[comp.society.futures] Projection as screen replacement

orr@taux02.taux01.UUCP (Orr Michael) (01/26/89)

does anybody know of any attempt to use a projection system instead of
a screen ? seems to me you could have a tiny LCD-shutter and project
through it.

I've wondered about this myself.  One of the problems with a large LCD screen
is that the yield on LCD's bigger than maybe 13" is currently lousy.  If you
could project the LCD-generated image to a larger screen, the LCD panel itself
wouldn't have to be very big.  

What I don't know is what the lower bound is these days on the size of LCD 
"pixels".  I.e., if I want a 1Kx1K pixel display projected from an LCD panel,
I'd have to have 1Kx1K LCD pixels in a very small area.  Does anyone know how
small LCD dots can get?
