Screen interlacing serial numer starting with F2

No, you're just supposed to set the picture as your wallpaper without tweaking it, or else it won't have the same effect. The vertical lines will show for both phones that don't exhibit flickering and those that do. The phone flickers because there's an interlacing issues when you can see tiny vertical lines when looking at colored backgrounds. It only flickers when there's dark area, like near the dock, or when you're setting the picture, where the share, start slideshow, and delete buttons are. It's not about flickering, it's about the lines. Like someone repeated, the flickering is just a byproduct to test if you have interlacing/vertical lines. The picture that someone posted is a perfect example of what we see, and it's hard to reproduce on a video camera.
See how there are vertical lines going through that are more apparent on the left picture? It makes things look pixelated at times.
And to repeat, mine is an F2 week 40 with interlacing. I might replace mine at the end of the week to see if I can get one without interlacing because it's pretty lame that I knew I had interlacing before I figured out that it was interlacing, if that makes any sense. The number one thing that bugs me with phones are display issues (which I tend to notice right away, especially in this case), next to cosmetic issues. I'm just crossing my fingers that the replacement doesn't have any hardware or cosmetic issues.
"Apparently"
The screen door effect is a Moiré interference pattern. It will affect any display, not just the iphone.
The image will display fine when it's static, but the patterns appear if it's resized, rotated or animated. With the coloured subpixels, you get those funky purple and greens too. It happens when you try to display one grid pattern over another. One grid being the image, the other the pixel grid. That image is a worst-case scenario for triggering the effect!

The problem we are seeing is that the image flickers on a still display. Screens with this issue will show flickering when you set the image as your home and lock screen.
And even then, the problem isn't the flickering (because really, who's going to have that set as their wallpaper), it's the lines...
I agree. It's mostly the optical illusion of the lines.
Real flickering and defect issues are shown on Youtube . Mostly happens with the keyboard
I have an F2 (week 39 black) with fairly bad screen flicker. I thought I was imagining it. It appeared as though I could see pixels. I agree with the OP, my (original week 36) launch day iPhone 5 had a flawless screen with no flicker.
I am wondering, does anyone else have a yellowish tint on their screen? My first iPhone had an amazing screen but this current one looks awful. I'm just wondering if there are some sub-par displays being used that contribute to flickering and yellow screens. It also doesn't help having good eyesight...
Side note: To the guy that said that Apple QC is slipping. It may be. But I would argue that Apple has never faced such universal demand. Sure, many bad units will slip out but I think they are in the minority (a vocal minority indeed). Also, I want to point out that it's not Apple that is slipping specifically, it's the production partners e.g. Foxconn. China is possibly facing a revolution in the labor market not making things easy for the workers and for those in charge. Foxconn has already stated that the iPhone 5 is the hardest device to manufacture that they have ever encountered. Apple is always on the cutting edge for production techniques and has billions of dollars at their disposal. If Foxconn can't do it, they will take their business elsewhere. The stakes are very high and this is no easy task. I'm sorry for the rant.
TL;DR: It's not Apple, it's their production techniques and the suppliers are struggling to keep pace.

C3 and it flickers in the part where it says slide to unlock and the image gets darker. And my home screen flickers too. When I launch or exit an app it goes crazy with vertical colorful line. I haven't notice anything before this and I'm not going to return or exchange it.
The problem with the flickering this is: it's real, not imagined, and cheaper phones from lesser quality manufacturers have better screens.
Go look at an HTC One X screen. It is made by Sony. It is the best screen on a phone today, and no one can argue this (although i'm sure people will). No flicker at all on that screen.
Went through 5 iphone 5's and they all have flicker. Sixth one did not. It had a chip in the aluminum instead, but whatever, I'll live with it. By the way 5 out of 6 also had chips/scratches.
Please. It was the best screen, and maybe not even that (the GSIII gets compared far more, although I HATE pentile). The experts are now saying the 5 has the best screen and possibly out of any device consumers own. It's got very accurate color reproduction. Plenty of articles on it.
Mine is DN no issue at all. Just got it today.

Funny you mention the HTC One X because the first time I saw it on display I was disappointed with the screen because it actually had the exact same vertical lines except even worse than my iPhone. I was really confused because all the reviews said it had the best screen. I have since seen other One X screens and now know its not typical.
I really think these things cost a company its reputation especially those who don't understand the manufacturing and follow tech sites. All they see is a supposedly new phone they signed a multiple year contract for and it's dented or has screen defects.
F2 replcaement phone here. I just fell upon this article and mine suffers from this interlacing issue. I have an appointment with the Genius bar to have this replaced. Also, when switching between applications is when its really apparent with mine. I see a bunch of wacky colored lines appear and then go away every time I switch apps. I'll see if I can snag a pic of it.
Yes, if you can get a picture of it, that would be really helpful so we can see exactly what your interlacing looks like.
This is what it looks like in process of quitting an app except the lines are colored and flicker.

Does it do that only with that "special" grey image as home wallpaper or all the time regardless of the background?
Someone mentioned it was normal to see discoloration when switching and closing apps because the software tries to assign proper pixel color and it confuses the GPU or something (when using the OP's image)

I just saw the post above on this page, my bad. Yes it only does that with that special wallpaper. So I guess mine it normal; although it does flicker on the home screen near the dock where the wallpaper turns a darker shade. I realize now its about that lines. So I guess I'm ok.
I would say so. If it is not something you noticed until this thread, I wouldn't worry about it especially if you don't see any symptoms during day to day operation, gaming, etc. You might really regret getting it swapped out and entering the iPhone 5 lottery...
Ugh this is frustrating. This is my 3rd iPhone 5. First, had headphone issues and the 2nd the screen was coming apart/clicking in the upper left hand corner. With the replacement I got last night, I noticed when I got home, the latest replacement screen looked weird. Kind of pinstriped but only certain times. It's really noticeable when I'm in the email or settings app and the blue status bar looks kind of pinstriped. It's annoying which I was willing to live with until I noticed what looks like dust or a dead pixel. Have an appointment with a genius today so hopefully they will swap it out, but I think it will be more for the dust under the screen rather than the interlacing. Just frustrated that all this is starting to happen after the 30day return period. So I guess maybe 4th time is the charm?? 
For the record, I have an F2 serial number.
