  • Patent number: 10418425
    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.

  • Patent number: 10306789
    Abstract: A display apparatus may include a display unit that includes a bottom chassis made of metal, a metal stand to support the display unit, a fixing bracket that is fixed to the bottom chassis and the stand, and an insulating member that electrically separates the fixing bracket and the bottom chassis. Because the fixing bracket and the bottom chassis are electrically separated from each other via the insulating member, electromagnetic noise that is generated in the bottom chassis may be prevented from being transmitted to the stand despite the stand being mounted on the fixing bracket.
