LCD Phone Huge discovery (imo)

0 Upvotes

So I just made a huge discovery in my opinion. A phone I have been using for social media, youtube and chatting at home for few years now is Nokia 6. It has an IPS LCD panel. To this day I had no idea it uses PWM, but I got curious about is's display so I googled it, just to figure out why the screen is comfortable for me and what to look for when choosing a newer phone. To my suprise it shocked me that the phone uses PWM at 2381Hz below 17% brightness. And I am using this phone at a very low brightness (5-10%) all the time so I would feel it, if it bothered me. But that is not the weirdest part. The moment I discovered this, my eyes snapped and started feeling slight discomfort. Same thing I felt when I tested other newer phones. This would mean it is a purely mental/psychosomatic thing. I am not saying PWM sensitivity is not real. The whole flicker thing is bs and devices just should not do that ever, but some users might be in the same boat as I am. I wanted to find therapyst for a while becuase of how my life is but I have been putting it off. I guess it's time to work on my mental side. I will keep testing the phone tho. If you have any questions ask away, I am very active here. Edit: I might have said something wrong, english is not my first language. By saying flicker is bs, I meant it shouls not be used in any device and some other form of screen dimmomg should be used instead. I absolutely think PWM sensitivity is real for a lot of people. It might just not be the reason of pain and discomfort for everybody. Hope this clears thing out

Any non Chinese phones?

Is resorting to further funding a country that wants to crush the west with the profits the only option? I know avoiding funding the Chinese regime is too difficult at this point, but can I least not be seen going around sporting a Chinese brand?

iPhone clearly worsens the condition of your face

0 Upvotes

I started noticing that people with iPhones most often have a bad facial condition, they have a tired facial expression or a lot of acne. Just look at people on the street who have an iPhone. People with better facial condition were more often either using older iPhone versions (iPhone 11 and below, IPS screen) or Androids, presumably also with IPS. It may sound like nonsense, but just check it yourself. If you don’t live somewhere like the US, where basically everyone has an iPhone, and instead you’re in Europe, where many people actually use Android, you’ll notice it

My theory is that the OLED screen of iPhones emits too intense light and it clearly somehow affects the skin. Even I, when I used my iPhone before all the settings like double inversion, filters, and others it literally burned my facial skin. I felt tingling, and I developed seborrheic dermatitis. As I later found out, it occurs when the composition of skin oil changes. What else could have changed it except the super intense light emitted by the iPhone?

Basically, my skin started to turn red and peel near my nose, and my eyebrows started flaking.

My condition was terrible. After literally a couple of minutes of using it, I felt absolutely drained, like my soul was taken out of me. After putting the phone away, I could stare at one point for a long time without any thoughts, like my nervous system just burned out. After googling, I realized that this is a protective mechanism of the psyche when it just shuts down under overload.

There is also a second theory. It is that either because of PWM implementation or a d word, the nervous system cannot relax. These black lines load it, it doesn’t feel calm, and maybe this reflects on the face making a person look tired, their skin ages, acne appears. These are all well-known symptoms of how stress affects a person, and if it works here too, then the iPhone causes stress for our nervous system.

An IPS screen, on the other hand, does not load the nervous system, so people who have it will look better than those who have OLED. This is biology.

I bought an iPhone 13 new from the store, assembled in 2024. At that time I didn’t know terms like OLED, IPS, PWM, d word and all that. I didn’t even know what kind of discomfort people can tolerate just using Apple devices. There was zero information about this on social media. The iPhone had an image of being a completely safe phone. Later I also found out that iPhone 13 units produced after 2021, meaning from 2022 and later, are much worse than those from 2021. I got exactly such a bad unit, but I didn’t know anything at all about this, nobody said anything about it.

Turn on reduce white point to use and control brightness. I posted this maybe two years ago and it gets buried under the noise and ignorance here.

Dc dimming on iPhone

2 Upvotes

New iPhones are literally not using PWM for brightness adjustment when the checkbox is checked.

PWM-based dimming works by turning the screen (or parts of it) off. The longer it stays off, the darker the screen looks. And when the off-time is equal to or shorter than the on-time, PWM becomes very noticeable.

Old iPhones at 50–100% brightness and new ones with the checkbox enabled at any brightness don’t make the dark lines wider (don’t increase the time the screen is off). This means they use DC dimming.

It’s literally not PulseWidthModulation based brightness adjustment, because the width of the pulse does not change at different brightness levels!

But the problem is that the lines are still visible at every brightness level. So the PWM brightness issue is actually solved. The question is: why are the lines there at every brightness level? Are these lines related to screen refresh?

Retina display causes eye strain and short term blurry vision

0 Upvotes

We all know Apple uses a retina display (which uses 4 pixels as 1 to show things to make them look smoother) which makes images look smoother but for text, it makes them look slightly bolder. This has the side-effect of messing with carefully designed character shapes produced by font creators and makes the text more blurry to the naked eye (at least for me and many others who have mentioned this on Reddit)

I'll make this short, I'm leaving a link that has an image that allows you to see what text on your Mac would look like without font smoothing. Download if you need to, I just wanted to spread this info

Discussion I think I now surely know why phone companies won't switch to LCD ever.

1 Upvotes

Basically, it's because it's a net loss for the company. Oleds have more colors, 'deep blacks', physically take up less space (which allows phone companies to fit more components in a phone with an oled vs an lcd), use less power (more battery life, very important), and can get brighter with less power due to their low power requirements. In fact, new oleds can reach 2000nits of brightness, while the most modern phone LCDs only hit about 600-700. Just for reference, a Large TV is about 4000-6000nits. This heavily contributes to pwm sensitivity problems.

