There is a bad performance in the image quality of AMOLED display, which is the graininess and the non‐uniformity brought by the graininess. This phenomenon is called Sandy Mura in this paper. After systematic research and analysis, Sandy Mura is divided into three types. These three types of Sandy Mura interfere with each other in observation and judgment, making adverse improvement extremely difficult. In this study, the main elements for several Sandy mura types were experimentally verified, and their distinct mechanisms and models were developed. According to the models, the improvement plan was proposed. After a series of improvements, Sandy mura was finally effectively improved.
