iPhone 12 Is iPhone 12 still using PWM OLED?

I'm not qualified to answer this precisely, but apparently the flicker you can't see still affects your pupils by causing them to suffer fast multiple contractions and expansions in rapid pace if that makes sense. For people who suffer with this, it can be very dangerous, headaches, sickness, vomiting etc.
Oh wow that’s crazy. I’m glad I don’t suffer from that but I feel for the people who do.
The eye takes in the flickering light but the brain isn't capable of processing it. The discrepancy between the two causes the internal balancing mechanisms to screw up, followed by symptoms of headaches/vertigo/dizzyness/eyestrain etc.etc.
In my experience if you try to ignore the symptoms it can lead to further medical issues.

For those of you who are having trouble with all of the new phones (i.e. even the SE and 11) and are on a iPhone 8 or earlier, what will do you if your phone breaks?
For those that have trouble with PWM alone, what would you do if you needed a replacement? 2020 SE?

worth noting there was a report of a new apple supplier (BOE Display) in China ramping up production of OLED panels for the iPhone 12. They seem to do a lot of glass based and 3D printed flexi OLED panels, so we could be looking at different PWM behaviour to the Samsung OLED's.
If it's there then the eye definitely see's it, even if the brain doesn't conscientiously process it and therefore not aware of it.
I just watched these slo-mo videos on a 12pro: it’s feeling a little masochistic. Especially because I know these OLED screens flicker; I know I’ve had problems with them in the past. I know I keep trying to will myself to have no problems. But there’s a voice in my head that says, “Even if you decide to will it to not bother you, do you really want a phone that is constantly flickering at you? Especially when you can have an older ‘less cool’ phone that doesn’t flicker?”
I love and hate that voice.

I've been using OLED phones for the last five years. Both Samsung Galaxy Notes. I was disappointed when manufacturers started moving away from LCD screens. Sure they have their share of problems with things like uniformity, but they are (IMO) a better solution. And I've seen my share of uniformity issues with OLED screens as well. And OLED has screen burn-in. You should see my wife's three year old disaster of a phone (also a Note). I don't know how she can stand staring at it with all of the burn-in her phone has. I wish that OLED would just go away and that it was at least possible to find more phones with LCD. I'd buy it over OLED any day.
This is the year that I switch to the iPhone (holding out for Max). I've always had Android phones since the HTC Evo. I'm hoping that I don't have any problems with it.

How would you find out when the holiday return policy starts? I looked on the website but couldn’t find it. If it started last year on November 15, would it be the same date this year?
For guys who feel sensitive to OLED, my experience is I tried iPhone 11 Pro for 5 to 6 days, until I feel the discomfort in my eyes and couldn't even focus; since I still kept my iPhone 8P at that time, I feel instantly eye released when I switched to iPhone 8P screen, that's why I was pretty sure about the cause. And I end up with iPhone 11 now, which is good so far.
If Apple continues this OLED run for future iPhone, I may have to say good-bye as a loyal user since 2008...

Just got a 12 pro... It's effortless to use the screen. I don't have an oscilloscope so I can't give your the frequencies in play but pwm has wrecked my world and this panel simply isn't a problem for me.
For what it's worth.

I haven’t read too many of your past comments- but how bad was your pwm sensitivity with other phones?
My experience with going from 11Pro to 12 Pro this year was a bit of a disaster. My eyes won’t stop watering and I find focusing oddly hard, even though the display looks very crisp and clean.
My daughter bought an identically specced 12 Pro, even identical color, but her display looks a tiny bit more contrasted and crisp. I don’t know if that one would have worked out for me, since I would kind of need to try and read several pages on a site like this one to start feeling the effects. But she’s too busy with school and work to lend me her phone that long. She has had some dizziness and headaches but she also had three vaccines that produce those side effects. She says she doesn’t seem to have any eye strain.
The minute I return to my 11 Pro screen, my eyes are fine.
I think it’s possible in time I’d adjust to the 12 Pro display, but to my dismay something about the weight and the way it’s distributed on the 12 Pro cause some nasty carpal tunnel like pain in my hand that’s as bad to deal with. Lol, I’m just a mess!
iPhone SE 2 was NOT a solution. When I use that phone for awhile I get a white shimmer at the periphery of my vision. I’d love to ask my eye doctor about that, but Covid numbers are spiking here. It will have to wait. So I offered my SE 2020 as a trade in to help bring the 12 Pro price down for my daughter’s phone. She’s using her own earnings on it, but I wanted to provide an assist and can’t really use that phone anyway and nobody else wants it over her old Xr that has the larger screen for games and FaceTime. My daughter is hanging on to her Xr in case she does find OLED problematic.
My option is of course to keep my 11Pro. And I may end up doing that, but I’m reluctant to give up the new wide angle camera that produces no distortions. So I will try one more time with a regular 12 or a mini. The new Qualcomm modem also really makes a difference out in the fringe service area I’m in.

That’s extraordinary that you were okay with the 11p screen but not the 12p: that’s not the way we want the screen problems to go! It’s good that you still have the 11p to compare (as opposed to just your memory) and good that you can back to it, if need be. Hope you find something that causes you as few problems as possible.
It’s a way screen manufacturers dim screens that causes them to flicker and it can irritate some people’s eyes and cause headaches.

Hi, I have a 2020 iPad Air and SE2 (2020): How can I help out here. What settings should I test?*Unfortunately, (At least for me), it’s more that the A12 introduced the problem and it has been bad ever since. The iPhone 11 (A13) was just as bad. I suppose it’s possible the A14 chip fixed the issue (we could figure that out if someone tests the new iPad Air), but there are no A14 LCD iPhones even if it was fixed
I haven’t been able to test the SE 2020 yet, I’m very curious if it causes the same issues as the XR/11. If it does, it would seem more likely that the issue is the chip introducing some kind of flicker.
No issue with the SE2 and my vision.
*I haven’t owned OLED iPhones and did not follow these threads closely.
I think the consensus is flawed to avoid these screens, only if you have symptoms and if not, you are fine. I would assume its terrible for your eyes even when you are not sensitive to it, especially when you look at that screen for longer periods of time. Like come on, to focus at something that constantly flickers does that feel right for you?
Being a biologist myself, I seriously doubt the iris can contract and decontract (both active processes controlled by different neuronal inputs) at this pace. Actually, I seriously doubt that a frequency of on/off light above 200 times per second is going to be noticed at all by your brain. For comparison, a LED light can flicker at about 100 times per second (sometimes lower) and not be noticeable (or sensitive people get consistent headaches at night upon LED illumination?). Anything above 90Hz is essentially unnoticeable.
Any actual scientific evidence of that. What internal balancing mechanisms? How is the brain not capable of processing light? What further medical issues?
