Apple’s recent upgrade to the Apple Watch Series 10 introduced new display technology with significant implications for future iPhone displays. The Series 10 display uses LTPO3, a low-temperature polycrystalline oxide thin-film transistor, enabling ultra-efficient dynamic refresh rates. This marks an evolution from the previous LTPO2, which supported refresh rates from 1Hz to 120Hz for always-on functionality. LTPO3 promises better power efficiency, even broader refresh rate potential, and opens the door to higher rates that could enhance future devices.
According to industry reports, Apple’s long-time supplier, Samsung Display, is working on integrating LTPO3 technology into displays for the upcoming Apple Watch Series 11. This collaboration could prime Samsung to eventually apply LTPO3 advancements to iPhone screens. If realized, this could mean an upgraded ProMotion display for future iPhone models, with potential refresh rates of up to 240Hz—a capability already featured in some high-end Android devices.
The anticipated ProMotion boost would bring noticeably smoother scrolling and improved responsiveness to iPhones, enhancing the experience for gaming, video, and everyday use. For now, Apple fans are left waiting to see if this advanced LTPO tech will indeed make its way into the iPhone lineup in the coming years.
