Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not paid
Embodiment, belongs to the scope of protection of the invention.
Such as, referring to Fig. 1, it illustrates a kind of schematic flow sheet of luminance compensation method one embodiment of the application, this reality
Apply example and can apply to the terminal with screen, such as mobile phone, tablet personal computer.The method of the present embodiment can include：
101, obtain the parameter value of the physical parameter of the service life of screen in current influence terminal.
It is understood that with the reduction of screen service life, the degree of aging aggravation of material in screen, so, when
After the brightness value of the output brightness of terminal adjustment screen, it is required that the actual output brightness of screen can currently be set less than terminal
The brightness value of output, so, will cause screen output brightness can not be presently in ambient brightness with terminal and match, have influence on use
Experience at family.
Accordingly, in the embodiment of the present application, the physical parameter of the service life of screen is had influence on it is also assumed that being meeting
Reduce the physical parameter that screen exports brightness.
Such as, in the case of one kind is possible, it is contemplated that as screen uses the increase of duration in terminal, it is bright that screen is exported
Degree can decay, therefore, the physical parameter can in the current time terminal screen use total duration, wherein, this makes
Referred to total duration since being first used terminal, to the total duration that is used of screen of the current time terminal.For example, with
Screen be Organic Light Emitting Diode (Organic Light-Emitting Diode, OLED) display screen exemplified by, by not
The OLED generated with manufacturer brightness decay, which is compared, carries out test discovery, is uninterruptedly lighted by the long-time up to 240 hours,
The brightness minimal attenuation for the display screen that OLED is constituted is 3%, and brightness decay it is larger can reach 11%, and screen is bright
It is permanent that degree is decayed, so, defeated in the screen of setting terminal with the increase of the total duration of the screen of user's using terminal
In the case of going out same brightness value, the brightness of screen output can be more and more lower.
In the case of alternatively possible, it is contemplated that during using terminal, the temperature of screen is higher, to screen
Loss is higher, if screen is in higher temperature for a long time, as spillage of material aggravates in screen, and the brightness of screen output also can
It has been decayed that, therefore, the physical parameter can also be to be used in screen in total duration, the mean temperature of the screen.In this kind of feelings
Under condition, the temperature in screen different time sections can be gathered, and is calculated during screen use, the mean temperature of the screen
Temperature value.
102, according to the parameter value of the physical parameter, determine the object brightness adjustment relation of screen.
Wherein, object brightness adjustment relation is the luminance compensation coefficient that foundation is matched with the parameter value of the physical parameter, right
Output brightness in historical light's adjustment relation of the screen compensates what is obtained.When historical light adjustment relation is current
The terminal adjusts the brightness adjustment relation of screen intensity institute foundation according to ambient brightness before quarter.
It should be noted that object brightness adjustment relation and historical light's adjustment relation are all in the embodiment of the present application
A kind of brightness adjustment relation, just to distinguish, screen output brightness is adjusted by terminal before current time according to ambient brightness
The brightness adjustment relation of institute's foundation is referred to as historical light's adjustment relation；And the terminal for determining current time is according to ambient brightness
The brightness adjustment relation of adjustment screen intensity institute foundation is referred to as object brightness adjustment relation.
Wherein, for any one brightness adjustment relation, the brightness adjustment relation is characterized is in difference in terminal
Ambient brightness under, the brightness value of output needed for the screen of the terminal.Specifically, the brightness adjustment relation can be bright including environment
Mapping relations between degree and the output brightness of screen.Wherein, i.e. screen output brightness screen output screen intensity.
Such as, the brightness adjustment relation can be the brightness adjustment curve or brightness curve being commonly called as, and e.g., referring to Fig. 2 a, it illustrates table
Levy the schematic diagram of the brightness curve of brightness adjustment relation.In fig. 2 a, abscissa illustrates the bright of the ambient brightness residing for terminal
Angle value, and ordinate illustrates the brightness value that the screen of terminal is exported, it is seen then that when the ambient brightness residing for terminal is different,
The screen intensity of output is also different needed for terminal, moreover, when ambient brightness is relatively low, and the screen intensity that terminal is exported is also relatively
It is low.
