CRT displays are still being made. These are small for specialized uses. They are still being refurbished too.
To me, a good plasma display offers a lot of what people like about the CRT. Phosphorus glowing in tubes are fast and high contrast. And maybe the micro-LED displays will be similar. Pixels lighting up, are still nicer than trying to block always on bright light.
Those things said, people like the CRT.
One mounted in a cabinet, for example, will deliver a really compelling experience! About the only thing I can see competing is a laser projection of some kind.
Really high refresh, interlaced CRT rasters have a look too. So does higher refresh rate, progressive scanned motion.
Maybe this ends up like vinyl. We have not lost the tech yet. Maybe there will be a return like we have seen for vinyl.
And here is an idea for someone:
Make the shadow mask on glass and enclose it in a vacuum, but not big like we need for an electron gun. Just big enough to enclose the phosphor.
Then, from the rear, excite the phosphor with lasers. Or even a few groups of them to get a full, high speed raster made up of multiple smaller ones all running in parallel. Think 4 rectangular displays stacked together with their longer edges touching.
Doing that keeps the deflection angle down.
And the lasers can be enclosed. But it won't be necessary to pull a high vacuum for the whole thing. Just the thin, front, phosphor portion. And that could be replaced when it gets tired, and or when burned in, or scratched up.
Registration becomes a software problem.
Good displays have .01x inch phosphor dot pitches. Violet light is orders better at 0.000015 inches. Light just outside visible would work great.
The phosphor glass assembly could be recycled or refurbished and relaxed vacuum requirements means avoiding toxic glass.
I bet a display like that would deliver the CRT experience and then some.
Someone go make the thing. I want one.
Or, maybe I hit the lottery! Then I will make my own.
