Penn State University’s PhD candidates Ryan White and Bryan Gauntt put the new iPhone 4 Retina Display under a microscope and compared it with the display found in an iPhone 3G. According to their measurements, the iPhone 3G’s pixels measure 13 x 40 microns, while the iPhone 4’s measure 6.5 x 20 microns, which adds up to exactly four times as many pixels. These numbers are not surprising at all as Apple already announced that the new display features 4x the resolution found in iPhone 3GS. What is surprising is the difference that someone can see in the images from the microscope.
The images clearly show the superiority of an iPhone 4 display. There has been a lot of controversy with the new iPhone 4 Retina Display, with Apple claiming that the human eye can not differentiate the pixels of the display while others claim that this is not true. However, for everyday use, what is important is how the display looks. And according to all reviews, the new display looks great.
