Backlight bleeding

ovrlrd said:
Agreed about exposure, just saying that for LCD displays in general, you want to dial in the exposure as close to what you are actually seeing as possible. I can tell from that photo that it is not as bad as it looks, but I am not going to say it doesn't still look bad in real life. That is up to the user to decide.

It looks bad in real life. I'm normally a fanboy who bleeds Apple juice. If I'd had this trouble with my original iPad, I wouldn't have upgraded to the 2. It's bad. We have one that's not bad and one that's bad. We're taking the bad one in for repair/replacement.
 
I had this issue with my iPad 1, with the brightness up there were what I called footlights all along the right hand side. After the 4.2 upgrade they disappeared. I was convinced it was a firmware issue with the backlighting not dimming at the same level as the LCD.

Why some are ok I don't know. Mine is fine now. If I had been close to an apple store at the time I would have asked for a refund.

I'll post a picture later, can't do it from my iPad?

I've seen another iPad 2 right next the one I have and at 100% brightness it does not show the bright spots like mine does. That's why I will not settle for anything less.

Please, post us a picture of an iPad with no light leakage. Put us all out of our misery so we can relax in some form of comfort to know that not all iPad's are affected.

Sorry, but I can't even post a pic of my own iPad 2...

I am starting to believe it could be a glue issue..Im looking at the corners where the yellow bright spots are the most noticeable. With a completely bright white screen I do see faint yellow discoloration.
 
Grey & Blue?

I remember this controversy from the iPad 1 - Personally I'm not too convinced by screen shots where the supposedly black screen looks grey or blue. Yeah even my iPad 1 had some bleed if I turned the light all the way up and went and sat in a completely dark room. But put the light at a level where black looked black and in a room with even low light and it no bleed was seen.

There are no doubt some screens with problems but some of these are just like they hysteria from the iPad 1. Unless you can see the bleed when the black is, well, black and something else nonblack like a movie is on the screen too this isn't an issue worth fretting about.

I can not believe you people saying "Well its the photos people are taking, such a long exposure" the only reason people need to take these long exposure shot is cameras AREN"T AS SENSITIVE as the human eyes, if I just took a picture you wouldn't see it. Stop just living with these quality issues, for the amount of money we all pay for these products they should be flawless. I love Apple but I'm not going to accept "Well it happens, deal with it" the reason i never got an iPhone 4, I'm not going to just deal with having an antennae issue, and I'm not going to just deal with light leakage on an iPad 2. I for one will keep returning this until I get a flawless unit.
 
Some of the pictures of bleeding are really bad and I would try and get a different one but there will never be a flawless device and anyone that thinks that they will get one is going to be very disappointed.

"never"? I think thats a pretty strong statement. And many would disagree that screens can't be flawless.
 
damn, I hope mine won't have this problem. My first iPad had little bleeding, not really noticeable unless it was on max. Since I got it changed(for some backlighting problem) I don't have that issue anymore. If my new one will have this problem, well I'm gonna have to change that too :D
 
I'm little confused and slightly offended by some of the recent posts that seem to be pointing to this issue as either a non-issue, we're doctoring the photos by adjusting our camera's aperture or even that this is caused by pressing on the screen.

As I mentioned before - this is the first thing I noticed when I turned the display on (USB screen). I even turned it to my wife and said - do you see anything wrong here? Her response, "what is wrong with the screen?"

I've owned an iPad (1) since day 1 and can say this was a non-issue. Yes, backlight bleed does occur on (almost) every LED display. The yellow bright spots that some of us have are not normal. :(

Below are photos taken with my iPhone 4 (no flash, display brightness at 50%). As you can see I have a few areas that are bleeding - bottom left is by far the worse and the reason I will be returning my iPad for a replacement. The other spots in my opinion would fall under the realm of normal and wouldn't be a reason to return the device.

For those of you concerned with your iPads that are on the way, my advice would be - turn the device on. If there is a glaring bleed then return it, if not don't worry about it and enjoy your device. As others have pointed out - there were millions of these devices sold - to have some with issues is normal. It's not the end of the world, but when dropping nearly $800 for a device is not something I'm willing to live with.

