Water repellent spray-type encapsulation of quantum dot light-emitting diodes using super-hydrophobic self-assembled nanoparticles

- A spray-type encapsulation method capable of being applied to flexible and concave/convex substrates has been demonstrated to have no negative effect on the luminance and efficiency of QD-LEDs.
- The highly dense thin-film provided by SAM-NP encapsulation can increase the effective lifetime of QD-LED devices by a factor of 16.
- The QD-LEDs with SAM-NP encapsulation were found to have an effective lifetime in ambient air and a stable light emission in water.
