iPhone 12 iPhone 12 is flicker free(DC dimming)!

I was OK with the xs with white point at 90% setting and brightness up, but would still get the occasional migraine from looking at the display. Just from a brief time using an 11 the display looks better not having to use the white point settings, so thinking about going to an 11 if the 11 pro max or 12 pro’s aren’t an improvement over xs
I was at a store today and looked at the 12. I took slow motion video if it (from my iPhone 11), at 100% brightness there is still a pretty substantial flicker. 
Unable to attach the slow mo video, I will work on that in a bit and do so- but just wanted to share the disappointing news. The flicker at 100% is no better than it is on my wife’s XS Max.

- PWM is a fact on the iPhone 12/12pro
- What we still have to discover is, if it is at the same hz as previous version. We will see this when Notebookcheck will review.
- Besides the PWM, there are several reasons why we get eyestain, migraine etc.. from the display.
I posted this to other topics too, but I found this measurement for the iPhone 11 pro max. If it is correct it would indicate that PWM would be at lowest on 50 percent brightness. That is if I am interpreting it correctly.
Have you tried fixing brightness to this level if it would help?

I do remember this with the iPhone 5. Some displays where very warm in tone and other very blue cold. This also impacted the brightness level, some where very bright, other very less.
That's definitely a Samsung panel... Those hateful ****s. The depth of that trough at 100% is what causes the nastiest problems. Basically on this phone [11 Pro Max] you should never turn the brightness above 75% but optimally you'd run it at 50% at all times; The amplitude of that wave cycle shouldn't bother most people but who wants to run their device at 50%?
Besides, never buy a device that refreshes in the 240's... Learned that the hard way.
The hopeful part is that LG supplied 20M 6.1" iPhone 12 screens, whether that means regular or pro or both - I've no idea.

Question. My wife recently got her 12 pro and I attempted to film the panel in slo motion, the flicker did not seem as bad as my regular 12. Not sure if that’s indicative of anything, but just messing around with it for a few minutes it didn’t seem any better to use for myself without the white point adjustments. My question is moreso to do with the actual results of the “flicker” testing in slow motion, I have LED bulbs everyone in my house abd in these videos you can observe flickering everywhere, including outside of the phone panel (assuming due to the light bulbs). Would be happy to test both my 12 and the wife’s 12 pro out to see if there’s any information I can provide for the forum, but I’m just wondering how reliable any of it would be at this point.

I'm confused, maybe you can help me understand.
The Pro Max and Mini have yet to be released.
The Standard and Pro 6.1" have both been released.
Do you both have pro models, or does she have a regular and you have a pro?
Lol. Sorry. Early in the morning. She has a 12 pro and I have the regular.
Hmm. I'm ******** guessing here but given what you've said, I think we may be seeing the regular iPhone 12's sporting the Samsung 6.1 panel, with the PRO coming equipped with the LG 6.1". The display brightness is the differentiator in my mind.
I know that the problems get worse when you have a combination of flickering led and the iPhone display with PWM. Also for the purpose of slomo video, the best you can film this in a room without flickering led lights.
Lol. Sorry. Early in the morning. She has a 12 pro and I have the regular.
Could you try filming both if the screens at 50 percent brightness and see how it flickers and if it bothers your eyes?
I posted measurements from 11 pro and if I am correct 50 percent brightness should have least disturbing PWM.
Created an account just to share my experience with you all...
I had severe PWM issues with the iPhone X, XS and 11 Pro. I’ve bought each one and had to return it BUT the 12 Pro is completely different.
I’ve been using it since Friday very heavily and have zero issues with the screen. Right now it’s just passed midnight and I’ve been watching about two hours of YouTube and Netflix in a dark room and my eyes feel just as comfy as they did on my iPhone 8.
So in summary the 12 Pro Apple did do something different. It’s amazing I can finally appreciate the inky blacks and vibrancy of it all without those awful dry eyes, headache, blurred vision etc.

Just curious, what are your settings? True Tone, Brightness level, White Point, etc? I’ve had success with 50% brightness and 75% white point.
I am not using whitepoint at all and my brightness usually hovers between 30% and 75%. Completely fine with ~30% brightness in a dark room watching Hulu/Netflix for hours on the 12 Pro. Eyes completely the same as they were on my old SE, while on an X / XS they would be screaming.
Wow, that is great news- glad the 12 Pro is not bothering you!! It will be so interesting to see why this is, if the PWM frequency was increased, or if something else that we will never identify was changed this time around?
My experience this time around is not enough to base anything off of, but worth mentioning- my wife's XS Max does weird things to my eyes just glancing at it, and looking at it for a few minutes can give me eye pain.
But I was at a store on Sunday and looked at the 12 (not pro)- played with it for maybe 5 minutes, and had zero issues- it seemed easy on the eyes.
I am almost tempted from that and what I have heard from a couple people here, to throw my hat in the ring, to order the 12 Mini and see how it goes, holding onto my 11 until I know for sure if I will be keeping the mini or not just in case.
Regular 12, though now I’m wondering if the Pro is better on the PWM issue.
Wow, no issues at all from using it at low brightness in a dark room? That’s usually where PWM hurts the most.
My experience is the other way round. I have the 12 Pro and the normal 12. With the 12 Pro I had dry eyes after a short time and problems focusing. With the normal 12 I have zero issues. I’m gonna try another Pro.
Interesting! Strange there would be any difference, I would think they are the same displays this year.
All they had was a regular 12 in the store I went to on Sunday, but that display seemed very easy on the eyes for the 5 minutes I got to play with it- not the same experience I have when looking at my wife's XS Max. I wish I could have also seen a Pro to determine side by side if there was any difference!
I've posted in a few places including this thread that no, they're really not the same panel. For the 6.1" panels, LG is supply 20 Million units. I believe they are the Pro models as there is a distinct difference in brightness between the Standard iPhone and the Pro model.
LG Display to Supply 20 Million OLED Panels for 6.1-inch 'iPhone 12'

I personally think think this is central to the consideration of which are tolerable and which are problematic as LG and Samsung have very different backgrounds with the tech. Samsung is always, always, on the lowest end of the spectrum they can justify and LG has employed PWM free OLED panels in both TV and phone segments of their business.
Assuming Samsung is the issue with the OLED panels, wouldn't this be due to Apple's specifications they gave Samsung for the panels? I ask because many, many members have stated that they had zero issue with Android (often Samsung specific) phones even prior to DC Dimming yet they could not use the X, or XS for example. In that regard, it seems less that it is a Samsung issue in of itself, but instead the specifications Apple required Samsung to follow. The panels on the X, XS, 11 series, etc., while Samsung made, are not the same panels Samsung uses on their own devices which do not appear to be causing issues.I've posted in a few places including this thread that no, they're really not the same panel.

Samsung is, legitimately, the single worst offender in the low frequency pwm space. Across the board, their devices are almost literal cancer for the human eye.
See for yourself.
