Hi All -
I didn't know if this had ever been posted here before. My apologies if its a repeat.
Apparently screen brightness is improved by the application of a thin layer of epoxy.
The other thing that good screens have is very fine pitch Fresnel lenses (about 300 grooves per inch). I searched around a good bit one day at all the likely places (Edmund and various others) and was never able to find a source. Anyone got a dealer? Do we have to get them from a shady character on the street corner ;-)
