Samsung Display Commercializes Refresh Rate Technology

Samsung Display Company has revealed new display technology that features a power-saving function for mobile electronics, being commercialized for the first time in Galaxy Note20 Ultra 5G flagship smartphones, the company said.

The display company has now successfully commercialized its low-power OLED adaptive frequency technology, which can curtail the operating power of a phone´s display by as much as 22 percent over existing smartphones now in general use.

The company´s power-saving technology allows the display panel to utilize variable refresh rates that consume the least possible amount of power for each type of application. The adaptive frequency technology supports a 120Hz scan rate for playing mobile games that require speedy frame changes, a 60Hz rate for movie streaming, a 30Hz rate for email correspondence, and a 10Hz rate for viewing still images or browsing social networking services.

Existing smartphone panels offer only a fixed refresh rate. They cannot automatically calibrate a phone´s refresh rate, which would result in image flickering caused by luminance differences at lower refresh rates. Samsung Display´s new backplane** technology eliminates flickering for operating frequencies as low as 10Hz.

In particular, when displaying still images, the new variable-rate panel has proven to consume operating power of as little as 60 percent by introducing a low-frequency refresh rate of 10Hz, while conventional panels unnecessarily waste power through the use of a consistent, fixed frequency regardless of the type of content.
