#6 – New Retina HD Displays
The iPhone 6 has a new Retina HD display, which is made of ion-strengthened glass. The display has better viewing angles, and is easier to use in direct sunlight. The iPhone 6 features a resolution of 1344 x 750 pixels, which means it kept the same 326 ppi as the iPhone 5/5s, but it has a better resolution thanks to the larger screen. On the other hand, the Plus has a full HD screen with a resolution of 1920 x 1080 pixels, which equates to 401 ppi.
