The film thickness of color blocking block.Specifically, 1) for Btc48 color lump, due to Wx and Wy be all it is bigger than normal, blue color blocking can be reduced
The film thickness of block increases the film thickness of green color blocking block to reduce Wx to reduce Wy, at the same need to reduce the film thickness of red color resistance block with
White point coordinates are balanced, to realize the white point coordinates of object display device and reference display device in target white point coordinate range
It is interior；2) for Btc70 color lump, due to Wx and Wy be all it is less than normal, the film thickness of blue color blocking block can be increased to increase Wx,
Reduce the film thickness of green color blocking block to increase Wy, while needing to increase the film thickness of red color resistance block to balance white point coordinates, thus
Realization object display device and the white point coordinates of reference display device are in target white point coordinate range.On this basis, right
The adjustment of the film thickness of color blocking block and the optical parameter of display device sequence can be found in table 3.

It closes.
Illustratively, it can refer to Figure 16, P represents color 1, and Q represents color 2, and M represents the secondary colour of P+Q, C1 and C2 difference
For the sum of color 1 and the tristimulus values of color 2, i.e. C1=X1+Y1+Z1, C2=X2+Y2+Z2, then according to center of gravity law:
Indicate that the distance of QM is inversely proportional with C2, i.e., ratio shared by C2 is bigger in secondary colour, and the distance of QM is shorter.
Similarly, since white point is as made of tri- mixture of colours of R, G and B, therefore its white color coordinates being mixed into is also with three
The ratio of the tristimulus values sum of kind color is directly related, can adjust white point coordinates by adjusting tristimulus values ratio.Such as provide
R, brightness value RY, GY and BY of tri- color of G and B, so that it may calculate the respective tristimulus values of three colors:

Wy and white brightness value WY can be obtained by the superposition calculation of the tristimulus values of tri- color of RGB.Therefore fixed according to center of gravity
Rule, the positions of white point coordinates can generally through adjustment RGB brightness RY GY BY weight be adjusted, and the brightness of RGB
It is to be inversely proportional with the film thickness of color blocking, it can the position of white point coordinates is adjusted by adjusting film thickness.
For example, the variation of green color blocking block film thickness directly affect be green light brightness variation, i.e. GY value (representing brightness).
