F-VLEDs Reduce Heat Generation, Opening Way for Biomedical Applications

Facebook Twitter LinkedIn Email Comments
Flexible vertical micro-LEDs (f-VLEDs) have been developed using anisotropic conductive film (ACF)-based transfer and interconnection technology. Thermal reliability and lifetime were improved by reducing heat generation within the thin film LEDs. Researchers from the Korea Advanced Institute of Science and Technology (KAIST) fabricated a f-VLED array using simultaneous transfer and interconnection, which was possible through the precise alignment of an ACF bonding process. These f-VLEDs, which were 5-µm thick and less than 80-µm large, achieved an optical power density about...Read full article
