Thank you !
I was thinking of the solvent + some pieces of polycarbonate/PMMA "melted " inside to form a thin "glue " (my bonding material ...)
Then I'll use it as thin paint ( as "dry '" as possible ,meaning a lot of phosphor load & solvent ...In order to dry as matte as possible ...)
I 'll use an air-brush ...(Industry uses pulsed spray coatings ..Found out about how they do it ,actually... )....
Maybe multiple thin coatings (testing ...the simple way ... ) of 0,05 mm ,each...
Melted PMMA & phosphor & solvent sprayed at Pmma screen ...
Solvent until evaporates bonds pmma screen and phosphor at a thin layer ....
Another way is using an extra bonding material ..
Be it uv curing silicones ,acrylic or epoxy .....
But I'm not that fond of ...
I prefer the "superficial bonding by critical solvent evaporation "( phewww ...!! What did I just wrote ? )..
Making it "one " with the substrate ...
Any comments ?
Any thoughts about possible troubles doing so ?
$hit ! those Phosphors (specially the red ones ..) are pretty expensive ...
( A phosphor layer would be approx 200 x 160 x 0.2 mm(say... ) = 6400 mm^3 = 6.4 cm^3
Some of that ( 1/3 to 1/2 ) should be PMMA material ......
Say the 1/3 ....
So 4,3 cm^3 is the blend of phosphors (approx ) as powder ....
Average density of phosphors is 3gr / cm^3 ..
So for every panel appox 15 grams of phosphor is needed ?
It can't be ...
Somewhere I did a mistake .... ..
Wow ..That's a lot ..No way...
