Oh wow wasn't expected this thread to get resurrected. They were progressive. I did find out that the crt gets reduced sharpness (and hence reduced contrast?) at higher bandwidth. Not sure if the two are connected as I am skeptical on if I can notice such differences between the low bandwidths I...
Are there materials or mechanisms that allow electrons to pass through a gate unimpeded but block photons? That would make a solution really easy. I don't know much about photons and electrons, but I know they have different wavelengths. Can that fact be used to filter one but not the other even...
I've done a good amount of textbook reading on crt tubes since I last posted and acquired some better tubes. I still have a few questions though that I am not sure about.
First off, how does the color sampling aperture affect the maximum resolvable resolution? I read exceeding pitch is like...
Here is the prototype. It's just a video demo though.
The wiki for sed, which probably has inaccurate info because it's Wikipedia: https://en.wikipedia.org/wiki/Surface-conduction_electron-emitter_display
but that is probably too general for you. I found this more technical explanation as...
I ask because I was looking into the fed/ sed display tech that was going to come out in the late 2000's, which had a electron emitter for every single subpixel. There is a 720p prototype you can see on YouTube. Wikipedia states it would allow for increased brightness due to not needing to steer...
Also, what physically happens that causes crt burn in? Could a phosphor generate x10 the nits but be exposed to the beam for a much shorter time and be just fine in turns of damaging and burning the phosphor?
I actually am wondering, if I want to get more brightness out of x amount of phosphor, is it impossible to get y amount of brightness without z amount of acceleration voltage? Does that mean making any type of crt with higher brightness would be dangerous due to acceleration voltage generating...
The video I watched about modern analog computing was this:
The guy in the video claims modern digital computing chips were 1-4x faster than the chip they currently had but the chip they had only consumed 3 watts.
That company went bankrupt last I knew.
Okay so modern displays seem to not be able to reach super high refresh rates for the clarity it affords. Do you think this is due to a limitation in how fast the logic can refresh the screen or could it be done if the manufacturers felt so inclined?
I feel like this is probably a dumb question...
I'll admit I'm also getting tired of video games, only some that stand out catch my attention nowadays. But that is just it, we need super high refresh rates to lower blur from sample and hold, it's a fundamental flaw with it. Yes, more refreshes results in a more continuous image but the...
Plasmas supposedly scaled poorly in terms of power and weren't power efficient enough at higher resolutions to pass regulations is something I read on the internet. You are right that plasma might have been the solution if only we'd have used faster decaying phosphors. Plasmas that were sold...
I hope so but it's been two decades of having a literally worse image in motion than what we had at the super high end crt monitors and while we have 4k now we still haven't caught up in motion resolution, which is kind of the whole point of a display.
I know there are theoretical ways of...
Are you saying I need to make a second thread specifically for motion? I'm probably close do done bugging you now. There's not much more I can ask. Well, that's not true I could probably talk your ear off asking questions about crt but I won't.
Also, in relation to motion horizontal/ vertical...
What exactly do they need a crt for? Are you saying you don't believe the assessment that the visibility of a pixel reduces the perceived motion blur? I have a 144hz lcd and setting to different refresh rates of 60/100/144 definitely allows me to set that ufo test faster without blur and it is...
