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?
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.
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.
After seeing this I have a new-founded respect for the people that design and invent technology like this. Incredible stuff!
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..
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.
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
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
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!
This was such an incredibly concise presentation. It fast-tracked my understanding, thank you so much!
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!
That was a far better explanation than I ever expected. Thank you very much!
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'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.
So that’s why is see red green and blue when I sneeze on my screen

This is easily the best explanation I've found on RUclips.
Love this channel, happy to see it back! Good video
this channel really is a big help for guys like me that needs clarity
you are a legend.
you saved my college assignment after 7 years you put out this video.
Excellent Sir,Crisp and easy to understand
Perfect and simple explanation.
Fantastic explanation! Thank you.
exceptional teaching video.Thanks for your sharing!
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....
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?
I've watched a lot of vids about lcd and this one is the best. Good job.
sometimes clever humans have the capacity to do great things ...like design lcd pixels. homo sapiens, i think i love you!
It’s a combination of technologies. Edwin Land invented the Polarizer in an inexpensive way.
Wow it looked so complicated but you made it clear in two and a half minutes. Take my like and this ONE BILLION internetz.
Best explanation of how lcd tv works
I need you to make 1 video each day :)
Thank you for posting this great vid. Knowing what lies behind making say, percentage adjustments in photoshop colour, is very helpful.
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.
i feel bad for pixels while watching a epilepsy video
one of the greatest videos in youtube 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👌👌👌👌👌👌👌👌👌👌👌👌👌
Whoever invented LCD must be smoking something good that day.
Thanks a lot, Billy Bob Thornton. Didn't know you were into physics and engineering :)
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
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
FINALLY NOW I FOUND IT.
the 1 to 255 make different colors XD
+MAGICOLO Games 0-255 to be exact.
I got my eye very close to a computer and i saw the colours on the pixels (they were REALLY small). For some reason I saw red, yellow and black
Yayyy a new video.
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.
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)
Best video still now on how LCD works 😍
is there any reason a horizontal and vertical polarizer are used as opposed to 2 vertical polarizers?
But how does the monitor send a signal to each pixel? does that mean each pixel is wired? I thought thats why mini led is hard to make,
Found the answer from reddit, doesn't explain why the mini led is hard to make, and what kind of tiny wires are they using?:
"ACTUAL ANSWER: most screens are subdivided into squares or columns of pixels. The actual pixels are made up of 3 subpixels. Yes, each subpixel has two wires going to it, usually one wire above going up and down and another line under the going sideways, like a grid with subpixels located at the intersections. Inside the screen there are "column driver" chips that take binary address along with color and intensity and convert it to a signal to drive the subpixels. If your monitor is say 1920x1080, you can have twenty 192x540 blocks each driven by their own driver. All these chips are then connected to the master chip that takes input from your videocard, does address conversion from x,y,intensity to column,x,y,intensity. This master chip has very few data lines coming from the videocard."
Shame, this channel has only 150k subs!
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?…
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?
that was really cool and good ,
I wanted you to know that I feel happy some how ,
because i knew this new info
This video made me appreciate the price of my TV..
I knew that, but I was hoping to see how every crystal connected?! Even thin copper wire will block big area, I think they connected as touch screen every row by one line vs every column... But how
It's been forever since you uploaded!
Excellent explanation
Clear and succinct explanation. Thank you.
Great explanation
I thought this channel was dead! Just finished the Braille series a week ago btw
cool, It's like swallowing pill with knowlede, no tedious and hard learning
Pls also explain about optical and megnatic memories
How the f is it possible to make pixels so small. I’m currently looking at my phone screen and it’s just so unreal how small those pixels are.
My question is that if the smallest iPhone has a little less than 2,527,200 pixels, how the heck do they fit all those wires in there?
I can't believe that there's so much info in just 2minutes 38seconds
Gracias por la Explicacion!
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.
So basically, light comes on, based on current, so much light comes through an LCD electrode that then hits an rgb filter?
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.
Ever wondered why when you touch your phone screen gets wet you can sometimes see RGB

The best explanation , thanks !
Why do we need to stop twisting when we light was already horizontal ?
+Alex John In short, we need to stop twisting in order to make the light pass horizontal (and not twist to vertical), such that it is blocked and produces darker shades up to black.
According to the video ( 1:34 ), the light gets twisted by default when no electricity is applied to the electrodes, and the liquid crystals are in their normal, twisted arrangements. Therefore, the horizontal polarized light (from the first polarizer filter) gets twisted to the vertical plane, passes through the second polarizer filter (the vertical one), resulting in a lighted sub-pixel (one LC with the the color filter at the end).
When the electricity is applied to the electrodes, the liquid crystals lose their twisted or "normal" arrangements and are all arranged horizontally, simply passing the incoming horizontal light forward, which then gets blocked by the vertical polarizer filter, resulting in a black pixel or color filter.
*+Instrumental Corner* Why not just say it's window science? It's like window blinds.
enjoying myself here.
Amazing explanation, thank you!
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?
Very well explained
Amazing video
welcome back
a great explanation, thank you
Can you do how to create awesome videos and intros for you tube?
This explanation is very well done but your transcript for this video is incomplete (FYI)
its a 9 year old video. nobody will care about the transcript.
Fuck that 1 dislike.This video is aaaammmmmmmaaaaaaaaaazzzzzziiiiiiiiiinnnnnnnnggggg !
I didn't see this in an lcd I saw this on a Crt
*Why does a “dead pixel” turn black?*
Great video. Great channel. Just hope it doesn't take as long as this to see another one.
one of the best videos ever !!!
Great video, nice explanation.
are you still there? kinda miss you In One Lesson
How is the electricity that passes through the crystals controlled?
Amazing, they have managed this so small, this made me think that the technology out there in the market are just suppressed versions on the real technology scientists have, they may have now the most powerful technology we never thought of..
Amazing explanations thanks
So much of easy explanation ...thnku so much ...
Very well explained. Wonderful :)
I tought that title says how to see pixel and how they work
Question: My display has over 8 million pixels, so each need 2 wires to connect, so that 16 million wires that need to be addressed by the display driver.... I don't see 8 million tiny wires anywhere, or even 10 thousand, or even 1000 of them... how do they activate a single pixel exactly when there are no direct individual electrical connections to it?
explained easily really great
Great explanation! Thanks :)
great video
watching this while trying to figure out how to pop a pimple
But I have another thing I am curious about. Why put up a horizontal polariser if you need to make the light vertical? Why not just put vertical polarisers right in front of the backlight? Why would you go through all of this LC stuff if you could just put up a vertical polariser at the start?
the idea is to switch between a bright state and a dark state.
when the liquid crystal is subjected to an electrical field, it looses its twist angle, therefore losing its ability to twist the polarization of light.
so you exploit crossed polarizers, between crossed polarizers all light is blocked unless you have some kind of material in between that can switch the polarization of light.
Excellent!
Very informative, thank you!
