Last year's iPhone 13 Pro is Apple's first smartphone equipped with a 120Hz promotion display. Although the two iPhone 14 Pro models will continue to use this technology, their screens are likely to have greater refresh rate changes this time In order to bring the promotion display screen to the iPhone 13 Pro model, Apple has adopted ltpo panel technology with variable refresh rate, which makes the backplane (the part responsible for opening and closing a single pixel) more power-saving.
In this way, promotion can dynamically generate a fast frame rate when users need it, and save battery when they don't need it.
However, in iPhone 13 pro and pro max, Apple The promotion display is limited to setting the screen refresh rate between 10Hz and 120Hz. This is in contrast to the lpto panel used by companies such as oppo and Samsung, which can reduce the refresh rate to 1Hz when viewing still images or when the device is inactive.
Rose young, a monitor industry analyst, said he "expects" the promotion monitor used by iPhone 14 pro and iPhone 14 Pro Max to fall to the same low point of 1Hz. Depending on how Apple decides, the technology could pave the way for longer battery life or continuously lit screen display elements.
For example, the apple watch 7 series models use an ltpo display, which enables them to have the same 18 hour battery life as earlier Apple watch models, despite a display that is always on. Similar to Android phones equipped with ltpo, the same technology on iPhone can display the time, date and any notice on the screen at any time without unlocking the phone.
Last year, Bloomberg reporter mark gurman suggested that Apple might bring similar features to the iPhone 13, but that didn't happen. At present, there is no reliable news that the iPhone 14 Pro model will be equipped with constant light display function. However, this does not mean that Apple will not surprise us. In fact, if Apple plans to expand the refresh rate change of its promotion display, there are currently no technical restrictions to prevent it.
