To add another data point. I picked up a week 39 phone this past Saturday (Oct. 20) and my screen has a -slight- problem with the blacks. It's not bad enough IMO to take it back at this point. If I watch more videos and it gets annoying, I'll take it back.
Week 39 - screen 7455232 - slightly negative
Week 39 - screen 7455232 - slightly negative
Incorrect. The issue correlates more so with screen model than specific week of production.
Having said that... I have wk 39 with 7459072. Perfect.
Just curious, on the home screen top bar where the time is displayed, what does the gray look like on your iPhones, warm or cool? Here is a Wikipedia page that displays a comparison..

I'd like to add my experience. I got an iPhone last Tuesday, week 39, serial 7R739***. It definitely had the negative screen issue and was the bad 7-series LCD. From what I read, it seemed like the Apple "Geniuses" were reluctant to admit the problem, so I prepared myself. I got my test picture on my web gallery so that I could load the same picture on different phones. I scouted out an iPhone at the store that didn't have the issue (most of their display models had it, all week 32 phones) and picked out the exact one I needed to use for comparison.
Needless to say, thank goodness I was prepared. I was first told to turn up the brightness. Then I showed him the picture on my phone and the one on the good display phone. I then got the canned "it's within spec" response. I stood firm asserting that there is definitely something wrong when on one phone, the person looks fine, and on the other, the person looks like a zombie. After a minute or two of this, he conceded and went to "speak with someone in back." He came back with a white box phone (sticker priced $249.00!? for an 8gb) saying that he can only allow me to exchange it once since it's not a defect. Before I signed the receipt, I made sure that the LCD was good and it was. It's a 5-series.
It seems like the they know there's a problem but try to brush you off. You have to stand your ground to get them to replace it.

Following up on my "slightly negative" display. I tried to watch a video last night and it was almost unwatchable due to the horrible lack of contrast. I think that's really the problem here. There's not even a contrast control on the settings screen that you can play with; only brightness.
I made an appointment at the Genius Bar for this afternoon, so I'll see what they have to say. I'm not taking "no" for an answer.

Oh god how I wish I wouldve gotten a 5 series screen. The one they gave you was a refurb, they did the same to me. The new one I recieved at the apple store had no negative blacks, but it has lines going side to side, kinda hard to notice when just navigating around the phone's ui, but once you play a video it gets pretty annoying, its like watching interlaced video on a computer. I called up apple care again, and once again, my phone's going back to them and im sure it'll come back as "unable to reproduce problem" again.
My first one had it pretty bad, but I just got it replaced a couple of days ago because the volume buttons were faulty. This one is perfect.
I noticed the same issue on the 7459072 replacement that I received which was also a refurb. The horizontal lines are very subtle but they cause things on the screen to shimmer momentarily when you focus on them for the first time. It definitely looks almost like an interlacing effect. I *do not* see this on the 7455232 LCD comparing the two side by side. I think I saw the same effect on several iPod Touch display units I saw in the store.
By the way, is your refurb a 7459072 as well?
Yup. Have you already gotten a good screen? How many times have you had to exchange your phone so far? The lender phone that apple sent me has a 7455232 screen but it has the negative effect on it. They made me send them back my phone so it can get checked out, but it's just going to be a waste of time and im going to have to call them back after I receive it. Im thinking the line effect might be able to be fixed in a future firmware update, but im not sure.
Are those of you with GOOD screens encountering poor contrast? I don't exactly have the negative blacks issue, but I do have terrible contrast on my screen - the blacks are WAY too light, causing a lot of darker stuff to wash out completely.
This is what my screen had. Any of those screens with the 7455232 ID without the negative blacks are this type of screen -- poor contrast and washed out black. You may even have the white dot grid problem. I had trouble watching video on this and exchanged it. Got a 5-series screen and am happy with it
The contrast is not as high on these compared to 7-series phones, but they are set to a higher brightness setting and you can see dark colors better. Also the whites on 5-series are more natural, whereas 7455232 whites are yellower. From the 7459072 I had, it was set to a blue tint and compared poorly to the 5-series as well, although it didn't have any negative blacks. Bottom line if you want for sure the best screen out there is to go out and get a 5-series. I believe me and another user both got 7U739 and came up with a 5-series screen. Hope that helps a little!And so a question about the 5-series screens, were there a lot more of these in the phones before the price drop?
I posted pics of a show on my iPhone for a Touch user to compare to:

The pics don't do it justice. My screen is awesome. I have a close-out 4Gig iPhone, week 29.
The iPod Touches Week 37 at the Apple Store I frequent are awesome too...
Oh I know that pre-price drop screens were good, which is what your iPhone is. But it seems that almost all screens after the price drop have some type of problem with them.

And so a question about the 5-series screens, were there a lot more of these in the phones before the price drop?
I went in to the Apple store and was there for an hour and a half trying to get the staff to admit to the contrast problem on my screen. None of them were willing to admit what seems to me to be patently obvious - iPhone LCDs (all the ones I've seen so far) have terrible contrast ratios. They treated me like some kook who complains irrationally about everything.
I finally got them to agree to an exchange within 30 days, but it took a LOT of complaining and putting up with some pretty snotty, superior attitudes on their part. I'm NOT impressed with Apple Store customer service on this issue.
Yea, this 4 Gig phone that "no one wanted" turned out to be the $299 gem...
Welcome to lower prices... (Wal-Mart?)
It's not really like we can tell apple "hey charge me 600 and give me a good screen while your at it". Anyone who buys an iPhone has to deal with this now.
