The most important feature on any iPad is the screen. So for the iPad with Retina display, we wanted to build not just the best iPad display, but the best display on any mobile device. To create a display with over 3 million pixels was an engineering feat in its own right. But we went even further. We designed a camera that could take images as brilliant as the display itself. And we enclosed iPad in a unibody so thin and light, you can take all those pixels with you wherever you go. And they travel beautifully.
In order to create a display with a 2048-by-1536-pixel resolution, we had to design it in a completely new way. Every pixel in a display has multiple signals telling it when to light up. But when you have a lot of pixels and a lot of signals on the same plane, signals get crossed and image quality suffers. To make sure everything on iPad looks crystal clear, Apple engineers elevated the pixels onto a different plane — separating them from the signals. It’s technology that’s breakthrough. Just like iPad itself.
