  • Publication number: 20210280643
    Abstract: Provided is an organic light emitting display module including an active area, a pad area, and a boundary area between the active area and the pad area. Unlike the active area and the pad area, since the boundary area does not include an inorganic layer, less stress is applied to the boundary area when the boundary area is bent. Display panel pads and touch sensing member pads are disposed at the same height without having a height difference therebetween. Thus, a dummy pad may be added to remove the height difference between the display panel pads and the touch sensing member pads.
