We found that in our 20/7 Burn-In Test, the red sub-pixel is the fastest to degrade, followed by blue and then green. Our maximum brightness CNN TV has more severe burn-in than our 200 nits brightness CNN TV. LG has told us that they expect it to be cumulative, so static content, which is present for 30 minutes twice a day, is equivalent to one hour of static content once per day.

Note that we expect burn-in to depend on a few factors:

Those concerned about the risk of burn-in should go with an LCD TV for peace of mind. Those who display the same static content over long periods should consider the risk of burn-in, though (like those who watch lots of news, use the TV as a PC monitor, or play the same game with a bright static HUD). As a result, we don't expect most people who watch varied content without static areas to experience burn-in issues with an OLED TV. Long periods of static content have resulted in some permanent burn-in (see the CNN TVs) however, the other TVs with more varied content don't yet have noticeable uniformity issues on normal content.

Update : After more than 5000 hours, there has been no appreciable change to the brightness or color gamut of these TVs. Our stance remains the same: we don't expect most people who watch varied content without static areas to experience burn-in issues with an OLED TV. Uniformity issues have developed on the TVs displaying Football and FIFA 18 and are starting to develop on the TV displaying Live NBC. Update : The TVs have been running for over 9000 hours (around five years at 5 hours every day). If you have any suggestions of what you'd like us to test, let us know in the discussions below. We don't know just how resistant these new panels are to burn-in, but we're considering a next-generation burn-in test. OLED technology continues to improve, with innovations like LG's evo panels and Samsung's QD-OLED technology, which are likely to significantly reduce the likelihood of burn-in. Update : This test ended in November 2019.
