I think many people probably already knew most of what you explained in this video (scanlines, RBG pixels, etc.); but to actually SEE it demonstrated so precisely with super-high-speed and macro-lenses was truly fantastic. So much different than a normal #SlowMoGuys episode, but this one might honestly be my favorite. GREAT work, Gavin!
I am electronical engineer of crt TV's for 20 years,and this is my first time in my life who i saw how it works an old crt television! Thank you very very much Gav!
I don't think people realise the level of technology that went in to crt's, compressing 6 signals into one waveform was an achievement in itself (colour tv). Was nice to see what we knew in real time though..
I read up on the development of both NTSC and PAL in the 90s. They were a huge achievement. NTSC allowed older black-and-white TVs to still view the new color broadcasts since B&W TVs would ignore the chrominance line and only read the luminance line while only losing .03 fps in framerate on both color and B&W TVs. PAL, used primarily in Europe, Africa and most of Asia, had slightly higher resolution and was configured in such a way that signal degradation caused loss in saturation (intensity of color) rather than the hue (shade of color). This led to a better-looking picture in many places.
I'm surprised you never seen the effect on a CRT before. Growing up working on CRT TVs, my dad taught me how to manipulate the control circuits enough to slow the scan-out down to strips roughly an inch long. We did so by simplifying the circuit so that it would strobe the cathode ray repeatedly over the same segment but at such a slow intensity that persistence of vision doesn't work thus allowing you to see the scan out. It was thanks to those early experiments in my life that I developed a very deep and almost intuitive understanding of how displays create color, motion and the various other higher level illusions. All I really needed to supplement that knowledge was a relatively light study of how the human eye perceives color, intensity and motion. I doubt I would have taken to pixel/fragment shader development as well as I did without that knowledge, a lot of the ways I pulled off fancy effects in the mid-2000s relied on these illusions.
My father was a TV repairman and electoral engineer. When I was thirteen, he explained to me how a CRT tube worked. I understood it but could not picture it in my head. Thanks to this channel, I saw it for the first time. BTW. I am Sixty-One years old now. Our brains run so s l o w...

Deeney Im a small youtuber and I don't care about the money but getting videos monetized is like this feeling where you can finally make money off of what you love even if it's a dollar it just motivates and inspires me that what if one day I can make a living out of what I'm passionate about and I get to sing and write songs all my life instead of being a doctor or an engineer just like my parents are pressuring me to. I hit 10,000 views 3 months ago and youtube said my channel was still under review and they'll tell me in a week and it stayed that way for 3 months and now youtube says i need 4,000 hours FOUR THOUSAND HOURS i make 4-5 min videos How many videos should that be. This is so frustrating when i found out i felt like crying because it puts into perspective how small i am and how not good enough I may be and it's so sad. It slightly demotivates me and makes me think twice about my life-long held dreams. I don't know why youtube is becoming this sad place Oh by the way it's my birthday and I'm upset lol
This has got to be one of the best videos you have made. It was both entertaining and informative. Granted you had me with the soccer ball (OK I'm an American) to the face, and a sword going through water bottles is entertaining and does have educational merit. However, something like this video touches on real life experiences and reveals things our unaided eyes could never grasp. Thanks for the great job. Slowing down the little things we encounter in real life so they can be properly observed and better understood is a gift you give us all. Thanks.
i have to agree. i have ALWAYS wanted to see the horizontal scan of a CRT ray. i had seen the vertical lines being built before but never this. awesome.
When you think about it its actually not much more complicated than a regular camera, you just need to capture video at 100s or 1000s of frames per second rather than 60 or 30, then just play it back at 60 or 30 fps. You could do the same with a regular camera, but you'd lose a lot of detail in between each frame and it gets quite choppy below 20fps.
I really wish we had this video when I was in radio and television broadcasting class, sadly they don’t offer that anymore at the school I went to. This is one of the most amazing technical videos I’ve seen in a long time.
actually pretty accurate, another example of this is the crashcourse channel. Certain nationalities for one are pretty much censored in classes like primary school education, it's not until secondary education that you get to study them, at a cost, so many dont.
It's ya girl T would agree with you. Education from school is the basics. It's up to the individual to continue and grow. Calling people sheepole or drones is just showing that they don't understand what's going on. Science is truth.

the best BASIC explanation how a TV works....its soooo amazing to think that how a basic day to day thing in our homes like TV works with so complexity and we dont even consider it...by far my most favourite video of 2023
I haven't heard the high pitched squeal of a CRT in years. Ah, the sweet sound of childhood. Also OW MY EARS! Thanks for watching this video, guys! - Gav
My lecturers at college - 40 years ago - would have had loved this technology. Them trying to explain how an interlaced, 50Hz image is produced on a CRT was a nightmare to understand. LOL
geoffphuket same here.. It blew my head off when trying to understand the different screens and the evolution from CRT to LED. Would have been lot more easier with this video to understand.
The one thing that amazes me the most about CRTs. Is that there is a Bi-Polar Junction Transistor switching thousands of Volts which moves that beam around to scan the image tens of thousands of times per second. It also amazes me we commonly used an electronic device which can bend light with electromagnets with extreme precision and none really cares.
+RogueRAZR Well, technically it is an electron beam that is being bent, rather than light, but yes, people back then had just as much ingenuity as people today. We've just learned how to do more things over time--we're not any more clever than before.
Thank you so much for the epilepsy warning. I didn’t watch the video :(, but that warning saved me a lot of suffering. Most people don’t think to add such things. You are very considerate. :)
JellyMan3634 I don't mean to be rude, but that is an ignorant comment. I don't know much about epilepsy, but I'm sure even a small bit of flashing could set someone off. I would encourage you to think before making comments about medical conditions you know nothing or very little about.
Lmao I’m 18 and that was like my childhood. And then when you had the tv on you could hear that really high pitched hum. I heard it in this video and it still hurts my ears lol
It would be interesting to see the arrangement of red, green and blue subpixels on different screens because even different OLEDs use different arrangements.
Yes! I wanted to see the fully lit arrangement on that OLED LG TV. Even when only partially lit, you could see that they are not all the same shape and size like in the LCD. I don't know if this is a PenTile arrangement or not, it would be interesting to watch.
5:06 A couple of weeks ago I was watching a Nintendo NES hardware video, and I was amazed how something so old can do specific calculations, switch banks, etc, depending on the specific scan line that's being drawn. It was something like, on scan line 23 switch to this bank to get this sprite, then on line 27, switch back, 35, etc. It's a full world when you slow things down and realize all the activity that's going on.
Super cool video. There's such a wonderful magic to seeing how that all works. Especially 3:03 when it looks as if a retro computer or TV is drawing an image with each digital stroke across the screen 😊🥰
Our screens generating light, recreating light captured from this video and transfered trough light in fiberoptic cables. light mirroring light trough light.
This is great, I learned about CRTs long ago and never could get my head around how a single electron stream could light up the entire screen with different colours at "the same time", I now know
7:35 that is really cool as a TV repair tech it's awesome to see RGB (red green blue) pixels, i uploaded many tv repairs but never seen a LCD screen under a microscope.
I feel like CRTs were magic for the time, I seriously wonder how they managed to get this level of accuracy and speed with the technology available at the time, it blows my mind
I totally agree, honestly its really funny that humanity invented 'gun that shoots electrons that are then aimed by magnets at a screen' before 'several tiny lightbulbs that dim and brighten' like one of these seems infinitely more complicated than the other one, how did the electron gun come first??
@@commandrogyne LCDs are liquid crystals that rotate polarised light, controlled electronically with backlit regions. This is much more complex than a CRT. Only now with OLED, are we using the 'several tiny lightbulbs approach. The production of something with so many parts is much harder than shooting electrons at glass.
Wdym with the technology available at the time? Do you think they were some kind of primitives using rocks and sticks to build TVs? Do you think the tech we have today just spawned in? Lmfao
... and then one day you realize that ~80% of information taught (at least in elementary / high school) is - if not forgotten just mere months after "learning" - redundant, outdated or incomplete for when you need it, or outright wrong. And that the 20% which is useful could have been learned much quicker and in much more enjoyable way. School is, I'd argue, mostly just an initiation ritual to servitude.
Really cool video! Thank you. One of my early memories is from 1975, aged ten, explaining to the rest of my school class how a colour TV worked. I've always found it fascinating, though of course back then it was all CRTs.
What if i Rec this video in 0.25x speed , and then i apload it on TH-cam and you watch in 0.25x speed ,and you Rec my video in 0.25x speed and apload it on youtube and i watch it in 0.25x speed ,and i Rec your Video in 0.25x speed and then i apload it on youtube and you watch it in 0.25x speed and then you Rec ........
If you pause the video at 8:19 and shake your phone (or whatever it is your using) you can actually see the individual pixles turn White instead of red green and blue!!!
This is amazing!!! I never knew that they were shown in strips! I thought the entire screen was lit up all at the same time! Wow! Seriously, this is awesome!
actually, flat screen tv's have existed since 1964. they were more expensive at the time, so didn't become mainstream until the early 2000's when they were affordable. even other technologies were around before the most of us knew about them. like VR for example. they began working on that in the 80s. just because they're back in time, doesn't mean they're not going to be as creative minded, and ponder of such technologies. even before 3d games, they already had 3d graphics with algorithms to apply smoothing to the human facial expressions they were animating. the real genius's in the world, have more stuff going on than what the majority of the outside world knows about.
I think many people probably already knew most of what you explained in this video (scanlines, RBG pixels, etc.); but to actually SEE it demonstrated so precisely with super-high-speed and macro-lenses was truly fantastic.

