According to the Korean website the elec, two of the four iPhone 13 models to be launched next year (presumably Pro) will use low-power ltpo OLED displays, paving the way for a 120Hz refresh rate.Samsung and LG will remain the main suppliers of Apple's OLED displays, which are expected to be used throughout the iPhone 13 series, and Chinese manufacturer BOE aims to win some orders, the report said.
Ltpo technology will lead to a more power-saving backplane, which is responsible for turning on and off individual pixels on the display. This, in turn, achieves a refresh rate of 120Hz, resulting in smoother scrolling, smoother motion, and higher response speed. Similar to the apple watch series 5 and series 6 models, ltpo allows the iPhone 13 to have a always on display and help extend battery life.
Although there are rumors that the iPhone 12 Pro will support a refresh rate of 120Hz, Ross young, a display industry analyst, accurately claims that this is not the case, pointing out that the feature will be added with ltpo in 2021.
