Making a thinner, lighter iPhone meant even the display had to be thinner. Apple engineers accomplished that by creating the first Retina display with integrated touch technology. Which means instead of a separate layer of touch electrodes between display pixels, the pixels do double duty — acting as touch-sensing electrodes while displaying the image at the same time. With one less layer between you and what you see on iPhone 5, you experience more clarity than ever before. All on a display that’s 30 percent thinner than before.
