iPhone 5 visual limits and distance

By Updated on

It’s pretty obvious the human eye has a limit for the amount of detail it can see, and when Apple launched the Retina display it confused some people that looked at this quality as equal to the eye. The Apple iPhone 5 is likely to feature a slightly improved Retina display, but how much further would Apple push the display considering previous comments on the Retina’s 326 PPI, pixels per inch, being the maximum an eye can see?

Our earlier article looked at Apple losing ground to LG with smartphone display technology, which is thanks to LG’s new 5-inch AH-IPS display with 440ppi, but even this is not the maximum an eye can see at 12-inches away, according to an article on iPhone Rumors. They found some old emails back from 2010 that show an iPhone 5 could stretch to 716 PPI at 8-inches away, which is what the eye can see, although most people apparently look at their phones from 12-inches away meaning the ideal pixels per inch for the iPhone 5 would be 477 PPI.

If Apple decided to somehow create more pixels per inch than this then it would be pointless, if the statements from Raymond Soneira of DisplayMate Technologies were correct. If Apple stick with the current 326 PPI found on the iPhone 4S Retina display, then this would be way under what our eye can see, and explains why LG has pushed their new 5-inch display much further.

Have a read of the article on iPhone Rumors with the key points from Soneira’s old emails, and then let us know if you’d like to see Apple push the iPhone 5 display much further in terms of PPI? Keep an eye on the Product Reviews homepage over the coming days, especially considering we have the 2012 events for E3 and WWDC about to land.

    Retina display = the eye cannot distinguish individual pixels… It can still make out the detail of more pixels and more colour depth than any phone can produce.

    Just to clarify for readers of this fine article
