3. Graphics > Retina Display

Retina Display

Apple released the iPhone 4 in June of 2010 and with it came a brand new display technology. The screen was the same 3.5 inch size as previous generations but they managed to quadruple the number of pixels used on the screen. The previous iPhone had a 320×480 display at 163 ppi (pixels per inch). The iPhone 4 has a 960×640 display at 326 ppi. Apple calls the technology Retina Display because they claim the display has higher detail than the human eye can perceive. There has been a lot of discussion whether that statement was marketing fluff or not, but at the end of the day no one can deny the display looks amazing, especially when comparing it to older devices. Regardless of how Apple marketed their new display, it was very clear why they went this route and it was really App Store focused.
