@@monkeycoder7368 Hi. I am currently studying electron microscopes, which uses essentially the same technology. The early electron microscopes, thus I would assume this holds true for early CRT as well, used Wolfram/Tungsten for making the filament. It later moved on to LaB6 The difference in colours? Red colour is 1,8 eV and Blue colour is 3,1 eV, so the difference would be how much energy is sent into the filament Keep in mind that their 3d model is very simplified and does in fact lack some components
OLED screens draw line by line as if it were a cathode ray tube, so when you record an iPhone or Samsung Galaxy at low brightness, flashes appear as if it were a CRT.
Fun fact, CRTs usually aren't perfect! The workers often have to tweak things to get the beams lined up just right, so when you turn on your new monitor the picture looks good!
even more impressive is that since 60hz is just barely slow enough to be flickery when viewed in computer monitor distances, crt monitors often ran even faster than that, often running at 75hz by default but some running at 85hz or higher!
Using CRTs 8-12 hours per day from 1976-2008 does not seem to have harmed me. Don't smoke, wear your seatbelt, eat decent, and get enough exercize. That will cover 98% of the risk factors that are actually worth taking into consideration.
@@neerajdubey7481 Whoa apologies for the late reply.

They mention 60 FPS for simplification, but the field rate was actually 59.94, PAL regions were lower at 50 FPS, and higher end CRTs could go up to 121Hz. That's 121 passes a second. Fun fact: CRTs displayed interlaced images by default to reach 60fps, so 240p combined every other field of 480i and cut the FPS by half, giving us the 30fps of 80's and 90's video game systems.
I really understand the deflection of beam....before seeing ur video i can't imagine and understand that how the whole screen flashes......thanks so much.....
@BranislavDJ The older black and white screens had little protection and have caused many cancers and deaths. Tv repair was a dangerous job! They have since realised the issue and put radiation protection in tv's. What happens is the larger tvs need a stronger electron beam and a more powerful yoke, sometimes and 30k volts(reason why 26" was a plateau)!! Lots of x-rays! However, even with all the protection, if you held x-ray film in front of any TV, over time, you would see a result.
Anyone wanna tell me that this was not WAAAAY better than all LCDs to date, excluding oled? When they made a switch to LCD cause "science" and "environment" I could not believe how shitty it was, especially for gaming.
it's due to the Hz (Hertz) , it's how many the 3 Electronic guns produces the RGB colors per one second For an example ,My CRT Monitor , works at 1280x1024 At 60 Hz And that means , the three electronic guns produces the RGB Colors 60 Times per second at 1280x1024 Resolution And the maximum supported resolution is due to the Shadow mask rendering ability
The magnets don't physically move, they use electromagnetic coils, which vary the magnetism by the amount of electric current applied. This change in magnetism causes the electron beam to bend in different directions
Because a colour CRT is only limited by the number of phosphors / holes in the shadow mask or aperture grille, and there are (I am told) many more phosphors than there are pixels. Hence, a quality CRT can resolve any way you like! I remember the last CRT monitor I had (which came with my 2002 Dell Dimension), which I believe was 17 inches. It was not the highest quality monitor, and while it worked fine at its native XGA (1024x768), it really did look blurry at VGA or SVGA (640x480 or 800x600) Thankfully, I have an IBM ThinkVision C170 CRT in the mail, which can apparently display up to 1600x1200! (more than ample for my purposes!)
Because crts have a maximum output range in khz, but no native resolution. An lcd has a native resolution and any other resolution is just upscaled to your monitor's native resolution
Ok, then what? What would happen as a result of electron guns shooting bullets? You see the word gun and don't infer that it doesnt mean the ar-15 kind?
And i tout that pc crt monitors were progressive, but i am wrong because it generates the image line by line, but it happens sooo fast that we just see a complete image.
it is progressive ! interlaced would mean that every second line would be skipped from frame to frame. you could have and array of small leds that can all flash up at the exact time, and make it display interlaced video. what you are thinking of, is rolling shutter. if you have a decent camera it will shoot 1080p (progressive) but most likely the pixels will also be collected line by line, but because of the p no line will be skipped
CRT doesn't have pixels, but pixels are made by three subpixels (Red on the left, green on the middle and blue on the right) and is smaller than phosphor dots in a CRT TV/monitor
For retro gaming, only ever a CRT. Don't bother with xRGB scalers unless you dig artificial scan lines and no light guns. If you want luxury, go with a PVM. For affordability, get an RGB modded Trinitron TV. For PC gaming, SONY has a 1080p CRT PC monitor (GDM-FW900). But for practicality and affordability, a 4k Vizio TV for living room PC gaming setups is ideal. I have tasted oLED and it tends to have issues... Definitely not gamer friendly (almost every oled washes out be it months or short years later.)
I see your 2020 & I raise you 2022. Oh, & I watched a BBC Four documentary film from 1939 on a 4:3 CRT this morning *&* I watched multiple episodes of Will & Grace on the same device last night.
Yes, which if the monitor is running at 640x480 (which is typical for monitors that support 160hz), that means that the electron beams move to 49,152,000 individual positions every second!

