OLED screens which Rtings is running at a low brightness or without showing content for any extended amount of time that has static image elements are running beyond 5,000 hours without evidence of permanent burn-in issues. There are inevitable qualifications to this number, based around how much you watch TV content with static image areas, how brightly you run the TV, and even the colors of the static picture elements (with OLED red seeming to degrade faster than other tones). The latest shot from Rtings excellent ongoing test for long-term screen burn-in issues on OLED TVs. The latest test, though, seems more sensible in its approach - and suggests that the latest OLED TVs can suffer with screen burn after as little as 4,000-5,000 hours of use. ![]() This is actually Rtings’ second stab at measuring how much of a problem screen burn on OLED TVs is, but I kind of dismissed the first one, as its methodology didn’t feel ‘real world’ enough. In fact, with such new anti-retention/anti-screen burn measures seeming to appear increasingly often in recent times when OLED TVs have been around for years, it’s hard not to think that the flurry of activity has something to do with the growing influence of high dynamic range video (which delivers a much wider brightness range) and the resulting need to make OLED TVs run more brightly.Īnother relatively recent development that’s made raised screen burn’s profile of late is the most recent test for the problem by online tech testing site, Rtings. LG has confirmed to me that this ‘intended to reduce consumer discomfort in situations where temporary image retention can occur in certain viewing conditions’.Īlso worth noting here is that LG introduced a new feature for its 2018 OLED TVs that can dim the brightness of static picture elements without impacting the rest of the picture.Īll of these measures suggest that screen burn is indeed still considered to be an issue by OLED TV makers. ![]() Next, LG also upset buyers of its 2018 OLED TVs recently by releasing a new firmware update to its most recent generation of OLED TVs that increased the extent and speed with which bright images were dimmed down (as covered here). This made me think that either Sony was reacting to actual cases of screen burn in their own test environments or actual consumer reports, or else they were acting on advice from LG Display, the manufacturer responsible for pretty much all the world’s TV-sized OLED panels. Much to the annoyance of some of the TV's owners. The Sony A8F recently received a firmware update that introduced extra dimming when static objects. And while the brand has since tweaked the update to make it less distracting, the point behind it was surely an attempt to minimize the risk of screen burn affecting its OLED TVs. Sony confirmed that this was a deliberate move. Having sorted that out, let’s get to why I think OLED’s potential susceptibility to screen burn warrants looking at now more than it has before.įirst, Sony upset owners of its OLED TVs earlier in the year (as reported here) by introducing via firmware a new picture dimming algorithm that kicked in distractingly aggressively if a static image component - such as a gaming HUD - was onscreen for around a minute. But the two are not the same in either their cause or the permanency of their effect. ![]() You could even see image retention as a warning that something you’re watching a lot could eventually lead to screen burn, and so needs to be handled with extra care (more on this later). There is it seems to me a connection between image retention and screen burn, to the extent that image elements that cause image retention can lead eventually to screen burn.
