Retina display

01 Mar 2011

The Retina display refers to screen technology introduced by Apple in the iPhone 4.

It features a 960 x 640 resolution, an 800:1 contrast ratio and four times the number of pixels than earlier iPhone models.

The iPhone 4 Retina display also uses IPS (in-plane switching) technology, which is also found in Apple LED Cinema Display and iPad - to achieve a wider viewing angle than on typical LCDs.

It also has an ambient light sensor that adjusts the brightness of the screen for optimal viewing and battery life.
