In the market for an iPhone? Here's a breakdown of all the currently shipping iPhones from Apple.
2020 iPhones Could Feature Fast 120Hz 'ProMotion' Displays
The leaker, who goes by the Twitter handle @UniverseIce, doesn't usually comment on Apple's plans, but is a well-regarded source of Samsung rumors. Samsung has supplied Apple with OLED panels for the iPhone X, iPhone XS, and iPhone XS Max.
Apple already uses variable refresh rate technology in its iPad Pro models, but they still use LCD panels rather than OLED. Bringing it to a new breed of OLED iPhones would raise the smartphone performance bar even higher.
Apple markets the iPad Pro-exclusive tech under the moniker "ProMotion," which it says dynamically adjusts the display to the movement of content for fluid scrolling, greater responsiveness, and smoother motion. It does all this on the fly, which means it also conserves battery life.
Apple's adaptive ProMotion IAPs also reduce Apple Pencil latency, and reliable Apple analyst Ming-Chi Kuo has said that Apple Pencil support is a possibility for a future iPhone.
Previous rumors have suggested Apple will complete its transition to an all-OLED iPhone lineup in 2020 with new 5.4-inch, 6.1-inch, and 6.7-inch devices.
But before 2020 comes around, Apple is widely expected to launch a trio of new iPhones this September, including two higher-end 5.8-inch and 6.5-inch OLED models and one lower-end 6.1-inch LCD model.
