Experts Skeptical About Apple’s New iPhone 4 ‘Retina Display’ Claim

While unveiling new iPhone 4, Apple CEO Steve Jobs went on to make several claims about multifarious features of the fourth generation iPhone. One of the notable claims was that iPhone 4.0 has image resolution which is comparable to human eyes i.e. perfect vision or ‘retina display’.

Experts including people from medical science went on a treasure hunt to find the authenticity of the claim. Dr. Raymond Soneira is one of the experts who scrutinized iPhone 4’s this special feature. Soneira’s company makes software to test display quality. Soneira, however, differs from Jobs over Apple iPhone 4’s reported retina display.

“The iPhone 4 has an outstanding display… and I’m glad that Apple resisted the emotional rush to OLEDs because they still need lots of improvement before they will be ready to compete with the highly refined IPS LCDs. The iPhone 4 display should be comparable to the outstanding IPS LCD in the Motorola Droid, which I tested and compared to the Nexus One OLED, which was trounced by the Droid,” the expert said in an email as reported by PCWorld.

Soneira also explains how Jobs’ claims that iPhone 4 has a resolution higher than the retina is not right:

First, resolution of retina is 50 Cycles Per Degree. A cycle stands for one line pair i.e. two pixels. Thus the angular resolution of human eye is 0.6 arc minutes per pixel.

Second, if you see the iPhone 4 screen from normal distance of 12 inches, the screen appears to be 477 pixels per inch. At a distance of 8 inches, it’s close to 716 ppi. And from 18 inches, it dips to 318 ppi.

Thus, Soneira concludes that new iPhone’s resolution is pretty lower than of the retina. He said that iPhone’s resolution needs to be higher than the retina in a bid to achieve an image that is closest to reality.