It is understood that after the ambient brightness that terminal determines present terminal local environment, terminal meeting basis is worked as
The brightness adjustment relation of the required foundation of preceding setting, determines the screen intensity of output needed for a screen.However as screen
Degree of aging increase, in the case of the same screen intensity of terminal profile, the screen intensity that the screen of terminal is exported
Intrinsic brilliance value but gradually reduce so that the brightness value of screen reality output is unable to reach the screen intensity set by terminal.
In order to avoid due to screen aging, and cause the screen intensity of screen reality output can not meet demand, in the embodiment of the present application
In, according to the parameter value of the physical parameter of influence screen aging degree, the history to institute's foundation before terminal current time is bright
The screen intensity spent in adjustment relation carries out luminance compensation so that same ambient brightness institute is right in historical light's adjustment relation
The screen intensity increase answered, that is, obtain the adjustment relation of the object brightness after luminance compensation.
Wherein, for same ambient brightness, the corresponding screen of the ambient brightness in the object brightness adjustment relation
The brightness value of brightness, more than the brightness value of the ambient brightness in historical light's adjustment relation.
Such as, still it is introduced so that brightness adjustment relation is brightness curve as an example, it is e.g., bent it illustrates brightness referring to Fig. 2 b
The contrast schematic diagram of line and the brightness curve after luminance compensation, in Fig. 2 b, solid line represents that the brightness without luminance compensation is bent
Line, in the embodiment of the present application, the brightness curve represented by solid line, which is considered, characterizes the bright of historical light's adjustment relation
Write music line, such as Fig. 2 b acceptances of the bid are shown as original brightness curve；Dotted line is represented in the brightness curve after luminance compensation, i.e. Fig. 2 b
Brightness curve after the automatic correction marked, the brightness curve that the dotted line is represented adjusts the bright of relation equivalent to object brightness is characterized
Write music line.Contrast dotted line can be seen that by carrying out brightness to original brightness curve with the brightness curve that solid line is each characterized
After compensation, the brightness value increase of the screen intensity corresponding to same ambient brightness, so as to increase the screen of screen output
Brightness, to make up the luminance-value reduction for causing screen to export due to screen aging so that the screen intensity of screen reality output
Match with ambient brightness.
Wherein, can be first according to the physical parameter when the output brightness that relation is adjusted to historical light is compensated
Parameter value determines luminance compensation coefficient, and then the output brightness in historical light's adjustment relation is carried out according to luminance compensation coefficient
Compensation.When the parameter value of physical parameter and physical parameter is different, the luminance compensation that the parameter value of the physical parameter is matched
Coefficient would also vary from.
In the embodiment of the present application, the physical parameter can include：The use total duration of screen, screen this using it is total when
One or more in the parameters such as the mean temperature in length.
Such as, by taking the use total duration of screen as an example, what screen was used uses total duration bigger, and the degree of aging of screen is got over
Greatly, under same output brightness, the brightness value of the screen intensity of screen reality output is lower, therefore, and the use total duration of screen is got over
Greatly, luminance compensation coefficient is also bigger, specific luminance compensation coefficient be it is how many, can in advance under different use total durations,
The brightness decay of test screen, and luminance compensation coefficient is determined according to brightness decay.
And for example, by exemplified by the mean temperature using screen in total duration, if screen is under high temperature for a long time, screen
Degree of aging can aggravate, therefore, if this used in screen is used in total duration, the mean temperature of screen is higher, required
Luminance compensation coefficient also can be relatively large.
Certainly, for comprehensive screen use total duration and screen at this using the mean temperature in total duration, it is determined that
The luminance compensation coefficient of the output brightness of screen, and the principle compensated to brightness are also similar, will not be repeated here.
103, the object brightness is adjusted into relation and is set to terminal according to the bright of ambient brightness adjustment screen intensity institute foundation
Spend adjustment relation.
Such as, the brightness adjustment relation that can adjust screen intensity institute foundation according to ambient brightness with terminal is adjusted by historical light
Relation is adjusted to object brightness adjustment relation；Either, by correlation setting, to cause terminal adjusts the object brightness to close
System is defined as the brightness adjustment relation of foundation needed for adjusting screen intensity.
