It’s not irrelevant to the conversation, when your the one who tried arguing it in the first place. Like I’m not an expert in quantum physics, but we’re talking about TV’s here man, hardly a complex subject, but you tried to come out like an expert, and then argued this

OP - “QLED” is a backlit LCD technology (True)

AadamAtonic - “No it's not LED is self lit, like pixel led lights.... (False when talking about TV’s/display technologies). LCD is "liquid crystal display" and needs back light shined onto it.

You are correct that Samsung has something even higher quality than that though, but it won't become standard for 10 years or so. It's not even on the main market yet.”

That was wrong bro, just admit it. Even changing your sentence to OLED from LED still makes it wrong.
