Since the static image of the screen is displayed for a long time, it may cause a burn-in phenomenon, which may cause some images to be "swinged" on the screen. It is reported that at the SID Display Week 2018 (American Display Week) event held in Los Angeles at the end of May, LG's 65-inch OLED TV showed signs of burning. Nanosys revealed that the TV was purchased from the market three weeks before the start of the show (SID 2018), and the power-on time before the event did not exceed 60 hours.
However, this is not the first time that the LG OLED display has burned. At the beginning of May, the OLED TV in the Incheon Airport terminal in South Korea was installed and used only at the beginning of the year.
LG said that this problem is mainly caused by factory problems, and some monitors are more prone to problems than other monitors. It is unclear whether this product issue is inherent in technology or simply a factory problem that LG claims. In order to find out the truth, Sony also purchased related OLED panels from LG. It is reported that since the purchase of LG OLED panels, some of Sony's large OLED displays have also suffered from burn-in problems. Therefore, it can be seen that the burn-in is probably caused by the inherent problems of the technology and the way the product is produced.
It is expected that burn-in will not become a problem for Micro LED or Mini LED display, at least not yet. However, there are several major production challenges that need to be overcome to prepare large Micro LED displays. The main problem facing the market for Micro LED displays is the huge shift in Micro LEDs. At present, the large display products on the market are technically still Mini LED models, not Micro LED display products.
