if the 3 beams were miniaturized as in surface mount diodes:

these for example

and were carried or fibre coupled in a single "gimble?" there would not be duplication of moving carriage parts. a "trinitron like" emitter gun would be possible. moving a mirror as done by the author would also reduce the mass that would move at high speed while scanning across a large display field, it would then be a matter of timing a laser pulse of desired color to the desired position of the mirror set. a look at CRT television/display circuitry would be very inspirational, only in this case the color is emitted rather than stimulated by flouresence of a phosphor target.

Something to keep in mind is that mirror scanning for television is a very old technology, dating back to the beginnings of mechanically scanned TV:

Yes. There's a long history of ideas in this space. DLP projectors, with a MEMS mirror for each pixel, are one of the few successful examples. Any system where you illuminate only one pixel at a time flickers horribly, which is why this sort of thing is used for laser light shows and not much else.

- now if you can send the beam[s] through a tft display minus the backplate, and darken pixels you dont want to illuminate then scan the beam across the whole thing...This has a madmax or a maxheadroom sort of appeal to it.

i was trying to find the mems mirror around but couldnt , still looking for dead projectors to throw in the morgue of parts.

I do have wide streak of steampunk, i love retrotech, espescially when using junkyard parts and a few mailorder bits together.
