Screen interlacing still present on 5S

Back in the days of CRT monitors I used to be VERY sensitive to interlacing problems, but didn't notice it on my 5S. The screen is bright clear and has wonderful contrast.

Just to be sure I used the test image on the first page of posts (both setting as wallpaper minus parallax and also looking for anything while saving & shaded) and it was perfectly clear.

Guess I dodged a bullet I didn't even know was there!
 
Do you know what they call something that only you can see, can't reproduce in front of geniuses, and can't photograph or video?

No, not Bigfoot.

No, not a Samsung phone with an original useful idea.

Keep guessing!
 
Clearly I'm not the only person who can see it.

And geniuses, while some are nice, lets face it: if they were real geniuses they'd figure out how to escape retail hell

And it can and has been photographed, it's just tough to fully see as with point a lens towards any screen... Try filming a CRT monitor see what happens
 
So I went to the Apple store and was able to have my 32gb Gold 5S retail-exchanged at the Genius Bar as a result of the scan lines issue.

Unfortunately, my replacement also has this problem. It's slightly less noticeable, so I'm just going to deal with it.

With that background image, the only time I see the flickering at all is when I hold-to-save. The shaded area that is generated above the "Save Image" button flickers significantly. I can see the flickering at not other time whatsoever. I can't even see it if I set it as my background and adjust the brightness so that the image is as dark as the shaded area in the save image dialog screen. That boggles my mind a little bit. Is it possible that the flickering I'm seeing is just a product of the GUI effects generator, and possibly something that could be addressed down the road with an iOS update?

Also, is there any chance at all that it's simply something that needs time to "break-in"? I know one earlier reply said that it was, and another said that it wasn't, but neither really provided any evidence to support their claim.

These phones are brand new. My first one arrived directly from China in the mail over the course of 3 days.

My replacement one came right out of a brand new box (I watched them unwrap it and put my old phone back in it to be sent back to Apple).

Perhaps it's a problem that goes away over time? Maybe not entirely, but perhaps it becomes less noticeable?

Regardless, I won't be returning this one for this issue. It's not annoying enough to me to warrant waiting an hour at an Apple store. It bothers me that a "premium product" might have such a widespread quality issue, but it wouldn't be the first time.

I miss Steve...
 
Isnt it called the moiree effect?
On my 5c I could notice it on the dial-screen, when the numbers where sliding up. Every other pixel-row was delayed. Only for a splitsecond but it was rather noticeable.

It definitely won't go away over time. Your eyes may adjust to it or you may forget about it, but it won't go away. It appears the majority of Apple's display suppliers are manufacturing displays with this issue. In my unscientific observation, the issue appears to be becoming more common, and the fact that it's carried over to the 5s/c is not a good sign.

I'm with you though. If you have no other issues, it's not worth wasting your time trying to get replacement after replacement.

No. This is a problem with the LCD display.

No. Wishful thinking.

This has been an issue with LCD suppliers since the iPhone 3GS in 2009. Welcome to the panel lottery.

If you don't notice it during normal use then consider yourself lucky and don't try to find it.

Do these scan lines happen on iPads as well?

I've had every version of the iPad except for the 2, and I've never seen this problem.

I've also had every version of the iPhone, and many of my friends have had various versions of the iPhone, and my 5S (both the first one and my replacement) is the first phone I've ever seen with this issue.

But aren't the iphone and ipad screens the same material?

Here we go again. So I'm not sure if any of your wonderful peeps remember the issue the iPhone 5 suffered via the display. Scan lines which were thin vertical lines that some people noticed and some didn't. There was a huge thread on it here https://forums.macrumors.com/threads/1471037/. So I went to a tmobile store to potentially purchase one and had the luxury of seeing that 3 out of the 4 models on display had the issue. Then I went to the apple store and noticed only one or 2 had them. I'm confused , I mean I realize that the ew 5s is supposed to have the same panel as the 5 but you would think they would have hopefully corrected this issue maybe. Now don't get me wrong the display if gorgeous still it just feels as if it takes away from the true quality if the screen. Anyone else see this ? I had to go through 3 iPhone 5's to get one that didn't have the issue. The best way to see if you have eh issue is to use the picture below and set it as you wallpaper if your screen flickers like crazy you may have it if you do attempt this make sure to disable parallax it won't work if it's on

So I saved the picture on my iPhone 5 and it will flicker when I move the picture sideways. Is that normal? But watching it like it is doesn't cause any problems. How do I know if it's perfectly normal?

All the store display units I saw had it, the one 5S I opened up did not.

It is slightly warmer than my 5 though. But an excellent screen still..

Between seeing 11 devices (mix of 5c and 5s), only two didn't have interlacing.

2 for 11 is terrible. Good luck out there.

Isn't it likely that apple will send out units that have missed something on quality control for demos? ...as demo units will be mishandled anyway? ...so I don't think this represents the ratio you'll get with new ones for sale.

Just what does this image show me? :confused: while zooming this on my iPhone 5, moire patterns show on the right, but that's what happens when you add halftone dots, like it appears you did. ...the image on the left has much better color, but vertical lines. ...if I take a screen shot of my home with that icon, it's smooth. I don't get what this pic is supposed to show me.:confused:

I don't get it. It seems you're talking about some kind of flicker, but, I've not noticed any over the last year.

I think he's saying, if you zoom in far enough you can see vert lines on the display.


A screen shot wouldn't capture it. you'd need to take a close up photo with a DSLR or something along those lines.


The vert lines must create some kind of scrolling effect under certain conditions.

As a matter of fact, I might take a pic of my iPhone 4s to see how the screen fairs now. Lolz

That picture of the photos icon is a perfect example. This won't show up in a screen shot as it is a flaw of the actual LCD panel. Like others have said you would need to take a macro photograph with a good camera to see it in a picture. The lines are not stationary either. They scroll side to side.

To everyone that can't see this with your naked eye, consider yourself lucky and don't try to find it. It will drive you nuts once you notice it.
 
Here it is as an attachment. Thanks adoglolwut.

I have reason to believe it's LG screens that do it. Maybe not all LG screens are like this, but I think all panels that are affected are LG since I saw the same thing on Nexus 4.

It would make sense that it is since Apple has been using them more and more as a supplier that it would show up more and more.

And someone else thinks similarly:

This this. This thread should be designed to confirm your suspicions, not find reason to go looking for some if you're perfectly happy.
