  • Patent number: 7196750
    Abstract: In a flat display apparatus capable of decreasing an emission of an electromagnetic radiation, a flat display apparatus includes a flat display panel, a first receiving container, a driving part, a second receiving container and a ground member. The flat display panel displays an image. The first receiving container receives the flat display panel. The driving part is disposed on the first receiving container to drive the flat display panel. The second receiving container covers the driving part to block an electromagnetic radiation radiated from the driving part. The ground member is formed with the second receiving container to electrically connect the first receiving container to the second receiving container. Therefore, the second receiving container is electrically connected to an earth potential through the ground member and the first receiving container to decrease the emission of the electromagnetic radiation.
