The next wave of quantum dot technology could finally bring consumer TVs closer to the full Rec.2020 colour gamut used in modern HDR formats like HDR10+ and Dolby Vision.

Perovskite quantum dots (P-QDs), emerging as third-generation quantum dots, promise colour reproduction beyond today’s QD-OLED and LCD displays.

While current QLED and miniLED TVs using second-generation indium-based quantum dots cover roughly 75% of Rec.2020, P-QDs could exceed 95%, potentially outperforming both QD-OLEDs (85–90%) and the upcoming RGB LED LCDs (around 90%).

Quantum dots enhance display colour by converting blue LED light into red and green.

First-generation cadmium-based dots have been largely phased out due to toxicity concerns, while indium-based dots have limitations in colour purity.
