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.

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

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

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 !

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 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

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!

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… 🤯

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

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

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

Perfect, Thanks for sharing .

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

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

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

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).

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

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.

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

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!

Love your explanation and efforts ❤

Woww ! What an awesome explanation.

Thanks very insightful and informative

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

Wait lesics got a sponsor Nice one congratulations

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

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.

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

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

Fantastic explanation. Magic explained.

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

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

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.

Brilliant video as always! 🙂

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

Your video is very proffesional.Useful!

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

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.

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

Thank you for this.

Nice info, thanks for sharing it :)

amazing information 👌 thank 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) 😃

@you2be839

2 ай бұрын

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...

Only put a drop of water on phone display(with white background) then pixel will be visible.✌️

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).

Great video again Sabin. I really liked one about the inkjet printers. Are you going to make one about laser printers as well?

Thanks for sharing this technology. Very interesting information. Keep going.

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

What software did you use to create the animation? Thanks a lot.❤

Thanks for sharing the knowledge..

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

Very difficult technology but intresting vedio

Can Lesics make a video on how the differential lock works?

Best video to understand

really amazing video

this channel is SO underrated

thank you so much

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

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.

Thanks sir

Hi sir please tell me what softwares or apps u use to do animation videos in KZread.... thank you sir , i hope you will achieve the wonders

Pls make vedio on lcd working principle

Please make video on additive manufacturing technology

pleas can make a video about old processor and a new tech of processor

Explain vibration technology in mobile or any devices sir

Thanks!

Beautiful

Sir, please make a video on working of computer.🙏🙏

This is great!

It helped me

Thanking you till next time...

Plz explain all display technologies olds too

Wonderful teaching with great animation. highly appreciated

make a video on Oled, amoled etc types of displays

Please describe about electronics control panels..

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?

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
