How to make a cockpit LCD display night vision compliant?
You can make an LCD screen NVG compatible by adding a filter screen on top of the display that complies with MIL-STD-3009.  You can get a copy of MIL-STD-3009 from several commercial sources or direct from the Defense Logistics Agency website.
There are a few companies that manufacture the filter screens. I would start with a search for NVIS filters.
