| Aug 7 at 4:44 | comment | added | Tank R. | ...2/2 Despite the potential for X-ray emission, there is no evidence that radiation from properly functioning CRT displays has caused any significant health issues. Was there SOME energetic emissions? Yes. Was it any more harmful than your average day in the rockin 90s? There is absolutely no evidence it was. As someone raised on tubes, and internet that made noise and tied up your phone line, with 6 foot curly cords on the wall mounted kitchen phones, there are zero ill effects from sitting in front of room heater CRTs all day. Can we please move beyond that 'the past was terrible' mindset? | |
| Aug 7 at 4:37 | comment | added | Tank R. | I know its become hip to buy into the 'crts were x-raying our brains!' craze, however as a survivor of all of the 90s I have to address the kneejerk hyperbole and the misinformation it infers. Properly functioning CRT displays emit X-rays at levels significantly below those considered hazardous to human health. Leaded glass in the CRT construction acts as a shield, significantly reducing X-ray emissions. Regulatory bodies like the FDA set standards for maximum permissible radiation emissions from electronic devices, including CRT displays. 1/2... | |

| Dec 23, 2021 at 14:00 | comment | added | Raffzahn | @rackandboneman So, what happens when mixing those three? Or search for others? I do not believe the Wikipedia article does list all known 'phosphors' and even less all possible. Only common ones. And being common isn't determinated by what exists, but what fits a common use cases ... like a nice green with all above mentioned features. | |
| Dec 23, 2021 at 13:54 | comment | added | rackandboneman | I thought the question was about single-phosphor CRTs? You only need three phosphors for a color CRT... so yes, you can do red green and blue well, this is not "any color you want".... | |
| Dec 23, 2021 at 12:48 | comment | added | Raffzahn | @rackandboneman Then, how can a colour TV generate all (well, a lot of) colours, all with a good (and mostly equal) persistence, About the same activation energy for about the same intensity and so on? | |
| Dec 23, 2021 at 7:25 | comment | added | rackandboneman | "Pick any colour you want." not really - in most cases, "Standard Phosphor Types" as documented in the wikipedia article already mentioned will have been in use - these come in a selection of colours but don't really offer a choice of arbitrary colour, especially given that all the phosphors have other properties besides colour, which results in varying usability for computer monitors (too long or too short persistence, or low efficiency/visibility phosphors would be a bad choice)... | |
