You want mind blowing, try putting on polarized sunglasses while watching LCD display and tilt your head 90 degrees. This is why pilots don't (usually) use polarized sunglassed. The displays in the cockpit are LCD's and the sunglasses may sometimes hinder their ability to see them.
I used to work for a company that made LCD's and it was the best job I ever had, because I am a nerd and found fun and interesting. Unfortunately the place went under or rather over seas (the plant closed and was moved to Japan) , a lot of people lost their jobs, What a shame. But people don't want to spend big bucks for products with LCD 's , we 'Mericans want to go to Walmart and and buy a super sized TV for cheap . We weren't that advanced, we only made small glass displays for things like gas station pumps , but still it very interesting to learn the science behind how they work. Thanks for the video. I'm an artist and I've always thought about how LCD's might be used to make some kind of art. It's working with color and light, which nerdy artists like me just love to play with.
Very well said lol indeed it is like working with art. Im about to start an internship at this LCD company and im very excited to learn and adapt to everything that comes within the job!
Omg thank you so much, you explain this topic so well, so far I have only found complicated explanations about TN LCDs, but your video is easy to understand and makes important points! Thank you.
Note that your mockup of the TN voltage on state is incorrect. The LC directors orient toward the electrodes, breaking the twist. What you depicted was a sort of in-plane switch. TN LC is positive dielectric anisotropic, so you would have to move the ends of the LC toward the polarizer, sort of like a fallen stack of books.
Awesome display of light's polarization! (display? See what i did there? 😁) No, really. I've never seen such a graspable demonstration of that phenomenon! Keep up the work, SparkFun! 😊👍
OH my goodness, the tasty info was so informative i had a braingasim, thanks a bunch for this, I am now subscribed. im genuinely always happy to learn new stuff that i had no idea about, you you hit that spot just right, lmao.
There's a 60 year old film that described how analog television worked. (It was new at the time.) This is close to describing how the digital TV of today works but isn't kid oriented. Has anyone done *that* yet?
why are we using a liquid crystal layer any way if the aim is to get the stop the inverted wavelength by the front polorizer , could we just use 2 different polorizer and block do the same
I was wondering how LCD works and made a guess before watching, then watched. My guess was that the light shone on the crystals basically on the side that would produce the colour needed from red,green,blue. I was wrong, but the concept was close lok
How does a signal representing a particular pixel value that is addressed to a particular pixel makes its way from the chip that is receiving the video signal all the way out to the individual pixel? When there are millions of pixels? There can't possibly be millions of individual wires?
But if when you apply voltage light doesn't pass through, then hkw is an image produced on the screen....that doesnt make sense..unkess there is a ckunterscting voltage but steady current..anyone else wondering??
And how each pixel is programmed ? What kind of computer code/language is used ? How it's all coded in radio waves and decoded to digital and translated ? How it's builded in a factory ? Where the liquid crystal are extracted ? So many questions.... I might start to have a panic attack by not accepting my extremely finite form of life incapaple of learning everything that I want ....LOL
I get it, but in lit offices, working on bright imagery like word documents, CRT can reach barely above newspaper perceptual contrast, about 20:1. LCD retains very high contrast, so colour saturation is much more stable across ambient light levels, at the cost of poor saturation of very dark shades. A good IPS panel will have even better viewing angles than CRT, due to lack of thick reinforcing glass. Then there is also energy savings in producing and using LCD.

Thats amazing information about Liquid-crystal display: ua-cam.com/video/oQC0HXBnrio/v-deo.html
As a mad scientist, I have a compliment! Your video is very well-made successfully covering all the basics! Keep it up!
Tomorrow Dương can I pls know where can I find further information on this topic ?
Friedrich Reinitzer was my great Uncle!
LCD tech is so deep in itself

@@miltonm1215 Thanks and good luck to you!
literally watched soo many videos but wasn't able to understand this but THIS VIDEO MADE THE CONCEPT CRYSTAL CLEAR....THANK YOU SO MUCH
Dude, this is *fantastic.* Thanks for making it.
You just explained to me in 9 minutes what my textbook didn't for the last year!
True.. 😄
If there were all the professors like you, students will be passionate about learning
Very well-made video, congrats!
finally my doubts are clear on lcd by watching this video. All explanations are very good
Great explanation and cardboard physics demo!
can you do a video where you disassemble an LCD so one can see how the source relates to the individual pixels?

