"Firstly, it uses environmentally friendly, cadmium free Quantum Dot technology, the most advanced technology that makes High Dynamic Range (HDR) more dynamic by enabling TVs to reproduce pure colors with lifelike brightness using cutting-edge nano-crystal technology. In addition, primary colors wavelengths delivered by Quantum Dot technology are narrow enough (around 40nm) to meet digital cinema color gamut at 93% of DCI-P3 color space."
