Sir, next time make vedio about petrol pump machine how they work

[@bestowicprimer8835]

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.

[@bestowicprimer8835]

Can I request a video on Heating and Cooling?

[@zesanurrahman6778]

epic engineering indeed

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

[@warmon6]

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.

[@flynn3649]

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.

[@eSKAone-]

And if the polarization filter could really block all the light we could achieve true blacks like with an OLED

[@Emperial_X]

Dam right! 💯

[@sschueller]

Yes, correct would be to also call them that. LCD with QLED backlight.

[@sammyapsel1443]

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 !

[@raiden72]

We don't deserve lesics! His channel is too good :)

[@nibirsaikiya4990]

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

[@crowned-blue]

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

[@nothing9220]

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

[@DrR1pper]

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".

[@rajashashankgutta4334]

LED TVs are lcds with led light background

[@omniyambot9876]

yeah lmaooo

[@muhammadbilal2000]

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.

[@gizmoknow-how2022]

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!

[@BlurryFace-zz2ro]

Been watching this channel on KZbin for 2 years now and I have learnt so much. You guys do amazing work! Hope I can fix something someday.

[@nalinsaminda]

Explanation is next level with Animation ❤️. Thank you for sharing.

[@devilwatcher5766]

One of the best and coolest explanation I have ever seen!

[@gohangoku3447]

Very useful vid. Please deep dive also in twisted nematic, inplane switching and vertical aligned LCD techniques to visualise their pros and cons.

[@unknown4_4]

Hi...... I love your videos soooo much..... They are awesome and very clear to understand

[@aravindang7475]

Very good explanation. Thank you. Keep posting more explanations.

[@DB-nl9xw]

This is one of the best explanation I have seen. I wish I could understand how to get lower values of the rotation.

[@Valdaemonium]

Nice video and explanation! I missed some talk about quantum dots/nano cell (same, just different names) which enhances colors on LCD screens, and some talk about IPS and VA types.

[@user-ip3eh1hv6s]

Love your explanation and efforts ❤

[@skabbymuff111]

Fantastic explanation. Magic explained.

[@ranjanjoshi3454]

Thanks very insightful and informative

Perfect, Thanks for sharing .

[@aresivrc1800]

Brilliant video as always! 🙂

[@gamesapp22]

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 👍.

[@DrR1pper]

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).

[@saishivakoneti1876]

Great explanation.Please do a video On working of RF transmitter and receiver modules and all wifi modules.

[@YFTOUCH]

Your video is very proffesional.Useful!

[@Matescium]

Dude, your video is awesome. Good work ...

[@sciencerelevant4588]

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.

[@puspamadak]

[@varunentertainmentnetworks2670]

It was informational lesics, I wish to see a video on functioning of Car remote (key)! Thanks in advance

[@joshuacaylor881]

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… 🤯

[@jerem_fl]

Great video ✌🏼 Small detail: when unpolarised light goes through a vertical filter, I think only the horizontal component will be transmitted (not the vertical) 😃

[@you2be839]

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...

[@eqXzeRt]

Thanks for vid. Little correction: 2:47 - the right direction of e/m wave propagation is opposite.

[@gnryushi]

Thank you for this.

[@rameshhariharan2623]

Super explanation, great if u could mention about pixel in tv screen its role in dedign of film photos vonversion to fihital pixel , whether it depends on each tv or moniter screen size

thanks. This channel made it easy to understand how its work

[@loikvokhidov7688]

Absolutely awesome content, i learn a lot from these videos. I wanted to ask if the voiceover for ur videos is AI?

[@naveenkumarn9917]

Finally found someone who can explain in detail how LCD/LED works

[@kotapatiswaraj06]

Woww ! What an awesome explanation.

[@riteshyadav7157]

Video request/suggestion- How does a CCD camera works. Or how does colour cameras work. History, basics , applications.

[@mzmz9355]

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).

[@Bianchi77]

Nice info, thanks for sharing it :)

[@rollercoaster3freak]

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

[@gkrees9509]

Right!??? Like how do these individual ARS’s know how or when to rotate the light source to make the image that is required !?

[@joseville]

processors are manufactured using microlithography so I would imagine some of these elements are manufacture using a similar process.

[@qwertydavid8070]

@@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.

[@Dr.Kay_R]

Use the image in 4:49 as thumbnail. Also mention that *it's actually LCD!* You would get more views.

[@rahulkurup61]

Best video to understand

[@neuvil]

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.

[@varunentertainmentnetworks2670]

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.

[@brittonwise2203]

this channel is SO underrated

[@samuelmendoza9356]

Regarding the LED backlight, just to get accurate black, why not make the LED backlight to also operate like old school LED screen, where dark pictures don't illuminate or partially illuminate?Granted, this doesn't solve the size limite of LED where they can only be a portion of a millimetr, but it should allow distinct blackness compared to what the usual LED shows. Is this system been done before or is not feasible?

[@ethanebang8902]

Wait lesics got a sponsor Nice one congratulations

[@mitukumar6066]

Very difficult technology but intresting vedio

[@a.h.m.shakilaktar6781]

thank you so much

[@rubabmubarrat]

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.

[@ateequrrahman4684]

I knew it already. ..but not so detailed, very well explained 👏

[@niklasgs1470]

That's awesome can you guys make a video on how micro led works?

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

What's currently stopping MicroLED screens from rendering all other screens obsolete are the need for further pixel size miniaturization and cost. Once these 2 main issues are overcome, OLED will soon go the way of plasma screens.

[@CannabisTechLife]

In the mean time you take the inconsistencies that already exist between each individual tv panel and slap those together as one unified panel. I've seen so many of these types of tvs have random warm panels mixed with cool panels, have some panels just fail so half the tv is dead, etc.
