Highly Stable White Light-Emitting Diodes Based on Quantum-Dots Dispersed Into the Backlight Lens for Display Backlight
A novel package structure has been developed to fabricate quantum-dot (QD) white light-emitting diodes (WLEDs) by dispersing QDs into the backlight lens and integrating them with blue light-emitting diode to form white light.For this in-lens encapsulation structure, the luminous efficiency and lifetime of QD-WLEDs can reach 90 lm/W and 1000 h, whic
