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 !
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.
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.
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
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!
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).
@@DrR1pperled is same as lcd , but uses led as back light source, The one you are talking about is called mini led technology . Its different than led/lcd s. Led displays are not called micro leds .. Led and micro leds are two different technologies.. get you knowledge correct. When you go and buy led tv from market ,, and open it you will see the same technology… Microled is different, samsung calls it , nano cell technology.
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… 🤯
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!
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.
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.
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.
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).
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
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.
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...
The polarizer porarizes light perpendicular to the chain of molecules/ the metal strings. What i mean is that the transmition axis for the polarizer isn't like you made it look like, it iz perpendicular
To achieve perfect blacks, new TVs and monitors use multiple dimming zones which basically means using multiple small white backlights instead of a big one as the primary source.

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

So, most of the marketed "LED Displays" are LCD display with LED backlight
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.
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.
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.
I am addicted to your video sir.
I am b.sc mathematics honors student and I am interested in technology video.

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

LED TVs are lcds with led light background
yeah lmaooo
This is led ,
The only difference been led and lcd is the back pannel lighting source, everything else is same .
Thanks

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.
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!
This is the best animation I've ever seen explaining liquid crystal. Thanks really
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… 🤯
Finally found someone who can explain in detail how LCD/LED works
Wait lesics got a sponsor
Nice one congratulations

Thank you so much for this video. It helped me so much to understand the tech behind LED!!!! Thank you again!!!
This is one of the best explanation I have seen. I wish I could understand how to get lower values of the rotation.
Thanks for vid. Little correction: 2:47 - the right direction of e/m wave propagation is opposite.
Hi...... I love your videos soooo much.....
They are awesome and very clear to understand
Explanation is next level with Animation ❤️. Thank you for sharing.
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.

Video request/suggestion- How does a CCD camera works. Or how does colour cameras work. History, basics , applications.
really amazing video
Very good explanation. Thank you. Keep posting more explanations.
thanks. This channel made it easy to understand how its work
What software did you use to create the animation? Thanks a lot.❤
Your video is very proffesional.Useful!

Can you make a video on how you made this circuit
Explain vibration technology in mobile or any devices sir
Plz explain all display technologies olds too
how does he makes so good animations... Any software ?
Hes probably using blender
Very Nice Bro! Get Good People!
Thanks for sharing this technology. Very interesting information. Keep going.
The polarizer porarizes light perpendicular to the chain of molecules/ the metal strings. What i mean is that the transmition axis for the polarizer isn't like you made it look like, it iz perpendicular
why the VP-filter allows only the V components & blocks all other while the HP-filter don't block the non H components.
Nice info, thanks for sharing it :)
