4.4 Brightness uniformity
Set contrast at 100% and turn the brightness to get average above 200 nits at centre of the screen.
Apply the Fig 1; it should comply with the following formula:
B_min
X
100%
>75%
B_max
Where B_max =Maximum brightness
B_min = Minimum brightness
4.5 Check Cross talk (S)
Apply Pattern 2. Set contrast and brightness at 100 %.
Measure YA. Then output Pattern 3 and measure YB.
the cross talk value :
ABS( YA - YB )
⎯⎯⎯⎯⎯⎯⎯⎯⎯
X 100% < 2.0 %
YA
4.6 White color adjustment
There are three factory preset white color 9300K, 6500K, sRGB.
Apply full white pattern, with brightness in 100 % position and the contrast control at 50 % position.
The 1931 CIE Chromaticity (color triangle) diagram (x,y)
coordinate for the screen center should be:
Product spec.
9300K CIE coordinates X = 0.283 ± 0.02 Y = 0.297 ± 0.02
6500K/ sRGB CIE coordinates
X = 0.313 ± 0.02 Y = 0.329 ± 0.02
sRGB CIE coordinates X = 0.313 ± 0.02 Y = 0.329 ± 0.02
Production alignment spec.
