Abstract :
We present an electronic monitoring and feedback scheme for an AMOLED display that substantially reduces the appearance of image degradation and increases useful lifetime. We describe the methodology and show results on a 32-inch 1080p OLED display that establishes the benefits. We further explain how the same technique can be used as a diagnostic tool to identify and discriminate among defects introduced during the manufacturing process.
