Far from ready for practical use? That's an odd statement seeing as AMOLED screens have been in production for MANY years and for pictures and video, offer a significantly better image quality than alternatives. Some may prefer, some may not (I do), but to state they're far from ready for practical use shows your lack of screen technology knowledge.
Not at all.
I've seen AMOLED screens by the dozens, and all of them suffer from oversaturated colours, blueish or greenish tint issues depending on the viewing angle, aging issues (very apparent on phones only a year old...) and a lack of brightness under bright daylight. Not to mention the artifacts caused by pentile pixel arrangements. Say all you like, the technology is still in it's infancy. It what you're claiming would be true, why are virtually no manufacturers of digital camera's applying AMOLED display's on their cameras?
I really do see the potential advantages of AMOLED technology, but I find today's real-world appliances of the technology highly inferior to good LCD-IPS screens like those on the iPhone or the HTC One X and One.
And this is coming from someone who still prefers a plasma tv over an LCD tv. Don't try to assume I don't know a lot about display technology, thank you very much.
