I'm talking about QD films, not diodes.

Since early 2010s Vizio, HiSense and TCL made TV with 3M's QDEF [1].

This year, a few brands made TVs with perovskite quantum dot film. They are being branded as QLED.

The widespread adoption of Rec. 2020 creates a demand for displays capable of displaying larger color volume. Phosphor LEDs TVs have around 60% coverage of Rec. 2020. The best OLED TV has 73% coverage. QDEF TVs has up to 81% coverage. The perovskite quantum are capable of achieving more than 90% (but the commercially available TVs are not there yet).

> ok, so in TVs

No idea why there isn't any computer display with QDEF. It is probably easy to convert them using a filter from a old TV. However, But, this is probably not a good idea, those old quantum dots were toxic.

I think QLED will be everywhere.
