Circular AMOLED panel is largely applied in smart watches. However, it has been challenged that under the difference of smaller size and irregular cutting, the mechanical strength of circular AMOLED panel is no longer suitable for the common definition in the past, compared with the ordinary rectangular shape. 4‐point bending test is a common method to define the cutting strength of a panel, therefore, 4‐point bending test is used to review the strength variation of circular AMOLED panel in this paper. Besides, due to the characteristics of OLED panel, a special fracture mode will also be discussed in this paper.
