Recent research indicates that while image burn-in is observable in OLED TVs, these instances do not have to be permanent and can be remedied. Contrary to widespread concerns, most cases on OLED TVs do not result in lasting burn-in.
This understanding is based on an in-depth analysis conducted by RTINGS. Image retention may arise due to shifts in the TFT's threshold voltage, with the likelihood being influenced by the TV's internal operations and its power cycle frequency. To substantiate their findings, RTINGS analyzed 100 TVs, simulating ten years of usage, and observed that compensation cycles significantly reduced image retention.
For a more precise evaluation, RTINGS subjected a Sony A90K QD-OLED TV to an intensive test, continuously displaying a CNN stream accompanied by RTINGS branding and specific blocks over 120 hours. Following this, while the TV did exhibit image retention, a subsequent compensation cycle, commonly referred to as "pixel refresh", effectively removed it. Nevertheless, it's worth noting that the activation of this compensation mechanism varies among TV models. For instance, some initiate the process after 4 hours of non-use, while the tested Sony model began only post 6.5 hours.
Specific TV models, including some from LG, do not provide a manual activation option for this cycle. To gain a comprehensive understanding of this topic, resources such as the RTINGS website and their YouTube channel offer extensive explanations.
