When Steve Jobs unveiled the iPhone 4’s quadruple density new Retina Display, he said that the pixels weren’t visible to the human eye. His exact words?
It turns out that there’s a magic number right around 300 pixels per inch that when you hold something around 10 or 12 inches from your eyes is the limit of the human retina to differentiate… and at 326 pixels per inch we are comfortably over that limit.
Well, Wired wasn’t sure about that claim, so they went to an expert, who has mightily disagreed.
According to him, once the optical conversions take place, at 12 inches away, the retina resolving power is actually far greater than the iPhone 4’s: 477 pixels per inch, instead.
Jobs, the man who shouts “magical” and “revolution” for every new product launch, hyperbolic? Forsooth! But it’s actually moot: even if you can see the pixels (and we doubt it — most people operate their phones at over a foot away), the iPhone 4 still has the highest density smartphone display in the world. Saying anything else is just splitting hairs.
