Next year’s iPhone 17 and iPhone 17 Plus will feature OLED displays with low-power back-panel technology, making ProMotion available for the first time on Apple’s standard iPhone models.

While the current iPhone 15 and iPhone 15 Plus use Low Temperature Polycrystalline Silicon (LTPS) panels, Apple’s iPhone 15 Pro models use more advanced Low Temperature Polycrystalline Oxide (LPTO) panels. LPTO panels support ProMotion, which allows the display to increase the refresh rate up to 120 Hz for smoother scrolling and video content when needed.

ProMotion also lets you reduce the energy-saving screen refresh rate to 1Hz; so iPhone 15 Pro displays have an always-on feature that shows the time, widgets, notifications, and wallpaper on the lock screen even when the device is locked.

Apple is expected to continue using less advanced LPTS panels in this year’s iPhone 16 and iPhone 16 Plus to maintain differentiation between the standard and Pro models. This means Apple’s 2025 iPhone lineup will be the first to feature ProMotion and always-on display. store

According to this ElectricChinese supplier BOE hopes to supply Apple with LPTO panels for the iPhone 17 series, but there are still questions about whether it can achieve the required production capacity while maintaining Apple’s quality control standards.

If BOE can’t meet the requirements, Apple will likely turn to other suppliers like Samsung and LG Display for LPTO panels and rely on BOE for LPTS-based OLED panels for older iPhone models and the rumored iPhone SE4.

According to display analyst Ross Young, this year’s iPhone 16 Pro models will feature a 19.6:9 aspect ratio, a change that will also apply to next year’s standard iPhone 17 models. The diagonals of the devices are expected to increase from 6.12 and 6.69 inches to 6.27 and 6.86 inches, respectively. This means a 2.5% increase in screen size on both devices.

Ultimately, this means the standard ‌iPhone‌ 17 models will get a major facelift with a larger bezel, LPTO for ProMotion, and an always-on display.
