Currently, with light emitting source curent change in screen, due to that can have the pace of change of different colours luminescent material difference, The color that then screen is shown can deviate.For OLED display screen, light emitting source OLED, for liquid crystal display Speech, light emitting source is backlight, such as LED backlight.
For the display screen with backlight, with the variation of back facet current, the color of backlight (backlight) can occur Deviation.The phenomenon that backlight of especially wide colour gamut, color deviates, can be obvious.The red light material that wide colour gamut uses exists Pace of change under low current is higher than the pace of change of other colors, so when guaranteeing high current white effect, under low current White picture will be partially red.For example, backlight LED light can will appear partially red show with the reduction of brightness and electric current, the color of lamp As.Back facet current is generally within the scope of 0-20mA, and with the reduction of electric current, chromaticity coordinates X value increases, and illustrates that color is partially red, Y value Can be bigger than normal, only the amplification of Y is smaller, so whole partially red phenomenon occur.
For OLED display screen, when OLED current is higher than some current threshold, the pace of change of different colours luminescent material It will not differ greatly, single screen calibration can be carried out.When OLED current is lower than some current threshold, the change of different colours luminescent material Changing speed can differ greatly, thus the phenomenon that will appear colour cast.
In order to avoid the defect deviated with the variation of luminous ource electric current, screen display color, the disclosure provides one Kind color compensation method is realized with compensating chromaticity coordinates variation of the terminal screen due to light emitting source under different electric currents in different hairs Best display effect can be reached under source current.
As shown in Figure 1, Fig. 1 is a kind of disclosure process of color compensation method shown according to an exemplary embodiment Figure, this method can be used in terminal, comprising the following steps:
In a step 101, the current flow information of light emitting source in screen is obtained.

In step 103, according to the offset data of identified R, G, B component, respectively to R component, G component and B component It is adjusted.
In the embodiment of the present disclosure, terminal can be smart phone, tablet computer, PDA (Personal Digital Assistant, personal digital assistant), the electronic equipment of E-book reader, multimedia player etc. with display screen.Display Screen can be liquid crystal display, can also be with OLED display screen.
Since the data value of shine ource electric current and the data value of R component, the data value of B component, G component will affect color Coordinate therefore can be in the case where determining luminous ource electric current, by adjusting the data value of R component, the data value of B component, G The data value of component realizes the compensation to screen display color.The present embodiment is by determining picture corresponding with current flow information The offset data of R component, the offset data of the offset data of B component and G component of element, utilize identified R, G, B component Offset data, R component, G component and B component are adjusted respectively, to realize compensation to screen display color.
About current information, current information is intended to indicate that the information of size of current.
In one example, it can be current value.The embodiment, which is suitable for terminal, can get the current value to shine in a steady stream The case where.
In another example, user adjusts size of current, terminal device often through the setting value of setting register It can not know current value, can but be easy to get the setting value of register, therefore, current information can be intended to indicate that electricity Flow the setting value of the register of size.The value range of the setting value of register can be 0-255, in other examples, value Range can also be arranged bigger, to improve the precision of size of current adjustment.
About offset data, offset data can be compensated chromaticity coordinates actual value when screen color deflects as color seat Mark the data of desired value.In this embodiment it is possible to be adjusted according to the offset data of identified R component to R component, root G component is adjusted according to the offset data of identified G component, according to the offset data of identified B component to B component into Row adjustment improves display effect to realize the color compensating of deviation to desired color.
In one example, offset data can be the data value that R, G, B component need to compensate, and need to mend according to R, G, B component The data value repaid respectively is adjusted R component, G component and B component.
