First embodiment
The present embodiment provides the screen calibration method of a kind of electronic equipment, can be applied to such as Fig. 1 or electricity shown in Fig. 3
Sub- equipment, and for being calibrated to the screen of electronic equipment.Refering to Fig. 5, the method may include following steps:
S110: the display brightness of each display area is obtained.
The display brightness of display area refers to: in the case where display area is in bright screen state, the real-time display of display area is bright
Degree.The display brightness of display area can for example be obtained in the following ways: light being arranged below flexible display screen and passes
Sensor obtains the display brightness of display area by light sensor.In some embodiments, the display brightness of display area
Image can also be imaged and obtained to display area by external camera, obtain display by carrying out processing to image
The display brightness in region.Alternatively, obtaining the display brightness of display area by external light sensor.
In some embodiments, it can be obtained separately or together when multiple display areas expand into flat state
The display brightness of each display area.When obtaining the display brightness of display area, can be shown in multiple display areas identical
Standard specimen page, standard specimen page can be monochromatic specimen page, such as: the monochrome specimen page such as uniform red, blue, green or white.
Display brightness is obtained by monochromatic standard specimen page, the acquisition condition of the display brightness of each display area can be made to keep one
It causes, display brightness obtains difference caused by excluding the COLOR COMPOSITION THROUGH DISTRIBUTION because of specimen page, is more advantageous to subsequent carry out screen calibration.
In some embodiments, the display brightness of each display area itself can also have differences, as shown in fig. 6, the
There is also display brightness differences for one display area 31 itself, can be at this time when obtaining the display brightness of the first display area 31
By obtaining display brightness of the average brightness of the first display area 31 as the first display area.It puts down the first display area 31
Equal brightness can be the average value of the display brightness of each point in the first display area.In some embodiments, each viewing area
The measured value of the display brightness in domain can store in the memory of electronic equipment, and for the display brightness to each display area
Value variation tendency is analyzed.
Such as: the brightness value of the first display area is L1, and the brightness value of the second display area is L2, third display area
Brightness value is L3 ....
S120: calculating the dispersion degree of the brightness value of the multiple display area, judges whether dispersion degree is greater than or waits
In discrete threshold values.
Dispersion degree refers to the difference degree between the brightness value of each display area, dispersion degree can by it is very poor,
Variance, interquartile-range IQR, standard deviation (Standard Deviation), mean difference (Mean Deviation), the coefficient of variation
Parameters such as (Coefficient of Variation, CV) are characterized, it can by any of the above-described parameter or combinations thereof conduct
Dispersion degree value.Wherein variance refers to the square root of the arithmetic average of each display brightness value and the difference square of its average.Respectively
The variance of the brightness value of a display area
Wherein, r is the average value of the display brightness of each display area, i.e., the average display brightness of each display area.Li is
Refer to that the display brightness of each display area, N represent the number of display area.Variance is bigger, and it is more discrete to represent data, i.e., each display
Difference between the brightness value in region is bigger.
Dispersion degree value generates variation with the variation of the display brightness of each display area, therefore the display of each display area is bright
The dispersion degree of degree can update at any time.Simultaneously when obtaining the dispersion degree of brightness value of multiple display areas, also obtain each
The average value r of the display brightness of display area.
It is appreciated that in some embodiments it is possible to characterize dispersion degree using very poor, it is very poor be equal to it is each aobvious
Show in the brightness value in region, the difference between the maximum value of brightness value and the minimum value of brightness value.It is very poor bigger, dispersion degree
Bigger, very poor smaller, then dispersion degree is smaller.
S130: when the dispersion degree is greater than or equal to discrete threshold values, the driving electricity of the multiple display area is adjusted
Stream, until the dispersion degree is less than or equal to the discrete threshold values, using the driving current after adjusting as calibration electric current.
Driving current refers to current value of the display area in display.By be arranged discrete threshold values, and to dispersion degree with
Discrete threshold values are compared judgement, can control screening process, are only greater than or equal in dispersion degree discrete
Calibration process is just carried out when threshold value.It avoids electronic equipment from frequently calibrating to screen, on the one hand can save and be calibrated
On the other hand the power consumption for the treatment of process will not excessively occupy the time of user.
Discrete threshold values can be preset, and be adjusted according to the degree that user generates the collimation error.Such as when discrete
When difference between degree and discrete threshold values is 1, user can perceive display effect difference, at this time can be by discrete threshold values
It is set as 0.5-2.In some embodiments, user can be with self-setting discrete threshold values, to meet itself use demand.
When dispersion degree is greater than or equal to discrete threshold values, illustrate that the display brightness of each display area is more discrete, therefore
Differing greatly between the display brightness of each display area, the display brightness that user easily perceives between each display area are poor
It is different, cause discomfort, the display brightness to each display area is just needed to be adjusted calibration at this time.The mode of calibration is to pass through adjusting
The driving current of each display area, and then display brightness is raised and lowered to carry out.
