How come the addition of the extra pixels on the new iphone screen doesnt affect the dpi count and "retina mode"?
 
How come the addition of the extra pixels on the new iphone screen doesnt affect the dpi count and "retina mode"?

The number of extra pixels is directly proportional to the increase in surface area. Therefore no change in dpi count.
 
The term Retina is describes a certain density/size of the pixels. The new iPhone still has the same pixel size/density but a larger screen so more of the same sized pixels.
 
Because they added the exact amount of extra pixels needed.

Think of it this way: They put the same old 4S retina screen in the middle of the phone and then added a smal retina strip on top and a small retina strip on the bottom.

That's not literally how they do it, but that's the basic theory. The DPI has not changed.
 
The screen is 1136-by-640-pixel resolution at 326 ppi
Still retina 326 just like the 4s
