Samsung Display panel adapts refresh rate to different tasks

Samsung Galaxy Note 20 Ultra is the first smartphone to feature Samsung Display's backplane display technology that has a variable refresh rate, the company announced on Wednesday. Other customers will be able to purchase the Galaxy Note 20 or Galaxy Note 20 Ultra in the country starting August 28. A higher refresh rate allows it to feel more responsive using a pen or playing mobile games and scroll even more smoothly, but as people with 90Hz phones have learned, it can also put more strain on the battery. However, higher refresh rate displays also drastically increase power draw.

The Galaxy Note Ultra 5G is the primary telephone with this OLED screen. Still, Samsung's low-power OLED adaptive frequency technology appears to work in a similar manner, and a dynamic refresh rate should certainly be a welcome feature for users. It is, however, the first time this tech has been deployed on smartphones. Samsung Display's new backplane** technology eliminates flickering for operating frequencies as low as 10Hz.


Some of the current generation high-end smartphones do offer the ability to switch between different refresh rates. As a result, the display draws the same amount of power regardless of the type of content it is showing.

Samsung Display, a display affiliate of Samsung Electronics, has commercialized a new power-saving function for displays called adaptive frequency.


Moreover, when in 10Hz mode, the display draws just about 60 percent of the operating power of existing display technologies. The technology is created to cut the operating power of an organic light-emitting diode (OLED) display by as much as 22 percent, according to Samsung Display, by applying varying refresh rates depending on usage instead of adopting a unilateral rate. The Samsung Galaxy Note 20 Ultra comes with up to 120Hz refresh rate. Expect the South Korean giant to use this ground-breaking technology in more of its products in the future.
