iPhone 13 Pro and iPhone 13 Pro Max are the first generation of Apple smartphones equipped with LTPO screens, with technology ProMotion has a refresh rate of up to 120 Hz. LTPO (Low-temperature polycrystalline oxide) is a display panel used on products equipped with high-end OLED screens, providing outstanding energy savings, but still ensuring display quality. The iPhone 14 Pro series is expected to continue to use this technology, but the refresh rate will be expanded.
Specifically, on the iPhone 13 Pro and Pro Max, Apple’s ProMotion display is limited to a refresh rate between 10Hz and 120Hz. This is in contrast to the LPTO panels used by Oppo and Samsung which can drop as low as 1Hz, when viewing still images or when the device is idle.
Screen analyst Ross Young said he is expecting the ProMotion screens used in the iPhone 14 Pro and iPhone 14 Pro Max to be capable of dropping to as low as 1Hz. This technology can help extend battery life and support always-on display mode.
Apple Watch Series 7 models use LTPO displays, allowing them to have the same 18 hours of battery life as previous Apple Watch models despite having an always-on display. Similar to Android phones equipped with LTPO, can display the time, date and any message on the screen at all times without unlocking the phone.
Last year, Bloomberg journalist Mark Gurman suggested Apple might bring similar functionality to the iPhone 13, but that didn’t happen. Currently, there are not many rumors indicating that the iPhone 14 Pro models come with the always-on display feature. However, that doesn’t mean Apple won’t surprise us. If the rumor turns out to be true, this will be a feature that makes it easier for iPhone users to track the time, date or notifications, helping Apple compete with Android rivals.
