In ultra-high-definition AMOLED displays, external compensation improves burn-in by varying the current through the driving TFT. However, sensing the current through the driving TFT for all pixels is time-consuming because of the increased number of scanning lines. Hence, in this study, we propose an external compensation technique that provides rapid feedback.
