In step 103, according to identified R, G, B component offset data, respectively to R component, G components and B component It is adjusted.
In the embodiment of the present disclosure, terminal can be smart mobile phone, panel computer, PDA (Personal Digital Assistant, personal digital assistant), E-book reader, the electronic equipment with display screen such as multimedia player.Display Screen can be LCDs, it is also possible to OLED display screen.
Because the data value of the data value of light ource electric current and R component, the data value of B component, G components can influence color Coordinate, therefore, it can it is determined that in the case of luminous ource electric current, by the data value, the data value of B component, the G that adjust R component 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 the offset data of R component, the offset data of B component and G components of element, using identified R, G, B component Offset data, R component, G components and B component are adjusted respectively, so as to realize the compensation to screen display color.
On current information, current information is intended to indicate that the information of size of current.
In one example, can be current value.The embodiment is applied to terminal can get luminous current value in a steady stream Situation.
In another example, user adjusts size of current, terminal device often through the arranges value for setting register Current value cannot be known, can but be easy to get the arranges value of register, therefore, current information can be intended to indicate that electricity Flow the arranges value of the register of size.The span of the arranges value of register can be 0-255, in other examples, value It is bigger that scope can also be set, to improve the precision of size of current adjustment.
On offset data, offset data is can be by the compensation of chromaticity coordinates actual value for color is sat when screen color deflects Mark the data of desired value.In this embodiment it is possible to the offset data according to identified R component is adjusted to R component, root G components are adjusted according to the offset data of identified G components, the offset data according to identified B component is entered to B component Row adjustment, so as to realize, by the color compensating of deviation to desired color, improving display effect.
In one example, offset data can be the data value that R, G, B component need to be compensated, and be needed to mend according to R, G, B component The data value repaid is adjusted to R component, G components and B component respectively.
In another example, offset data is adjustment ratio.In this embodiment it is possible to be previously stored with current information The adjustment ratio of adjustment ratio, B component with the R component of pixel, the corresponding relation of the adjustment ratio of G components, in corresponding relation, Chromaticity coordinates variable quantity that current information causes and adjust what is caused after R, G, B component respectively using the adjustment ratio of 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 be chromaticity coordinates change Decrement.Chromaticity coordinates increments of change is properly termed as chromaticity coordinates influence increment, is the difference of chromaticity coordinates measured value and chromaticity coordinates desired value； Chromaticity coordinates change decrement is properly termed as chromaticity coordinates influence decrement, is the difference of chromaticity coordinates desired value and chromaticity coordinates measured value, so that Realize, by the color compensating of deviation to desired color, improving display effect.
Therefore, after the current flow information for getting light emitting source, current flow information can be determined according to corresponding relation The adjustment ratio of corresponding R component, the adjustment ratio of B component, the adjustment ratio of G components, and according to the tune of identified R component Whole ratio is adjusted to R component, and the adjustment ratio according to identified G components is adjusted to G components, according to identified The adjustment ratio of B component is adjusted to B component, so as to realize the compensation to screen display color.
It can be seen that, determine adjustment ratio, the adjustment ratio of B component, the purpose of the adjustment ratio of G components of R component, be in order to Using ratio adjustment R, G, B component is adjusted, the compensation to screen display color is realized.Due to the compensation of each pixel same components Ratio it is identical, the mode of proportion of utilization is adjusted can improve regulated efficiency, and then quick realize that screen color is compensated.
In an optional implementation, because 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 of the R component of each pixel in display content, G components Data value, while data value can also be changed, and the data value after change is transmitted to the driving IC of screen, by driving IC Control screen display corresponding contents.
Based on this, it is possible to use terminal handler directly changes the data value of R, G, B component, by the side for changing data value Formula is realized compensating the color that screen display goes out.It is found by the applicant that, although 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 components can be the adjustment ratio of the data value of G components, The adjustment ratio of the B component can be the adjustment ratio of the data value of B component.Accordingly, the corresponding relation is electric current letter Adjustment ratio, the adjustment ratio of the data value of B component, the adjustment of the data value of G components of the data value of the R component of breath and pixel The corresponding relation of ratio.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, the adjustment ratio of the data value of G components are abbreviated as the adjustment ratio of R, G, the data value of B component.
After the adjustment ratio for determining R, G, the data value of B component according to corresponding relation and current flow information, can be with According to R, G, the data value of B component adjustment ratio, R, G, the data value of B component of each pixel are adjusted respectively.
