Section 6 – Display Performance
6.1
Display Luminance
The Display will provide one level of luminance used for both daylight and night viewing. Minimum,
initial, white-light luminance on the face of the Display face shall be 685 cd/m
room environment with ambient light conditions less than 10 Lux [1 fC] incident illumination and at
room temperature. Reference: MIL L 85762A (3.10.2.2.3).
6.2
Display Contrast
Display Contrast is a relationship between luminance levels and the ability to perceive a luminance
difference. It is normally expressed as a ratio of ON white-light luminance to OFF black-background
luminance generated by the Display.

6.2.1
Room Ambient Contrast
Minimum Contrast of the Display under room ambient lighting conditions of 1076 LUX [100fC] direct
incident illumination is 11:1.
Reference: MIL L 85762A (Table II).
6.2.2
High Ambient Contrast
Minimum Contrast of the Display in a diffuse off-axis illuminance (sun) of 86,080 LUX [8,000fC] and a
specular on-axis luminance (sky) of 6,853cd/m2 is 5:1.
Reference: MIL L 85762A (Table II).
6.3
Display Uniformity
Luminance Uniformity (UL) measured within 25mm [1.0in] from the edge of the Display image area is
±70%, minimum of the luminance measured at the center of the image area while displaying a center
block pattern measuring 50mm [2.0in] square.
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 at the 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.
