Internal structure of a liquid crystal or LCD TV screen

[@kentslocum]

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.

[@AnsariElectronics430]

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

Your video, animation and explanations are awesome.

It's amazing how thin screens can be made. 🤯

Thanks for best description about led tv internals structure

[@noreezy4991]

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)

lcds are incredibly advanced tech compared to oleds, if i have got it right. the old analogue crt tvs were a fantastic ingeneering accomplishment as well.

[@nbursese]

Amazing video. Thank you very much for this information.

[@thedistinguished5255]

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

[@nagiaachou3618]

same question

[@JohnnyOU08]

The crystal reorients the light to pass through the final filter.

[@jeramirezpa]

The polarization of the crystal.

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

[@RedDeckRedemption]

Haha fear not, a lot of these don't actually end up in landfills. I'm one of many who hunt for TV's for scrap lol, steel, aluminum, copper, and the electronics for gold/silver recovery, and the LCD screen contains indium. Apartment dumpster ar as are rich with them

[@sagarneupane7706]

Nice video sir,

[@NishanthSalahudeen]

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

I will think about it

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.🤔

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

[@elearningélectronique]

The TV bezel is the frame around the screen. It's what holds the screen in place and protects it from damage. Never cut an LCD screen because it will end up in the garbage

Por qué no se subtitula al español?

[@elearningélectronique]

la razón principal es que no conozco el idioma. Eventualmente podría utilizar un traductor en línea para hacerlo.

[@antoniomartinezlopez2183]

Hay muchos colegas que preguntan lo mismo. Es muy importante para nosotros los técnicos reparadores hispanos que por lo menos el vídeo traiga la posibilidad de subtitularlo al Español
