I tried doing this with my 60in TV. Turned out to be alot heavier than I thought. Now my TV is dark with or without glasses.

Explanation: LCD (TFT and TFT-IPS) is made out of different layers, two of them are polarized films (between them there is glass/liquid/RGB/glass layer) that are differently oriented (horizontal and vertical). One polarized film is 90° turned around so that light can come through. So if you put another polarized film (layer, lens, whatever...) than the light can not get through if the polarization is oriented at the same direction as the top polarization on the LCD. Otherwise it can go through with small effect on the contrast. Amoled (oled) displays have only one ambient light polarizated film that regulates the contrast so if you put any oriented polarizationed film on top of it it has no effect. Q: But why are there some displays that are a little bit visible/colored when putting a polarization on it? A: It is because of the different light source wave lenghts that are comming through the liquid crystal layer Have a nice day

[@Driesipops]

just like onions... THEY HAVE LAYERS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

[@aayushkhandelwal4912]

Today i took one specs from 3d movie theatre and i found that both the sheets present on specs are polarized screen i took one sheet out and saw through it from changing its angle from one face it seems to become yellow and blue and from other SIDE NOTHING happened as its now become plan polarized. After that i put that one sheet on other sheet present on other side of specs when i put it and start rotating it changes intensity as I/2 and when i putted that sheet on other side i saw that it makes rainbow effect which is in high intensity and when i started rotating it other colors coming so how that is working . And ya i have one more polarized screen which i took out from my old button nokia phone and results are different this time it only changes intensity no color effects . Plz explain

[@squelchedotter]

Fun project: this happens because LCD displays have a polarizer built in for technical reasons (I suggest wikipedia). If you pull the polarizer off, the display becomes pure white. Wearing polarized sunglasses rotated the correct way infront of a LCD with removed polarizer effectively makes the sunglasses replace the screens polarizer. That way, anyone with polarized glasses sees the display normally, while anyone else only sees a white screen. - very fun project if you have an old monitor lying around

[@Ubundu]

The LCD panel is made out of the LCD itself and several thin layers of "polarized" film. These films are needed so that you actually see color as they reflect light at specific angles (think of a prism splitting the visible light into all the components so you see a rainbow). If you take apart an LCD panel you will find that the actual LCD is emitting only white light (rather that is all our eyes can pick up). Essentially the glasses act like an additional layer and depending on the orientation of the previous layers you will get a black screen. All of the layers are polarized at different angles and the order they are in matters. That is why with the glasses only at specific angles you get a dark screen. You should try rotating a full 180 each device as you might have missed the magic angle. Also the Fire tablet seems to be at 45 degrees where you loose the light. This effect is also used by the privacy screens you can get for your devices and allow light only when looking perpendicular to the screen.

[@joshie1984]

So, LDC screens contain a separate polarisation filter on top of trhe actual LCD glass sandwich. A polarisation filter is effectively bunch of horizontal or vertical strips that block reflected light from a specific angle, this matches up with the polarisation filter on the glasses and causes the effect. You can get nice polarised glasses from ali express around 10 dolla.

[@Rouverius]

Also keep in mind, polarized lens and some screen protectors can create some very strange effects. With mine, it's still readable but you have wavy rainbow lines al lover the screen where the surfaces of the screen protector and actual screen varies on some microscopic level.

[@georgewallot7739]

This was a helpful video and I learned something I didn't know. Thanks for sharing.

[@MattiaRighetti]

That's physics, waves and optics!

[@MegaManNeo]

That's quite interesting, never thought of such things to happen at all but still interesting. I admit that whenever I'm outside, I keep myself (or rather my eyes and hands) away from mobile devices but it's still a good fact. Sunglasses don't like LCD screens all to much.

[@MartinBenek198]

Wow, that's amazing!!! NIce video man :-)

[@robertbidochon7949]

+Jordan Keyes Very well explained effects, thanks!

[@joshlawls5899]

I assume these glasses are very expensive since you advise us to buy a phone to suit our glasses instead of buying glasses to suit our phones. lol

[@JordanKeyes]

+Josh Lawls Well, in my case they're prescription glasses, so they're more expensive than a lot of the phones I own... but I review a lot of budget (< $200) phones. If you're just using polarized non-prescription glasses, yeah, buy what you want.

[@ozkarsandyballs8011]

+Jordan Keyes yeah...what Jordan said so if this video is too much for your tiny brain to handle...move along brighteyes

[@mariopuente6480]

Josh Lawls point well made...sunglass industry is a joke

[@bayybars]

You can buy them as low as 12 dollars lil normie

[@epion33]

Not if they're authentic Italian quality.

