Please make the music lower next time. Otherwise, it's a perfect explanation 🎉

That is a very concise explanation --- IF one is an electronic technician.

Everything else I comprehend but I have not been able to construed where the magnet field is applied to turn the liquid crystal displays, after all it must be very precise in terms of how much of each individual crystal you would need to turn to form a specific color. But other than that this was a very nice explanation of how an LED TV works. :)

polarization (key concept) = the direction that the lights go up and down
without polarization the lights go in all directions the trick with the tv is that you have to control the directions with polarization panels
2 of them are used in a lcd panel, they are placed in front of the led backlighting. only vertically polarized light can pass through the first filter and not the second so if the light doesn’t go through the screen how do we see the image this is where the lcd’s come in (LCD = Liquid Crystal Display) are molecules that are naturally twisted 90 degrees when light hits them they curve around and that makes them able to go into the second filter/screen (the more voltage the more unbent the degree of the lcd is)

How do they make it? How Production is done

This is so well made! Inspired by the minute series?

Are the pixels the final layer of the screen? Why do they need polarizing filters for the backlight if the pixels control all the colour? And why do they need LCD crystals to bend the light through the final filter (why not just omit the filter entirely)?