It is understood that object brightness adjustment relation is being set into terminal according to ambient brightness adjustment screen intensity institute
After the brightness adjustment relation of foundation, when the ambient brightness for detecting terminal local environment changes, and it is bright according to the target
Adjustment relation is spent, it is determined that be presently in terminal under the ambient brightness of environment, the output brightness of output needed for the screen of terminal, and
Screen is controlled according to the output brightness output screen brightness.
It can be seen that, in the embodiment of the present application, terminal can according to influence screen service life physical parameter parameter value, really
Determine the object brightness adjustment relation that current time terminal adjusts screen intensity institute foundation according to ambient brightness.Due to the object brightness
Adjustment relation is according to the luminance compensation coefficient matched with the parameter value of the physical parameter, to institute before the current time of the screen
Output brightness in the brightness adjustment relation of foundation compensates what is obtained, therefore the output in the object brightness adjustment relation is bright
The brightness value of degree is more than the screen intensity needed for the ambient brightness of present terminal local environment, so, although due to physical parameter
Influence cause the screen aging of terminal, the screen intensity for causing the screen of terminal to export do not reach and present terminal local environment
The brightness value that matches of ambient brightness, but adjust relation according to the object brightness, screen can be caused with higher than working as front ring
Output brightness needed for the brightness of border carrys out output screen brightness, so that the screen intensity of terminal reality output can be current with this
Ambient brightness matches, and reduces the actual output brightness of screen in terminal and is less than needed for the ambient brightness that terminal is presently in
The situation of screen intensity, and then realize screen intensity in more rational adjustment terminal.
It is understood that in the embodiment of the present application, during user's using terminal, the use of screen in terminal
The physical parameter such as total duration and mean temperature all can constantly change, and when these physical parameters change, currently
The brightness adjustment relation that terminal is adapted to also can accordingly change.In order to adapt to the change of the physical parameter of these in terminal
Change, terminal can periodically update the brightness adjustment relation of terminal adjustment screen intensity institute foundation, and accordingly, terminal can be set
The luminance compensation cycle is put, such as luminance compensation cycle can be 240 hours, then closed every brightness adjustment of 240 information updating
System, so, when according to the default luminance compensation cycle, determining the current arrival luminance compensation moment, then can obtain current shadow
The parameter value of the physical parameter of the service life of screen in terminal is rung, so that the parameter value based on the physical parameter redefines mesh
Mark brightness adjustment relation.
In the case where periodicity adjusts the brightness adjustment relation, the historical light of the embodiment of the present application adjustment relation can be with
Relation is adjusted for the current object brightness determined last before；The brightness adjustment relation that can also be set for terminal initial.
It is understood that in the embodiment of the present application, according to the parameter value of the physical parameter, determining that the target of screen is bright
The mode of degree adjustment relation can have a variety of.
In a kind of possible implementation, the output brightness in historical light's adjustment relation can be mended in real time
Repay, to obtain object brightness adjustment relation.Specifically, parameter value that can be according to physical parameter, determines the brightness of the screen
Penalty coefficient；Then, based on the luminance compensation coefficient, the brightness to the output brightness in historical light's adjustment relation of the screen
Value is compensated, and obtains the object brightness adjustment relation of the screen.
Such as, it can be reflected in terminal with the parameter value of preset different physical parameter and the mapping relations of brightness decay according to this
Penetrate relation, it may be determined that the screen intensity dough softening corresponding to the parameter value of the physical parameter currently got.Because difference is bright
The dough softening is spent, required luminance compensation coefficient is different, after brightness decay degree is determined, it may be determined that go out the brightness of the screen
Penalty coefficient.Wherein, functional relation set in advance can be met between luminance compensation coefficient and brightness decay degree.Wherein, thing
Manage the mapping relations between the parameter value of parameter and brightness decay, and the function between brightness decay degree and luminance compensation coefficient
Relation can be tested to determine according to the brightness decay situation to screen.
In the case of another is possible, terminal can predefine out the situation in the parameter value of different physical
Under, the brightness adjustment relation that the terminal is adapted to, and the brightness adjustment pass of the parameter value of preset a variety of suitable different physicals
System.In that case, parameter value that can be according to the physical parameter currently got, from preset multiple brightness adjustment relations
In, select the object brightness adjustment relation matched with the parameter value of the physical parameter.Such as, can with preset multiple brightness curves,
Different brightness curves and the parameter value of physical parameter match, so, when the parameter value variation of physical parameter, terminal adjustment screen
The brightness curve of foundation can also change needed for curtain brightness.
