OLED panels have a shorter lifespan than LCD panels. As evident by the name (Organic Light Emitting Diode) they use an organic compound. This compound breaks down over time. This can be seen as ”burn in” effects that isn’t technically an image burned in, but rather uneven ageing. It’s better described as permanent image retention. The blue subpixels age quicker as blue light contains more energy. This gives the display a yellow tint that increases over time. This can be mitigated by calibration in devices where this is possible, and our vision compensates well for this so it can be hard to notice without a truly white reference. The bigger problem is the uneven aging across the display. For example, areas which show more blue light age quicker than areas that show less.
