I find it interesting that the comparable charts for iPhone 14 Plus appear to match the 100% DC dimming of this OLED laptop panel, whereas the lower-brightness 240Hz PWM more closely resembles iPhone 14 Pro Max:
This makes me skeptical whenever they mention DC dimming and the curves appear like PWM.

Here is one that is made of glass and there’s a gloss and a matte version. I have absolutely no experience with it but I saw some guy doing a video on it on YouTube

Edit: I think that particular one might be for the 14 pro but they might have other models to fit other phones
Glad you are liking it! its been a revelation for me, and at the price I paid i feel pretty good about using it for the next couple of years compared to paying 2 or 3 times the price for a brain scrambler.
I really cant say enough about this screen. Maybe its the color calibration, maybe i won the screen lottery. All i know is im continually pleased with it, the one handedness, and the return to the home button. I do actually like the gesture based OS quite a bit - but there is just something inherently natural and pleasing about that good old button.
Congrats on making a sound financial decision, and finding a device you can use and enjoy.
It's funny how our muscle memory works. Jumping between my 2017 iPad Pro, iPhone XR and Mini 6, they all feel totally natural and I don't even think about the fact they are all different in how they authenticate. Of them, I think I still prefer the home button nav of 2017 IPP. There's just something about it that feels really natural, as you said. Perhaps all those years of home button navigation are just permanently wired up in my brain as "the way", haha. I also very much enjoy the gesture nav as well, but home button will always feel like... well... home.
I’m not quite sure why this is, but I reset my brightness shortcut to 38% and I think I’m getting a slightly better experience from iPhone 14 Pro Max when the rate is 240Hz surprisingly enough despite all of my literal headaches with iPhone X and iPhone 12 Pro Max.
I guess the morale of the story is that consistency in the rate is crucial, as raising the brightness to attain a purported 480Hz rate isn’t a miracle cure. Then again neither is 14,880Hz on a Mini LED display.

Happy to hear people are pleased with their 2022 SEs 
I really loved mine for the time that I tried it out, but just couldn't escape the boxy throes of my 13 mini and ended up returning it 😫
Interestingly enough I do remember battery life and cell reception being way better on the SE, and the display was of course a real treat to my eyes.

Truth be told iPhone SE has a much more comfortable display, and I’ve been taking the quality fore-granted.Happy to hear people are pleased with their 2022 SEs

Apple did a really great job calibrating the colors, as the 2022 iPhone SE has perhaps the best LCD display I’ve seen on any Apple product.
It’s stunning, I absolutely agree. The colors really pop, even compared to (overrated) iPhone OLED displays.
I have the SE2. I have not tried the SE3. Are there improvements besides the new chip and modem? Is the display better?
Maybe a bit better-tuned, but probably nothing major you’d notice in the day-to-day would be my guess. Only way to find out is to try one out for yourself
The biggest difference beyond the obvious changes is that the build quality feels noticeably improved. I’d say it was worth the upgrade for that alone, while I also find the display calibration to be slightly better even if the contrast on the SE2 is already class-leading for a LCD.
Has anyone had any success in troubleshooting or escalating this with Apple’s accessibility department? I spoke to them once or twice and their advice was to just try accessibility settings to see if they helped. It’s hard for me to believe that they have a whole support department that exists to just tell people to try those settings? Do they not have more specific advice or troubleshooting steps?
Trouble is, if your sensitive to OLED PWM and/or dithering there aren't any real settings in accessibility to help mitigate this as the hardware and software is working as intended/designed.
It's our sensitivity that's the problem, this is partly why I think Apple have kept LCD options in the lineup up of products.

It's like the conversation I've had with my site manager at my office. I've explained that the new ceiling lights that were installed are far too bright and straining my eyes which leads to fatigue. They are LCD panels as bright as daylight.
Having filmed the lights in slow-mo I can see they are flickering like crazy. Every surface in the room is being washed with flickering light! When I show the video and explain about PWM etc I get looked at like I'm a little crazy with comments "but they aren't flickering" and "they don't cause anyone else issues" but was told it would be looked into.
I pulled a light unit out of the ceiling to look at the controller and Google the model to find it has a cheap, low frequency PWM controller onboard. The site manager came back to me to say the installers are certain they have good PWM controllers so there is nothing to address - so they lights are bought, installed and working as designed. The only compromise made was to reduce the amount of light units in my office space to make it less intense. This hasn't really solved anything but this is the way the lights are and I'm the problem (my eyes/brain are the problem)!
To help myself I've setup two down lamps with wire filament bulbs either side of my monitor to wash my desk area with warm and non flickering light to help my eyes as I stare at a screen all day working on graphics. I also setup a visor on top of my screen to block seeing a panel across the room from me.

