You always write that LCD flickers at 30hz. I don't know how many hz the iPhone or iPad screen has, but any normal LCD panel is at least 50hz/60hz some are even 100hz or 200hz, so if it flickers at 30hz but the panel is 60hz there shouldn't be any flickering then.
In this article they write the iPhone display is 60hz.

So again, your article says a LCD flickers at 30hz, but iPhone seems to be 60hz. Then why should it flicker at 60hz?

If you are looking for it, you can find it, playing with test images, colors and brightness ...
The problem during normal use is not flickering. It's the pixel walk/inversion/whatever you want to call it. 99.9% of people would never notice it (or think anything of it) so I don't think this will ever be a widespread "problem" for Apple, but for those that do notice it, it can be an annoyance, especially if your previous phone didn't do it.
There are screens out there that have it and those that don't, and the degree of severity varies between them. Mine & my fiancé's have it, but both my parents' don't.
But again, the VAST majority of users will never see it (and if they did they wouldn't think of it as out of the ordinary). I'm one of the ones that do but I'm not returning the phone over it.

Thank you! I tried to tell Max(IT) so many times that the problem during normal use isn't flickering but these lines (I call them lines, but it's the same thing you refer to), but I'm still not sure he read it carefully enough. I also agree that most people don't see them by themself, but they see them after showing them what to look at. So if it is considered a problem or not depends on the person (like it did with the scratches etc on the iPhone 5 for example, some people swaped it because of that, most didn't probably even care). But the "problem" is widespread. The people who can see it, can see it on almost every phone. You can also call it "effect" for example, then the "effect" is widespread if you like that word better than "problem".

Please still explain me why an LCD flickers at 60hz. You insisted that much that every LCD always flickers but your article only says it flickers at 30hz. I don't know any screen that normally runs at 30hz (only Blu-Rays at 24hz). Every LCD computer screen (and as it seems also the iPhone) I know runs at 60hz. Since I never ever saw any flickering on these screens I'm really interested in your explanation now.

You are confusing refresh rate (the number of times an image is depicted on the screen every second, called display drawing on that article) with the polarity inversion applied on every pixel.
Btw it's useless to continue on this discussion ... 30 Hz, 60 Hz or even 100 Hz LCD displays flicker because they are designed to do that. Whatever this is something that bother you or not is the point, but it's not an "issue".
The Problem 100% exist! I can see it easy without the testpic too. Have to sawap countless times to get a perfect iPhone unit.
My expierience here in Germany is that it has nothing to do with the serial number or factory the phone made in. I had C3, DN, and F2 units the problem was on all present. My flawless unit i own now is a F2 and its really Perfect, thank god...
There is really a QC issue going on ob apple products these days... But at least they are very helpfull and have excellent support! I swapped 13 brandnew sealed units to get my perfect one, i hope i never ever have to do this odysee again. But i wanted that what i payed 900€ for!

That still isn't any explanation. CRT needed like 85hz to be without always visible flickering. LCD can run at 60hz because there is no flickering (or not visible) at 60hz. Why would every computer screen be 60hz if there was flickering visible? I really would like to hear your explanation and not just some "they are designed to do that".

I don't he knows the difference between flickering and Pixel inversion.
Again ... You are speaking about refresh rate ... Please read that article is quite well explained what polarity inversion is and how interleaving doesn't work very well in inversion test images.
Ps: CRT was a totally different technology where images were designed on the screen I'm a different way.
iPhone 5/5s Display Interlacing: New Image
Even if it's refresh rate, a screen at 60hz refresh rate doesnt flicker. At least there is nothing visible to the human eye. iPhone flickers like hell with the test image, so for sure its not a normal LCD behavior.
About the other "nice" words you recieved. I dont agree with all the words he used, but bascially i agree with his statement. I honestly tried to explain it to you over and over again. The thing is you really are just trolling around, telling people what they see is wrong etc. without even exactely knowing what we were talking about. You dont have the issue on your iPhone? Great for you, so there is absolutely no reason for you to post in this topic anymore. You being here to continue telling people they are basically lying is just trolling around. I really hope you get yourself a new hobby soon. And honestly the thing about you being a pilot i kind of doubt too since you do behave like a child, I just never mentioned it since it doesn't matter in this forum/topic.