Wherein, when the brightness adjustment relation matched needed for the parameter value of advance different physical, equally may be used
Be according to the parameter value of the physical parameter of terminal in varied situations, the attenuation degree of the screen of the terminal determines terminal
Required luminance compensation coefficient, and based on luminance compensation coefficient, historical light's adjustment relation to terminal compensates what is obtained,
The process is similar to the process for adjusting relation progress luminance compensation to historical light in real time, will not be repeated here.
Method for the ease of understanding the embodiment of the present application, below using physical parameter as terminal in screen use total duration
Exemplified by be introduced.Such as, referring to Fig. 3, it illustrates a kind of signal of the flow of another embodiment of luminance compensation method of the application
Figure, the method for the present embodiment can apply to the terminals such as mobile phone, tablet personal computer, notebook computer, and the method for the present embodiment can be with
Including：
301, when according to the default luminance compensation cycle, determining the current arrival luminance compensation moment, when obtaining current
Carve the use total duration of screen in terminal.
Wherein, the length in the luminance compensation cycle can be set as needed.
It is understood that according to the luminance compensation cycle, the luminance compensation moment can be periodically determined, it is e.g., bright
It is 100 hours to spend compensation cycle, if the duration at distance last luminance compensation moment at current time reaches 100 hours, really
Determine the arrival luminance compensation moment at current time.
Wherein, the use total duration of screen is appreciated that during user's using terminal, and the screen of terminal is in point
The total time duration of bright state.
It should be noted that the setting luminance compensation cycle, and determining that current arrival brightness is mended based on the luminance compensation cycle
When repaying the moment, the use total duration for obtaining current time screen is only a kind of implementation, and in actual applications, terminal also may be used
To determine the use total duration of screen in real time.
302, detect whether this exceedes preset duration using total duration, if it is, performing step 303；If it is not, then dimension
Hold current set brightness adjustment relation in terminal constant；
Wherein, the preset duration can be set as needed, such as, it is assumed that the use total duration of screen more than 240 hours it
Afterwards, the situation of the output luminance-reduction of screen output is just displayed, then the preset duration could be arranged to 240 hours.Such as
Fruit does not reach the preset duration using total duration, then, can not be right it is considered that the decay of the output brightness of current screen is smaller
Brightness adjustment relation set by terminal is compensated.
If it is understood that when reaching a luminance compensation moment, the use total duration of the screen is default more than this
Duration, then the use total duration subsequently got also necessarily exceedes the preset duration；Moreover, pre- being no more than using total duration
If during duration, the object brightness adjustment relation being currently applicable can be similarly determined based on the mode of the embodiment of the present application, therefore,
Step S302 is only an optional step, in actual applications, can select to perform or do not perform the step as needed
Rapid S302.
303, when this exceedes preset duration using total duration, total duration is used according to this, the bright of screen in terminal is determined
Spend penalty coefficient.
Such as, can with the mapping relations between preset use total duration and luminance compensation coefficient, wherein, in the mapping relations
In, it is each to correspond to a luminance compensation coefficient using total duration.
And for example, can be right with the preset different brightness decay degree using corresponding to total duration, and different brightness decay degree institutes
The luminance compensation coefficient answered, so, after the brightness decay degree of screen is determined using total duration according to this, it may be determined that should
Luminance compensation coefficient of the screen needed under current brightness decay degree.
Wherein, the output brightness that the luminance compensation coefficient is used for screen in brightness adjustment relation is compensated.
304, determine historical light's adjustment relation that terminal is currently set.
Such as, the brightness adjustment relation of the adjustment screen intensity institute foundation set in terminal inquiry terminal, by the brightness adjustment
Relation adjusts relation as historical light.
If it is understood that before current time, terminal was not carried out luminance compensation, then the historical light adjusts
Relation may be considered the original intensity adjustment relation of terminal preset, and original intensity adjustment relation can be the body based on user
Test what is fitted, the terminal is with the change of external environment brightness, the output brightness variation relation of output needed for screen, and this is first
Output brightness in beginning brightness adjustment relation is without luminance compensation.If before current time, terminal performed luminance compensation
Operation, then historical light adjustment relation is the last before being then considered current time passes through what luminance compensation was obtained
Brightness adjustment relation.
