HUDSON 9
79
signal sources must have 75 ohm output impedance.
(2) Luminance setting : controls to be set to 300 nits (typical ) with
full screen 100 % duty cycle white signal
(3) Warm up: more than 30 minutes after power on with signal supplied.
(4) Ambient light: 400 -- 600 lux.
(5) Ambient temperature: 20 ± 5 °C
4.2 Brightness
Just follow panel specification.
4.3 Image size
Actual display size: 376.32(H)*301.056(V)
4.4 Brightness uniformity
Set contrast at 100% and turn the brightness at 100%
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, 6500 and sRGB Align by FGA function.
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:
