To the fact that 1 pixel is smaller than the diameter of my hair. How do they manage to squeeze all that components there. Amazing!!!
ILOVEYIU
The pixels on my screen don't seem to be that small
plus they manage to get the right perfect color rendered and make it appear all in a microsecond amazing
the user lasers and magnifying lens to make etches in metal/silicon chips
@@anim8dideas849 so is the full RGB thing, 1 or 3 pixels?
How the hell did the scientists figure this out in the first place? o.O
Engineers mate, engineers.
Engineers, scientists... eh. I'll just call them technomagicians, because this stuff looks like magic to me, even when fully explained. : p
This is the work of several generations of research and innovation. People constantly learning more about a particular idea, and then creating something novel with that idea.
it is great , it is supposed to be and look like this when we hear it
the question is what can i do , what can you do ? :)
It is 2017 and we have fidget spinners..
Loved this short and precise explaination. It is indeed a miracle of engineering and one that we take for granted. Very well animated and covered. Thank you for the effort.
This is witchcraft, or alien technology, take your pick
It's incredible ! I can't imagine that people made this
Jean Panachay
Yeah I can't imagine how the fuck are signals made/invented
How the fuck do they do it!?
I'm sure aliens teached humans
It is PATRIARCHY.
You don't have to be an alien to use your head
@@spooderdaddy8827 uhm, satelites, and the signals are an amount of vibrations and frequencies you cant feel or see, you cant see vibrations and frequencies in the first place, at least not our eyes
It's actually very simple.
After seeing this I have a new-founded respect for the people that design and invent technology like this. Incredible stuff!
Welcome back InOneLesson!! I still watch your "How Computers Add" and "How a CPU works" every now and then, and I'm currently reading "How do it Know?" and "Code" because of them (I've been alternating between the two and will likely finish both around the same time). Thank you so much and I'd love to see you put out even more as your schedule permits!
there's at least one video on youtube that explains your question (rule #255 of the internet)
Hmmm 255 u say?
Well if u click on 2:14....
Coincidence? I think NOT
I came to find this after getting binary explained to me in another video and computer book. Its... all starting to make sense. I have an even greater appreciation for science the more i study and learn.
This was such an incredibly concise presentation. It fast-tracked my understanding, thank you so much!
Please make more, you are absolutely exceptional at teaching. You make every single aspect easier. You should consider teaching. It would benefit our nation truly
That was a far better explanation than I ever expected. Thank you very much!
Love this channel, happy to see it back! Good video
I've watched a lot of vids about lcd and this one is the best. Good job.
This is easily the best explanation I've found on CZcams.
this channel really is a big help for guys like me that needs clarity
Surely the best LCD video I've yet seen! Awesome work!
You could've added a "extra fact" thing that explains that the 0-255 is just a 8 bit binary number, not an arbitrary value.
*****
That's right.
256(=2^8) is 8 bits for each color, while 16777216(=2^24=256^3) is the total colors that each pixel can have.
That's a lot of information for 1920x1080 screen! You need about 50 million of 0's and 1's for each frame, if it was completely uncompressed.
bunch of geniuses in the chat!
Thank you for posting this great vid. Knowing what lies behind making say, percentage adjustments in photoshop colour, is very helpful.
this channel is brilliant, very simple yet fully detailed explanations. needs alot more content tho. can you please make a video on batteries and sound devices (phones and playback)
Fantastic explanation! Thank you.
Perfect and simple explanation.
you are a legend.
you saved my college assignment after 7 years you put out this video.
Best explanation of how lcd tv works
Excellent Sir,Crisp and easy to understand
Wow it looked so complicated but you made it clear in two and a half minutes. Take my like and this ONE BILLION internetz.
Clear and succinct explanation. Thank you.
Amazing explanation, thank you!
exceptional teaching video.Thanks for your sharing!
enjoying myself here.
Thank you very much for a new teaching and very interesting at the same time video. I hope there won't be so much delay after this one and wish good luck to you and your channel.
The best explanation , thanks !
one of the greatest videos in youtube 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👌👌👌👌👌👌👌👌👌👌👌👌👌
Best video still now on how LCD works 😍
Yayyy a new video.
Thanks a lot, Billy Bob Thornton. Didn't know you were into physics and engineering :)
that was really cool and good ,
I wanted you to know that I feel happy some how ,
because i knew this new info
one of the best videos ever !!!
So cool, thanks.
So it's still a form of scanline? Or is that called rasterization or bitmapping? or bitmapped image.
I've found several videos and articles that describe what this video describes, but I'm having trouble finding one that describes how a particular set of RGB voltage levels gets from the chip that is receiving the data stream to a paticular pixel on the screen. For a 1920 x 1600 pixel screen, that's over 3 million pixels! For each pixel, you have 3 LED's with 2 electrodes each that you have to wire up. So that's 3 million * 3 * 2 = 18 million wires! So I can't imagine that it's actually done with wires? How does it work?
I need you to make 1 video each day :)
Very well explained. Wonderful :)
I thought this channel was dead! Just finished the Braille series a week ago btw
Great explanation! Thanks :)
Thank you - very interesting! I did not know.
