Severe Eye Strain due to OLED PWM Dimming

Hello , i have been using iphone for 10 years or so and with changes after iphone X which uses OLED , i am really unable to use my iphone due to PWM dimming which causes severe migraine and dizziness for me in 5mins. I have been stuck on iphone 11 due to LCD panels but i am worried whats going to happen in future since LCD is gone now. Can Apple implement DC dimming via software Update? i have tried 14 pro and it had same problems even though flicker has been reduced but doesnt help. I tried every accessibility option like reduce white point , keeping 100% brightness.

  1. I don't believe we're going to get DC dimming for OLED screens as updates.
  2. For those who don't understand what PWM is and how it affects a small groups of people, before asking them to go see an eye doctor, at least read a few articles about how PWM affects their eyes, and in some cases, dizziness and vertigo. Here is a start: https://www.notebookcheck.net/Why-Pulse-Width-Modulation-PWM-is-such-a-headache.270240.0.html
  3. Currently only iPhone SE 3 have LCD screens. The plain iPhone 11 is the last big display iPhone that have LCD and users who are affect by pwm can only use these 2 phones (that is if they can buy an iPhone 11 model). Note that iPhone 11 Pro & Pro Max uses OLED. And any thing from 12 onwards uses OLED.
  4. I am in the same boat as you because I am also affected by the pwm. If apple changes everything to OLED then I just have to say goodbye to iPhone. We are such a small group and I don't think they really care.

As a sufferer of PWM it took a lot of research to realise Apple doesn't care about PWM even though it really should be a great concern to their users eye health regardless of whether people suffer it. I use a company iPhone 14 Pro during the day and because it's not a lot I can use without suffering too much. I ended up buying the Motorola Razor 40 Ultra and don't suffer any PWM and you can also go to Huawei or Honor who both have very high refresh rates. If/when Apple address the issue I will return to Apple.

No one here in this user-to-user forum would know what Apple can or will do. However, you can let them know your concerns here:

Well as i said, it has nothing to do with Ophthalmologist , Why don't i have this problem while using iphone 11 or any other LCD phone , why just OLED. It has been proven that OLED causes migraines to sensitive users , same is the case with my samsung tv but if i watch in Movie mode which makes dimming @ 960hz frequency then there is no issue its perfectly fine , Manufacturers just need to use high freq PWM.

I am switching from an OLED phone to an LCD phone. The iPhone SE 3rd Generation released in 2022 has an LCD screen. This iPhone SE 3 phone is in the same group display at the Apple Store with the iPhone 15’s and iPhone 14’s.

I converted the data yesterday, I am pleased with the picture quality. The phone is small but has good clarity. It has rounded edges which remind me of the Galaxy phone I liked that I was converting from back to an iPhone.

Note worthy, I saw several posts where people said they were going back to their iPhone 11 because of getting headaches/migraines with the iPhone 14. Turns out the iPhone 11 is also an LCD phone.

Apple and Verizon have been very helpful while I was sorting this out.

This issue is super annoying and really affects me. I am someone that used to upgrade every year, but now I am stuck on the IPhone 8 Plus. I got the iPhone X, but couldn’t use it. I also got stuck on the iPad Pro 12.9 from 2018.

For those that suffer… these devices are fine for me: iPhone 8 Plus, iPad Pro 11 and 12.9 (both from 2018), and M2 MacBook Air. Some newer iPad Pro 11’s are okay, but that seems unpredictable. I really hope Apple start caring for people that have this as an issue. Lenovo have many TUV eyecare certified products, but Apple seem to be unaware. I have yet to find a ‘genius’ that knows what PWM is!

You can show people the PWM on the worst headache inducing devices by using an app like RAW+ photos and turning the shutter speed and ISO to maximum. It helps people that aren’t affected to understand what you are talking about.
