Biomimicry (emulating designs and ideas found in nature), which is a design approach used by many companies today, really works.

According to the research result published in the journal Nano Letters, Korean scientists have significantly improved OLED performance by imitating the nanostructures of fireflies.

Fireflies are the most efficient and brightest among them, compared to bioluminescent insects. By imitating this situation of fireflies with asymmetric microstructures and longitudinal nanostructures, OLEDs were produced by polymeric organosilicon compound PDMS (polydimethylsiloxane).

In this way, with the innovative solution inspired by nature, External Quantum Efficiency of OLEDs was increased by 61 percent.

In addition, thanks to the super Lambertian reflectance (ideal diffusely reflecting surface), the viewing angle has also been extended.

Korean scientists, who also add OLED technology to innovative solutions obtained by imitating nature, seem to add strength to the power of leading companies in panel production.
