Internal structure of a liquid crystal or LCD TV screen 

The thing that blows my mind is that the circuitry to control each pixel is placed behind the liquid crystal, yet is transparent enough to let the light through. How can they print circuits that small? Seems like magic to me.

Fantastic video. I learned a ton! I had no idea that's how an LCD worked. Thank you for sharing.

I have no words how much I would like to thank you!

Your video, animation and explanations are awesome.

Great video. Always learn something new from your videos thanks for your effort. God bless you

This is the best explanation about the technology itself in Liquid Crystal Displays. Hope there's another one to talk about several changes which improved this technology to almost match with OLED types: The gain of contrast ratio; others LC types, as VA and LTPS; the FALD in miniLED for backlight etc. A question I have for Color filter on this screen, is: how do they get the acurate RGB pixel to show pure colors nowadays? Since oldest LCDs were so wayoff, in exhibiting blend colors, and now we have deepest reds/greens/blues we never saw before? If it is just the Quantum Dots layer, or if color filters are made with deep/solid RGB pixel? ...

Woah, great video mate!

Wow I never dreamed it looked like that, thanks.

Amazing video. Thank you very much for this information.

Thanks for best description about led tv internals structure

Thank you very much. I hope to get more beautiful videos

Wow! interesting & Very well Expressed.

not everyone understands the point of the capacitive structure. the point is that the E-field in the (idealized) infinite flat plane capactior that is created by this structure induces torques on the nematic liquid crystal aggregates (through the capacitor's electric field interacting with the dipole of the molecules, in the most simplistic basic idealized approximation obviously, everything "neat and nice and clean" and capable of being modeled with 1st year university calculus, lol). In practice, the important control input is the switching of the capacitors. A tremendously critical part of LCD development has been the capacitor "cell" optimization, and less about things like the light source (which is almot 100% of the focus in OLED research)

Sir Vere Vere supper sir. iam 📺 Work very very useful sir. Naxt video waiting

if theres a vertical and a horizontal polarizing filter, what else passes through that makes the screen not black? if they block everything?

Very nice.Thanks

Thank you

I like your videos 😊👍🏻

Very hard excellent explain

Thanks

why does the liquid crystal make a pattern when it leaks

Why some LCD screen comes with a poor red and green pigmented resine, causing the display to show colors in a strong blueish tint? Poco x4 gt's LCD shows deep red and green, but most LCD (like on the moto g8 power's LCD) reds are orangeish and greens are so off...🤔

you are great

Very good

Sir please explain the panel fault like double image why that happened what is the possible solution and how long it will work after service

Nice video sir,

good video

Good day Sir pls. can you explain why the lcd screen turn to double image & flickering image thank you & God-bless

Super sir thanks 💐💐💐

2:01 you say cholesteric have twisted structure and Nematic have common orientation, yet no structure. Then in 2:14 you said Twisted Nematic is used in displays. Why take unstructured Nematic and do something (like anchoring layer) to twist it when cholesteric is already twisted? thats one question. second question is ... you said there is no layerwise structure in Nematic. then how come when you use the anchoring layer, the successive layers of moleculeas further and further away from the anchoring layer tries to align with the first layer right next to the anchoring layer? without this aligning tendency, there would be no twist. so TN have aligned layer or not?

Hello, I'm trying to create some electronics to test the LCD hub, but it is hard since they have a camera and microphone. Do you have any idea how to do this, something to test the LCD hub, backlight, microphone, and camera

Awesome @3:17

Exelentes videos pero serían buenos también en español

👍👍👍👍👍👍

What's the function of the LCD bezel? Can I cut half of the upper side of the LCD to reduce dimension and resolution?

Hello, Genius, I'm getting a big doubt about LCD/LED TV's COF IC. I'm not getting any idea about this, because, I don't have a Microscope or DSO. If you are interested to help, please take a small test about this COF with IC & without IC. Everybody knows all signals are coming from the T-CON board to the LCD panel with the help of the COF bonding method and its signal testing points also given in this COF. But, why need this COF and what is the role of this IC? This IC's data is hidden or this is not an IC. Please clarify the truth about this COF.🤔

I have request to you plz make a deatail video about the detail and working of COF. Thanks❤️

Thank you sir..

Please hidi language

Por qué no se subtitula al español?

Please upload new video. We enjoy

this wouldve been considered witchcraft 25 years ago. Fascinating

This makes it more appalling (besides sheer waste) that certain TVs are considered "disposable".

Please take a pilipino language translator

white is not a colour!

Very breaf explain

😴 😒 😂 hello!

DO ALL SUBPIXEL ( TRANSISTOR ) MOVE CORESPOND WITH ICON MOVEMENT...?🫣😎🤔

Very good
