| "The video makes it seems that there's no temporal bleeding on CRTs. This sounds unlikely to me..." There is, but I don't remember it being noticeable even on cheap TVs, except in high contrast situation where the screen is dim with bright things moving around. I still miss the lack of motion blur that CRTs gave by default. I found a forum post where someone lists these values: "Phosphors in current use for CRT-applications: Red: phosphor = Y2O2S:Eu3+. Lifetime (1/e time) = 150 us, single exponential. Green: phosphor = Zn2SiO4:Mn2+. Lifetime (1/e time) = 10-15 ms. Clearly, this is quite long and is the limiting factor in increasing frame-frequency. Note: the emission decay has a highly non-single-exponential decay --> at long times (~1 s) still some emission can be observed by the eye. This can be seen clearly by looking into the green CRT directly after the image was switched off. However, the intensity is too low to cause problems in an active image when the image-frequency is below ~100 Hz. Blue: phosphor = ZnS:Ag,Cl. Lifetime (1/e time) = ~100-200 us. Note: not single-exponential decay, but no emission at long times. (Source: Shionoya & Yen, "Phosphor Handbook", 1998.)" https://www.avsforum.com/threads/what-is-the-rise-and-fall-t... And in this high framerate video of a CRT you can see the different colors decay at different rates. Here the blue seems to decay the fastest. But they're all imperceptibly dark by the time the scan line comes around again. I have no idea if there's any cumulative effect that's perceptible. https://youtu.be/3BJU2drrtCM?t=153 https://www.youtube.com/watch?v=FhoZzDF3lWU |
In this case, the pinnacle of emulation of a CRT is to simulate photon emission in a tube, and simulate the response curve of each phosphor element.
To do that would probably take a supercomputer to effectively calculate real-time.
According to this paper, there are (1.12 x 10^16) photons per second produced by a 1-lumen source over the interval from 400 to 700 nm . And with a 200 nit CRT is roughly 600 lumen... which is roughly (6.7 x 10^18) photons per second... if you just model them as a particle. To take in quantum effects, yeesh.
