Is it possible to develop dead pixels over time?

I've had my 3rd gen iPad for a little over a week now. Everything seemed fine when I gave it a once over on the day I bought it, but today I noticed some dead pixels near the center of the screen.

I did a dead pixel test to see if there were others and I found several more in other areas of the screen. I could have sworn they weren't there before but maybe I just wasn't looking hard enough.

I will without a doubt be exchanging this unit, but I was just wondering if dead pixels sometimes develop over time? I will thoroughly inspect the next unit, and I just want to make sure I don't have to worry about anything popping up over time if it looks fine when I bring it home.

Dude it's just an LCD thing..I mean it's not common but LCD tvs get dead pixels all the time.

Also keep in mind a dead pixel is black,won't show any light..a stuck pixel well is stuck, so it will constantly show light or one of the three colors it got stuck on
 
Dead pixels are a manufacturing defect generally. With so many pixels in a display it's hard to manufacture panels with 100% of the pixels perfect hence why you see them on consumer-level panels (where the device maker has agreed a tolerance with the panel manufacturer in order to keep the cost down)

You can have a pixel fail during its lifetime however the vast majority tend to be evident on manufacture.
 
Careful, if everything else is awesome, maybe try to forget it, unless you look on a white screen, chances are you will not see it much in general use. it's not going to take others down with it, and it is so tiny tiny small.:p

Oh man, I hope I never find one, I'm never ever looking for one on purpose...knowing me I would lock on that thing like it was a boulder!:D

The funny thing is we all have lint or something on the screen at times, a little speck of something here or there and we deal with it, we can wipe it off if we need to but those dang dead pixels!!!...can drive you up the wall:D
 
Dead or stuck pixels are a fact of life for LCD panels and can come and go at any time during the life of the unit.:rolleyes:

Best to relax and enjoy.:)

I feel sorry for those who can not as they will ruin the experience of owning not just the iPad 3 but other things in life.:(
