A note about retina displays and the iPhone 5

A note about retina displays and the iPhone 5
The Korean Times report which told about Samsung being the supplier of the quad-core A6 chip for the iPad 3 and iPhone 5 also mentions that it is likely that LG will continue to be the supplier of iPhone displays. Unfortunately, there seems to be some confusion over the term "retina display", which is misused by the Korean Times. 

LG has been the supplier of past iPhone displays, and is reported to keep that coveted position. The trouble is that the rumors don't fit with Apple's current "retina display". It is rumored that the iPhone 5 display will be 4" and have the same resolution as current iPhones at 640x960, but this would mean the screen would have 288 pixels per inch (PPI). The idea of a "retina display" is that the screen has a higher PPI than the human eye can discern, and the number for that given by Steve Jobs (which is under debate) is around 300 PPI. So, putting the same resolution in a larger display would remove the self-applied "retina display" name.

It seems unlikely that the iPhone 5 would keep the same resolution if it makes the screen bigger, because that would cause it to lose "retina" status, and there is almost no way Apple would give up that marketing chip.

I think Apple would increase their resolution before going with a bigger screen

I am hoping with all these 720p displays rumored to be coming out soon that Apple will indeed increase their screen resolution to counter them. And with that increase resolution, hopefully an increase in screen size as well.

I think its obvious that apple will do the same in the iphone5, even if their screen reaches the 4' area I still believe the pixel density will either be equal or higher than the iphone4, its kinda their signature.

if they increase resolution, wont devs have to code for that? the only reason i can think of that they dont maintain ppi is to make all current apps compatable. and if they do stick with the current resolution, they will surely redefine retina display. something about how far you hold the phone or something. they'll figure out how to hold on to their marketing scheme

yes aye, the devs will have to code in and check compatibility for the new screen resolution. Im pretty sure thats why they didnt do it this time.. making sure 400k apps are compatible is going to be a mess. At some point they have to bite the bullet as 3.5 inches just isnt cutting it anymore as noted by "what did you want the most" articles.. they all want a bigger screen. They could have probably expanded it to 3.7 inches and gotten away with it, but anything higher is going to be a new resolution.

3.7 just wouldnt be worth it (i dont think). they really need to take the leap, decrease bezel and increase screen size/resolution.

Didn't LG make an HD display?? So why cant apple use that on the iphone 5? Even if LG doesn't let them Samsung and sharp all ready have HD displays so the technology is out there so the question is whats stopping Apple from making there own?

Did you know that if you were to be 15 feet away from you 1080P hdtv while looking directly at it, it would have more ppi than iPhone's "retina display"?!

I did not.

Hey, PPI means "pixels per inch". Inch has the same size on every distance! There is no PPI variable on some distance, despite the fact that it does make a difference to viewer.

true. the pixel density would be based on screen size, not distance of the viewer.

So if I'm really close to that HDTV, then the pixel density at the distance is still true? Especially considering our field of vision, which varies...? The iPhone's "retina display" is considered that only if it's about 3 feet from your face.

pixel density is a quality of the screen (based on screen size and resolution). there might be a measure of perceived pixel density (not that i know of), but a person's ablity to see the pixels does not change whether they are there or not.

I wish for a phone that is rechargeable by sunlight . . .

Even if you keep the main recharge system, having a support of solar would be great. But it would make the phone much larger.

The 4S came out LITERALLY 3 days ago, and already we've come full circle with the iP5 rumors...

lol that's how it works at cell phone websites. Hell there were already iphone 5 rumors before they even announced the 4S.

i agree. Not really feeling the fact that these rumors are out. The funny part is i am already thinking about buying this phone

This is non sensical. Why are they already making speculations about the next gen iPhone, couple weeks after the 4s was announced? Total bullS..

Whats the point of a screen resolution higher than the human eye can see? Are they trying to market the phone for robots or something?