It should be noted that being the brightness tune of the adjustment screen intensity institute foundation currently set with terminal in the present embodiment
Whole relation exemplified by historical light's adjustment relation as illustrating, in actual applications, and terminal can also be every time directly to initial
Brightness adjustment relation carries out luminance compensation, i.e. step S303 can also close to obtain the original intensity set in terminal adjustment
System, original intensity adjustment relation is preset, and the brightness adjustment relation without luminance compensation in terminal.Accordingly, due to
Different using total duration, luminance compensation coefficient is different, therefore, when the difference of screen is using total duration, according to luminance compensation system
Output brightness in several adjustment relations to original intensity carry out after luminance compensation obtained by object brightness compensation relationship not yet
Together.
It is understood that the order of the step 303 and step 304 is not limited to shown in Fig. 3, in actual applications, can
To perform the two steps simultaneously；Can also perform the step 304 before step 303 is performed.
305, using the luminance compensation coefficient, the output brightness to screen in historical light's adjustment relation carries out brightness benefit
Repay, to obtain object brightness adjustment relation.
Such as, can be by the output brightness of the screen in historical light's adjustment relation and the luminance compensation multiplication, with right
Output brightness in historical light's adjustment relation is compensated.Wherein, by the screen in historical light's adjustment relation
Export after brightness progress luminance compensation, a new brightness adjustment relation, i.e. object brightness adjustment relation can be obtained.
It should be noted that being to determine luminance compensation coefficient in real time, and based on luminance compensation coefficient in the present embodiment
Luminance compensation is carried out to the output brightness in historical light's adjustment relation in real time, carried out exemplified by obtaining object brightness adjustment relation
Introduce, but it is understood that, if predefined out in the case where the difference of the screen of terminal is using total duration, terminal adjustment screen
The brightness adjustment relation of foundation needed for curtain brightness, and when getting the use total duration of current screen, determine current screen
Relation is adjusted using the object brightness matched needed for total duration, the present embodiment is applied equally to, will not be repeated here.
306, the object brightness is adjusted into the brightness adjustment relation that relation is set to adjust screen intensity institute foundation in terminal.
307, when the ambient brightness for detecting terminal local environment changes, work as front ring based on what terminal was presently in environment
Border brightness and object brightness adjustment relation, determine the brightness value of the output brightness of output needed for screen in terminal.
308, according to the brightness value of the output brightness, control screen output screen brightness.
Wherein, the step 307 and step 308 are optional step, and its purpose is intended merely to facilitate understanding and is based on the target
Brightness adjustment relation, adjusts the process of screen intensity.
It is understood that in the embodiment of the present application, being carried out so that physical parameter is the use total duration of screen as an example
Introduce, but it is understood that, when physical parameter be terminal in the mean temperature during screen use when, terminal determines mesh
The process for marking brightness adjustment relation is similar, will not be repeated here.
Below using the use total duration of physical parameter including screen and this using screen in total duration mean temperature as
Example is introduced, e.g., referring to Fig. 4, it illustrates a kind of schematic flow sheet of another embodiment of luminance compensation method of the application,
The method of the present embodiment can include：
401, when according to the default luminance compensation cycle, determining the current arrival luminance compensation moment, when obtaining current
The use total duration and the screen for carving screen in terminal use the mean temperature in total duration at this.
In the present embodiment, the parameter value of physical parameter not only includes the value of the use total duration of screen currently, also wraps
Include screen and use the mean temperature in total duration at this., can be more preferable by the use total duration and the mean temperature of screen
Reflect the degree of aging of screen, so as to be conducive to more accurately determining luminance compensation system and output brightness is carried out
Compensation.
402, when this exceedes preset duration using total duration, total duration and the mean temperature are used according to this, it is determined that
The luminance compensation coefficient of screen in terminal.
It is understood that using total duration and in the mean temperature using screen in total duration, can be to screen
Brightness decay produces influence, therefore, it can test in advance under different use total durations and different mean temperatures, the screen