RogueRAZR Totally agree! It’s not really old and crap, it’s actually quite amazing how they can do it.
Those suckers were full of lead to protect from x-ray emissions, too.
+RogueRAZR Well, technically it is an electron beam that is being bent, rather than light, but yes, people back then had just as much ingenuity as people today. We've just learned how to do more things over time--we're not any more clever than before.
I have done this in a lab honestly its basic electromagnetism all youre doing is bending an em wave
rbrtck True. The electrons react with phosphor to create the actual light you see.
Woow. This was very interesting and educational. I learnt so much. Thanks
David Morales what the f*** are you talking about?
Hawthorne Okenla maybe you should learnt english
+David Morales what did he spell wrong then
cyber prank I should learnt English? Interesting. You should probably learn yourself before trying to correct. What a dumb f*** you are mate

6:51 I could smell the pixels and the screen. Just like in old TVs we had when I was a kid
That smell of warm lcd and the little bit of heat hitting your face
I feel my hair getting sucked up to the screen
And that startup sound so loud and nostalgic!
wrong timestamp
CRTs don’t have pixels
Slow mo guys: (saying interesting things and discussing information)
Me: “why is that TV *so big though”*
Billy K mines 55". I use a 19" monitor for my ps4.
Because if you are gonna watch a movie/play a game then do it right.
Lmao
because he can
Movie -> TV, game -> monitor.
Thank you so much for the epilepsy warning. I didn’t watch the video :(, but that warning saved me a lot of suffering. Most people don’t think to add such things. You are very considerate. :)
Genuine question, would you not have guessed that a video about tv in slo mo would be a risk?
It didn't flash much i'm sure you'd be fine
JellyMan3634 I don't mean to be rude, but that is an ignorant comment. I don't know much about epilepsy, but I'm sure even a small bit of flashing could set someone off. I would encourage you to think before making comments about medical conditions you know nothing or very little about.
I have photosensitive Epilepsy and I watched the whole video and I am fine, just take your medications and stop being over dramatic
What is epilepsy? What would have happened to you if they didn't give any warning?
My first job was in a CRT TV factory.
This is a review to me, and what a really good video it is.
Remember in the old days when TVs smelled like electrons and were static-y when you touched the screen? Those were the days...
You actually made me nostalgic for screen static, why
Omg same
Lmao I’m 18 and that was like my childhood. And then when you had the tv on you could hear that really high pitched hum. I heard it in this video and it still hurts my ears lol
I used to hear that sound constantly when my school had crts but thankfully we have laptops now to watch am news
you are old
TH-cam thought I might like this video.
TH-cam was right.
Well there's a change
Ik
I mean OK
Ahhhhh every video I'm recommended someone is talking about the recommendation 😭
It happens with me, too.
This video is one of my favorites. I learned a lot and I felt he did a fantastic job explaining
Same!
