In this paper, we propose a compensation algorithm without neither applying extra pixel circuit nor sensing IC. This method compensates OLED burn‐in with empirical model of emitting material degradation. We extracted modeling parameters from large amount of measured data and applied the proposed algorithm into driver IC. Test results show good performance for improving images sticking level. This algorithm has been applied commercial products of Samsung Display for several years.