In another example, offset data is adjustment ratio.In this embodiment it is possible to be previously stored with current information With the corresponding relationship of the adjustment ratio of the R component of pixel, the adjustment ratio of B component, the adjustment ratio of G component, in corresponding relationship, Chromaticity coordinates variable quantity caused by current information, caused by being adjusted separately after R, G, B component with the adjustment ratio using R, G, B component Chromaticity coordinates variable quantity is identical, and in two chromaticity coordinates variable quantities one be chromaticity coordinates increments of change, another for chromaticity coordinates change Decrement.Chromaticity coordinates increments of change, which is properly termed as chromaticity coordinates, influences increment, is the difference of chromaticity coordinates measured value Yu chromaticity coordinates desired value； Chromaticity coordinates variation decrement, which is properly termed as chromaticity coordinates, influences decrement, is the difference of chromaticity coordinates desired value Yu chromaticity coordinates measured value, thus It realizes the color compensating of deviation to desired color, improves display effect.
Therefore, after getting the current flow information of light emitting source, current flow information can be determined according to corresponding relationship Adjustment ratio, the adjustment ratio of B component, the adjustment ratio of G component of corresponding R component, and according to the tune of identified R component Whole ratio is adjusted R component, is adjusted according to the adjustment ratio of identified G component to G component, according to identified The adjustment ratio of B component is adjusted B component, to realize the compensation to screen display color.
As it can be seen that determine R component adjustment ratio, the adjustment ratio of B component, the purpose of the adjustment ratio of G component, be in order to R, G, B component are adjusted using adjustment ratio, realizes the compensation to screen display color.Since each pixel same components compensate Ratio it is identical, the mode of proportion of utilization, which is adjusted, can be improved regulated efficiency, so fast implement screen color compensation.
In an optional implementation, since terminal AP (Application Processor, processor) can be obtained Content to be displayed is obtained, and determines the data value and B component of the data value, G component of the R component of each pixel in display content Data value, while data value can also be changed, and the data value after change is transmitted to the driving IC of screen, pass through driving IC It controls screen and shows corresponding contents.
Based on this, the data value that terminal handler directly modifies R, G, B component can use, by the side for modifying data value Formula realization compensates the color that screen is shown.Although it has been found that the data of each pixel same components compensation Value may be different, but the ratio of each pixel same components compensation is identical.Therefore, the adjustment ratio of the R component can Think the adjustment ratio of the data value of R component, the adjustment ratio of the G component can be the adjustment ratio of the data value of G component, The adjustment ratio of the B component can be the adjustment ratio of the data value of B component.Correspondingly, the corresponding relationship is electric current letter Breath and the adjustment ratio of the data value of the R component of pixel, the adjustment ratio of the data value of B component, G component data value adjustment The corresponding relationship of ratio.It for convenience, can be by the adjustment ratio of the data value of the R component of pixel, the tune of the data value of B component Whole ratio, G component data value adjustment ratio be abbreviated as R, G, B component data value adjustment ratio.
It, can be with after determining the adjustment ratio of data value of R, G, B component according to corresponding relationship and current flow information According to the adjustment ratio of R, G, the data value of B component, R, G of each pixel, the data value of B component are adjusted separately.
As it can be seen that the present embodiment directly modifies the data value of R, G, B component by processor, to realize to screen color Compensation.
At present terminal shine ource electric current adjustment there are two types of mode, one is by the luminous ource electric current of mainboard chip control, One is drive IC to control the ource electric current that shines by screen.Both modes AP can get present current value, and IC is only When having ource electric current luminous by screen driving IC control, current value can be just got.Based on this, it is optional that the disclosure provides another Implementation, which is suitable for screen IC and controls the case where shining ource electric current, and current light emitting source curent change, AP is notified that the case where screen IC.The driving IC of screen can realize by adjusting the voltage applied on the screen to R, G, B points The adjustment of the data value of amount, and then control color and show.When voltage is big, screen is bright, and transmitance is high, the data of R, G, B component Value is big.The driving IC of screen can change the voltage being applied on R, G, B respectively, by the variation of maximum voltage, to corresponding R, the voltage of G, B component achievees the purpose that compensate color change multiplied by a parameter less than 1.
