Back in June 2012 I reported from SID on Ignis' Max Life technology. Max Life provides external compensation - that deals with OLED burn-in. The idea is to keep track of how much each pixel was used, and so it's possible to calculate the brightness loss in that particular pixel, and then drive this particular pixel correctly - to compensate. Ignis now released a nice video showing a 20" AMOLED panel (their own a-Si prototypes made by RiTDisplay) with a burn-in logo. When Max Life is turned on, the logo disappears:
Ignis explains that while Max Life theoretically makes the "eventual" lifetime (until the display burns out completely) worse, in practice it helps to make the device usable longer. Ignis says that the main problem is non-uniformity in brightness and not actual brightness.
