Retina Display
Retina Display is a marketing term developed by Apple to refer to devices and monitors that have a resolution and pixel density so high – roughly 300 or more pixels per inch – that a person is unable to discern the individual pixels at a normal viewing distance. Apple’s Retina Display made its debut on 2011’s iPhone 4S, which featured a 960×640 pixel screen with four times the number of pixels (326 pixels per inch) as the iPhone 4.
The new iPad that was released in early 2012 included a 2048×1536 resolution Retina Display as well. The 2012 lines of updated Mac Book Pro and Mac Book Air notebooks are expected to include Retina Display screens with 2880×1800 resolution displays. Intel is also expected to help make Retina Display a reality in laptops and Windows 8 tablets and ultrabooks with its new Ivy Bridge processor architecture.
