Samsung Display announced on Wednesday that it has adopted its Adaptive Frequency technology on the Galaxy Note20 Ultra that can save 22% more in panel power consumption.

Adaptive Frequency is the brand name given Samsung Display’s low-temperature polycrystalline oxide (LTPO) thin-film transistor (TFT) technology. It is a combination of the best qualities of low-temperature polycrystalline silicon (LTPS) TFT and oxide TFT. 

LTPO uses oxide to make the switching transistor on the TFT, which prevents electricity leaking. Use of the technology can save battery power consumption by 15% to 20%.

Samsung Display said Adaptive Frequency can save power consumption of OLED screens on 5G smartphones as it automatically controls the screen refresh rate.

Past panels had a fixed fresh rate which causes alterations in low refresh rate settings that caused flickers on screen.

Adaptive Frequency will support 120Hz for games, 60Hz for movies and 30Hz for text inputs and 10Hz for fixed images. Previous screens offered the same refresh rate even for low refresh rate images that caused unnecessary power consumption.

Samsung Display said it applied a new black plane technology to reduce flickers.

The company said it plans to apply Adaptive Frequency technology to more IT devices going forward.
