Adventures in Science: How LCD Works

2:28 that polarized sunglasses blew my mind

[@shreecharan6224]

Same for me!

[@spechar]

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.

Thats amazing information about Liquid-crystal display: kzbin.info/www/bejne/pYKmYXuOd9Oln9E

[@tomorrowduong4914]

As a mad scientist, I have a compliment! Your video is very well-made successfully covering all the basics! Keep it up!

[@AwesomeasimJunaid]

Tomorrow Dương can I pls know where can I find further information on this topic ?

[@Ash-ec4ip]

literally watched soo many videos but wasn't able to understand this but THIS VIDEO MADE THE CONCEPT CRYSTAL CLEAR....THANK YOU SO MUCH

[@TeagueChrystie]

Dude, this is *fantastic.* Thanks for making it.

[@richardbohunovsky2404]

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.

[@ANTONIONICOARA]

If there were all the professors like you, students will be passionate about learning Very well-made video, congrats!

Finally a good video that doesn't feel like an ad for some SparkFun product! Keep it up!

[@aolien2739]

I couldn't make enough sense out of all this just reading about it, but you made it a whole lot easier! Thank you!

I've been looking for an explanation and saw many videos, this is the only one that I understood!

[@Inspired-robots]

finally my doubts are clear on lcd by watching this video. All explanations are very good

[@huuchinhnguyen5808]

The best explanation what ever I’ve watched, thank you so much

[@anastasiamurawski6179]

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.

[@anastasiamurawski6179]

Sorry for getting political on ya.

[@miltonm1215]

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!

[@jwd.t]

Oh great !!! A very clear video to understand TN panel LCDs. Can you please make one tutorial on IPS type LCD panels ???

[@Tattlebot]

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.

[@Liravin]

can you do a video where you disassemble an LCD so one can see how the source relates to the individual pixels?

[@IshmaelAtadika]

You are a very good teacher, your explaination superb,thanks.

[@drHatim-bt1eu]

Great explanation and experience. Thank you for sharing.

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.

[@Tattlebot]

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.

[@YFTOUCH]

Fantastic!Big compliment!

[@he.lena21]

[@sooryanarayanan4273]

[@KeithMakank3]

My favorite property of liquid crystal displays is how it makes extra pairs of hands show up in the demonstration :P

[@ash6951]

great video ! Thank you so much

[@SevenDeMagnus]

They still work as rasterization? Like scanlines? What is a bitmap monitor?

[@arrenroughe517]

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

[@spkrman15]

Love the videos.

[@ShawnHymel]

Thanks! Glad you're enjoying them :)

[@ejmtv3]

Im glad LED display is born. Much easier to understand than LCD's

[@DerMarkus1982]

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! 😊👍

[@candycommander]

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?

[@loganishere4760]

[@davideiotti9725]

Extremely useful!

[@shavais33]

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?

[@rushabhshah7187]

if applying voltage doesn't pass light through second filter...then why we have VDD supply in LCD???

[@sonarbhagyashri1809]

Awesome explanation 👍

[@AbdullahAlMamun-ou3qg]

Nice explanation !

[@haleemahahmad1088]

but what happens during a video? How does the light move to create videos?

I saw your cardboard demo I clicked like ;)

[@christinzing9305]

I wish I could meet u once.. U r just awesome.

[@sajithsadakalum471]

wow great video. thank you

[@leif1075]

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??

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?

[@asadalikhan7389]

Whatva great expalination

[@Klesx]

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

[@kennethj8236]

Come on CompTIA, why didn't you just say that! This makes a LOT more sense! hahahaha!

[@W0954]

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

Alphabet! Your algorithms are so bad at predicting what I want! He said a line from Dr. Demento! I want that!

[@BetaCuckAlpha]

I was with you until you said upgrade from Cathode Ray Tube

[@Tattlebot]

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.
