A:Answer Burn in problem may be an "Urban Legend" for OLED displays. Since each pixel is a discrete light source, it would require the light source to be "on" to some degree. The screen is so "black" that if I turn all of the lights off in the room at night, I can't tell that the TV is even on, unless the small red LED at the bottom of the TV is in view.
However in the picture menu is an option to "Clear panel noise". That makes sense to me since there may be a "confused" pixel after having the TV on for extended periods of time. None of the OLED TVs on display have any signs of burn in, so I am not concerned and very happy with my purchase.
To further dispel any burn-in rumors, if OLED burn in was a problem, I believe we would have more evidence from all of the cell phones which now use OLED screens. When I think of burn-in, I think of the early 2000's with plasma TVs and LCD technologies.
I am VERY happy with my purchase.