It can be seen that, the present embodiment directly changes the data value of R, G, B component by processor, so as to realize to screen color Compensation.
The adjustment of the current luminous ource electric current of terminal has two ways, and one kind is to control luminous ource electric current by mainboard chip, One kind is to drive IC to control luminous ource electric current by screen.Both modes AP can get present current value, and IC is only When having ource electric current luminous by screen driving IC controls, current value can be just got.Based on this, it is optional that the disclosure provides another Implementation, the implementation is applied to the situation of the screen IC luminous ource electric currents of control, and current light emitting source curent change, AP is notified that the situation of screen IC.The driving IC of screen can be applied to the voltage on screen by adjustment, realize to R, G, B point The adjustment of the data value of amount, and then control color to show.When voltage is big, screen is bright, and transmitance is high, R, G, the data of B component Value is big.The driving IC of screen can respectively change the voltage being applied on R, G, B, by the change of maximum voltage, to corresponding R, G, the voltage of B component are multiplied by a parameter less than 1, reach the purpose of compensation color change.
Based on this, it is possible to use screen drives modification to be applied to the voltage in R, G, channel B, by the side for changing magnitude of voltage Formula is realized being adjusted R component, G components and B component.Again because the magnitude of voltage of each pixel same components adjustment may not Together, but it is full frame in each pixel same components adjustment voltage ratio be identical.Therefore, the adjustment ratio of the R component Example can be the adjustment ratio of the magnitude of voltage of R component, and the adjustment ratio of the G components can be the adjustment of the magnitude of voltage of G components Ratio, the adjustment ratio of the B component can be the adjustment ratio of the magnitude of voltage of B component.Accordingly, the corresponding relation is electricity The adjustment ratio of the magnitude of voltage of the R component of stream information and pixel, the adjustment ratio of the magnitude of voltage of B component, the magnitude of voltage of G components The corresponding relation of adjustment ratio.For convenience, can be by the adjustment ratio of the magnitude of voltage of the R component of pixel, the data value of B component Adjustment ratio, the adjustment ratio of the data value of G components be abbreviated as the adjustment ratio of R, G, the magnitude of voltage of B component.
After the adjustment ratio for determining R, G, the magnitude of voltage of B component according to corresponding relation and current flow information, can be with According to R, G, the magnitude of voltage of B component adjustment ratio, adjustment respectively is applied to voltage in R, G, channel B.For example, will be applied to Voltage on R passages is multiplied by the adjustment ratio of the magnitude of voltage of R component, using the voltage after adjustment as should be applied on R passages Voltage.
It can be seen that, the present embodiment drives modification to be applied to the voltage in R, G, channel B by screen, so as to realize to screen face The compensation of color.
As seen from the above-described embodiment, the present embodiment is adjustment ratio, the B component of the R component according to current information and pixel Adjustment ratio, the corresponding relation of the adjustment ratio of G components, determine the adjustment ratio of the corresponding R of current flow information, G, B component Example, and adjustment ratio using R, G, B component is adjusted to R component, G components and B component respectively, so as to realize screen color Quick compensation, improves display effect of the screen under different electric currents, it is to avoid with the change of luminous ource electric current, screen color occurs The defect of deviation.
The adjustment ratio of the R component on current information and pixel, the adjustment ratio of B component, the adjustment ratio of G components Corresponding relation, several generating modes introduced below.Wherein, the adjustment ratio of R component, the adjustment ratio of B component and G components Adjustment ratio, can be referred to as the adjustment ratio of R, G, B component.
In an optional implementation, decrement function is changed according to chromaticity coordinates increments of change function and chromaticity coordinates, really The adjustment ratio of the R component of the fixed current information and pixel, the adjustment ratio of B component, the correspondence pass of the adjustment ratio of G components System.
Wherein, chromaticity coordinates increments of change function changes in decrement function with chromaticity coordinates, and one of function is based on the first sample The relation of chromaticity coordinates measured value, chromaticity coordinates desired value and current information is obtained in notebook data, and 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 components in notebook data Adjustment ratio relation obtain.
