The HTC One is built around a 5-inch, full HD 1,920 x 1,080 display with a pixel density of 441 ppi. That's identical to the Samsung Galaxy S4. The 4-inch Retina panel on iPhone 5s puts out 1,136 x 640, or 326 ppi. Let's face it, they're both really nice to look at. But HTC's is bigger and that means more pixels. HTC protects its display with Gorilla Glass 3; Apple protects the 5s from fingerprints.
