Here comes the hyperbole. The Galaxy S III's screen is called the HD Super AMOLED. It measures 4.8-inches and has a resolution of 1,280 x 720. You know, fairly close to the resolution of a run-of-the-mill laptop panel. The pixels per inch (ppi) registers at 306. This panel is a PenTile display, meaning that the traditional RGB (red-green-blue) color pattern is supplanted by a RGBG pattern, which boosts its resolution but lends it a greenish hue. It's a trade-off worth taking into account.
The iPhone 5 comes to market with its first-ever screen size upgrade. The now 4-inch Retina Display has seen its resolution bumped to 1,136 x 640, retaining the same impressive 326 ppi as the iPhone 4S. Apple also improved the color saturation on its LCD panel. The glass itself is much thinner than before, allowing for the svelte build of the new device.
