The New Trend Of Organic Light-emitting Diodes
Mar 15, 2021
In 2009, Professor Adachi from Kyushu University in Japan introduced thermally activated delayed fluorescence (TADF) materials into OLEDs for the first time.
This type of material has a very low single triplet energy gap and can achieve 100% theoretical internal quantum efficiency through the reverse intersystem crossing of triplet excitons (RISC). The material system and device structure are becoming more and more perfect, making OLED stand out in the display field.
On the other hand, WOLED has a series of advantages such as high luminous efficiency, adjustable spectrum, less blue light component and surface light source. As a high-efficiency light source with low color temperature and no blue hazard, it is expected to become a new trend of healthy lighting in the future.
