There are a lot of good articles about it. Explained in a rudimentary way, it's super hard to make good reds for LED and has been a problem since its inception. OLEDs use little organic red pixels and the blacks turn off all light instead of replicating a black. It's super interesting. When I was in school, they brought a major LED inventor to show us what they had, it wasn't good quality light at the time and for a long time afterwards. OLED was the first time I saw good reds. If you go to a costco, look at the difference between the reds on the same pic, can you tell there is a difference or does it all look sort of magenta? That's how you can tell if it's a good OLED or not. To be fair though, you can mess with the settings to make it look shitty which some stores do to sell more of a certain type of tv.
I'd be happy to read about it if you can point me in the right direction.

Wut
No light is emitted? Not sure how to clarify that for you. Instead of making a super dark blue, green, purple, etc., it turns out the light.
What exactly do you think black is?
Dude, explain it to me.
OLED pixels are self emissive, which means each pixel emits its own light. Normal LED screens need a backlight (usually coming in from the edges) so you get light bleeding into what should be black pixels. OLEDs just turn off the pixel entirely. Some new LED screens are starting to be fully backlit which eliminates the light bleed problem but they are not widespread yet.