And this is what we don't learn at school 😂😂😂
@@Yogirlisoncrack Strangely enough i did. Also in a book i read and at college.
This is one of the best videos of TH-cam big thanks to your effort.
It would be interesting to see the arrangement of red, green and blue subpixels on different screens because even different OLEDs use different arrangements.
Yes! I wanted to see the fully lit arrangement on that OLED LG TV. Even when only partially lit, you could see that they are not all the same shape and size like in the LCD. I don't know if this is a PenTile arrangement or not, it would be interesting to watch.
Yes what he said!
Look at 10:54
I was just shocked only just looking how big is your TV in comparison to mine
ANTU SULAKHE i have a 70 inch, idk if he has the same or bigger lol
Yeah, it's a bit bigger than my 32" widescreen Sony FD Trinitron :D
Same
who needs TVs, I just got my Desktop PC, Laptop, Phone, Switch and 3DS xD
Am thinking of getting a couch tho...
Broockle u can't fuck girls on a tv 😂
The screen you are watching this on is tricking you while explaining how its tricking you.
You deserve more credit for that one.

yes and it's called screenception!
5:06 A couple of weeks ago I was watching a Nintendo NES hardware video, and I was amazed how something so old can do specific calculations, switch banks, etc, depending on the specific scan line that's being drawn. It was something like, on scan line 23 switch to this bank to get this sprite, then on line 27, switch back, 35, etc. It's a full world when you slow things down and realize all the activity that's going on.
This video will be shown in classrooms all over the world.
Bushcraft Baxter OOF
Yes. I find this type of video interesting
In some school they don't have tv in classroom though
It even doesn't have any silly antics that teachers would disapprove of.
Bushcraft Baxter until kids start dying of seizures
This gotta be one of the best slow motion videos they've made. It's so freaking cool I wanna die a little.
i need to give this video a like. OH here's one
Uhhhhh alright....
You can watch the video even slower by going to the video setting --> speed --> 0.25 😂

I learned from this video more than the entire CNET channel.
You can learn more from Bill Hammock The EngineerGuy
Omg probably the best video I’ve ever watched. Nice job👍
I dont understand the dislikes... There is nothing to hate on this video. It's really informative and well done
I think (I'm approximately sure) that the guys who dislikes this video are the fans of another company than LG ;)
apparently
+Viorel Christian LG and companies like it have fans...? lmao
Ex GFs ;)
Could be the master race thing...
Super cool video. There's such a wonderful magic to seeing how that all works. Especially 3:03 when it looks as if a retro computer or TV is drawing an image with each digital stroke across the screen 😊🥰
It's actually analog, not digital.
If you think about it, our screen pixels, are generating other pixels from this video.
David McCary pixelception
we need to go deeper.
David McCary i
Our screens generating light, recreating light captured from this video and transfered trough light in fiberoptic cables. light mirroring light trough light.
Ezequiel Telleria that's lit
Whaaaaw! that was utterly fascinating!

