It is worth identical.
Any standard in above-mentioned 6 grayscale set of coordinates initially can be being obtained using the moment by brightness and color acquisition device
Grayscale coordinate (R, G, B) is in the brightness and color data (L, x, y) for initially using the moment.Wherein, R indicates that red grayscale value, G indicate
Green grayscale value, B indicate that blue grayscale value, L indicate brightness, and x and y indicate chromaticity coordinates.For known standard gray scale coordinate (R, G,
B), brightness and color data (L, x, y) are the given data that acquisition obtains, and in (L, x, y), total measurement after color, x and y are mixed in L expression
Indicate chromaticity coordinate total after color is mixed in chromaticity coordinates expression.
When brightness indicates monochromatic brightness, such as initial use in second brightness and color data of the third standard coordinate of acquisition
It carves, brightness is monochrome blue grayscale value in the second brightness and color data of the third standard coordinate (0,0,64) of acquisition when being 64
The original intensity of Blue OLED, set at this time blue luminences as Lb '.First brightness and color data of the second standard coordinate of acquisition
Middle brightness indicates colour mixture brightness, such as initially uses moment, the first brightness color of the second standard coordinate (255,255,64) of acquisition
Degree brightness in indicates three kinds of color OLED of RGB when red and green grayscale value be 255, blue grayscale value is 64
The sum of original intensity, blue luminences are Lb at this time.Due to there are problems that mixing color pressure drop, Lb < Lb '.Second standard coordinate
(255,255,64) it is Lb/Lb ' that blue grayscale value 64, which accordingly mixes color pressure drop information,.Wherein, third standard coordinate (0,0,64)
It is corresponding with the second standard coordinate (255,255,64).Similarly, 255 phase of red grayscale value of the second standard coordinate (255,255,64)
It is Lr/Lr ' that color pressure drop information, which should be mixed, wherein Lr ' is acquired by (255,0,0)；And second standard coordinate (255,255,
64) it is Lg/Lg ' that green grayscale value 255, which accordingly mixes color pressure drop information, wherein Lg ' is acquired by (0,255,0).
Known any second standard gray scale coordinate initial uses the moment according to following colorimetry formula (1) is available
When the second standard gray scale coordinate in red OLED brightness, the green brightness of OLED and the brightness of Blue OLED.
Set colorimetry formula (1) in three matrixes successively are as follows:
The left side matrix A 1 of colorimetry formula (1) is that the color of the red grayscale value about standard gray scale coordinate (R, G, B) is sat
Mark Rx and Ry, the chromaticity coordinates Gx and Gy of green grayscale value, blue grayscale value chromaticity coordinates Bx and By constant matrices, be known
Amount.Wherein, Rx, Gx and Bx are the x-component of the corresponding color chromaticity coordinates under sRGB standard；And Ry, Gy and By are sRGB
The y-component of substandard corresponding color chromaticity coordinates.
In the intermediary matrix A2 of colorimetry formula (1), LR255It is the brightness of red 255 grayscale under sRGB standard, LG255It is
The brightness of green 255 grayscale, LB under sRGB standard255It is the brightness of blue 255 grayscale under sRGB standard.
The right matrix A 3 of colorimetry formula (1) is tristimulus values, can use the initial brightness and color data for using the moment
(L, x, y) is indicated.The coloration x and y of same standard gray scale coordinate (R, G, B) be not with using time change.
The second standard coordinate (255,255,64) can be found out first according to matrix operation shown in colorimetry formula (1)
Begin to be Lb using the blue luminences at moment, corresponding mixes color pressure drop information to calculate its.Similarly, any second standard can be calculated
Coordinate is corresponding to mix color pressure drop information, mixes color pressure drop data table to be formed.
In the embodiment of the present application, with 36 the second standard gray scale coordinates and its it is corresponding mix color pressure drop information formation mix color
Pressure drop data table.According to mix in color pressure drop data table 36 the second standard gray scale coordinates and its it is corresponding mix color pressure drop information, lead to
Any other grayscale coordinate crossed outside available this 36 the second standard gray scale coordinates of the second interpolation arithmetic mixes color pressure drop letter
Breath.As it can be seen that the available any grayscale coordinate of color pressure drop data table is corresponding to mix color pressure drop information according to mixing, that is to say, according to
