And computer program is described in detail.
Fig. 1 is a kind of flow diagram of the correction optimization method of display screen provided by the embodiment of the present application.
As shown in Figure 1, the correction optimization method of the display screen, comprising the following steps:
Step 101, control display screen enters reference mode.
Wherein, reference mode refers to the conventional display pattern of display screen.It is conventional aobvious in the actual use of electronic equipment
Show that mode is the most common brightness of display screen display pattern of user, therefore, in a kind of possible way of realization of the embodiment of the present application
In, it can be using the conventional display pattern of display screen as reference mode.
It should be noted that electricity where display screen can be passed through in a kind of possible way of realization of the embodiment of the present application
Setting menu in sub- equipment, modifies the brightness display pattern of display screen, enters reference mode to control display screen.
In the embodiment of the present application, display screen can be AMOLED display screen.AMOLED is as a kind of emerging display skill
Art obtains the attention of more and more electronic equipment manufacturers.Compared with traditional liquid crystal display, AMOLED display screen has
Self luminous characteristic can be made into soft, transparent, arbitrary shape display, and have broader visual angle, higher refresh rate
Thinner size and image quality be clear, energy-efficient advantage, is next-generation most potential novel planar display technology.Therefore,
More and more used in the mobile devices such as smart phone, tablet computer.
Step 102, the display screen is corrected under the reference mode to generate N Reference Alignment value.
Wherein, it corrects, refers to gamma correction, i.e., the gamma parameter of display screen is corrected, so that display screen is bright
Degree variation meets human eye to the law of perception of brightness, promotes the display effect of display screen.
Correspondingly, reference calibration value, which refers to, carries out display screen when carrying out gamma correction to display screen under reference mode
After correction, so that the display effect of display screen meets the display screen gamma parameter of human eye characteristic.
It should be noted that the parameter of display screen includes resolution ratio, brightness, contrast, gamma etc., these parameters are determined
The quality of display displayed content, wherein brightness, contrast, colour gamut, gamma are even more important.
Brightness is the light levels of display screen, and unit is the every square meter (cd/m of candela2), i.e. the luminous intensity of unit area.
The brightness of display screen is arranged, related with luminous intensity in use environment.For example, the indoor television set used, brightness of display screen setting
In 70-300cd/m2Between；Smart phone now can automatically adjust brightness of display screen according to environment light, and mobile phone display screen is bright
Degree setting range is wider, about 40-800cd/m2。
Contrast refers to the ratio of display screen maximum brightness and minimum brightness.Under reasonable brightness value, contrast is higher,
The gradation that it can show is abundanter, and the general method for reducing black picture brightness improves contrast.
Display screen colour gamut is the characterization of the bright-coloured degree of display color.Display screen colour gamut is with display screen three primary colors in the world
The illumination committee (English: International Commission on illumination, French: Commission
Internationale de l ' Eclairage, French are referred to as CIE) triangle area that surrounds on chromatic diagram is molecule, with
National Television System Committee (National Television Standards Committee, abbreviation NTSC) is advised
The triangle area that fixed three primary colors surround in CIE chromaticity diagram is denominator, and the percentage acquired is as shown in Fig. 2 (b)
The colour gamut schematic diagram of display screen.
It is the schematic diagram of CIE1931 color space as shown in Fig. 2 (a), the visible color of the mankind is empty in CIE1931 color
Between in constitute a shape of a hoof, three color of RGB (RGB) is respectively at three endpoint locations in the shape of a hoof.In CIE1931
In, color is indicated by the chromaticity coordinates of horizontal direction x, vertical direction y, for example, the chromaticity coordinates of reference white be (x0.31,
Y0.33), the chromaticity coordinates of three color of red, green, blue respectively (x0.67, y0.33), (x0.21, y0.71), (x0.14, y0.08),
NTSC color gamut is the triangle color area of this trichromatic coordinates point line composition.
Display screen colour gamut is the most important parameters for evaluating display screen display effect, is display screen color summation in NTSC
Accounting rate in colour gamut.Display screen colour gamut is bigger, and the color that display screen can be shown is abundanter；Display screen colour gamut is smaller, display
It is deficienter to shield the color that can be shown.Liquid crystal display colour gamut, is limited by the backlight colour gamut of liquid crystal display, and AMOLED is shown
Shield colour gamut, depends on luminescent material.Either liquid crystal display or AMOLED display screen, display screen body complete, display
Screen colour gamut uniquely determines.
Display screen colour gamut is that display screen shows that color abundant is laid a good foundation, the color table of display screen at different brightnesses
Now determined by the gamma of display screen.Display screen needs the gamma of appropriate mix, and display screen could be allowed to show different brightness, difference
In the state of picture, optimal display effect is presented.Therefore, in the embodiment of the present application, the gamma parameter to display screen is needed
It is corrected, to guarantee display effect of the display screen in various brightness display patterns.
