Only four months after LG installed 69 OLED TVs at Seoul's Incheon Airport it was reported that the TVs suffer serious permanent image-retention, or burn-in. ZDNet now reports that LG replaced the problematic OLED TVs at the airport's Korean Air Miler Club Lounge with LCDs.
The report suggests that LG was not sure it could solve the burn-in issues with this particular display, and so opted for an LCD. LG denies that burn-in is a serious issues and says the TVs's lifetime are over 30,000 hours.
I can personally say that I have a 55" LG OLEDB6 TV - which I bought in November 2016 (over a year and half ago) and it works great without any burn-in issues. It may be that the display at the airport was shown the same graphics all the time which is not a normal use case for TVs at home...