CRT's also have a form of glass that is mixed with lead, which has enough stopping power to keep x-rays from reaching you to a measurable extent.
The lead is harmless though.

Electron beams don't have any colors. Its actually screen coating which produces colors.
They actually describe that at 0:44.
When they describe the electron gun, they dont actually specify that the beams themselves produce the color.
I don't get it, are all the guns the same thing as each other no difference?
@BranislavDJ The older black and white screens had little protection and have caused many cancers and deaths. Tv repair was a dangerous job!

It blows my mind. How did they make the magnets so accurately move the beam in a straight line back and forward so incredibly quick?
It's just like a human eye vision mechanism but reversed
SOMEONE FINALLY GETS IT!!!😊

@@idkrossplay would be great, but try oled my friend, they are totally decent, finaly some depth.
@@mrthoms0n1 yes but no scan lines
People switched over to LCD because CRTs are massively bulky.
@@mrthoms0n1 OLED is nowhere near as reliable and only has the same color goodness as CRT's.
That's actually very clever
so... it's magic? ok got it. magic.
how is it possible only 3 light emitters to light all the pixels on the screen and do that 80 times per second
mask mix the light red green blue
it's due to the Hz (Hertz) , it's how many the 3 Electronic guns produces the RGB colors per one second
For an example ,My CRT Monitor , works at 1280x1024 At 60 Hz
And that means , the three electronic guns produces the RGB Colors 60 Times per second at 1280x1024 Resolution
And the maximum supported resolution is due to the Shadow mask rendering ability
wow
hahaha yes
Thanks, do you have the name for the color guns?
Its happens so fast that you are unaware of the firing process and the result is a steady picture
Rolling shutter effect: we’ll see about that
Good video
Interesting
if you have 1million pixels and use 60hz, so the gun can switch targets 60million times per second?
There's now a flexible display. yeah, I'm in the future
Oleds were around in 1987 so this video was made way after those became a thing
but how its so synchronized and how magnents can work that fast every day, the wole day for years without getting broken?
There not magnets. There copper wire, the electric goes into the copper and create an magne
The magnets don't physically move, they use electromagnetic coils, which vary the magnetism by the amount of electric current applied. This change in magnetism causes the electron beam to bend in different directions
@who am I ?? From the analog signal of the input being fed to it
i prefer a crt display.
no you don't
As a matter of fact crt monitor are better... they dont have any input lag
You dont prefer that heavy, bulky and potato quality crap.
CRT's are just freaking cool on oscilloscopes, especially because they are not too hard to carry.
so you also prefer glasses and headache?
hmm --- I was wondering where the frame buffer comes into play.
niceeeeeeeeeeee video
good
they underestimate power of CRT's, mine works at 120hz rn

but why could we change resolution that easily ? With LCD screen, it's almost not possible, I mean the quality becomes really bad.
