According to Macrumors , sources from The Elec indicate that all four versions of the iPhone 17 will use LTPO OLED display panels. This means that the standard iPhone 17 models will also feature 120Hz ProMotion display technology and Always-on Display, similar to the Pro versions.

Currently, the iPhone 15 and iPhone 15 Plus use low-temperature polycrystalline silicon (LTPS) panels, while the iPhone 15 Pro models use the more advanced LTPO polycrystalline oxide (LTPO) panels.

LTPO panels support ProMotion, allowing the display to increase refresh rates up to 120Hz for smoother scrolling and video viewing when needed.

ProMotion also allows the display to reduce its power-saving refresh rate to 1Hz. This helps the iPhone 15 Pro display the clock, widgets, notifications, and lock screen wallpaper even when the device is locked.

Apple is expected to continue using the less advanced LTPS panel for this year's iPhone 16 and iPhone 16 Plus to maintain the differentiation between the standard and "Pro" models. Thus, Apple's 2025 iPhone lineup will for the first time feature ProMotion and always-on displays on both the standard and premium versions.