It is understood that the driving current for adjusting multiple display areas not necessarily adjusts the drive of all display areas
Streaming current.By taking electronic equipment shown in FIG. 1 as an example, Fig. 6 shows electronic equipment and carries out one of calibration process process interface
Figure.In some embodiments, the driving current that can only adjust a display area or two display areas, in some implementations
In mode, the driving current of adjustable all display areas.As long as guaranteeing that the display for meeting each display area after adjusting is bright
The dispersion degree of degree is no more than discrete threshold values.
In some embodiments, when adjusting the driving current of display area, can by the uniform velocity or it is non-at the uniform velocity in a manner of by
Edge up high or reduction driving current.The regulative mode that great-jump-forward can also be used, i.e., in the driving current for adjusting display area
When, progress is stepped to be raised and lowered, and the regulating effect of this regulative mode can be more quick.In some embodiments,
The amplitude of accommodation being raised and lowered can be preset, when adjusting, is adjusted by the preset amplitude of accommodation.When adjusting, it can adopt
It is carried out with the mode for adjusting multiple display areas simultaneously, such as the driving current of all display areas is adjusted simultaneously.
It can also successively be adjusted, i.e., after the completion of a display area is adjusted, then adjust next display area.
It, can be using the driving current after adjusting as school when adjusting to updated dispersion degree no more than discrete threshold values
Quasi- electric current is stored.It is understood that calibration electric current can store and locally be stored in server in electronic equipment.
As an example, it is illustrated by taking electronic equipment as shown in Figure 3 as an example.First display area 31, second is aobvious
The original display brightness for showing region 32 and third display area 33 is respectively L11, L21 and L31, and corresponding driving current is
I11, I21 and I31.After adjustment, the first display area 31, the second display area 32 and third display area 33 display brightness
Respectively L12, L22 and L32, the corresponding driving current of display brightness adjusted are I21, I22 and I32.After adjusting at this time
Driving current I21, I22 and I32 be as calibration electric current storage.
It is understood that all displays might not be adjusted due to when adjusting the driving current of multiple display areas
The driving current in region, therefore in some embodiments, I11 may be identical as I21, and I21 may be identical as I22, and I31 can also
It can be identical as I32.
S140: the multiple display area is shown with each corresponding calibration electric current driving in display area.
When using electronic equipment next time, it can the calibration current value of storage is used to show multiple displays as driving current
Region, the dispersion degree of the display brightness of display area each in this way are the state no more than discrete threshold values, and user will not perceive
Difference between the display brightness of each display area.
The present embodiment is obtained by the display brightness of the different display areas to electronic equipment, calculates each display area
Display brightness between dispersion degree value, and dispersion degree be greater than or equal to discrete threshold values when, calibration behaviour is carried out to screen
Make, and then the display brightness of each display area is adjusted, guarantees that the difference of the display brightness of each display area is smaller.Together
When, due to not needing that dispersion degree is controlled to obtain to very little, thus it is little to the adjustment amount of the driving current of each display area,
The service life of each display area is influenced smaller.
Second embodiment
The present embodiment provides the screen calibration method of a kind of electronic equipment, can be applied to such as Fig. 1 or electricity shown in Fig. 3
Sub- equipment, and for being calibrated to the screen of electronic equipment.Refering to Fig. 7, the method may include following steps:
S210: standard specimen page is shown in each display area with same driving current, obtains each viewing area
The brightness value in domain.
Wherein, standard specimen page refers to that the dedicated specimen page for carrying out display brightness acquisition, standard specimen page can be monochromatic sample
It opens and is also possible to polychrome specimen page.It drives all display areas to be shown with identical driving current, and shows identical mark
The display brightness value of quasi- specimen page, each display area got in this way can be more objective, and the brightness value acquired is as aobvious
Show that the self diathesis in region is related, can be more advantageous to whether evaluation flexible display screen is calibrated.
S220: calculating the dispersion degree of the brightness value of the multiple display area, judges whether dispersion degree is greater than or waits
In discrete threshold values.
S230: when the dispersion degree is greater than or equal to discrete threshold values, the maximum display area of brightness value is reduced
Driving current, until the display brightness of the maximum display area of brightness value is average bright not less than the multiple display area
Degree.
When dispersion degree is greater than or equal to discrete threshold values, illustrates that the brightness value of each display area is more discrete, lead at this time
The brightness value with the display area of the average value r disparity of the brightness value of each display area is overregulated, can faster be reached
To the purpose for reducing dispersion degree.The brightness value that the maximum display area of brightness value can be reduced at this time, can also be improved bright
The brightness value of the smallest display area of angle value.Since flexible display screen has the speciality of aging, with the growth for using the time, meeting
Gradually aging in turn results in the decline of display effect.Therefore by reducing the brightness value of the display area of high luminance values, can subtract
The degree of aging of the small maximum display area of brightness value, prolongs its service life.
