The orderly beauty of liquid crystals

[@batzlat1]

I've watched dozens of videos on how LCD displays work. Only now, after watching this video, did I really understand it! Great video, thanks!

[@Tehn00bA]

5:40 that finally explains why dark mode/black screens consume more energy than white screens in LCD (while its the opposite on led). I knew that LCD used more energy when displaying black because my gameboy battery light would turn red everytime a black screen appeared, but never knew why. Great video!

[@ZeranZeran]

Wait.. I keep all my backgrounds as just pure black because I thought it was better for energy consumption, wow. Thank you!

[@TheWeirdPianist]

@@ZeranZeran That mostly works on OLEDs because they're self-emissive. There is always light shining behind LCDs so what they show doesn't matter too much. Most show black by default, so to show white they need to use energy. But some LCDs show white by default, so they consume energy showing black. The LED backlight behind the LCD is the one consuming the most power, so you can just lower the brightness if you're worried about it. If you have an OLED screen, black backgrounds will also have a noticeable effect. The person above is talking about a very specific LCD screen that didn't use a backlight. The greenish ones you find in calculators. They use energy to display black. But I don't see why they would consume more of it.

This video is absolutely incredible. That was so informative and well presented!

[@plumnuts]

absolutely incredible how much i learned from this low-key video. everybody should see this. i'm talking core curriculum.

[@baldpipesmoker1]

It's amazing what can be done with liquid crystals. An LCD screen is more complicated than I thought. Thank you for explaining!

[@kateyelkovan]

this video is so cool

[@chandankunal]

Awesome work! Super well explained. I always look forward to your videos!

[@lelsewherelelsewhere9435]

Really great video!! Going to use this as my go to when explaining to others.

[@newgoogleaccount3526]

Came from LTT, great explanation in one video.

[@omsingharjit]

It feels Awesome watching your presentation

[@gegedepardi3486]

C'est une approche très théorique et universitaire des cristaux liquides, un petit show des différentes interfaces des années 60, utilisant les cristaux liquides aurais apporté une petite approche ingénieur au sujet. Surtout que niveau ingé lcd avant le pixel c'est très "cru" très visuel comme technologie. C'est plus simple que nos lcd d'aujourd'hui on peu les décortiquer et apprendre comment l'ingénieur à adapter les cristaux liquides sans notre tendance à miniaturiser. Je critique parceque la vidéo est quasiment parfaite c'est incroyable. Trop trop fort la qualité, la maîtrise du sujet, tout est carré. C'est vraiment de la vidéo de qualité félicitations !

[@davidzamora4654]

Amazing video. I would like to watch another video on different liquid crystals or even taking a little depper understanding of the ones you showed us.

[@salmagamal5676]

Very very well explained thank you!

[@FabienCharles108]

Fantastic video!!!

[@samuelcarvalho3691]

Outstanding Video. This video ought to have more views and this channel ought to have more subscribers!

[@leonardodeangelis4403]

You deserve more subscribers

[@parimisreekar]

Lucid and accessible presentation. Helped with introduction to LC polymers.

[@geckolantern]

This video is incredibly clear and concise. Thank you!

[@jagroopkaur9877]

Well explained and presented👍

[@thirandieamaratunga7278]

Wonderful work! Helps understand a complex concept in a simple, intriguing way.

[@waleolapo]

Thank you for the thorough explanation

[@cristianconstantin6496]

Great video, you explained the concepts very well and the animations were right on point. I have to point out a mistake at 1:54 - the Bend configuration is the one on the left and the Splay configuration is the one on the right, as per Peter Colling's book Liquid Crystals (Edit: I was wrong because of misinterpretation)

[@TheLutetiumProject]

Thanks! But we stand by what we put in the video... Splay is a simple divergence, like on the schematic on the left.

[@cristianconstantin6496]

my apologies, I misinterpreted your bend image and you are definitely correct. It all comes down to how the orientation of the director changes with position

[@NagawaRashidah]

Good en well explained thanks

[@tejaswibhagavatham4226]

Crystal clear explanation thank you for making this video 🤝

[@Samanimeeditor]

Wow amazing video 👍👍👍😀😀😀

[@AntiheroYouth]

4:55 Not sure implying I’m going to disappear or my defects will disappear. Both are true, I guess.

[@kelvianmularso2587]

Cant agree no more, really easy to understand, thanks

[@I_am_Rathore]

Amazing video and presentation...Thumbs-Up

[@racheledominguez308]

Great video!

[@thenoodlesaresoggy3728]

thank you, thank you so much! I've had trouble understanding what's up with liquid crystals. Thankfully, I found this! Saved me from a lot of probable breakdowns.

[@konradkow]

We are the liquid crystal being vibrating with energy 💦💎🧘 And I am starting to understand how this is being naturally and artificially influenced in us. Thank you for the lesson. ✌️😊💛

[@JizzontheToilet]

this is really intesteresting. You presented it really well, probably would have taken 3 college classes to grasp what you did in 8 minutes.

[@kchemistry1268]

So nice information

[@khareldn]

It really helped a lot! Thank you.

[@virtuallysarvad]

Such a good explanation. Sad that you'll stopped uploading :(

[@almominrafi5505]

well concept sis

[@upisewingbyupeksha675]

Thank you for that explain 💝

[@IshvaraIsOne]

Top video!!!

[@Kram1032]

Lovely video, very interesting! Simply explained and informative. Could you, for the future, try leaving more time between upload and premiere? 'cause it feels a little silly to watch the premiere in 360p when you could come back a couple hours later and it'd be HD :)

[@TheLutetiumProject]

Thanks for the feedback! The video had been uploaded for weeks in HD. We're all really puzzled that KZbin decided to cap the resolution during the premiere at 360p. We have no idea why! Have you watched other premieres on the channel by any chance? If so, did you witness the same issue for other videos?

[@Kram1032]

@@TheLutetiumProject ok that sucks. Really weird. Don't think I caught one before

[@Elias-Liv]

i just watched it at 1080p

[@Skylerfi]

Maybe it's worth talking about different types of liquid crystals? Say ionic liquid crystals, etc etc

[@itzanonmoose8328]

Good stuff.

[@yaghiziad1034]

How do we get 256 different shades of color on a subpixel ? Does the liquid crystal change the intensity of the light that passes through aswell ?

[@charwyrm8702]

Comment for the algorithm, really good stuff guys!

[@Hammelkottlett]

Now I understand! Fantastically explained! But where did you get that brezel? :D

[@ThouBeteraNay]

"If we give them enough time, the defects will disappear - just like you." Ouch. That hurts.

[@AddisonJamesHoward]

what could cause this type of effect to show up on film monitor?

[@ehsanayar7859]

Excellent

[@jiachiye1226]

3:39 : I dont'd understand, sees like the polarization of the incident beam didn't change at this direction. Why "completely different"?

[@davidzamora4654]

I have the same question. I don't know if it has to be with, let's say, a quantitative value for the interaction of the light with the molecule. It's not the same when is travelling parallel to the longest direction, than when it's perpendicular.

[@Movieclip.s589]

I was going to buy a monitor and now I'm here.
