Tandem OLED

Tandem OLED is designed to achieve higher brightness and display efficiency. Under certain low‑luminance or low gray‑level conditions, the required driving current is relatively small and therefore more sensitive to subtle variations, which may result in fine granular non‑uniformity or slight brightness variation. In addition, when Dynamic Refresh Rate (DRR) is enabled, brief brightness changes may occur during refresh rate transitions.
These phenomena are related to driving characteristics at low luminance levels and refresh rate switching behavior, and are considered inherent characteristics of Tandem OLED technology. They typically do not have a noticeable impact on overall visual experience during normal use, such as video playback, web browsing, or high‑brightness content. Users who are more sensitive to brightness variation may disable the Dynamic Refresh Rate feature in system settings.
