Back when
Comdex was still active, there were a lot of technologies used
for billboard sized screens. One of the techniques that I saw was a
billboard made of thousands of 2" CRTs, using each 2" CRT as a single
pixel. Each CRT only displayed 3 "lines", RED, BLUE, and GREEN.
Wow. I'd love to have seen a picture of that
puppy! I wonder how
much power it drew when turned on :-)
Good question.
A lot of the billboard sized screens had trailered generators. I never
knew which were due to amount of power consumption, v which were just a
lack of convenient outlet.
I would have liked to see the multiple CRT one redone with
software/firmware to present a portion of the image on each screen.
(I want a multi-Giga-pixel display!)
There was a nice "portable" screen made of red and green LEDs.
Now that blue has come down to a reacheable price, that could be
done as a really nice one.
