How to make a cockpit LCD display night vision compliant? I am trying to understand what does it means by making an LCD display compatible with Night Vision? The aircraft is an old Mirage of 1950's.
If I use an LCD display in it's cockpit display unit then how would I make the LCD compatible with Night Vision capability?

Do I need to select a specific color (wavelength or frequency on spectrum) to display the data on the screen?
Or do I need to put some filter sheet on top of the LCD screen to make its Night Vision compatible?
Or does it mean something other than these?

Edit:
The only info about the OEM display is follows:
&quot;The display is an ac TFEL flat panel display combined with contrast enhancement bandpass filters to achieve both sunlight-readability and night-vision google compatibility&quot;
I want to replace this TFEL display with an LCD display. But I dont understand how will I do night-vision google compatibility in an LCD?
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.
