Helpful video. So if you turn the brightness way down and never watch videos and always point the screen away from you, you won't notice any bleeding. I guess there's nothing to worry about after all.
I really doubt about it.
I hope, but i doubt.
I'm Italian and I expect to get my ipad2 32Gb +3g on 25th of march and I'm pretty sure it is somewhere already boxed.
I seriously doubt that the production will fix this problem for the international launch.
Moreover I already fought with this problem with my last TV Led, and the only way to skip the clouding and bleeding mess was to change technology.
EDGE LED sucks big time imho.
My advice to everyone who has an iPad2 with back light bleeding is to return it. This is the only way Apple is going to deal with the problem. Don't get me wrong I am an Apple fan who owns several Apple products, but I have returned 3 Apple screens in the past (with absolutely no problems) due to back light bleeding.
Naturally, some people will not notice or mind the problem, but for others who enjoy looking at photos, playing games, watching videos etc, back light bleeding can be very irritating.
Apple are a quality company, that usually make quality products. I can certainly vouch for their excellent quality, customer service.

^^^ I second this. These screen issues might be expected to arise in cheap products from third-tier off brand companies--but not from apple.
I was just reading something interesting in the Anandtech review that might help explain why the backlight bleeding varies so much.
So basically there are so many variables that basically make it completely random how severe your backlight bleeding might be.
Also to people who keep saying these problems shouldn't be happening from a company like Apple, you have to realize that Apple does not build the screens themselves, and they don't even assemble the iPad themselves. There are many companies at play here, and this kind of thing happens with all Apple products.
It is all industry standard parts, so product pricing has nothing to do with it. You are fooling yourself if you think paying for a certain brand automatically means there should be high quality parts. Every company uses the same manufacturers as Apple if they are using edge lit IPS panels.
Please stop making Apple out to be the bad guy here, they will gladly refund you or replace your iPad if you aren't happy. But they aren't going to change the manufacturing process because they are not the ones responsible for that. You might as well stop buying edge lit LCDs from every maker out there because that is the only way to avoid this issue.
One time I went through 5 Samsung HDTVs to find one without severe backlight bleed. Eventually I found one that had only minimal bleed and stuck with it. I suggest you do the same, find an iPad with minimal bleed and be happy with it, or get your money back, because that is all that can be done. Nothing will change from Apple or any other company until something replaces edge-lit LCDs entirely (maybe OLED?).

That's idiotic.
It's a issue with the IPS display? What's he talking about, it's got nothing to do with it being an IPS display, any LCD display type has this issue in varying degrees, from an iPhone size right up to a 50" TV.
Total pot luck and down to manufacturing/quality control.
If you can make one with almost no light bleed, and you also make them with a lot of light bleed, it's obviously a manufacturing issue. It's not an act of god!
Mostly it appears to be caused by pressure on the screen.
On one of my monitors, if I display a black image in a dark room and then squeeze the bezel of the monitor (not touching the actual screen) I can cause light bleed patches, as I'm very very fractionally putting pressure onto the panel.
I do wonder if this is the case, here also. It's probably a combination of the tolerance in the panel, and then how the panel sits in the iPad's frame and any extra pressure the glass puts onto the screen as it's glued into position.
Note: If you can make good ones, then you can make them all good.
It's how much it would cost to tighten up the quality control of panel manufacture and assembly.
Have some slight bleeding on the lower right side. If I press the glass hard there I can make it worse but the fix for that is simple - don't press the bezel there! None of this is visible with an actual image lighting up the screen. I'm ambivalent about returning it as I could get a worse one or get bad pixels. In either case there are none left at BB for at least a week so I would have to call Apple about it and I'm not sure they would agree it is a defect. right now I'll just monitor the issue for info.
Mura
This kind of problem is called mura. It is found on LCD displays when viewing a dark state in a dark room. It is fairly common on TVs, particularly in the corners. It is caused by stress in the glass that can rotate the polarization of the light slightly, effectively opening up the LCD light valve a little. Stress can be caused by how the glass is held, or heat. It is not an indication of any kind of panel degradation and is harmless to the LCD. Because the display is thin it could also be a function simply on how you hold it and it will change and it is a function of how you bend the panel. It could also be a function of the polarizers in the panel, but that is less common. You should not see it in a room that has lights on.

Finally someone else who knows what they are talking about. Good post, hopefully will help explain to people what is going on.
To be polite, this is not really what's being talked about "Specifically"
The clouding phenomenon affecting some large screen LCD panels is increasingly recognized as mura, a Japanese term for unevenness used to describe a low-contrast and irregular pattern or region causing uneven screen uniformity under certain conditions
It just means unevenness anywhere on the screen, it's just a general term for something that's not perfect.
Whilst, naturally it does cover this fault, it's just a general term.

