Image sticking has always been one of the pain points in panel manufacturing. In this study, mechanism of IC side artifacts on commonly used small size liquid crystal displays (LCD) screens during image sticking reliability test at room temperature was analyzed and experimentally verified, and some improvement measures were proposed.
