coefficient matched with the parameter value of the physical parameter is also different.
In the embodiment of the present application, the physical parameters may include: one or more of the total usage time of the screen, the average temperature of the screen within the total usage time, and the like.
For example, taking the total use duration of the screen as an example, the larger the total use duration of the screen is, the larger the aging degree of the screen is, and the lower the brightness value of the screen brightness actually output by the screen is under the same output brightness, so that the larger the total use duration of the screen is, the larger the brightness compensation coefficient is, and what the specific brightness compensation coefficient is, the brightness attenuation of the screen can be tested in advance under different total use durations, and the brightness compensation coefficient can be determined according to the brightness attenuation.
As another example, taking the average temperature of the screen in the total usage period as an example, if the screen is at a high temperature for a long time, the degree of aging of the screen may be increased, and therefore, if the average temperature of the screen is higher in the total usage period of the screen, the required brightness compensation coefficient may be relatively large.
Of course, the brightness compensation coefficient of the output brightness of the screen is determined for the total usage duration of the integrated screen and the average temperature of the screen in the total usage duration, and the principles of compensating the brightness are also similar, which are not described herein again.
103, setting the target brightness adjustment relationship as a brightness adjustment relationship according to which the terminal adjusts the screen brightness according to the ambient brightness.
If so, the terminal can adjust the brightness adjustment relation according to the brightness adjustment relation of the screen brightness by the environment brightness from the historical brightness adjustment relation to the target brightness adjustment relation; or, through related setting, the terminal determines the target brightness adjustment relationship as a brightness adjustment relationship according to which the screen brightness is adjusted.
It can be understood that, after the target brightness adjustment relationship is set as the brightness adjustment relationship according to which the terminal adjusts the screen brightness according to the environment brightness, when it is detected that the environment brightness of the environment where the terminal is located changes, the output brightness required to be output by the screen of the terminal under the environment brightness of the environment where the terminal is currently located is determined according to the target brightness adjustment relationship, and the screen is controlled to output the screen brightness according to the output brightness.
Therefore, in the embodiment of the application, the terminal determines the target brightness adjustment relationship according to which the terminal adjusts the screen brightness according to the environment brightness at the current moment according to the parameter values of the physical parameters influencing the service life of the screen. Because the target brightness adjustment relation is obtained by compensating the output brightness in the brightness adjustment relation according to the brightness compensation coefficient matched with the parameter value of the physical parameter before the current moment of the screen, the brightness value of the output brightness in the target brightness adjustment relation is larger than the screen brightness required by the environment brightness of the current terminal, thus, although the screen of the terminal is aged due to the influence of the physical parameter, the screen brightness output by the screen of the terminal cannot reach the brightness value matched with the environment brightness of the current terminal, according to the target brightness adjustment relation, the screen can output the screen brightness with the output brightness required by the current environment brightness, so that the screen brightness actually output by the terminal can be matched with the current environment brightness, and the situation that the actual output brightness of the screen in the terminal is lower than the screen brightness required by the environment brightness of the current terminal is reduced, and then more reasonable screen brightness in the adjustment terminal has been realized.
It can be understood that, in the embodiment of the present application, in the process of using the terminal by the user, physical parameters such as the total use duration and the average temperature of the screen in the terminal are constantly changed, and when the physical parameters are changed, the brightness adjustment relationship suitable for the current terminal is also changed correspondingly. In order to adapt to the change of the physical parameters in the terminal, the terminal may periodically update the brightness adjustment relationship according to which the terminal adjusts the screen brightness, and correspondingly, the terminal may set a brightness compensation period, and if the brightness compensation period may be 240 hours, the brightness adjustment relationship is updated every 240 messages, so that when the current brightness compensation time is determined according to the preset brightness compensation period, the parameter value of the physical parameter currently affecting the service life of the screen in the terminal is obtained, and the target brightness adjustment relationship is re-determined based on the parameter value of the physical parameter.
Under the condition of periodically adjusting the brightness adjustment relationship, the historical brightness adjustment relationship in the embodiment of the present application may be a target brightness adjustment relationship determined last time before; the brightness adjustment relationship initially set for the terminal can also be used.
It is understood that, in the embodiment of the present application, there may be various ways to determine the target brightness adjustment relationship of the screen according to the parameter value of the physical parameter.
In one possible implementation, the output brightness in the historical brightness adjustment relationship may be compensated in real time to obtain the target brightness adjustment relationship. Specifically, the brightness compensation coefficient of the screen can be determined according to the parameter value of the physical parameter; then, based on the brightness compensation coefficient, the brightness value of the output brightness in the historical brightness adjustment relation of the screen is compensated, and the target brightness adjustment relation of the screen is obtained.
For example, a mapping relationship between parameter values of different physical parameters and brightness attenuation may be preset in the terminal, and according to the mapping relationship, the screen brightness attenuation degree corresponding to the parameter value of the currently acquired physical parameter may be determined. Since the required brightness compensation coefficients are different due to different brightness attenuation degrees, after the brightness attenuation degree is determined, the brightness compensation coefficient of the screen can be determined. The brightness compensation coefficient and the brightness attenuation degree can satisfy a preset functional relation. The mapping relation between the parameter value of the physical parameter and the brightness attenuation and the functional relation between the brightness attenuation degree and the brightness compensation coefficient can be determined by testing the brightness attenuation condition of the screen.
