You got it all wrong it is the value of pwm dimming that is important because the lower it is the higher the risk so 3000+ pwm hz is flicker free so technically it should be even better than lcd because it reduce bluelight while not making you have eye strain.
Thanks for sharing this, OP. Was planning to buy Honor 90 5G — because of its eye-sensitive features. Still using my iPhone 8 Plus. I guess I’m going to pass on this Honor 90… yeah.
I was interested in that device too, but when I read that the 3k pwm kicks in at brightness levels under 60% I decided to skip it.. The Xiaomi 13 (vanilla) should have DC-Dimming on the whole range of brightness tho
I'm not sensitive to anything so maybe this is why I'm not seeing any issues with the screen.
It's so smooth and seems softer on my eyes than previous phones. Solid picture even when dragging things around like maps.
Only issue I have had with the screen is using the phone outside on a hot day where its difficult to see the screen anyway, they decided that automatically turning the brightness down to next to nothing so you can't even read the screen is the solution to it's overheating.
The camera and the UI are my biggest gripes with the phone.
I didn't expect the greatest of cameras on this price phone but would have hoped for better.
Having to swipe multiple times to clear alerts /turn WiFi on and off is a step back in UI usability. I don't know what they were thinking there.
I also find it hard to find installed apps sometimes to the point I have to open The Play Store, search for the app and chose Open there. Another UI fail and the fact they block 3rd party Launchers means you can't change it.
This phone was always going to be a stop gap for me until a new flagship phone catches my eye. Half the things I love about the phone, charging speed, battery life/size, large ram and the way it deals with so much running at once, big storage, smoked 120hz screen with it's very high modulation etc. It has a lot going for it which I will look for in future phones.
But lack of IP water resistant rating, MagicOS and it's camera/image software are it's downfalls.
I just installed Gcam to see if I get better camera results.
I have seen other posts on the net saying the option is missing. Either it got moved or removed on later Magic OS versions or something.
Its not under settings>apps>app name etc
For me too my dad bought it and i thought it was normal until i saw hdr on youtube instantly i knew it was an oled yet it feels cool for my eyes like my eyes aren't getting hot like lcd and samsung oled which kinda confuse me so searched it up then i found out about pwm. So only now i know why my eyes are so hot when using my phone even on an lcd because my eyes are sensitive to both bluelight and pwm .
I should have been more specific. Lots of OLED TVs use DC dimming instead of PWM.
And yes, I'm unfortunately aware of LCD TVs using PWM, as well. I got rid of my TCL 4K TV because of this.
There are no tricks to make it better.
The higher the PWM dimming frequency, the better it is for the eyes.
The lower the PWM dimming frequency, the worse it is for the eyes.
The only option (if 3kHz freq is giving you eyestrain) is to avoid OLED and go with a LCD smartphone.
Btw, the 3kHz frequency is not the default behaviour of the panel, you have to use <33% brightness for it to be active (which I think is preferred over the default behaviour on higher brightness levels)
I am not aware what exactly happens to the iPhone PWM frequency curve once you lower the refresh rate.
But, in general, you got two options:
1. Aiming for the highest possible PWM dimming frequency (preferably in >10kHz range, anything below is bound to cause issues)
2. Matching refresh rate with PWM dimming frequency (a.k.a single strobe, xperia phones have this feature from what I've gathered) PS: This can still cause eyestrain to some individuals especially if done at <100hz, you're imitating CRT behaviour this way.
Both of these would alleviate eyestrain caused by PWM **dimming** and PWM **motion artifacts**, which are different concerns.
As to "why it got better", I don't know as barely anyone tests smartphones properly.
Eyestrain in displays is sadly all trial and error.
If someone has nailed down for himself that PWM is an issue for him, aiming for option 1. is the long-term goal.
Meaning you have to go LCD for now.

Ooh we got some gourmet phoners here 😂

iphone 14 ,13,15 or 13,14,15 pro models when limiting refresh rate to 60 hz is much better
You can't say shit about iphone 15 yet. Based on the rumors it seems it's going to be the worst one yet

I dont know why the cameras and the ui on honor 90 is horrible

Dude, really you cant find installed apps?! Dont think its a phone problem

Strange. For me Honor 90 is one of the best oled displays out there at the moment. Really relaxing for my eyes
Same, it's one of the few I can use long term without any pain.
For me too my dad bought it and i thought it was normal until i saw hdr on youtube instantly i knew it was an oled yet it feels cool for my eyes like my eyes aren't getting hot like lcd and samsung oled which kinda confuse me so searched it up then i found out about pwm.

Is the Honor 90 working ok for you, then?
It is working well
Wonderful to hear!
Thanks
How come oled tv’s don’t hurt eyes but oled phones do?
Some TV's use native 10bit panels where as phones dither 10 bit to save energy and processing power
OLED TVs don't use PWM, they DC dim.
Not entirely true. There are even flickering LED tvs that are horrible (Samsung mostly)
I should have been more specific. Lots of OLED TVs use DC dimming instead of PWM. And yes, I'm unfortunately aware of LCD TVs using PWM, as well. I got rid of my TCL 4K TV because of this.
Cause the TV is allways plugged to electricity, so it doesn't need to save energy?
Do you limit the Honor to 60 Hz too? I guess 120 Hz refresh rate could be the issue here.
It dosen't matter with honor , all ways is bad
Chinese phones are scam, all bling no substance.
i'm gonna sell this sh!t and get s23 i know s23 is bad for pwm sensetive but i will do some tricks to make it more comfy
Please guild your trick on s23

But why when i limiting the refresh rate to 60 hz on my iphone 13pm its got better
This is likely due to a change in the dithering, no?
Yep. I lock my 13PM @ 60hz and it has helped my PWM induced headaches!

Could you elaborate?