[@nicholasledoux7840]

I have a samsung and my sunglasses does the blackout thing... I learn that last few years. its all in the wavelength vs the color shifts in the transparency... but still learning myself

[@anneketaylor17]

For my phone, it makes it rainbow looking

[@Souls4Roca]

the brand i use has vertical lines so i can see on phone screens unless sony panels in portrait

[@TheMickvee]

My prescription Oakley sunglasses are polarized, but as I don't use a smartphone, I was unaware of this side effect. However, I am aware of the weird effects that are produced on car windscreens!

[@rickliang]

Killed it, this is a unique tech video. :)

[@Barkingspider]

Would you recommend have a pair of polarized and another pair of non polarized?

[@epion33]

Good to know my RayBan P's will work with my iPhone X. Was worried if the OLED would make it better or worse. Thank you!

[@Scott-K7sce]

i've had polarized for a few years now. it does have effects for phones etc. but one thing it also effects is other electronics like car stereos, ham radios digital dashboard gauges, also colors of said gauges. my cars stereo is green readout. one ham radio is also green readout. with glasses on all is see is blacked out. i have to flip the glasses up to read those screens/readouts. on the dash...

[@kevinpatrick3280]

There are polarized plastic lens sunglasses available in many retail drug stores that are under $20.00, just not many from which to choose.

[@Tiger__]

well, good thing I can see close. it does with the light ray.

[@davidcrowe8752]

the darkening effect is caused because, anything with an LCD display has a polarized film on the front and back of the screen, so it adjusts to movement like polarized lenses for cameras.

[@getgiveknowledge8855]

If we want polarization test which type of screen should have our mobile

[@daffdill978]

HI...what's the story with polarised and iPhone? Thank you :O)

[@talol90]

I have been searching for an answer for this matter for many months and i even asked many people about it but no one was facing this problem ... And finally i got the answer now from you ... I have xaiomi phone and it always dims when i flip the phone while i am wearing the sunglasses

[@awesomefacepalm]

I don't know much but it has to do something with the light waves from the screens. I guess your glasses are blocking vertical (correct me if I'm wrong) light waves. And apparently some screens sends out light waves that only one polarity so thats why the glasses cancels out the waves.

[@GlaciusDreams]

What about vs a TV? What kind of sun glasses can make a TV black without changing any of the settings on the TV?

[@JonathanMoosey]

I was trying on some polarized sunglasses versus nonpolarized sunglasses and the Face ID on the Apple iPhone X only works with polarized sunglasses. Don’t believe the iPhone XS will be any different. As for the screen viewing, I haven’t noticed any difference as in screen viewing since the iPhone X has an OLED screen.

[@charlestonvillamor4509]

Watching this using my polarized sunglasses 😄

[@kittendivine1]

Does it change anything else or just screens?

[@arncj18]

mine only go dark if i turn them 45 degrees up onn the left side. Was wondering if the coating expires and can be reapplied?

[@hitardo]

Had no idea this happens. Thumbs up! :)

[@bestsellerwithkitong]

I’m having difficulties looking at the screen of my 13promax because of the rainbow effect, is there any chance I can fix it or does screen protector affects the effect? Cause when I tried to look at my sisters phone which is 13 pro, there is no rainbow effects tho she is using matt screen protector, Im not sure If I need to get new screen protector, please help thanks!

[@bcloud78]

Very interesting, thanks for video, great.

[@icucmeicu2]

polarized sunglasses or prescriptions are the best for driving what have you used before?

[@subbiahpalani]

These kind of videos are awesome! Some unexplored territory!

[@GzzLuiz]

Theory of light. pretty explored already. Thank Maxwell for it (not polarozation though; for that, thank the creator of Polaroid).

[@PaganiTypeR]

+Subbiah Palani Ramalakshmanan this is quite well explored and is being used in monitors to shift light. So that you'd see colours on your screen. Polarization is basically acts like a filter, depending on which colour needs to be projected it filters out all the other, unwanted colours. There are more applications for polarization, that's one of them. And it's super easy to understand how it works. KZbin is full of explanation videos.

[@davidkrump9446]

Not all phones of one model are the same. I love my (expensive, prescription readers lenses) polarized sunglasses and never had a problem with any of my smartphones until I broke my HTC One M8 and bought another one. Apparently, the glass is turned 90º on this phone compared to the one I broke because I can't see it in portrait mode with the polarized sunglasses unless I turn it to landscape mode. I had to buy new, non polarized sunglasses. Bottom line, try to look at the phone with your glasses before you buy.

[@abhijeet1in]

Brilliant. I had no idea!

[@betozOfficial]

Hello i use poco f1when i turn my phone screen to vertical orientation it becomes dark but when it goes to horizontal orientation it turn more clear. Can any1 help me?

