This was one of the coolest video I've seen. Especially the visualizations of the polarization of light was so clearly explained and visualized! I've taken courses in EM waves and never have I managed to get the full understanding of what polarized light is or what a polarizer does. Thx !
I am addicted to your video sir. I am b.sc mathematics honors student and I am interested in technology video. Due to financial problem I was not able to do engineering but your video fulfill my dream. I hope I will get such video in future in this way. Thank you
The same story.... Wanted to do physics and engineering but couldn't due to financial problems, went for BSc mathematics.. Then PG in English Literature though I am an assistant professor of English with a good income but I'm not satisfied... Don't go the way I went
There are so many videos regarding the LED/LCD displays but none can beat this video. With accurate and crystal clear information and amazing animations. Thanks Lesics team.
Man I can't appreciate this channel enough! It is so so so damn educational, great quality animation and explanation. Basically a hub for all the engineering nerds!
Yep. Its fun trying to tell people that your new led display is actually a lcd display with a different light source compared to older lcd display with florescent backlight. Unless its OLED or micro-led (if they decided to use micro led directly as the pixel source and not as a backlight for an lcd display), its all lcd.
Soft of. Each individual gets its own independent brightness level, instead of having a solid backlight for the entire screen. You get better contrast and color accuracy, but typically at a much higher cost than traditional LCD technology.
This is not a video about LED's but a video about LCD's (with white LED backlight) explaining how LCD's work. This should have been called "LCD Display | The detailed Physics behind it".
I watched some videos in the past on how led display works but I still didn’t fully understand regarding liquid crystals. This one did it for me, thanks 👍.
This wasn't really a video on how LED displays work (which are referred to as microLED displays) but how LCD displays work (who's only relation to LED's is the use of white LED's for the backlighting).
The thought, theory and technology behind this is insane. Go from inventing the light bulb to filtering led light through lcd using changes in polarity… 🤯
Honestly what I would be more curious about is how these tiny elemts are produced and how the signal gets to each pixel. Nontheless a great video of showing how the pixels themselves work
@@joseville yeah but like, how does it work? Like, according to this video, it would seem that just for a single pixel you'd have to manage hundreds of different inputs. It surprises me that TVs don't just glitch out randomly. We don't really think of our TVs having the same calculation power as our computers. We just see them as another appliance. But it really feels like you'd need a super computer to run all the calculations just for the display alone.
As a developer, I knew about the process by which colours are produced digitally. But didn't know about the inner working. Amazing work by the engineers!
Great video ✌🏼 Small detail: when unpolarised light goes through a vertical filter, I think only the horizontal component will be transmitted (not the vertical) 😃
Yeah, probably a nomenclature mistake: if only the vertical component is passing, then it's because it's filtering the horizontal component; therefore it's a "horizontal filter"... but because the slits of the "horizontal filter" are actually vertically oriented, it's easy to call it a "vertical filter" because it looks vertically oriented. This stuff was easy to get confused with when studying the properties of light in high-school physics way back in my time, and I guess it still continues...
It was very useful as always, I would like to see a video on Graphene batteries - functioning , structure , capacity & features, obstacles etc. Kind of you.
Thanks for taking efforts to explain how it works, I have been struggling to find such explanation on yt for a while. One small remark: Though micro LEDs are interesting tech, the qdel looks even more promising (due to theoretical low production cost based on its simplicity).
OLED is by far the best display I've seen and used. by using samsung s20+ now, if I went back to using vivo y20 which has lcd 720p panel, it clearly visualize the difference between oled and lcd. The blacks are 99% black and you really can't see blacks in dark room. Colour accuracy is correct for most of daily workflow. Professional editors also use oled laptops and monitor to fullfill their accuracy demand.
Very very important thing. Thank you so much sir. Please make a video about the working principle of computer hardware like processor, RAM, Hard Disk and SSD in details video their behind of the physics.
this i an excellent video, and ive seen alot, about screen technologies. the only other one id say compares is steve moulds explination of sugar waters dextro effect on polarized light caused by the charlity of the molecules
The polarization using 3 magentic field that can change with each timers separately and superimpose create light color in motion of time and tine resolution is the pixel as small as plank size
Skip the waitlist and invest in blue-chip art for the very first time by signing up for Masterworks: masterworks.art/lesics
Sir, next time make vedio about petrol pump machine how they work
WOW man did you lose a bet? Crazy how challenging this must have been. This production is amazing. You should receive a prize for this.
Can I request a video on Heating and Cooling?
epic engineering indeed

And people with money are taking admissions in engineering without the love or passion for it and ruining it for all

So, most of the marketed "LED Displays" are LCD display with LED backlight
Yep.

