This new screen, first debuting on the Galaxy Note20 Ultra 5G, can hit 120Hz when high gaming rates are needed, drop to 60Hz for video playback, 30Hz when messaging or as low as 10Hz when displaying an image quiet.
At the slowest setting, Samsung claims it can use only 60 percent of the power normally required, while other screens cannot be adjusted without starting to turn on. Samsung Display VP mobile display planning Ho-Jung Lee said in a statement “Our adaptive frequency display technology is expected to significantly improve the user experience by calibrating the refresh rates according to the requirements of a specific application and thus by specify the distribution of available energy. “
Overall, the company claims that its technology can save up to 22 percent energy compared to other screens. However, as AnandTech emphasizes, it is not clear how granular control can be, or whether it is limited to the specified settings. We’ve seen adaptive synchronization technology on monitors and even TVs used to reduce dizziness, but on these small screens at least the first implementation is primarily about saving energy.
