flat CRT

right. thats why I was thinking if one could make miniature sized crt like devices then one wouldn't need as strong magnetic fields(or electric). I suppose that there still has to be a minimum energy of the beam to interact with the screen to produce light so there might be a practical limit that one can shrink it.

Just an idea. Surely you can't fault people for trying to be creative? Also who can really say what is worth while and what is not? For all practical purposes a new born baby is a waste of time and resources but yet there are lots of people that bother with them.

Of course you "can't fault people for trying to be creative," but the point was that everything you've mentioned (and more) has already been tried in the 100-year-plus history of the CRT. And as to the question of "who can really say what is worthwhile and what is not" - the question of whether or not any of these notion was "worthwhile" has already been answered by those in the industry who tried them. The fact that you do not see any of these concepts remaining in production (and very, very little ongoing R&D efforts in CRT technology of any kind) is telling evidence that this field is, at this point, pretty much played out. It's not QUITE to the point of "you might as well be working on a better buggy whip," but it's getting pretty darn close to that.

"Original idea is flawed"?

Tell us what you have invented lately.