It should be noted that human eye forms a kind of characteristic during human evolution: in low-light level environment, to bright
Degree variation is sensitive, can perceive the luminance difference of very little；It is insensitive to brightness change in high-brightness environment, brightness value variation
When larger, human eye could be differentiated.This characteristic is called the gamma characteristic of human eye.For corresponding display screen, brightness and input are exported
Gamma electric voltage is substantially linear.From most bright white picture to most dark black picture, brightness uniformity is divided into n equal part, with regard to shape
At n grades of grey menus.Due to the characteristic of above-mentioned human eye, the grayscale of this uniform n equal part is appeared to be as shown in Fig. 2 (c) in human eye
Image, smaller in the part discrimination of high brightness, low-light level part is on the contrary.
It is understood that due to the characteristic that human eye perceives luminance non-linearity, if to obtain the brightness of even variation
Impression, then the brightness that display screen is shown just needs non-uniform change, to adapt to the gamma characteristic of human eye, this brightness and grayscale
The non-linear relation parameter of degree is gamma parameter, is referred to as gamma curve according to the curve that this parameter is depicted.Gamma
The parameter declaration non-linear relation of brightness and grayscale, the i.e. non-linear relation of brightness and gamma electric voltage, can be bright by display screen
Degree is reduced to following formula with gamma input voltage:
Output=k × InputGamma
Wherein, k is constant, be for each display screen it is fixed, Input be input panel gamma electricity
Pressure, Output is the output brightness of display screen, and Gamma is the gamma parameter of display screen.By the display of Gamma parameter correction
Device can accurately show the brightness of different brackets grayscale.
It should be noted that display screen can be made correctly to show the gamma parameter of greyscale level picture, referred to as display screen
Optimal gamma parameter.In the embodiment of the present application, N Reference Alignment value refers to the progress gamma school under display screen reference mode
Just, the optimal gamma parameter of acquisition.
In the embodiment of the present application, when carrying out gamma correction to display screen, need to follow measurement principle, i.e., in display screen
In the case that maximum brightness value is certain, maximum brightness range is divided into n grayscale, and guarantees the color in different grey menus
Coordinate holding is stablized constant or stable in preset error range.For example, to display in the conventional display pattern of display screen
Screen is when being corrected, it is first determined goes out in conventional display pattern, the maximum brightness value of display screen, and by the 0 value maximum brightness value
Between brightness range be divided into n grayscale, and preset the corresponding brightness value of each grayscale and chromaticity coordinates, display screen inputted later
The corresponding gamma electric voltage of different gamma values debugs display screen, and then the brightness of n grayscale will be made in preset gamma
Curve, while gamma value of the chromaticity coordinates of each grayscale in default range, are determined as N Reference Alignment value.
For example, the corresponding maximum brightness value of conventional display pattern of display screen is 500cd/m2, then can be by 0-
500cd/m2Brightness range be divided into 255 grayscale, and the default corresponding brightness value of 255 grayscale and various colors exist
0-500cd/m2Chromaticity coordinates range in brightness range, for example, by white chromaticity coordinates range be preset as x 0.28 to 0.32 it
Between, y is between 0.29 to 0.33.It inputs different gamma electric voltages later to be corrected display screen, when some gamma value is corresponding
Gamma electric voltage so that the brightness gamma curve of 255 grayscale gamma curve corresponding with the gamma value is identical, while various face
Color is in the chromaticity coordinates that each grayscale is shown in default range, i.e., picture color is shown normally, then can determine the gamma value
For benchmark corrected value.
It should be noted that the example above is exemplary only, the limitation to the application cannot be considered as.To display screen into
The error range of row timing, chromaticity coordinates should be determined as lesser value, so that the N Reference Alignment value obtained is more accurate.Actually make
Used time, the error range of chromaticity coordinates can be preset according to actual needs, the embodiment of the present application does not limit this.
Step 103, the corresponding offset correction values of the display screen reference model are obtained.
Wherein, display screen reference model, refers to other brightness display patterns of display screen, reference model can have it is multiple,
It is such as always on mode (AOD), hi-bright mode (HBM), in being always in mode for display screen, maximum brightness value is generally in 40-
50cd/m2Between, in the hi-bright mode of display screen, maximum brightness value can achieve 800cd/m2。
Wherein, the corresponding offset correction values of reference model refer to the inclined of corrected value in reference model and N Reference Alignment value
Shifting amount.When carrying out gamma correction to display screen, offset correction values refer to the corresponding optimal gamma parameter of reference model and benchmark
The offset of the corresponding optimal gamma parameter of mode.
It should be noted that the brightness of display screen display pattern that the electronic equipment where display screen receives user's input is repaired
When changing instruction, the corresponding offset correction values of user's reference model to be adjusted to can be obtained automatically, carry out the automatic of display screen
Correction, and then the corresponding corrected value of display screen is changed to the corresponding corrected value of reference model, to guarantee display screen different bright
Spend the display effect under display pattern.
In the embodiment of the present application, the corresponding offset correction values of display screen reference model can be counts through a large number of experiments
According to acquisition, and be preset in the electronic equipment where display screen, with when the reference model to display screen is corrected, directly from