Soft of. Each individual gets its own independent brightness level, instead of having a solid backlight for the entire screen.
You get better contrast and color accuracy, but typically at a much higher cost than traditional LCD technology.
And if the polarization filter could really block all the light we could achieve true blacks like with an OLED
Dam right! 💯
Yes, correct would be to also call them that. LCD with QLED backlight.
Thanks
Thanks!
Thanks
Thanks!
This is not a video about LED's but a video about LCD's (with white LED backlight) explaining how LCD's work. This should have been called "LCD Display | The detailed Physics behind it".
LED TVs are lcds with led light background
yeah lmaooo
I watched some videos in the past on how led display works but I still didn’t fully understand regarding liquid crystals. This one did it for me, thanks 👍.

One of the best and coolest explanation I have ever seen!
The best video explanation about LED monitors i have seen so far. Thank you!
Been watching this channel on RUclips for 2 years now and I have learnt so much. You guys do amazing work! Hope I can fix something someday.
Finally found someone who can explain in detail how LCD/LED works
This is the best animation I've ever seen explaining liquid crystal. Thanks really
Hi...... I love your videos soooo much.....
They are awesome and very clear to understand
The thought, theory and technology behind this is insane. Go from inventing the light bulb to filtering led light through lcd using changes in polarity… 🤯
Thank you so much for this video. It helped me so much to understand the tech behind LED!!!! Thank you again!!!
I knew it already. ..but not so detailed, very well explained 👏
Very good explanation. Thank you. Keep posting more explanations.
Wait lesics got a sponsor
Nice one congratulations
really amazing video
Your video is very proffesional.Useful!
thanks. This channel made it easy to understand how its work
Best explanation! Thank you so much.
Love your explanation and efforts ❤
Explanation is next level with Animation ❤️. Thank you for sharing.
This is one of the best explanation I have seen. I wish I could understand how to get lower values of the rotation.
Fantastic explanation. Magic explained.
Honestly what I would be more curious about is how these tiny elemts are produced and how the signal gets to each pixel. Nontheless a great video of showing how the pixels themselves work
Right!??? Like how do these individual ARS’s know how or when to rotate the light source to make the image that is required !?
processors are manufactured using microlithography so I would imagine some of these elements are manufacture using a similar process.

Thanks for vid. Little correction: 2:47 - the right direction of e/m wave propagation is opposite.
As a developer, I knew about the process by which colours are produced digitally. But didn't know about the inner working. Amazing work by the engineers!
this channel is amazing, thank you very much
Video request/suggestion- How does a CCD camera works. Or how does colour cameras work. History, basics , applications.
Great video ✌🏼

What does make them to have differential speed!
good to see you💌
interesting video...❤❤👍
Dude, your video is awesome. Good work ...
Thanking you till next time...
Wow.
What a great knowledge you offer.
Thank you, bro.
Please make video on additive manufacturing technology
This Thumbnail is better than last one, good work guys
Only put a drop of water on phone display(with white background) then pixel will be visible.✌️
Thanks for the second trick
Best video to understand
Lesics provide good quality information about science 👍
This is my first time coming across this channel. This is odd since it has 6.5M subs!
Pls make vedio on lcd working principle
Very Nice Bro! Get Good People!
Very useful vid. Please deep dive also in twisted nematic, inplane switching and vertical aligned LCD techniques to visualise their pros and cons.
Thanks for your effort in making this video which contains a lot of informations.
This is great!
Every time i watch your amazing video's i understands that everything is much complicated then what i thought.
Nice info, thanks for sharing it :)
1:20 - there are colours unavailable in the (positive) RGB space. I mean wavelengths which stimulate cones in a way no RGB combination does.
That's awesome can you guys make a video on how micro led works?
Thanks you for your great work.
Sir, please make a video on working of computer.🙏🙏
magic floating screwdriver @ 0:32
pleas can make a video about old processor and a new tech of processor
Top class edit 🔥
1:15 cool! Is this how smart color changing light bulbs work?
my head explodes when i watch these videos
The polarization using 3 magentic field that can change with each timers separately and superimpose create light color in motion of time and tine resolution is the pixel as small as plank size
wow, complex things turn into simple
great job sir..you make awesome videos with complete detailing..❤️ from IITK🔥
Samsung is really a leader in Display technology. Their QLED, AMOLED and QD-OLED are great.
Can Lesics make a video on how the differential lock works?
I still don’t get how engineers figured it out in the first place.
Make video's on how to made Microprocessor and how to work
8:54 There are now LED monitors with variable backlight.
Wow amazing , nice Vidio thank you for your sharing 👍👍🙏
thank you so much
broooohh .....big fan .....
Please describe about electronics control panels..
Great work 🥳🥳🥳 Thanks 💜💜💜
