Realizing highly efficient quantum dot LEDs with metallic nanostructures at low cost

KAIST researchers have discovered a technology that enhances the efficiency of Quantum Dot LEDs. Professor Yong-Hoon Cho from the Department of Physics and his team succeeded in improving the efficiency of Quantum Dot (QD) Light-Emitting Diodes (LEDs) by designing metallic nanostructure substrates. QD LEDs possess very small semiconductor light sources and are considered to be the new rising technology for high performance full-color display. However, it is expensive to manufacture displays with QD LED only.
