I need to be
able to cover fairly large areas with some kind of display technology
at a resolution no worse than about 75dpi. Since "large areas" means
dozens of square feet, too large for a CRT, all I've been able to think
of are LEDs. But I don't know how practical (or more likely how
drastically impractical) that is.
There is a company in the Detroit area (Daktronix) which makes large
displays using leds. I saw the "panels" being made one day.
So it's very practical. (and I believe there others who do this also)
It seemed to turn into an interconnect and testing problem... e.g. most
of the problem was one of interconnecting the panels and testing them.
(personally I would have redesigned both their display and their
manufacturing process, but that's another issue :-)
