10Hz~120Hz variable refresh rate display’Galaxy Note 20 Ultra’ for the first time

An OLED display applied with 10Hz~120Hz variable refresh rate technology was first mounted on the’Galaxy Note 20 Ultra’.

‘Adaptive Frequency’, a low-power OLED technology developed by Samsung Display, is characterized by lowering the panel drive power by up to 22% compared to existing smartphones in everyday use environments.

For example, in a 5G environment, it supports a variable refresh rate of 120Hz for mobile games that require fast screen switching, 60Hz for movies, 30Hz for general text checking and input such as email, and 10Hz for still images such as photos and SNS.

Existing smartphone panels generally use a fixed refresh rate, making it impossible to change the refresh rate according to the content. This is because the luminance changes and flicker occurs when driving at a low refresh rate.

Samsung Display explained that it applied a new backplane2) technology to effectively control the flicker caused by low refresh rate driving, and through this, it was the first to implement a ’10Hz’ refresh rate in a smartphone.

In particular, when using still images such as photos and SNS, the panel drive power was reduced by up to 60% by using a low scan rate of ’10Hz’. Existing panels used the same refresh rate regardless of content, resulting in unnecessary power consumption.

Samsung Display said, “In the future,’Adaptive Frequency’ technology will be expanded and applied to various IT products including smartphones. In addition, we plan to strengthen technology development by increasing material efficiency and optimizing driving parts to reduce power consumption.” Revealed.
