White‐Light‐Emitting Diodes with Quantum Dot Color Converters for Display Backlights

Abstract

Highly luminescent, multiply passivated green- and red-light-emitting quantum dots are used as color converters in InGaN blue LEDs to achieve external quantum efficiencies of 72% and 34%, respectively. White QD-LEDs prepared for a display backlight are shown to have an efficacy of 41 lm W−1 and color reproducibility of 100% compared to the NTSC standard in CIE 1931. Finally, a 46 inch LCD TV panel (see image) using the QD-LED backlight is successfully demonstrated for the first time.