Based on this, it can use screen driving modification and be applied to R, G, the voltage in channel B, pass through the side of modification voltage value Formula realization is adjusted R component, G component and B component.Again since the voltage value of each pixel same components adjustment may not Together, but it is full frame in the voltage ratio of each pixel same components adjustment be identical.Therefore, the adjustment ratio of the R component Example can be the adjustment ratio of the voltage value of R component, and the adjustment ratio of the G component can be the adjustment of the voltage value of G component The adjustment ratio of ratio, the B component can be the adjustment ratio of the voltage value of B component.Correspondingly, the corresponding relationship is electricity The adjustment ratio of the voltage value of the R component of stream information and pixel, the adjustment ratio of the voltage value of B component, G component voltage value The corresponding relationship of adjustment ratio.It for convenience, can be by the adjustment ratio of the voltage value of the R component of pixel, the data value of B component Adjustment ratio, G component data value adjustment ratio be abbreviated as R, G, B component voltage value adjustment ratio.
It, can be with after determining the adjustment ratio of voltage value of R, G, B component according to corresponding relationship and current flow information According to the adjustment ratio of R, G, the voltage value of B component, adjusts separately and be applied to R, G, the voltage in channel B.For example, will be applied to Voltage on the channel R multiplied by the voltage value of R component adjustment ratio, using voltage adjusted as should be applied on the channel R Voltage.
As it can be seen that the present embodiment is applied to R, G, the voltage in channel B by screen driving modification, to realize to screen face The compensation of color.
As seen from the above-described embodiment, the present embodiment is the adjustment ratio of the R component according to current information and pixel, B component Adjustment ratio, the adjustment ratio of G component corresponding relationship, determine the adjustment ratio of the corresponding R, G of current flow information, B component Example, and R component, G component and B component are adjusted respectively using the adjustment ratio of R, G, B component, to realize screen color Quickly compensation improves display effect of the screen under different electric currents, avoids the variation with luminous ource electric current, and screen color occurs The defect of deviation.
About the adjustment ratio of current information and the R component of pixel, the adjustment ratio of B component, the adjustment ratio of G component Corresponding relationship, several generating modes introduced below.Wherein, the adjustment ratio of R component, the adjustment ratio of B component and G component Adjustment ratio can be referred to as the adjustment ratio of R, G, B component.
In an optional implementation, according to chromaticity coordinates increments of change function and chromaticity coordinates variation decrement function, really Adjustment ratio, the adjustment ratio of B component, the corresponding of the adjustment ratio of G component of the R component of the fixed current information and pixel are closed System.
Wherein, in chromaticity coordinates increments of change function and chromaticity coordinates variation decrement function, one of function is based on the first sample The relationship of chromaticity coordinates measured value, chromaticity coordinates desired value and current information obtains in notebook data, another function is based on the second sample Chromaticity coordinates measured value, chromaticity coordinates desired value, the adjustment ratio of the R component of pixel, the adjustment ratio of B component, G component in notebook data Adjustment ratio relationship obtain.
Meanwhile the first sample data are identical as chromaticity coordinates desired value in the second sample data.Chromaticity coordinates desired value is It is expected that reach optimal display effect when chromaticity coordinates value.In the test process for generating sample data, often first by initial shape State is transferred to optimal display state, for example, setting maximum for the setting value of register and will adjust ratio setting as maximum. In one example, by taking the display screen with backlight as an example, if the range of the setting value of register is 0~255, adjustment Ratio be 0~100%, then in test process first by the setting value of register be set as 255 and adjustment ratio setting be 100%, chromaticity coordinates value under this condition is determined as chromaticity coordinates initial value/chromaticity coordinates desired value.There are multiple for OLED display screen Optimal display state, can be using the chromaticity coordinates value under wherein any one optimal display state as chromaticity coordinates desired value.
Further, in order to guarantee to establish function in the case where unitary variant, the first sample data are in R, G, B It tests and obtains under conditions of the adjustment ratio of component is constant, second sample data is the condition constant in current information Lower test obtains.
In one example, the first sample data be R, G, B component adjustment ratio be maximum value condition Lower test obtains, and second sample data is that test obtains under conditions of current information is maximum value.
As it can be seen that first sample data are under conditions of the adjustment ratio of R, G, B component is maximum value in the present embodiment Test obtains, and the second sample data is that test obtains under conditions of current information is maximum value, so as to improve acquisition the The precision of one sample data and the second sample data, and then improve the precision of chromaticity coordinates variation add drop flow function.
