  • Patent number: 7773372
    Abstract: An organic light emitting diode (OLED) display has an increased mechanical strength by improving the shape of a bezel combined to a panel assembly. The OLED display includes a panel assembly having a display area and a pad area, and a bezel accommodating the panel assembly. The bezel includes a bottom part on which the panel assembly is mounted, a side wall provided on a side of the bezel, and a hemming flange provided at another side of the bezel on which the side wall is not provided. The panel assembly is mounted in a manner that the pad area is turned towards the another side.
