Apple describes IPhone4’s Retina Display as
“The sharpest, most vibrant, and highest-resolution phone screen ever”
Yes! Absolutely agreed
Well Friends Retina Display is truly a care for our eyes.
But a general question, “What the hell is Retina Display?”
Our eyes are capable of viewing details till 300 PPI (Pixel Per Inch or Pixel Density). But 300 PPI is completely dependent on distance between source (eye) and the destination (image). Now, Apple smartly played their cards and provided IP4’s Retina Display that has 326 Pixels Per Inch (i.e. 326 PPI). So no matter at what size your text, WebPages, images bla bla bla… your content is Sharp, Crisp and Crystal Clear
This will make you understand in much better way
The Problem with earlier IPhones was that, if we view our Iphone from side angles we will see that its Display gets manipulated i.e. there is a change in its contrast, color, brightness etc…
But IPhone 4 looks very good no matter at what angles we are viewing them.
It’s still Brilliant.
This Leap in Technology is due to 326PPI Retina Display