[@AshimKundu]

Thanks for updating

[@electrictoxic80]

LCD is in fact using polarizing technology to make different colors. A LCD screen polarize the white backlight, that is, subtracting the certain wavelength of the white light so that the only desired wavelength (color) is shown.

[@rdkuless]

try the Oakley Prism (non-polarized) lenses. They are a different tech that filters waves of color differently.

[@41292wolf]

I know this is about polarized lenses, but I must say, your home looks very nice. Love the floors and the design of the desk. Just want to spread nice comments in such a negative world.

[@KRLEEQ]

The polarization orientation of the lens is vertical?

[@scottchoi2720]

wow. thank god I watched this b4 I ordered mine...Thank you so much

[@antirkselloyana7642]

Your sunglasses are nice. What is the Make and model number of your sunglasses?

[@Wehra96]

my iphone just gets very blue tinted unless im looking at it sideways then its allmost completely normal but my pc monitor goes black at the angle my iphone gets normal.

[@chrisken1668]

the displays that turn black already have a polarized layer in the display, you cant polarize light twice very well, but if you remove that polarized lins from the display you will be the only person that can see the display with polarized glasses

[@Snowmation]

Good info, thanks.

[@yahzest]

I watched your video bit too late. I picked you a sun glasses (polarized) and its not good with Nexus 5 :( ...... i hope i can get it changed now.

[@dathyr1]

My LCD 40 inch TV and my Motorola G phone does this polarize effect with one of my sunglasses when I rotate the glasses. So at least I know the polarizing feature of the glasses work great. Thanks for this simple test.

[@AureliusR]

The reason this happens is because LCDs have two polarizing filters in them. This is fundamental to the way they work. The reason the Samsung one works is because they use AMOLED technology, not LCD. EDIT: Wow, you said that in the video about 2 seconds after I typed that :P0

[@ruinfirefly2088]

okay, little bit information for you guys, polarized sunglasses block the light rays in a specific angle therefore only few days enter your eyes as sun throws light in all directions, you receive light in only one direction. Old black glasses just lower the brightness but polarized sunglasses block the rays entering into the glasses, thus protecting our eyes. I hope this information help you guys to choose better glasses.

[@RandomYTTroller]

Dibbendu Koley you have no idea what you are talking about son

[@dvxAznxvb]

Polarized protects against lens flare elements and reflections like sunlight with water on windshield can effect vision All sunglasses reduce brightness because that is their general purpose

[@harimoturi583]

1:40 time on phone...is that a good number if we see it again and again..unintentionally..

[@PREMKUMAR-qq6pk]

does it works in lcd dispaly only i think

[@7secondcentral244]

what about iphones. do the glasses get darker?

[@Karmakaze]

Hi there ! What brand is your sunglass? My Ray-Ban doesn’t do that.

[@abnrs]

good n best information for me thanks alot n so much

[@sudhirmv]

Good information about polarised sunglasses

[@willyyale]

if you use spy happy lenses that are polarized they work fine with lg g4

[@MrStephenbell]

The sensible thing would be if either the phones or glasses were polarised on the diagonal, as noone views their phones diagonally. Polarisation is typically done horizontally or vertically and blocks wavelength in one direction, hence, it goes black.

[@RockyGrenade]

I bought one of these without knowing anything about them. Basically the "Polaroid" being different from normal sold me. But when I wore it for extended periods I realised that Polaroid eyewear is pretty unique. I would say everything that they advertise is pretty true. Its a real pleasure to wear them. They are the very first brand I went with for a serious purchase. Previously, I did not quite believe in wearing shades, cuz they hide your eyes. But from now on i wanna wear my Polaroids as much as possible.

[@singular9]

I just came back from a cruise in the Caribbean.... Yeah found it hard to film with my phone in landscape with polarized glasses.

[@zainnyztv986]

this helps a lot actually!

[@Ruisleipae01]

This is a effect of maulus law. Basically the amount of darkening on the screen is caused because the screen is only emitting light polarised in one direction so it gets blocked out when you turn the glasses polarisation at a 90 degree angle to the phones emitted lights polarisation.

[@rockorsomething2397]

I've used laptops screens and polarized glasses to see if glass is tempered or not before

[@Ian-de5fl]

My OnePlus One goes completely dark when I use it as a GPS sideways. I can't have polarized sunglasses in my car.

[@bilalchekhab]

how can i make it ?

[@rhonielsoriano8091]

thanks..it helps much!cheers

[@RobertoPlays]

Can I wear a polarized sunglass while using for hours a computer? will it have positive or negative effects?

[@pralhadmaskar5064]

Which lens u were sir?

[@sneekylinux]

Hey mate, sorry i have been away for a bit but to let you know ive gone to multi-focal contacts, best thing ive ever done as you can use normal sunglasses, but they are not for everyone..nuff said

[@sneekylinux]

***** thats a bummer man

[@linuxjrm]

Sneeky we miss you man.

