Quantum dots (QDs) have already been shown to achieve >90% BT.2020 color gamut in LCD displays using (QDEF®) Quantum Dot Film technology. In this paper, we report that by further engineering of the quantum dot materials, >90% BT.2020 is possible in a RoHS‐compliant package. This is possible by using a combination of cadmium‐free and low‐cadmium quantum dots.

Quantum‐dot enhancement film (QDEF) is giving LCD technology an edge as it battles new TV display entrants such as white organic light‐emitting diodes (WOLEDs). Recent advances in quantum‐dot properties are also enabling new and innovative implementations. This includes their evolving use in LCDs, their possible deployment in OLED and microLED displays, and their potential as emitter materials for future printable electroluminescent displays.
