Same here, working with and in that industry for ~17 years on technology strategy. I'm no evangelist either, neither for LCD nor OLED. I frankly don't know how you technically define "visible burn-in" in context of QD (do you mean actual pure QD tech or Samsungs mixed use of the tech for QLED TVs?). If we can agree, that: 1.) The jargon "burn-in" on OLED describes the luminance degradation of individual sub-pixels (i.e. a weaker red because the operation hours of a red sub-pixel were much higher than its neighbours). 2.) Samsung's "QLED" is a brand for a LCD panel with the backlight created using R/G QD and blue LED (instead of blue/yellow LED). The backlight on standard QLED is separated in ~700 zones of the display, so you have huge clusters of pixels using the same backlight zone. Then: What is the equal meaning of "burn-in" then in the context of QLED? The luminance degradation of the whole zone? Or is it the "legacy" meaning of burn-in on LCD: The occurence of weaker/dead pixels due to issues in the TFT layer (broken/weak transistors no longer properly rotating the crystals)? Either way, I can't confirm and don't agree that OLED TVs will see a visible "burn-in" after ~2000hrs of normal use. First-gen models yes, but definitely not currently shipping models.
