Does anyone out there know anything about "burn-in" ? I know that it is a phenomenon that can occur if an OLED TV has a static image displayed on it for an excessively long time; whereby a ghost of that static image can be seen on the TV screen even after that image is no longer sent to the TV. If that ghost image is temporary, then that phenomenon is known as "image retention". If the ghost image is permanent, then that phenomenon is known as "burn-in". But what specifically happens with "burn-in" ? Is the ghost image burnt into the glass panel that covers the TV screen ? (I doubt it.). But if not the glass panel, then which layer of the stack experiences the burn-in ? Is it one of the host material layers ? Or is it one of the emissive materials that experiences the burn-in ? If it is one of the emissive materials, is "burn-in" the right term, or would "burn-out" be closer to what actually happens ? Or is it the emissive material drivers that burn out ? It seems like the solutions for "burn-in" offered so far have been topical in nature. Is a solution possible at a more specific level ? Samsung & Friends have been shouting about the risks of burn-in at the top of their lungs. Now it appears that they will be making an OLED TV variant. Do they know something ?
