4.4 Brightness uniformity
Set contrast at 100% and turn the brightness to get average above 300 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% < 1.5 %
YA
4.6 White color adjustment
There are three factory preset white color 9300K, 6500K, sRGB.
Apply full gray64 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:
9300K CIE coordinates X = 0.283 ±0.020 Y = 0.297 ±0.020
6500K/ sRGB CIE coordinates X = 0.313 ±0.020 Y = 0.329 ±0.020
sRGB CIE coordinates X = 0.313 ±0.020 Y = 0.329 ±0.020
