DISPLAY PERFORMANCE
6.0
6.1
Display Luminance
The display provides one level of luminance used for both daylight and night viewing.
Minimum white-light luminance at the screen center of the Monitor face is 1500 cd/m
darkened room environment with ambient light conditions less than 10 LUX [1fC] incident
illumination and at room temperature. Reference: MIL-L-85762A (3.10.2.2.3). Luminance
specification applies to the initial luminance, i.e. prior to additional operation in the end system.
6.2
Display Contrast
Display contrast is a relationship between luminance levels and the ability to perceive a luminance
difference. It is expressed as a ratio of ON white – luminance to OFF black background luminance
generated by the display.

6.2.2
6.3
Display Uniformity
Luminance Uniformity (U
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.