My question now is how are wired those liquid crystal units up to the video memory? I can't imagine each pixel is connected with 6 wires. That would be millions of wires to connect. It cannot be a connection in 2D or in 3D.. It must something else....
a great explanation, thank you
Amazing video
Great video, nice explanation.
Great explanation
Excellent explanation
Great video!
Very informative, thank you!
short and perfect !!
explained easily really great
very inforative, will use this for school :)
Great video. Great channel. Just hope it doesn't take as long as this to see another one.
Extremely good video
It's been forever since you uploaded!
I'd appreciate a video about AMOLED screens.
AFAIK it's make up of tiny, "LED-like" light-emitting dots. So it's far simpler than LCD but there wasn't such kind of material in the past and the manufacturing processes for such a small scale, I suppose.
I was playing around with a toy microscope and noticed these rgb bars in the pixels and I assumed it either just switches on or off. I thought the brightness would stay uniform through out depending of the brightness setting. I had no idea even at a fixed brightness the brightness of each pixels' rgb would also play. I cannot begin to understand how they are even made. I mean we always assume oh it's machine, but how? these components are so small. It's fascinating how common this technology has become when you realise how much is going on for something so simple.
Excellent!
Gracias por la Explicacion!
Thanks for the video!
Great great explanation. Would you do one for plasma?
Very well explained
AAAAWESOME!!!
Now i just need to figure out how they manage to send the electrodes into these things seperatly. It's honestly really fascinating ów0
Or aleast it is when you speculate on how you can use this science to create something like an omnitrix or another scienctifical tool of amusement.
So that’s why is see red green and blue when I sneeze on my screen

So much of easy explanation ...thnku so much ...
great video
Amazing
well explained sir, thank you.
Thanks for this. This video explains it a lot better about LCD. Does this apply to IPS and Retina displays as well?
Trinispace A retina display is just a high-density display. IPS I believe has 2 sets of polarizers and liquid crystals for deeper blacks and richer colors
welcome back
so cool. thank you very much!
Thanks for this heping video.
God Bless you
Awesome!!! Thanks
What software is used for this visualization? These 3D models are nice
I love you man thank you
How on earth did anyone figure out that a) there was such a thing as 'liquid crystal' , and b) how the hell did they figure out that adding electrical current would alter the angles of the crystal elements?
Best explanation I could find though and just what I was looking for. Love tech
One thing I don’t get is how you get varying voltage from the binary? Binary is on and off so does each pixel use a digital-to-analogue converter in order to get the different voltages used to vary the brightness or are they just sent through different resistors depending on the binary numbers coming through?…
FINALLY NOW I FOUND IT.
the 1 to 255 make different colors XD
+MAGICOLO Games 0-255 to be exact.
sometimes clever humans have the capacity to do great things ...like design lcd pixels. homo sapiens, i think i love you!
GREAT. The next video should be: How LED monitors works
+Tiberiu Zabara LED monitors are LCD. The LEDs are used for the backlight.
What about plasma displays?
@@SoundWaveTrax I don't think so… aren't LEDs or OLEDs displays in which the individual R, G and B components emit their own light, hence true black/white is achieved?
Or is it that I'm confused between LED and OLED?
excellent and consice! thank you
Shame, this channel has only 150k subs!
Do a video on how OLEDs work (or AMOLEDs for today's technology)!
cool, It's like swallowing pill with knowlede, no tedious and hard learning
thanks a lot very helpful.
This is cool.
Question tho...Who was the individual or individuals who were the FIRST to figure this out?
And how did they figure it out?...what test were ran?...what’s was the first purpose for this technology? Has it always been for smartphones and tv screens?
Thank you, this satisfied my 6 year olds inquisitive mind.
Great 😎😎😎
God bless u, holy shit do u know how many videos were no help! tyty soo much
This has been the connecting point for everything I've researched on pixels
Given that each color filers has 8 bits ( binary digit) of brightness information like this :
1 0 1 0 0 1 0 1
for each bit you get 2 possibilities : 0 or 1
2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 2^8 = 256
is there any reason a horizontal and vertical polarizer are used as opposed to 2 vertical polarizers?
but what's the defrence between the hirizontal and the vertical light
and after the horizontal light pass the first one why it must chnge to vertical
I love how most youtubers say "watching this on your monitor" when most people watch it on their phones or tvs
Doesn't monitor means a computer visual display, aka screen?
How do you control which liquid crystal is being powered?
it's great
i feel bad for pixels while watching a epilepsy video
Even when my screen is completely black, there is still light coming out from it. Where is the light coming from in that instance? Is the light coming through the spaces "between" the pixels? Or is something else happening here?
I the black pixel goes fully dimmed but doesn't turn off. Just guessing.
However, an AMOLED display can actually turn off the black pixel.
When there is light even when your screen is completely black that means there is still some degree of each color between 0 and lets say 20 or less so it's not completely black but it's very very dark that you would think it's black.
Whoever invented LCD must be smoking something good that day.
