iPhone 4's "Retina Display" Claims Challenged

Posted by timothy on from the obviously-you-need-an-i-retina dept.

adeelarshad82 writes "Of the many things that buyers might need to know about the new iPhone, Raymond Soneira — president of DisplayMate Technolgies — added one more to the list. Soneira challenged Apple's claims that Apple's new iPhone contains a so-called 'retina display.' According to Soneira, the resolution of the retina is in angular measure, 50 cycles per degree, where a cycle is a line pair, which is two pixels, so the angular resolution of the eye is 0.6 arc minutes per pixel. So, if you hold an iPhone at the typical 12 inches from your eyes, that works out to 477 pixels per inch. At 8 inches it's 716 ppi. You have to hold iPhone 4 out about 18 inches before it falls to 318 ppi. So the iPhone has significantly lower resolution than the retina."

    I'm not sure how discriminating your taste is, or what your preference is, and I assume you're male...

    You are aware of what kind of person would be laying you because of your iPhone, right?

    I mean, they probably wouldn't be nerdy *AT ALL*. What good is that?

    Android OS is not actually an operating system by or for Androids.

    Windows 7 wasn't really the idea of some random people in cafes and showers.

    Saturns - not actually made on Saturn. Surprising, I know.

    The Emotion Engine has never shed a single tear.

    My boss just walked by my desk and saw me holding a 12" drafting scale and cell phone to my forehead. Thank you slashdot.
