My high school tech courses are still teaching these despite most of us already having plasma TVs and a digital cable box. Hell, they still describe the internet as connecting it through the phone line like it's 1998.
I remember this video from when I was a kid and we had just added a CD-ROM drive and Soundblaster 16 to our family computer, Grolier's Multimedia Encyclopedia came with it
Not necessarily. The refresh rate of the television screen depends on the amount of time that it takes for the phosphor dots to dim after being struck by the electron beam. As you may have guessed, this varies from television to television since some compounds, such as the mix of zinc cadmium sulfide and zinc sulfide silver that was used in black and white CRTs can take as long as 1/30th of a second to dim down while phosphors commonly used in modern CRTs can dim down is as little as 1/100th of a second. Granted, such a high refresh rate was only seen in very high-end televisions and modern OLEDs can have a refresh rate exceeding 300 times per second, the refresh rate depends on the the television.
+volarecantare No, it's the flyback transformer that creates the high voltage. The shadow mask / aperture grille (depending on the tube type) is charged to 10-30 kV which creates a huge potential difference between it and the glass envelope which is (hopefully) grounded. The color cathodes are almost always less than 50V unless you have a massive tube. The larger the tube, the larger the cathode and flyback voltage will be to maintain an adequate brightness on the screen.
Illumation Streambutler If it had a smell similar to burning brakes then it was some IC that got sad and went off. Sometimes excessive dust can cause weird smells and CRTs are like dust magnets due to the high voltages.
No, CRT television scannin isn't interlaced. CRT tv's are a video output that refreshes the whole image, every single line, 60 times a second (50 if you're in Europe). Interlaced video is the source or input that was to be displayed. You could display a progressive scan video on a CRT without an issue (at least not caused by the tv monitor itself). Just an example: the fist time I watched a 720p video it was played on my CRT computer monitor back in 2005, when I downloaded an Apple movie trailer (they just started offering their trailers in HD). Well, actually, I think all Apple movie trailers were encoded in progressive scan way long before that even if they were low resolution.
@Ian Stevenson But you're confusing what channels broadcasted with the actual capabilities of CRT televisions. CRT was able to display progressive scan video, just like videogames running at either 50Hz or 60Hz depending on the region (mainly PS2 era).
nope. the light beams [correction = electrons] fire through the shadow marks and the the phosphorus has a chemical on it which if a color reflect on it will glow. depending on how high th electron volatge is, the phosphorus will glow as much as the electron

I'm utterly fascinated by CRT televisions, as a retro gamer and a cartoon connoisseur a CRT is a must.

I will always love CRT’s better than flat screens.
Me too
What about flat screen CRT televisions? Most CRT HDTVs are designed with flat screens.
CRT filters are cool. CRT’s were cool back then but out with the old in with the new. They took up so much space anyways.
I have learned, thank you
Is just like a human organs how our lens actually works is almost like a crt tv
For the newbies, the CRT tvs or monitors got 0ms inputlag.
Plasma stucks at 0,001ms inputlag. The New OLED TVs is pathetics 15ms in game mode....
You are "pathetics"
Actually it is at 60 times a second or 60Hz

This looks like it was made in MS PAINT
Which makes it better
That’s why my iMac g3 studio display’s screen is so hot😆
Electron guns. Is that what made the screen so electrostatic?

There was also a smell, i cannot describe it, very light smell like a laser printer but softer. hmm, any ideas?

Isn't the scanning supposed to be interlaced in CRT tv's? IN this example it looks like it's going line by line sequentially without skipping.....

Thank u
i indeed do watch some guy talking with the text "TV" as a square next to him
Super
A kép tisztasága és minősége pedig a szűrőtől függ.
So both the light beams and the phosphorus is colored? Seems like overkill.
nope. the light beams [correction = electrons] fire through the shadow marks and the the phosphorus has a chemical on it which if a color reflect on it will glow. depending on how high th electron volatge is, the phosphorus will glow as much as the electron
It looks faster than my 7th gen i5 processor pc😯
when did green become primary
Cody Hyde because *green is a creative color!* lol
Maybe since Isaac Newton?
Since when was green a primary color?
Hmmmm... CRT TVs aren't technically Cathodic TVs, right?... CRTs have a sloghtly different way of fonctionning, right?
480 lines at 30 times a second
