The S21 Ultra serves as the debut device for Samsung’s new low-power OLED display technology. The tech giant has revealed that the flagship phone makes use of an OLED display that reduces power consumption by up to 16 percent.
The company made mention of how the device’s screen supports refresh rates of 120Hz at both full HD and Quad HD resolutions but kept this as a surprise to its users. Samsung found a way to make electrons flow faster across its OLED’s organic layers, and the company says that allows the display to “create brighter light while consuming less power.”
Increasing phone battery capacity has a limit and that’s why phone making companies have to think of ways to make their devices more power-efficient. Samsung explains that the display panel is “one of the most important components affecting a smartphone’s total power consumption.”
