OLED Target and NVIS Green B

Can a green monochrome OLED meet both a customer chromaticity target and the MIL-STD-3009 NVIS Green B color requirement?

Find the physically realizable overlap

Using the FPD.DEV calculator, this animation starts with a CIE 1976 u′v′ target at (0.09600, 0.57600) and tolerance radius 0.06000. After a brief comparison with NVIS Green A, it isolates the intersection of the target circle, NVIS Green B, and the physically realizable chromaticity region.

The largest inscribed circle identifies an approximate maximum-clearance chromaticity: the point with the greatest minimum distance to the boundaries of that intersection. This is a geometric design aid; an actual OLED must be measured.

The inscribed radius is conservatively rounded down. Distance is measured in u′v′ coordinates, not ΔE. No sRGB gamut restriction is imposed on the monochrome OLED.

Color and NVIS spectral compatibility are separate requirements

NVIS Green B is a color designation; it does not by itself establish Class B NVIS compatibility. The video plots the Class A and Class B spectral-response weighting curves directly from MIL-STD-3009 Tables IV and V, then shows the separate monochromatic-display radiance limits in Table III.

Passing chromaticity does not guarantee passing the NVIS radiance requirement or an emission cutoff requirement. Measure the emitted spectrum, apply the relevant NVIS response weighting and test luminance, and compare the resulting NVIS radiance with the applicable limit. The response curves are not OLED emission spectra or pass/fail envelopes.

Table III lists 1.71 cd/m² (0.5 fL). Section 4.3.5.9.1 specifies 0.343 cd/m² (0.1 fL) for displays without gray-shade capability. No measured OLED spectrum is supplied in this example.
