Other Eye-strain while using iPhone X and up

[iCantSee]

Actually, not sure if we are screwed. MicroLED probably will be fast enough that it won't be detected even by sensitive eyes.

The sub-nanosecond response time of µLED has a huge advantage over other display technologies for 3D/AR/VR displays since these devices need more images, more pixels per image, more frames per second and fast response.[2]

That is completely unrelated to controlling backlight brightness, which is where PWM is being used today.

Maybe someone updated to iOS 16.5?
Do you feel any changes?

 

[johnscully]

Very interested in that too.

The Apple Watch Ultra caused me eystrain. The series 8 has PWM according to notebookcheck. Has anyone had success with the SE or any other model?

Ok Guys,

I have been testing an iPhone 13 with an LCD screen for a couple of weeks now. The replacement procedure is fairly simple with the right tools, though I am a bit skeptical that the device will be waterproof afterwards. The only downside apart from this, is that obviously True tone dose not work and that the elements in the notification bar at the top of the screen are semi-cut (due to the faceid slot dimension? not sure).

TLDR: I am pretty sure that many with lower sensitivity than mine might be able to adjust and use. I could not.
But I cannot use iPhone 11 and SE either, so others might have better luck.

I have tried two screens:

First,

For iPhone 13 Screen Replacement for iPhone 13 LCD Screen Replacement A2633 LCD Display A2482 Touch Digitizer Assembly A2631 A2634 A2635: Amazon.de: Electronics & Photo

Second

Yodoit For iPhone 13 Screen Replacement Kit 6.1 Inch LCD Display 3D Touch Digitizer Glass Assembly with Repair Tool Kit: Amazon.de: Electronics & Photo

The first, an in-cell, had a visible glimmering when slow motioning it, I had dizziness and tiredeness and a light headache after hours of non stop usage. Definitely better that an oled screen (I would get eye sand and itching feeling and instant hard headache). It is also better than the latest macbook air I tried: after 1.5 h with the macbook I had to lay with my eyes closed.

The second one was a bit better, I could not detect any flickering in slowmotion. I would have liked to test it with the opple meter, but mine arrived dead (if you know a decent website where I could get it in europe, let me know please!! The second one was not an in-cell screen and had slimmer edges. I honestly could not really see a difference between the two.

Unfortunately, I could not use such screen either, but the symptoms were very very minor. Only a light dizziness. It's a pity that it did not work as battery life and photos were quite good.

The new Honor Phone oled display comes with 3840hz PWM

This is so interesting, indeed they talk about "zero-risk dimming eye protection screen from" https://weibo.com/1769228100/N1jIZvpf5?refer_flag=1001030103_ :

The new spokesperson Yang Yang was just announced yesterday, and today #Honor90 has revealed that it will be equipped with 3840Hz ultra-high-frequency PWM dimming technology, which is claimed to be a zero-risk dimming eye protection screen. The hazards of screen flicker may be difficult for us to notice on a daily basis, but now that young people are spending more time using screens every day, their eyes are prone to unknowingly become the most affected by the "light pollution" of mobile phone screens. With an epic PWM dimming frequency of 3840Hz, this zero-risk dimming screen puts an end to the danger of screen flicker, so you don't have to worry about the "vision killer" hiding in the dark anymore.

And from Digital Chat Station (https://weibo.com/6048569942/N1iyQn2Jc) talks too about "Zero Risk Dimming Eye Protection Screen"

Is there such a thing as 0 risk? Because if I remember correctly, from 3000hz PWM is supposed to be correct for the eyes, although it always depends on each person.

Well, whether what they say is true or not, I think that at least they are working on it and sooner or later it will reach other brands .

Yes I also read once that 3000hz and higher should be fine for our eyes

Have those of you who find the SE 2022 usable found that any particular version is better than others? I know there is some amount of display lottery with iPhones. I didn’t know if the SEs are all the same display supplier or if it varies.

My wife has the SE 2020 and I have the 2022. I can use both without any eye problems or headaches. Whereas the 13 mini caused me problems within a couple of minutes.

I haven't noticed any differences between models, but aside from PWM, I recommend 128 GB or larger for the faster storage speed.

Has anyone heard anything about the screen on the Honor Magic 5 Pro, just that I saw this in the GSMarena review of it.

Honor also improved the high-frequency PWM dimming system and boosted it to 2,160Hz (up from 1,920Hz). This should further improve the experience in sub-100nits brightness, and you should experience no ghosting.

Ugh. Bad news and good news. As someone who has bought multiple used 6s, 7 Plus, 8 Plus, 11, etc, I have two 7 Plus in front of me now and one has an absolutely zero irritation screen, while the other is a good bit higher. From researching, it seems like there's multiple panel makers for the 7 Plus with possibly a Sharp, LG, and Toshiba (didn't even know they made panels).

The good news is if I can find some app to query the hardware ID's of these things to pull up manufacturer information (they're jailbroken), then people will know which company actually makes good ones. Not sure if the good and bad panel makers of 2016 will still apply in the year 2023, though.

Here's pictures of what the good panel looks like (seems to have slightly better black level than other one and slightly darker gamma). From the moire-like effect in the 2nd picture someone might be able to guess what panel maker it is. Also have another used 8 Plus with original screen on the way. Only used one before and the first one had an ultra-saturated screen that was decent to look at but high eye irritation. Here's hoping the next 8 Plus has a different panel maker.

To be clear, you purchased a used iPhone 7 Plus? Isn't it likely that it was replaced with a non-OEM display at some point?

