Abstract

Monodisperse quantum dots (QDs) were prepared by low-temperature process. The remarkable narrow emission peak of the QDs helps the liquid crystal displays (LCD) and electroluminescence displays (QD light-emitting diode, QLED) to generate wide color gamut performance. The range of the color gamut for QD light-converting device (QLCD) is controlled by both the QDs and color filters (CFs) in LCD, and for QLED, the optimized color gamut is dominated by QD materials.

Keywords: Color filter (CF); Quantum dot light-converting device (QLCD); Quantum dot light-emitting diode (QLED); Quantum dots (QDs); Solution process; Wide color gamut.
