I have a sci-fi world that is very technologically advanced (at the stage of "sub-singularity" where they have already invented AIs posing danger to humans, but not achieving singularity, so it's not God-like and can be fought etc.). Both humans and the machines (so far the only inteligent "races") use technology. I want to specifically concentrate on the human technology regarding displays - are there any advantages, and could there be any advantages to use Cathode-Ray Tube displays, i.e. on a spaceship, despite the general inferiority of such display to LCD or plasma. Of course the old cathode screens "sucked" in their flickering, glitches, and image quality. But could there be some reasons, why their use would still be a good option to consider. Particularly in the military-utilitarian uses (similarly to how military planes and civilian planes differ) or industrial uses.
I was thinking about potential costs. Could it be that on some planet the cost of producing the liquid-crystal display is to high, because of material shortage? Could there be some other advantage to CRTs? Are they used anywhere right now in professional industries, for other reasons than "not yet replaced"?
I want to stick extremely true to physics as well as present a reasonable, believable future (meaning no "laser guns" shooting visible "laser bullets", no "telekinesis", at least without a good, scientifically correct explanation for it). But I also want to world to be consistent in terms of economy (at least to some point), people's choices etc. So if there are to be CRT displays, they need a reason to be there.
Finally: why do I want to include them? Cause I like the glitch effects, and generally their style. Already military ships will use terminal akin to the ones often used in linux systems - but this isn't "forced" retro, because I personally believe that the terminal is the best way to use a system ;) Anyways I can find justification for a military spaceship depending on an old-school terminal interface instead of some "touchscreen" stuff, but cannot find justification for using CRTs instead of LCDs.
EDIT: Thanks for the current answers, but I'd like to mention that the world I am describing is "our" world a number of years in the future. Interplanetary flight IS possible, common and even somewhat easy (the technical explanation for this exists, but I shall not go into details here). However we have to take into account the current human achievements, so LCD is or at least has been known. I guess it could be possible that some factory on planet XYZ which produces spaceships, got very very old design, and copied it. Or maybe the machines (which are quite a diverse, and active race) have been designing the spaceships for humans, but downloaded the easiest to find blueprints?