This post show me how you didn't read the article so it's useless to continue the discussion with you .... Every display flickers, more or less, with that kind of test images (there are many).
The refresh rate doesn't matter in this case ...
What do you believe or not about me I don't care at all ... and if 83 is your year of birth, well, I'm much older than you ... Much ...

Yes it is pointless since you actually cant explain it. But if you honestly continue saying you can see flickering on every LCD screen Im really really glad i dont have your oh so perfect super vision...
Well no, I dont believe you, but you are right, it doesnt matter. If you are really as old as you say then please do me the favor and start acting like an adult and not like a childish troll. You gave us your opinion about this topic, we all read it, so there honestly is no reason for you to continue writing here since you are not affected by the problem of this topic. An adult would realize this and move on.

/me backs away from thread.
My iPhone is fine. Don't want to look for problems and become paranoid, haha.

I don't have any flickering on my gold 5S. My serial is F2ML if that means anything to anyone.
I did have a black 5 from launch day that was giving me a headache, that lead me to find the original flicker thread with research.
i guess i got lucky this time around

I like thread like this on MR forum ...
A lot of people without problem in real usage who is desperately looking for a problem in a test that nothing has to do with normal usage.
Who said it had anything to do with normal usage? I actually said I never noticed it in normal usage, so it doesn't pose a problem for me.
iPhone 5/5s Display Interlacing: New Image
I was actuallu afraid of interlacing issue, i tried every test image running it on my 5s, an f1. I looked for lines on my screen even with my macro lens. Found no interlacing issue. So it does not depend on the serial. Maybe you just have to be a bit lucky and get a 5s with a good display (as you said there are different company thatproduce displays for 5s)

The first time I saw the issue was also on my day one iPhone 5, but it wasnt as bad as on my 2nd iPhone 5S. Actually I dont believe that there are generally some serial numbers the faulty ones, but i believe there is always some bunch of serial numbers affected since they were produced together. I also think that these phones which got produced together will go in a big box together and will be delivered to the same retail place together (for example in my local Apple Store all displayed slate and white 5S have an F2 serial number and all gold ones have DN, I dont think thats just coincidence). Therefore it is very possible that one store has 95% affected phones while another maybe has 0%.
I still believe that one of the three supplier makes inferior panels which cause the black lines etc. So in theory the chances to get a faulty panel is 1 to 3. The thing we dont know is if all three suppliers really produce ⅓ of the iphone displays. Therefore the affected phones could be more or less than ⅓.
And I still recommand, if you dont see any black lines during normal usage (or have anything else that bothers you about the display) then dont even try out the test image. This thread isnt about convincing people that their good phones are faulty. It's about helping people who see the issue and are looking for advice how to get a replacement that isnt affected.

So it's really not possible to know the manufacturer of the screen? Perhaps there is some info/visible serial if opening up the iPhone. Somewhere there must be something identifying the hardware.
Maybe you can find it out if you open the iPhone, but who wants that? You will immediately lose the warranty.
And Apple will never open it and tell you afterwards which display was inside. So I guess for us consumers there is no way to find out which panel is inside. The only chance i could imagine is with a jailbreak and a terminal (I think inside the terminal you can find out which panel is inside your Mac).My only hope is that Apple investigates all the returned iPhones and if they really all have the same panel brand maybe Apple wont buy them anymore in the future. But its a very small hope...
Manufacturer of the display isn't related to serial number, so it's impossible if you don't actually open the iPhone.
Are you going to do that ?
I guess it's not really worth it, if one can't connect the serial number to the screen manufacturer.
But as sonic said, jail break and execute the right terminal command, and we might start to build some info. Not everyone wants to jail break, though.
