Though AMOLED display has been expected as the next generation ideal flat panel display because of its excellent image quality, the AMOLED market has been still limited. This means that AMOLED has not had sufficient competitiveness with LCD yet. There are two critical problems for AMOLED to overcome to compete with LCD. One is Mura problem caused by TFT characteristics deviation in the backplane and the other is short life time of image sticking. In this paper, we will review various approaches to overcome these two critical problems and discuss the practicality of the methods.
