The German company Schneider AG was working on a prototype for a laser TV in the 90s. I remember reading an article about it in c't magazine back in the day talking about an early demo where they projected an image onto a bedsheet flapping in the wind with the image, of course, always in focus.
The article also talked about how the color gamut achievable with lasers is much wider than the one available in CRT displays of the day and that the only major roadblock to a commercial release was the (at the time) prohibitive cost of blue lasers.
I was always hoping that the technology keeps getting developed but it seems that it never went anywhere. Too bad, but all the better to see that hobbyists pick it up now that lasers are much cheaper.
This Wikipedia article has some more information:

- julian37 15y agoSorry for replying to myself but I forgot to mention the most amazing detail about Schneider's design: the article was also talking about how you can keep the lasers, cooling, power adapters etc -- basically, everything big and noisy -- in a base unit that can be stashed away somewhere on the floor, maybe under the sofa kind of like you can do with subwoofers. The light from the lasers is piped to a projection unit through glass fibre. The projection unit then only consists of the mirrors and some control circuits and thus can be miniaturized down to almost nothing. So no need to hang a big apparatus from the ceiling like you have to do with the current generation of projectors. (I don't remember if this was actually implemented in their 95 prototype or if it was just on the roadmap -- probably the latter.)
