Purdue has one of those at their football stadium - a Sony Jumbotron. Has a
buch of small CRT's they call "cells", which are each a color pixel - three
lines of color on the display, one red, one green, one blue. It doesn't take
a lot of smarts in order to operate one of them.

Wow. I'd love to have seen a picture of that puppy! I wonder how
much power it drew when turned on :-) Presumably you mean 375-475? I can't imagine
displaying 3 lines on a
CRT ;-).
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.
