6.2.1 Room Ambient Contrast
Minimum Contrast of the display under room ambient lighting conditions of 1076
LUX [100 fC] direct incident illumination, is > 90:1. Reference MIL-L-85762A (Table II).
6.2.2 High Ambient Contrast
Minimum Contrast of the display in a diffuse off-axis illumination of 86,080 LUX
[8,000 fc] and a specular on axis luminance (sky) of 6,853 cd/m
2
[2000 fL] is > 6:1.
Reference MIL-L-85762A (Table II).
6.3 Display Uniformity
Luminance Uniformity (U
L
) measured within 30 mm from edge of the display image area is + 40%
of the luminance measured at the center of the display screen.
6.4 Display Chromaticity
The metric used for color coordinate determination is the CIE 1976 UCS (Uniform Chromaticity
Scale) u’, v’ system.
Color determination is performed normal to the display in a dark room environment with
ambient light conditions less than 10 LUX [1fC] incident illumination.
The measured u’, v’ color coordinates at room temperature for White-light and the Red, Green,
and Blue primaries are listed for reference purposes only.
Color u? v? Perceived Color
Red 0.449 0.517 Red
Blue 0.144 0.299 Blue
Green 0.142 0.559 Yellowish-Green
White 0.215 0.489 Warm White
White color is concentrated around 5600
o
K color temperature.