This is great, I learned about CRTs long ago and never could get my head around how a single electron stream could light up the entire screen with different colours at "the same time", I now know
mastafixa IKR. It really helped me visualize how the various sections of a tv work together to paint the picture on the front of the CRT.
watched this in my tv production class, and now im hooked to this channel
7:35 that is really cool as a TV repair tech it's awesome to see RGB (red green blue) pixels, i uploaded many tv repairs but never seen a LCD screen under a microscope.
why are u here i keep seeing u on inside edition videos
Tampatec wtf. Your way behind
wut? if a drop of water lands on a 1080p LCD you can see the individual pixels quite clearly
Tampatec Gh
Omg you're everywhere
it is strange to think that the pixels in my pc are recreating some others pixels of a tv

He’s referring to the people who studied this for a year in order to *make* it basic info.
Kyle Rainford I guess he is learning it at college it takes years to learn how TO make it work, not just the info on how it works.
Lol guys. I’m saying this as in I paid a decent amount of thought to this. Sorry for the miscommunication
LOOOOVE the CRT footage. The look of it gives me Tron vibes
science gav and bird-noises gav are two very different people combined into one gav
Omg I hear that high frequency sound when you turn on a CRT TV. Almost forgot that sound.
Proof that my ears are destroyed - I didn't hear anything of that high pitched noise... ^_^
How i knew if my parents had gone to sleep, ring or no ring lmao
LittCoin Af Yep. You could hear that TV buzzing from hundreds of feet away.
Well, I guess we know they have a good mic....
I know it very well. It sounds like my Tinnitus
I feel like CRTs were magic for the time, I seriously wonder how they managed to get this level of accuracy and speed with the technology available at the time, it blows my mind
I totally agree, honestly its really funny that humanity invented 'gun that shoots electrons that are then aimed by magnets at a screen' before 'several tiny lightbulbs that dim and brighten' like one of these seems infinitely more complicated than the other one, how did the electron gun come first??
@@commandrogyne LCDs are liquid crystals that rotate polarised light, controlled electronically with backlit regions. This is much more complex than a CRT. Only now with OLED, are we using the 'several tiny lightbulbs approach. The production of something with so many parts is much harder than shooting electrons at glass.
Wdym with the technology available at the time? Do you think they were some kind of primitives using rocks and sticks to build TVs? Do you think the tech we have today just spawned in? Lmfao
@@AverageAlien i dont think ive ever read anything as stupid as your comment
@@commandrogyne i know right. CRT seems vastly more complicated than LED
This is gold. Pure gold. One of the mysteries from my childhood is finally resolved.
I learned more from this video then an entire day of school
Cookie.MONSTER.EAT.Cookie Cookie.MONSTER Welcome to reality.
... and then one day you realize that ~80% of information taught (at least in elementary / high school) is - if not forgotten just mere months after "learning" - redundant, outdated or incomplete for when you need it, or outright wrong. And that the 20% which is useful could have been learned much quicker and in much more enjoyable way.
School is, I'd argue, mostly just an initiation ritual to servitude.
Cookie.MONSTER.EAT.Cookie Cookie.MONSTER Yess agree man
Let me teach you something else, when comparing something you use *than, not then

Really cool video! Thank you. One of my early memories is from 1975, aged ten, explaining to the rest of my school class how a colour TV worked. I've always found it fascinating, though of course back then it was all CRTs.

julian pizano yeah that's sick how did you find that out is it because you hated your IPhone/IPad and shook it about?
wait this video is 6 years ago?
this looks good quality!
This is amazing!!! I never knew that they were shown in strips! I thought the entire screen was lit up all at the same time! Wow!
Seriously, this is awesome!
And then they are created left to right on top of that! TVs are much more impressive than I had initially thought!

The old TVs were really a marvel of human brilliance. And took it too many years to evolve.
betoen historically talking it evolved very fast, Now days everything os evolving fast
dfo 99 Moores law
betoen you can still see CRT monitors in loads of train stations in Essex (UK)
We still have it and it still runs . A late 80s sony trinitron .
actually, flat screen tv's have existed since 1964. they were more expensive at the time, so didn't become mainstream until the early 2000's when they were affordable. even other technologies were around before the most of us knew about them. like VR for example. they began working on that in the 80s. just because they're back in time, doesn't mean they're not going to be as creative minded, and ponder of such technologies. even before 3d games, they already had 3d graphics with algorithms to apply smoothing to the human facial expressions they were animating. the real genius's in the world, have more stuff going on than what the majority of the outside world knows about.