I contacted Apple about my problem because of how bad it is. The first guy said there was no such problem with any Apple products and he insisted that I return my iPad to Best Buy. To me this was not an option because of the short iPad supply. After a while of explaining the issue to him I got the Senior Advisor. This guy was nice and understanding. I told him about the yellowing/backlight problem and also how my iPad came fresh out of the box with three small nicks in the aluminum back. I basically insisted that my iPad be replaced by the warranty because returning it to Best Buy was not going to happen. He gave me three options:
1. Return it to an Apple retailer
2 Apple will over night me a box that I will put my iPad in and send to the closest repair facility. They will then send me a brand new unopened iPad replacement.
3. Apple assigns me a 'Repair ID' and I take the iPad to UPS with the Repair ID and UPS boxes the item and sends it overnight to Apple. They then Overnight me a new iPad.
I went with option 3. The guy assured me that my iPad would be new. There are currently no refurbs available since launch just happened. He said the process will take about 5 days. Hope this helps, I was not happy that my Black 64GB Wifi iPad had a defective display. If the next one comes the same way I might just return it for a refund. Not cool.

I think it's pointless to hurry up and return one now unless lack of a perfect screen means you just want a refund. Mines got the same issues to some extent but I figure if they eventually change the manufacturing process, it will be a matter of at least weeks if not longer, and the warranty is good for a year. So, I'll wait it out.
It's important to remember that people with problems are more likely to post about their problems than people whose product is working perfectly fine as it should. That's just human nature, and has always been the case here at MacRumors: people complain when something is wrong, but nobody makes a thread saying "I have no backlight bleeding".
This is just to caution those of you waiting for your iPad that it's not a foregone conclusion you'll have these bleed issues, as the number of people voicing their displeasure always heavily outweighs those singing their praises. With that said, I'll still be keeping tabs on this thread.
*crosses fingers*

But we also have to remember a lot of iPad owners and "not tech" consumers who just don't understand things like this and will never complain or even notice it unless it's pointed out to them.
The 1st wave of buyers are more techy people I'd guess.
Sorry dude but they just can't change the manufacturing process, they would have to change the design of the iPad to no longer be edge lit backlighting, and that just is not going to happen.
You are better off exchanging it until you get one with the least amount of flaws. They will all have a tiny amount of bleeding, and if yours doesn't have very much then don't even bother exchanging it.
I will repeat myself. All edge-lit LCD panels experience varing levels of backlight bleed. It is extremely hard to avoid and not something Apple can help when they are sourcing multiple panel makers to supply them. You think iPad 2 supply is bad now? Just imagine how bad it would be if they had to throw away all the ones with even a tiny amount of backlight bleed. It would 90-95% less stock available. Meanwhile probably the vast majority of the current ones made have only extremely minor bleeding that is not really visible in most cases.

Did I say I was upset or angry? No...I said it's minimal and not an issue.

Those people must obviously be delusional or masochistic in other areas of their lives. Or maybe they have really low self esteem. Those are the only explanations I can find for people justifying an obvious screen defect. And just like with "antennagate", this is how it starts. If it were only a small percentage of users experiencing this, you wouldn't see as many posts about it. It's a real problem that appears to be affecting a lot of customers.
Mura
The only problem with knowing about mura is that now that you are aware of it you will be seeing it everywhere, as it is pretty common. Just go down to Best Buy and look at an LCD TV in a black state in a dark room. Most people don't care about it and don't notice it. I suspect you will find it on iPad1, but iPad2 may be more prone to it because it is thinner, making it easier to stress the glass by flexure, causing stress birefringence in the glass, which very slightly rotates the polarization of the light, allowing light leakage.

You have a 1 year warranty. Because of how the new iPad is assembled, it's probably not a highly repairable item. If you have an issue during your warranty period, you'll most likely receive an exchange. iPhones get exchanged for refurb units, probably the same with iPads.
You're kidding, right? That photo was taken in normal room lighting. In my opinion, the photo on the front page is terrible simply because you don't need to be in a dark room to see it. If you can see it in a normal or dimly lit room, it's defective in my book and should be replaced.
Apple is known for high quality, why are so many people making excuses for them?
Doesn't look like a dark room to me...
Judging by the number of people posting with problems, I'd say the numbers are as bad or worse than "antennagate". Whether it gets traction in the mainstream media is a different issue. We may need Consumer Reports again...

I would send the iPad back. This is unacceptable and I don't get people who say it is ok. It isn't!
While you can't change the manufacturing process, you can tighten manufacturing tolerances and increase your QA standards or qualifying procedures. The fact that so many of these are finding their way into consumers' hands means that the level of light bleed on your unit met with Apple's stamp of approval. That is troubling.
The iPad 2 disappointed us on so many levels. Now they can't even get the screen right.
