The Retina display doubles the pixel display for the iPhone screen. The display has been increased to 326 pixels per inch. The previous iPhones offered 160 ppi, and the iPad slightly lower at 132. The added resolution amounts to a 960x640 display, or four times the current iPhone. Interestingly, the iPhone 4 has the 78-percent of the pixels as the much larger iPad. The new display also offers an 800:1 contrast ration, again 4x better, and uses IPS technology like the iPad. Looking for more iPhone 4 videos? Check out my iPhone 4 playlist: www.youtube.com
