To be fair, Sony's Trinitron screens were amazing, and in some regards LCD screens are still worse than CRTs.
Seems the next step from QLED and OLED is to move to MicroLED, which is not to be confused with Mini LED. Hopefully, MicroLED will prove to be financially viable, have fewer issues than OLED and deliver in its low latency promises. That said, it will take a long time before MicroLEDs to be ready for consumer-grade products.
As far as Samsung goes, I think they may have backed the wrong horse by sticking to QLED (and not backing OLED). The per-pixel lighting nature of OLED is a huge advantage, and it is causing a lot of people to favour LG's screens. Even the name QLED makes me think that Samsung wanted it to look like OLED as much as they could.