Meanwhile, the first sample data are identical with chromaticity coordinates desired value in the second sample data.Chromaticity coordinates desired value is Expect chromaticity coordinates value during the optimal display effect for reaching.In the test process of generation sample data, often first by initial shape State is transferred to optimal dispaly state, for example, it is maximum to be set to maximum and will adjust ratio setting the arranges value of register. In one example, by taking the display screen with backlight as an example, if the scope of the arranges value of register is 0~255, adjustment Ratio be 0~100%, then in test process first by the arranges value of register be set to 255 and adjustment ratio setting be 100%, the chromaticity coordinates value under the conditions of this is defined as chromaticity coordinates initial value/chromaticity coordinates desired value.OLED display screen exists multiple Optimal dispaly state, can be using the chromaticity coordinates value under wherein any one optimal dispaly state as chromaticity coordinates desired value.
Further, in order to ensure to set up function in the case of unitary variant, the first sample data are in R, G, B Tested under conditions of the adjustment ratio of component is constant and obtained, second sample data is in the constant condition of current information Lower test is obtained.
In one example, the first sample data are to be the condition of maximum in the adjustment ratio of R, G, B component Lower test is obtained, and second sample data is to test to obtain under conditions of current information is maximum.
It can be seen that, first sample data are under conditions of the adjustment ratio of R, G, B component is maximum in the present embodiment Test is obtained, and the second sample data is to test to obtain under conditions of current information is maximum, such that it is able to improve acquisition the The precision of one sample data and the second sample data, and then improve the precision that chromaticity coordinates changes add drop flow function.
In the present embodiment, when chromaticity coordinates increments of change is identical with chromaticity coordinates change decrement, you can realize screen color Compensation, then enter row equivalent by chromaticity coordinates increments of change function and chromaticity coordinates change decrement function, and the function of acquisition is electric current letter Adjustment ratio, the adjustment ratio of B component, the function of the corresponding relation of the adjustment ratio of G components of the R component of breath and pixel.Tool Body, understand for convenience, by based on chromaticity coordinates measured value, chromaticity coordinates desired value and current information in first sample data The function that relation is obtained is referred to as the first chromaticity coordinates change 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 relation of the adjustment ratio of G components are obtained Referred to as the second chromaticity coordinates changes function.When the first chromaticity coordinates change function is chromaticity coordinates increments of change function, the second chromaticity coordinates Change function is that chromaticity coordinates changes decrement function, increment and decrement is of equal value, you can to obtain current information and R, G, the tune of B component The corresponding relation of whole ratio.When the first chromaticity coordinates change function is that chromaticity coordinates changes decrement function, the second chromaticity coordinates change letter Number is chromaticity coordinates increments of change function, increment and decrement is of equal value, you can to obtain current information and R, G, the adjustment ratio of B component Corresponding relation.
Below first to the relation based on chromaticity coordinates measured value, chromaticity coordinates desired value and current information in first sample data The function of acquisition is introduced.
Relation based on chromaticity coordinates measured value, chromaticity coordinates desired value and current information in first sample data can be obtained The function (curve) that electric current influences on screen color, is properly termed as the first chromaticity coordinates change function.Tested under certain current information Obtain chromaticity coordinates measured value, then can be using the current information, chromaticity coordinates measured value, chromaticity coordinates desired value as one group of test number According to.After some groups of test datas are obtained, can be according to the homochromy radial expectation of chromaticity coordinates measured value in every group of test data Difference obtains chromaticity coordinates changing value, according to chromaticity coordinates changing value and the corresponding relation of current information, sets up the change of the first chromaticity coordinates Function.
In one example, light emitting source is directly tested under different electric currents to the influence of Show Color, is obtained according to test Data set up the first chromaticity coordinates change function.
Although however, above-mentioned this test has good generality, in the assembling process of screen module, there is some its The use of his membrane material, such as cold light panel, light guide plate, sheet emitting etc., this kind of membrane material also can have certain shadow to the color for showing Ring, cause the first chromaticity coordinates change function that aforesaid way is obtained to have deviation with actual color coordinate change function, precision is inadequate.
Based on this, in another example, can be by screen module group assembling after, directly test electric current change for screen color The influence of coloured silk change, the data obtained according to test set up the first chromaticity coordinates change function.
This mode can remove the influence of various other membrane materials and technique for terminal to be measured, directly obtain Final function, can more accurately as compensation.But, if total difference is larger, it is difficult to set up most suitable Changes in coordinates function of the same colour.
