The iPhone 4 Retina display uses technology called IPS (in-plane switching) — the same technology used in the Apple LED Cinema Display and iPad — to achieve a wider viewing angle than on typical LCDs. Which means you can hold iPhone 4 almost any way you want and still get a brilliant picture. That’s perfect when you’re sharing photos with a friend or moving your iPhone round while playing a driving or flying game. In addition, the Retina display offers four times the contrast ratio of previous models, so whites are brighter, blacks are darker and everything is more beautiful.
