PWM sensitivity causing eye strain in AMOLED Smartphone

[twinbaby]

anyone experienced eye strain/migraine/insomnia after using AMOLED smartphone? this topic is commonly discussed in ledstrain.org and Reddit but I realised many people are not aware of this issue. LCD smartphone is better for the eye because there is close to no flickering and whereas AMOLED when you view the screen on camera there is black lines across it. another way to tackle this issue is to use dark mode and eye comfort reduction mode.

for me i set the eye comfort shield to low level (so that screen won't turn yellowish yet with some protection), and set dark mode

PWM dimming frequencies:
Galaxy S23 Ultra – 240Hz
Apple iPhone 14 Pro – 480Hz.


Most china phone (Vivo, Oppo, Xiaomi, Huawei, Honor) have PWM dimming frequently at least 1440Hz.

In Short
PWM is a technique used in phone displays to control brightness.
This tech plays a crucial role in addressing screen flicker sensitivity concerns.
Low PWM Dimming support on phones develop headaches or eye strain.

Hi ,
So you mean China Hps are better for the eyes?

I am considering China brands Hps if upgrading.

So far no issues ,
But for long hrs usage, use dim mode, set minimum screen brightness. Not sure if it helps...but can put on Anti-BlueLight specs while viewing.

I do hear a lot of middle aged users turned 老花眼 complaining due to prolonged looking at HP screen.

Insomnia no...not true . I always sleep within 5 mins even after staring at screens for hours beforehand

the problem about setting minimum brightness is that PWM screen will induce flickering. it's common and very well researched.

for me, a fast internet and fast phone- cause I get quite irritated when phone run slowly. and also, set my browser to dark mode.

blue light all these are gimmick

I have less eye strain after using S23U, more eye strain using xiaomi phone.. apple one also quite comfortable to my eyes..

 

[Phen8210]

is it cheap phone eyesore

maybe? S23U and iPhone i can stare at it all day, no headache no eye discomfort..

My old xiaomi phone I had a problem since day 1 using the screen, and it all went away after I changed phone

Best is to use LCD phones
Except for honor X9 ,I realized the rest of the LCD phones do not support super fast charging
Plus the fingerprint scanner is always by the side instead of on the display

I felt that the best LCD phone that is an all rounder is Huawei mate 20 though I am still using redmagic 8 pro due to the super fast charging
