In this work, we report 30‐inch 4K rollable AMOLED display, featuring IGZO‐TFT backplane and side by side evaporation process with etching fine metal mask. Adaptive temporal aperture control is used to improve motion image quality. Roll‐up mechanics have various parts to get its flatness, quietness and stability. Finally, we demonstrate a large rollable display, showing motion images clearly and rolling up compact with a radius of 20 mm.