*steps off soap box* :cool:

As usual people don't really read any of the posts properly. Nobody is saying anyone is doctoring photos, or claiming that pressing on the screen is the reason for it. What people are talking about is the lack of clear concise information coming from people with the issue. There are some good photos and some bad photos, but in all cases nobody has denied that the person has the issue, just that some of the bad photos do not really help people learn the severity of the issue.

As for pressing on the screen, that was simply an example of how you can make it worse, to help explain the cause of backlight bleeding to people who have no clue what causes it. Again, nobody was claiming that people are pressing on the screen to cause these issues.

Once again the replies to a very calm thread are filled with people who fail to read or comprehend anything properly simply because they are too upset about the problem. We get it, you have the issue, and many others do. We don't need a 20 page thread to understand that, but we can still help others understand some facts about display technology so they don't get their hopes up when the next iPad they get still has some (hopefully) extremely minor backlight bleeding.

I will reiterate: Not everyone will experience the same level of backlight bleeding, and some people will find it tolerable and some people will not. The fact remains that all edge lit LCDs experience this problem to some degree. It simply varies how severe it is, and how visible the bleeding is. Replace it if you don't like it, or get a refund if you aren't happy with that. Just don't expect to get a flawless display, it will never happen as long as Apple uses edge lit LCDs. It is possible to get one without the severe backlight bleeding that people might be experiencing, so it is definitely worth replacing, but really only if it's clearly visible and bothers you (especially in a room with the lights on).

I just made this image. ;)

Anyone fancy playing a mean naughty prank on someone else and setting this as their iPad Wallpaper?

:D

I can wait

Having read much of this thread it amazes me the extent that many will go to rationalize what are obviously screens with bad mura, and otherwise excuse Apple from responsibility. Like, for instance, suggesting one should just find an iPad with minimal bleeding. Really? How many returns and how long might that take?

One would think the best way of finding an iPad with a proper screen would be in visiting an Apple store and buying it . . . because they had previously checked every one going out the door with an eye towards quality control.

My idea of quality control is to hold off on buying an iPad2 for now. With luck Apple will at last sort this out, or perhaps their unfortunate customers will have to do it for them. But one does not have to be among them.

Hopefully the overall percentage of new iPads with this glaring problem are relatively few. But from the pictures I've seen, if suffering this, unless a masochist, my suggestion to return the defective product to Apple ASAP.

All this unfortunate, and avoidable.

From people who have done it so far, it sounds like only one exchange was necessary. Minimal bleeding is the best you can hope for, it's just the way the technology works. Sadly people like yourself are taking "minimal" to mean visible bleeding, when in fact everyone else is just saying it means that it takes a sharp eye in the right environment/settings to even notice it. Severe/extreme bleeding are people with visible spots, particularly even in rooms that are lit or at 50% brightness, these iPads should definitely be replaced/refunded nobody is questioning it.

It's great everyone saying their iPad's aren't affected and all, but could they kindly post such an image? It's not that we don't believe it, just that there isn't really such an image at the moment.

As far as anyone that has gone to return their iPad, have you had any issues doing so? I purchased another one online, thinking it would be easier than having to wait for a replacement - but, it sounds like the Apple store might have replacements in stock. Is that correct?

Thanks for the help.

Cheers.

Ooooh here's some speculation for you... the glue that is used to bond the panels is translucent when wet (perhaps because tolerances are automatically checked with a laser or light-emitting device) and opaque when fully dry? I just pulled that hypothesis out of my butt, but anything is possible.

It's been noted that that is a possibility. The glue may dry over time and lessen the problem. Only time will tell.

If mine has the problem, I'll give it a couple of weeks to improve, and if not try to exchange at an Apple store once stock is hopefully more available for exchanges.
 
Can someone with the screen issue please post a photo of their iPad 2 playing Westlife's video "obvious" in a darkened room.

I want to see the bleeding obvious
 
Man some of these posts here that say this is a non-issue and tell you to deal with it and that this is "common" with LCD tech's -- makes me want to punch my screen. This is clearly a problem and the screen should not look like that. Compare it to the Xoom's screen FFS -- After all Apple crapped all over honeycomb \ android in their iPad 2 press event. I haven't seen any articles about the Xoom's screen having light bleeding problems. I'm going to follow up with the guy from apple exec who contacted me tomorrow morning. Hopefully he'll have some news...
Also -- I don't think this is "mura" -- the bleeds leeks would be white, not yellow right?
