When Steve Jobs unveiled the iPhone 4 last week he made a big point about the new so called retina display. With a resolution of 960x640px on a 3.5-inch screen the pixels per inch reach 326 pixels per inch density.
If you view the iPhone 4 screen from 10 to 12 inch distance your eye would not see any pixilation. On Friday we reported about Dr. Raymond Soneira saying that the iPhone 4 has not a Retina display based on his calculations.
Phil Plait on his blog on Discover Magazine brings more light into the controversy.
He explains that the calculation of Dr. Soneira is based on 0.6 arcmin for the eye's resolution. This resolution only is true for perfect eye sight, which most people do not have. 20/20 classified as normal vision has a resolution of 1 arcmin.
Doing the calculation with that value the claim of Steve Jobs is true, the iPhone 4 has a Retina Display.
