Scientists produce full-color flexible microLEDs using perovskite QDs
- Researchers from Korea's KIMM institute have actually produced full-color flexible microLED devices, using blue LEDs as well as perovskite quantum dot color conversion layers.
The demonstrated device featured 1 mm pixel pitch LEDs (25.4 PPI) and also could be bent with a radius of 5 mm without being harmed.
The researchers used a perovskite-QD and siloxane compound using ligand traded PQD with silane composite adhered to by surface activation by an enhancement of halide-anion consisting of salt. As a result of this surface activation, the scientists say that it was possible to create the PQD surface area with a silane ligand using a non-polar organic solvent that does not harm the PQD. Therefore, the ligand-exchanged PQD with a silane compound exhibited high dispersibility in the siloxane matrix and excellent atmospheric security.
