Researchers use a high-output flexible QD-OLED patch to encourage hair growth | OLED-Info

Researchers at Korea's Gachon University, in collaboration with InnoQD and researchers from Chungbuk National University, have developed a new QD-OLED patch that can encourage hair growth. The patch can also measure heart rate at the same time.

The researchers used a flexible OLED device, and covered it with quantum dots that emit near-infrared (NIR) light. The OLED device is a tandem blue OLED device, that offers a high light output. The researchers say that when attached to the head, the patch encourages hair collicle cell growth, with a measured improvement of 23% in hair growth.
