Ben SandofskyBecause these billboards are just monitors rotated 90 degrees, they’re invisible to polarized sunglasses. It’s like a real-life ad blocker!

@sandofsky With the added bonus of not being able to see your car console while driving because that is also a monitor now!
Reiner Jung 🇬🇱 🇺🇦 🇪🇺@Unabart @sandofsky thankfully I do not need a car. Lucky me.
BTW this reminds me of the movie They Live

@prefec2 @sandofsky I love my car. I’m lucky I have one. It’s been a tremendous benefit to my livelihood. I would be fucked without it.
@Unabart @sandofsky This is unfortunate for you that you need a car and that they use screens with polarised light so many sunglasses can render them unusable. Unfortunately, this issue does not disappear with OLED. Of course this can be avoided with another type of sunglasses, but that can be quite expensive when you need special ones tailored to your eyes.
BTW thanks for reminding me of this issue. I would have missed that otherwise.
@prefec2 @sandofsky I don’t have polarized glasses. I can see everything as intended!
Tai xzo@taixzo @Unabart @sandofsky honestly I did not understand why, but it seems it does. I found multiple sources pointing that out and one that explained it. Also I did not find sources which claimed the opposite. However, if someone can provide a comprehensive and understandable explanation, I would be delighted to read it.

d.rsnfld@prefec2 @taixzo @Unabart @sandofsky Most OLEDs use polarizers and wave plates to reduce reflections which would otherwise come from internal components. You lose brightness (~50%), but gain contrast. This is one of the reasons why the efficiency of OLEDs is lower than one might naively hope.
Here's one model: https://optics.ansys.com/hc/en-us/articles/5845197523731 (Note that the front of the display is at the bottom of the diagrams, and unfortunately the OLEDs themselves are left out.)
CurrywurstJust one more reason to drive a classic car :
Physical gauges aren't polarized.
Then I'm really lucky. My car is old enough - not having any digital screens in it 😂
JTW@Unabart @prefec2 @sandofsky "I would be fucked without my car" says good things about your car in context, but bad things about the built environment produced by car culture.
@jtwcornell91 @prefec2 @sandofsky I don’t give a shit. I love car culture. What I do is none of your business and I wish people would just mind their own. All I mentioned was a silly quip about reading a car console with polarized shades and every bicycle ninny lines up to educate me about cars and car culture. Do whatever you want. I really don’t care at all. Just please leave me alone about what I want to do. Thanks.
@Unabart @jtwcornell91 @sandofsky The thing is, we live together on this globe. The everyone minds his or her own business is not sufficient. We have cars parked everywhere, people cannot use the sidewalk safely, people get run over while motorists think when they can't see a thing there is nothing, or they don't look and kill another person on a bicycle or a pedestrian. Cars also use a lot of space, the infrastructure is expensive. So prior 1 for cars will not do it.

baer@Unabart @prefec2 @sandofsky my point was just that lots of people who don't love their cars would still be fucked without them.
