Hey, while discussing the Galaxy with a coworker today, he mentioned that OLED displays 'wear out'. That was the first I have heard of it, so I looked it up.
The biggest technical problem for OLEDs is the limited lifetime of the organic materials. In particular, blue OLEDs historically have had a lifetime of around 14,000 hours (5 years at 8 hours a day) when used for flat-panel displays, which is lower than typical lifetime of LCD, LED or PDP technology—each currently rated for about 60,000 hours, depending on manufacturer and model.
Now you know.
I suppose there's a chance the Galaxy's AMOLED display begins to show signs of wear after, say, 3-4 years, but I guess that's acceptable. I don't know what a worn display might look like; the best example is this image, also from Wikipedia.

The Wikipedia page is talking about OLED diplays. AMOLEDs are more refined. I'll try and find some wear and tear stats, but I wouldn't be surprised if they last longer.
Plus 5 years for a phone is quite a lot. (do you use your phone with the screen on 8 hours a day?). At a max I would guess four hours, but that's still a lot, so really the expected life is closer to 10 years, which is more than enough in my opinion.
The lifespan of the material itself draws near 10,000 hours already, and it has been developing by more than 30% every year; it is expected to achieve 40,000 hours of lifespan in year 2005 when AMOLED is regularized.
Sorry, I didn't mean to say that you didn't have a valid point. It's good to make people aware of these things. I just really like researching things and backing it up with evidence (I can't help it, I have just completed a science degree at uni).
It's just that I think you will have broken the phone, the battery will be flat, or any other combination of things before you have to worry about the screen going on you. Or you bought a new handset with a 2 GHz processor with a full HD 3.2 inch display
Not really something to worry about at all. By the time you have used the life out of the screen you will probably have broken the phone some other way or at least be itching for a new phone.

You're telling me. I bought my HTC Diamond in February and I've wanted a new phone for a few months now. That's partly cause it is WinMo and I hate it, hopefully next time since I will get an android phone I will be able to look after it longer.
Unfortunately wear and tear can show sooner than the manufacturer provided number of hours.
I've had my phone (Nexus One with the AMOLED screen) plugged in all day at work for some months and when plugged in, the screen didn't go to sleep, resulting in a burn-in of my homepage. It's usually not noticeable, but on all-white screens there's clear shadows from the burn-in.
I know this is not completely on topic, but it's a warning (and a lesson learned for me) to others, on not to take these numbers too literally.