Not too low though.....
"The iPhone's ProMotion display also shows the flickering that is typical of OLEDs, but a quite smooth curve with a stable 240 Hz at minimum display brightness. If this is raised above 39 percent, the frequency then rises to a constant 480 Hz, which is comparable to high-frequency DC dimming. The burden for sensitive people should thus be lower. No temporal dithering was determined, which we checked for by examining the display with a microscope and a 240 FPS slow motion video (dark gray, at full brightness)."
Things to try that might help:
Reduce motion in accessibility
True Tone on or off
Change the white point in filters
Turn off "attention aware" for face ID.
Yeah I guess except they put so much effort into all of these other relatively obscure issues that they have accessibility settings that are designed to address. It seems like something that one could address in some sort of setting. In my experience the difference in software version can make the same piece of hardware cause eye strain vs not cause eye strain. Sure there may be trade-offs with respect to color accuracy or power management or whatever. But I’m sure that’s the case with any of these accessibility settings that change how the display looks or works. I mean does anyone think that color filters or invert colors or whatever has a positive effect on color accuracy? I’m sure changing the default contrast levels has an effect on battery life also.
The other thing is I’m sure it’s a spectrum of sensitivity to flicker or whatever is causing this issue. However it’s amazing to me that I can literally stare into car headlights and other displays they have a lot of visible flicker when filmed in slow motion yet they don’t cause me any issues. Somehow the OLED phone screens or I guess in some cases LCDs being driven a certain way cause the issue 100% of the time very quickly. I had Apple support file a feedback ticket twice over the past few years on this. Maybe it will eventually get sometime to look at this. Anyways, I guess I’m just frustrated.
I really don't think Apple, Samsung and LG want to talk about PWM and the potential issues their products may be causing people. To create accessibility settings to help with PWM would be revealing an issue.
i absolutely share your frustration, as i am sure many others do as well. I can seemingly use my laptop/monitor at work without much issue, yet when I film it, it certainly flickers.
But 5 min in a low light setting with an OLED iphone and look out!
I have been trying to figure this out since i had to return my awesome 11pro, and since then the high end models just don't even get picked up on the radar. I would love to be able to consider pros and pro max's and minis - but I cannot.
Is it astigmatism based? ADHD? some other optical or neurological condition yet diagnosed? Or is it something diagnosable at all?
I am certainly grateful that I can at least use the IPS displays without issue, some aren't even that lucky.

Yeah I don’t know when this first started happening I went to a neurologist who did a pretty extensive work up. I had an MRI on a high resolution machine which was totally negative and I even had a six hour EEG test where they use flickering lights to try and induce a seizure. That was negative also. I do get migraines sometimes but they’re usually triggered by food or environmental allergens. I’ve never once had any sort of lighting or screens trigger a migraine but I guess it’s possible that this specific type of new screen is an exception. It just sucks because so many things are dependent on smart phones.

At this point the solution will probably come quietly built into a future generation. Although iPhone 14 sounds like it has the potential for mild symptoms.
As I usually do but tell myself I won’t, I’ve found that the 240Hz frequency on iPhone 14 Pro Max may be better than the 480Hz frequency and that brightness shortcuts make a difference for the first time ever. 3% at night and 38% during the day works decently.
Doesn’t low brightness make things worse for those that are sensitive to pwm?
The frequency is 240Hz at lower brightness levels which shouldn’t be better, but I seem to be having a better experience.
The amplitude at extremely low brightness levels is relatively low, as the max brightness of the panel is 2000 nits thus PWM has to be implemented intelligently.
That’s really promising news!
I have a 13 pro that has mildly affected me over the last year… I’ve kept brightness at about 85% and reduce white point to 95% and it’s been ok, but sometimes gives me eye strain or a headache- especially if using it for a while in a darker room.
I always assumed the higher brightness was best… as I turn it down near 50%, I notice more symptoms. I should try it even lower than that for a longer time to see how it goes.
