New Samsung technology increases smartphone power savings
Samsung Display Company, a global leader in design and making of LCD and OLED display panels, has revealed a new technology that increases smartphone power savings by as much as 22 percent.
The new low-power OLED adaptive frequency technology is being commercialized for the first time in Galaxy Note20 Ultra 5G flagship smartphones.
Ho-Jung Lee, vice president of the mobile display product planning team for Samsung Display, said in a press release, ” High-definition video streaming and gaming are expanding their capabilities in line with 5G commercialization, creating a widespread need for display panel technologies that can enable greater power savings.”
He added, “Our Adaptive Frequency display technology is expected to considerably enhance the user experience by calibrating refresh rates in line with the requirements of a specific application and therein more precisely allocating available power. This will free up time for other smartphone operations.”
The technology supports a 120Hz scan rate for playing mobile games that require speedy frame changes. It also supports a 30Hz rate for email correspondence, a 60Hz rate for movie streaming and a 10Hz rate for browsing social networking services or viewing photos.
Modern phone panels have a fixed refresh rate, which cannot be automatically calibrated by the panels. This would cause image flickering as a result of luminance differences at lower refresh rates. The new backplane** technology by Samsung Display gets rid of flickering for operating frequencies as low as 10Hz.
To be specific, when viewing photos, the new variable-rate panel has proven to save 60 percent of operating power by introducing a low-frequency refresh rate of 10Hz. It should be noted here that traditional panels waste power by using a consistent, fixed frequency regardless of the content type.
