Graphene-Based OLED Displays Invented in South Korea

OLED Displays Invented in South Korea

Apparently, Korean researchers have made a huge step in display technology. The scientists from South Korean Electronics and Telecommunications Institute became the first to create OLED displays based on graphene. Considering amazing properties of this material, such displays will be super-thin and flexible. More than just flexible – it will be possible to sew them into clothes and integrate into wearable devices.

Many scientists in the world experiment with graphene trying to invent something innovative. Koreans decided to rethink the current OLED technology and succeeded. The scientists managed to completely replace ITO (indium tin oxide) electrodes with their equivalents made of graphene. The replacement can be easily explained: graphene electrodes aren’t as fragile as ITO electrodes and they are much more flexible.

The technology has already been tested on an experimental display (370x470mm). The graphene electrodes were only 5nm thick.

The scientists have huge plans for the future. They made considerable progress compared to the last year, so we might expect big things in 2018. In fact, Koreans plan to show translucent plastic OLED electrodes along with first fully wrappable displays suitable for household use.
