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

 [200 fL] in a darkened 

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.
