PWM Frequency in OLED phones - Everything You Need to Know.. What You Can Do?

[@3lectronic0]

240Hz PWM on Galaxy S23 series destroys your eyes and causes migraine. The most expensive brands, Samsung, iPhone, Google pixels have the worst PWM. On the other hand, Chinese brands have 1920Hz, 2160Hz, that is unacceptable.

[@Tealtealr]

Exactly

[@ameserich]

Oled are quite slow compared to regular LED, meaning they cant flicker as much. Some laptop backlight can even flicker at 10khz The best option is to have DC dimming on 101 nits and up and to have 360-720hz PWM on 100 nits and lower. Brightess matters lower brightness PWM would definitely reduce eyestrain... going full DC is not an option as it result on very bad grey scale performance Big brands will probably never try going high 1920hz PWM because its inefficient, worse color and probably lower brightness

I tried an app called OLED saver, you choose and it keep the phone brightness at a higher level pushing the PWM to be higher then it applies a filter on top to control the brightness, honestly it was an improvement on my S22 Ultra. But the best solution is to get a Chinese flagship phone the PWM is insane and using OnePlus, Realme, Xiaomi phones never gave me any headaches or eye fatigue.

[@tomsbeingtheleo]

As for the first point I figured out putting the screen brightness to the max and using 'reduce white point' as I have an iPhone is kind of working, but it's a trip to activate! I wonder why apple also doesn'thave a separate toggle from the control center for activating Night Shift and the fact it cannot be permanently put on, smh... I'm definetly getting a flagship chinese phone in a few months, it's going to save my eyes from dryness and eye fatigues.

Only solution I found was to swap out the OLED with an LCD on a used iPhone 13 (or any iPhone.) Makes no sense to buy new if you’re going to remove OEM parts and replace them with third party parts. Outside of faster battery drain it’s been fine. I’d recommend buying the Plus variant to counteract the higher battery drain wish I would have done that.

@VYM, have you tried enabling the circadian display and setting the night sight to automatic display? I recently conducted a personal experiment, using the Samsung S24U for 15 days and the Honor Magics 6 Pro for another 15 days. Based on my observations, when using the Samsung device between 8:30 PM and 10:30 PM, I experienced difficulty falling asleep after turning it off. My eyes felt strained and dry, and it took me approximately two hours to finally get some rest. However, after switching to the Honor Magic 6 Pro, I noticed a significant improvement in my sleep quality. I was able to fall asleep within 15 to 30 minutes, and sometimes even while using the device itself. In my opinion, this particular device seems to have a positive impact on sleep compared to others. If you prefer not to use a smartphone, I would recommend considering their tablets as a secondary option.
