What is "dpi"?

Dots per inch (dpi) is a measure of a display's pixel density, and is defined as the number of individual pixels that can be found in a 1-inch line. Apple defines smartphone-based Retina displays as having a 300dpi or greater rating. The company claims that tablets can make due with less densely packed pixels and still earn a Retina badge since tablets are held further from the user's eyes.
