4. Visual characteristics
4.1 Test conditions
Unless otherwise specified, this specification is defined under the following conditions.
(1) Input signal : As defined in 3.3, 1680 x 1050
non-interlaced mode (1680X1050@60Hz 146.25MHz), 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
To follow Panel specification.
sRGB = 80 ± 10 nits (suppliers to input)
4.3 Image size
Actual display size 464.94 mm x 290.5875 mm
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% (Follow panel spec.)
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