Based on this, the disclosure also provides another way and sets up the first changes in coordinates function, specifically, described be based on first The function that the relation of chromaticity coordinates measured value, chromaticity coordinates desired value and current information is obtained in sample data, including：Based on each son The subfunction that the relation of chromaticity coordinates measured value, chromaticity coordinates desired value and current information is obtained in sample data, different subsamples The different subfunctions of data correspondence, the increment notebook data is to be drawn first sample data according to the span of current information Separately win.By way of dividing electric current interval, the precision of changes in coordinates function can be improved.
In this embodiment it is possible to the substantial amounts of first sample data of acquisition of sampling.Span according to current information will First sample data divide and obtain at least two increment notebook datas.In same increment notebook data, chromaticity coordinates changing value with Slope is identical in the linear relationship of current information.Because chromaticity coordinates desired value is a specific value, so same subsample In data, chromaticity coordinates measured value is identical with slope in the linear relationship of current information.
In one example, curve is drawn using first sample data, the electric current corresponding to same slope in curve is made It is an electric current interval, and the interval sample data of the electric current is referred to as increment notebook data.The different sons of the interval correspondence of different electric currents Sample data.
As shown in Fig. 2 Fig. 2 is a kind of different back facet current opponent-color coordinates of the disclosure according to an exemplary embodiment Influence curve schematic diagram.Figure it is seen that can by back facet current be divided into 1mA~5mA, 5mA~20mA, 20mA~ 25mA, 25mA~electric current intervals of 80mA tetra-, the different increment notebook datas of the interval correspondence of different electric currents, using corresponding subsample number According to the corresponding subfunction of generation, it is seen then that the subfunction corresponding to different electric currents intervals is different.
It is understood that this example is to represent current information with current value, and in actual applications, can be with register Arranges value represents current information, then the arranges value of register is divided into multiple galvanic areas.With the scope of arranges value as 0~ As a example by 255, electric current interval one can be divided into:255~208, electric current interval two:208~98, electric current interval three:98~8, electricity Stream interval four:8~0.Specific dividing mode is different according to different product difference, therefore demarcation interval and interval number are herein Do not limit,
The different subfunctions of the interval correspondence of different electric currents, for example：
When light emitting source is in electric current interval 1, subfunction is Xn=k1*BL+b1；Yn=j1*BL+c1；
When light emitting source is in electric current interval 2, subfunction is Xn=k2*BL+b2；Yn=j2*BL+c2；
When light emitting source is in electric current interval 3, subfunction is Xn=k3*BL+b3；Yn=j3*BL+c3；
When light emitting source is in electric current interval 4, subfunction is Xn=k4*BL+b4；Yn=j4*BL+c4.
Wherein, BL is variable, represents the arranges value of current register, Xn、YnRepresent the chromaticity coordinates change under this arranges value The difference of value, such as chromaticity coordinates measured value and chromaticity coordinates desired value, k1, b1, c1, k2, b2, c2, k3, b3, c3, k4, b4, c4 are represented Constant, after being trained using first sample data, you can determine these constants.
Next to the adjustment based on chromaticity coordinates measured value, chromaticity coordinates desired value, the R component of pixel in the second sample data The function that ratio, the adjustment ratio of B component, the relation of the adjustment ratio of G components are obtained is introduced, and describes for convenience, can It is referred to as the second chromaticity coordinates change function with by the class function.
Due to can directly change the data value of R, G, B component by processor, the compensation to screen color is realized；Or Drive adjustment to be applied to the voltage in R, G, channel B by screen, realize the compensation to screen color, therefore be directed to two kinds respectively The chromaticity coordinates of briefing second changes function.
The situation of data value is directly changed for processor, the chromaticity coordinates measured value under different adjustment ratios can be gathered. Tested under certain adjustment ratio and obtain chromaticity coordinates measured value, then can be by the adjustment ratio of the data value of R component, the number of G components According to adjustment ratio, the adjustment ratio of the data value of B component, chromaticity coordinates measured value, the chromaticity coordinates desired value of value as one group of test Data.After some groups of test datas are obtained, can be according to the homochromy radial expectation of chromaticity coordinates measured value in every group of test data Difference obtain chromaticity coordinates changing value, the data of adjustment ratio, G components according to chromaticity coordinates changing value and the data value of R component The corresponding relation of the adjustment ratio of value, the adjustment ratio of the data value of B component, sets up the second chromaticity coordinates change function.
In one example, the corresponding chromaticity coordinates change function of R, G, B component can respectively be set up.For example：
XnR=nR*f1+e1；YnR=nR*h1+g1；
XnG=nG*f2+e2；YnG=nG*h2+g2；
XnB=nB*f3+e3；YnG=nB*h3+g3.
Wherein, nR represents the adjustment ratio of the data value of R component, and nG represents the adjustment ratio of the data value of G components, nB tables Show the adjustment ratio of the data value of B component, f1, e1, h1, g1, f2, e2, h2, g2, f3, e3, h3, g3 represent constant respectively, After being trained using the second sample data, it may be determined that these constants.XnR、YnRRepresent the color for being changed by R component and causing change The difference that chromaticity coordinates desired value is surveyed with chromaticity coordinates under changes in coordinates value, such as R component；XnG、YnGRepresent to be changed by G components and cause The color coordinates changing value of change, XnB、YnBRepresent the color coordinates changing value for being changed by B component and causing change.
In one example, can be according to setting up XnR、XnG、XnBWith the relation of X, and set up YnR、YnG、YnBWith the relation of Y, So as to obtain the second chromaticity coordinates change function.
In another example, because red component influences larger to X values, smaller is influenceed on Y value, red component reduction, X Value diminishes；Green component influences smaller to X values, influences larger to Y value, and green component reduction, Y value diminishes；Blue component to X and Y has an impact, and blue component reduction, X and Y becomes big.
Based on this, if current reduction chromaticity coordinates X values occurs and Y value becomes big, such as the efficiency of red luminescent material is higher than it The situation of the efficiency of his color luminescent material, then can make X values be reduced to desired value by way of reducing R component, by reducing The mode of G components, makes Y value be reduced to desired value.If there are chromaticity coordinates X values in current reduction and Y value diminishes, such as blue light material Efficiency higher than other color luminescent materials efficiency situation, then can first reduce B component, by X and Y be all adjusted to one it is larger Value, X values are then adjusted to desired value with the mode for reducing R component, Y value is adjusted to desired value by the mode of reduction G components. Through the above way, the second sample data can be obtained, so as to obtain the second chromaticity coordinates change function according to the second sample data.
For screen drive control R, G, the situation of channel B voltage, the chromaticity coordinates reality under different adjustment ratios can be gathered Measured value.Tested under certain adjustment ratio and obtain chromaticity coordinates measured value, then can be by the adjustment ratio of the magnitude of voltage of R component, G components Magnitude of voltage adjustment ratio, the adjustment ratio of the magnitude of voltage of B component, chromaticity coordinates measured value, chromaticity coordinates desired value as one group Test data.After some groups of test datas are obtained, can be according to chromaticity coordinates measured value in every group of test data with the chromaticity coordinates phase The difference of prestige value obtains chromaticity coordinates changing value, the adjustment ratio, G components according to chromaticity coordinates changing value and the magnitude of voltage of R component The corresponding relation of the adjustment ratio of magnitude of voltage, the adjustment ratio of the magnitude of voltage of B component, sets up the second chromaticity coordinates change function.
Specifically set up the mode that mode directly changes mentioned by data value with above-mentioned processor similar, no longer go to live in the household of one's in-laws on getting married one by one herein State.
It is determined that after the first chromaticity coordinates change function and the second chromaticity coordinates change function, function is changed in the first chromaticity coordinates During for chromaticity coordinates increments of change function, filter out as the second chromaticity coordinates of chromaticity coordinates change decrement function changes function.By increment Corresponding expression formula is added with the expression formula corresponding to decrement, is as a result 0, you can obtain current information and R, G, B component The corresponding relation of adjustment ratio.When the first chromaticity coordinates change function is that chromaticity coordinates changes decrement function, it is chromaticity coordinates to filter out The second chromaticity coordinates change function of increments of change function, by the expression formula corresponding to increment and the expression formula phase corresponding to decrement Plus, as a result it is 0, you can obtain current information and R, G, the corresponding relation of the adjustment ratio of B component.
In an optional implementation, because the first chromaticity coordinates change function can include at least two subfunctions, The different subfunctions of the interval correspondence of different electric currents, then different electric currents are interval can correspond to different current informations with the R component of pixel Adjustment ratio, the adjustment ratio of B component, the corresponding relation of the adjustment ratio of G components.