In the present embodiment, when chromaticity coordinates increments of change is identical as chromaticity coordinates variation decrement, screen color can be realized Compensation, then chromaticity coordinates increments of change function and chromaticity coordinates variation decrement function progress is of equal value, the function of acquisition is electric current letter The function of breath and the adjustment ratio of the R component of pixel, the corresponding relationship of the adjustment ratio of B component, the adjustment ratio of G component.Tool Body, understand for convenience, it will be based on chromaticity coordinates measured value in first sample data, chromaticity coordinates desired value and current information The function that relationship obtains is known as the first chromaticity coordinates variation function, will be based on chromaticity coordinates measured value, chromaticity coordinates in the second sample data The function that desired value, the adjustment ratio of the R component of pixel, the adjustment ratio of B component, the relationship of the adjustment ratio of G component obtain Referred to as the second chromaticity coordinates changes function.When the first chromaticity coordinates variation function is chromaticity coordinates increments of change function, the second chromaticity coordinates Changing function is chromaticity coordinates variation decrement function, and increment and decrement is of equal value, can be obtained the tune of current information and R, G, B component The corresponding relationship of whole ratio.When the first chromaticity coordinates variation function is chromaticity coordinates variation decrement function, the second chromaticity coordinates changes letter Number is chromaticity coordinates increments of change function, and increment and decrement is of equal value, can be obtained the adjustment ratio of current information and R, G, B component Corresponding relationship.
Below first to the relationship based on chromaticity coordinates measured value, chromaticity coordinates desired value and current information in first sample data The function of acquisition is introduced.
Relationship based on chromaticity coordinates measured value, chromaticity coordinates desired value and current information in first sample data can obtain The function (curve) that electric current influences screen color is properly termed as the first chromaticity coordinates variation function.It is tested under certain current information Obtain chromaticity coordinates measured value, then it can be using the current information, chromaticity coordinates measured value, chromaticity coordinates desired value as one group of test number According to.It, can be according to the homochromy radial expectation of chromaticity coordinates measured value in every group of test data after obtaining several groups test data Difference obtains chromaticity coordinates changing value, according to the corresponding relationship of chromaticity coordinates changing value and current information, establishes the variation of the first chromaticity coordinates Function.
In one example, light emitting source is directly tested under different electric currents to the influence of display color, is obtained according to test Data establish the first chromaticity coordinates variation function.
However, although above-mentioned this test has a good generality, in the assembling process of screen mould group, have it is some its Use of his membrane material, such as cold light panel, light guide plate, sheet emitting etc., this kind of membrane material can also have certain shadow to the color shown It rings, the first chromaticity coordinates variation function and actual color coordinate variation function for causing aforesaid way to obtain have deviation, and precision is inadequate.

In one example, curve is drawn using first sample data, electric current corresponding to same slope in curve is made For an electric current section, and the sample data in the electric current section is known as increment notebook data.Different electric current sections correspond to different sons Sample data.
As shown in Fig. 2, Fig. 2 is a kind of disclosure different back facet current opponent-color coordinates shown according to an exemplary embodiment Influence curve schematic diagram.Figure it is seen that back facet current can be divided into 1mA~5mA, 5mA~20mA, 20mA~ 25mA, 25mA~electric current section 80mA tetra-, different electric current sections correspond to different increment notebook datas, utilize corresponding subsample number According to the corresponding subfunction of generation, it is seen then that subfunction corresponding to different electric current sections is different.
It is understood that this example is that current information is indicated with current value, it in practical applications, can be with register Setting value indicates current information, then the setting value of register is divided into multiple galvanic areas.With the range of setting value be 0~ For 255, electric current section one: 255~208, electric current section two: 208~98, electric current section three: 98~8, electricity can be divided into Flow section four: 8~0.Specific division mode is different and different according to different product, therefore demarcation interval and section number are herein Without limitation,
Different electric current sections correspond to different subfunctions, such as:
When light emitting source is at electric current section 1, subfunction Xn=k1*BL+b1；Yn=j1*BL+c1；
When light emitting source is at electric current section 2, subfunction Xn=k2*BL+b2；Yn=j2*BL+c2；
When light emitting source is at electric current section 3, subfunction Xn=k3*BL+b3；Yn=j3*BL+c3；
When light emitting source is at electric current section 4, subfunction Xn=k4*BL+b4；Yn=j4*BL+c4.
