With the iPhone 17 lineup, Apple plans to introduce a high-resolution LTPO (low-temperature polycrystalline oxide) screen. Compared to the previous iPhone series, which usually only offered high refresh rate displays on Pro versions, this is a major improvement.
Apple intends to outfit the whole iPhone 17 series with LTPO screens, a low-power backplane technology that enables variable refresh rate with lower battery consumption, according to a report from South Korea’s ETNews. Accordingly, ProMotion screens with a variable refresh rate of up to 120 Hz will be included in base versions.

Only the Pro versions typically have high refresh rate screens from Apple; even the most recent iPhone 16 and 16 Plus models only have 60Hz panels.
According to ETNews, LTPO screens from Samsung and LG, a premium Pro series technology that improves screen responsiveness and smoothness while using less battery, would be included in all iPhone 17 versions.
“Up until now, Samsung Display and LG Display have supplied all of Apple’s iPhone LTPO. Apple has also been sourcing OLEDs from Chinese display companies, but they have only entrusted some LTPS to them and not LTPO. Chinese companies are also having difficulties supplying LTPS panels due to quality issues occurring every year, so the general consensus is that it is realistically impossible for them to supply LTPO, which is more difficult to manufacture”
Over the past three years, Apple has added 120Hz ProMotion screens to its Pro iPhone models, enabling an always-on display. The iPhone 16 Plus boasts a bigger 6.7-inch display running at 60Hz, while the iPhone 16 sports a 6.1-inch Super Retina XDR OLED display. The Super Retina XDR OLED screens of the iPhone 16 Pro and iPhone 16 Pro Max measure 6.3 inches and 6.9 inches, respectively, and have a refresh rate of 120 Hz.

Previously, Ross Young of Display Supply Chain Consultants announced in September that all iPhone 17 models in the 2025 lineup will feature 120Hz ProMotion displays, including non-Pro versions.
According to reports, LG Display will make the panels for the Slim and Pro versions of the iPhone 17, while Samsung Display will make the panels for all models. Apple plans to replace the Plus model of the iPhone 17 series with a new “Slim” or “Air” model. Apple’s A19 Pro CPU will power the iPhone 17 Pro versions, while A18 or A19 chips with 8GB RAM may power the normal and Air variants.
