As Fred mentioned, projection TVs (I still see them), but convergence
was a headache. The fewer optics, the better. Better to use field-
sequential with a color wheel (as in the old CBS color TV system) as
various computer-to-film systems did.
If you've never seen one, the color on the old CBS system was quite
good--far better than the RCA shadowmask tubes of the time.