I've never actually seen a non-OEM Iphone screen that looks remotely similar to the original one. The original will be like 1400 contrast and the Chinese replacement will be 800, 1000, or whatever. Or the gamma curve and overall color calibration will be vastly different even if the contrast ratio is higher. I don't believe the 2nd unit is a non-OEM because the overall picture is so similar to the first. There are only very miniscule, hard to perceive differences. There are some vastly different specs of the units, though:

- Good unit is a US unlocked 7 Plus 128 GB with glossy black frame on latest IOS 15.7.6
- Unit with more annoying to look at screen is a Japanese, matte black, carrier locked 7 Plus 128 GB on 15.4.1

The Japanese government tends to favor domestic production and the US doesn't produce anything, so it's possible the two screens were made on entirely different continents or by different manufacturers. Like I said, I seem to recall reading there were screens made by Sharp, LG, and possibly Toshiba for the 7 Plus, but not sure overall.

LG used to make extremely good screens, as I picked up one of those "Korean IPS" panels that were being sold on Ebay years ago that were rebranded Apple Cinema Display 27" 1440p. Those used S-IPS LG panels (LM270wq1?) and they were very easy to look at, and the Ipad Air 1 is very easy to look at and uses a 1300ish contrast LG (IGZO?).

In terms of other devices, I find the New Nintendo 3ds XL models with IPS screens to be very bad to look at (sort of a PWM-like feeling), while the TN ones are extremely easy to look at. It's rumored that the IPS in those are Sharp panels, so as of now I'm kinda leaning towards LG most likely being the good panels in these older devices if multiple manufacturers are used.

After a few weeks with the 12 Pro I finally adjusted. I sent the 13 Pro and 14 Pro back within the return period when discomfort appeared. But with the 12 Pro which I got for 400€, I thought: screw it, I muscle through it and sell it when I see no chances to adjust - even after the return period since I can sell it with minimal loss.

Fast word - after a few weeks my discomfort is completely gone and I even think about PWM twice or thrice a day when I use it. A well built habit to check if I got any symthoms I think.
Its a great phone and I think I will keep it till 16 Pro or even 17 Pro.

So, dont let the return period set you under pressure.

I'm using a Google Pixel 7 Pro again after a long time. This causes me little or no complaints. Camera and performance are excellent. As always, only Android is the problem. But this time I'm trying to deal with it because I'm just glad to be able to use an up-to-date smartphone. I've also used the Honor Magic 5 Pro with no complaints, but the software was really creepy. I prefer the stock Android of the Google Pixel 7 Pro. Definitely a first-class smartphone, at a very good price. I privately paid €550 for the smartphone.

Interesting ... NotebookCheck says:

We determined OLED flickering in our measurements with the oscilloscope, but this is very constant at low brightness and is on par with the refresh rate at 120 Hz. As the display gets brighter, the frequency jumps to a stable 240 Hz. The effect is comparable to permanent DC dimming, which is why the likelihood of complaints is lower than with displays that have a choppier progression.

I've recently been reading a few people's positive experiences with the iPhone 14 range, and a blue light screen protector; additionally, I also came across someone on Reddit, talking about how OLED's blue light can exacerbate the situation for sensitive people:

https://www.reddit.com/r/PWM_Sensitive/comments/13eck7y

Add to that a current offer of $300 off on the 14 range, that I'm seeing around locally, and it makes me keen to give this a try ...

 

[PutinLivesMatter]

After a few weeks with the 12 Pro I finally adjusted.

There is no adjustment or break in period to PWM. Like I said earlier, people who only occasionally glance at a phone to check a stock ticker can use literally use any display no matter how bad it is. It takes a solid 10 minutes give or take before the absolute worst of the worst PWM laptops start to attack me badly.

This is why there's so much conflicting information in this thread - actually two reasons. Number one, people look at the phone for 1 hour then say it's a torture device then post again in this thread the next day after only looking at it for 5 minutes in a row and then say the screen is perfectly fine.

The second reason is it takes around 10 minutes or so for a 200hz PWM laptop to really start bringing the pain, while these devices with higher PWM like 480 take longer and sneak up on you in a more subtle manner. So instead of 10 minutes before it feels like a team of Lilliputians are attacking your eyes and head, you get both less severe symptoms and a longer amount of time before it happens, but IT'S STILL THERE.

The main people who are easily going to notice this stuff are people who do things like read text for a long duration on these devices because your relaxing activity starts to feel like Chinese water torture. Very few of these devices are suitable for this activity at all. Out of all the tablets and phones I've used, the Ipad Air 1 from 2013 is basically the gold standard for zero eye strain or weird discomfort while reading and everything else is on a scale below it somewhere (some of the other non-pro, non-laminated ipads are similar to it but their contrast ratio is lower).

Won't help a single bit. The only thing you can change on a PWM iphone to help eye strain is set screen brightness to max then use the "reduce white point" slider to lower white level, thus making that slider your new brightness slider. This obviously has some cons to it but better than nothing I suppose.

I have an Iphone 11 and 13 in the house and even though the 11 (LCD - no PWM) is worse to look at side effect-wise than older screens like the 7 Plus, it's still better to look at than the 13. You can still buy 11's brand new on Ebay and all over the place, and the 11 is still insanely fast, so no reason to use a PWM phone at all (I would consider the 7 or 8 Plus as well).

 

[PutinLivesMatter]

Screen comparison - US 7 Plus on left, Japanese 7 Plus middle, 8 Plus on right. All calibrated to similar white point and brightness levels.

Really strange that I’m reading this because for quite a few weeks now I’ve experienced a bit of head pressure between the eyes, like around my sinus, then can be in the head too.

However, it only happens after using my M2 Air and more rarely; my iPhone 14 Plus.

I went away on holiday and had no exposure to screens. Guess what? Zero problems.

I go to the pub or play tennis and guess what? No issues.

I’ve never had anything like this in my life so I’ve been very worried, to be honest. Did see a doctor.

Will go to the opticians but it does seem coincidental that I got my M2 Air late last year.
