Korean Researcher Increases the Efficiency of OLEDs Up To 75%

A group of Korean researchers from the KAIST (Korea Advanced Institute of Science and Technology) has find out a new way by which the OLED products including OLED TVs can be made more efficient. Prof. Kyung Choel Choi has led the team.

The researchers have worked on the idea of using surface plasmon. For localization of the surface plasmon, silver nanoparticles were deposited thermally on cathode in a vacuum.

A high level of oscillator decay is caused by the plasmons. And because of this the time determined photoluminescence fall out showed an increase of emission rate up to 75% while the PL continuous wave results displayed the intensity to be doubly enhanced.

The Korean research team’s attempt to improve the OLED efficiency is highly significant as many leading companies who are willing to produce the advanced OLED TVs. This new method discovered by the Korean team is applicable on the flexible OLED devices as well.
