The CRAZY PHYSICS of LED Displays! 

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

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.

Can I request a video on Heating and Cooling?

epic engineering indeed

@@bestowicprimer8835 Thank you for the compliments :)

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.

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

Dam right! 💯

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

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

LED TVs are lcds with led light background

yeah lmaooo

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

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

@@nothing9220 I can really feel the pain you experince

@@crowned-blue that not true. not always

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).

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

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

@@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.

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...

Thanks for the second trick
