The world's thinnest bendable OLED

The joint research group of the University of Tokyo in Japan and John Kepler University in Austria has developed the world's thinnest and lightest organic light-emitting diodes (OLEDs) that can be bent freely to a thickness of only 2 microns.

According to a report from the Japan News Service and other websites on the 29th, the research team successfully fabricated organic light-emitting diodes with a total thickness of 2 microns and a weight of only 3 grams per square meter on ultra-thin PET plastic films with a thickness of only 1.4 microns. It has good flexibility, and any bending will not affect its energization performance.

The research group had previously used ultra-thin polymer films to successfully develop ultra-thin organic solar cells and organic transistor integrated electronic circuits composed of carbon molecular materials. This new technology invention enables organic light-emitting diodes, organic solar cells and organic transistors to be integrated on the same polymer film, which is lighter and more practical than previous electronic devices.

Organic light-emitting diodes and organic solar cells are key projects in the field of material research and development in recent years and have entered a practical stage. Organic light-emitting diode display devices have the advantages of power saving, good color reproduction, and fast response speed, and are regarded as next-generation display materials. The demand for lightweight and ultra-thin electrodes has driven relevant technological advances.
