I purchased the iPad 2 on launch day in the UK last March.
During the first two weeks I was incredibly bothered that I'd paid a lot of money for a screen that had light bleed on all sides. Image below.
I took the iPad back for a replacement and, whilst I don't have an image of the screen, it was marginally better.
I decided that, since the problem only exists when I'm watching movies in the dark, usually in bed, that I would try and get used to it. It has bothered me ever since but I could not bring myself to exchange time and time again in the hopes of getting a better model.
Within the past 2 weeks another problem has occured - one which, whilst maybe not technically correct, I can only describe as image burn. After browsing on Safari for maybe 30-40 minutes, on pressing the home button I would see a ghosted address and Google search bar at the top of my screen, just above the app icons, as if the image had burned into the screen.
So I took my iPad back to the Apple Store [Regent Street] today and they exchanged it.
I've just done the obligatory testing and am delighted to report that there is virtually no light bleed. I could be picky and say that there was a tiny bit on one of the shorter sides of the screen but I know that it isn't going to cause me a problem.
Hope this helps those who are still in search of a better copy.
