Apple needs a way to showcase the sharp, colorful display on the iPhone X. It can’t just rely on apps, games, and videos. The moment someone turns on the phone he or she should be greeted with a best-in-class display. Fortunately Apple thought of that, and the very simple implementation leaked.

The $999 device is Apple’s first to ship with an OLED display. While countless phones from the Android side have shipped with the technology for years, this is the first time we’re seeing it from Apple-branded hardware. The company is paying Samsung a massive amount of money to create custom panels for the iPhone X, so Apple is in good hands. Samsung’s Galaxy S8 and Galaxy Note 8 have been praised for having the year’s best displays.

Dynamic wallpapers are the way Apple intends to proudly show-off the sharp, colorful display on the iPhone X.

The iPhone 8 and its predecessors ship with wallpapers featuring colored backgrounds behind floating circles. Apple will take them a step further for the iPhone X. The colored backgrounds will be switched to black while the floating circles gain color. So the OLED display should make the black seem immersive and have the colored floating circles really pop.

There will be seven of these special dynamic wallpapers on the soon-to-be-released iPhone, according to Benjamin Gaskin. He shared a screenshot of the library on Twitter, and it reveals all the choices. Some are similar to the original versions of the dynamic wallpapers, but Apple did switch colors around for a few.

Original versions of dynamic wallpapers on previous iPhones do appear to have been removed.

Apple will begin taking pre-orders for the iPhone X on October 27, and you can check out this list of tips we put together to help you get your hands on one.