Wherein, BL is variable, indicates the setting value of current register, Xn、YnIndicate the chromaticity coordinates variation under this setting value Value, such as the difference of chromaticity coordinates measured value and chromaticity coordinates desired value, k1, b1, c1, k2, b2, c2, k3, b3, c3, k4, b4, c4 are indicated Constant can determine these constants after being trained using first sample data.

In one example, the corresponding chromaticity coordinates variation function of R, G, B component can be established respectively.Such as:
XnR=nR*f1+e1；YnR=nR*h1+g1；
XnG=nG*f2+e2；YnG=nG*h2+g2；
XnB=nB*f3+e3；YnG=nB*h3+g3.

It in one example, can be according to establishing XnR、XnG、XnBWith the relationship of X, and establish YnR、YnG、YnBWith the relationship of Y, Change function to obtain the second chromaticity coordinates.
In another example, it is affected due to red component to X value, smaller, red component reduction, X is influenced on Y value Value becomes smaller；Green component is smaller on the influence of X value, is affected to Y value, and green component reduces, and Y value becomes smaller；Blue component to X and Y has an impact, and blue component reduces, and X and Y become larger.
Based on this, if current reduction chromaticity coordinates X value occurs and Y value becomes larger, such as the efficiency of red luminescent material is higher than it The case where efficiency of his color luminescent material, then can make X value be reduced to desired value, pass through reduction by way of reducing R component The mode of G component, makes Y value be reduced to desired value.If there is chromaticity coordinates X value in current reduction and Y value becomes smaller, such as blue light material Efficiency be higher than other color luminescent materials efficiency the case where, then can first reduce B component, by X and Y be all adjusted to one it is larger Value, X value is then adjusted to desired value with the mode for reducing R component, Y value is adjusted to desired value by the mode for reducing G component. By the above-mentioned means, the second sample data can be obtained, so that obtaining the second chromaticity coordinates according to the second sample data changes function.
The case where for screen drive control R, G, channel B voltage, the chromaticity coordinates that can be acquired under different adjustment ratios are real Measured value.Test obtains chromaticity coordinates measured value under certain adjustment ratio, then can be by the adjustment ratio of the voltage value of R component, G component The adjustment ratio of voltage value, the adjustment ratio of voltage value of B component, chromaticity coordinates measured value, chromaticity coordinates desired value is as one group Test data.It, can be according to chromaticity coordinates measured value in every group of test data with the chromaticity coordinates phase after obtaining several groups test data The difference of prestige value obtains chromaticity coordinates changing value, according to the adjustment ratio of chromaticity coordinates changing value and the voltage value of R component, G component The corresponding relationship of the adjustment ratio of voltage value, the adjustment ratio of the voltage value of B component establishes the second chromaticity coordinates variation function.
Specifically establishing mode, directly to modify mode mentioned by data value with above-mentioned processor similar, no longer goes to live in the household of one's in-laws on getting married one by one herein It states.
After determining the first chromaticity coordinates variation function and the second chromaticity coordinates variation function, change function in the first chromaticity coordinates When for chromaticity coordinates increments of change function, filters out the second chromaticity coordinates for changing decrement function for chromaticity coordinates and change function.By increment The corresponding expression formula expression formula corresponding with decrement is added, result 0, can be obtained current information and R, G, B component The corresponding relationship of adjustment ratio.When the first chromaticity coordinates variation function is chromaticity coordinates variation decrement function, filter out as chromaticity coordinates Second chromaticity coordinates of increments of change function changes function, by the expression formula phase corresponding with decrement of expression formula corresponding to increment Add, result 0, can be obtained the corresponding relationship of the adjustment ratio of current information and R, G, B component.