In yet another possible case, the terminal may predetermine a brightness adjustment relationship suitable for the terminal in the case of the parameter values of different physical parameters, and preset a plurality of brightness adjustment relationships suitable for the parameter values of different physical parameters. In this case, a target brightness adjustment relationship matching the parameter value of the physical parameter may be selected from a plurality of preset brightness adjustment relationships according to the currently acquired parameter value of the physical parameter. For example, a plurality of brightness curves may be preset, and different brightness curves are matched with the parameter values of the physical parameters, so that when the parameter values of the physical parameters change, the brightness curve according to which the terminal adjusts the screen brightness also changes.
The brightness adjustment relationship required to be matched with the parameter values of the different physical parameters in advance may also be obtained by determining a brightness compensation coefficient required by the terminal according to the attenuation degree of the screen of the terminal under different conditions of the parameter values of the physical parameters of the terminal, and compensating the historical brightness adjustment relationship of the terminal based on the brightness compensation coefficient, which is similar to the process of performing brightness compensation on the historical brightness adjustment relationship in real time, and is not repeated here.
In order to facilitate understanding of the method of the embodiment of the present application, the following description takes physical parameters as an example of the total duration of the screen in the terminal. For example, referring to fig. 3, which shows a flowchart of another embodiment of the brightness compensation method according to the present application, the method of the present embodiment may be applied to a terminal such as a mobile phone, a tablet computer, a notebook computer, and the like, and the method of the present embodiment may include:
301, when the current brightness compensation time is determined according to the preset brightness compensation period, obtaining the total use duration of the screen in the terminal at the current time.
Wherein, the length of the brightness compensation period can be set according to the requirement.
It is understood that, according to the brightness compensation period, the brightness compensation time may be determined periodically, for example, the brightness compensation period is 100 hours, and if the time length from the current time to the last brightness compensation time reaches 100 hours, it is determined that the current time reaches the brightness compensation time.
The total use duration of the screen can be understood as the accumulated total duration of the screen of the terminal in the lighting state in the process of using the terminal by the user.
It should be noted that, setting the brightness compensation period, and obtaining the total use duration of the screen at the current time when determining the current brightness compensation time based on the brightness compensation period is only one implementation manner, and in practical applications, the terminal may also determine the total use duration of the screen in real time.
302, detecting whether the total using time length exceeds a preset time length, if so, executing a step 303; if not, maintaining the brightness adjustment relation currently set in the terminal unchanged;
the preset time period may be set as required, for example, if it is assumed that the output brightness of the screen output is reduced after the total usage time period of the screen exceeds 240 hours, the preset time period may be set to 240 hours. If the total using time does not reach the preset time, the attenuation of the output brightness of the current screen can be considered to be small, and the brightness adjustment relation set by the terminal can not be compensated.
It can be understood that, if the total use duration of the screen exceeds the preset duration when a brightness compensation moment is reached, the subsequently obtained total use duration also necessarily exceeds the preset duration; moreover, when the total usage duration does not exceed the preset duration, the currently applicable target brightness adjustment relationship may also be determined based on the manner of the embodiment of the present application, so that the step S302 is only an optional step, and in practical applications, the step S302 may be selectively executed or not executed as needed.
303, when the total using duration exceeds a preset duration, determining a brightness compensation coefficient of a screen in the terminal according to the total using duration.
For example, a mapping relationship between the total usage time period and the brightness compensation coefficient may be preset, where each total usage time period corresponds to one brightness compensation coefficient in the mapping relationship.
For another example, brightness attenuation degrees corresponding to different total use durations and brightness compensation coefficients corresponding to different brightness attenuation degrees may be preset, so that after the brightness attenuation degree of the screen is determined according to the total use duration, a brightness compensation coefficient required by the screen at the current brightness attenuation degree may be determined.
The brightness compensation coefficient is used for compensating the output brightness of the screen in the brightness adjustment relation.
And 304, determining the historical brightness adjustment relation currently set by the terminal.
For example, the terminal queries a brightness adjustment relationship according to which the screen brightness is adjusted, which is set in the terminal, and takes the brightness adjustment relationship as a historical brightness adjustment relationship.
It can be understood that, if the terminal has not performed brightness compensation before the current time, the historical brightness adjustment relationship may be considered as an initial brightness adjustment relationship preset by the terminal, the initial brightness adjustment relationship may be fitted based on user experience, the terminal has an output brightness change relationship with the change of the external environment brightness and the output brightness required to be output by the screen, and the output brightness in the initial brightness adjustment relationship has not been subjected to brightness compensation. If the terminal has performed the brightness compensation operation before the current time, the historical brightness adjustment relationship may be regarded as the brightness adjustment relationship obtained by the brightness compensation last time before the current time.
