Abstract:
A burn-in compensation method and a computing device configured for burn-in compensation is disclosed. The burn-in compensation can minimize or eliminate a burn-in of an OLED display having areas with different pixel densities. Each area of the OLED display may be divided into zones that include one or more pixels and a burn-in factor may be computed for the zones. A limiting burn-in factor may be determined from a limiting zone that exhibits the highest burn-in. Other zones with burn-in factors that area significantly different from the limiting burn-in factor can be adjusted so that the pixels in the adjusted zones can be driven to radiate similar light at a power similar to the liming zone. The burn-in compensation may be performed for each area and a transition region may be created between areas to minimize light artifacts after burn-in compensation.