When dispersion degree is greater than or equal to discrete threshold values, the driving of the reduction maximum display area of brightness value first is electric
Stream.I.e. by reducing the driving current of the maximum display area of brightness value, the brightness value of the maximum display area of brightness value is reduced.
At this point, the dispersion degree of the brightness value of the multiple display area can reduce, and then dispersion degree may be adjusted to be no more than
Discrete threshold values.
During reducing the brightness value of the maximum display area of brightness value, it is maximum described to be at most adjusted to brightness value
The display brightness of display area is not less than the average brightness of the multiple display area.Reducing the maximum viewing area of brightness value
When the driving current in domain, the brightness value for being at most adjusted to the display area is identical as the average brightness r of multiple display areas, if
Continuation reduce down, will lead to the display area display brightness variation it is excessive, cause the display area driving current and its
The driving current of his display area has biggish gap, is unfavorable for maintaining calibration result for a long time, may cause flexible display screen
It needs often to calibrate.
It is understood that when adjusting the driving current of the maximum display area of brightness value, it is adjustable extremely
The brightness value of display area is greater than the average brightness of all display areas.It is adjusted to the maximum display area of brightness value
Display brightness is equal to before the average brightness of all display areas, can stop adjusting at any time.It in some embodiments, can be with
The amplitude of adjusting is preset, such as brightness value amplitude of accommodation threshold value f1 can be set, is adjusting the maximum viewing area of brightness value
When the driving current in domain, so that the brightness value knots modification of the display area is no more than brightness value amplitude of accommodation threshold value f1, brightness value
Amplitude of accommodation threshold value f1 can preset or be customized by the user.
S240: the dispersion degree of the brightness value of the multiple display area is reacquired.
It is understood that reduce the maximum display area of brightness value brightness value during, dispersion degree value by
It is decrescence small, be likely to occur at this time dispersion degree value be reduced to it is still big no more than the situation of discrete threshold values or dispersion degree value
In or equal to discrete threshold values.It, can be with the multiple displays of real-time update when adjusting the driving current of the maximum display area of brightness value
The dispersion degree of the brightness value in region.
S250: whether the updated dispersion degree of detection is more than the discrete threshold values.
When detecting that updated dispersion degree is more than discrete threshold values, step S260 is executed, if detecting updated
When dispersion degree is less than discrete threshold values, step S270 is executed.
S260: the driving current of the remaining display area is adjusted.
The driving current for adjusting remaining display area, which refers to, adjusts other in addition to the maximum display area of brightness value
The driving current of display area, so that dispersion degree is no more than discrete threshold values.Adjusting method at this time can be the same as step above-mentioned
Rapid S130.In some embodiments, adjusting method can also refer to step S230, i.e., using in the remaining display area of reduction
The mode of driving current of the maximum display area of brightness value carry out.
In the present embodiment, refering to Fig. 8, step S260 can be carried out in the following manner.
Step S261: increasing the driving current of the smallest display area of brightness value, until brightness value is the smallest described aobvious
Show that the display brightness in region is not higher than the average brightness of the multiple display area.
When dispersion degree is still greater than or is equal to discrete threshold values, it is the smallest to increase brightness value in remaining display area first
The driving current of display area.I.e. by improving the driving current of the smallest display area of brightness value, it is maximum to improve brightness value
The brightness value of display area.At this point, the dispersion degree of the brightness value of the multiple display area can equally reduce, and then may incite somebody to action
Dispersion degree is adjusted to be no more than discrete threshold values.
During reducing the brightness value of the maximum display area of brightness value, it is the smallest described to be at most adjusted to brightness value
The display brightness of display area is not higher than the average brightness of the multiple display area.Improving the smallest viewing area of brightness value
When the driving current in domain, the brightness value for being at most adjusted to the display area is identical as the average brightness r of multiple display areas, if
Continuation up improve, will lead to the display area display brightness variation it is excessive, cause the display area driving current and its
The driving current of his display area has biggish gap, is unfavorable for maintaining calibration result for a long time, may cause flexible display screen
It needs often to calibrate.
It is understood that when adjusting the driving current of the smallest display area of brightness value, it is adjustable extremely
The brightness value of display area is less than the average brightness of all display areas.It is adjusted to the smallest display area of brightness value
Display brightness is equal to before the average brightness of all display areas, can stop adjusting at any time.It in some embodiments, can be with
The amplitude of adjusting is preset, such as brightness value amplitude of accommodation threshold value f2 can be set, is adjusting the smallest viewing area of brightness value
When the driving current in domain, so that the brightness value knots modification of the display area is no more than brightness value amplitude of accommodation threshold value f2, brightness value
Amplitude of accommodation threshold value f2 can preset or be customized by the user.
By adjusting the brightness of brightness value maximum and the smallest display area of brightness value, so that the brightness of each display area
Value is more concentrated, and is changed discrete state, more can quickly be reduced the dispersion degree of the brightness value of each display area.It adjusts
After the completion, step S262 is executed.
