iPhone 4's "Retina Display" Claims Challenged 476
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."

This sober, fact-based scientific argument will surely force Apple to adjust their bombastic, exaggerated marketing tactics.

Well, *I* recommend that you place the display right up against your eyeball and then carefully pull your bottom eyelid under the lip of the display to keep it in place.
So, technically, you can say it's recommended that you do so.
Seriously, do you have any citation for that recommendation? My understanding was that as long as you take frequent breaks to change your focal length to long distances, the risk of long-term vision* damage was low.
*I do recall reading something about problems with circadian rhythms due to electronic displays, however. But not permanent, IIRC... circadian rhythms can be reset in a few weeks.

No, no, no! Mr. Soneira has it all wrong! The math works out if you are inside a reality-distortion field, since all physical laws either change or do not apply inside said field!

For what it's worth, the highest resolution photographs are typically printed ~300ppi. This is the standard used by glossy magazines (Playboy is the canonical reference mag here).
Yeah, i can't WAIT to see Playboy on the new iPhone.

18 inches? Wow. How can you see at that distance? I don't own an iPhone, but when I borrow my friend's I typically hold it at 6-8 inches, so I can read the website text. And yes I can see the "jaggy" edges.

There really aren't first to the really high rez phone business though - my nexus one's amoled screen is about as high rez as the new iPhone's display.
Suuuure. And since, as you claim, 252 ppi is about as high as 326 ppi, 252 ppi is also about as high as 163 ppi - IOW the iPhone4 has about the same resolution as the old iPhone.
