Polarized glasses effect on LCD monitor

I went to the cinema to see Avatar in 3D, and they let me keep the disposable 3D glasses. Here is what you see when a polarized lens is placed over LCD monitor of my notebook.

Does this happenen because the non-reflecting monitor screen is already polarized? So what happen is that if you put two polarized in two different angulations no light can pass, isn't it?

@BubuSnow93

You're almost right. Except this monitor is not anti-reflective. Its glass acts like a polarized filter, so when I put polarized glasses in front of it, I can block light when I find the right 90° angle. That's why this effect should not occur (I didn't try) on GPS screens: a GPS doesn't have a glass (or glass-like) screen, so it's not polarized.

Can you see a GPS screen through Polarized glasses when you're driving?

I believe that a GPS screen is usually of a different type. I don't know that name, but this type is not affected by a polarized glass. Nice question, anyway.

hello i need your assist

did you mean once i buy this polarized glasses like odinarly polarize and we can watching the movie 3D in polarize will effect same like cinema 3D ?? did this logical are same ? i mean did their work ? cause i have download Avatar 3D for polarize version but i had not yet buy this glasses yet . please help :)

@paopaowellwell

No, if you will buy polarized glasses you fill find them unuseful. Don't buy. You could watch a 3D movie only with special hardware, i.e. a set of all these three: (1) a 200Hz (minimum) monitor, (2) specific graphics card, (3) active glasses (NOT polarized glasses).

Haha, LOL @ pivotmaniac567 who thinks this is fake!!! LMAO!

Clearly has no understanding of basic physics and how polarization works...

[KarmaProdItalia]

@pivotmaniac567 Maybe you have never tried polarized glasses. It seems magic, but it's real!

[analpokemons]

what the fuck is going on here!!!!

im so fucking scared

[Kingmanification]

thats bloody wicked got to get myself polarised sunglasses yeah

[BigPappaGeorgio2]

Did a video on my channel explaining and experimenting a bit more with this concept if your intrested.

@KarmaProdItalia

Thanks sir

i though it was same logic can see through over polarized 3D movie :)
