1950's Tidbits on the development of Early Color TV.

[nasadowsk]

11-1955… GE issued progress report and demonstration of a new type of color CRT. The 22” departs from conventional 3-gun types. The 3 guns are mounted in line rather than a triad. The mask is a set of parallel wires and the phosphors are deposited in vertical striped rather than the current 3 dot patter

So, basically, GE was darn near the Trinitron design, back in the 50's, and blew it.

Also, it's interesting to see the enthusiasm for color TV, when, by the later 50's, it seemed like it wasn't going anywhere, due to a chicken/egg situation for both programming and sales. Set prices weren't helping either, I bet...
