While other smartphone vendors have also released smartphones with AMOLED displays, the S4 has the highest resolution so far, with a pixelformat of 1, 920 by 1, 080, IHS senior analyst Vincent Leung explained in a note released Tuesday morning.
With the iPhone 5, Apple is expected to move to a larger display size, at about 4.0 inches diagonally, as opposed to 3.5 inches for the previous models, including the iPhone 4S. The pixelformat will likely increase to 1, 136 by 640 pixels, up from 960 by 640 for the iPhone 4S, maintaining 326 pixels per inch resolution.
