    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.
