We're on the Devil's Treadmill. You covered this relationship a year ago. Endorsed by the U.S.Army and Karl Guttag and yourself. Very cool.

Guttag had a chance to talk to Fellowes and he chickened out. But he concedes. Yes, high likely. I didn't notice, belated congrats. Maybe we can get a Guttag fanboy to put it out there.

Karl Guttag :

Yes I saw the video. You probably know IDVS is WUXGA (1920×1200) and that eMagin happens to make an WUXGA device in a military version. For night vision you don’t need a lot of nits and black level is very important. Along with the other information, it all adds up to it being highly likely that the IDVS is using an eMagin OLED microdisplay. So it looks likely you will “get your wish” that Rockwell is using eMagin for this product.

It is also interesting that some recent patent filings for waveguides (WO2016130509 and US20140140654) are joint between SGB-Labs/Digilens and Rockwell. This might suggest they might be using SGB-Labs for waveguide technology.

You can couple OLEDs to waveguides, but it is not clear how well they work. Its very hard to get any objective data on waveguides (“little things” like coupling efficiency and spectral requirements/performance). You might get a lot of “waveguide glow” but this is not as important for very sparse content on a night vision HUD type display. You are not trying for “movie quality” but rather just providing key information.
