Digital blogger @i Ice Universe recently tweeted that the Galaxy Note 20 Ultra uses the LTPO low-power screen. He says the galaxy Note 20 Ultra and Galaxy Z Fold 2 phones have minimum refresh rates of 1Hz, specifically, stills 1 to 11Hz, video 30 to 60Hz, and games 48 to 120Hz.
In fact, even before the launch, there were users on the XDA forum who broke the news that the Note 20 Series would feature ltPO low-power screens. LTPO is an acronym for Low Temperature Polycrystalline Oxide, Chinese called “cryogenic polycrystalline oxides.” Previously, on the Apple Watch Series 5, Apple addressed current power consumption issues in electronic devices by incorporating the features of the LTPS and IGZO solutions to introduce faster, but less power-consuming LTPO solutions.
This technology reduces the screen refresh rate to 1Hz, dramatically reducing power consumption, never holding a breath while ensuring battery life. If the use of LTPO backplane low-power OLED screen, then will greatly enhance the use of the experience, after all, playing games, brushing web pages, reading e-books and other operations, each scene of the refresh rate is not the same, certainly to save power is certainly of great help.
