I find these type of screens interesting. My portable gaming system the GP2X Wiz uses an AMOLED screen. These were sold a few years ago, and most of them have died to do "pixel plague" because the organic material, got bacteria eating the screen away to nothing. Ugh.
But mine has NEVER had this behavior, and still works fantastic. Mind you, I'm a CRT fan, I feel CRT's are the best when it comes to color purity and black levels, and I still feel LCD's can not touch them.
But the AMOLED on this little game system has some very serious color quality, and a black levels. This is a rather interesting technology, and probably the only competitor to CRT, in my opinion.

That is some very saturated colors there! Now of course, maybe TOO saturated, but in person, this is a very nice and pleasing picture.
There's only one problem with it's screen though, it can't do blue. It's blues have a very indigo look to them.
