A:Answer You would buy this instead of an OLED if its going to be in a bright room and you are worried about burn in. OLEDs can get burn in if you watch a bunch of news shows or play games for hours a day. If its going to be running for 10+ hours a day then safer to get a QLED. Basically, after a few months of use a game HUD or news ticker bar would be burned into the TV and persist through other images.
This TV is close to OLED, not quite there yet but it does show black with other content on the TV and its able to turn sections of the TV off to show better blacks. That's why you buy a Full Array Local Dimming TV instead of Edge Lit.
