It’s the Low-Temperature Polycrystalline Oxide (LTPO) that allows the refresh rate to be variable based on the content on the screen. For example, if your phone’s display refreshes at 120Hz constantly, that would consume too much battery life. But with the LTPO display, the refresh rate drops as low as 1Hz when the content on the screen is static, like when you’re viewing an email or text message. The 120Hz rate (which means that the screen is redrawn 120 times each second) is seen when gaming, viewing high-resolution video, and when you’re scrolling through apps and websites.
As is Apple’s wont, it will give the iPhone 18 Pro and iPhone 18 Pro Max a new feature to set it apart from the iPhone 18 and iPhone 18 Air. Normally we’d say that this will be done to attract consumers to the more expensive models but if the rumors are right, the most expensive iPhone model next year will be the ultra-slim iPhone 17 Air even though it will be out-spec’d by the iPhone 17 Pro models. We will just have to wait and see.
