China-based QD developer Zhijing Nanotech demonstrated its perovskite-QD film (PQDF) at Displayweek 2018. The company showcased a 55" LCD TV that uses the film to convert the blue LED color to a white background.

Zhijing Nanotech says that its low-cost PQDF can be used to achieve a high 110%+ NTSC color gamut and a high efficiency.
