I'm nota techie, so don't understand exactly how it works. This what I understand: OLED stands for Organic Light Emitting Diode. Each pixel produces a colour AND its own light, or none. This means total black, the basis of TV brightness.. There is no back light.
Samsung's reply is QLED; Quantum Dot Light Emitting Diode. I bought a 55 inch TCL QLED on Ebay for $1400; Android Smart TV, UHD 4K, and it's terrific. Don't understand how it works
QLED is NOT a new display system as far as I can tell. It is still essentially an LCD TV with a backlight. (which the OLED doesn't have)
Now I've had it for awhile ,and done some comparisons, I'm left with the impression that what I bought is simply a very good LCD TV. That I fell for hyperbole.
Be most interest in opinions about the QLED TV .
Sounds like fancy language to get more money out of you. I paid $200 for mine I think it is only 45, and it works fine.
Just like calling fish eggs caviar makes you more money.
I have no problem with supply and demand, or new inventions making human's lives better. And I don't have a problem with price differences or even quality differences, to some extent. But the reality increasingly with global marketing, it isn't about problem solving, but gaining shareholders. Cheap products are simply made to be thrown away. Problem is they don't last long, and that produces more pollution worldwide. The problem with "luxury" items, is that the more they charge for those things, the more it prices everyone else out of affordable living because that drives the makers of the cheaper stuff to charge more too.
Marketing works, otherwise businesses wouldn't us it. The real problem globally is that you have 62 uber billionaires in the world that have the combined wealth of 3 billion of the rest of the planet.