Thanks for the extra explanainstion sparkfun
Finally a good video that doesn't feel like an ad for some SparkFun product! Keep it up!
Wow. When you turned that glasses 90 degreee, i was like "wow"
Great video, very simple and professional, keep up the good work.
I couldn't make enough sense out of all this just reading about it, but you made it a whole lot easier! Thank you!
The best explanation what ever I’ve watched, thank you so much
I've been looking for an explanation and saw many videos, this is the only one that I understood!
Oh great !!! A very clear video to understand TN panel LCDs. Can you please make one tutorial on IPS type LCD panels ???
Great video dude. Honestly the best Lcd vid on the Tube.
Im glad LED display is born. Much easier to understand than LCD's
Great explanation and experience. Thank you for sharing.
You are a very good teacher, your explaination superb,thanks.
I cannot believe how easy you made it to understand
the best explanation for LCD 👍👍👍
What a great explanation. Keep up the good work.
Excellent video. Great presentation too.
Fantastic!Big compliment!
beautiful video, thanks
My favorite property of liquid crystal displays is how it makes extra pairs of hands show up in the demonstration :P
Amazing video, thank you so much!!!
Great video!! it's much easier to understand ❤ thx so much
omg Best video i have sceen on how LCDs work thank you so much !!
Awesome video!
Great explanation. Thanks.
this video was so helpful, thank you so much!!
Wonderful work
Thanks
Awesome explanation 👍
Quite effective explanation. Thank
Nice explanation !
Love the videos.
Thanks! Glad you're enjoying them :)
Extremely useful!
Thank you so much!
Very good
Great video
This is the best content which i had ever seen related to this topic 💖... Thanks a lot...Well explained...😎
wow great video. thank you
What's the point in having the second polarized filter if you can just remove it and have the same light luminate the panel image?
I wish I could meet u once.. U r just awesome.
I just LOVE "advetnures"!
Lol...thanks for catching that. All fixed now.
Keep up the good work my friends!
@@ShawnHymel Do you still upload video on this channel or make video for this channel (I'm not sure. Sorry.)
@@tahsinuzzamanemon7238 I do not. I have my own channel now with a few videos and links to some others that I've done.
The cellular phone is a 3D gadget even the LCD display is a 3D material since the display has many electronic layers in order to be functional.
Awesome display of light's polarization! (display? See what i did there? 😁) No, really. I've never seen such a graspable demonstration of that phenomenon! Keep up the work, SparkFun! 😊👍

They still work as rasterization? Like scanlines? What is a bitmap monitor?
This is just great, thanks.

Note that virtually any LCD you use does not use twisted nematic. It is likely to be In-Plane Switching, which was made by Hitachi in 1988.
There's a 60 year old film that described how analog television worked. (It was new at the time.)
This is close to describing how the digital TV of today works but isn't kid oriented.

I saw your cardboard demo I clicked like ;)
So to produce black colors you are basically producing more electricity.. Thus affecting battery life
I was wondering how LCD works and made a guess before watching, then watched.
My guess was that the light shone on the crystals basically on the side that would produce the colour needed from red,green,blue.
I was wrong, but the concept was close lok
I understand it so much
A very nice video

Whatva great expalination
I'm watching this on a TN panel
Nice one
Joke's on you, I'm watching on a CRT.
Trinitron ftw ;)
Thank you !
what's the difference between E-Ink and LCD no backlight needed screens?
*_Love The Bloopers!_*
Nice
if applying voltage doesn't pass light through second filter...then why we have VDD supply in LCD???
but what happens during a video? How does the light move to create videos?
good ! i will be think.
Thanks bro
haha carrot goes brrrrrrrr
But if when you apply voltage light doesn't pass through, then hkw is an image produced on the screen....that doesnt make sense..unkess there is a ckunterscting voltage but steady current..anyone else wondering??
Enjoyable
thnx
Holy shit this video was so educationAl
I bhoucht a m3 band its lcd display pixel are not working
explaining lcd displays but at 8:00 shows sn oled phone
hold on doesn't the s5 use an amoled
Come on CompTIA, why didn't you just say that! This makes a LOT more sense! hahahaha!
This is crazy
lol remember indaglow watchs? im sure i spelled that wrong... how did they work?
And how each pixel is programmed ? What kind of computer code/language is used ? How it's all coded in radio waves and decoded to digital and translated ? How it's builded in a factory ? Where the liquid crystal are extracted ? So many questions....

But what is the liquid crystal made of???? I’m sure it’s not carrot juice! Why doesn’t anyone explain this?
Still have not found that out lol
