It sounds like they are just using the gold NPs to absorb/filter out a particular wavelength band. The glass is tinted the right color so that color doesn't pass through the glass to the eye.
If you replace the NPs with QDs, then won't you get the opposite affect? The QDs absorb the incoming photons and then emit photos of a specific wavelength based on their size. If the QDs are all the same size, then you render everything in one color.
If the QDs vary in size to produce all the colors except the one you want to block, doesn't that randomly distort the colors of the image. Wouldn't you need to pixelate the QDs like an LCD screen, which leaves you with something like Google glasses?
I think the use of the NPs makes it simple and cheap by just being selective filter.