It should be noted that, in this embodiment, a brightness adjustment relationship based on the currently set screen brightness of the terminal is taken as an example of the historical brightness adjustment relationship, and in practical applications, the terminal may also directly perform brightness compensation on the initial brightness adjustment relationship each time, that is, the step S303 may also be to obtain the initial brightness adjustment relationship set in the terminal, where the initial brightness adjustment relationship is the brightness adjustment relationship that is preset in the terminal and is not subjected to brightness compensation. Correspondingly, because the total use time lengths are different and the brightness compensation coefficients are different, the target brightness compensation relationship obtained after the brightness compensation is performed on the output brightness in the initial brightness adjustment relationship according to the brightness compensation coefficients is also different when the total use time lengths of the screens are different.
It is understood that the sequence of step 303 and step 304 is not limited to that shown in fig. 3, and in practical applications, the two steps may be performed simultaneously; step 304 may also be performed before step 303 is performed.
And 305, performing brightness compensation on the output brightness of the screen in the historical brightness adjustment relationship by using the brightness compensation coefficient to obtain a target brightness adjustment relationship.
For example, the output luminance of the screen in the history luminance adjustment relationship may be multiplied by the luminance compensation coefficient to compensate for the output luminance in the history luminance adjustment relationship. After the output brightness of the screen in the historical brightness adjustment relationship is subjected to brightness compensation, a new brightness adjustment relationship, that is, a target brightness adjustment relationship, is obtained.
It should be noted that, in this embodiment, an example is described in which a brightness compensation coefficient is determined in real time, and brightness compensation is performed on output brightness in a historical brightness adjustment relationship in real time based on the brightness compensation coefficient to obtain a target brightness adjustment relationship, but it can be understood that, if a brightness adjustment relationship according to which the terminal needs to adjust the screen brightness under different total use durations of the screen of the terminal is predetermined, and when the total use duration of the current screen is obtained, a target brightness adjustment relationship that needs to be matched with the total use duration of the current screen is determined, and the same is also applicable to this embodiment, and details are not repeated here.
And 306, setting the target brightness adjustment relationship as a brightness adjustment relationship according to which the screen brightness is adjusted in the terminal.
307, when detecting the change of the environment brightness of the environment where the terminal is located, determining the brightness value of the output brightness required to be output by the screen in the terminal based on the current environment brightness of the environment where the terminal is currently located and the target brightness adjustment relation.
308, controlling the screen output screen brightness according to the brightness value of the output brightness.
Here, the step 307 and the step 308 are optional steps, and the purpose thereof is only to facilitate understanding of the process of adjusting the screen brightness based on the target brightness adjustment relationship.
It can be understood that, in the embodiment of the present application, the description is given by taking the physical parameter as the total use time of the screen as an example, but it can be understood that, when the physical parameter is the average temperature of the terminal in the use process of the screen, the process of determining the target brightness adjustment relationship by the terminal is similar, and details are not repeated here.
For example, referring to fig. 4, which shows a flow chart of another embodiment of the brightness compensation method of the present application, the method of this embodiment may include:
401, when the current brightness compensation time is determined according to a preset brightness compensation period, acquiring the total use time of the screen in the terminal at the current time and the average temperature of the screen in the total use time.
In this embodiment, the parameter value of the physical parameter includes not only the value of the total duration of the current use of the screen, but also the average temperature of the screen within the total duration of the use. The aging degree of the screen can be better reflected through the total using time of the screen and the average temperature, so that the brightness compensation system can be more accurately determined, and the output brightness can be compensated.
402, when the total usage duration exceeds a preset duration, determining a brightness compensation coefficient of a screen in the terminal according to the total usage duration and the average temperature.
It can be understood that the total duration of use and the average temperature of the screen within the total duration of use both have an effect on the brightness attenuation of the screen, and therefore, the brightness attenuation degree of the screen at different total durations of use and different average temperatures can be tested in advance, so that the corresponding brightness compensation coefficient can be determined according to the brightness attenuation degree of the screen. For example, the corresponding relationship between the total usage time and the average temperature and the brightness compensation coefficient may be preset, so that after the total usage time and the average temperature are currently obtained, the currently required brightness compensation coefficient may be determined according to the corresponding relationship.
Similar to the embodiment of fig. 3, using the total duration exceeding the preset duration is an optional way, and even if the total duration does not exceed the preset duration, the brightness compensation can be performed by using the scheme of the embodiment of the present application.
And 403, determining a historical brightness adjusting relation according to which the screen brightness is adjusted according to the ambient brightness before the current moment of the terminal.
Similar to the previous embodiment, in this embodiment, the step S403 may also be replaced by determining an initial brightness adjustment relationship set in the terminal, and accordingly, the output brightness in the initial brightness adjustment relationship may be compensated according to the brightness compensation coefficient.
And 404, performing brightness compensation on the output brightness of the screen in the historical brightness adjustment relationship by using the brightness compensation coefficient to obtain a target brightness adjustment relationship.
It can be understood that the manner of determining the brightness adjustment relationship corresponding to different total usage durations and average temperatures in advance and determining the target brightness adjustment relationship corresponding to the currently obtained total usage duration and average temperature is also applicable to the embodiment.
405, the target brightness adjustment relationship is set as a brightness adjustment relationship according to which the screen brightness is adjusted in the terminal.