But do you wanna know the very last reason that companies won't switch? Money. Phone companies can't improve LCDs much more, whereas oleds are still new and evolving. Also, oleds cost more to get, therefore causing phone companies to charge even more.

TLDR: money

Discussion The real problem with OLED screens: uneven dynamic lighting.

15 Upvotes
  1. OLED’s self-emissive nature causes light to shine directly into the eyes, and the uneven brightness of individual pixels can worsen astigmatism.

  2. LCD pixels themselves do not emit light; instead, they rely on a uniformly distributed backlight, so the brightness remains consistent without the noticeable fluctuations seen in OLEDs.

  3. The pixel light from OLED screens shines directly into the eyes, which can directly lead to worsened astigmatism, double vision, headaches, and pain around the eye sockets.

  4. stop wasting time and money worrying about PWM frequency—no matter how high the Hz, OLED will inevitably worsen astigmatism.

Question Monitor sold as flicker-free but look at that...

0 Upvotes

Frankly, I don't have the impression that it is, although on the Dell website they state that the screen is flicker free and TUV certified... The first screen is the Dell G2724D in 165hz and the second a philips 245E in 75hz... The Philips looks really good flicker free whereas the Dell doesn't seem to be... It scares the hell out of me because I'm very sensitive and I already feel a little discomfort (but maybe it's placebo because I'm thinking about it...).

Help ! :'(

Dc Dimming vs PWM

0 Upvotes

Ok. So I asked ChatGpt and he says Dc Dimming is better for the eyes. It causes less strain and fatigue.

But anyone can confirm this?

Anyone has tested a CellPhone with Dc Dimming and one with PWM and has experimented this and can confirm if it is true?

I do not know if I should buy an iPhone 17 (has simulated Dc Dimming) or a Xiaomi 15 (has Real Dc Dimming).

Wich one you think it causes less fatigue and eye strain?

Thanks.

Has anyone in this forum sued Apple? pwm really hurts

15 Upvotes

Has anyone in this forum sued Apple? Since the iPhone 11 Pro, Apple has been providing low - frequency PWM dimming. When the iPhone 17 was released, it was said that there was an option to reduce this low - frequency dimming, but in fact it did not work. This involves consumer fraud and harm to consumers' health. And they are still cheating to us

LED Light Flicker Meter- terrifying result on 14 pro max

0 Upvotes

Trying the iOS “Flicker meter” app on 14 pro max screen as last two days having headache. Flickering on 80% reduce white light is terrifying to me. Further, the rolling bars of light- right to left is not visible to my eye but another phone’s camera caught it.

Apart from PWM flickering on OLED screen, what was that?

How bad it would be for my eyes as already sensitive to PWM? Thanks in advance.

Eye Strain Symptoms iPhone 15 Pro - Eyeball pain - PWM or 5G?

0 Upvotes

I've used a OnePlus 8T 5G and Pixel 7 before, and I'm currently on an iPhone XR. I was already aware of PWM , but thankfully none of these devices gave me any symptoms. I assumed I was in the majority without symptoms.

About a week ago, I purchased the iPhone 15Pro and tested it for 2-3 days before adding an eSIM. I didn't notice any issues then either.

I just realized today that right after installing the eSIM I started noticing my eyes starting to hurt - the eyeballs specifically, and the eyelids would twitch for a long time after I stopped using it, and my eyes burnt as well.

So, I decided that the iPhone15Pro isn't for me and deleted the eSIM, getting it ready for the return.

For some reason, I didn't reset the device yet, so I used it to browse and read something as my XR wasn't close by. No symptoms. NOTHING.

Curious, I scrolled and browsed for easily an hour reading random stuff just to "test" this device. I find it really strange that I still have no symptoms.

What's going on here? Am I sensitive to PWM or is there something in the new iPhone's 5G radio that's giving me these symptoms? It is really bizarre.

EDIT: Unfortunately MINT mobile only gives me 2 free eSIMs per year and the lack of a pSIM slot makes it really less-simple to test this back and forth between phones.

EDIT2:
The Pixel 7 used the Samsung Exynos 5300 5G modem

The OnePlus8T 5G used the Qualcomm X55 modem

The iPhone 15 Pro uses the Qualcomm X70 modem

Discussion How to Mitigate Health & Safety Risks from LED Lighting – Flicker Alliance

Thumbnail flickeralliance.org
0 Upvotes

High brightness hurts eyes more, on consumer displays, only if pwm is held constant at every brightness setting. Holding pwm constant, increasing brightness increases modulation percentage which increases the jarring effects of strobing a bright light.

However, if pwm frequency increases as brightness increases then it can decrease the perception of strobing to offset the increased modulation percentage.

I might be preaching to the chior, but I just want to point it out.

Better tests needed for PWM

0 Upvotes

We need to talk about more appropriate tests to detect whether there is some dc dimming.

ultimately we need to see actual brightness intensity decrease.

the logic is that you flash the screen at the same brightness intensity at a certain frequency and adjust the flash duration.

now in theory if you have at least SOME dc dimming you can afford to either increase the the frequency of the pulse OR you can increase the flash duration; to mimic what the pwm would normally have been.

so we need a device that can detect intensity of light such as a photodiode which can measure high frequencies.

for now visually, on videos we should at least see faster frequency, or smaller pulse width, or both.

But until we directly measure the brightness, we wont know to what extent, if any, dc dimming has been implemented.
