Abstract

<abstract abstract-type="main"> <title>Abstract</title> <p>In this paper, we provide the best way to drive large‐size OLED panel. This method compensates for variations in the on‐current and threshold voltage by extracting the TFT characteristics of each pixel of the panel. It also compensates the time‐dependent degradation characteristics of the TFT. From the extracted characteristics, corrected image‐data are generated that is composed gain and offset. By driving in the data which is corrected, it is possible to improve the uniformity of brightness and increase the life‐time of the panel. Consequently, 55‐inch OLED TV was manufactured and commercialized. For the commercialization of large‐size OLED TV, this driving method is very suitable and it will become an important.</p> </abstract>
