OLED TVs beat LCD TVs in 3-year longevity test
Rtings has run 102 TVs at maximum brightness for 3 years by displaying a news channel that constantly shows a news ticker bar at the bottom to test for burn-in. As expected, burn-in remains an issue, but LCDs are also struggling with serious problems after 18,000 hours of usage.
Out of 102 TVs, 20 have failed entirely after 3 years, and 24 others have at least partially failed and are barely usable. However, the test also shows that most television sets easily survive 10,000 hours of operation, which corresponds to a lifespan of over 3 years if the TV is used for 8 hours every single day. LG and TCL had the lowest failure rate in this specific test, but due to the relatively small number of devices tested, the statistical significance is limited.
Most problems were found in TVs with LED backlight without local dimming. Almost 60% of these models struggled with defects, and in many cases, one or more LEDs burned out. In comparison, failures are extremely rare in OLED TVs. The test also illustrates that burn-in is not a problem when watching dynamic content. Static content, such as the previously mentioned news ticker, can create visible ghosting after long periods of use at high brightness. In practice, this is likely primarily relevant for PC monitors and not televisions.
Moreover, Rtings’ longevity shows that OLED TVs have the longest lifespan of all TV types and don’t develop problems as often. While the test shows a clear correlation between panel, backlight type and failure rate, there is no clear connection between the price and the lifespan of a television set.
