Abstract

Quantum dots (QDs)-based backlight greatly enhances the color performance for liquid crystal displays (LCDs). In this review paper, we start with a brief introduction of QD backlight, and then present a systematic photometric approach to reveal the remarkable advantages of QD backlight over white LED, such as much wider color gamut, higher optical efficiency, enhanced ambient contrast ratio, and smaller color shift. Some popular LC modes are investigated, including twisted nematic, fringing field switching (FFS) for touch panels, multi-domain vertical alignment (MVA) for TVs, and blue phase liquid crystal (BPLC) for next-generation displays. Especially, QD-enhanced BPLC combines the major advantages of FFS and submillisecond response time. It has potential to become a unified display solution.