[@hassanila]

THANK YOU so much for this video! I have a Samsung Amoled display and don't need to care!

[@blogciaga4680]

it would be better to mention sunglasses model. can anyone tell the model of sunglasses?

[@chawkamhoe]

LCD or LED screen use Polarizer to control pixel brightness over a constant white backlight. LED screen is just short for LED white back light for LCD screen. While LCD use a Flash lamp for white back light.Samsung use AMOLED technology. Individual Pixel is an LED control by current and no polarizer in front. and it consume less energy.Good to be able to check the effectiveness of the polarizing sunglasses with some phone like G4

[@ericsoucie2865]

What about televisions?

[@neon_one]

I can't figure out why 2 polarized lenses are hard to see through but 3 you can see through like there's only 1. I suspect the image is being reflected away from your eyes with 2 layers but the 3rd layer catches and redirects the light to your eyes instead of off to the side. idk but try it out if you have 3 polarized lens. It seems like magic

[@Q8Patriot]

Thanks great video

[@Lone_Wolf79]

What model Ray Ban?

[@RisinT96]

Yeah, you could do the same with some computer displays, depends on the polarizing layers they use in the panel. (If you remove the layer then you get a white screen and cannot see anything).

[@RisinT96]

***** It wouldn't always work since different panels use different types of polarizing filters (linear/circular). What you could do is remove the polarizing layer from the display, cut it and put it into glasses frame, then you'd get a screen only you can see (if you hold your head at a certain angle).

[@IamMananPatel]

Due to unpolarized light is making 90 degree on polaroids thus the intensity of light is half or sometimes zero .

[@thomasalias8492]

I wonder if tesla thought about that when making their giant touchscreen display in their cars. Someone should test it.

[@spiral9316]

Tom Foolery car glass is also polarized AI the probably did think about that

[@mairahdz5425]

+Spir Al kolerollsas

[@Miumiu0404]

I just ordered a polarized sunglasses online and now I feel like I made a huge mistake. Do smartphones released from 2020 and beyond get affected from looking through polarized lenses?

[@gotnoshoes99]

Light is made of photons which oscillate, some up and down some back and forth and just about everything in between. Polarized lenses allow only photons that are oscillating in a particular direction to pass through.

[@saillei1808]

Give me a way to test my clip-on polarized glasses : )

[@aerodicus]

I looked at my iphone with polarized sunglasses on and theres a big spiral with what looks like the eye of Sauron looking back at me in the center.

[@shakir-abdullah]

How many phones do you have..?

[@alexzhao8424]

One of my friends got a pair of polarized sunglasses for driving. One day he needed to go somewhere new so he turned on his gps. Then, there was a panicky moment: )

[@jamezbond78]

When you take two polarized lenses the light gets canceled out. The lcd screens on some phones must have a polarized lens.

[@jollyroger61]

Good stuff Thanks

[@evangraveley7625]

When you relize you have no idea why your watching this.

[@Quephara]

Actually, as a pilot, I have to know how to test for polarization in those and take the non polarized otherwise we're going down

[@riseeace5016]

Agree

[@amranihamza3857]

its very usefull for me , because i'm using polarized sunglasses (Gauss) and i see nothing with them on Xiaomi note 5 pro

[@amranihamza3857]

try to rotate your glacess in front of your secreen and see it becomes black,if its so , they are polorased.

[@yasyasmarangoz3577]

yes

[@tommybnc2910]

what is the difference between lens who goes complete dark and those who close to dark but u can still see the dispaly phone

[@lanunselatable]

It's the different display technology use by those phones. The LG phones used LCD display, which control light by manipulating the polarization of a liquid crystal. The Samsung phone use the AMOLED technology. It's basically a LED, an array of a very very small LEDs.

[@nanoblackz]

I notice polarized glass will mostly affecting your view to LCD screen with IPS tech.

[@I.C.Weiner]

I have found the opposite. My phone and laptop are ips and all I get is a slight dimming and a cooler color temperature. With my TN monitor it goes black at about a 45 degree rotation and my VA TV's go black at 90 degree.

[@RamirodeSouza]

Did you try the Pebble Time or something that uses some type of E-Ink display?

[@RobinJ]

Ramiro de Souza E-ink displays are pretty much the same as paper. Pretty sure it won't have any effect on those.

[@ContasYT]

My Huawei P8 Lite doesn't get black but its allow with rainbow colors, honestly it doesn't bother me its just pretty so xD

Ooooo I like this video. Nice job *****!

[@joecachia2]

Big discovery. we used to do that in the eighties with old calculators. Some people use this technique to reverse screen colours on Casio Watches.
