I'm sure many of you have read the article on engadget where Samsung touts their AMOLED display saying its pretty much in all ways better than Apple's retina display. If you haven't, the article is here. http://www.engadget.com/2010/06/09/samsung-iphone-4s-retina-display-is-nice-but-its-no-amoled/ I'm interested to see everyones view on this. I know none of us have actually had hands-on time with iPhone 4, but let's look at it from a technical perspective. I'm not doubting that AMOLED is more energy efficient, and perhaps even has a slightly better contrast ratio than IPS, but honestly, what I care most about is definition and clarity. Samsung claims that the retina display is only 3-5% sharper than their AMOLEDs....well correct me if I'm wrong, but the PPI on iPhone 4 is about 320, and by my calculations, the PPI on a 4 inch AMOLED with a 480X800 res should have a PPI of a little over 200. I'm not sure how each pixel relates to sharpness, but i do know that a PPI of slightly over 200 is definitely not over 300, therefore pixels can be distinguished by the human eye. This is why, IMO I think I'll prefer the Retina Display. Anyone else?
