Researchers Demonstrate RGB OLED LiFi

South Korean researchers have demonstrated a new approach to LiFi using a red, green, and blue (RGB) OLED array. The Pohang University of Science and Technology team utilized an organic photodiode (OPD) array as the receiver. Their study was published October 19, 2023, in the publication, Advanced Materials.

The new approach to LiFi reduced interference compared with broad white spectrum LiFi. The reduced interference improves stability and accuracy of the data transmission. OLEDs are commonly used in displays for TVs, smart phones, and laptops. OLED is also beginning to be used in automotive tail lights.

Initial demonstrations have been in a lab, but the researchers hope to move out of the lab to real-world conditions including competing light and dust. They also intend to test a moving transmitter in addition to a stationary one.
